No. 07/844,732 filed Mar. 2, 1992, now U.S. Pat. No. 5,231,975 which is a divisional of application Ser. No. 07/484,560, now U.S. Pat. No. 5,115,805, filed Feb. 23, 1990.TECHNICAL FIELDThis invention relates generally to the field of drug delivery. More particularly, the invention relates to a method of enhancing the rate of permeation of topically, transmucosally or transdermally applied materials using high frequency ultrasound.BACKGROUNDThe delivery of drugs through the skin ("transdermal drug delivery" or "TDD") provides many advantages; primarily, such a means of delivery is a comfortable, convenient and non-invasiveway of administering drugs. The variable rates of absorption and metabolism encountered in oral treatment are avoided, and other inherent inconveniences--e.g., gastrointestinal irritation and the like--are eliminated as well. Transdermal drug delivery also makes possible a high degree of control over blood concentrations of any particular drug.Skin is a structurally complex, relatively impermeable membrane. Molecules moving from the environment into and through intact skin must first penetrate the stratum corneum and any material on its surface. They must then penetrate the viable epidermis, the papillary dermis, and the capillary walls into the blood stream or lymph channels. To be so absorbed, molecules must overcome a different resistance to penetration in each type of tissue. Transport across the skin membrane is thus a complex phenomenon. However, it is the stratum corneum, a layer approximately 5-15 micrometers thick over most of the body, which presents the primary barrier to absorption of topical compositions or transdermally administered drugs. It is believed to be the high degree of keratinization within its cells as well as their dense packing and cementation by ordered, semicrystalline lipids which create in many cases a substantially impermeable barrier to drug penetration. Applicability of transdermal drug delivery is thus presently limited, because the skin is such an excellent barrier to the ingress of topically applied materials. For example, many of the new peptides and proteins now produced as a result of the biotechnology revolution cannot be delivered across the skin in sufficient quantities due to their naturally low rates of skin permeability.Various methods have been used to increase skin permeability, and in particular to increase the permeability of thestratum corneum (i.e., so as to achieve enhanced penetration, through the skin, of the drug to be administered transdermally). The primary focus has been on the use of chemical enhancers, i.e., wherein drug is coadministered with a penetration enhancing agent (or "permeation enhancer"). While such compounds are effective in increasing the rate at which drug is delivered through the skin, there are drawbacks with many permeation enhancers which limit their use. For example, many permeation enhancers are associated with deleterious effects on the skin (e.g., irritation). In addition, control of drug delivery with chemical enhancement can be quite difficult.Iontophoresis has also been used to increase the permeability of skin to drugs, and involves (1) the application of an external electric field, and (2) topical delivery of an ionized form of drug (or of a neutral drug carried with the water flux associated with ion transport, i.e., via "electroosmosis"). While permeation enhancement via iontophoresis has, as with chemical enhancers, been effective, there are problems with control of drug delivery and the degree of irreversible skin damage induced by the transmembrane passage of current.The presently disclosed and claimed method involves the use of ultrasound to decrease the barrier function of the stratum corneum and thus increase the rate at which a drug may be delivered through the skin. "Ultrasound" is defined as mechanical pressure waves with frequencies above 20,000 Hz (see, e.g., H. Lutz et al., Manual of Ultrasound: 1. Basic Physical and Technical Principles (Berlin: Springer-Verlag, 1984)).As discussed by P. Tyle et al. in Pharmaceutical Research 6(5):355-361 (1989), drug penetration achieved via "sonophoresis" (the movement of drugs through skin under theinfluence of an ultrasonic perturbation; see D. M. Skauen and G. M. Zentner, Int. J. Pharmaceutics 20:235-245 (1984)), is believed to result from thermal, mechanical and chemical alteration of biological tissues by the applied ultrasonic waves. Unlike iontophoresis, the risk of skin damage appears to be low.Applications of ultrasound to drug delivery have been discussed in the literature. See, for example: P. Tyle et al., supra (which provides an overview of sonophoresis); S. Miyazaki et al., J. Pharm. Pharmacol. 40:716-717 (1988) (controlled release of insulin from a polymer implant using ultrasound); J. Kost et al., Proceed. Intern. Symp. Control. Rel. Bioact. Mater.16(141):294-295 (1989) (overview of the effect of ultrasound on the permeability of human skin and synthetic membranes); H. Benson et al., Physical Therapy 69(2):113-118 (1989) (effect of ultrasound on the percutaneous absorption of benzydamine); E. Novak, Arch. Phys. Medicine & Rehab. 45:231-232 (1964) (enhanced penetration of lidocaine through intact skin using ultrasound); J. E. Griffin et al., Amer. J. Phys. Medicine 44(1):20-25 (1965) (ultrasonic penetration of cortisol into pig tissue); J. E. Griffin et al., J. Amer. Phys. Therapy Assoc.46:18-26 (1966) (overview of the use of ultrasonic energy in drug therapy); J. E. Griffin et al., Phys. Therapy 47(7):594-601 (1967) (ultrasonic penetration of hydrocortisone); J. E. Griffin et al., Phys. Therapy 48(12):1336-1344 (1968) (ultrasonic penetration of cortisol into pig tissue); J. E. Griffin et al., Amer. J. Phys. Medicine 51(2):62-72 (1972) (same); J. C. McElnay, Int. J. Pharmaceutics 40:105-110 (1987) (the effect of ultrasound on the percutaneous absorption of fluocinolone acetonide); and C. Escoffier et al., Bioeng. Skin 2:87-94 (1986) (in vitro study of the velocity of ultrasound in skin).In addition to the aforementioned art, U.S. Pat. Nos. 4,767,402 and 4,780,212 to Kost et al. relate specifically to the use of specific frequencies of ultrasound to enhance the rate of permeation of a drug through human skin or through a synthetic membrane.While the application of ultrasound in conjunction with drug delivery is thus known, results have for the most part been disappointing, i.e., enhancement of skin permeability has been relatively low.SUMMARY OF THE INVENTIONThe present invention provides a novel method for enhancing the rate of permeation of a given material through a selected intact area of an individual's body surface. The method comprises contacting the selected intact area with the material and applying ultrasound to the contacted area. The ultrasound preferably has a frequency of above about 10 MHz, and is continued at an intensity and for a period of time sufficient to enhance the rate of permeation of the material into and through the body surface. The ultrasound can also be used to pretreat the selected area of the body surface in preparation for drug delivery, or for diagnostic purposes, i.e., to enable non-invasive sampling of physiologic material beneath the skin or body surface.In addition to enhancing the rate of permeation of a material, the present invention involves increasing the permeability of a biological membrane such as the stratum corneum by applying ultrasound having a frequency of above about 10 MHz to the membrane at an intensity and for a period of time sufficient to give rise to increased permeability of the membrane. Once the permeability of the membrane has been increased, it is possible to apply a material thereto and obtain an increased rate of flowof the material through the membrane.It is accordingly a primary object of the invention to address the aforementioned deficiencies of the prior art by providing a method of enhancing the permeability of biological membranes and thus allow for an increased rate of delivery of material therethrough.It is another object of the invention to provide such a method which is effective with or without chemical permeation enhancers.It is still another object of the invention to minimize lag time in such a method and provide a relatively short total treatment time.It is yet another object of the invention to provide such a method in which drug delivery is effected using ultrasound.It is a further object of the invention to enable sampling of tissue beneath the skin or other body surface by application of high frequency (>10 MHz) ultrasound thereto.A further feature of the invention is that it preferably involves ultrasound of a frequency greater than about 10 MHz.Additional objects, advantages and novel features of the invention will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following, or may be learned by practice of the invention.BRIEF DESCRIPTION OF THE DRAWINGSFIGS. 1A, 1B and 1C are theoretical plots of energy dissipation within the skin barrier versus frequency of applied ultrasound.FIGS. 2, 3 and 4 are graphic representations of the amount of salicylic acid recovered from the stratum corneum after ultrasound treatment at different frequencies.FIGS. 5 and 6 represent the results of experiments similar to those summarized in FIGS. 2, 3 and 4, but with a shorter treatment time.FIGS. 7, 8, 9 and 10 are plots of enhancement versus "tape-strip number," as described in the Example.FIG. 11 illustrates the effect of ultrasound on the systemic availability of salicylic acid following topical application.DETAILED DESCRIPTION OF PREFERRED EMBODIMENTSBefore the present method of enhancing the rate of permeation of a material through a biological membrane and enhancing the permeability of membranes using ultrasound are disclosed and described, it is to be understood that this invention is not limited to the particular process steps and materials disclosed herein as such process steps and materials may, of course, vary. It is alto to be understood that the terminology used herein is used for purpose of describing particular embodiments only and is not intended to be limiting since the scope of the present invention will be limited only by the appended claims.It must be noted that as used in this specification and the appended claims, the singular forms "a", "an" and "the" include plural reference unless the context clearly dictates otherwise. Thus, for example, reference to "a drug" includes mixtures of drugs and their pharmaceutically acceptable salts, reference to "an ultrasound device" includes one or more ultrasound devices of the type necessary for carrying out the present invention, and reference to "the method of administration" includes one or more different methods of administration known to those skilled in the art or which will become known to those skilled in the art upon reading this disclosure.In one aspect of the invention a method is provided forenhancing the permeation of a given material such as a drug, pharmacologically active agent, or diagnostic agent into and/or through a biological membrane on an individual's body surface, which method comprises: (a) contacting the membrane with the chosen material in a pharmacologically acceptable carrier medium; and (b) applying ultrasound of an intensity and for a treatment time effective to produce delivery of the material through the membrane. The material is preferably a drug and it is preferable to obtain a desired blood level of the drug in the individual. The ultrasound is of a frequency and intensity effective to increase the permeability of the selected area to the applied drug over that which would be obtained without ultrasound. The ultrasound preferably has a frequency of more than 10 MHz, and may be applied either continuously or pulsed, preferably continuously. The ultrasound may be applied to the skin either before or after application of the drug medium so long as administration of the ultrasound and the drug medium is relatively simultaneous, i.e., the ultrasound is applied within about 6, more preferably within about 4, most preferably within about 2 minutes of drug application.The invention is useful for achieving transdermal permeation of pharmacologically active agents which otherwise would be quite difficult to deliver through the skin or other body surface. For example, proteinaceous drugs and other high molecular weight pharmacologically active agents are ideal candidates for transdermal, transmucosal or topical delivery using the presently disclosed method. In an alternative embodiment, agents useful for diagnostic purposes may also be delivered into and/or through the body surface using the present method.The invention is also useful as a non-invasive diagnostictechnique, i.e., in enabling the sampling of physiologic material from beneath the skin or other body surface and into a collection (and/or evaluation) chamber.The present invention will employ, unless otherwise indicated, conventional pharmaceutical methodology and more specifically conventional methodology used in connection with transdermal delivery of pharmaceutically active compounds and enhancers.In describing the present invention, the following terminology will be used in accordance with the definitions set out below.A "biological membrane" is intended to mean a membrane material present within a living organism which separates one area of the organism from another and, more specifically, which separates the organism from its outer environment. Skin and mucous membranes are thus included."Penetration enhancement" or "permeation enhancement" as used herein relates to an increase in the permeability of skin to a material such as a pharmacologically active agent, i.e., so as to increase the rate at which the material permeates into and through the skin. The present invention involves enhancement of permeation through the use of ultrasound, and, in particular, through the use of ultrasound having a frequency of greater than 10 MHz."Transdermal" (or "percutaneous") shall mean passage of a material into and through the skin to achieve effective therapeutic blood levels or deep tissue therapeutic levels. While the invention is described herein primarily in terms of "transdermal" administration, it will be appreciated by those skilled in the art that the presently disclosed and claimed methodalso encompasses the "transmucosal" and "topical" administration of drugs using ultrasound. "Transmucosal" is intended to mean passage of any given material through a mucosal membrane of a living organism and more specifically shall refer to the passage of a materialfrom the outside environment of the organism, through a mucous membrane and into the organism. "Transmucosal" administration thus includes delivery of drugs through either nasal or buccal tissue. By "topical" administration is meant local administration of a topical pharmacologically active agent to the skin as in, for example, the treatment of various skin disorders or the administration of a local anaesthetic. "Topical" delivery can involve penetration of a drug into the skin but not through it, i.e., topical administration does not involve actual passage of a drug into the bloodstream."Carriers" or "vehicles" as used herein refer to carrier materials without pharmacological activity which are suitable for administration with other pharmaceutically active materials, and include any such materials known in the art, e.g., any liquid, gel, solvent, liquid diluent, solubilizer, or the like, which is nontoxic and which does not interact with the drug to be administered in a deleterious manner. Examples of suitable carriers for use herein include water, mineral oil, silicone, inorganic gels, aqueous emulsions, liquid sugars, waxes, petroleum jelly, and a variety of other oils and polymeric materials.By the term "pharmacologically active agent" or "drug" as used herein is meant any chemical material or compound suitable for transdermal or transmucosal administration which can either (1) have a prophylactic effect on the organism and prevent an undesired biological effect such as preventing aninfection, (2) alleviates a condition caused by a disease such as alleviating pain caused as a result of a disease, or (3) either alleviates or completely eliminates the disease from the organism. The effect of the agent may be local, such as providing for a local anaesthetic effect or it may be systemic. Such substances include the broad classes of compounds normally delivered through body surfaces and membranes, including skin. In general, this includes: anti-infectives such as antibiotics and antiviral agents; analgesics and analgesic combinations; anorexics; antihelminthics; antiarthritics; antiasthmatic agents; anticonvulsants; antidepressants; antidiabetic agents; antidiarrheals; antihistamines; antiinflammatory agents; antimigraine preparations; antinauseants; antineoplastics; antiparkinsonism drugs; antipruritics; antipsychotics; antipyretics; antispasmodics; anticholinergics; sympathomimetics; xanthine derivatives; cardiovascular preparations including potassium and calcium channel blockers, beta-blockers, and antiarrhythmics; antihypertensives; diuretics; vasodilators including general coronary, peripheral and cerebral; central nervous system stimulants; cough and cold preparations, including decongestants; hormones such as estradiol and other steroids, including corticosteroids; hypnotics; immunosuppressives; muscle relaxants; parasympatholytics; psychostimulants; sedatives; and tranquilizers. By the method of the present invention, both ionized and nonionzed drugs may be delivered, as can drugs of either high or low molecular weight.Proteinaceous and polypeptide drugs represent a preferred class of drugs for use in conjunction with the presently disclosed and claimed invention. Such drugs cannot generally be administered orally in that they Are often destroyed in the G.I.tract or metabolized in the liver. Further, due to the high molecular weight of most polypeptide drugs, conventional transdermal delivery systems are not generally effective. It is also desirable to use the methodof the invention in conjunction with drugs to which the permeability of the skin is relatively low, or which give rise to a long lag-time (application of ultrasound as described herein has been found to significantly reduce the lag-time involved with the transdermal administration of most drugs).By a "therapeutically effective" amount of a pharmacologically active agent is meant a nontoxic but sufficient amount of a compound to provide the desired therapeutic effect. The desired therapeutic effect may be a prophylactic effect, in preventing a disease, an effect which alleviates a system of the disease, or a curative effect which either eliminates or aids in the elimination of the disease.As noted above, the present invention is a method for enhancing the rate of permeation of a drug through an intact area of an individual's body surface, preferably the human skin. The method involves transdermal administration of a selected drug in conjunction with ultrasound. Ultrasound causes thermal, mechanical and chemical alterations of biological tissue, thereby enhancing the rate of permeation of a given material therethrough.While not wishing to be bound by theory, applicants propose that the use of higher frequency ultrasound as disclosed herein specifically enhances the permeation of the drug through the outer layer of skin, i.e., the stratum corneum, by causing momentary and reversible perturbations within (and thus short-term, reversible reduction in the barrier function of) the layer ofthe stratum corneum. It will be appreciated by those skilled in the art of transdermal drug delivery that a number of factors related to the present method will vary with the drug to be administered, the disease or injury to be treated, the age of the selected individual, the location of the skin to which the drug is applied, and the like.As noted above, "ultrasound" is ultrasonic radiation of a frequency above 20,000 Hz. As may be deduced from the literature cited above, ultrasound used for most medical purposes typically employs frequencies ranging from 1.6 to about 10 MHz. The present invention, by contrast, employs ultrasound frequencies of greater than about 10 MHz, preferably in the range of about 15 to 50 MHz, most preferably in the range of about 15 to 25 MHz. It should be emphasized that these ranges are intended to be merely illustrative of the preferred embodiment; in some cases higher or lower frequencies may be used.The ultrasound may be pulsed or continuous, but is preferably continuous when lower frequencies are used. At very high frequencies, pulsed application will generally be preferred so as to enable dissipation of generated heat.The preferred intensity of the applied ultrasound is less than about 5.0 W/cm.sup.2, more preferably is in the range of about 0.01 to 5.0 W/cm.sup.2, and most preferably is in the range of 0.05 to 3.0 W/cm.sup.2. The total treatment time, i.e., the period over which drug and ultrasound are administered, will vary depending on the drug administered, the disease or injury treated, etc., but will generally be on the order of about 30 seconds to 60 minutes, preferably 5 to 45 minutes, more preferably 5 to 30 minutes, and most preferably 5 to 10minutes. It should be noted that the aforementioned ranges represent suggested, or preferred, treatment times, but are not in any way intended to be limiting. Longer or shorter times may be possible and in some cases desirable. Virtually any type of device may be used to administer the ultrasound, providing that the device is callable of producing the higher frequency ultrasonic waves required by the present method. A device will typically have a power source such as a small battery, a transducer, a reservoir in which the drug medium is housed (and which may or may not be refillable), and a means to attach the system to the desired skin site.As ultrasound does not transmit well in air, a liquid medium is generally needed to efficiently and rapidly transmit ultrasound between the ultrasound applicator and the skin. As explained by P. Tyle et al., cited above, the selected drug medium should contain a "coupling" or "contacting" agent typically used in conjunction with ultrasound. The coupling agent should have an absorption coefficient similar to that of water, and furthermore be nonstaining, nonirritating to the skin, and slow drying. It is clearly preferred that the coupling agent retain a paste or gel consistency during the time period of ultrasound administration so that contact is maintained between the ultrasound source and the skin. Examples of preferred coupling agents are mixtures of mineral oil and glycerine and propylene glycol, oil/water emulsions, and a water-based gel. A solid-state, non-crystalline polymeric film having the above-mentioned characteristics may also be used. The drug medium may also contain a carrier or vehicle, as defined alone.A transdermal patch as well known in the art may be used in conjunction with the present invention, i.e., to deliver the drugmedium to the skin. The "patch", however, must have the properties of the coupling agent as described in the preceding paragraph so as to enable transmission of the ultrasound from the applicator, through the patch, to the skin.As noted earlier in this section, virtually any chemical material or compound suitable for transdermal, transmucosal or topical administration may be administered using the present method. Again, the present invention is particularly useful to enhance delivery of proteinaceous and other high molecular weight drugs.The method of the invention is preferably carried out as follows. The drug medium, i.e., containing the selected drug or drugs in conjunction with the coupling agent and optionally a carrier or vehicle material, is applied to an area of intact body surface. Ultrasound preferably having a frequency greater than about 10 MHz may be applied before or after application of the drug medium, but is preferably applied immediately before application of the drug so as to "pretreat" the skin prior to drug administration.It should also be pointed out that the present method may be used in conjunction with a chemical permeation enhancer as known in the art, wherein the ultrasound enables the use of much lower concentrations of permeation enhancer--thus minimizing skin irritation and other problems frequently associated with such compounds--than would be possible in the absence of ultrasound. The permeation enhancer may be incorporated into the drug medium or it maybe applied in a conventional transdermal patch after pretreatment of the body surface with ultrasound.The present invention may also be used in conjunction with。

面料减量的英语
面料减量的英语Fabric Reduction: A Sustainable Approach to FashionThe fashion industry has long been a significant contributor to environmental degradation, with the production and disposal of textiles generating massive amounts of waste and greenhouse gas emissions. In recent years, however, a growing awareness of the need for sustainable practices has led to the emergence of a new trend: fabric reduction. This approach aims to minimize the use of raw materials in the manufacturing process, ultimately reducing the environmental impact of the fashion industry.One of the primary drivers behind fabric reduction is the recognition that the traditional model of fashion production is unsustainable. The industry's reliance on fast fashion, with its emphasis on churning out new styles at a rapid pace, has led to an overabundance of clothing and a significant waste problem. According to the United Nations Environment Programme, the fashion industry is responsible for approximately 10% of global carbon emissions and is the second-largest consumer of the world's water supply.Fabric reduction seeks to address these issues by focusing on the efficient use of materials. This can be achieved through a variety of strategies, including:1. Design optimization: Fashion designers are increasingly exploring ways to create garments that require less fabric, without compromising on style or functionality. This may involve the use of innovative pattern-making techniques, the incorporation of modular designs, or the exploration of alternative materials.2. Waste reduction: In the traditional manufacturing process, a significant amount of fabric is often discarded as waste. Fabric reduction initiatives aim to minimize this waste by optimizing cutting patterns, reusing leftover materials, and implementing closed-loop recycling systems.3. Material selection: The choice of raw materials can have a significant impact on the environmental footprint of a garment. Fabric reduction advocates for the use of sustainable, biodegradable, or recycled materials, which can reduce the demand for virgin resources and minimize the carbon footprint of the production process.4. Garment longevity: By creating garments that are designed to last,fabric reduction can help to reduce the overall consumption of clothing. This may involve the use of higher-quality materials, the incorporation of timeless designs, and the provision of repair and maintenance services.One of the most prominent examples of fabric reduction in action is the work of sustainable fashion brands such as Reformation and Eileen Fisher. These companies have made a concerted effort to minimize the use of raw materials in their production processes, while also prioritizing the use of eco-friendly and recycled fabrics.Reformation, for instance, has developed a proprietary fabric-reduction technique that allows them to create garments with up to 75% less fabric than traditional methods. This not only reduces waste but also lowers the brand's carbon footprint and water usage. Similarly, Eileen Fisher has implemented a closed-loop recycling program, where customers can return their used Eileen Fisher garments, which are then broken down and repurposed into new clothing.The benefits of fabric reduction extend beyond the environmental realm, as it can also have a positive impact on the social and economic aspects of the fashion industry. By reducing the demand for raw materials, fabric reduction can help to alleviate the exploitation of garment workers, who often toil in poor workingconditions to meet the needs of the fast-fashion industry. Additionally, the creation of circular, closed-loop systems can generate new job opportunities in the areas of recycling, repair, and sustainable manufacturing.Despite the promising potential of fabric reduction, there are still significant challenges that must be overcome. One of the primary hurdles is the need for widespread consumer education and behavioral change. Many consumers have become accustomed to the fast-paced, disposable nature of the fashion industry, and shifting these mindsets will require a concerted effort by brands, policymakers, and sustainability advocates.Furthermore, the implementation of fabric reduction strategies can be complex and resource-intensive, requiring significant investment in research, development, and infrastructure. Smaller and independent brands may face particular challenges in adopting these practices, as they often lack the financial and logistical resources of larger, established companies.Despite these challenges, the momentum behind fabric reduction is steadily growing, as the fashion industry and consumers alike recognize the urgent need for more sustainable practices. As more brands and designers embrace the principles of fabric reduction, it is likely that we will see a significant shift in the way that clothing isproduced, consumed, and disposed of.In conclusion, fabric reduction represents a promising approach to addressing the environmental and social impacts of the fashion industry. By minimizing the use of raw materials, reducing waste, and promoting the longevity of garments, this strategy has the potential to transform the fashion landscape and pave the way for a more sustainable future. As the industry continues to evolve, it is crucial that all stakeholders – from designers and manufacturers to consumers and policymakers – work together to support and amplify the fabric reduction movement.。
香菇多糖提高免疫力的原理
香菇多糖提高免疫力的原理英文回答:Mushrooms are known for their immune-boosting properties, and one of the key reasons behind this is their high content of polysaccharides. Polysaccharides are complex carbohydrates that have been shown to have immunomodulatory effects in the body.When we consume mushrooms, the polysaccharides present in them interact with our immune cells, such as macrophages and natural killer cells. These immune cells play a crucial role in defending our body against pathogens and foreign invaders. The polysaccharides help to activate and enhance the function of these immune cells, thereby improving our immune response.One of the ways in which polysaccharides boost our immune system is by increasing the production of cytokines. Cytokines are signaling molecules that regulate the immuneresponse. They help to coordinate the activities of different immune cells and promote inflammation when necessary to fight off infections. By stimulating the production of cytokines, polysaccharides help to strengthen our immune system and improve its ability to fight off diseases.Another mechanism through which polysaccharides enhance immunity is by increasing the production of antibodies. Antibodies are proteins produced by our immune system in response to the presence of antigens, such as bacteria or viruses. They help to neutralize and eliminate these antigens from our body. Polysaccharides have been found to stimulate the production of antibodies, thereby enhancing our immune defense.Additionally, polysaccharides have been shown to have antioxidant properties. Oxidative stress, caused by an imbalance between the production of free radicals and the body's antioxidant defenses, can weaken the immune system. By acting as antioxidants, polysaccharides help to reduce oxidative stress and protect our immune cells from damage,thus improving immune function.In summary, the polysaccharides found in mushrooms play a significant role in enhancing our immune system. They activate and enhance the function of immune cells, increase the production of cytokines and antibodies, and provide antioxidant protection. By incorporating mushrooms into our diet, we can harness these immune-boosting benefits and support our overall health.中文回答:香菇以其提高免疫力的特性而闻名,其中的关键原因之一是其高含量的多糖。

杀孢子剂的储存要求
杀孢子剂的储存要求英文回答:Storage requirements for fungicides vary depending on the specific type of fungicide and its formulation. However, there are some general guidelines that can be followed to ensure proper storage and handling of fungicides, including sporicides.1. Temperature: Fungicides should be stored in a cool, dry place away from direct sunlight and extreme temperatures. High temperatures can cause degradation ofthe active ingredients in fungicides, reducing their effectiveness. It is recommended to store fungicides at temperatures between 10°C and 25°C.2. Moisture: Fungicides should be kept in a dry environment to prevent moisture absorption. Moisture can lead to clumping or caking of the fungicide, making it difficult to measure and apply accurately. Additionally,moisture can also promote microbial growth, potentially reducing the efficacy of the fungicide. It is advisable to store fungicides in airtight containers or original packaging to protect them from moisture.3. Ventilation: Adequate ventilation is crucial when storing fungicides. Proper ventilation helps prevent the buildup of volatile organic compounds (VOCs) that may be emitted by some fungicides. VOCs can be harmful if inhaled in high concentrations. Therefore, it is recommended to store fungicides in a well-ventilated area, preferably with access to fresh air.4. Separate Storage: Fungicides should be stored separately from other chemicals, particularly those that are incompatible. Mixing fungicides with incompatible chemicals can lead to chemical reactions, potentially resulting in the release of toxic gases or other hazardous situations. It is essential to read the product labels and follow the manufacturer's instructions for proper storage and handling.5. Child and Pet Safety: Fungicides, like any other chemical, should be kept out of reach of children and pets. They should be stored in a secure location, preferably in a locked cabinet or storage area. This precaution helps prevent accidental ingestion or exposure to the fungicide, which can be harmful.中文回答:杀孢子剂的储存要求因具体种类和配方而异。

天然植物化妆品防腐剂分析报告
天然植物化妆品防腐剂分析报告天然植物化妆品防腐剂简介目前,化妆品原料行业内防腐剂技术并无太大突破,主流防腐剂供应商目前推出新产品主要有两种方式:专利技术和天然防腐剂。
所谓专利技术,也就是防腐剂供应商将几种不同的防腐剂复配后,若能取得好的防腐杀菌性能,则申请专利保护,并作为一个防腐剂新产品来卖。
而另一种新产品供给方式就是推出天然防腐剂。
当然,不少植物提取物的原料供应商也有这类产品。
天然植物防腐剂是以天然植物中提取出的抑菌有效成分为主要活性成分,配以起到协同抑菌作用的辛二醇、乙基己基甘油等,组成不含常规化学防腐剂但具有良好防腐抑菌效果的产品。
例如:茶树精油类,具有抗发炎抗菌功效,抑制细菌生长,不会对人体造成伤害,也是市面上常看到的天然防腐剂。
国内外市场现状日本的MARUZEN KASEI KK(丸善化成株式会社)早在1986年申请专利“Natural preservative”(天然防腐剂),该发明天然防腐剂组合物主要是由甘草萃取物以及蜂胶提取物作为活性成分,该防腐剂应用于食物、药物、化妆品中。
韩国的“Biospectrum,Inc.”成立于2000年,是一家创新专业化妆品成分的主要开发商和供应商,于2007年4月3日申请专利“Natural composite preservatives”,公开号:US20070231403A1。
本发明公开了一种天然复合防腐剂,由茶树,洋甘菊、柑橘,辛夷、蜂胶、罗汉柏、白柳或其组合的萃取物组成,该天然复合防腐剂具有强大的广谱抗菌活性,且对身体无害,无毒无刺激性,可以在化妆品、医药,食品中应用。
科丝美诗(COSMAX)是韩国第一大的化妆品制造厂居世界前10位,于2004年4月7日在韩国申请发明名称为“Natural antiseptic agent”的专利,公开号:KR1020050098548A,本发明涉及艾属科植物提取液包含的天然防腐剂,应用于食品、化妆品、医药和木材等方面。
