为了确定不同的含银医用敷料在银的释放量和释放速度上的区别,分析了几种含银医用敷料释放银离子的性能。介绍了测试抗菌性能的3种方法,并总结了含银医用敷料的抗菌性能及临床疗效。结果显示,不同的伤口对银离子的释放量有不同的要求。烧伤病人的伤口特别容易受感染,因此在烧伤伤口上使用的含银医用敷料的银离子释放量高,在伤口上可以维持较高浓度的银。在高吸湿性的医用敷料中,细菌和伤口渗出液一起被吸进敷料,从敷料上释放出少量的银离子即可达到抗菌的目的。 相似文献

Since the bovine spongiform encephalopathy crisis, there has been a growing interest for finding an alternative source of raw materials for gelatin production. Gelatin produced from fish processing by-products is a potential alternative to mammalian gelatin. Fish processing generates solid wastes that can be as high as 50-80% of the original raw material. These wastes are an excellent raw material for preparation of high protein foods. About 30% of the wastes consists of skin and bone with a high collagen content. Fish gelatin can be obtained by hydrolysis of collagen the principal protein found in skin and bone. Fish skin and bone gelatin can be prepared with bloom strength similar to that obtained from mammalian sources. Fish gelatin has numerous applications, particularly, in the food, pharmaceutical, and photographic industries due to its unique chemical and physical properties. This review presents how fish processing by-products can be utilized in the manufacture of gelatin. 相似文献

Fish wastes offer tremendous unexploited potential for value adding for such materials, collagen, gelatin, and hydrolysate. Additionally, fish waste may be suitable for the production of bioactive peptides that exhibit strong antihypertensive, antioxidative, and anticancer activities. This paper reviews the production of purified bioactive peptides from various fish waste protein hydrolysates via enzymatic hydrolysis after enzyme screening and optimization. The purification of bioactive peptides is carried out using ultra- and gel filtration as well as the RP-HPLC method. Purified peptide characterizations in terms of molecular weight, amino acid sequence, and composition are also provided, illustrating that peptides with low molecular weight and short amino acid sequences are more potent as bioactive peptides. Hence, further studies are encouraged to examine the bioactivity and bioavailability of protein peptides derived from fish wastes, especially those with anticancer characteristics. 相似文献

为从纺织的角度探索制革下脚料再利用的可能性,首先利用皮革专用粉碎机成功提取出长度为0.01~0.50 cm的超短真皮纤维,然后对其结构进行表征;同时测试纤维的吸湿性,并与羊毛和蚕丝蛋白质纤维进行比较。采用静电植绒方法制备真皮纤维麂皮绒产品。结果表明:超短真皮纤维呈束状存在,纤维之间的结合力大于单(束)纤维断裂强力,在达到饱和吸水量时,其吸湿性与羊毛相似,但好于蚕丝纤维,制成的真皮纤维麂皮绒产品性能接近超细纤维仿麂皮,适合用于装饰材料。 相似文献

Functional and bioactive properties of fish protein hydolysates and peptides: A comprehensive review
Global fish processing industries dispose of fish wastes that account for more than 60% of processed fish biomass. In lieu of environmental pollution and disposal problems, these wastes are used to produce fish silage, fishmeal and sauce. They are also utilized for the production of value added products such as proteins, hydrolysates, bioactive peptides, collagen and gelatin. Research on the production of fish protein hydroysates (FPHs) presently focuses on maximizing the industrial potential of fish wastes. Since bioactive peptides containing amino acids hold properties of great interest, this paper reviews current research on the functional and bioactive properties of FPHs with an additional focus on gaps between fish and other hydrolysates, as well as current and future trends for the productive utilization of FPHs. 相似文献
