Allografts are in constant demand, not only for burn victims, but also for all open wounds as "biological dressings". Tissue quality and security are two of the major concerns of Tissue Banks. There are limited studies published. There has been extensive discussion on the subject of preservation methods for cadaver skin. Most literature available comes from clinical reports. In this research, the authors compared 85% glycerolized non irradiated skin allografts with three glycerolized irradiated skin allografts (using different glycerol concentrations 50%, 70% and 85%). The evaluation of allograft quality was done by measuring physical and biological properties of such prepared human tissue grafts. In the histological structure evaluation changes were minimal and did not alter the skin structure. The clinical function of their behavior as temporal dressings was tested. They proved to have similar capabilities for improving granulating tissue and contributing to wound beds closure (Hickerson et al. (1994) [1]).
同种异体移植物的需求一直存在,不仅用于烧伤患者,还作为“生物敷料”用于所有开放性伤口。组织质量和安全性是组织库的两大主要关注点。已发表的相关研究有限。关于尸体皮肤保存方法的主题已有广泛讨论。现有大多数文献来自临床报告。在本研究中,作者将85%甘油化未辐照的同种异体皮肤移植物与三种甘油化辐照的同种异体皮肤移植物(使用不同甘油浓度50%、70%和85%)进行了比较。通过测量此类制备的人体组织移植物的物理和生物学特性来评估同种异体移植物的质量。在组织结构评估中,变化极小,未改变皮肤结构。测试了它们作为临时敷料的临床功能。结果证明,它们在促进肉芽组织生长和促进伤口床闭合方面具有相似的能力(希克森等人,(1994年)[1])。
