摘要 本文用实验方法对几种临床常用猪皮的主要盐能作了测定和比较,发现新鲜猪皮细菌污染率为9.8%。保存猪皮灭菌性能稳定;创面粘合力无显著改变。新鲜猪皮透水性值为37.84±9.37克/M^2/n。辐照皮透水性下降(P<0.8),GA.S,ARS透水性明显升高(P值均<<0.001)。对大鼠皮肤移植显示新鲜猪皮,辐照皮皮片内较早出现细胞侵润,移植后9天皮片腐离或开始窝离;而GAS,ARS在移植后12天还能保持皮片的组织学完整性。 Main properties of fresh and three various kinds of preserved pigskin have been compared in our experiment. Results indicated that the rates of bacterial contamination of fresh pigskin sterilized by conventional method was 9.8%, while no positive culture had been found in preserved pigskins. Tissue adherence values of preserved pigskin grafts were not lower or were a little lower than that of fresh pigskin graft at PhaseⅠ, and were higher or were a little higher at Phase Ⅱ(no statistical difference respectively) . Water permeability of fresh pigskin was 37.84+9.37 gm/m^2/h. Comparing witk this value, permeability of radiated pigskin slightly decreased, permeability of glutaraldehyde treated pigskin (GAS) and chlorhexidine-alcohol refrigerated pigskin (ARS) significantly increased (P<0.001 respectively) . Skin grafted on rats showed fresh, radiated heterografts infiltrated by host cellss on 5th post-graft days, and sloughed or began to slough on 9th post-graft days; while GAS. ARS heterografts were rarely invaded by host cellss, the general architectures of the grafts were still preserved up to 12th postgraft days.
