辐照氟银猪皮的实验研究

报道辐照氟银猪皮的制备、实验检测（弹性、创面粘附力和透水性测定，含银量测定）组织学检查细菌检测及抑菌试验研究，结果表明：辐照氟银猪皮除延伸度低于未辐照猪皮外，其撕裂强度、创面粘合力和透水性均与未辐照猪皮相似。组织学检查示：辐照氟银猪皮组织结构完整，表皮细胞部分空泡形成。组织细菌检测证明其无菌生长，达到无菌要求。抑菌试验证明对金黄色葡萄球菌、绿脓杆菌、大肠杆菌、变形杆菌、克雷伯氏菌均有极强的抑菌作用

Experimental study of radiated pig skin incorporated with nofloxacin and silver

This paper presents the preparation and experimental use of radiated pigskin incorporated with nofloxacin and silver(RPSNS).The results show that tensile strength,tissue adherence and water-vaporu permeability of RPSNS are not significantly different from that of pigskin without radiation.The histological structure of RPSNS is essentially normal.However,some of the epidermal cells present vesicles.No positive cultrue is found in RPSNS and radiated pigskin,while the rate of positive bacterial culture of pigskin sterilized by Bromogeramin is 10%.RPSNS can effectively inhibit Staphy.aureus,Ps aeruginosa,E.coli,Proteus and Klebsiella.The results indicate that RPSNS is a kind of sterile biological dressing with strong anti-bacterial effect.
