METHOD: Sperm from 20 infertility patients was liquefied by trypsase and injected into uterus ( group A). Only one patient was successfully pregnant. The rest 19 patients received sperm washing technique ( group B). 方法:采用胰蛋白酶液化不育症20例精液宫腔注入(A组),其中未受孕19例精液,再采用洗涤法后宫腔注入(B组),观察受孕。
The optimal pH for the toxin was 6-8 and resistant to trypsase. 毒素活性的最适pH为6&8,对胰酶有抗性;
Objective To investigate the possibility for acellular dermis ( AD) prepared by trypsase and repeated freeze thaw cycles to be an ideal dermal substitute for construction of composite skin. 目的:观察胰蛋白酶及冻融法制备的脱细胞真皮能否为构建人工复合皮提供一种理想的真皮替代物。
