休眠期中华鳖消化器官中主要消化酶活性分布

为研究休眠期中华鳖中主要消化器官消化酶活性,将平均体重为672.25g的4龄鳖6只,处死后取其胃、肝、肠,采用生化方法测定其胃蛋白酶、脂肪酶和淀粉酶活性。结果表明,在中华鳖的胃、肝、前肠、中肠、后肠中均有胃蛋白酶、脂肪酶、淀粉酶。肠中蛋白酶活性由中肠、前肠、后肠递减,前肠与中肠的酶活性没有显著差异(P>0.05);肠中脂肪酶活性较胃、肝中的高;淀粉酶活性,肠中最高,胃中次之,肝脏中最低,但在肠的不同部位淀粉酶的活性没有显著差异(P>0.05)。

Study on Digestive Enzyme Activities of Hibernant Trionyx sinensis

This work investigated the digestive enzyme activities in the main digestive organs of Trionyx sinensis during hibernation.Six four-year-old turtles with the mean body weight of 672.25 g were sampled with stomach,liver and gut,and the activities of protease,lipase,amylase were studied.The results indicate that protease,lipase,amylase were found in stomach,liver and gut.The protease activities in midgut and foregut are higher than that in hindgut,no significant difference was found within midgut and foregut(P>0.05);The lipase activities in gut were highter than that in stomach and liver;the amylase activities in gut is higer than that in stomach and liver,no significant difference was found within the gut(P>0.05).
