本文采用十二烷基硫酸钠－聚丙烯酰胺凝胶电泳（ＳＤＳ－ＰＡＧＥ）对日本血吸虫肝门型童虫蛋白组分进行了分析，结果显示：１４ｄ肝门型雌雄童虫出现３３条蛋白区带，主带８条；２１ｄ肝门型雌雄童虫出现３４条蛋白区带，主带８条；２１ｄ雄性童虫出现３１条蛋白区带，主带７条。各组童虫与成虫比较，有２７～２８茶共同蛋白区带，提示日本血吸虫不同时期的肝门型童虫与成虫的蛋白组分在质与量方面虽然存在着某些差异，但总体上两者的蛋白组分有很大的相似性。 In this paper, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of Schistosoma japonicum hepatic stewarti protein components were analyzed, the results showed that: 14d hepatic portal male and female worms appear 33 protein regions There were 8 bands in the main band and 34 bands in the 21d male and female H. pylori. There were 8 bands in the main band and 31 bands in the 21 days. There were 27-28 common protein bands in each group, suggesting that although there are some differences in the quality and quantity of the protein components of Schistosoma japonicum and adult adults in different stages of Schistosoma japonicum, on the whole, There is a great similarity between the two protein components.
