摘要: 目的:研究蒿甲醚(Art)对血吸虫己糖激酶(HK)、磷酸葡萄糖异构酶(GPI)和磷酸果糖激酶(PFK)的影响。方法:感染血吸虫小鼠1次igArt100或300mgkg-1,并分别于24h和48h剖杀取虫。按生成NADPH和耗用NADH的方法测定上述3种酶活力。结果:感染鼠ig.Art300mgkg-1后24h,♀、虫体HK活力抑制率分别为33.3%和13.7%,GPI活力则分别抑制14.7%和17.5%,48h后,♀、虫体的GPI活力抑制率分别为46.2%和32.9%。但Art剂量为100或300mgkg-1时,给药后24h和48h的♀虫PFK抑制率分别为64.9%和71%,均明显高于虫的16.3%和54.2%。结论:PFK可能是Art作用于血吸虫糖酶解途径的靶酶之一。

Abstract: AIM:To study the effect of artemether(Art) on hexokinase(HK),glucose phosphate isomerase(GPI)and phosphofructokinase(PFK)of Schistosoma japonicum . METHODS:Mice infected with schistosome cercariae for 4-5 wk were treated ig with Art 100 or 300 mg·kg -1 and killed 24 h or 48 h after medication for collection of schistosomes.The activities of HK,GPI and PFK of the worms were determined by measuring the formation of NADPH or consumption of NAD...
