METHODS 3-methoxy-7α-methylestra-1,3,5(10)-trien-17β-ol was reducted with lithium and ammonia,then the intermediate was hydrolyzed in oxalic acid and reacted with malonic acid to get 3,3-dimethoxo-7α-methylestra-5(10)-en-17-ol(compound 4),which was oxidated by pyridium bichromate ,reacted with acetylene,and hydrolyzed in oxalic acid again to get the product tibolone.

方法以3-甲氧基-7α-甲基雌甾-1，3，5(10)-三烯-17β-羟基为起始原料经锂胺还原、草酸水解、缩酮化得3，3-二甲氧基-7α-甲基雌甾-5(10)-烯-17β-羟基(化合物4)，然后用温和的氧化剂重铬酸吡啶盐氧化、炔化、再水解得目的产物。

Objective To explore the presence of biliverdin reductase activity in adult worms of Schistosoma japonicum in vitro.

目的 探讨日本血吸虫是否含有能降解胆绿素的胆绿素还原酶(biliverdinreductase，BR)及其活性。

When the colon to push stool when biliverdin after reduction, but also into bilirubin, when yellow stool.

当大便推送到结肠时，胆绿素经过还原作用，又转变为胆红素，这时大便呈黄色。

When the colon to push stool when biliverdin reduction has been transformed into bilirubin, yellow stools.

当大便推送到结肠时，胆绿素经过还原作用又转变为胆红素，大便呈黄色。

When the stool when pushed to the colon, after biliverdin reduction, but also into bilirubin, when yellow stool.

Because of the small intestine when the upper part of the role of bilirubin and bilirubin, it was yellow-green; to colon when biliverdin reduced to bilirubin, and yellow.

在小肠上部时由于胆红素及胆红素的作用，故呈黄绿色；到结肠时胆绿素还原成胆红素，而呈黄色。

Heme oxygenase catalyze the rate-limiting step in the degradation of heme to yield equimolar amounts of biliverdin, carbon monoxide , and iron.

亚铁血红素氧化酶是将亚铁血红素降解为胆绿素、铁和一氧化碳的限速酶，胆绿素则在胆绿素还原酶的作用下转变为胆红素。
