本文叙述了在体外用物理方法刺激大量尾蚴产生头腺分泌、发育到童虫以及变化中的生化差异。分析步骤:制备每毫升1,000条尾蚴的混悬液,在室温和一定的pH条件下,通过6,000～8,000g离心,获得压积的尾蚴和含有类童虫的幼虫的块状物,再经超声处理获得尾蚴与童虫抽提物,按Stirewalt描述的

This article describes in vitro physical methods to stimulate a large number of cercariae produce the secretion of the gonads, the development of schistosomiasis and changes in the biochemical differences. Assay procedure: A suspension of 1,000 cercariae per milliliter is prepared and centrifuged at 6,000 to 8,000 g at room temperature under certain pH to obtain a mass of cercariae and larvae containing caterpillars, which are then sonicated Processed to obtain cercariae and juvenile extract, as described by Stirewalt
