体内或体外培养的血吸虫雄虫经一定浓度的吡喹酮作用后,移置含免疫血清的培养液中培养时,受损害的虫体体表有大量絮粒状物沉积,形成膜状包被,加重皮层的损害;在继续培养3天时,大部分或全部虫未见有明显恢复。若将虫移置含正常血清的培养液中培养时,则无此种现象,且大部虫的体表损害有不同程度的恢复。上述结果亦为扫描电镜的观察所证实。 In vivo or in vitro culture of schistosomiasis by a certain concentration of praziquantel role, the removal of immune serum containing culture medium, the damaged body of insect body surface deposition of a large number of flocs to form a film coating, Increased cortical damage; continued cultivation for 3 days, most or all of the worms no significant recovery. If the worm is displaced in culture medium containing normal serum, then no such phenomenon, and most of the body surface damage have different degrees of recovery. The above results were also confirmed by scanning electron microscopy.
