关于从宿主肠内驱除寄生虫的机理,近来已有很多迹象证明,巴西日本圆线虫的驱出大部分是由于肥大细胞释出的生物原胺引起的局部过敏性。伴随过敏性的组织病理变化使抗体能透过肠壁而产生“自愈”现象。曾有报道用抗组织胺和抗5—羟基色胺药物治疗动物,能延长旋毛虫的肠内期,用抗淋巴血清治疗,能使动物感染后延长旋毛虫病的肠内期达50天。本文作者观察了组织胺释放 With regard to the mechanism of expelling parasites from the host intestine, there have been many indications recently that the predation by C. elegans of Brazil is largely due to the local allergies caused by the biogenic original amines released by mast cells. Accompanied by allergic histopathological changes so that antibodies can penetrate the intestinal wall and produce “self-healing” phenomenon. It has been reported that treatment of animals with antihistamine and anti-5-hydroxytryptamine drugs prolongs the intestinal phase of Trichinella and prolongs the intestinal tract of Trichinellosis for up to 50 days after infection with an anti-lymphoid serum. The authors observed histamine release
