本文报道肠系膜末梢血管阻塞对成虫寄居的影响。24只实验兔经手术结扎或10％AgNO_3液处理肠系膜末梢血管造成远端栓塞,于2～14d后剖检,发现成虫已全部转移至未经处理的(未结扎)血管内重新寄居,对照兔则无变化。结果提示,产卵通道阻塞和局部循环障碍可致成虫移位。慢性病人肠活检活卵率低的机制,可能与此现象有关。
This article reports the effects of mesenteric peripheral vascular occlusion on adult resident. Twenty-four rabbits were surgically ligated or treated with 10% AgNO 3 solution for distal embolization of the mesenteric vessels. Post-mortem was performed 2 to 14 days later, and all the adults were transferred to the untreated (non-ligated) vessels for re-establishment. Control rabbits No change. The results suggest that ovipositional obstruction and local circulatory disturbance can cause adult translocation. Chronic patients with intestinal biopsy live low rate of the mechanism may be related to this phenomenon.
