摘要
应用放射核素１２５Ｉ－弓形虫感染孕１４天小白鼠，动态观察１２５Ｉ－弓形虫分布。结果证实，１２５Ｉ－弓形虫侵入孕鼠血液寄生于白细胞内，分布至脏器组织细胞胞浆内，少数在核内。孕鼠的单位重量组织的放射量由高到底顺序为肺、肝、脾、肾、心及脑，而胎鼠为头、肝、肺。胎鼠头／躯干放射量为１．３２∶５．９５。感染率胎盘为８５．８％，胎鼠为７６．８％（Ｐ＜０．０１）。临床跟踪５２例弓形虫感染孕妇，垂直传染胎儿２４例（４６．１５％），致不良妊娠结局１３例。提示临床对弓形虫感染孕妇应引起重视。
Female mice at 14 days gestation were infected with 125 I Tox G. Then the distribution of 125 I Tox.G, at different time was observed. The results showed that the 125 I Tox.Gondii intruded into blood of pregnant mice and stayed in WBC. It was mainly distributed into cellulous plasma of internal organ tissue, few in nucleus. The sequence of radiodensity from high to low is lung, liver, spleen, kidney, heart and brain in pregnant mice; while head, liver, lungs in fetal mice. The radiodensity ratio of fetal mice head/body is 1.32～5.95, the infection rates of placenta and fetal mice are 85.5% and 76 8%( P <0.01) respectively. In 52 cases of pregnant women infected with Tox. Gondii, 24 had infected foetus (46.15%) and 13 resulted in poor pregnancy, suggesting that attention should be given to pregnant women infected with Tox.Gondii.
