【摘要】 用链酶亲和素-生物素过氧化物酶复合物(SABC)免疫组织化学方法,使用抑制素α亚基单克隆抗体对注射抑制素α片段及抑制素粗提物后的去卵巢大鼠的下丘脑和垂体进行了免疫组织化学定位。结果表明,在下丘脑与垂体存在抑制素α亚基单克隆抗体的特异性阳性反应位点,并存在剂量与时间上的依赖关系,说明抑制素α亚基可以通过血脑屏障到达下丘脑和垂体,为探讨抑制素α亚基在血脑屏障的转运机制提供了形态学上的依据。更多还原

【Abstract】 Using the Strept Avidin Biotin-peroxidase Complex(SABC) immunohistochemical staining technique, immuno- histochemical localization of inhibin á subunit of rat hypothalamus and pituitary with inhibin á subunit monoclonal antibody was performed at different times post the injection. The sexually matured ovari-ectomized rats were injected with inhibin á subunit crude abstracts and different levels of inhibin á subunit fragments. The results showed that positive reaction sites in dose and time dependant ways were detected in the hypothalamus and pituitary, suggesting that inhibin á subunit could pass through the blood-brain barrier arriving at hypothalamus and pituitary. It provided new morphological basis for the research field of a passage mechanism of the subunit through blood-brain barrier.更多还原
