objective to observe the effect of selenium on the acth positive cells in the pars distalis of pituitary of rat with colon mucosa cancer induced by azoxymethane(aom).

目的观察硒对致癌剂氧化偶氮甲烷（aom）所致大鼠结肠癌形成过程中，垂体远侧部acth阳性细胞的影响。

conclusion: the results suggested that the tsh positive cells in the pars distalis of pituitary of rat with colon mucosa cancer induced by aom might be related with the tumorigenesis.

结论：在大鼠实验性结肠癌形成过程中，脑垂体远侧部tsh细胞变化可能与机体肿瘤的发生有关。

it is considered morphologically proved that the substance p-like immunoreactive nerve fibers have effector role in the pars distalis of the dog.

本实验结果表明，犬腺垂体远侧部p物质样免疫反应神经纤维对腺细胞活动有直接调节作用。

the changes of acth cells in the pars distalis of rat pituitary during the healing process of experimental peritonitis were studied by immunocytochemical staining at electron microscopic level.

用免疫电镜方法，研究了在大鼠实验性腹膜炎自愈期间，垂体前叶acth细胞的变化。

objective: immunohistochemical changes of fsh positive cell in pars distalis of pituitary gland were observed in the course of inducing rat experimental gastric carcinoma.
