- Conclusion Selenium can promote the function of the ACTH positive cells in the pars distalis of rat pituitary with colon mucosa cancer induced by AOM.
- 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).
摘要 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。
- Objective: To observe the effect of selenium on the TSH positive cells in the pituitary pars distalis of rat with colon mucosa cancer induced by azoxymethane (AOM).
- There were no sands in the content of parts muscularis ventraculi The liver were devided into two lobes. The right and left lobe had portahepatis. The left lobes were connected with ansa distalis of duodenum by hepatic tract and pancreas tracts.
- Thyotrophs are localized in proximal pas distalis (PPD) of the pituitary gland.Immunoreactivity of TG is found within the thyroid29follicle lumina and cytoplasm of follicle epithelial cells.
- Conclusion: With the number of FSH positive cells in pars distalis decreases, the function of synthesizing and secreting diminshed during the rat experimental gastric carcinoma development.
