The purpose was to determine the effect of a complex of factors of large cell (supraoptic, paraventricular) or small cell (arcuate) hypothalamic nuclei on adenohypophyseal proliferation and cytodifferentiation, manifested in body tissue culture. Experiments were staged on 80 hypophysectomized random bred albino male rats with a body mass of 200-230 g. The evaluation of cell types of adenocytes was performed at stages of implantation every 12h-26 days with the help of light optic, electron microscopic, histoautoradiographic, immunohistochemical and radioimmunoassay methods. Supraoptic and paraventricular nuclei were shown to provide for the stimulation of adenocytic proliferation. The factors of paraventricular nuclei enhanced secretion in somato-, mammo-, thyro- and corticotropocytes and created conditions for their secondary cytodifferentiation.
目的是确定下丘脑大细胞(视上核、室旁核)或小细胞(弓状核)复合体对腺垂体增殖和细胞分化的影响,这种影响在机体组织培养中表现出来。实验选用80只体重200 - 230克、随机繁殖的白化雄性大鼠,切除垂体后进行。借助光学显微镜、电子显微镜、组织放射自显影、免疫组织化学和放射免疫分析方法,在植入后的12小时至26天内每隔一段时间对腺细胞的细胞类型进行评估。结果显示,视上核和室旁核可刺激腺细胞增殖。室旁核的因子可增强生长激素细胞、催乳素细胞、促甲状腺激素细胞和促肾上腺皮质激素细胞的分泌,并为它们的二次细胞分化创造条件。
