近年来的研究提示中枢神经系统对胸腺的功能可能有直接调控作用,曾有关于大鼠垂体中存在促进大鼠胸腺细胞增殖反应的活性因子的报道.本文对大鼠垂体和其他部位脑组组织提取液的促进胸腺细胞增殖反应的活性进行了初步研究. 取大鼠垂体,用Hank’s液匀浆制备2%提取液(20mg湿重组织/ml),作适当稀释后测定对胸腺 Recent studies have suggested that the central nervous system may directly regulate the function of the thymus. There have been reports on the presence of active factors that promote the proliferation of rat thymocytes in the pituitary gland of the rat. This article has studied the pituitary and other parts of the brain in rats. The activity of the extract to promote thymocyte proliferation was preliminary studied. The rat pituitary was harvested, and a 2% extract (20 mg wet tissue/ml) was prepared by homogenizing Hank’s solution. After proper dilution, the thymus was measured.
