Postnatal stress in birds: a novel model of glucocorticoid programming of the hypothalamic-pituitary-adrenal axis.

abstract：:To probe the possible role of endogenous opiates in Sertoli cell proliferation during testicular development, the effect of interfering with beta-endorphin action either in vivo or in vitro was determined. The percent of Sertoli cells dividing was measured with quantitative autoradiography in [methyl 3H]-thymidine-exp...
