The adrenergic activity of the domestic hen was investigated. Administration of noradrenaline to laying hens at dose levels of 3-5, 7-0, and 14-0 microng/kg produced an increase in the magnal pressure, and a simultaneous decrease in the uterine pressure. Similar doses given to ovariectomized hens caused an inhibition of activity in both segments. Strips of tissues from the vagina and the uterovaginal junction of laying hens were exposed in vitro to noradrenaline at concentrations of 1-5 x 10(-6) and 2.9 x 10(-6) M. The vaginal strips reacted with a sharp increase in tension, while the uterovaginal preparations showed a more gradual and prolonged response. It is suggested that the beta inhibitory activity of the uterus and the alpha excitatory activity of the rest of the oviduct are involved in the regulation of ovum transport.
对家鸡的肾上腺素能活性进行了研究。以3 - 5、7 - 0和14 - 0微克/千克的剂量水平给产蛋母鸡注射去甲肾上腺素,会使血压升高,同时子宫压力降低。给切除卵巢的母鸡注射相同剂量会抑制两个部位的活性。将产蛋母鸡阴道和子宫阴道交界处的组织条在体外暴露于浓度为1 - 5×10(-6)和2.9×10(-6)M的去甲肾上腺素中。阴道条张力急剧增加,而子宫阴道制剂的反应则更为缓慢且持续时间更长。提示子宫的β抑制活性和输卵管其余部分的α兴奋活性参与了卵子运输的调节。
