With mathematical-statistical methods the reaction of the Nucleus supraopticus (N.S.O.) and Nucleus paraventricularis (N.P.V.) were investigated before and after the milking of the cows. The frequency-distributions of the tests of the nuclear volumes in the N.S.O. and N.P.V. show an increase of the mean values of the nuclear volumes from the unmilked cows to those studied 15 minutes after the milking. The mean values of the nuclei volumes of the cows studied 60 minutes after the milking fall off, but they are higher than the values of the unmilked cows. The results of the histological-histochemical investigations mainly coincided with the results obtained by caryometry. It is discussed, that the changes in the nuclear bolumes show an increased protein synthesis and that -- combined with the release of oxytocin -- the milk stimulus caused a secretory synthesis in the neurosecretory cells, mainly in the N.P.V.
采用数理统计方法，对奶牛挤奶前后视上核（N.S.O.）和室旁核（N.P.V.）的反应进行了研究。对视上核和室旁核细胞核体积检测的频率分布显示，从未挤奶的奶牛到挤奶后15分钟所研究的奶牛，细胞核体积的平均值有所增加。挤奶后60分钟所研究奶牛的细胞核体积平均值下降，但其仍高于未挤奶奶牛的数值。组织学 - 组织化学研究结果与细胞核测量法所获结果基本一致。讨论认为，细胞核体积的变化表明蛋白质合成增加，并且——与催产素的释放相结合——乳汁刺激在神经分泌细胞中引发了分泌性合成，主要是在室旁核中。
