By morphometric methods the quantitative changes of cell, cytoplasm, nucleus, nucleolus and also of the contents of secretes from the neurosecreting cells of the N.S.O. (Pars parvocellularis and Pars magnocellularis) and N.P.V. from unmilked and milked cows was investigated. This single parameters change in N.S.O. and N.P.V. approximately in the same rhythm. The nucleus-plasma-relation is only unessential influenced. The cytoplasm of the neurosecreting cells of the N.P.V. from unmilked and milked cows is greater ca 6 once, than the nucleus of this. The cytoplasm of the neurosecreting cells of the N.S.O. is greater ca 5 once. A maximal increase of the size of the single parameters and so the greatest activity were observed in the neurosecreting cells of the N.S.O. and N.P.V. of cows, which were prepared 15 min after milking. 60 min after milking of the cows they reach the initial value. The reaction to the milking stimulus is maximal 3 once greater in the neurosecreting cells of the N.P.V. than in the N.S.O. To the same time after the milking stimulus the contents of secretes is maximal diminished about 10 once in the N.P.V. and about 8 once in the N.S.O. The conception that in the N.P.V. the hormon oxytocin is synthetized, is anew supported.
通过形态测量学方法，研究了未挤奶和已挤奶牛的视上核（小细胞部和大细胞部）和室旁核神经分泌细胞的细胞、细胞质、细胞核、核仁以及分泌物含量的定量变化。视上核和室旁核的这些单一参数变化节奏大致相同。核质关系仅受到非本质影响。未挤奶和已挤奶牛室旁核神经分泌细胞的细胞质大约比其细胞核大6倍。视上核神经分泌细胞的细胞质大约大5倍。在挤奶后15分钟制备的奶牛的视上核和室旁核神经分泌细胞中，观察到单一参数大小的最大增加，即最大活性。在奶牛挤奶60分钟后，它们恢复到初始值。室旁核神经分泌细胞对挤奶刺激的反应比视上核大3倍。同时，在挤奶刺激后，室旁核分泌物含量最大减少约10倍，视上核约减少8倍。室旁核中合成激素催产素这一观点再次得到支持。
