The pineal glands of pregnant and nursing sows were studied by light and electron microscopy. Similar structural changes in the pineal gland during pregnancy and lactation were noted as follows: a proliferation of glial cells concurrent with a decrease in the number of pinealocytes, a relative increase in the number of pinealocytes with cytoplasmic accumulation of dense bodies, and an increase in number of presumptive microglia. It appears that pregnancy and lactation exert a complex influence on pineal function, with a predominantly stimulating effect.
通过光学显微镜和电子显微镜对妊娠和哺乳母猪的松果体进行了研究。观察到妊娠和哺乳期间松果体有相似的结构变化，如下所示：神经胶质细胞增殖，同时松果体细胞数量减少；松果体细胞数量相对增加，细胞质中致密体聚集；假定的小胶质细胞数量增加。看来妊娠和哺乳对松果体功能产生复杂影响，主要是刺激作用。
