摘 要：
本试验以昆明种小白鼠的第三对乳腺的形态、乳腺泡形成度及乳腺面积为主要依据,结合其体重和相关的主要内分泌器官的重量(垂体前叶、肾上腺、卵巢),探讨了处女鼠不同日龄和繁殖鼠不同时期乳腺的生长发育规律。结果表明;未经产昆明种小白鼠的乳腺在30日龄前以乳腺导管的生长发育为主,未发现腺泡的发育,40日龄至70日龄间乳腺导管及乳腺泡均有所生长发育,在80日龄达到顶峰,之后腺泡有所退化;妊娠后乳腺发育旺盛,特别是妊娠末期乳腺腺泡及乳腺导管都有显著的增长,乳腺进入预期的发育状态,而哺乳结束后则乳腺开始退化。

摘 要：
In this experiment we studied(1)the formation of the third twin m- ammary gland、(2)Mammary rating and(3)the mammary gland area in Kun Ming Mice.This experiment also studied the relationship between tot- al weight of each mouse and the weight of each of the main endocrine org- ans(anterior pituitary、adrenals、ovaries.We looked for the growth regula- rity of the mammary gland in virgin mice and breeding mice at 10 days i- ntervals These results showed that within 30 days the mammary gland ductus in virgin Kun Ming Mice grew very well.However in the same period there was no growth of the mammary gland alveolars.For groups of both virgan mice and breeding mice between 40 to 70 days,there was some growth in the mammary gland ductus and alveolars Growth reached a peak at 80 days. Then the growth of alveolars began to decrease to some extent There was great growth of the mammary glands after pregnacy,especi- ally in the last phase.0The alveolars and the ductus all showed notable gr- owth。The mammary gland in size after nursing。
