The fine structure of the fetal rat thyroid and parathyroid glands was studied at term and during prolonged gestation, which was induced by subcutaneous injections of progesterone to the mothers from gestational days 20 through 24. At term, the follicular and parafollicular cells of the thyroid as well as cells of the parathyroid exhibited well developed cytoplasmic organelles. Morphological changes were not detected in either of the endocrine glands during prolonged gestation. The results are discussed in relationship to 1) thyroid follicular cell activity during stress and 2) the function of thyroid parafollicular and parathyroid cells in calcium homeostasis.
研究了足月及延长妊娠期大鼠胎儿甲状腺和甲状旁腺的精细结构，延长妊娠期是通过在妊娠第20至24天给母鼠皮下注射孕酮诱导的。足月时，甲状腺的滤泡细胞和滤泡旁细胞以及甲状旁腺细胞均表现出发育良好的细胞质细胞器。在延长妊娠期，两个内分泌腺均未检测到形态学变化。结合以下两方面对结果进行了讨论：1）应激期间甲状腺滤泡细胞的活性；2）甲状腺滤泡旁细胞和甲状旁腺细胞在钙稳态中的功能。
