Abstract
Mitotic index and nuclear volume of the zona fasciculata externa have been studied using male and female Wistar rats weighing 20, 50, 100, 250 and 300 g. Adrenal weight of females was greater than of males. Early postnatal growth of adrenals was attained at the expense of intensity of mitotic division. With age mitotic division decreased but cell hypertrophy developed. Cell hypertrophy in females began at an early age and was more marked than in males.
摘要
使用体重为20、50、100、250和300克的雄性和雌性Wistar大鼠，研究了肾上腺束状带外层的有丝分裂指数和细胞核体积。雌性大鼠的肾上腺重量大于雄性。肾上腺在出生后的早期生长是以有丝分裂强度为代价实现的。随着年龄增长，有丝分裂减少，但细胞肥大开始发展。雌性大鼠的细胞肥大在早期就开始，且比雄性更明显。
