Abstract

Diestrous rats were treated with an injection of luteinizing hormone (LH), and their ovaries were examined for mast cell number and stage of degranulation at 2 and 4 hr post-injection. LH tripled the number of medullary mast cells at 2 hr. The source or origin of the additional mast cells is unknown. Comparison of the present results with other studies of rat ovarian mast cell dynamics suggests the occurrence of a reduction in mast cell number in early to mid-proestrus followed by an LH-induced increase in late proestrus.

摘要

对处于间情期的大鼠注射促黄体生成素（LH），并在注射后2小时和4小时检查其卵巢中的肥大细胞数量和脱颗粒阶段。LH使注射后2小时髓质肥大细胞数量增加两倍。额外肥大细胞的来源尚不清楚。将目前的结果与其他关于大鼠卵巢肥大细胞动态变化的研究进行比较，结果表明在发情前期早期到中期肥大细胞数量减少，随后在发情后期LH诱导肥大细胞数量增加。
