title: [Quantitative variations in the number and size of peritoneal mastocytes in the female rat during the normal sexual cycle, following ovariectomy and administration of estrogens].
abstract: Female rat peritoneal mast cells were found more numerous and of more reduced sizes in metestrus and diestrus than in proestrus and especially estrus where a partial degranulation took place. Ovariectomy caused an important decrease in the number and size of mast cells. A regular treatment of spayed animals by 17 beta estradiol partly inhibited these effects.
