title: [The effect of naloxone and leu-enkephalin on the atretic changes in the ovarian follicles of hypophysectomized rats].
abstract: In 21--23-day-old female Wistar rats with atresia of the ovarian follicles, naloxone administration increased the number of 100-200 mcm follicles with atresia-induced changes, whereas enkephaline prevented the effect. Role of the brain opioid system in the above phenomenon, is discussed.
