[The influence of @entity353 on the reproductive function of the female XXXX : changes in the estrous cycle and hypothalamo-pituitary-ovarian function during feed restriction and subsequent refeeding period].

@entity43 @entity353 @entity1420 @entity1640 @entity1218 @entity1176 @entity35
Twelve-week-old female SD @entity35 were restricted to an 8 g/day feed intake for 2 months followed by feeding ad libitum for 3 weeks. Feed restriction resulted in @entity353 and constant diestrous. A persistent increase in the hypothalamic @entity1176 content was observed during the underfed period. Serum LH and PRL levels dropped throughout the period but the initial reduction in the serum FSH level was observed on the 60th day. The reductions in the pituitary content of these hormones were observed on the 30th day. The decrease in the serum and ovarian E2 levels were detected on the 14th day. Anterior pituitary showed a significant response to @entity1176 + @entity1218 during the course, and the relative increases in LH, FSH and PRL were greater than those in the pretreatment @entity35 . In the course of refeeding, the body weight returned to the control level and regular estrous cycles were reestablished on the 15th and 21st day, respectively. @entity1640 @entity1176 content returned to the control level on the 16th day. The changes in the @entity43 were prompt rebound rises in serum FSH and PRL levels and pituitary FSH content, delayed restoration of serum and pituitary LH levels and serum and ovarian E2 levels, and a marked increase in the serum and ovarian @entity1420 levels on the 16th day. The relative increases in FSH and PRL after @entity1176 + @entity1218 injection were smaller than those in the underfed period.(ABSTRACT TRUNCATED AT 250 WORDS)
