Abstract:
:The peripubertal period in the female rat is the time when the stimulatory effects of opioids on prolactin (PRL) secretion develop. In the adult rat, the administration of chronic high-dose morphine has been shown to attenuate the ability of opiates to stimulate PRL secretion. One function of PRL in adult virgin rats is the induction of maternal behavior. The present study examined whether chronic high-dose morphine exposure during the peripubertal period alters PRL-mediated induction of maternal behavior in adult female rats. Two groups of juvenile female rats were administered increasing doses of morphine or vehicle (s.c.) from age 30 to 50 days. As adults, these females either remained intact, or were ovariectomized and treated with a PRL-dependent, steroid hormone regimen that stimulates a rapid onset of maternal behavior. All females were then exposed daily to rat foster pups to determine whether peripubertal morphine exposure affected their latencies to induce maternal behavior. Morphine treatment resulted in a delay in vaginal opening and a temporary reduction in the rate of weight gain; however, the rate of onset of maternal behavior was unaffected by peripubertal morphine treatment. Thus, chronic morphine exposure in the pubertal female did not impact the expression of pup-induced maternal care.
