| Abstract |
Using an in vitro perifusion system, the present study investigated the possibility that alterations in catecholamine and luteinizing hormone-releasing hormone (LHRH) secretion from the male rat mediobasal hypothalamus are present during the period of middle-age. The results indicate that, while tissue concentrations and baseline secretion of norepinephrine, dopamine and LHRH were similar between age groups, the patterns of dopamine and LHRH release in response to a series of depolarizing stimuli was different in the older animals. After all challenges, dopamine concentrations in the perifusate declined much more sharply for the middle-aged group, a finding that may be associated with a decrease with age in the pool of transmitter available for ready release.
