Effects of menstrual cycle phase on the reinforcing effects of phencyclidine (PCP) in rhesus monkeys.
Substantive evidence indicates that there are sex differences in the reinforcing effects of drugs, and gonadal steroid hormones, such as estrogen and progesterone, likely contribute to these differences. Among females, subjective effects of drugs differ as a function of menstrual cycle phase. The purpose of the present study was to compare oral self-administration of phencyclidine (PCP) in fema...
متن کاملThe effects of chronic cocaine self-administration on the menstrual cycle in rhesus monkeys.
Clinical studies suggest that cocaine disrupts reproductive function, but because cocaine abusers often abuse opiates and alcohol, it has been difficult to determine the contribution of cocaine alone. The effects of chronic cocaine self-administration on menstrual cycle duration and basal levels of progesterone were examined in eight female rhesus monkeys and compared with the effects of occasi...
متن کاملPhysical activity of adult female rhesus monkeys (Macaca mulatta) across the menstrual cycle.
Physical activity is an important physiological variable impacting on a number of systems in the body. In rodents and several species of domestic animals, levels of physical activity have been reported to vary across the estrous cycle; however, it is unclear whether such changes in activity occur in women and other primates across the menstrual cycle. To determine whether significant changes in...
متن کاملEffect of menstrual cycle on resting brain metabolism in female rhesus monkeys.
Little is known about the effects of the menstrual cycle on brain activity in primates. Here, we use 18F-fluorodeoxyglucose positron emission tomography to monitor changes in resting brain glucose metabolism across the menstrual cycle in female rhesus monkeys. Results showed greater activity in right lateral orbitofrontal cortex, a region involved in processing negatively valenced emotional sti...
متن کاملCirculating Inhibin A and Inhibin B in Normal Menstrual Cycle during Breeding Seasons of Japanese Monkeys
In order to clarify the endocrinological profiles of inhibins during normal menstrual cycles in Japanese monkeys, plasma concentrations of inhibin A and inhibin B were measured by enzymelinked immunosorbent assay. In addition, circulating gonadotropins and steroid hormones were measured. Blood samples were taken from four Japanese monkeys showing normal menstrual cycles. Plasma inhibin A remain...
