Previous research from this laboratory demonstrated that male outbred rats (Long-Evans) can be trained to prefer ethanol (10% v/v) over water during 30-min home-cage sessions and that higher ethanol concentrations (18-32% v/v) can serve as a reinforcer under various operant schedules. Further, we have shown that two neurosteroids, dehydroepiandrosterone (DHEA) and pregnanolone, can readily decrease ethanol self-administration in males. The present study used the same procedures in an attempt to systematically replicate the previous findings in female outbred rats. Rats were first trained to self-administer ethanol in the home cage using a saccharin-fading procedure. Subsequently, a two-bottle preference test was initiated by substituting different ethanol concentrations after subjects reliably consumed 10% ethanol alone. Water was always available during this phase. Next, subjects were transitioned to a fixed-ratio 10 (FR-10) schedule of reinforcement with 0.1 mL of ethanol (18% v/v) serving as the reinforcer so that a concentration-effect curve could be established. Upon completion, subjects were transitioned to an FR-10 FR-20 multiple schedule of ethanol (32% v/v) and food reinforcement to determine whether noncontingent ethanol, DHEA, and pregnanolone could selectively decrease ethanol intake. Not surprisingly, female subjects preferentially consumed ethanol over water at concentrations of 3.2-18% (v/v) during the home-cage procedure, and significantly increased the mean dose of ethanol consumed and blood ethanol concentration (BEC). Similarly, increasing concentrations under an FR-10 schedule significantly increased the dose of ethanol presented and BEC compared to control (water). Finally, under the multiple schedule, noncontingent injections of ethanol (0.32-1.8 g/kg), DHEA (10-100 mg/kg), and pregnanolone (1.8-32 mg/kg) dose-dependently decreased food- and ethanol-maintained responding and the dose of ethanol presented. BEC was significantly decreased by the neurosteroids, but increased by ethanol due to its noncontingent administration. Together, these data replicate only a subset of the data previously obtained in males, suggesting there are sex differences particularly with respect to the effects of DHEA and pregnanolone.
