Abstract Male and female rats were administered ethanol (5% v/v) in a liquid diet for 18 weeks. Pair-fed control animals were fed the same diet except that dextrose was substituted isocalorically for ethanol. Normal controls received a commercial laboratory chow for the same duration. Results showed that, in females, chronic ingestion of an ethanol liquid diet significantly increased the number of muscarinic receptor binding sites compared to both control groups. In contrast, for males, there was no significant difference in the mean number of binding sites among the treatment groups. Furthermore, the mean maximum number of binding sites for males and females varied across brain areas. Males had a significantly greater number of receptor binding sites than females in the striatum, while females had a greater number in the cortex. It was suggested that the geuder differences observed in the present study could be mediated by hormonal effects on central muscarinic functioning.
