Effect of Early Sucrose Diet on Ethanol Preference and Behavior in Male and Female Wistar Rats
- 8 Downloads
The effect of adolescent sucrose diet on ethanol preference was studied in female and male Wistar rats. Our data show less pronounced ethanol preference in females. In males, pubertal exposure to sucrose was crucial for further ethanol preference, suggesting that cross-sensitization is more inherent to males than females, for whom the increased anxiety factor proved to be more significant. Finally, it was shown that in rats of both sexes habitual alcohol intake determins ethanol preference in the two-bottle test. Overall, our study demonstrates sex differences in ethanol preference as well as its anxiolytic properties.
