Comparison of voluntary ethanol intake by two pairs of rat lines used as genetic models of anxiety. G.E. Da Silva, A. Ramos and R.N. Takahashi. Brazilian Journal of Medical and Biological Research, 37 (10): 1511, 2004.
Figure 1. Comparison of ethanol intake (A) and ethanol preference (B) between Floripa high (H) and low (L) lines. The concentration of the ethanol drinking solution was increased from 2 to 4%. Data are reported as g absolute ethanol ingested daily per kg body weight in panel A and as percent of ethanol compared to total fluid intake in panel B. Each point indicates the mean ± SEM for 9-10 animals per group. No strain effect was detected but females showed a greater ethanol intake and preference than males (P < 0.05, ANOVA).
