Effects of long-term ethanol consumption on jejunal lipase and disaccharidase activities in male and female rats

Figure 1 Changes in the ethanol concentrations of liquid diet (A) and blood (B) after ethanol feeding. Data are expressed as mean±SE (n = 10).

Figure 2 Histological examinations of specimens from the liver in each group. Livers from group MC (A), ME (B), FC (C), and FE (D) are shown. Sections of the liver from rats fed with control diet for 12 wk show normal histology with no evidence of pathologic change (A and C). Fat accumulation in female ethanol-fed rats was panlobular (D), but it was seen in pericentral areas in male ethanol-fed rats (B). (H&E stain, magnification: ×200).

Figure 3 Representative Western blot of hepatic microsomal protein showing the induction of CYP2E1 due to chronic ethanol administration both in male and in female rats. Each lane represents an individual rat liver. The indicated apparent molecular masses of CYP2E1 and actin (internal control) were 54 and 43 ku, respectively.
