Figure 1. Changes in hepatic steatosis in rats after gavage administration of fat in the form of virgin olive oil.

Figure 1

Representative micrographs (×400 magnification) of livers from fasted animals (A) and 4 hours (B) and 8 hours (C) after receiving 5 ml of olive oil as a bolus. Liver sections (4 µm) were stained with hematoxylin and eosin and evaluated blindly. Morphometric changes in hepatic fat content (D) and analysis of triglyceride (E) and cholesterol (F) contents in rats where data are expressed as means ± SD for each group. Statistical analysis to evaluate dietary response was done using one-way ANOVA and the Mann-Whitney U test as post hoc test. a, P<0.05 vs control and b P<0.05 vs 4 h.
