HE染色结果显示F组肝脏在2周即可见脂肪浸润，4周时出现轻度脂肪肝，8-12周出现中、重度脂肪肝；

HE staining revealed fatty infiltration of the liver at 2 weeks , mild fatty liver at 4 weeks and moderate to severe fatty liver at 8-12 weeks in group F.

重度脂肪肝与轻度脂肪肝之间PC、C、LN差异均有显著性（P<0.05～0.01），且阳性率较高。

The difference of PC ⅲ, C ⅳ, LN between the severe and early fatty liver cases was significant ( P < 0.05 ~ 0.01 ) . Positive rate of these indexes was higher in severe cases .

重度脂肪肝组血清ALT、AST、ALP水平较正常组、轻度脂肪肝组、中度脂肪肝组高（P<0.01）。

Serum ALT , AST , and ALP in high grade fatty liver group were significantly higher than those in control group , light grade fatty liver group and moderate grade fatty liver group ( P < 0.01 ) .

其中黑米皮高剂量组大鼠的肝和主动脉形态接近正常组，低剂量组的肝脏有轻度脂肪肝、主动脉无脂肪肝，而模型组大鼠肝和主动脉均形成了脂肪肝病症。

The morphology of liver and aortic in high dose group is close to that of normal group . There are mild fatty lesions in the liver with and no fatty lesions in the aorta in low dose group .
