Abstract:

To provide experimental and theoretical basis for the clinical application of Puerarin in acute alcohol poisoning, 30 Wistar rats were randomized into 3 groups as follows: (1) Group A (control) underwent normal sodium (N.S.) peritoneal injection (i.p.) and intragastric administration (i.g.); (2) Group B (alcohol) underwent an equivalent dosage of N.S. i.p. and 40% ethanol (8000 mg/kg. d).ig for 5 days; (3) Group C (Puerarin) underwent Puerarin 200 mg/kg. d. ip, and an equivalent dosage of ethanol for 5 days. The left lobes of livers were sampled, and the levels of MDA, SOD and GPX in plasma and liver homogenate were detected. The level of MDA in plasma and liver homogenate in the alcohol group was obviously higher than that in the control group (p<0.05, respectively), while that in the Puerarin group was significantly lower than in the alcohol group (p<0.05, respectively). The levels of SOD and GPX were opposite to that of MDA. Under a light microscope, the livers of the rats in the alcohol group showed unclear structure of hepatic lobules, stiffness of hepatic sinusoids, diffused lipid degeneration of hepatic cells, cellular swelling, and focal necrosis, while the structure remained clear in the Puerarin group. Under the electron microscope, lipid degeneration, cell organ decrease, enlargement of endoplasmic reticulum, reduced quantity of hepatins and swelling of mitochondria were observed in cells of the model group. However, the pathologistic changes were slight in the Puerarin group. In conclusion, Puerarin may have the function of inhibiting the oxidative stress induced by acute alcoholism.
