The effect of the aqueous extract Peumus boldus on the proliferation of hepatocytes and liver function in rats submitted to expanded hepatectomy

PURPOSE: To assess the effect of aqueous extract of Peumus Boldus (AEPB) on the liver proliferative response after parcial hepatectomy of 70% (PH) in rodents.

METHODS: Twenty Wistar rats were divided in two groups: AEPB100 (whose rats received 100mg/Kg of AEPB, once a day, orally, in 4 days prior to the first surgical procedure) and Vehicle (whose rats were treated similarly with distilled water). Both groups underwent PH. After 24 hours the remaining livers were removed for studying the proliferation of hepatocytes by Ki-67 and 2mL of blood were collected for serological assessment: cholesterol, glucose, triglycerides, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, and total, direct and indirect bilirubin. All data were analyzed by Gaussian distribution. Statistically significant differences between mean values were analyzed using T Student’s test. Non-Gaussian data were analyzed using Mann-Whitney’s test.

RESULTS: The liver of all these rats presented positive staining of Ki-67, indicating liver proliferation. Laboratory results showed no significant difference in serum values between the analyzed groups. The analysis of Ki-67 was significantly more positive in AEPB100 group than in Vehicle group.

CONCLUSION: Aqueous extract of Peumus Boldus acute administration exerts significant positive effect on liver regeneration after 24h in rats that underwent parcial hepatectomy, while maintaining unchanged hepatic function.
