Proliferative effect of aqueous extract of Hyptis fructicosa on liver regeneration after partial hepatectomy in rats

Efeito proliferativo do extrato aquoso da Hyptis fructicosa na regeneração hepática após hepatectomia parcial em ratos

PURPOSE: To evaluate the effect of aqueous extract of Hyptis fructicosa on hepatic regeneration after partial hepatectomy in rats. METHODS: Sixteen rats were divided in two groups: C (Control Group) and HF (Whose rats received aqueous extract of Hyptis fructicosa during 4 days using the dose of 100 mg/kg/day). On the consecutive day of this treatment, the animals of both groups underwent hepatectomy of about 67% of liver. Twenty four hours later, they were sacrificed, and the remaining mass of liver was removed and prepared to be studied through the PCNA immunohistochemical technique. RESULTS: The liver regeneration index of HF group was 53.56 ± 18.91%, while in C group was 21.12 ± 8.29% (p=0.0003). CONCLUSION: These results show that the administration of aqueous extract of Hyptis fructicosa using the dose of 100mg/kg/day increased the hepatocyte proliferation in the group HF.
