Resumo: | Objetivo: Este estudo foi realizado com o objetivo de verificar o efeito do extrato aquoso da Hyptis pectinata na regeneração hepática bem como nos níveis das enzimas séricas (AST, ALT e γ-GT) após hepatectomia parcial de 67% em ratos. Métodos: AST, ALT e γ-GT, foram determinadas pelo método cinético utilizando um espectrofotômetro (Modelo E2250- CELM). A regeneração hepática foi avaliada por imunohistoquímica (PCNA). Resultados: O pré-tratamento oral de 100 mg/ kg foi realizado durante 4 dias e causou aumento na regeneração hepática O pré-tratamento oral com 200 mg/kg diminuiu significativamente os níveis de AST quando comparado com o grupo submetido ao pré-tratamento com água destilada. As demais enzimas avaliadas não apresentaram diferenças quando comparadas entre os grupos estudados. Conclusão: O presente estudo mostra que o extrato aquoso da Hyptis pectinata, numa concentração de 100 mg/kg possui alguma atividade biológica estimulando a regeneração hepática e causando também um leve efeito hepatoprotetor numa concentração de 200 mg/kg. _________________________________________________________________________________________ ABSTRACT: Purpose: This study was carried out to assess the effects of the aqueous extract of Hyptis pectinata leaves on liver regeneration and on serum enzymes (AST, ALT and γ-GT) after 67% partial hepatectomy in rats. Methods: AST, ALT and γ-GT, were determined by conventional procedures using a spectrophotometer (Model E2250-CELM). Liver regeneration was evaluated by immunohistochemical staining for proliferating cell nuclear antigen (PCNA). Results:Oral pretreatment during 4 days at 100 mg/kg increased liver regeneration index. At 200 mg/kg, AST level was statistically decreased in comparison to the group submited to distilled water administration. The other enzymes assessed disclosed no difference when all groups were compared. Conclusion: The present study shows that the aqueous extract of Hyptis pectinata leaves contains some biological active principles that stimulate liver regeneration at 100 mg/kg and cause slight hepatic protection at 200 mg/kg. |
