Resumo

Objetivo: Desenvolver um modelo de dieta rica em gordura (DRG) que sozinho não resultou em doença hepática gordurosa não alcoólica (DHGNA), permitindo estudar a associação de comorbidades com o modelo de dieta rica em gordura. Material e métodos: Os ratos foram divididos em 2 grupos: dieta padrão e dieta rica em gordura, cada grupo com 8 animais. Os ratos foram submetidos à análise dos seguintes parâmetros no tecido hepático: dosagem de malondialdeído (MDA), glutationa (GSH) e atividade da mieloperoxidase (MPO). As amostras de fígado também foram avaliadas histopatologicamente quanto aos níveis séricos de alanina aminotransferase (ALT), aspartato aminotransferase (AST), albumina (ALB), fosfatase alcalina (FAL), ácido úrico e colesterol total (TC), cálcio (CA), ureia e HDL. Resultados: Mostraram que houve diferença significativa em MDA, GSH, colesterol total (CT), ALT, ALB, ácido úrico (AU), cálcio (CA) e HDL. A avaliação histopatológica apresentou escore baixo, insuficiente para a classificação da DHGNA. Conclusão: Este estudo demonstrou que o modelo de dieta rica em gordura não causou DHGNA. Esse achado permite utilizar a dieta hiperlipídica caracterizada neste estudo para investigar as possíveis alterações hepaticas causadas por outras comorbidades.
