Zusammenfassung:To verify whether high-fat diet prepared from commercial diet plus chocolate, roasted peanuts and corn cookies induces hypercholesterolemia in mice and whether there is any hepatic involvement in this type of animal testing. Swiss mice received a high-fat diet for 15 and 30 days; plasma cholesterol, triglycerides and glucose rates were determined. Hepatic impairment was evaluated by histopathological analysis. Cholesterol levels increased 43% in animals treated with high-fat diet for 30 days. Further, histopathological analysis revealed that treatment of animals for 15 and 30 days produced hepatic steatosis and steatohepatitis, respectively. Experimental model is suitable for assessing the action of anti-hypercholesterolemia and the treatment of steatohepatitis. Keywords: hypercholesterolemia, fatty liver, high-fat diet. Verificar se a dieta hiperlipidica preparada a partir de racao comercial acrescida de chocolate, amendoim torrado e bolacha de maisena e capaz de induzir hipercolesterolemia em camundongos e se ha comprometimento hepatico neste modelo de experimentacao animal. Camundongos Swiss receberam a dieta hiperlipidica por 15 e 30 dias e apos isso, foram realizadas dosagens plasmaticas de colesterol, glicose e triglicerideos. O comprometimento hepatico foi avaliado por analises histopatologicas. Os niveis de colesterol aumentaram em 43% nos animais apos o tratamento com a dieta por 30 dias. Na analise do figado, contatou-se esteatose e esteato-hepatite nos animais tratados com a dieta por 15 e 30 dias, respectivamente. Este modelo experimental e adequado para a avaliacao da acao de farmacos anti-hipercolesterolemicos e que auxiliem no tratamento da esteato-hepatite. Palavras-chave: hipercolesterolemia, figado gorduroso, dieta hiperlipidica.
