ABSTRACT

PURPOSE:

To evaluate the alterations on plasmatic lipids levels among rats submitted to total splenectomy isolated or combined with splenic autotransplant receiving standard chow during the postoperative period.

METHODS:

Thirty Wistar rats were divided into three groups control (C) - sham-operated, total splenectomy - isolated (TS) or combined with splenic autotransplantation (SA). Since the postoperative period, all animals received standard rat chow manipulated in accordance to the American Institute of Nutrition Rodents Diets (1993). The plasmatic levels of total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), very-low-density lipoprotein (VLDL), and glucose (GLUC) were analyzed before the surgical procedure and after 6 and 12 weeks.

RESULTS:

All the animals presented significant increase of TG and VLDL levels. In relation to the other parameters there was no difference among the weeks 0 and 12 in the animals of group C. In TS group significant increase was observed in TC and GLUC levels during the experiment. In SA group TC, HDL, and GLUC levels remained unaffected while HDL levels increased.

CONCLUSION:

Our findings suggest that isolated total splenectomy alters lipids metabolism in rats fed with standard chow and splenic autotransplantation is effective in restoring its control.
RESUMO

OBJETIVO:

Avaliar as alterações nos níveis de lipídios plasmáticos em ratos submetidos a esplenectomia total isolada ou combinada com auto-implante esplênico, recebendo dieta padrão no período pós-operatório.

MÉTODOS:

Trinta ratos Wistar foram distribuídos em três grupos controle (C) - operação simulada, esplenectomia total isolada (ET) ou combinada com auto-implante esplênico (AE). A partir do período pós-operatório, todos os animais receberam ração padrão, manipulada segundo o American Institute of Nutrition (1993). Os níveis plasmáticos de colesterol total (CT), triglicerídeos (TG), lipoproteína de alta densidade (HDL), lipoproteína de baixa densidade (LDL), lipoproteína de muito baixa densidade (VLDL) e glicose (GLIC) foram analisados antes do procedimento e após 6 e 12 semanas.

RESULTADOS:

Todos os animais apresentaram aumento de TG e VLDL. Em relação aos demais parâmetros, não ocorreu diferença entre as semanas 0 e 12 nos animais do grupo C. No grupo ET, observou-se aumento de CT e GLIC durante o experimento. No grupo AE, os níveis de CT, HDL e GLIC permaneceram inalterados enquanto os níveis de HDL se elevaram.

CONCLUSÃO:

Nossos achados sugerem que a esplenectomia total isolada altera o metabolismo lipídico em ratos alimentados com ração padrão e que o auto-implante esplênico é eficaz na restauração do seu controle.
