Abstract: Este trabalho teve por objetivo verificar se o teor proteico da dieta, afeta a génese dos tecidos de reparo em ratos que sofreram implante de esponja de policlorovinil (PVC), como também analisar através da histofotometria, as possíveis alterações na síntese de mucopolissacarídeos ácidos (glicosaminoglicanos). Foram utilizados 45 ratos machos wistar, com 21 dias de idade, subdivididos em 3 grupos experimentais, submetidos durante 69 dias a dietas contendo respectivamente 6%, 15% e 40% de proteína. Os animais submetidos á dieta hipoprotéica, contendo 6% de proteína, apresentaram urna inibição na evolução e maturação do tecido de granulação principalmente aos 4 ,7 e 10 dias após o implante da esponja de PVC, apresentando menor infiltração de células inflamatórias, menor proliferarão de fibroblastos, redução da formação de fibras colágenas, neovascularizagáo diminuída e inibição da síntese de mucopolissacarídeos ácidos.

Forty five Wistar weanling male ratas, at 21 days of age, were divided into three experimental groups; the groups were fed diets al 6%, 15% and 40% protein level from casein source, during at 69 days period. The animals which received the low protein diet (6%) presented an inhibition in the evolution and maturation of the granulation tissue mainly in the 4th, 7th and 10th days after the sponge PVC implantation. It was also observed that there was less infiltration of the inflammatory cells, less fiberblasts proliferation, reduction of othe collagen fibers synthesis, neovascularization decreased and an inhibition of the mucopolysaccharide acids synthesis.
