Resumo
Estudou-se a influência do tratamento diário com filtrado aquoso de Agaricus blazei Murrill (ABM) (25mg/ml), via oral, por 17 e 57 dias, em camundongos inoculados com tumor sólido de Ehrlich (TSE) por meio da curva de crescimento tumoral, do peso relativo do tumor, da contagem de regiões organizadoras de nucléolos (AgNORs) e dos padrões histológicos das massas tumorais e linfonodos poplíteos. Os animais que ingeriram o extrato aquoso do ABM por 57 dias apresentaram menor (P<0,05) crescimento do TSE, no segundo e terceiro dias, fase inflamatória do crescimento tumoral. Quanto ao peso relativo das massas tumorais, valores de AgNORs, padrões morfoistopatológicos do TSE e ocorrência de processos metastáticos, não houve alteração significativa (P>0,05) entre os animais tratados e não tratados.(AU)
The influence of daily administration of Agaricus blazei Murrill (ABM) aqueous solution (25mg/ml) during 17 and 57 days in mice bearing solid Ehrlich tumor was studied. Tumoral growth, tumoral and spleenic relative weights, nucleoly organization regions AgNORs values and tumor and popliteal lymph nodes histopathology were daily evaluated. The animals that received ABM during 57 days showed lower values (P<0.05) of tumoral growth on second and third days after the period corresponding to the inflammatory phase of tumoral growth. The relative weight of the tumor and AgNORs values were similar (P>0.05) between treated and non-treated animals. No difference in microscopic evaluation of the tumors in treated and non-treated animals was seen and metastasis in popliteal nodes of the tumor occurred in all the animals.(AU)
