Efeitos do uso de probiótico sobre a toxicidade do dicromato de potássio no sistema reprodutor masculino e adrenais de ratos Wistar

Abstract

The aim of this study was to evaluate the effect of probiotics on the toxicity of increasing doses of potassium dichromate on the reproductive tract and adrenal glands of rats . Material and Methods: During a trial period of 90 days , we used 80 Wistar rats were divided randomly into 8 groups of 10 animals : GC (control ) , G1 (12 mg.kg - 1 K2Cr2O7 ) ; G24 ( 24 mg.kg - 1 K2Cr2O7 ) ; G36 ( 36 mg.kg - 1 K2Cr2O7 ) ; GP Control ( 0.2% probiotic ); G12P ( 12 mg.kg - 1 K2Cr2O7 + Probiotic 0.2 % ) ; G24P ( 24 mg.kg - 1 K2Cr2O7 + Probiotic 0.2 % ) ; G36P ( 36 mg.kg - 1 K2Cr2O7 Probiotic + 0.2% ) . Subsequently , weighing and histological evaluation of the reproductive organs and adrenal glands was performed , and plasma testosterone dosage . Results: Testes were heavier in group 7 There were statistical differences between the weights of the seminal vesicles only in groups 2:07 Histologically observed development of atypical hyperplasia and squamous metaplasia in the testes and seminal vesicles and degeneration of the germinal epithelium and tubular contraction testes despite the use of probiotics. Conclusion : The use of probiotics has not protected the epithelium of the reproductive system in this study .
