ABSTRACT
Technical grade dinitrotoluene (tg-DNT) [CH3C6H3 (NO2)2] nitroaromatic agents which are manufactured in theindustries and applied in both commercial and military in all over the world and Egypt. DNT causes malfunctions inkidneys, heart, liver, testes and mammary glands in animals and human beings, which may be considered as carcinogenic inexperimental animals and human. Moreover, taurine, a free β-amino acid with remarkable antioxidant activity, hasimportant beneficial effects on the human body; hepatoprotection, nephroprotection, cardiovascular protection,hypoglycemic impact and hypolipidemicaction. Currently, taurine level in the serum is used as early marker of breast,endometrial and colon cancers. The current research was aimed to explore the potential impacts of the antioxidantproperties of taurine as a protecting material on tg-DNT induced toxicity in the liver and kidney in male rats. 100apparently healthy male rats in 4 groups were included; the first is Frank control group, mouth feeding via gavage withdistilled water; the other groups were administered as following, taurine alone, tg-DNT alone (toxic group), taurine + tgDNT (protective group) in the second, third and fourth groups, respectively. In these groups, blood biochemistry and taurineconcentrations in serum were measured for all animals. Furthermore, histopathological examination studies for liver andkidney were done for all groups. The results showed that, the protective group has marked improvement in most biochemicalparameters than the toxic group. Histological studies revealed a significant marked disturbance in the histopathologicalarchitectures of the kidney and liver in all toxic rats. However, marked improvements in histological architectures wereobserved in protective group. The results support the ameliorative effect of taurine as a protective agent against tg-DNTtoxicity in experimental rats.
