ABSTRACT
Objective@#To study the toxicological effects of Nao-de-kang on rats.@*Methods@#According to the digital table, SD rats were randomly divided into blank group and Nao-de-kang small dose group(3.85g/kg), high dose group(7.71g/kg) and maximum tolerated dose group(77.14g/kg), 20 rats in each group, half male and half female.All groups were treated for 12 weeks, and the maximum tolerated dose group was treated for 1 week.The animal activity during treatment, the blood routine indicators, blood biochemical index and the organs for pathological examination were recorded and compared.@*Results@#There was no mortality in the dose group of rats in the experimental period.The weights of 4 groups had no statistically significant differences during treatment(F=0.688, 0.540, 0.121, 0.065, 0.128, 0.239, 0.199, 0.378, 0.127, 0.446, 0.906 and 0.665, P=0.562, 0.585, 0.886, 0.937, 0.880, 0.788, 0.820, 0.687, 0.881, 0.642, 0.410 and 0.518), male and femal′s red blood cell(RBC)(♀: F=0.178, P=0.910, ♂: F=0.119, P=0.948), hemoglobin(HGB)(♀: F=0.046, P=0.987, ♂: F=0.072, P=0.975), hematokrit(HCT)(♀: F=0.126, P=0.944, ♂: F=0.054, P=0.983), platelet(PLT)(♀: F=0.515, P=0.675, ♂: F=0.500, P=0.685), white blood cell(WBC)(♀: F=0.078, P=0.972, ♂: F=0.057, P=0.982), eosnophils(Eos)(♀: F=0.078, P=0.972, ♂: F=0.057, P=0.982), lymphocyte(Lym)(♀: F=0.078, P=0.972, ♂: F=0.057, P=0.982), neutrophilic granulocyte(Neu)(♀: F=0.134, P=0.939, ♂: F=0.090, P=0.999), alanine aminotransfease (ALT)(♀: F=0.572, P=0.637, ♂: F=0.200, P=0.896), aspartate aminotransferase(AST)(♀: F=0.572, P=0.637, ♂: F=0.200, P=0.896), total protein(TP)(♀: F=0.665, P=0.579, ♂: F=0.343, P=0.795), albumin(ALB)(♀: F=0.533, P=0.663, ♂: F=0.668, P=0.577), triglyceride(TG)(♀: F=0.843, P=0.480, ♂: F=0.561, P=0.644), cholesterol(CHOL)(♀: F=0.245, P=0.864, ♂: F=0.046, P=0.987), glucose(GLU)(♀: F=0.216, P=0.884, ♂: F=0.095, P=0.963), urea nitrogen(BUN)(♀: F=0.172, P=0.914, ♂: F=0.203, P=0.894)and creatinine(Cr)(♀: F=0.172, P=0.914, ♂: F=0.203, P=0.894) had no statistically significant differences.@*Conclusion@#Nao-de-kang has no obvious side effect.
