Cadmium is the second most hazardous metals with bio-concentration factor (BCF) > 100 Although WHO permitted cadmium concentration in drinking water is 0.005 mg/L, yet the reality is far above to this limit because of industrial utility of this metal. Oral exposure of cadmium to human results in dreadful symptoms of metabolic disorders especially in liver and kidneys. Endogenous protection could be supported by some exogenous herbal supplement (viz., Catharanthus roseus in this case) to overcome the toxic effects. Present Study has been designed to find out the functional renal changes under the effect of cadmium and Catharanthus roseus in the model organism albino rats. Cadmium significantly (p > 0.01) increases the level of nitrogenous waste (Urea, BUN, Uric Acid and Creatinin), while decreases the serum protein profile in acute and sub-acute sets. Urea concentration of control ranged from 16.56 to 17.72 mg/dl while that of Group-B and D were 19.84 to 20.87 mg/dl and 17.56 to 17.59 mg/dl respectively. Similarly uric acid concentration ranged in control form 6.98 to 8.01 mg/dl in group-B from 7.58 to 10.25 mg/dl, in Group-D 8.02 to 8.59 mg/dl respectively. Creatinin concentration ranged in control 0.57 to 0.65 mg/dl, in group-B 0.97 to 1.02 mg/dl, in group-D – 0.95 to 0.98 mg/dl respectively.These results might be due to altered filtration rate of kidney because of protein disruption. The studies conclude the efficient nephro-protection offered by Catharanthus roseus extract against Cadmium toxicity. Keywords: Cadmium, Catharanthus roseus, Nephrotoxicity, Rattus norvegicus
