| dc.description.abstract | ABSTRACT : An experiment was conducted to study the ameliorating effect of Caesalpinia sappan in lead toxicity using a total of 24 male wistar rats which were randomly divided into four groups consisting of six animals in each group. Group I was maintained on basal diet as control and group II on lead acetate @ 90 mg/kg orally along with basal diet as toxic control group. Group III was maintained on methanolic extract of Caesalpinia sappan stem bark @ 100 mg/kg along with the basal diet and group IV on lead acetate @ 90 mg/ kg and methanolic extract of Caesalpinia sappan @ 100mg/ kg along with the basal diet for 28 days. The serum biomarkers were estimated for assessing the damage caused to liver, kidney and heart due to lead toxicity. Parameters like total protein, ALT, troponins, AST, creatinine and BUN values were measured on Day 14 and Day 28 from freshly collected blood samples. Tissue samples were collected and preserved at -20ᵒC for analysis of tissue antioxidant profile (TBARS, glutathione, GST, SOD, catalase, membrane ATPases, Vitamin E and C) and lead content. Blood samples were collected and haematological parameters (RBC, WBC, Hb and PCV) were estimated at the end of 28th day of experiment. The results indicated that lead toxic group (group II) showed a significant (p<0.05) decrease in serum total proteins and significant (p<0.05) increase in ALT, troponins, AST, creatinine and BUN values revealing that lead has induced damage to the liver, kidney and heart tissues. Significant decrease in total RBC count, haemoglobin and PCV were observed in group II which showed the evidence of damaging effect of haemopoietic system due to lead toxicity. The mean values of TBARS were significantly increased in lead control group where as the levels of glutathione, GST, SOD, total membrane ATPases and Vitamin E were significantly decreased in group II indicating lead induced oxidative damage to the tissues. Significant increase in the levels of lead was observed in liver and kidney in group II. Treatment with methanolic extract of Caesalpinia sappan stem bark (group IV) resulted in improvement in above parameters as compared to lead toxic group (group II). Lead quantity of the liver was reduced slightly in group IV compared to group II but could not bring the levels to normal. Thus, it is concluded that lead induces biological damage to liver, kidney and heart tissues and further caused oxidative stress and Caesalpinia sappan offered amelioration which is attributed to its antioxidant activity but it could not able to reduce the lead content of the tissues completely. | en_US |
