Alterations in hepatic lipid peroxides and antioxidant profile in Indian water buffaloes suffering from sarcoptic mange

The present study was aimed to examine the status of antioxidants in water buffaloes with sarcoptic mange. Sixty-three buffaloes were divided into three groups, healthy control (group I, n = 19), subclinical sarcoptic mange (group II, n = 22) and clinical sarcoptic mange (group III, n = 22). Lipid peroxides (LPO), superoxide dismutase (SOD), catalase (CAT), zinc and copper in hepatic tissues and serum α-tocopherol concentrations were measured. In comparison to group I, LPO was significantly (P < 0.05) higher, while SOD and CAT were significantly (P < 0.05) lower in group III. LPO and SOD activities were comparable between group I and II, but CAT was significantly (P < 0.05) lower in group II. In group III, zinc, copper and α-tocopherol concentrations were significantly (P < 0.05) lower than group I. Decrease in antioxidant enzyme activities and trace mineral concentrations suggested that sarcoptic mange in buffaloes is associated with compromise in antioxidant defense and oxidative stress may play important role in pathogenesis.
