Effect of Terminalia arjuna bark powder on some diagnostic enzymes in buffalo (Bubalus bubalis) ingesting arsenic contaminated water and fodder.

OBJECTIVE

The study investigated the effect of Terminalia arjuna bark powder on some diagnostic enzymes related to hepatic and muscle function in buffaloes ingesting arsenic contaminated water and fodder in an arsenic affected area.

METHODS

A total of 25 samples of tube well water, fodder and buffalo blood were collected through a survey from arsenic contaminated areas and 20 samples from the uncontaminated, i.e., control areas of Ludhiana district, Punjab for determination of arsenic concentration. A total of 30 buffaloes (selected from above 45 animals) were divided into three groups of 10 each on the basis of blood arsenic level, viz., control group: Clinically healthy buffaloes from the uncontaminated area with the blood arsenic level within the normal limit (0-0.05 ppm); Arsenic exposed group: Buffaloes exposed to arsenic through intake of contaminated water and fodder in the arsenic affected area with the blood arsenic level above the normal limit of 0-0.05 ppm; treatment group: Arsenic exposed buffaloes treated with T. arjuna bark powder orally at 42 mg/kg b.w. OD for 30 days. Single blood samples were collected from control and arsenic exposed groups. Blood samples from the treatment group were collected on 0, 15th, and 30th day of treatment along with one sample on the 45th day, i.e., after withdrawal of treatment. Activities of alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), lactate dehydrogenase (LDH), and creatine kinase (CK) were assayed in plasma.

RESULTS

Significantly (p<0.05) higher arsenic concentration was observed in tube well water, fodder and buffalo blood samples collected from the arsenic contaminated area. A significant positive correlation was noticed between arsenic concentrations of tube well water, fodder and untreated buffalo blood samples, collected from the arsenic affected area. ALP, GGT, LDH, and CK activities were significantly (p<0.05) increased in the arsenic exposed buffaloes compared to control. Treatment with T. arjuna bark powder reduced the plasma levels of ALP, GGT, LDH, and CK in arsenic exposed buffaloes comparable to that of control.

CONCLUSIONS

Exposure to arsenic altered the hepatic and muscle function enzymes in buffaloes. T. arjuna bark powder supplementation lowered the ALP, GGT, LDH, and CK activities in arsenic exposed buffaloes toward the values exhibited by the control group.
