OBJECTIVE: To evaluate anti-hyperglycemic and anti-oxidative effects of Lcarnitine in alloxan induced diabetic albino wistar rats.
METHODS: This quasi-experimental study was conducted at Isra University,
Hyderabad from June 2017 to August 2017. Thirty-six albino wistar male rats
were equally divided into 3 groups (n=12/group); group A (control), group B
(alloxan 150mg/kg intraperitoneally) and group C (alloxan 150mg/kg
intraperitoneally + L-carnitine 500mg/kg orally for 21 days). Diabetes was
induced in group B and C by single intraperitoneal dose of alloxan 150mg/kg
body weight and rats having blood glucose >200mg/dl were labeled as diabetic
rats and included in study. Biochemical (blood glucose, serum insulin and
glutathione peroxidase) and histopathological analysis of pancreas was
performed in all three experimental groups.
RESULTS: Post-experimental body weight in groups A, B and C were noted as
249.58±6.63, 199.08±12.18, 210.58±5.14 grams respectively. The fasting
blood glucose in groups A, B and C were noted as 104.58±7.05, 221.25±8.22,
110.17±12.85 mg/dl respectively (P<0.001). Serum insulin in groups A, B and
C was noted as 1.45±0.083, 0.31±0.16, 1.74±0.23 ηg/ml respectively
(P<0.001). Glutathione peroxidase levels in groups A, B and C were noted as
1.45±0.17, 0.93±0.11, 1.74±0.17 ηg/ml respectively (P<0.001).
Histopathology of pancreas showed reduction in size (mean islet diameter
157±1.5 µm) and number of islets of Langerhans in diabetic rats, while Lcarnitine treated rats have shown compensatory increase in size of islets of
Langerhans (mean islet diameter 210±6.3 µm).
CONCLUSION: L-carnitine therapy is a potent anti-hyperglycemic and antioxidative regimen capable of reducing blood glucose and increasing plasma antioxidant levels
