Summary:
The antioxidative and antidiabetic effect of pomiferin was monitored under the experimental
conditions of alloxan-induced diabetes mellitus. The animals were divided by random selection
into 2 groups (n=7). The treated group was administered pomiferin in peroral doses of 10 mg/kg
in Avicel, the placebo group was given only a solution of Avicel, and the last group was intact.
Selected laboratory parameters (glucose, urea, cholesterol, antioxidative enzymes, total
antioxidative capacity, malondialdehyde in serum; diuresis, total glucose and protein losses
through urine) were determined. Kidney tissue and pancreas samples were taken for
histopathological analysis. The findings included a statistically significant decrease (p≤0.01) in
blood glucose level, a significant increase (p≤0.01) in glutathione peroxidase, total antioxidative
capacity (p≤0.05) and a significant decrease (p≤0.01) in malondialdehyde level in the treated
group compared to the placebo group. A highly significant decrease (p≤0.01) in diuresis, glucose and protein losses through urine were identified in the treated group compared to the placebo
group. The superoxide dismutase catalytic activity, urea and cholesterol levels involved nonsignificant
changes. The results of biochemical examination show a protective antioxidative and
antidiabetic effect of pomiferin. The results of histopathological examination correlate with them
only partially.
Key words:
pomiferin – diabetes mellitus – antioxidant
