The rats in group C were given A. muricata leaf aqueous
extract (AME, 100 mg/kg, p.o.) as from day 5 post STZ injections, and stopped on
the 30th day of the study period. The pancreases of the rats were excised and
randomly processed for histological staining and biochemical assays for antioxidant
enzymes [such as glutathione (GSH), superoxide dismutase (SOD), glutathione
peroxidase (GSH-Px), catalase (CAT), malondialdehyde (MDA) and serum nitric
oxide (NO)].
