چکیده (انگلیسی):

Diabetes is a metabolic disorder characterized by hyperglycaemia and it is fast becoming a
scourge in sub-Saharan Africa. The nutritional properties of developed fibre-enriched cake
and its protective potential against diabetic induced neurotoxicity in rats were investigated.
Fibre-enriched cake was developed from selected fruits and analysed for its nutritional and
sensory attributes. Rats were induced with diabetes by a single intraperitoneal injection
of alloxan and treated with the formulated cake. After 14 days treatment, the rats were
sacrificed by cervical dislocation. Their brain tissues were accessed for reduced glutathione
(GSH), catalase, superoxide dismutase (SOD) activities, protein content and lipid peroxidation
as well as lipid profiles which cover for total cholesterol, triglycerides, HDL and LDL.
Induction of diabetes led to significant reduction (p < 0.05) of GSH, catalase, SOD activities
and protein content. Feeding on the formulated cake led to their significant increase.
Decreased lipid peroxidation, total cholesterol, LDL and triglycerides, and increased concentration
of HDL were also observed on feeding with the cake. These results indicate an
antioxidant protective potential of the fibre-enriched cake against diabetic-induced brain
toxicity. Thus, it can serve as an adjunct to dietary therapy for diabetes.
