Enzyme changes and glucose utilisation in diabetic rabbits: the effect of Gymnema sylvestre, R.Br.
The administration of the dried leaf powder of Gymnema sylvestre regulates the blood sugar levels in alloxan diabetic rabbits. G. sylvestre therapy not only produced blood glucose homeostasis but also increased the activities of the enzymes affording the utilisation of glucose by insulin dependent pathways: it controlled phosphorylase levels, gluconeogenic enzymes and sorbitol dehydrogenase. The uptake and incorporation of [14C] glucose into the glycogen and protein are increased in the liver, kidney and muscle in G. sylvestre administered diabetic animals when compared to the untreated diabetic animals. Pathological changes initiated in the liver during the hyperglycemic phase are reversed by controlling hyperglycemia by G. sylvestre. G. sylvestre, a herb used for the control of diabetes mellitus in several parts of India, appears to correct the metabolic derangements in diabetic rabbit liver, kidney and muscle.
