Effect of T. foenumgraecum on glycogen content of tissues and the key enzymes of carbohydrate metabolism.
The Indian traditional system of medicine prescribed plant therapies for diseases including diabetes mellitus called madhumeh in Sanskrit. One such plant mentioned in Ayurveda is Trigonella foenumgraecum (FG). In the present study, FG (1g/kg PO) was assessed for its effect on glycogen levels of insulin dependent (skeletal muscle and liver), insulin independent tissues (kidneys and brain) and enzymes such as glucokinase (GK), hexokinase (HK), and phosphofructokinase (PFK). Administration of FG led to decrease in blood glucose levels by 14.4 and 46.64% on 15th and 30th day of the experiment. Liver and 2-kidney weight expressed as percentage of body weight was significantly increased in diabetics (P<0.0005) versus normal controls and this alteration in the renal weight (P<0.0005) but not liver weight was normalized by feeding of FG. Renal glycogen content increased by over 10 folds while hepatic and skeletal muscle glycogen content decreased by 75 and 68% in diabetic controls versus controls and these alteration in glycogen content was partly prevented by FG. Activity of HK, GK and PFK in diabetic controls was 35, 50 and 60% of the controls and FG partially corrected this alteration in PFK, HK and GK.
