Introduction and Aim: The management of diabetes is a great challenge in this era due to several factors. The financial burden of the medications and the complications of diabetes create management demanding especially in the Indian population. A high protein-rich diet is beneficial in controlling hyperglycemia in diabetic patients. Different amino acids play roles in reducing blood glucose levels in diabetes. Certain amino acids trigger hypoglycemia in diabetes by inducing the gut hormone, Glucagon-like peptide -1(GLP-1) secretion. L-tryptophan is one among them and is present in many of the food items like poultry, beans, seeds, nuts, etc., This study using albino rats focuses on the effect of L-tryptophan on intestinal GLP-1 secretion in diabetic rats by evaluating the blood glucose level, intestinal GLP-1, and intestinal histology of diabetic rats after tryptophan administration.Materials and Methods: Single dose of intraperitoneal injection of STZ (50mg/kg) used to develop diabetic model and orogastric gavage of tryptophan (50mg/kg) was done. Intestinal GLP-1 and blood glucose assay and intestinal histology were the parameters studied.Results: The results showed a significant reduction in blood glucose level and an increased secretion of intestinal GLP-1(p=0.001) in diabetic rats by tryptophan administration and recovery was seen in intestinal histology. In conclusion, in our study, the administration of L- tryptophan in diabetic rats induced a hypoglycemic effect by GLP-1 secretion and restored normal histology.Conclusion: Tryptophan administration showed hypoglycemic effect on diabetic rats as the blood glucose level was reverted to normal and the hypoglycemic effect of L-tryptophan in diabetic rats could be due to increased GLP-1 secretion.

Aims: To investigate the effect of food blends (plantain, soybean and ginger) on the blood glucose, lipid profile and haematological indices on streptozotocin induced diabetic rats. Methodology: A total of 35 rats of mean body weight 219.07 g separated into7 groups (5 per group) where induced by a single intraperitoneal (I.P) injection of streptozotocin (0.1 g dissolved in 5 ml of freshly prepared sodium citrate buffer 0.1 M, pH 4.5) at a dose of 40 mg/kg body weight after fasting for 12 hours and fed with flours/blends. The flours were produced from plant materials for different treatments/blends (blend A=100% unripe plantain, B=80% unripe plantain, 14% soybean, 6% ginger, C=70% unripe plantain, 26% soybean, 4% ginger, D= 60% unripe plantain, 38% soybean, 2% ginger, E= 50% unripe plantain, 50% soybean) and the phytochemicals and minerals content were determined. Blood glucose was determined at 5 days interval for 25 days. Diabetes was confirmed in rats with blood glucose concentrations >200 mg/dl. After 25 days rats were anaesthetized with chloroform vapour and blood samples collected by cardiac puncture for haematology and lipid profile determination. Results: The results showed that unripe plantain, soya beans and ginger in adequate proportion(C=70% unripe plantain, 26% soybean, 4% ginger or D= 60% unripe plantain, 38% soybean, 2% ginger) could help to reduce blood glucose, improve haematological parameters and lipid profile. Significant reduction was observed in the blood glucose level of rats fed blends C and D from 286 to 85 mg/dl and 307 to 90 mg/dl respectively at the end of experiment. These results also demonstrated that the inclusion of ginger at 6% causes rise in blood glucose level. Total cholesterol (TC) increased in all the blends. However, the lowest concentration of TC was observed in blends C and D. The highest packed cell volume (60%) and Haemoglobin (20 g/dl) level observed in rats fed blend C was significantly higher than the normal control fed conventional feeds. The increase in packed cell volume (PCV) (50%) and Hb (17 g/dl) in diabetic rats demonstrated that the formulated blend C was able to raise PCV and Hb above 50% and 17 g/dl (Normal control NC) respectively. Significant increase (P<0.05) in low density lipoprotein cholesterol (LDLc) was also observed in all the blends with blend C having the least (4.0 mg/dl) close to NC (2.0 mg/dl). Conclusion: From the results it is evident that blend C will manage and improve the health status of diabetic patients.

Combination therapy is considered as a new and effective therapeutic strategy for control of hyperglycemia. The present study aimed to determine the hypoglycemic effect of Afghan Hibiscus sabdariffa L. and Carum Carvi L. hydro-alcoholic extracts either alone or in combination on diabetic rats. Streptozotocin-induced diabetic rats were administered intraperitoneally with hydro-alcoholic extracts of H. sabdariffa (75, 150 and 300 mg/kg), C. carvi (150, 300 and 500 mg/kg) and their combinations for 21 days. The Fasting blood glucose and body weight of rats were determined on 0, 7, 14 and 21st days. The results showed a significant (P<0.0001) hypoglycemic effect of H. sabdariffa extract (75, 150 and 300 mg/kg) on 7, 14 and 21th days, C. carvi extract (500 mg/kg), and their effective doses combination (75:25), especially on 7th day. Only 75 mg/kg of H. sabdariffa had positive effect on body weight loss of diabetic rats (P<0.05). One can conclude that Afghan H. sabdariffa and C. carvi hydro-alcoholic extracts and their combination have a hypoglycemic effect. However, their combinations do not have any synergic effects, so the hypoglycemic effect of H. sabdariffa was much greater and even normalized the blood glucose level.

The available drugs for the treatment of diabetes, such as Insulin or Oral hypoglycemic agents have one or more side effects. So the search for newer anti-diabetic drugs with minimum or no side effects from herbal plants is a challenge as per world health organization (WHO) recommendations. Diabetes mellitus is a metabolic disorder of carbohydrate, protein and fat which are characterized by hyperglycemia, polyuria, polydipsia, and polyphagia which is deficient insulin production or ineffectiveness in insulin actions. The present study was aimed to evaluate the anti diabetic potency of syzygium cumini leaf on the blood glucose level in alloxan induced diabetic rats. Diabetic Wistar strain rats were treated with standard drug Glibenclamide and test drug syzygium cumini at 100mg, 200mg. The hypoglycemic effect was determined in the rats and the efficacy of the test drug was compared to the standard drug Glibenclamide. Syzygium cumini leaf was orally administered for 14 days in alloxan induced diabetic rats. At the end of the study duration blood glucose level and Biochemical parameters were statistically analyzed. Based on these results of the study this syzygium cumini produced a significant reduction in blood glucose levels when compared with diabetic control rats and hence the present research work proved that the syzygium cumini possess hypoglycemic effect.

In recent years,green tea and ginger have become a subject of interest because of their beneficial effects on human health. The aim of the present study was to compare the effect of long term administration of green tea and ginger each alone to the effect of their combination on blood glucose level in streptozotocin-induced diabetic rats. Method: A group of 50 male albino rats was divided into five groups (10 rats each group). The normal control group( NC) administered tap water, other animals were injected by streptozotocin 45mg/Kg body weight intraperitonially to induce diabetes mellitus and then divided into four groups ,diabetic control (DC) without treatment, diabetic group administered green tea extract for four weeks (DGT), diabetic group administered ginger extract for four weeks(DGI), and diabetic group administered mixture of green tea and ginger for four weeks (DGG), then we compare the blood glucose level at 1st,2nd,3rd, and 4th week of experiment. Results:We observed that in groups whose water drink was substituted by green tea and ginger extract, the blood glucose level was significantly( p less than 0.05) reduced as compared to diabetic animals. Importantly, we observed that blood glucose level was near control level when green tea was administered simultaneously with ginger extract.Conclusion: Combination of green tea and ginger may be of great value as hypoglycemic agent in diabetic patients, the synergism of their effect on glucose regulation process is underlying this results.
