Effect of Gymnopetalum Cochinchinensis on Blood Glucose Level in Normal and Alloxan- Induced Diabetic Mice

Effect of Gymnopetalum Cochinchinensis on Blood Glucose Level in Normal and Alloxan- Induced Diabetic Mice

Gymnopetalum cochinchinensis (LOUR) KURZ fruit is traditionally used by local practitioners of Jaintia Hills of Meghalaya for treating various types of ailments including diabetes. The aqueous extract of the fruits was tested for its hypoglycemic and anti- hyperglycemic effects in both normal and alloxan-induced diabetic mice. Hypoglycemic and anti-hyperglycemic activity was observed to be dose- and time- dependent. The aqueous extract reduced blood glucose level 2 h following administration in both normal and alloxan-induced diabetic mice. In alloxan- induced diabetic mice, blood glucose was markedly reduced to 56% from that of control at 4 h, while in normal mice the blood glucose level was 59% from that of control. Maximum reduction was observed at 6 h in alloxan-induced diabetic mice. Glucose tolerance was also improved in both normal and diabetic mice. The results were compared against those of insulin, glibenclamide, metformin, and the possible mechanism of action discussed.

Effect of Sorghum-tigernut Ibyer (A Traditional Gruel) on the Fasting Blood Glucose Levels of Alloxan-induced Diabetic Rats

Effect of Sorghum-tigernut Ibyer (A Traditional Gruel) on the Fasting Blood Glucose Levels of Alloxan-induced Diabetic Rats

rat groups fed with samples containing higher amounts of tigernut had lower fasting blood glucose levels than those of the control group. This could be attributed to the fact that tigernut is a rich source of fibre [29,30]. Fibre has been reported to exert some hypoglycaemic effects in subjects with type II diabetes. It is also reported that arginine an amino acid (not determined) found in tigernut has the potential of stimulating the release of insulin thereby ameliorating the effect of diabetes [31]. This could be one of the reasons for the lowered blood glucose levels after three days of consecutive feeding with the test diet. Several studies have shown that sorghum extracts and sorghum rich diets exert hypoglycaemic effects in either human subjects or lab animals, thus agreeing with the findings of this research [32,33].

The mechanism of decreasing blood glucose levels in Ficus bengalensis is thought due to presence of a glycoside called leucopelargonidin in leaves, wound healing activity is due to enhanced wound contraction it would have either enhanced contractile property of myofibroblasts or increased the number of myofibroblasts recruited in the wound area, In Trigonella foenum-graecum foenum- fracecum is thought due to presence of insulin secretion stimulating compound 4- hydroxy isoleucine in seeds which decreasing blood glucose levels and wound healing activity is due to releases its anti- inflammatory properties and works to maintain the healing process and reduce the inflammation that is no longer needed as the wounds heals. Fenugreek seeds contain fatty acids which build collagen that is promoted wound healing and maintain skin elasticity [20,21].

An aqueous extract of pods of the plant at a dose of 250mg/kg of body weight significantly reduces blood glucose level in normal and alloxane induced diabetic rats. Cyamopsis tetragonoloba showed marginal antihyperglycemic effect on blood glucose level in normal fasted rats, however, the blood glucose lowering effect was significant in alloxane-induced hyperglycemic rats. The fall was seen at 1hr and remained up to 3hr after administration of extract. Sub acute treatment with aqueous extract of Cyamopsis tetragonoloba on alloxan-induced hyperglycemic rats produced consistent reduction in blood glucose level. Authors suggest that; this effect can be attributed due to presence of flavanoids and other phenolics of the plant (Mukhtar et al, 2004).

Effect of Syrian Capparis Spinosa Leave Extract on Alloxan-Induced Diabetes in Rats

Effect of Syrian Capparis Spinosa Leave Extract on Alloxan-Induced Diabetes in Rats

Rat treatment with alloxan (150 mg/kg/ip) caused a critical rise in glucose levels (250- 600 mg/dl) after three days of injection. It also caused a reduction in body weight and an increase in values of certain biochemical parameters, such as serum SGPT and creatinin. Alloxan didn’t affect the total cholesterol level. In the present study, we used the alloxan-induced diabetes in rat to investigate the effect of CS leave extract in normalizing the blood glucose level, the serum SGPT or ALT levels as a marker of safe liver function, the serum creatinin level as a marker of renal dysfunction, and the total cholesterol level and body weight increment. We investigated the effect of different single oral doses of CS leave extract in normalizing the blood glucose level in diabetic rats. The dose of 400 mg/kg/po had shown the most effectiveness in reducing the blood glucose concentration, so it was chosen in subsequent experiments. It reduced significantly the blood glucose concentration from 404.83±72.10 mg/dl to 239.5±50.73 mg/dl after 8 hours of diabetic rat treatment (p<0.05), and to 213.33±50 mg/dl after 24 hours of treatment (p<0.01, table 4).

Hypoglycemic Effect Study of a Combination of Some Stipulated Spices in Alloxan Induced Diabetic Wistar Albino Rats along with Nutritional Value Evaluation

Hypoglycemic Effect Study of a Combination of Some Stipulated Spices in Alloxan Induced Diabetic Wistar Albino Rats along with Nutritional Value Evaluation

DOI: 10.4236/jdm.2018.82005 50 Journal of Diabetes Mellitus Table 5 represents the proximate composition of the mixed spices. The analyses showed that, macronutrients such as carbohydrate, protein, fat were present in the mixed spices at satisfactory level in all cases. The carbohydrate content of the stipulated mixed spices was 52.34%, which is obviously an adequate amount in terms of spices. Therefore, surely, the sample will meet the daily requirement of carbohydrate. In case of fat content, it was found to have around 7.76% which is low in amount and good enough in all respects. Again, the dietary fiber content was satisfactorily high (30.51%) in the mixed spices which made the recipe unique as many studies showed beneficial effects of dietary fiber in diabetic sub- jects imparting the blood glucose level lowering capabilities and decreasing the glycemic index of foods [26]. The levels of all other associated nutrients includ- ing protein were up to the mark.

HYPOGLYCAEMIC EFFECT OF AQUEOUS EXTRACT OF BENINCASA HISPIDA IN RABBITS .......

HYPOGLYCAEMIC EFFECT OF AQUEOUS EXTRACT OF BENINCASA HISPIDA IN RABBITS .......

Present study was designed to evaluate hypoglycaemic effect of aqueous extracts of Benincasa hispida stem. Rabbits of either sex weighing 2 – 2.5 kg were included in the study. Alloxan monohydrate was given 120mg/kg i.p. to induce experimental diabetes. The animals with fasting blood glucose levels 200-250mg/dl were included in the study. The animals were divided into five groups. Group one and two received 1ml of normal saline (negative control), 0.5mg/kg of glibenclamide (Positive control) and the other three groups were received graded doses of aqueous extract of test drug (Benincasa Hispida) i.e., 50mg/kg, 100mg/kg and 200mg/kg respectively. The glucose estimation was done by a glucometer (Accu-Chek, Roche Diagnostics, USA) and the blood was obtained by puncturing marginal vein of the rabbit’s ear. The extracts showed dose-dependent significant (P < 0.05) reduction in the blood glucose levels, when compared with that of the control rabbits. The most effective percentage reductions in blood glucose level were observed at 200mg/kg. From the experimental findings, it is possible to conclude that aqueous extracts of Benincasa hispida studied exhibited promising hypoglycaemic activity in alloxan-induced diabetic rabbits.

Antidiabetic Effect of Leaves of Muntingia Calabura L., in Normal and Alloxan-Induced Diabetic Rats

Antidiabetic Effect of Leaves of Muntingia Calabura L., in Normal and Alloxan-Induced Diabetic Rats

Methanolic extracts of leaves at dose of 500 mg/kg exhibited significant and consistent (p<0.001) reduction in blood glucose levels in normoglycemic euglycemic rats and alloxan induced diabetic rats at 4 hr and was maximum at the end of 6 hr. This effect is comparable to that produced by standard drug, Glipizide (5 mg/kg b.wt). Muntingia calabura L. leaf extract (500 mg/kg b.wt) is well tolerated and markedly reduced the progressively elevated blood glucose levels in glucose loaded rats. The hypoglycemic effect was significantly (P<0.001) pronounced from 60 to 90 min when compared to control group. This indicates that the extract may be acting by direct stimulation of existing ß-cells to release insulin or increase the glucose uptake. Our investigations revealed that the Muntingia calabura L. leaf extract effectively regulated the blood glucose levels in normal euglycemic rats and alloxan induced diabetic rats indicating the presence of antidiabetic activity.

ANTI  DIABETIC ACTIVITY OF BRUGUIERA GYMNORHIZA ROOT

ANTI DIABETIC ACTIVITY OF BRUGUIERA GYMNORHIZA ROOT

The different extracts of the roots of Bruguiera gymnorhiza (Family- Rhizophoraceae) were tested for anti-diabetic activity, by glucose tolerance test in normal rats and alloxan induced diabetic rats. Aqueous ethanol and butanol extracts had shown significant protection and lowered the blood glucose levels to normal in glucose tolerance test. In alloxan induced diabetic rats the maximum reduction in blood glucose was observed after 3h at a dose level of 250 mg/kg of body weight. The percentage protections by aqueous ethanol and butanol extracts were 30 and 48% respectively. In long term treatment of alloxan induced diabetic rats, the degree of protection was determined by measuring blood glucose, triglycerides, cholesterol and urea levels on 0,3,5,7 and 10th day. Both the extracts showed a significant anti- diabetic activity comparable with that of glibenclamide. The histopathological studies during the long-term treatment have shown to ameliorate the biochemical damages caused by alloxan. These results indicate that the B. gymnorhiza root possess significant anti -diabetic activity.

Antidiabetic and Antihyperlipidaemic Effects of Solanum Xanthocarpum Total Extract in Alloxan Induced Diabetic Rats.

Antidiabetic and Antihyperlipidaemic Effects of Solanum Xanthocarpum Total Extract in Alloxan Induced Diabetic Rats.

The antidiabetic and antihyperlipidaemic effects of aqueous-methanol (40:60) extract of Solanum xanthocarpum whole plant (Sx) were investigated in normoglycemic, glucose fed, and alloxan-induced diabetic rats. In normoglycemic rats, the powdered extract of Sx, administered at doses of 200 mg/kg and 400 mg/kg b.w x 1 p.o. resulted in reduction of blood glucose level by 10.55% and 12.83% respectively. In glucose fed diabetic rats, the reduction of blood glucose level was also achieved dose dependently and significantly compared to the vehicle control group. In another experiment, powdered Sx extract was administered daily at doses of 200 mg/kg and 400 mg/kg p.o., for 7 days, after alloxan administration (150 mg/kg i.p.). The treatment showed significant dose-dependent percentage blood glucose lowering in the diabetic rats. This effect of Sx was comparable to that of a reference standard drug, glibenclamide (10 mg/kg b.w p.o. x 7). Additionally, the Sx plant extract also had potent antihyperlipidaemic activity and was found to improve the lipid levels of alloxan induced diabetic rats at the end of the treatment period. Phytochemical screening of the Solanum xanthocarpum total plant extract showed the presence of spirosta-steroidal saponins, amino acids, phytosterols, flavonoids, glycoalkaloids, tannins and tarpenoids, many of which were previously unreported and now contributed to the bioactivity of Sx.

Each ethanolic extract used in this study possessed active compounds that were well-reported to reduce blood glucose level. Furthermore, herbal extract combination showed synergistic effect in lowering blood glucose level in alloxan-induced diabetic rats, even at 200 mg/kgBW (lowest dose in the study). However, the dose used to achieve the optimum effect was obtained at dose of 800 mg/kg BW.Therefore, the next step is to fractionate and purify the extracts so that the dose of the combination can be reduced. Combination of ethanolic extracts of A. paniculata and A. indica provides various anti-diabetic compounds. The diversity of active compounds in the herbal extract comination may synergistically increase antihyperglycemic effect and may give an alternative in diabetes therapy. However, exploration related to the mechanism of action of each active compound from ethanolic extract remains to be elucidated.
