Metformin is now being recognized as the standard therapy in T2D patients who are overweight. Metformin has many drug-disease interactions that can increase the risk of metformin-associated lactic acidosis. Therefore this study was conducted to evaluate any possible pharmacodynamic interactions between metformin and drugs used to treat chronic diseases e.g. Hypertension. The rats were fasted overnight before inducing diabetes with streptozotocin. The rats were given an intraperitoneal injection of streptozotocin (50 mg kg−1) freshly prepared in 0.1M sodium citrate buffer. The diabetic state was confirmed 72 h after streptozotocin injection. Diabetic rats were grouped into seven groups each group of five rats and distributed among the normal control group diabetic control group and the treatment groups. The treatment continued for 10 days. Blood samples were taken before treatment and after 10 days and analyzed for serum glucose, cholesterol, HDL, LDL, and triglycerides. In the diabetic control group which was given STZ alone the blood glucose level decreased significantly (p < 0.05) after 10 days but still above the hyperglycemic level (200mg/dl). The same was observed in the group treated with metformin. The group treated with nifedipine and aspirin showed significant reduction (p < 0.01) in the glucose level below the hyperglycemic level (200mg/dl). While the groups treated with (Metformin + Nifedipine) and (Metformin +Aspirin) showed highly significant reduction (P<0.001) in blood glucose level. These results conclude that the combination of (metformin +Nifedipine) and the combination of (Metformin + Aspirin) have highly significant hypoglycemic effect. It also showed that Nifedipine has promising role in reducing blood glucose level, lipid profile especially LDL-cholesterol, and body weight.

<p>ABSTRACT<br />Context: Several species of the genus Annona were reported to have hypoglycemic properties and this makes Annona reticulata Linn. (Annonaceae)<br />an interesting plant for investigating its anti-hyperglycemic potential.<br />Objective: Different fractions prepared from hydro-alcoholic extract of A. reticulata leave were investigated for their blood glucose lowering effect on<br />Streptozotocin (STZ) induced hyperglycemic rats.<br />Methods: Ethyl acetate, methanol, and residual fractions (at dose level of 100 mg/kg by oral route) prepared from the hydro-alcoholic extract of<br />A. reticulata leave were administered for 14 consecutive days to STZ induced hyperglycemic rats for evaluation of their anti-hyperglycemic potential.<br />Anti-hyperglycemic potential was assessed by observation of a decrease in fasting blood glucose level.<br />Results: The studies revealed that ethyl acetate fraction decreased the blood glucose level of hyperglycemic rats from 447.67 to 234.17 mg/dL and is<br />significant (p&lt;0.001) when compared with diabetic control group. The residual fraction and methanolic fraction decreased blood glucose level from<br />417.83 to 402.50 mg/dL and 432.33 to 371.67 mg/dL respectively but not significant when compared with the diabetic control group. Standard drug<br />metformin (dose 300 mg/kg) reduced the blood glucose level from 447.33 to 219.50 mg/dL.<br />Discussion: Ethyl acetate fraction at tested dose level was capable not only to control the elevated blood glucose level but also able to attenuate<br />certain secondary parameters associated with STZ induced hyperglycemia.<br />Conclusion: This study suggested that the ethyl acetate fraction prepared from hydro-alcoholic extract of A. reticulata leave exhibit potential antihyperglycemic<br />property<br />in the tested<br />experimental<br />models and should be investigated<br />further.<br />Keywords: Streptozotocin, Diabetes, Dyslipidemia.</p>

The present study was designed to investigate the antidiabetic activity of aqueous extract ofAcacia tortilispolysaccharide (AEATP) from gum exudates and its role in comorbidities associated with diabetes in STZ-nicotinamide induced diabetic rats. Male albino Wistar rats were divided into control, diabetic control, glimepiride treated (10 mg/kg), and diabetic rats treated with 250, 500, and 1000 mg/kg dose of AEATP groups and fasting blood glucose, glycated hemoglobin, total cholesterol, triglyceride, LDL, VLDL, HDL, SGOT, and SGPT levels were measured. STZ significantly increased fasting blood glucose level, glycated hemoglobin, total cholesterol, triglyceride, LDL, VLDL, SGOT, and SGPT levels, whereas HDL level was reduced as compared to control group. After 7 days of administration, 500 and 1000 mg/kg dose of AEATP showed significant reduction(P<0.05)in fasting blood glucose level compared to diabetic control. AEATP has also reduced total cholesterol, triglyceride, LDL, VLDL, SGOT, and SGPT levels and improved HDL level as compared to diabetic control group. Our study is the first to report the normalization of fasting blood glucose level, lipid profile, and liver enzyme in AEATP treated diabetic rats. Thus, it can be concluded that AEATP may have potentials for the treatment of T2DM and its comorbidities.

The study was performed to compare the blood glucose lowering effect of Swietenia mahagoni seeds with an oral antidiabetic drug, rosiglitazone in experimentally induced diabetic rats. Twentyfour healthy Long Evans Norwegian strain of rats were included in the study and divided into four groups (A, B, C and D) comprising 6 rats each. Group A (control group) received standard rat food for 14 days. Diabetes was induced by a single intraperitoneal administration of alloxan 120mg/kg body weight in Group B, C and D. Group B was given standard food for 10 days and considered as diabetic control. Group C and D were treated with ethanolic extract of Swietenia mahagoni seeds 1000mg/kg and rosiglitazone 10mg/kg orally respectively. Administration of ethanolic extract of Swietenia mahagoni seeds in group C and rosiglitazone in group D produced a significant reduction in blood glucose level as compared to diabetic control (group B). Histological examination of pancreas showed destruction of beta cells in Islets of pancreas in group B whereas retaining of islets and few degranulations of beta cells of pancreas found in group C and group D. The observations and results of the present study provide information that ethanolic extract of Swietenia mahagoni seeds has hypoglycaemic effect in experimentally induced diabetic rats which requires further investigation.

This research aimed to study the effectiveness of ethanol extract of binahong leaves on blood glucose, insulin, blood chemical profiles (serum glutamic pyruvate transaminase=SGPT, serum glutamic oxaloacetic transaminase=SGOT, ureum, and creatinine), and skin histopathology in diabetic rat. A total of 20 male Wistar rats aged 3 months (± 250 gram) were divided into five groups, with four rats in each group. Group I (non-diabetic control) was injected with 0.1 M sodium citrate buffer, while group II (diabetic control), III, IV, and V were injected with single dose of Streptozotocin (STZ) at dose 40 mg/kg intraperitoneally (IP). One week after the injection, the dorsal skin of the rats were excised. Group I and II were given cream topically and 1% NaCMC orally, group III was given 50% ethanol extract of binahong leaves (EEB) topically and 1% NaCMC orally, group IV was given cream topically and EEB 300 mg/kg orally, and group V was given 50% EEB topically and EEB 300 mg/kg orally. These treatments were continued for 14 days. Blood samples were obtained at the end of study to examine blood glucose, insulin, and blood chemical profiles (SGOT, SGPT, ureum, and creatinine). Examination of skin histopathology and leukocyte count were also done. The result showed that blood glucose, insulin, SGOT, SGPT, and ureum level of diabetic rats given topical or oral EEB did not significantly different from diabetic control group, even though blood glucose, insulin, SGOT, SGPT, and ureum level of diabetic rats given topical and oral EEB were found lower compared to diabetic control group. Administration of EEB 300 mg/kg orally in diabetic rats could lower creatinine level significantly (P<0.05). Histopathological examination of dorsal skin of diabetic rats which were given EEB topically showed the decrease of fibroblast proliferation, leukocyte infiltration, and hemorrhage in dermis area. Leukocyte count on skin tissue was significantly lower (P<0.05) in diabetic rats given EEB. In conclusion, topical or oral administration of EEB can help healing process in diabetic wound.

Objectives: This study investigated the antidiabetic and antihyperlipidemic potential of the ethanol extract of the leaves and stem of Cissus gracillis on alloxan monohydrate-induced diabetic albino rats. Methods: Preliminary phytochemical screening and acute toxicity were carried out. Animals were assigned into seven groups of five rats each. Groups A and B were administered 10 mg/kg each of glibenclamide and atorvastatin respectively, C, D, and E were given 125, 250 and 500 mg/kg of ethanol extract of C. gracillis, respectively, daily for 21 days through oral gavage, group F was diabetic but untreated (diabetic control group), while group G was non-diabetic and untreated which served as the control group. Results: Phytochemical screening revealed the presence of steroids/triterpenoids and carbohydrates. LD50 was above 5000 mg/kg. The extract at 500 mg/kg showed a statistically significant (p<0.05) decrease in blood glucose level when compared with the glibenclamide group on day 21. However, gradual non- significant reduction in blood glucose levels were observed in the extract treated groups on the 7th, 14th, and 21st days of treatment. The administration of ethanol extract of C. gracillis to alloxan-induced diabetic rats produced a decrease in total cholesterol, triglycerides, and low-density lipoproteins comparable to glibenclamide and atorvastatin. Conclusion: The ethanol extract of the leaves and stem of C. gracillis possess a mildly significant antidiabetic and antihyperlipidemic activity.

Objective and Background: In hyperglycemic and alloxan-induced diabetic rats, the effect of Thuja occidentalis methanolic residue extract on blood glucose levels and some biochemical parameters were investigated. Methods: Significantly decreased blood glucose level by 22.85% and 27.66%, in hyperglycemic rats, respectively after 3 h, were seen in a single oral administration of the extract at a dose of 200 and 400 mg/kg. Blood glucose level was decreased by 50% in alloxan-induced diabetic rats within three weeks of daily treatment of Thuja occidentalis methanolic residue extract (200 and 400 mg/kg p.o). Alloxan-induced diabetic rats showed significant hypercholesterolemia in comparison with the control in alloxan induced rats. Results: In both normal and diabetic rats, there was also a significant decrease of elevated serum cholesterol and triglycerides. Hypertriglyceridemia was also shown to be prevented by treatment with plant extract (200 and 400mg/kg p.o) (p<0. 05). As compared with the control animals, diabetic control rats did not show any change in a level of creatinine and urea. Conclusion: Thuja occidentalis treatment may improve glucose homeostasis in alloxaninduced diabetes and alleviate kidney and liver function. Thuja occidentalis twigs could be a potential source of the new oral antidiabetic drug.
