Herbal plants represent a new source of hypoglycemic antidiabetic drugs; haematological and histopathological studies of methanol extract of Deverra tortuosa in streptozotocin-induced diabetic rats were investigated in vivo. A single intraperitoneal injection of 160 mg/kg bodyweights of streptozotocin was used to cause diabetes. Blood glucose levels were tested with an AccuCheck Advantage II glucometer and blood glucose test strips. After diabetes was confirmed, animals were orally treated with the extract, metformin, and insulin according to the experimental design. After extract therapy, histological alterations in the pancreas of diabetic rats were investigated. When compared to a control group, daily oral administration of D. tortuosa extract (300 mg/kg body weight) plus metformin (100 mg/kg) had a positive effect on blood glucose levels as well as showed an increased number of white blood cells (WBCs) and red blood cells (RBCs). The treatment with the extract for two weeks showed a positive impact on pancreatic histopathological changes in the groups with the diabetic rats. Phenolic fraction of the methanol extract was screened by the liquid chromatography-mass spectroscopy (LC-MS) method, which unveiled the existence of flavonoid compounds and phenolics as kaempferol, rutin, isorhamnetin-3-O-rutinoside, caffeic acid, and 4-hydroxybenzoic acid 4-O-glucoside. The results confirmed the use of the plant as an antidiabetic agent; the research recommended further studies on the plant to use the plant as an antidiabetic drug, where the plant extract also showed improvement in blood parameters.

  Objective: This study was conducted to scientifically evaluate the antidiabetic and antioxidant effects of ethanolic leaf extract of Erythrina abbysinica (EEA).Methods: Acute and sub-chronic effects of EEA at 100, 200, and 400 mg/kg/bwt and glibenclamide (GL) at 5 mg/kg/bwt. were evaluated in both normal and streptozotocin (STZ)-induced diabetic male Wistar rats (250–300 g). The acute studies were performed using oral glucose tolerance test (OGTT). In sub-chronic studies, animals were orally administered with EEA and GL daily for 6 w. Brine shrimp assay was used to determine the toxicity of EEA. 1, 1-diphenyl-2-picrylhydrazyl, ferric reducing capacity of plasma, and thiobarbituric acid reactive substances assays were used to determine antioxidant properties of EEA.Results: Following OGTT, EEA significantly (p<0.05) and dose-dependently (100, 200, and 400 mg/kg/bwt) decreased blood glucose levels in both normal and STZ-induced diabetic rats when compared with positive and negative control counterparts at all-time points, whereas GL significantly (p<0.05) decreased blood glucose only in normal rats but not in diabetic rats. Daily, oral administration of EEA for 6 w significantly (p<0.05) and dose-dependently (100, 200, and 400 mg/kg/bwt) decreased blood glucose levels in STZ-induced diabetic rats when compared with the diabetic control group. EEA revealed weak toxicity with a lethal concentration50 value of 997 μg/ml). Furthermore, EEA showed significant free radical scavenging, total antioxidant, and anti-lipid peroxidative capacities.Conclusion: The study has shed more light on the scientific basis for the use of E. abbysinica in management of diabetes in some communities of Eastern Cape of South Africa.

To evaluate the effect of telmisartan on blood glucose levels and blood lipid levels in streptozotocin induced diabetic rats. Eighteen Wistar albino rats weighing 150-200gms of either sex were randomly selected from the central animal facility, and divided into 3 groups. Diabetes was induced by injecting Streptozotocin intraperitonelly. The control group received 1% Gum acacia (oral), standard group received 0.5 mg/kg Glibenclamide (oral) and the test group received Telmisartan 7.2mg/kg body weight (oral) from 0-28 days respectively. Body weight of the individual rats were measured on the respective days before blood glucose estimation on 0, 1, 3, 7, 14, 21 & 28th day and fasting blood glucose was estimated by (ACCUCHECK) glucometer. Estimation of fasting lipid profile by lipid screening strips on 1st and 28th day. When compared to control the capillary blood glucose (CBG) levels in the Telmisartan group was less at all the intervals but comparable with that of standard drug Glibenclamide in Streptozotocin induced diabetic rats. Improved lipid profile was seen with the Telmisartan group when compared to control group in Streptozotocin induced diabetic rats. Hypoglycemic activity and improved lipid profile action was seen with Telmisartan group which is comparable to standard drug glibenclamide in streptozotocin induced diabetic albino rats.

Background:: Terebinthus atlanticus (Anacardiaceae) is an important source of essential oil and phenolic compounds justifying its use in traditional medicine. Objective:: The present work aimed to evaluate the antidiabetic and the antioxidant activities of the aqueous extract of the leaves of Terebinthus atlanticus (T. atlanticus). Methods:: The current study evaluated the effect of a single and repeated (15 days of treatment) oral administration of the aqueous extract of the leaves of T. atlanticus (PALAE) on blood glucose levels in normal and streptozotocin(STZ)-induced diabetic rats. Furthermore, the effect of PALAE on glucose tolerance and histopathological examination of the liver was carried out. Results:: A single oral administration of PALAE reduced blood glucose levels in normal (p<0.05), and STZ diabetic rats (p<0.0001), 6 and 4 hours after administration, respectively. Furthermore, this extract had an optimal effect (p<0.0001) in both normal and STZ diabetic rats at the 15th and 7th day of treatment. This extract was also shown to prevent significantly the increase on blood glucose levels 120 min after glucose administration, in both normal (p<0.05), and diabetic (p<0.01) treated rats when compared to the control group. In addition, the histopathological analysis highlighted the positive effect of T. atlanticus on pancreas and liver. Conclusion:: The study demonstrates the antihyperglycemic effect of the aqueous T. atlanticus extracts in diabetic rats which should be mediated through the amelioration of the oxidative stress as well as an improvement in liver histology.

The objective of the present study was to evaluateα-glucosidase inhibitory and antidiabetic effects of Nopal water extract (NPWE) and Nopal dry power (NADP) in low-dose streptozotocin- (STZ-) induced diabetic rats fed a high-fat diet (HFD). The type 2 diabetic rat model was induced by HFD and low-dose STZ. The rats were divided into four groups as follows: (1) nondiabetic rats fed a regular diet (RD-Control); (2) low-dose STZ-induced diabetic rats fed HFD (HF-STZ-Control); (3) low-dose STZ-induced diabetic rats fed HFD and supplemented with NPWE (100 mg/kg body weight, HF-STZ-NPWE); and (4) low-dose STZ-induced diabetic rats fed HFD and supplemented with comparison medication (rosiglitazone, 10 mg/kg, body weight, HF-STZ-Rosiglitazone). In results, NPWE and NADP had IC50values of 67.33 and 86.68 μg/mL, both of which exhibit inhibitory activities but lower than that of acarbose (38.05 μg/mL) while NPWE group significantly decreased blood glucose levels compared to control and NPDP group on glucose tolerance in the high-fat diet fed rats model (P<0.05). Also, the blood glucose levels of HR-STZ-NPWE group were significantly lower (P<0.05) than HR-STZ-Control group on low-dose STZ-induced diabetic rats fed HFD. Based on these findings, we suggested that NPWE could be considered for the prevention and/or treatment of blood glucose and a potential use as a dietary supplement.

.The main purpose of present study was to perform phytochemical screening and explore the anti-hyperglycaemic properties of Alangium salvifolium root extract in normal and alloxan induced diabetic rats. A. salvifolium root gave maximum extractive values of 6.4 % w/w with Ethanol and other parameters were within limits. The extract gave positive tests for phytosterols, triterpenes, flavonoids, carbohydrates and alkaloids. The ethanolic extract of A. salvifolium was found to be nearly as potent as tolbutamide in decreasing the blood glucose levels in normal fasting rats. In normal control group the percent reduction in blood glucose indicated that the extract is fast acting. The extract showed significant decrease in blood glucose, when compared with tolbutamide. The evaluated blood glucose levels in alloxan induced diabetic rats were significantly decreased up to 24th h compared to tolbutamide. A single oral administration of alcoholic extract at doses 100, 250 and 500 mg per kg produced a significant blood glucose reduction in a dose dependent manner in normal and diabetic rats. These data confirm the hypoglycaemic and anti-hyperglycaemic effect of alcoholic extract of A. salvifolium root in normal and diabetic rats respectively when compared with standard drug tolbutamide.Keywords: Alangium salvifolium; Ethanolic extract; Alloxan induced; Hypoglycaemic action.© 2011 JSR Publications.

Eriobotrya japonica locally called as loquat in Kashmir has been studied in various parts of the world but little work has been reported on Kashmiri loquat. The chemical nature of fruits and vegetables offers a great diversity of biological properties and plays an important role in the field of pharmacology. There is a quest for newer drugs with few adverse effects and this poses a challenge for the development of new drugs. The study was undertaken to study the activities of ethanolic extract of Eriobotrya japonica fruits in streptozotocin induced diabetic rats. The phytochemical screening of the plant was also done. The animals were divided into five groups. Normal Control group received only the vehicle. Toxic group included those animals in which diabetes was induced by streptozotocin. The 3rd group was those animals which received streptozotocin and standard antidiabetic drug-glibenclamide. 4th group included those diabetic animals which received 50 mg/kg b.w dose of fruits of Eriobotrya japonica. 5th group animals included those diabetic animals which received 100 mg/kg b.w of the plant extract. The biochemical parameters that were evaluated were blood glucose levels and lipid profile tests. The body weight was also checked. Histopathology of pancreas was also done. The results showed significant decrease in blood glucose levels, lipid profile tests in animals treated with different doses of the plant extracts. Histopathology of pancreas also showed positive results.

Background: Medicinal plants are now becoming indispensable in the treatment and management of many ailments. The unaffordability, unavailability and adverse effects of conventional therapy in the treatment and management of many diseases have geared keen interest in the use of herbal medicine. This work was carried out to investigate the prophylactic effect of the ethanol extract of Azadirachta indica leaf in streptozotocin-induced diabetic rats.   Methods: A total of one hundred (100) rats were randomized into four (4) groups (n=25) and used for the study. Each group of 25 rats was sub-divided into five (5) groups (n=5). The sub-groups comprise: Group A-normal control that was not treated, group B-100 mg/kg body weight of metformin and groups C to E - graded doses (100 mg/kg, 200 mg/kg and 400 mg/kg body weight) of the ethanol leaf extracts of A. indica leaves. The standard drug and the extracts were consecutively administered to groups B-E for 7, 14, 21 and 28 days before the induction of diabetes. Diabetes was induced intraperitoneally using 50 mg/kg bodyweight of streptozotocin. Results: The groups that were administered 100, 200 and 400 mg/kg bw of ethanol extract of A. indica showed a significant (p<0.05) increase in their weight after 21 and 28 days of pre-treatment compared with the control group that was not treated. The graded doses of the extract also have a remarkable effect in the fasting blood glucose levels which was made visible by the significant (p<0.05) reduction recorded in the fasting blood glucose levels compared with the control group that was not pre-treated and the group pre-treated with metformin. Conclusion: The results obtained in this research suggest that ethanol extract of A. indica has the potential to protect against diabetes by delaying its onset. However, the longer the period of pre-treatment, the better the condition of the animals pre-treated as well as the protection as can be seen from the results of the weight and fasting blood glucose levels.

Alhagi maurorum(camel thorn plant) is a promising medicinal plant due to the presence of flavonoids and phenolic compounds as major contents of its constituents. No previous study has been conducted before onA. maurorum extractsas an antioxidative stress and/or antidiabetic herb in STZ-induced DM in rats. Therefore, four groups of rats were allocated as control (C), STZ-induced DM (D), and STZ-induced DM supplemented with 300 mg/kg BW of either aqueous extract (WE) or ethanolic extract (EE) ofA. maurorum. The plasma levels of glucose, TG, TC, LDL-C and VLDL-C, MDA, and bilirubin and the activities of transaminases and GR were significantly increased in the diabetic group. Also, diabetic rats showed severe glucose intolerance and histopathological changes in their livers. In addition, levels of insulin, total proteins, GSH, and HDL-C and the activities of SOD, GPx, and GST were significantly decreased in the diabetic rats compared to those of the control group. The ingestion ofA. maurorumextracts lowered the blood glucose levels during the OGTT compared to the diabetic rats and restored all tested parameters to their normal levels with the exception of insulin level that could not be restored. It is concluded thatA. maurorumextracts decreased elevated blood glucose levels and hyperlipidemia and suppressed oxidative stress caused by diabetes mellitus in rats.

Background: Diabetes mellitus is known to cause cognitive impairment that can be possibly attributed to deficient levels of leptin in diabetic animals. This study was undertaken to study the effect of administration of leptin on spatial learning, memory and blood glucose levels in diabetic rats.Methods: Rats were divided into three groups. The first group was the control group. Diabetes was induced in groups 2 and 3 by streptozotocin (STZ) injection (60 mg/kg) intraperitoneally. Group 2 received saline while group 3 received leptin (0.1 mg/kg) subcutaneously for 10 days from 4th day of STZ administration. Behavioural assessment was done in T maze after 21 days of the last injection of leptin. Blood glucose levels were also analysed.Results: The number of correct arm entries decreased while time spent being immobile and time spent to reach the correct arm increased in the diabetic group when compared to the control group and correct arm entries increased while time spent immobile and time spent to reach the correct arm decreased with leptin treatment when compared to the diabetic control rats. Blood glucose levels increased in the diabetic rats while leptin administration reduced blood glucose levels in the group 3.Conclusions: Our study suggests that leptin can improve learning and memory while also producing a slight reduction in the blood glucose levels in diabetic rats.
