Objective: The aim of this work was to evaluate the antihyperglycemic activity of aerial parts aqueous extract (A.P.A.E) of Mentha pulegium (M. pulegium) on blood glucose levels in normal and streptozotocin(STZ)-induced diabetic rat. The glucose tolerance was evaluated in normal rats. Moreover, the histological sections and morphometric analysis at the liver and pancreas have been carried out in this investigation both in normal and STZ-diabetic rats. Methods: The effect of A.P.A.E of M. pulegium (20 mg/kg) on blood glucose levels was investigated in normal and diabetic rats (n=6). Histopathological changes in liver and pancreas were examined under phase contrast microscope and a preliminary screening for various bioactive constituents was realized according to standard methods. Key Findings: Both single and repeated oral administration of A.P.A.E (20 mg/kg) caused a significant reduction in blood glucose levels in STZ-diabetic rats (p<0.0001). The morphometric analysis and histological sections realized in pancreas and liver have showed the beneficial effect of the A.P.A.E in cellular population. According to oral glucose tolerance test (OGTT), the aqueous extract has revealed an improvement of glucose tolerance in normal rat. Furthermore, the preliminary phytochemical screening of A.P.A.E of M. pulegium has demonstrated the presence of various metabolite compounds including polyphenols, flavonoids, terpenoids tannins, cyanidins, sesquiterpenes, and glycosides. Conclusion: We conclude that the A.P.A.E of M. pulegium (20 mg/kg) exhibits a potent antihyperglycemic activity in STZ diabetic rats.

Aim and objective: Clerodendrum thomsoniae leaves are used in Cameroon to manage diabetes and its related disorders. The study aimed at investigating the antidiabetic effect of the aqueous extract on diet and dexamethasone induced diabetic rats. Methods: Young mature leaves of C thomsoniae were dried, finely powdered and submitted to aqueous extraction. The dehydrated extract was tested in rats at 3 doses 312.5, 625 and 1250 mg/kg based on the local use of the plant. The effect of the extract on the fasting blood glucose in normoglycemic rats and MACAPOS 1 type diet induced diabetic rats, using respectively glibenclamide and metformin as positive control groups, were investigated. Results: AECT significantly reduced blood glucose levels in normoglycemic rats (p<0.05) two hours after administration, from 83±2 mg/dL to 57.39±1.7 mg/dL with the dose of 1250 mg/kg. given the highest reduction rate of 30.86%. In normoglycemic rats 30 minutes after oral glucose overload, the maximum reduction rate was observed with glibenclamide 5 mg / kg and calculated at 49.90% followed by 36.39%, for the extract at 1250 mg / kg. After 30 days of repeated oral administration, AECT produced a reduction on blood glucose levels (p<0.05) in type 2 diabetic rats. This reduction in blood sugar was much more expressed with the dose of 1250mg/kg (73.52±0.71 mg/dL) followed by metformin 38mg/kg (70.21±0.89 mg/dL) as the normal control with no significant difference (P < 0.05). Conclusion: These results show that the antidiabetic activity of AECT can be explained by insulin stimulating effect, also give support to the traditional use of this plant.                   Peer Review History: Received 11 May 2021; Revised 17 June; Accepted 27 June, Available online 15 July 2021 Academic Editor: Dr. Asia Selman Abdullah,  Al-Razi university, Department of Pharmacy, Yemen, [email protected] UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

Characterised by abnormal increase in blood glucose level, Diabetes is a metabolic disorder that is associated with complications in carbohydrate, protein and fat metabolism. In recent times, medicinal herbs have been implicated in traditional medical practice for the treatment of this ailment. Studies have shown that Buchholzia coriacea seed possesses some anti-hyperglycemic properties that may be useful in the management of diabetes. To this point, present study investigated the effect(s) of oral administration of aqueous and ethanol extracts of Buchholzia coriacea on some carbohydrate metabolism parameters in normal and alloxan-induced diabetic rats. Forty (40) adult rats of both sexes were randomly assigned into two groups (normoglycemic and hyperglycemic). While group 1 (normoglycemic) had normal control, metformin, aqueous extract (250mg/kg) and ethanol extract (250 mg/kg) treated sub-groups respectively, Group 2 (hyperglycemic) contained the diabetic control, metformin, aqueous extract (250 mg/kg), and ethanol extracted (250mg/kg) treated sub-groups dosed daily by oral gavage for 14 days. At the end of the treatment, rats were euthanized via cervical dislocation; blood samples were collected by cardiac puncture for statistical analysis. One-way analysis of variance (ANOVA) revealed that dosing with extracts had insignificant effect(s) on body weight of rats. Fasting Blood Glucose (FBG) levels were elevated before and after extracts administration. Metformin, aqueous and ethanol extracts significantly reduced (p<0.05) FBG levels. Also, compared with control, total carbohydrate, liver glucose, glycosylated haemoglobin, Lactate Dehydrogenase, Isocitrate dehydrogenase, MDH, SDH, 6-phosphogluconate dehydrogenase, G6PD and CcO activities were significantly reduced (p<0.05) in diabetic treated rats. Buccholzia Coriacea was therefore seen to pose hypoglycemic and glycolytic effects, regulating activities of carbohydrate metabolic enzymes. Apparently, there is a scientific merit in the use of the extract in the management of diabetes.

Introduction: This study examined the antihyperglycemic effect of curry leaves, Murraya koenigii “MK” aqueous extract, and to examine its possible protective effects on the Islets of Langerhans and kidneys in streptozotocin (STZ) induced diabetic rats.  Methods: Thirty healthy adult male Sprague Dawley rats were randomized into five groups (n=6); normal control, normal treated with “MK” control, diabetic control (non-treated with “MK”), diabetic treated with 200mg/kg MK aqueous leaf extract and diabetic treated with 400mg/kg MK aqueous leaf extract. Blood glucose levels and body weight were monitored. The animals were sacrificed on the 30th day; the kidney and pancreatic tissues were processed for histological studies. Results: The diabetic control group significantly (p<0.001) showed considerable loss of body weight and increase in blood glucose levels and degeneration of the glomeruli and renal convoluted tubules and atrophied islets with disintegration of β-cells. Treatment of diabetic rats with aqueous extract showed significant (p<0.001) improvement in blood glucose levels and body weight gain.  The MK extract also caused an improvement in tissue injury induced by STZ injection in the kidney and endocrine pancreas.  Conclusions: These findings highlighted the beneficial effects of MK aqueous extract against cellular oxidative damage in STZ-induced diabetic rats.

Background: Diabetes mellitus is associated with high blood glucose levels due to insulin shortcoming (insulinopenia) or defective insulin action. The objective of the study was to investigate the antidiabetic and antioxidant effects of Foeniculum vulgare in streptozotocin-induced diabetic rat. Methods: The effects of the leaves aqueous extract (LAE) of Foeniculum vulgare (F. vulgare) at a dose of 10 mg/kg on blood glucose levels were evaluated in normal and streptozotocin (STZ)- induced diabetic rats. Histopathological changes were also evaluated in liver in STZ-induced rats. Results: Single oral administration of F. vulgare LAE reduced blood glucose levels 6 h after administration in STZ diabetic rats (p<0.0001). Furthermore, blood glucose levels were decreased in both normal (p<0.05) and STZ diabetic rats (p<0.0001) after the fifteenth day of treatment. During this test, both groups did not show any significant change in their body weight. Moreover, this aqueous extract improved oral glucose tolerance in diabetic rats and revealed a positive effect on liver histology. On the other hand, the extract used in this experiment showed an inhibitory concentration (IC50) of 50% of free radicals with a concentration of 43±1.19 µg/ml. While the synthetic antioxidant (BHT) had an IC50 equal to 22.67±2.17µg /ml. Conclusion: This study demonstrates the antihyperglycemic, hypoglycemic and antioxidant effects of the leaves of F. vulgare in normal and diabetic rats.
