Objective: In this research, we evaluated the antihyperglycemic effect of leaves of Fumaria parviflora (F. parviflora) and implied mechanisms by using in vivo models of hyperglycemia. Materials and Methods: Fifty male Wistar rats weighing 180-220 g were applied for the research. Soxhlet ethanolic extract of leaves of F. parviflora (EFP ) was prepared. Alloxan-induced diabetic rats were orally remedied with the extract (50, 100 or 200 mg/kg/day), metformin (200 mg/kg/day) for two weeks. Another animal received only extract, alloxan (diabetic control) or vehicle (control). Results:  pretreatment effect of plant extract on blood glucose levels of diabetic rats Blood glucose levels in all extract pretreated groups was lower (p<0.05) when compared with the levels in rats that received alloxan alone, Rats that we are treated with plant extract had normal blood glucose levels that ranged for 73.00±1.5 to76.00±0.54 mg/dl at the beginning (first day) of experiment. Blood glucose levels in these animals declined during the period of extract administration, but the values obtained were not significant compared to control excluded those that were obtained on the 14th day, p < 0.05 Conclusion: Leaves of F. parviflora possess blood glucose-lowering effects  In Alloxan-Induced Diabetic  Rat, The findings of a study indicated that F. parviflora has a significant hypoglycemic effect on Alloxan-induced diabetic rats with no effects in blood glucose levels of normal rats.

AbstractBackgroundDiabetes is the one of the leading cause of morbidity and mortality. Traditionally phytotherapy is widely being used for diabetes treatment and highly valued. Citrus colocynthis has known anti-diabetic potential. However, anti-diabetic potential of hydro-ethanolic extract of C. colocynthis pulpy flesh with seeds is not reported yet.MethodsThe extract of C. colocynthis pulpy flesh with seeds was done by maceration method using 70% ethanol. To evaluate anti-diabetic and antioxidant potential of the seeded fruit in vitro, α-glucosidase and DPPH inhibition assays was done, respectively. In vivo study used streptozotocin (STZ) induced diabetes model of rats. Rats were randomized in five groups i. e. normal control, negative control, standard control, C. colocynthis 150 and 300 mg/kg. STZ was administered to all groups except normal control. After wards, plant extract and glibenclamide is continued for 14 days. Blood samples were collected from rat tail vein daily and from Cardiac puncture at the end of study. The blood glucose levels were monitored daily by using one-touch blood glucose monitoring system. The blood glucose level was monitored on 0, 1st, 5th, 8th, 11th, and 14th day of induction.ResultsHydro-ethanolic extract of C. colocynthis pulpy flesh with seeds was able to decolorize DPPH and therefore possess antioxidant potential, continuous administration for 14 days showed a marked decrease in serum glucose levels (p 0.01) it is found to be somewhat less effective as glibenclamide (standard control) (p 0.001). A time-dependent decrease in blood glucose levels was observed (351.3 ± 4 to 258 m/kg).ConclusionHydro-ethanolic extract of C. colocynthis pulpy flesh with seeds lowered the serum triglyceride and cholesterol levels in diabetic rats significantly as compared to negative control. The hypoglycemic effect of hydro-ethanolic extract of C. colocynthis pulpy flesh with seeds is may be due to α-glucosidase inhibition potential.

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.

Aims: The aim of the study was to assess the antihyperglycemic activity of Brassica oleracea. Background: Collard green or Brassica oleracea var. viridis which belongs to Brassicaceae family is ranked at 10th place of “powerhouse” vegetables, and it is commonly used traditionally for the treatment of diabetes in Morocco. Objective: This current investigation aimed to assess the antihyperglycemic capacity of the aqueous extract of Collard green leaves. Methods: The effect of a single (6 hours) and repeated (seven days of treatment) oral administration of Collard green aqueous extract (CGAE) at a dose of 60 mg/kg on glucose and lipid profile was examined in normal and streptozotocin-induced diabetic rats. Additionally, histopathological examination of liver was carried out according to the Hematoxylin-Eosin method. Furthermore, a preliminary phytochemical screening, and the quantification of phenolic, flavonoid and tannins contents as well as the antioxidant activity using DPPH assay were carried out. Results: The results demonstrated that Collard green A.E. (CGAE) exhibited a significant antihyperglycemic effect and positive improvement liver histology in diabetic rats. After a single oral administration of CGAE, blood glucose levels were lowered from 15±2 mM to 4.9±1 mM (p<0.0001) at the sixth hour in diabetic rats but no change was observed in normal rats. Repeated CGAE administration was able to reduce blood glucose levels from 15±2 mM to normal values (5±1 mM at the seventh day, p<0.0001) while the extract had no effect in normal rats. In addition, we revealed that CGAE is rich in several phytochemical compounds and exerts an important antioxidant activity. Conclusion: In conclusion, this study demonstrates that Collard green possesses a beneficial effect against diabetes, and can be used in the program diet of diabetic patients.

Aims: The current study was carried out in order to assess the antihyperglycemic effect of Scorzonera undulata (S. undulata). Backgroud: Scorzonera undulata subsp. deliciosa (DC.) Maire is used in the Moroccan pharmacopeia for managing diabetes. Objective: The objective of the study was to evaluate the anithyperglycemic activity in normal and streptozotocin (STZ)- induced diabetic rats as well as the acute toxicity of the aqueous extract of the roots of Scorzonera undulata (S. undulata). Methods: This study investigated the effects of the root aqueous extract of Scorzonera undulata (AERSU) at a dose of 20 mg/kg on blood glucose levels in normal and streptozotocin(STZ)-induced diabetic rats and the acute toxicity of AERSU was examined. Histopathological examination, preliminary phytochemical investigation, determination of glycogen content and evaluation of α-amylase were also performed. Result: Both single and repeated oral doses of AERSU (20 mg/kg) produced a significant reduction of blood glucose levels in normal and diabetic rats. Furthermore, repeated oral administration of AERSU during 15 days increased the glycogen content in the liver in both normal and diabetic rats, inhibited α-amylase activity and improved the histological architecture of the liver and pancreas in treated diabetic rats and ameliorated some biochemical parameters such as ALT and AST. In addition, the preliminary phytochemical investigation showed the richness of the roots of S. undulata in certain phytochemicals particularly in polyphenols. Conclusion: AERSU exhibits an evident antihyperglycemic activity. This pharmacological effect may be due at least to protection of surviving pancreatic β cells, to the protection of hepatocytes, to α-amylase inhibitory effect and to the improvement of glycogen storage in the liver. The dose used in this study seems to be free of any toxicity.

Background. Type 1 diabetes mellitus results from autoimmune destruction ofβ-cells. Insulin-producing cells (IPCs) differentiated from mesenchymal stem cells (MSCs) in human tissues decrease blood glucose levels and improve survival in diabetic rats. We compared the differential ability and the curative effect of IPCs from three types of human tissue to determine the ideal source of cell therapy for diabetes.Methods. We induced MSCs from Wharton’s jelly (WJ), bone marrow (BM), and surgically resected pancreatic tissue to differentiate into IPCs. Thein vitrodifferential function of these IPCs was compared by insulin-to-DNA ratios and C-peptide levels after glucose challenge.In vivocurative effects of IPCs transplanted into diabetic rats were monitored by weekly blood glucose measurement.Results. WJ-MSCs showed better proliferation and differentiation potential than pancreatic MSCs and BM-MSCs.In vivo, WJ-IPCs significantly reduced blood glucose levels at first week after transplantation and maintained significant decrease till week 8. BM-IPCs reduced blood glucose levels at first week but gradually increased since week 3. In resected pancreas-IPCs group, blood glucose levels were significantly reduced till two weeks after transplantation and gradually increased since week 4.Conclusion. WJ-MSCs are the most promising stem cell source forβ-cell regeneration in diabetes treatment.

It has been previously shown that oral magnesium administration decreases the levels of glucose in the plasma. However, the mechanisms are not fully understood. The aim of this study was to determine the potential role of GLUT4 on plasma glucose levels by orally administering magnesium sulfate to diabetic rats. Animals were distributed among 4 groups (n = 10 rats per group): one group served as the non-diabetic control, while the other groups had diabetes induced by streptozotocin (intraperitoneal (i.p.) injection). The diabetic rats were either given insulin by i.p. injection (2.5 U·(kg body mass)–1·day–1), or magnesium sulfate in their drinking water (10 g·L–1). After 8 weeks of treatment, we conducted an i.p. glucose tolerance test (IPGTT), measured blood glucose and plasma magnesium levels, and performed in-vitro and in-vivo insulin level measurements by radioimmunoassay. Gastrocnemius (leg) muscles were isolated for the measurement of GLU4 mRNA expression using real-time PCR. Administration of magnesium sulfate improved IPGTT and lowered blood glucose levels almost to the normal range. However, the insulin levels were not changed in either of the in-vitro or in-vivo studies. The expression of GLU4 mRNA increased 23% and 10% in diabetic magnesium-treated and insulin-treated groups, respectively. Our findings suggest that magnesium lowers blood glucose levels via increased GLU4 mRNA expression, independent to insulin secretion.

.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.
