Aims: This study was aimed at investigating the antihyperglycemic effect of a combined extract of Vernonia amygdalina and croton zabensicus compare with a hypoglycemic drug, glibenclamide. Methodology: Twenty 20 experimental animals were used (albino rats); the rats were divided equally into four groups of five rats each; namely A (control), B (glibenclamide 10 mg/kg body weight), C (synergetic treatment 1000 mg/kg body weight), D (synergetic treatment 500 mg/kg of body weight). Diabetes was induced intraperitoneal using Alloxan Monohydrate to all the animals and their blood glucose rise above 200 mg/dl. Results: It was observed that group B and group C treated with glibenclamide (10 mg/kg body weight) and synergetic aqueous extract (1000 mg/kg body weight) show significant decrease in the blood glucose level from 451.75 mg/dl to 64.50 mg/dl and 339.50 mg/dl to 182.50 mg/dl respectively compared with group D with 278.25 mg/dl to 194.75 mg/dl. However, a change was also observed in the body weight of the groups; Group A (Normal control) showed a continuous increase in the body weight, Group B, C and D were observed to have decreased in body weight from induction period, but a steady increase was observed as treatment commences. Conclusion: Hence this combined extract can be used as antihyperglycemic; only that it is slower in remediation compared with the glibenclamide; but without side effect, as may be in the case of most standard drug.

The use of herbs in the management of diabetes mellitus and its complications have been reported. This study was thus aimed at determining the levels of some biochemical parameters in streptozotocin-induced diabetic albino rats pre-treated and post-treated with Vernonia amygdalina and Gongronema latifolium extracts. Fifty (50) albino rats weighing between 150 – 250 g were used for this study. 25 albino rats were used for each phase of the treatment. The pre-treatment phase involved the treatment of the rats with 400 mg/kg b.w (singly) and 200 mg/kg b.w (combined) extracts for 14 days, after which diabetes mellitus was induced using streptozotocin before the rats were sacrificed. The post-treatment phase involved the inducement of diabetes with streptozotocin after which the rats were treated with 400 mg/kg b.w (singly) and 200 mg/kg b.w (combined) extracts for 28 days before the animals were sacrificed. Blood was collected via cardiac puncture and plasma/serum was collected. Total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), malondialdehyde (MDA), and total antioxidant capacity (TAC) were determined using standard procedures while glucose was measured with a glucometer. Cardiovascular risk ratios such as Castelli risk ratio I and II and atherogenic index of plasma were also calculated. Results showed that extracts of V. amygdalina (only), G. latifolium (only) and V.A+ GL (combined)significantly (p<0.05) reduced the TC, LDL-C , FBS, MDA and TAC levels while HDL-C level significantly (p<0.05) increased. The cardiac risk indices (CRI-I and CRI-II, and Atherogenic index of plasma (AIP) in both the pre-treated and post-treated rats were also reduced when compared to diabetic control. It is thus evident that these plants’ extracts possess hypoglycaemic, hypolipidaemic, and antioxidant properties and thus could be used to reduce cardiovascular risks. Therefore, the tradomedicinal use of these plants in the management of cardiovascular complications is highly recommended.

Aim: The study evaluated the effects of the combined extracts of Vernonia amygdalina (VA) and Gongronema latifolium (GL) on pancreatic GLUT 2 expression and caspase 3 activity in streptozotocin (STZ, 45 mg/Kg)-induced diabetic rats. Study Design: Fifteen Albino rats were used for the study and were placed in 3 groups of 5 rats each: A - normal control, B – Diabetic control and C – experimental group. Place and Duration of Study: The study was carried out in the department of Anatomy, University of Calabar. Duration:  6 months. Methodology:  Half of the diabetic rats were treated with VA+GL (400mg/kg, ratio 1:1, DE group) for 28 days, while the other half was untreated and served as diabetic control (DC). Normal control (NC) rats were untreated. After 28 days, the rats were sacrificed and their blood glucose, serum GLUT 2 and caspase 3 activity were measured.  Histochemical evaluation of the pancreas was also carried out. Results: Blood glucose concentrations for the 3 groups were 60.31±7.28, 257.00±4.43, and 116.60±10.11 mg/dl for NC, DC and DE respectively. This represented a 4-fold increase in the DC compared with NC and a significant amelioration in the extract-treated DE group compared with DC group. Serum GLUT 2 concentrations were 70 ng/ml in NC, dropped to 8 ng/ml (p<0.05) in the DC and recovered to 20 ng/ml in DE (p<0.05). Serum caspase was 3.2 ng/ml for NC, increased to 8.5 ng/ml in DC (p<0.05) and reduced to 1.8 ng/ml in DE (p<0.05). The histology of the pancreas showed distorted, degenerated and shrunken β-cells mass in DC compared with NC and DE groups. The DE group showed clear signs of regeneration of the islet cells which was corroborated by positive Feulgen’s reaction compared with the DC group. Conclusion: The data suggests that the combined VA+GL extract has the potential to effectively reverse pancreatic damage in diabetes.
