Studies on biochemical effects of aqueous extract of Carica papaya leaf on alloxan-induced diabetic albino rats were undertaken. One hundred albino rats of Wistar strain were obtained and divided into five groups of twenty rats each and properly treated with the aqueous extract after four out of the five groups were induced with diabetes. The diabetic induced groups were diabetic control, test groups I (treated with 200 mg/kg) and II (treated with 50 mg/kg), and reference (treated with the standard glibenclamide). The diabetic free group was designated as normal control. Results obtained revealed that oral administration of aqueous extract of C. papaya leaf on alloxan-induced diabetic albino rats significantly reversed the damage associated with alloxan-induced diabetes revealing its hypoglycemic, liver and renal function integrity effects. The presence of phytochemicals and phytonutrients found in C. papaya could explain the observed pharmacological property of the studied extract. This study has revealed the biochemical effects of aqueous extract of C. papaya leaf on alloxan-induced diabetic albino rats.

Antioxidant Effects

Annona muricata, an herbal plant commonly used in traditional medicine to manage numerous diseases, diabetes as other diseases could be managed with herbal medicine. This study was designed to be investigated the antidiabetic, hypolipidemic, renal protective, and antioxidant effects of aqueous extracts of Annona muricata as used alone or combined with metformin in streptozotocin (STZ)-induced diabetic rats. Methods: the study was involved twenty adult Wister albino rats in four groups (five rats in each) and designated as groups, control group (1), and experimental groups (2, 3, 4). Diabetes was induced in experimental groups by 60 mg/kg intravenous streptozotocin injection. Group 2: serves as a diabetic control group, Group 3: diabetic rats treated with oral administration of 100 mg/kg of Annona muricata aqueous extract, Group 4: diabetic rats treated with combination (100 mg/kg aqueous extract of Annona muricata + 50 mg/kg metformin). The treatment continuous daily for 4 weeks to determine the levels of blood glucose and biochemical analysis. Result: aqueous extract of Annona muricata was reduced the serum glucose level effectively in streptozotocin-induced diabetic rats, by 48% and 55% after 28 consecutive days of treatment when used alone and with metformin, respectively. These compared to the preliminary values and the reduction was statistically significant compared to a diabetic control group. Daily oral administration of 100 mg/kg aqueous extract of Annona muricata for 4 weeks to streptozotocin-induced diabetic rats significantly reduced the level of total cholesterol, urea, creatinine, and MDA, whereas the reduction was non-significant in triglyceride and VLDL-cholesterol levels as compared to the non-treated diabetic group. However, the reduction is more significant in streptozotocin-induced diabetes rats that were treated with a combination of Annona muricata and metformin when compared to the diabetic control group. Conclusion: Aqueous extracts of Annona muricata have anti-diabetic action through their hypoglycemic, hypolipidemic, renal protective, and antioxidant effects in streptozotocin-induced diabetic rats. Thus, can be used alone or with anti-hyperglycemic drugs as metformin in the management of DM. The combination is preferred in severe hyperglycemic cases with more hypoglycemic effect requirements.

Aim: Diabetes mellitus (DM) is a prevalent metabolic disorder that leads to other microvascular and macrovascular complications. Diabetes affects fertility and blood clotting, and also cause impaired lipid profile thus leading to increased atherogenic risks and coronary diseases. This research investigates the effects of Carica papaya leaf methanol extract on fertility indices and lipid profile of male diabetic rats. Methodology: Male Wistar albino rats were randomly divided into five groups of six rats each. Diabetes was induced in the rats by a single intraperitoneal injection of streptozotocin (55 mg/kg). Diabetic rats were treated orally with 100 and 200 mg/kg C. papaya methanol extract for 14 days. At the end of administration, the plasma glucose concentration and lipid profile were assayed by spectrophotometric methods; seminal analysis was carried out for evaluation of morphology, motility and sperm count under the microscope. The bleeding and clotting times of the rats were also determined. Results: C. papaya leaf methanol extract caused significant (p = 0.05) reduction in plasma glucose, total cholesterol, triglycerides, VLDL-C, LDL-C, bleeding and clotting times of diabetic treated rats, while the HDL-C of treated groups were significantly (p = 0.05) elevated compared to the diabetic control. Percentage normal cells were lower in diabetic control rats (41.4±4.4%) and C. papaya treated groups (50.0±8.5% for 100 mg/kg; 47.5±9.1% for 200 mg/kg) compared with the normal control group (69.5±5.6%). Similar results were recorded for sperm count. The qualitative phytochemical screening showed the presence of steroids, anthraquinone, tannin, and other bioactive compounds. Conclusion: findings from this study indicated that C. papaya leaf methanol extract could possess hypoglycemic and hypolipidemic activities. Thus, could be considered as a potential source of bio pharmacological agent for management and control of DM and its complications. Prolonged administration of C. papaya leaves may negatively affect male fertility.
