Purpose: Phytochemicals present in vegetables has been associated with the health potentials of leafy vegetables. Diabetes has been implicated with increased oxidative stress leading to alteration of haematological parameters among other complications. This study investigated the phytochemicals, antinutrients and toxicants contents of methanol extracts of Hibiscus cannabinus, Adansonia digitata, Sesamum indicum and Cassia tora leaves and compared the effect of their leaves extract on some haematological parameters of alloxan – induced diabetic rats using standard methods of analysis.Methodology: Fifty-five (55) male albino rats weighing 120 – 150g divided into 11 groups of five rats each were used.  One diabetic untreated rat group, one diabetic group treated with standard drug ,8 diabetic groups treated with graded doses of the vegetable extracts and one normal group as control. All the groups received water and feed ad libitum together with their various treatments for 23 days. At the end of the experiment, blood was taken from the rats for determination of PCV, Hb, WBC, and RBC. ANOVA was used to separate the means of all the data collected with significance at p< 0.05 using Statistical Package for Scientist and Engineers (SPSE) version 9.1.Results: Results showed reasonable levels of phytochemicals, antinutrient and toxicants levels within WHO safe limits. Results of animal studies showed that administration of 500mg of Hibiscus cannabinus leaf extract increased the PCV, HB, WBC and RBC of diabetic rats more than all the other vegetable extracts (p<0.05). It also improved the WBC and RBC better than standard drug. This shows that Hibiscus cannabinus leaf extract might improve some haematological parameters associated with diabetes mellitus, however its inhibitory effect on higher dose raised concern for further investigation.Unique contribution to theory, practice and policy: Hibiscus cannabinus leaf extract could be used in the dietary management of haematological abnormalities associated with the pathophysiology of diabetes mellitus by health care systems

Diabetes mellitus develops either due to insufficient insulin secretion or lack of insulin resulting from damaged pancreas beta cells. Dyslipidaemia is an acute complication in diabetes mellitus. The aim of this study was to investigate the extenuating effects of T. cattapa leaves and P. americana seed aqueous extracts on streptozotocin-induced lipids profile perturbation and pancreatic damage in experimental rats. Thirty male albino rats were randomly divided into six groups (n = 5). Group 1: (negative control), group 2: 80 mg/kgbwt streptozotocin (positive control), group 3: (80 mg/kgbwt streptozotocin + 200 mg/kgbwt T. catappa leave extract), group 4: (80 mg/kgbwt streptozotocin + 200 mg/kgbwt Persea americana seed extract), group 5: (80 mg/kgbwt streptozotocin + 200 mg/kgbwt extracts-mixture), group 6: (80 mg/kgbwt streptozotocin + 5 mg/kgbwt glibenclamide (standard drug). A single dose of streptozotocin was administered to the rats intraperitoneally; the extracts and glibenclamide were administered orally for 21 days, after which their pancreas was excised for histology. Thereafter, extracts of T. catappa leaves and P. americana seed on serum lipid levels imbalance in streptozotocin-induced diabetic rats were investigated. Histological studies showed a degenerative effect of the pancreatic islet cells of strotozotocin-induced groups. Results showed improvement in the regulation of lipid metabolism as well as the regeneration of the beta cells of pancreas on treatment with T. catappa leaves and P. americana seed. The extracts both equally exert significant antidyslipidemic effects in diabetic rats, in view of the extenuating effects of the extracts on pancreatic islet cells.

Traditional Chinese medication has been utilized by Chinese medical practitioners to treat the varied symptoms of diabetes mellitus (DM). Notably, guava leaf has been used to treat diabetes in Asia. Our present study has been designed to analyze the action of guava leaf extract (GLE) at the molecular level in treating DM. A low dose of streptozotocin (STZ) was used to induce experimental diabetes in animals. Rats were treated with GLE at different concentrations (100, 200, and 400 mg/kg b.w.). The standard drug glibenclamide (GB) (600 μg/kg b.w.) was used for comparison. The diabetic rats showed a reduced level of insulin, accompanied by exaggerated levels of blood glucose, lipid peroxidation product, and augmented expressions of inflammatory cytokines, and showed reduced levels of antioxidants compared to the control rats. Supplementation with GLE counteracted the consequences of STZ. It suppresses the oxidative stress and inhibits the state of inflammation and the results are almost similar to that of standard drug group (GB group 5). Our present research, therefore, provides useful data concerning guava leaf extract by a thorough assessment in diabetes management. Being a natural product, additional analysis on GLE can shed light on finding effective phytochemicals within the field of diabetes mellitus.

Background: There is a growing interest in the correlation between antioxidants and periodontal disease. In this study, we aimed to investigate the effect of oxidative stress and the impact of two antioxidants, curcumin and rutin, respectively, in the etiopathology of experimentally induced periodontitis in diabetic rats. Methods: Fifty Wistar albino rats were randomly divided into five groups and were induced with diabetes mellitus and periodontitis: (1) (CONTROL)—control group, (2) (DPP)—experimentally induced diabetes mellitus and periodontitis, (3) (DPC)—experimentally induced diabetes mellitus and periodontitis treated with curcumin (C), (4) (DPR)—experimentally induced diabetes mellitus and periodontitis treated with rutin (R) and (5) (DPCR)—experimentally induced diabetes mellitus and periodontitis treated with C and R. We evaluated malondialdehyde (MDA) as a biomarker of oxidative stress and reduced glutathione (GSH), oxidized glutathione (GSSG), GSH/GSSG and catalase (CAT) as biomarkers of the antioxidant capacity in blood harvested from the animals we tested. The MDA levels and CAT activities were also evaluated in the gingival tissue. Results: The control group effect was statistically significantly different from any other groups, regardless of whether or not the treatment was applied. There was also a significant difference between the untreated group and the three treatment groups for variables MDA, GSH, GSSG, GSH/GSSG and CAT. There was no significant difference in the mean effect for the MDA, GSH, GSSG, GSH/GSSG and CAT variables in the treated groups of rats with curcumin, rutin and the combination of curcumin and rutin. Conclusions: The oral administration of curcumin and rutin, single or combined, could reduce the oxidative stress and enhance the antioxidant status in hyperglycemic periodontitis rats.

Currently, cardiovascular diseases are the leading cause of global mortality, while diabetes mellitus remains an important cause of cardiovascular morbidity. A recent study showed that patients with diabetes mellitus treated with mineralocorticoid receptor antagonists have improved coronary microvascular function, leading to improved diastolic dysfunction. In this study, we evaluated the influence of acute administration of spironolactone on myocardial function in rats with streptozotocin-induced diabetes mellitus, with special emphasis on cardiodynamic parameters in diabetic rat hearts. The present study was carried out on 40 adult male Wistar albino rats (8 weeks old). Rats were randomly divided into 4 groups (10 animals per group): healthy rats treated with 0.1 μmol/L of spironolactone, diabetic rats treated with 0.1 μmol/L of spironolactone, healthy rats treated with 3 μmol/L of spironolactone, and diabetic rats treated with 3 μmol/L of spironolactone. Different, dose-dependent, acute responses of spironolactone treatment on isolated, working diabetic and healthy rat heart were observed in our study. In healthy rats, better systolic function was achieved with higher spironolactone dose, while in diabetic rats, similar effects of low and high spironolactone dose were observed.

Aim: To evaluate the nephroprotective property of Cnidoscolus chayamansa aqueous leaf extract in diabetic rats. Study Design: Rats were randomly divided into five groups with group 1 as the normal control. Diabetic was induced in groups 2-4. Group 2 was used as the test control while groups 3 and 4 were treated with different concentrations of the leaf extract; group 5 was treated with the standard drug, glipizide. Place and Duration of Study: Departments of Biochemistry and Anatomy, University of Jos, Nigeria, between August to November, 2019. Methodology: Fourty (40) male albino Wistar rats were grouped into five groups. The rats were treated for fourteen days and then sacrificed by decapitation after anaesthesia. Blood was collected for biochemical parameters; kidney was excised and stored in formaldehyde until required for histopathological study. Serum urea, creatinine, uric acid, sodium, potassium, chloride and bicarbonate were determined using appropriate methods. Results: The test control had a significant (P < .05) decrease in the concentrations of Na+, Cl- and HCO3- ions; significant (P < .05) increases in serum K+ ion, urea, uric acid and creatinine. Treatments of the test groups with the different doses of the leaf extract and the standard drug increased the concentration of Na+ ion which was not significantly (P < .05) different from the test control. On the other hand, the concentration of Cl- and HCO- ions  were significantly (P < .05) increased; the concentrations of K+, urea, uric acid and creatinine were significantly (P < .05) decreased. The histochemistry of the kidneys revealed that the injury brought about under diabetic condition was ameliorated with the treatments with the low and high doses of the leaf extract, and the standard drug. Conclusion: The results show that the aqueous leaf extract has nephroprotective property.
