This study investigated the effects of methanol extract of Cussonia arborea on serum lipid and oxidative stress biomarkers of alloxan-induced diabetic rats. A total of 72 male albino rats assigned into 6 groups of 12 rats per group were used. Groups 1-5 were made diabetic while group 6 were normal. Groups 1-4 were treated with 62.5, 125, 250 mg/kg of the extract and 2 mg/kg glibenclamide respectively while groups 5 and 6 received 10 ml/kg distilled water each. Total cholesterol, triglyceride, high density lipoprotein (HDL), malondiadehyde, catalase, and superoxide dismutase (SOD) were assayed on days 28, 56 and 84 post treatment. The results indicated that the extract significantly (p<0.05) reduced the levels of total cholesterol, triglyceride, malondialdehyde but significantly (p<0.05) increased the activities of SOD, catalase and the levels of HDL when compared to negative control. It was therefore concluded that methanol extract of C. arborea mitigated dyslipidaemia and oxidative stress.

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.

Bridelia atroviridis Müll. Arg. (B. atroviridis) is a plant used in Cameroonian traditional medicine to manage diabetes. The effects of hydroethanolic barks extract from B. atroviridis were evaluated on diabetes disorders including hematology, inflammatory, and oxidative stress parameters. The in vitro antioxidant capacity of the hydroethanolic bark extract (70 : 30) was evaluated. Nicotinamide-/streptozotocin-induced diabetic rats were daily treated with the B. atroviridis extract for fifteen days. Glycemia were evaluated every 5 days, insulin sensibility test was performed, and haematological, inflammatory, and oxidative stress parameters were analysed. Histomorphometry of the pancreas was realized. The extract was able to scavenge free radicals in vitro and decrease significantly the blood glucose levels. The treatment resulted in a significant alleviation of insulin resistance, anemia, leukocytopenia, and thrombocytopenia observed in untreated diabetic rats. The extract significantly decreased proinflammatory cytokines TNF-α, IL-1β, and IL-10. The rate of reduced glutathione was increased in the pancreas, whereas the catalase activity and nitrite concentration were decreased. Diabetic control showed a reduced size of Langerhans islet, whereas the size of islets was large in treated groups. The hydroethanolic extract of B. atroviridis was able to improve glycemia and alleviate haematological and inflammatory parameters disorders observed in diabetic conditions, probably due to its antidiabetic, anti-inflammatory, and antioxidant capacities.

Objective: Diabetes mellitus (DM) and hypercholesterolemia (HC) when poorly controlled lead to debilitating central nervous system complications including cognitive deficits and memory impairment. In the present study, we investigated the mechanisms that may be responsible for such deficits. Methods: Both diabetes and HC were induced in two groups of rats independently using alloxan and high cholesterol diet, respectively. Results: Acetyl cholinesterase was significantly increased in brain of diabetic rats. Also, brain malondialdehyde level was extremely elevated in both diabetic and hypercholesterolemic groups. Meanwhile, brain albumin was markedly decreased in both of them. However, the brain iron level was significantly increased in DM with concomitant increase in total antioxidant capacity in the same group as compared to the normal control. The concentration of brain calcium was noticeably increased in HC group. Our results were confirmed by the increased activity of lactate dehydrogenase in both DM and HC groups, indicating major brain cytotoxicity. Conclusions: Overall, our results suggested that both DM and HC have deleterious effects on the brain which may be attributed to oxidative stress and dysregulation of both cholinergic function and calcium level. Administration of antioxidant is recommended in both cases.

Diabetes is one of the leading diseases worldwide and, thus, finding new therapeutic alternatives is essential. The development of non-alcoholic fatty liver disease is a notable diabetic complication. Therefore, antioxidant therapy became a leading topic in the world of diabetes research. The objective of this present study was to evaluate the effects of antioxidant N-acetylcysteine (NAC) administration on serum biochemical parameters and oxidative stress parameters in hepatic tissue of the diabetic rats. Thirty-two animals were divided in 4 groups (n = 8): G1, normal rats; G2, normal rats + NAC; G3, diabetic rats; and G4, diabetic rats + NAC. Diabetes was induced in diabetic groups through streptozotocin. NAC administration was effective in improving hyperglycemia and hypoinsulinemia, as well as reducing serum alanine-aminotransferase and urea, hepatic triglycerides accumulation, and oxidative stress biomarkers in the diabetic liver, as well as improving the activity of hepatic antioxidant enzymes. This effect was likely due to NAC’s ability of restoring intracellular glutathione, an important compound for the antioxidant defense, as well as due to NAC’s direct antioxidant properties. Thus, NAC administration was useful for reducing hepatic oxidative stress and decreased the deposit of triacylglycerols, minimizing diabetic hepatic damage, making it a promising therapeutic adjuvant in the future.
