Background: The use of plants known to possess significant antioxidant activities have been widely recommended in the complementary and alternate system of medicine in the treatment of diabetes mellitus. Among the many plant used in Nigeria for the management of DM are Vernonia amygdalina and Ficus exasperata. This study was designed to assess the effect of the combination of the aqueous extract of Vernonia amygdalina and Ficus exasperata on blood glucose level, lipid profile, hepatic enzymes, lipid peroxidation and antioxidant status in alloxan-induced diabetes in rats. Method: Twenty five rats were divided into five groups. Four groups were made diabetic by the intra-peritoneal administration of alloxan monohydrate (150mg/kg body weight) while the fifth group served as normal control. Serum, hepatic and renal concentrations of reduced glutathione (GSH) and thiobarbituric acid reactive substances (TBARS) as well as the catalase activity were determined. The blood lipid profile and some hepatic enzymes were also studied. Result: The combined extract lowered lipid peroxidation, increase glutathione concentration and catalase activity in all the tissues of diabetic rats. The individual extract lowered the total cholesterol LDL-Cholesterol, coronary risk index (CRI), and atherogenic index (AI) while increasing the concentration of HDL cholesterol in alloxan-induced diabetic rats. Diabetes lowered hepatic enzymes’ activities but the leaf extract significantly increased it. Conclusion: It can be concluded that combination of the extracts showed additive effect on each other and it is highly recommended for the management of diabetes.

This work investigates the ability of Morinda lucida and co-administration of Morinda lucida/metformin in the control of biochemical and histological changes in alloxan-induced diabetic rats. Alloxan diabetic rats were treated with 200 mg/Kg body weight of Morinda lucida leaves extract, 1 mg/Kg BW of metformin or a combination of the two treatments for 28 days. Results of the studies revealed that Morinda lucida leaves extract significantly improved lipid profile and kidney function in diabetic rats. These positive outcomes were enhanced by combined treated with Morinda lucida leaves extract and metformin. Furthermore, the calculated atherogenic index of treated animals were close to those of normal rats as opposed to diabetic rats. Similarly, histological studies showed that Morinda lucida leaves extract and metformin administered together or singly, ameliorated damages in pancreas and kidneys from alloxan diabetic rats. It can therefore be inferred that combined treatment with Morinda lucida leaves extract and merformin could improve the potency of Morinda lucida leaves used in the management of diabetic complications

Rats fed a galactose-rich diet have been used for several years as a model for diabetes to study, particularly in the eye, the effects of excess blood hexoses. This study sought to determine the utility of galactosemia as a model for oxidative stress in extraocular tissues by examining biomarkers of oxidative stress in galactose-fed rats and experimentally-induced diabetic rats. Sprague-Dawley rats were divided into four groups: experimental control; streptozotocin-induced diabetic; insulin-treated diabetic; and galactose-fed. The rats were maintained on these regimens for 30 days, at which point the activities of catalase, glutathione peroxidase, glutathione reductase, and superoxide dismutase, as well as levels of lipid peroxidation and reduced and oxidized glutathione were determined in heart, liver, and kidney. This study indicates that while there are some similarities between galactosemic and diabetic rats in these measured indices of oxidative stress (hepatic catalase activity levels and hepatic and renal levels of oxidized glutathione in both diabetic and galactosemic rats were significantly decreased when compared to normal), overall the galactosemic rat model is not closely parallel to the diabetic rat model in extra-ocular tissues. In addition, several effects of diabetes (increased hepatic glutathione peroxidase activity, increased superoxide dismutase activity in kidney and heart, decreased renal and increased cardiac catalase activity) were not mimicked in galactosemic rats, and glutathione concentration in both liver and heart was affected in opposite ways in diabetic rats and galactose- fed rats. Insulin treatment reversed/prevented the activity changes in renal and cardiac superoxide dismutase, renal and cardiac catalase, and hepatic glutathione peroxidase as well as the hepatic changes in lipid peroxidation and reduced and oxidized glutathione, and the increase in cardiac glutathione. Thus, prudence should be exercised in the use of experimentally galactosemic rats as a model for diabetes until the correspondence of the models has been more fully characterized.

Streptozotocin Induced Diabetes

Diabetes mellitus is a non-communicable disease which has been associated with liver and kidney injuries, and at the same time affects lipid profiles. The aim of this study was to investigate the role of Vernonia amygdalina (VAM) on plasma lipid profile, liver and kidney enzymes in rats with streptozotocin -induced diabetes. Twenty-five male albino wistar rats weighing between 137 and 223 g were randomly grouped into five of five rats per group as follows: control, diabetic, diabetic + metformin (MET), diabetic + VAM at 150, 300 mg/kg. Diabetes was induced by administration of 45 mg/kg body weight streptozotocin (STZ) dissolved in citrate buffer (0.01 M, pH 4.5) by single intraperitoneal injection. Three days after, when diabetes was confirmed, MET and VAM were administered daily by oral gavage for 7 days. Animals were fasted overnight after the last administration of MET and VAM, sacrificed, blood was collected and plasma prepared for lipid profile estimation. Liver and kidney were collected, weighed, homogenized and supernatants obtained for enzymes and biochemical assays. There were no significant (p>0.05) change in the weights of animal, liver and kidney, liver/rat and kidney/rat ratios, plasma cholesterol (CHOL) concentration, activities of liver and kidney aspartate aminotransferase (AST), alanine aminotransferase (ALT), liver gamma-glutamyl transferase (GGT), lactate dehydrogenase (LDH), and liver and kidney total protein (TPRO) concentrations; significant (p<0.05) decrease in triglyceride (TRIG), high density lipoprotein-cholesterol (HDL), low density lipoprotein-cholesterol (LDL), very low density lipoprotein-cholesterol (VLDL); and significant (p<0.05) increase in fasting blood glucose (FBG) level, kidney GGT, LDH activities, liver and kidney creatinine (CREA) and total bilirubin (TBIL) concentrations of diabetic (STZ) rats compared with normal control. The treatment of the diabetic rats with MET and VAM significantly modulated positively these parameters compared with the diabetic rats. This study further explains the protective role played by VAM in dyslipidaemia, liver and kidney injuries resulting from diabetes.

Abstract Context Trigonella foenum-graecum (TriFG) exhibits increased scavenger enzymatic activities and reduces the production of reactive oxygen species in diabetic rats. Objective The present study was aimed to investigate the effect of TriFG on lipid peroxidation levels and antioxidant status in brain tissue of rats exposed to alloxan. Materials and Methods Healthy male rats (180 ± 10 g) were allocated into five groups. Animals in group 1 maintained on normal tap water served as controls and rats in groups 2, 3, 4, and 5 were treated as experimental groups. Rats in group 2 were intraperitoneally injected with alloxan (120 mg/kg BW) and treated as diabetic rats, whereas rats in groups 3 and 4 were maintained on same experimental regimen as that of rats in groups 1 and 2, respectively, and in addition, they were orally gavaged with herbal extracts of TriFG (0.25 g/kg BW). Diabetic rats treated with glibenclamide in group 5 were used as positive controls. Results and Discussion Significant (P &lt; 0.001) increase in the antioxidant enzymes with a significant (P &lt; 0.001) decrease in the lipid peroxidation levels were observed in the brain tissue of diabetic rats treated with TriFG extract as compared to diabetic and glibenclamide-treated rats. No significant changes were observed in pro- and antioxidant levels in brain tissue of rats treated with TriFG extract alone when compared to normal rats. In diabetic rats, brain mitochondrial and cytosolic enzymes like succinate dehydrogenase, glutamate dehydrogenase, and glucose-6-phosphate dehydrogenase activity levels were significantly (P &lt; 0.05) decreased with reversely increased was observed in lactate dehydrogenase activity (P &lt; 0.05). Conclusions The findings of the present study suggested that TriFG, through its antioxidant properties, protects brain tissue by mitigating oxidative stress induced by alloxan-exposed rats. TriFG extract significantly increased the antioxidant and oxidative properties in diabetic rats when compared with the control group rats.

Background. Type 1 diabetes mellitus (T1DM) is characterized by insulin-deficient production leading to hyperglycemia, which is associated with diabetic complications such as cardiovascular diseases. Antioxidants have been proving a good alternative to diabetic complications, with N-acetylcysteine (NAC) having antioxidant characteristics. The aim of this study was to assess the effect of NAC on the lipid profile and the atherogenic index (AI) in streptozotocin- (STZ-) induced diabetic rats.Method. 32 male Wistar rats (60 days of age) weighting ±250 g were randomly distributed into four groups (n=8): CTRL: control rats; CTRL+NAC: control rats treated with NAC; DM: diabetic rats; DM+NAC: diabetic rats treated with NAC. T1DM was induced using STZ (60 mg/kg, ip; single dose), and NAC (25 mg/kg/day) was administrated by gavage, for 37 days. The animals received chow and waterad libitum. After the experimental period, blood and cardiac tissue samples were collected to analyze energetic metabolism, lipid profile, and AI.Results. NAC decreased (p<0.01) glycemia, energy intake, carbohydrate, and protein consumption in diabetic rats (DM+NAC), when compared with DM, while the alimentary efficiency was improved (p<0.01) in treated diabetic rats (DM+NAC). Diabetic rats treated with NAC decreased (p<0.01) lipid profile and AI in diabetic rats (DM+NAC) when compared to DM.Conclusion. NAC improves lipid profile and decreases AI in STZ-induced diabetic rats.

Lipid Index

Stroke was associated with morbidity and mortality in the world. Lipid index discovered through lipid profile tests may be used as a predictor in vascular diseases. To increase the prediction value of lipid profile to stroke outcome, several lipoprotein ratios, called atherogenic index, were still being researched. Atherogenic indexes included Atherogenic index of plasma, Castelli Risk Index I and II, atherogenic coefficient, and non-high density lipoprotein cholesterol. The aim of this study is to find atherogenic index profile as a marker for atherogenicity on acute ischemic stroke patients at Neurology Department Dr. Soetomo hospital from January-September 2019. This is a retrospective descriptive of 65 patients on stroke registry. Data collected including low and high AIP level on 19, 46 patients, respectively; low CRI I on 22 patients and high CRI I on 43 patients; low CRI II from 31 patients and high CRI II from 34 patients; low and high AC on 9 and 56 patients, respectively; also, low NHC on 21 patients and high NHC on 44 patients. Poor outcome on outpatient was identified in 30 patients (NIHSS >7). This study indicates most ischemic stroke patients have high atherogenic index level. Analysis on the differences between lipid index and NIHSS poor outcome revealed AC and NHC level were significant with p = 0,031, CI 8,593 (1,007 – 73,319) and p = 0,01, CI 9,529 (2,435 – 37,3), respectively.

Background: Polyphenols represent a group of bioactive compounds of interest for their efficacy in the prevention and treatment of some diseases of a cardiovascular nature. Calafate (Berberis microphylla) is a native Chilean fruit, promising due to its high number of phenolic compounds, with predominance of anthocyanins delphinidin-3-hexoside and petunidin-3-hexoside.  Methods: Sprague Dawley rats fed a high-fat diet (HFD) were supplemented with 350 mg/kg of freeze-dried calafate for 10 weeks. Dietary variables, plasma glucose, lipid profile, as well as atherogenic and cardiovascular risk indexes were measured.  Results: Animals receiving calafate with their HFD diet compared to the HFD control was not associated with significant modifications in dietary variables or in total cholesterol and triglyceride concentrations. However, due to the modest elevation of high-density lipoproteins, the Atherogenic Index and the Cardiovascular Risk Index were significantly decreased.  Conclusion: Based on these results, the calafate could have an antithrombotic function, favoring cardiovascular health. Keywords: High-fat diet, polyphenols, calafate berry, HDL-cholesterol, Atherogenic Index

Introduction: Diazinon (DZN) administration produces lipid peroxidation as an indicator of oxidative stress in the brain. Some medicinal plants such as Dorema glabrum has antioxidant properties, so can be used as an antioxidant that may protect neurons from oxidative stress. The aim of present study was to investigate the effect of D. glabrum against DZN-induced oxidative stress in hippocampus. Methods: Twenty-four adult male Wistar rats were used in this study. The rats randomly were divided into four groups including a control group, and two groups received different doses of D. glabrum (40 and 80 mg/kg) as pre-treatment for 21 days with DZN (100 mg/Kg) that was injected intraperitoneally (ip) in last day of D. glabrum usage, and one group received only DZN. Thiobarbituric acid reactive substances (TBARS), which are the indicators of lipid peroxidation, and the activities of antioxidant enzymes (glutathione peroxidase, superoxide dismutase and catalase) were determined in the ratsʼ hippocampus. Results: Administration of DZN significantly increased TBARS levels and superoxide dismutase activity and decreased glutathione peroxidase activity but there were no significant changes in catalase activity in the hippocampus. Combined D. glabrum and DZN treatment, caused a significant increase in glutathione peroxidase, a significant decrease of TBARS and a significant decrease in superoxide dismutase and again no significant changes in catalase activity in the rats’ hippocampus when compared to the rats treated with DZN. Conclusion: Our study demonstrated that D. glabrum had an amelioratory effect on oxidative stress induced by DZN.

This study aimed to evaluate the effects of the treatment with bacuri seed butter (BB) on body weight, growth, body mass index, lipid profile, atherosclerotic indices, and liver function in dyslipidemic hamsters. Freshly weaned, male hamsters were divided into four groups: (1) normal group (NG)—maintained with standard chow (AIN-93G); (2) dyslipidemia group (DG)—maintained with hyperlipidemic chow (AIN-93G modified) throughout the follow-up period; (3) bacuri seed butter 25 mg/kg/day (BB-25); and (4) bacuri seed butter 50 mg/kg/day (BB-50). BB groups (25 and 50 mg/kg/day) were also maintained with hyperlipidemic chow throughout the follow-up period, and the treatment started after 21 days receiving a hyperlipidemic diet to induce hypercholesterolemia and maintained for 28 days. No significant differences in triglycerides and total cholesterol were observed for BB-25 and BB-50 groups when compared with NG and DG groups. On the contrary, BB-25 and BB-50 induced both increase of HDL-c (51.40 ± 1.69 and 51.00 ± 2.34, respectively) and decrease of LDL-c (103.80 ± 6.87 and 100.50 ± 3.95, respectively) when compared with DG (41.00 ± 2.94 and 132.70 ± 9.41, respectively). In addition, BB promoted a reduction in the risk of atherosclerotic disease by decreasing p < 0.05 the atherogenic index, coronary artery risk index, and LDL/CT ratio p < 0.05 and increasing HDL/CT ratio. On the contrary, no changes were observed in total cholesterol and triglyceride levels or in body weight, growth, body mass index, or liver function parameters. Thus, bacuri seed butter at doses of 25 and 50 mg/kg/day has positive repercussions on the lipid profile, more precisely on plasma HDL-c and LDL-c, and additionally promotes reduction in the risk of atherosclerosis in hamsters.
