Diabetes Induction

Background: Diabetes mellitus is a group of metabolic disorders which result to excessive accumulation of blood sugar over a prolonged period. Due to higher risk of diabetes mellitus to cardiovascular disease, it is crucial to identify and address these cardiovascular risks. This study assessed the effects of diabetes on levels of some blood lipids and its atherogenic indices in diabetic male rats. Methods: This is an experimental study that involved 40 apparently healthy adult male albino rats (wistar strain) which were randomly assigned to five groups (A, B, C, D and E) of eight (8) animals each. Group A (Normal Control of No intervention for 72 hours), Group B (Diabetic rats of 72 hours post diabetes induction), Group C (metformin treated diabetic rats), Group D (Diabetic Control untreated) and Group E (Normal Control of 3 weeks post diabetes induction). Seven milliliters of fasting blood sample were collected from all the subjects. Serum levels of total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-c), low density lipoprotein cholesterol (LDL-c) and very low density lipoprotein cholesterol (VLDL-c) were determined using standard methods. Atherogenic indices, non HDL cholesterol (Non HDL-c), cardio risk ratio (CRR), atherogenic index of plasma (AIP), atherogenic coefficient (AC) and atherosclerosis index (AI) were calculated. It was analyzed statistically using SPSS version 23.0. Results: The mean values of HDL-c was significantly higher in the treated diabetic group when compared with untreated diabetic control (P<0.05) while TC, TG, LDL-c, VLDL-c, Non HDL-c, CRR, AIP, AC and AI were significantly lower in treated diabetics when compared to the untreated diabetic control (P<0.05). Also, blood mean levels of HDL-c were significantly lower in the diabetic groups (treated and untreated) when compared with non diabetic control (P<0.05) while TC, TG, LDL-c, VLDL-c, Non HDL-c, CRR, AIP, AC and AI were significantly higher in the diabetic groups (treated and untreated) when compared with non diabetic control (P<0.05). Conclusion: The study suggests that atherogenic indices can serve as predictive pointer for future cardiovascular event especially, when LDLc value is normal. Also hyperglycemia could cause significant alterations of lipids, but metformin treatment has showed not only hypoglycemic effect, but also anti-hyperlipidemic properties.

Objective: To evaluate the antioxidant and antihyperlipidaemic effect of methanol extracts of Asteracantha longifolia and Pergularia daemia leaf in alloxan induced diabetic rats. Methods: Swiss albino rats were made diabetic by a single dose of alloxan monohydrate (150 mg/kg i.p.). Blood glucose levels and body weights of rats were measured using on weekly intervals i.e day 0,7,14 and 21 after daily administration of both extracts at dose 200 mg/kg bw. Other biochemical parameters such as serum cholesterol, triglycerides, low density lipoprotein-cholesterol, very low density lipoprotein-cholesterol, high density lipoprotein-cholesterol, phospholipids and serum protein, albumin, globulin levels were also measured at the end of study. The antioxidant enzymes (CAT, SOD & GSH) were also measured in the diabetic rats. Results: In the acute toxicity study, methanol extract of both plants were non-toxic at 2000 mg/kg in rats. The increased body weight, decreased blood glucose and other biochemical parameters level were observed in diabetic rats treated with methanol extracts of both plants compared to diabetic control rats. The antioxidant activity of both plant extracts were also exhibited significant activity. In diabetic rats, methanol extract of both plants administration, altered lipid profiles were reversed to near normal than diabetic control rats. Conclusions: Methanol extract of both plants (Asteracantha longifolia and Pergularia daemia) leaf possesses significant antioxidant and antihyperlipidaemic activity in diabetic rats.

Rutin, a food derived-polyphenolic bioflavonoid, has been acknowledged for several health benefits. This study aims to explore the ameliorative effects of rutin against carbon tetrachloride (CCl4) toxicity in male rats. Adult male rats were given either CCl4 (30% in olive oil, 3 ml/kg b.w. intraperitoneally) alone or in combination with rutin (70 mg/kg intragastrically) twice a week for 4 weeks. Our data showed that rutin mitigated CCl4 hepatorenal damage, as indicated by diagnostic markers (i.e., transaminases, alkaline phosphatase, total bilirubin, total protein, albumin, urea, uric acid and creatinine), and histopathological findings. In addition, CCl4 induced profound elevation of free radical generation and oxidative stress, as evidenced by increasing lipid peroxidation and reducing catalase, superoxide dismutase and glutathione peroxidase activities in liver, kidney and testicular tissues; these effects were suppressed by coexposure with rutin. Moreover, the increase in the levels of serum triglycerides, cholesterol, low-density lipoprotein cholesterol, and very-low-density lipoprotein cholesterol induced by CCl4 was effectively counteracted by rutin. The decrease in the level of high-density lipoprotein cholesterol in the CCl4 group was also counteracted by rutin treatment. Interestingly, the decreased levels of hormonal mediators associated with sperm production, including serum testosterone, luteinizing hormone and follicle-stimulating hormone, and the impaired sperm quality induced by CCl4 were reversed by rutin. Data from the current study clearly demonstrated that rutin supplementation could at least partly overcome CCl4-induced hepatotoxicity, nephrotoxicity and reproductive toxicity by antioxidant and antidyslipidemic effects.

The separate and joint effects of cigarette smoking and alcohol consumption on serum concentrations of total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and triglycerides were investigated in 46 750 men attending the BUPA Health Screening Centre in London during the period 1983–1987, after allowing for differences in age, body mass index and exercise level. Drinking alcohol was found to raise both total cholesterol and HDL-C concentrations, in such a way that HDL-C as a percentage of total cholesterol increased with increasing alcohol consumption. LDL-C concentrations increased with increasing alcohol consumption in non-smokers, but decreased in those smoking over 10 cigarettes per day. Drinking had no significant effect on triglycerides except at high levels of consumption. Smoking raised total cholesterol, LDL-C and triglycerides, but lowered HDL-C concentrations. In particular, smoking even small amounts could negate any protective benefit in HDL-C concentrations gained from moderate consumption of alcohol. Assuming a desirable lipid profile to consist of low total cholesterol, LDL-C and triglycerides and a high HDL-C value, this is best achieved for men by being a non-smoking moderate drinker.

Abstract Background: To explore the temporal relationship between blood lipids and sleep duration and clarify their potential causality in Chinese middle-aged and elderly individuals.Methods: We used medical examinations and questionnaire data of 5016 Chinese middle-aged and elderly individuals in 2011 and 2015. Cross-lagged path analysis was performed to examine the potential bidirectional relationships between blood lipids and sleep duration.Results: In total population, significant bidirectional relationship was observed between sleep duration and high-density lipoprotein cholesterol level and the path coefficients were -0.171 (P = 0.005) and -0.006 (P = 0.002). In contrast, there was a positive correlation between and sleep duration, and the path coefficient from triglycerides to sleep duration 4 year later (O = 0.001, P = 0.018) was greater than that from sleep duration to triglycerides 4 year later (b = 0.109, P = 0.847), with P = 0.030 for the difference between j and e. Longer sleep duration was associated lower levels of low-density lipoprotein cholesterol (c = -0.275, P = 0.097) and total cholesterol (t = -0.329, P = 0.096) 4 year later. In stratified analysis, effects of sleep duration on blood lipids were only observed among individuals aged < 60 years, while the effect in the opposite direction was observed in elderly individuals, and the cross-lagged path coefficients were more significant in adults with BMI > 25.Conclusions: Temporal relationships between sleep duration and high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, total cholesterol, and triglycerides were different. The strength and direction of the relationships may be related to age and BMI.

Background:Research studies that holistically investigated the effect of administration of Virgin Coconut Oil (VCO) on diabetic humans or animals are limited in literature.Objective:To investigate the effect of administration of VCO on lipid profile, markers of hepatic and renal dysfunction, and hepatic and renal antioxidant activities of alloxan induced diabetic rats.Methods:Twenty-four male albino rats were used, and they were divided into four groups of six rats each. Group 1 (Normal Control, NC) received distilled water (1 mL/kg); Group 2 (VCO Control) received VCO (5 mL/kg); Group 3 (Diabetic Control, DC) received distilled water (1 mL/kg); Group 4 (Test Group, TG) received 5 ml/kg of VCO.Results:There were no significant differences in blood glucose, body weights, relative liver weights, relative kidney weights, hepatic and renal Superoxide Dismutase (SOD) activities, Malondialdehyde (MDA), albumin, aspartate Amino Transaminase (AST), alanine Amino Transaminase (ALT), Alkaline Phosphatase (ALP), urea, creatinine, uric acid, total cholesterol, triacylglycerol, Very Low Density Lipoprotein cholesterol (VLDL) and Low Density Lipoprotein cholesterol (LDL) concentrations; significant increases in renal Glutathione (GSH), hepatic catalase, Glutathione Peroxidase (GPx) and GSH but significant reduction in renal GPx and catalase activities of VCO control group compared with NC group. There were significant increases in blood glucose, relative liver and kidney weights, hepatic GPx, hepatic and renal MDA concentration, ALP, AST, ALT, urea, creatinine, uric acid, triacylglycerol, total cholesterol, LDL and VLDL concentrations; and significant decreases in body weight, hepatic SOD and GSH activities and albumin concentration but no significant difference in hepatic catalase activity of DC group compared with NC group. Administration of VCO to diabetic rats positively modulated these parameters compared with the diabetic control.Conclusion:The study showed the potentials of VCO in the management of hyperlipidemia, renal and hepatic dysfunctions imposed by hyperglycemia and by oxidative stress in diabetic rats.

The current study was carried out to determine the hypoglycemic and hypolipidemic activities of methanolic extract P. silhetensis leaves in alloxan-induced diabetic rats. In this study diabetes was induced in rats by intraperitoneal administration of 150 mg/kg of alloxan. Animals were treated for one week with the plant extract at doses of 250 and 500 mg/kg body weight. Metformin (100 mg/kg b.w.) was used as standard for comparison. The anti-diabetes activity was examined by measuring blood glucose level at 0, 3, 5 and 7 days in diabetic induced animal models. Blood samples were collected at day eight of the treatment and analyzed for triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) after sacrifice. Alloxan-induced diabetic rats exhibited a significant decrease in plasma glucose level when treated with P. silhetensis leaf extract as compared to normal, diabetic control and standard rats. All tested lipid parameters were improved after the treatment with methanolic extract of P. silhetensis and metformin as compared to diabetic rats. The results of the present study showed that P. silhetensis possesses significant anti-diabetic properties and has beneficial effects on diabetic hyperlipidemia.

AbstractCardiovascular disease (CVD) risk factors, and particularly decreased high density lipoprotein cholesterol (HDL-C) dyslipidemia are prevalent in Assam, India. This study was undertaken to investigate whetherApolipoprotein A-I(APOA1) gene polymorphisms (G-75A and C+83T) were associated withi) the risk for decreased HDL-C, andii) other CVD risk factors,viz. serum lipids, atherogenic indices, obesity, and blood pressure (BP). A total of 649 subjects were screened, from which 200 eligible individuals, classified as case group with decreased HDL-C levels (100 subjects) and control group with normal HDL-C levels (100 subjects) were enrolled and genotyped using polymersase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and DNA sequencing. Lipid fractions [HDL-C, total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), very low density lipoprotein cholesterol (VLDL-C), triglycerides (TG)] and atherogenic indices [Castelli’s Risk Indices-I and -II (CRI-I and -II), non-HDL-C fraction, atherogenic index of plasma (AIP), atherogenic coefficient (AC)] were estimated. The G-75A and C+83T loci were not associated with decreased HDL-C risk. This was confirmed across different genetic models (dominant, recessive, additive and allelic). Association was also absent with BP and obesity. However, the G-75A locus was associated with LDL-C, whereas the C+83T locus was associated with TG and VLDL-C. Furthermore, these sites had effects on atherogenic indices. The rare A allele at the G-75A locus was associated with adverse CRI-I, CRI-II, non-HDL-C and AC values, while the major C allele at the C+83T locus was associated with adverse AIP values. Thus, the pro-atherogenic G-75A polymorphism and the anti-atherogenic C+83T polymorphism represent important genetic loci that modulate CVD risk factors in subjects from Assam.
