Background: Fasting has been recently discovered to improve overall health, but its beneficial effects in the presence of hepatic insufficiency have not been proven. Aim: The influence of fasting on the metabolism, immunological aspects, and oxidative stress of 40 male carbon tetrachloride (CCl4)-intoxicated Wistar rats was investigated in the present study. Methods: The rats were divided into four groups, including a placebo group, CCl4-intoxicated rats, which were injected subcutaneously with 1.0 ml/kg of CCl4 solution, a fasting group, which was fasted 12 h/day for 30 days, and a fourth group, which was injected with CCl4 and fasted. Results: The metabolism, immunity, and oxidative stress improved in CCl4-intoxicated rats fasted for 12 h/day for 30 days, as evidenced in significant increase ( p < 0.05) in total protein, globulin, immunoglobulin M (IgM) and IgG levels, and total antioxidant capacity. In contrast, significant decrease ( p < 0.05) in blood glucose, total cholesterol, low-density lipoprotein-cholesterol, alanine aminotransferase, C-reactive protein, and malondialdehyde levels were observed. Compared with CCl4-intoxicated rats, significant differences in the albumin, triacylglycerol, high-density lipoprotein-cholesterol, very low-density lipoprotein-cholesterol, cardiovascular risk factor, calcium and magnesium levels were not detected. Conclusions: The results of the present study showed that fasting improved metabolism, immunity, and oxidative stress in CCl4-intoxicated rats. Thus, fasting during Ramadan is safe for patients with hepatic disorders, as the prophet Mohammed (S) said “Keep the fast, keep your health”.

AbstractEvidence from observational studies indicates that seaweed consumption may reduce the risk of non-communicable diseases such as cardiovascular disease, type two diabetes, and obesity. Accumulating evidence from in vitro and animal studies suggest seaweed have antihyperlipidemic, anti-inflammatory and antioxidant properties which may in part be attributed to the high content of soluble dietary fibre in seaweeds. The viscosity of seaweed fibres is suggested to mediate antihyperlipdiemic effects via the alteration of lipid/bile acid absorption kinetics to decrease low-density lipoprotein cholesterol (LDL). Thus, there is a need to evaluate the efficacy of seaweed derived dietary fibre in the management of dyslipidemia. Therefore, the aim of this study was to determine the effect of a fibre rich extract from Palmaria palmata on the lipid profile as well as markers of inflammation and oxidative stress in healthy adults. A total of 60 healthy participants (30 male and 30 female) aged 20 to 58 years, were assigned to consume the Palmaria palmata fibre extract (5g/day), Synergy-1 and the placebo (maltodextrin) for a duration of 4 weeks with a minimum 4 week washout between each treatment in a double blind, randomised crossover study conducted over 5 months. Fasting concentrations of cholesterol, triglycerides and high-density lipoprotein cholesterol (HDL) were analysed and low-density lipoprotein cholesterol (LDL) and LDL: HDL ratio was calculated. C-reactive protein (CRP) and Ferric Reducing Ability of Plasma (FRAP) were analysed as markers of inflammation and oxidative stress, respectively. Supplementation for 4 weeks with Palmaria palmata resulted in favourable changes to lipid profiles with a reduced LDL:HDL ratio; however intention-to-treat univariate ANCOVA identified no significant difference between the treatment groups over time on any of the lipid profile markers. A non-significant increase in CRP and triglyceride concentration along with lower FRAP was also observed with Palmaria palmata supplementation. Evidence from this study suggests that Palmaria palmata may have effects on lipid metabolism and appears to mobilise triglycerides. More research is needed in individuals with dyslipidaemia to fully elucidate these effects.

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 aim of this study was to investigate the effects of taurine (TA) on serum lipid profiles following chronic coadministration of chlorpyrifos (CP) and lead acetate (Pb) in male Wistar rats. Fifty rats randomly distributed into five groups served as subjects. Distilled water (DW) was given to DW group, while soya oil (SO; 1 mL kg−1) was given to SO group. The TA group was treated with TA (50 mg kg−1). The CP + Pb group was administered sequentially with CP (4.25 mg kg−1; 1/20th median lethal dose (LD50)) and Pb at 233.25 mg kg−1 (1/20th LD50), while the TA + CP + Pb group received TA (50 mg kg−1), CP (4.25 mg kg−1), and Pb (233.25 mg kg−1) sequentially. The treatments were administered once daily by oral gavage for 16 weeks. The rats were euthanised, and the blood samples were collected at the termination of the study. Sera obtained from the blood samples were analyzed for total cholesterol, high-density lipoprotein cholesterol, triglycerides, and malondialdehyde, and also the activities of serum antioxidant enzymes including superoxide dismutase, catalase and glutathione peroxidase were analyzed. The low-density lipoprotein cholesterol, very-low-density lipoprotein cholesterol, and atherogenic index were calculated. The results showed that CP and Pb induced alterations in the serum lipid profiles and evoked oxidative stress. TA alleviated the disruptions in the serum lipid profiles of the rats partially by mitigating oxidative stress. It was concluded that TA may be used for prophylaxis against serum lipid disorders in animals that were constantly co-exposed to CP and Pb in the environment.

Oxidative stress has been implicated in various pathologies, including hypertension, atherosclerosis, diabetes, and chronic renal disease. The current work was designed with the aim of investigating the potentials of antioxidants copper, manganese, and zinc in the treatment of hypertension in Wistar rats. The rats were fed 8% NaCl diet for 5 weeks and treatment with supplements in the presence of the challenging agent for additional 4 weeks. The supplementation significantly decreased the blood pressure as compared with hypertensive control. The result also indicated significant decreased in the levels of total cholesterol, triglyceride, low-density lipoprotein cholesterol and very low-density lipoprotein cholesterol, malondialdehyde, insulin and increase in the high-density lipoprotein cholesterol, total antioxidant activities, and nitric oxide of the supplemented groups relative to the hypertensive control. The average percentage protection against atherogenesis indicated 47.13 ± 9.60% for all the supplemented groups. The mean arterial blood pressure showed significant positive correlation with glucose, total cholesterol, triglyceride, low-density lipoprotein cholesterol, very low-density lipoprotein cholesterol, atherogenic index, insulin resistance and malondialdehyde while high density lipoprotein-cholesterol and total antioxidant activities showed negative correlation. The result therefore indicated strong relationship between oxidative stress and hypertension and underscores the role of antioxidant minerals in reducing oxidative stress, dyslipidemia, and insulin resistance associated with hypertension.

Beneficial Effects

Low-density lipoprotein cholesterol (LDL-C) is a major cardiovascular risk factor, but other lipid variables such as triglycerides (TRGs), high-density lipoprotein cholesterol (HDL-C) and lipoprotein a [Lp(a)] also affect cardiovascular risk. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors significantly lower LDL-C concentration but also modestly improve the concentrations of TRGs and HDL-C and more robustly decrease Lp(a) levels. The review presents the associated mechanisms of the beneficial effects of PCSK9 inhibitors on the other than LDL-C lipid variables, including the effects on lipid/apolipoprotein secretion and clearance and the heteroexchange between lipoproteins, as well as the possible effects on other variables involved in lipid metabolism such as sortilin. Proprotein convertase subtilisin/kexin type 9 inhibitors improve the overall lipid profile, and these beneficial effects may play a role in the reduction of cardiovascular risk.

Abstract Background: Chronic inflammation may play role in the development of atherosclerosis and its complications. In hypercholesterolemia, the evidences of chronic inflammation such as the stimulation of chemokines and cytokines, increase in endothelial adhesion molecules, and the immune reactions against oxidants on lipoproteins are detected. It was shown that statins had some beneficial effects on lipids, thrombosis, endothelial dysfunction, and smooth muscle proliferation. Aim: To investigate the effects of atorvastatin on hematological and inflammatory parameters in prospective study. Material and methods: Forty patients (14 male and 26 female) with primary hypercholesterolemia were treated with 20 mg/day atorvastatin for 12 weeks, according to Adult Treatment Panel for Third Report of National Cholesterol Education Program. All patients received a detailed description of this study and signed consent prior to enrollment. National and local ethical committees approved this study. The exclusion criteria were secondary hypercholesterolemia, acute coronary syndromes, liver and renal dysfunctions, diabetes mellitus, acute/chronic infection and inflammatory diseases, pregnancy, lactation, malignancy, and tendency to bleeding. At baseline, and 12th weeks, lipid levels such as low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), very-low-density lipoprotein cholesterol (VLDL-C), triglycerides (TGs), and hematological parameters such as whole blood cell counts, hemoglobin and fibrinogen levels, CD3, CD4, CD5, CD8, CD14, CD16, CD19, CD40, CD45 using flow-cytometry, inflammatory parameters such as interleukin-1 (IL-1), IL-6, IL-18, tumor necrosis factor-alpha (TNF-a), interferon-gamma, soluble CD-40, intracellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1, high-sensitive CRP, sedimentation rate, and enzymes including CK, AST, ALT were evaluated. The results were compared with two-paired student’s-t test. Results: At the end of study, atorvastatin decreased TC (p&lt;0.001), LDL-C (p&lt;0.001), TGs (p=0.006), VLDL-C (p=0.012), and HDL-C (p&lt;0.001). While absolute lymphocyte (p=0.003) and platelet counts (p=0.001) were decreased with atorvastatin treatment, absolute monocyte count increased (p=0.002). On flow-cytometric examination, the expressions of CD14 (p=0.015) and CD19 (p=0.039) on lymphocytes were decreased with atorvastatin. Moreover, atorvastatin decreased the levels of TNF-a (p&lt;0.001), sCD40 (p&lt;0.001), ICAM-1 (p&lt;0.001), and IL-18 (p=0.024). ALT increased at the end of treatment (p=0.041). But important adverse events were not seen in the patients. Conclusion: The anti-platelet and anti-inflammatory effects of atorvastatin, independent from lipid-lowering effects, may play an important role on the prevention of atherosclerosis, in addition to its beneficial effects on lipid parameters.

Biomarkers Of Oxidative Stress

Reports from previous studies now provide evidence that dyslipidaemia and oxidative stress play crucial roles in the pathogenesis and progression of diabetes and its related complications. This research is aimed to investigate the potential effects of protein isolate from Parkia biglobosa seeds (PBPI) in streptozotocin (STZ)-induced diabetic rats by measuring blood glucose levels, changes in lipid metabolism and biomarkers of oxidative stress. Diabetic rats were treated orally with graded doses of PBPI, 200 mg/kg bw and 400 mg/kg bw, and 5 U/kg, intraperitoneal (i.p.) of insulin once daily for 28 days with the fasting blood glucose (FBG) monitored weekly. The effect of PBPI on the serum lipid profile was measured while the extent of lipid peroxidation (LPO), as well as antioxidant parameters (superoxide dismutase; SOD, catalase; CAT, glutathione-S-transferase; GST and total glutathione; total GSH), was determined in the cardiac homogenates of diabetic rats. At the tested doses, treatment with PBPI was significantly effective in lowering FBG, serum triglyceride, cholesterol, low-density lipoprotein cholesterol (LDL-c) and very low-density lipoprotein cholesterol (VLDL-c), while concurrently increasing high-density lipoprotein cholesterol (HDL-c). PBPI also significantly decreased the elevations witnessed in LPO levels and restored the biomarkers of oxidative stress in the cardiac homogenate of experimental rats. The results from this study demonstrate that PBPI could improve dyslipidaemia and cardiac oxidative stress in the experimental diabetic animal model possibly by reducing and effectively scavenging reactive oxygen species (ROS) production as well as by increasing antioxidant capacity in combating oxidative stress. Therefore, it can be concluded that PBPI could be explored in the development of a potent cardioprotective supplement or adjuvant therapy towards the management of diabetes and its related complications.
