scholarly journals Evaluation of Lipid Lowering Effect of Milk Thistle (Silybum Marianum) in Comparison with Rosuvastatin in Rats by Using Ace-alera® Analyzer

Dyslipidemia is a metabolic disorder that is characterized with an elevation in the cholesterol serum levels that can be treated with various hypolipidemic drugs like rosuvastatin. The present study was undertaken to determine and evaluate the hypolipidemic effect of milk thistle seeds extract in comparison with rosuvastatin and the combination of both for the treatment of dyslipidemia in rats. Also its effect on blood glucose levels on experimentally induced dyslipidemic rats. In vivo studies were conducted on wister albino laboratory rats, in which 49 rats were induced to be dyslipidemic by a daily intragastric administration of cholesterol (2 g/kg). The induction of dyslipidemia was evaluated by comparing these rats with a negative control group that was composed of 10 healthy rats. Then, after one month dyslipidemia was induced in 49 rats that were divided into 6 groups, as the following; positive control group (n=9) received cholesterol (2 g/kg) for another one month, and the other five groups each of 8 rats continued to receive cholesterol (2 g/kg) for one month along with therapy as; rosuvastatin low dose (RL) group received 10 mg/kg, rosuvastatin high dose (RH) group received 20 mg/kg, milk thistle (MT) group received 7.15 mg/kg, (RL+MT) group received a combination of 10 mg/kg of rosuvastatin and 7.15 mg/kg of milk thistle, and (RH+MT) group received a combination of 20 mg/kg of rosuvastatin and 7.15 mg/kg of milk thistle. The statistical results of biochemical analysis showed that all the studied therapeutic protocols whether given alone; RL, RH, and MT or in a combination; RL+MT and RH+MT led to a significant (p≤0.05) hypolipidemic effect that reduced the total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and very low density lipoprotein (VLDL) and increased the high density lipoprotein (HDL) cholesterol levels. In conclusion, all therapeutic protocols were effective in treating dyslipidemia, as they all reduced the TC, TG, LDL, and VLDL, and increased the HDL cholesterol significantly (p≤0.05). Furthermore, we found that milk thistle can be used in the management of dyslipidemia, as it has a hypolipidemic effect. Also, the addition of milk thistle to rosuvastatin therapy reduced the risk of developing diabetes mellitus (DM), as it has a glucose modulating activity either when it was given alone or in combination with rosuvastatin. Moreover, the combination of milk thistle and rosuvastatin was of a great benefit, as it gave an intensive goal of therapy than each one alone in altering all lipid profile parameters.

Aim of the Study: This study was undertaken to ascertain if Hibiscus sabdariffa extract can affect the lipid profile (Total cholesterol (TC), triglycerides (TG), high density lipoprotein (HDL), very low density lipoprotein (VLDL), and low density lipoprotein (LDL)) levels in a paracetamol- induced hepatotoxicity using albino Wistar rat as a model. Materials and Methods: Thirty (30) rats used for this study were divided into three groups. Group A (n=10) served as control. Group B (n=10) was administered paracetamol only at a dose of 750 mg/kg body weight. Group C (n=10) was administered paracetamol (dose 750 mg/kg body weight) and aqueous extract of H. sabdariffa (dose 10 ml/kg body weight) of the animal for 3 weeks. All animals were allowed free access to clean drinking water and normal rat chow. Results: Results of the study revealed that TC was significantly lower (p<0.05) in the paracetamol + H. sabdariffa-treated group as compared to paracetamol-treated group and control respectively. Similar trend was observed with TG, VLDL-c, LDL-c and HDL-c. However, the decrease in HDL-c was not statistically significant when compared to control. Conclusion: The presence of bioactive constituents vis; anthocyanins, flavonoids, polyvenols and free radical scavenging properties in H. sabdariffa enabled a hypolipidemic effect on the animals by lowering the levels of serum TG, VLDL-c, LDL-c despite challenge on the liver. However, it was unable to produce significant effect on HDL concentration -very important cholesterol required in high level to maintain homeostasis inside the body. This may be due to the challenge on the liver as a result of the paracetamol abuse.

Bezafibrate (Bezalip - MCP), an analogue of clofibrate (Atromid-S), has been marketed in the UK for two years. Like clofibrate 1 it lowers both triglyceride and total cholesterol levels in plasma. The reduction is usually in low-density lipoprotein (LDL) cholesterol, whilst high-density lipoprotein (HDL) cholesterol rises. Like other lipid-lowering drugs, it should be used only where appropriate dietary measures have failed and where the hyperlipidaemia poses a significant risk.2

Cholesteryl ester transfer protein (CETP) is a major determinant of plasma levels of high-density lipoprotein-cholesterol (HDL-C) in humans. The anti-atherogenic effect of lowering CETP levels is dependent not only on HDL-C levels but also on a metabolic background of increased low-density lipoprotein or very-low-density lipoprotein. Here we investigated the effects of JTT-705, a chemical inhibitor of CETP, on the development of atherosclerosis in Japanese white rabbits fed on a high cholesterol diet. After 4 weeks on a diet of 0.25% cholesterol-containing chow, 100mg/kg (low dose) or 300mg/kg (high dose) JTT-705 was given, and the animals were monitored at weeks 0, 4, 8 and 12. Aortic atherosclerotic lesions were determined at the end of this period. JTT-705 induced a significant increase in HDL-C in the high-dose group [from 21±3 to 50±7mg/dl (mean±S.E.M.); P<0.0001] compared with the control group (from 21±2 to 27±2mg/dl). The atheromatous area was 60±9% in the high-dose group and 58±9% in the control group. Moreover, correlation analysis showed that triacylglycerol and non-HDL-C levels had a direct relationship with the development of atherosclerosis, but CETP activity and HDL-C levels did not. Thus the CETP inhibitor JTT-705 alone did not have an anti-atherogenic effect in our rabbit model, of severe hypercholesterolaemia suggesting a relatively minor effect of HDL-elevating therapy as compared with decreases in non-HDL-C (or triacylglycerol) levels in patients with severe hypercholesterolaemia, such as familial hypercholesterolaemia.

BACKGROUND: The association between elevated triglycerides and cardiovascular risk has been extensively studied. The elevated level of triglycerides occurs through abnormalities in hepatic very low-density lipoprotein (VLDL) production and intestinal chylomicron synthesis, dysfunctional lipoprotein lipase (LPL)-mediated lipolysis or impaired remnant clearance.CONTENT: Hypertriglyceridemia (HTG) commonly leads to a reduction in high-density lipoprotein (HDL) and increase in atherogenic small dense low-density lipoprotein (LDL) cholesterol, called the atherogenic dyslipidemia (AD). Triglycerides may also stimulate atherogenesis by mechanisms, such excessive release of free fatty acids, and production of pro-inflammatory cytokines, fibrinogen, coagulation factors and impairment of fibrinolysis. Genetic studies strongly support hypertriglyceridemia (HTG) and high concentration of triglyceride-rich lipoprotein (TRL) as causal risk factors for cardiovascular disease. Therefore, lipid management is crucial in reducing cardiovascular risk. Combination of lipid lowering drug therapy may be needed to achieve both LDL and non-HDL cholesterols treatment goal for cardiovascular disease prevention in patients with elevated triglyceride levels, particularly those with triglyceride ≥500 mg/dL.SUMMARY: LDL and non-HDL cholesterol can be a promising target therapy in HTG. Additional clinical outcomes data are needed to provide a more evidence-based rationale for clinical lipid management of hypertriglyceridemic patients.KEYWORDS: hypertriglyceridemia, non-HDL cholesterol, dyslipidemia, CV risk

This study investigated the hypoglycemic, antihyperlipidemic, and renoprotective potentials ofDennettia tripetala(DT) in a rat model of diabetes. The hypoglycemic activity in crude methanol seed extract of DT (CMEDT) and methanol seed fraction of DT (MFDT) measured by glucose oxidase method was increased by 47.37% and 28.72%, respectively, after 8 hours of administration. After 10 days of treatment, CMEDT and MFDT gave a good glycemic control with the highest percentage reduction of 75.82% and 71.34% in glucose level, respectively, which is closely compared with 79.91% in glibenclamide. Using the enzymatic assay and Friedewald’s equation, there was a significant reduction in serum level of total cholesterol (TC), triglyceride (TG), very-low-density lipoprotein (VLDL), and low-density lipoprotein (LDL) and a significant increase in high-density lipoprotein (HDL) (p<0.05) following treatment with CMEDT and MFDT, when compared with the untreated group, although results varied in dosed groups, with high dose of MFDT showing a better lipid-lowering activity. High dose of MFDT improved lipid metabolism and increased percentage protection against atherogenesis by 44%. However, neither CMEDT nor MFDT ameliorated the renal biochemical alteration in urea and creatinine. Thus, the study demonstrates hypoglycemic and antihyperlipidemic potentials of DT seed in diabetes.

This study was carried out to test the hypothesis that Tongxinluo (TXL) as a Chinese herbal medicine enhances stability of vulnerable plaque dose dependently via lipid-lowering and anti-inflammation effects, similar to a high-dose simvastatin therapy. After abdominal aortic balloon injury, 75 rabbits were fed a 1% cholesterol diet for 10 wk and were then divided into five groups for 8-wk treatment: control group, low-dose TXL group, moderate-dose TXL group, high-dose TXL group, and high-dose simvastatin group. At the end of week 16, an adenovirus containing p53 was injected into the abdominal aortic plaques. Two weeks later, plaque rupture was induced by pharmacological triggering. The incidence of plaque rupture in all treatment groups (14.3%, 7.1%, 7.7%, and 7.1%) was significantly lower than that in control group (73.3%; P > 0.01). TXL dose-dependently lowered serum lipid levels and inhibited systemic inflammation. Corrected acoustic intensity and fibrous cap thickness of the aortic plaques were significantly increased, whereas plaque area, plaque burden, vulnerable index, and expression of oxidized low-density lipoprotein (ox-LDL) receptor 1, matrix metalloproteinase 1 (MMP-1), MMP-3, tissue inhibitor of MMP 1, and NF-κB in plaques were markedly reduced in all treatment groups when compared with the control group. Similar to high-dose simvastatin group, high-dose TXL group exhibited a low serum level of low-density lipoprotein cholesterol and ox-LDL, a low expression level of systemic and local inflammatory factors and a low plaque vulnerability index, with no differences in the incidence of plaque rupture among all treatment groups. TXL dose-dependently enhances the stability of vulnerable plaques and prevents plaques from rupture. Simvastatin and TXL offer similar protection in terms of lipid-lowering, anti-inflammation, and antioxidation effects.

This study investigated the effects of berberine on amelioration of hyperglycemia and hyperlipidemia and the mechanism involved in high glucose and high fat diet-induced diabetic hamsters. Golden hamsters fed with high glucose and high fat diet were medicated with metformin, simvastatin, and low or high dose of berberine (50 and 100 mg·kg−1) for 6 weeks. The results showed that the body weights were significantly lower in berberine-treated groups than control group. Histological analyses revealed that the treatment of berberine inhibited hepatic fat accumulation. Berberine significantly reduced plasma total cholesterol, triglyceride, free fatty acid, low density lipoprotein cholesterol, malondialdehyde, thiobarbituric acid-reactive substance, and 8-isoprostane level but significantly increased plasma superoxide dismutase activity. Glucose and insulin levels were significantly reduced in metformin and berberine-treated groups. Glucose tolerance tests documented that berberine-treated mice were more glucose tolerant. Berberine treatment increased expression of skeletal muscle glucose transporter 4 mRNA and significantly decreased liver low density lipoprotein receptor mRNA expression. The study suggested that berberine was effective in lowering blood glucose and lipids levels, reducing the body weight, and alleviating the oxidative stress in diabetic hamsters, which might be beneficial in reducing the cardiovascular risk factors in diabetes.

SummaryPlatelet aggregation, platelet lipid composition and plasma lipoprotein concentrations were measured each week in a group of seventeen alcoholics, without overt liver disease, for one month, following acute, total alcohol withdrawal. The platelets were initially hypoaggregable but, within 1-2 weeks of cessation of drinking, they became hyperaggregable and then gradually returned towards normal values. Hyperaggregability could not be explained by increases in either the cholesterol or the arachidonic acid content of the platelets. Plasma very-low-density lipoprotein cholesterol levels remained high throughout the study, but the initially raised levels of high-density lipoprotein (HDL) cholesterol fell by 26%. Low-density lipoprotein (LDL) cholesterol concentration rose by 10% after two weeks of withdrawal but then returned to about the starting level. The resulting changes in the plasma LDL-cholesterol: HDL-cholesterol ratio, which had increased by more than 50% after two weeks of abstinence, essentially paralleled the time course of enhanced platelet reactivity in all but four of the alcoholics. These findings suggest that alterations in plasma lipoprotein concentrations during acute alcohol withdrawal may be a contributory factor to the haemostatic disorders present in such patients.

Aims: To explore early intensive lipid-lowering therapy in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS). Background: Lowering low-density lipoprotein cholesterol (LDL-C) levels can reduce cardiovascular morbidity and mortality in patients with atherosclerotic cardiovascular disease. Due to many reasons, the need for early intensive lipid-lowering therapy is far from being met in Chinese NSTE-ACS patients at high-risk of recurrent ischaemic events. Objective: To evaluate the feasibility, safety and efficacy of starting evolocumab in hospital to lower LDL-C levels in Chinese patients with NSTE-ACS. Methods: In this prospective cohort study initiated by researchers, 334 consecutive patients with NSTE-ACS who had sub-standard LDL-C levels (LDL-C ≥2.3 mmol/L after regular oral statin treatment for at least 4 weeks; or LDL-C ≥3.2 mmol/L without regular oral statin treatment) were included. Patients who agreed to treatment with evolocumab (140 mg subcutaneously every 2 weeks, initiated in hospital and used for 12 weeks after discharge) were enrolled in the evolocumab group (n=96) and others in the control group (n=238). All enrolled patients received regular statin treatment (atorvastatin 20 mg/day or rosuvastatin 10 mg/day; doses unchanged throughout the study).The primary endpoint was the change in LDL-C levels from baseline to week 12. Results: Most patients (67.1%) had not received regular statin treatment before. In the evolocumab group, LDL-C levels decreased significantly at week 4 and remained stable at week 8 and 12 (all p<0.001). At week 12, the LDL-C percentage change from baseline in the evolocumab group was -79.2±12.7% (from an average of 3.7 to 0.7 mmol/L), while in the control group it was -37.4±15.4% (from an average of 3.3 to 2.0 mmol/L). The mean difference between these 2 groups was -41.8% (95% CI -45.0 to -38.5%; p<0.001). At week 12, the proportions of patients with LDL-C levels <1.8 mmol/L and 1.4 mmol/L in the evolocumab group were significantly higher than in the control group (96.8 vs 36.1%; 90.6 vs 7.1%; both p<0.001). The incidence of adverse events and cardiovascular events was similar in both groups. Conclusions: In this prospective cohort study we evaluated the early initiation of evolocumab in NSTE-ACS patients in China. Evolocumab combined with statins significantly lowered LDL-C levels and increased the probability of achieving recommended LDL-C levels, with satisfactory safety and well tolerance.
