Obesity has been linked with several comorbidities like cardiovascular disorders, diabetes, and hypertension. Weight reduction is directly associated with the consumption of green tea. So, with this premise of background, we evaluated the potential of green tea consumption on obesity and serum lipid profiles in both normo- and hyper-cholesterol emic rabbits. Sixty New Zealand white rabbits (age: 6-8 months; weight 1.5-2 kg) were used for this experiment. Rabbits were randomized and equally divided into three different groups. Group I (control group) received 10 ml/kg of distilled water twice daily, Group II received high cholesterol diet twice daily, and Group III received high cholesterol diet along with green tea solution 10 ml/kg, twice daily for 90 days. Weight measurements and serum analysis were conducted on Day 0 and day 90. For the obtained data, SPSS analysis was performed (SPSS 21). A significant increment of body weight was observed in control (1.97 ± 0.12 vs 2.87 ± 0.21, p<0.0001) and high cholesterol groups (1.91 ± 0.23 vs 3.13 ± 0.31, p<0.0001) at Day 90 when compared with Day 0. Though the results were not significant, there was a reduction in the body weight in the green tea group (2.20 ± 1.47 vs 1.72 ± 0.22) at Day 90 when compared with Day 0. Consumption of green tea for 90 days resulted in weight loss and inhibition of the increase in the levels of TC, LDL, and VLDL. So, green tea can act as a natural food supplement for the management of obesity and dyslipidemia.

Priskila M, Ariningrum D, Suparyanti ES. 2008. Effect of garlic (Allium sativum Linn.) extract on reduction of total cholesterol and HDL cholesterol ratio in hypercholesterolemic rats (Rattus norvegicus). Biofarmasi 6: 45-51. Garlic has been widely recognized as herbal medicine for prevention and treatment of cardiovascular disease, atherosclerosis, and hyperlipidemia. The main bioactive compound, allicin, can influence cholesterol metabolism, reduce total cholesterol and increase HDL cholesterol. The purpose of this research was to find out the effect of garlic extract on the reduction of total cholesterol and HDL cholesterol ratio in hypercholesterolemic rats. This research was an experimental research with pre and post-test control group design. The research used male Wistar rats (Rattus norvegicus) with ±3 mounts old and ±200 grams of body weight. The rats were divided into two groups, group I and II; each group consisted of 15 rats. Before the treatment, all rats were induced by a high-cholesterol diet for two weeks, to get a hypercholesterolemic condition. Group I, as a control group, were induced by a high-cholesterol diet, while group II, treatment group, were also induced by a high-cholesterol diet orally by 0.432 grams garlic extract /200 grams body weight/day. The treatment occurred for 25 days. The data were taken before the treatment and after the last treatment, by taking the blood from orbital sine of rats which been fasted for 12 hours, and the level of serum cholesterol total and the level of serum HDL cholesterol were checked from both groups, then the results were analyzed with t-test. Based on the results, it could be concluded that the oral induction of 0.432 grams garlic extract /200 grams body weight/day for 25 days on rats, could not reduce total cholesterol, therefore the serum total cholesterol and HDL cholesterol ratio was not significant (p>0.05). Meanwhile, the decrease of total cholesterol in treatment group and the decrease of HDL cholesterol in both groups were significant (p<0.05).

Background: Hyperlipidemia or Dyslipidemia is the major cause of atherosclerosis1 and associated conditions. Low levels of high-density-lipoprotein cholesterol (HDL-C) are the major causes of increased atherogenic risk 1. Aggressive cholesterol reduction in patients with atherosclerotic disease is now the standard of care2. In addition to life style modification, patients with risk factors need lipid lowering drug therapy. The drugs available now do not reduce LDL oxidation, and oxidative stress associated with hyperlipidemia. In recent years, antioxidants have been subjected to epidemiological studies4 that have related their consumption to a reduction in the incidence of oxidative damage related diseases.Methods: Hypercholesterolemia was induced in rats by administration of high cholesterol diet for 30 days in standard rat chow diet. Rats were divided into four groups of six each. Group-I and II with intake of normal diet and High cholesterol diet respectively. Group III and IV are given high cholesterol diet along with Lutein 50mg/kg and Atorvastatin 5mg/kg orally once daily respectively. At the end of 30 days animals were subjected to overnight fasting. Blood samples were drawn by retro-orbital puncture for biochemical analysis. The animals were sacrificed after thiopentone injection and liver and aorta were dissected out and processed for histopathological study and biochemical analysis.Results: Lutein treated group showed even more significant reduction in TBARS levels than the normal control group and Atorvastatin treated group. The efficacy of Lutein in slowing down the atherosclerosis and fatty infiltration of liver is proved in this study.Conclusions: Hence the present study had shown significant hypolipidemic, antiatherogenic and antioxidant effect of Luetin in Hyperlipidemic rats.

Seaweed has potential nutrient content such as carotenoids, vitamins, fatty acids, carbohydrates, minerals, and other essential substances. Carotenoids have important biological functions as an antioxidant, and immunostimulatory which can prevent the disease, anti-inflammatory, anti-stress, anti-aging, and protect the skin from the harmful effects of ultraviolet radiation. Seaweed generally consumed as a vegetable by people in Bali, known as the local name Bulung Boni (Caulerpa spp.) and Bulung Sangu (Gracilaria spp.).. So far there has been no report or results of research on the effects of extract ethanol of Bulung Boni (Caulerpa sp.) and Bulung Sangu (Gracilaria sp.) as an antioxidant that can prevent lipid peroxidation which can be seen in decreased level of MDA in liver tissue or blood plasma. Therefore it is necessary to determine of plasmaMDA level of Wistar rat after fed high cholesterol diet treated with extract ethanol of Caulerpa sp. and Gracillaria sp. This experimental study used completely randomized design. Research using total of 24 Wistar rats divided into six sample groups of equal size, all fed with a diet high in cholesterol especially in negative control. The study consisted of negative control group (standard diet), positive control group (high cholesterol diet), high-cholesterol diet with Caulerpa sp. extract dose of 20 mg and 60 mg/100 g, high cholesterol diet with Gracilaria sp. extract dose of 20 mg and 60 mg/100 g body weight rat per day.The study resulted that rats fed high cholesterol diet with treated extract ethanol Caulerpa sp. and Gracilaria sp. with a dose of 20 mg and 60 mg per 100 g body weight rat / day had plasma MDA level significantly lower (p <0.05) compared with rats fed high cholesterol diet without treated with extract of Caulerpa sp. and Gracilaria sp.

This descriptive study investigates in a rabbit model of atherosclerosis (i) the extent of atherogenesis induced by cyclosporine A (CsA) or hyperlipidemia alone or in combination and (ii) whether thymoquinone (TQ), a known herbal antioxidant, offers protection against these effects. New Zealand White female rabbits were assigned to five groups of six animals each: Group I, control; Group II, CsA [25 mg kg−1day−1orally (PO)]; Group III, 1% cholesterol; Group IV, 1% cholesterol + CsA (25 mg kg−1day−1PO); and Group V, 1% cholesterol + CsA (25 mg kg−1day−1PO) + TQ (10 mg kg−1day−1PO). Lipids and oxidative stress parameters [Malondialdehyde (MDA) and protein carbonyl] and aortic atherosclerosis were compared. CsA alone did not show a significant effect on either serum lipids and did not induce atherosclerosis. High-cholesterol diet induced atherosclerosis (45 ± 11% of the intimal surface of aorta was covered with atherosclerotic plaques). CsA and high-cholesterol diet increased atherosclerosis severity as measured from intimal and media lesions, but did not affect the extent of atherosclerosis. TQ decreased aortic MDA by 83%. It was also associated with reduced aortic atherosclerosis extend by 52% compared with Group IV. We concluded that (i) CsA aggravates hyperlipidemia-induced atherosclerosis and (ii) TQ attenuates the oxidative stress and atherogenesis induced by the combined effect of CsA and hyperlipidemia.

Abstract Background Hypercholesterolemia is a major risk factor for cardiovascular disease. It has been reported that pineapple contains healthy nutrients and phytochemicals associated with antioxidant and anti-inflammatory capacities. No investigation exists concerning the effect of pineapple consumption modulating hypercholesterolemia-induced cardiac damage in high-cholesterol diet (HCD)-fed rats. This study evaluated the effect of pineapple consumption on lipid-lowering, cardiac oxidative stress and inflammation in HCD-fed rats. Methods Male Sprague–Dawley rats were fed with HCD, in the presence and absence of Pineapple (Ananas comosus L.) cv. Pattavia powder for 8 weeks. Then, serum lipid profiles, liver and renal function tests, cardiac oxidative stress and pro-inflammatory cytokines were determined. Results Daily pineapple consumption reduced weight gain, serum lipid profiles, atherogenic coefficient (AC), cardiac risk ratio (CRR), and liver enzyme activity, without causing renal dysfunction. Pineapple consumption also restores cardiac protein carbonyl (cPC) content, reduces cardiac malondialdehyde (MDA), cardiac pro-inflammation cytokine IL-6 and IL-1β levels. Conclusion Pineapple possesses antioxidant and lipid-lowering properties and daily consumption alleviates hypercholesterolemia-induced cardiac lipid peroxidation and pro-inflammation elevation in an in vivo model. This study demonstrates that pineapple is a potential candidate for cardioprotection against hypercholesterolemia.

Hypercholesterolemia is one of the important causes of cardiovascular disease related mortality and morbidity and recently it has become a significant issue in public health problem of developing countries. The purpose of the study was to see the effect of glycine max (soy bean) on serum lipid profile of experimentally induced hyperlipidemic rats. Hypercholesterolemia was induced by high cholesterol diet containing 1% cholesterol in olive oil. This study was done on 24 long Norwegian rats (Rattus norvegicus) weighing about 200-210 gram. For convenience, the study was divided into Experiment I and Experiment II. In experiment I, 12 rats were divided into two groups- Group A (n = 6, control group) fed on laboratory diet and Group B (n=6) fed on laboratory diet and soy bean extract for 35 days. In experiment II, the remaining 12 rats were divided into 2 groups, Group C (n=6) were fed on laboratory diet and high cholesterol diet (HCD) for 35 days and Group D (n=6) were fed laboratory diet and high cholesterol diet on initial 10 days and soy bean extract was added along with high cholesterol diet for next 25 days. Serum TC, TG, LDL-C and HDL-C were measured after 35 days. HCD increased TG, TC and LDL-C significantly in group C. Glycine max (soy bean) treated group showed that it decreased plasma TC, TG and LDL-C in experimentally induced hyperlipidemic rats but Glycine max (soy bean) did not show any significant lipid lowering effect in normolipidemic rats. The results of this experimental study indicate that Glycine max can act as a cholesterol lowering agent and thereby can improve cardiovascular functions.Bangladesh J Med Biochem 2017; 10(1): 21-26

Purpose This study aims to evaluate the effect of the combination of tempeh and red ginger flour in hypercholesterolemic rats. Design/methodology/approach Sprague Dawley male rats (n = 30; body weight 150-200 g) were randomly divided by five groups (n = 6), consist of negative control (K−) group: group fed by normal diet (laboratory standard diet laboratory, 4.35 kcal/g, 0% cholesterol); positive control (K+) group: group fed by high cholesterol diet (5.28 kcal/g, 12.1% cholesterol); Treatment 1 (P1) group: group fed by high cholesterol diet and treated by tempeh flour (TF) 1.9 g/200 g body weight; Treatment 2 (P2) group: group fed by high cholesterol diet and treated by red ginger flour (RGF) 0.036 g/200 g body weight; and Treatment 3 (P3) group: group fed by high cholesterol diet and treated by a combination TF 0.95 g/200 g body weight and red ginger 0.018 g/200 g body weight. The lipid profiles and malondialdehyde (MDA) were assessed. Findings The combination of tempeh and red ginger has successfully exerted the total cholesterol (121.9 ± 3.41 mg/dL; p < 0.01), triglycerides (TG) (89.3 ± 2.94 mg/dL; p < 0.01), low-density lipoprotein (39.1 ± 1.59 mg/dL) and MDA (2.0 ± 0.24 mg/dL; p < 0.01) lower than the other treatments. Also, the combination of tempeh and red ginger treatment appeared the highest high-density lipoprotein concentration (63.4 ± 2.26 mg/dL; p < 0.01) compared to the other treatment groups. Total cholesterol and TG were predicted as the increasing of MDA concentration. Originality/value The combination treatments successfully improved the lipid profiles and MDA. Furthermore, the combination of tempeh and red ginger could be effective in supporting therapy as the hypolipidemic condition.
