Abstract Context Patients with lipodystrophy have dyslipidemia and insulin resistance. Leptin treatment with metreleptin in lipodystrophy decreases insulin resistance and lowers triglycerides without changing high-density lipoprotein. Detailed measurement of lipoprotein particles with nuclear magnetic resonance (NMR) spectroscopy can offer insights into cardiovascular disease (CVD) risk and lipid metabolism beyond a standard lipid panel. We hypothesized that patients with lipodystrophy would have a more atherogenic lipid profile than controls at baseline, which would be ameliorated with metreleptin treatment. Objective To characterize the lipoprotein profile in patients with lipodystrophy compared with controls and to evaluate effects of metreleptin treatment. Design, Setting, Patients, and Intervention Patients with lipodystrophy (N = 17) were studied before and after metreleptin for 2 weeks and 6 months and compared with 51 insulin-sensitive sex-matched controls. Main Outcome Measures Lipoprotein profiles were measured by NMR with the LP4 deconvolution algorithm, which reports triglyceride-rich lipoprotein particles (TRLPs), high-density lipoprotein particles (HDLPs), and low-density lipoprotein particles (LDLPs). Results Patients with lipodystrophy had elevated large TRLPs and smaller HDLPs and LDLPs compared with controls. Five patients with lipodystrophy had chylomicrons, compared with zero controls. Metreleptin decreased the size and concentration of TRLPs, eliminated chylomicrons in all but one patient, decreased LDLPs, and increased LDLP size. Metreleptin treatment did not have major effects on HDLPs. Conclusions Patients with lipodystrophy had an atherogenic lipoprotein profile at baseline consistent with elevated CVD risk, which improved after metreleptin treatment. The presence of fasting chylomicrons in a subset of patients with lipodystrophy suggests saturation of chylomicron clearance by lipoprotein lipase.

The efficiency of oat bran and barley bran in lowering the induced hyperlipidemia and hypercholesterolemia in blood of male Albino rats (Rattus rattus) was studied. Twenty rats were divided into four groups each consisted of five rats and fed the specified test diets for eight weeks. The first group (G1) is the negative group which was fed basal diet, the second group (G2) was fed 1.0% cholesterol, was the third group (G3) fed 1.0% cholesterol and 10% oats bran, and the fourth group (G4) was fed 1.0% cholesterol and 10% barley bran. Feeding rats on 1% cholesterol significantly increased serum total cholesterol, low density lipoprotein, and very low density lipoprotein and triglyceride and decreased serum high density lipoprotein. Furthermore, enzyme activity of alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase was increased, and lipid peroxide was increased, whereas catalase and glutathione-S-transferase were decreased. Kidney functions parameters in the cholesterol supplemented group were elevated compared with the negative control. In addition, histological alteration in kidney, liver, heart, and testes was observed, compared with the negative control. Hypercholesterolemic rats supplemented with oat bran and barley bran showed significant decrease in lipid parameters, significant increase in high density lipoprotein-cholesterol, improved antioxidant enzyme, and improved histopathology of kidney, liver, heart, and testes. In conclusion, both oat bran and barley bran had protective effects against induced hyperlipidemia and improved histological alterations. Oat bran appeared more efficient than barley bran in lowering the lipid profile levels in hypercholesterolemic rats.

Tea Benalu (Scurrula atropurpurea [Bl.] Dans.) and Mango Benalu (Dendrophthoe pentandra L. miq.) containssecondary metabolites with potential antioxidant potential. Antioxidants can inhibit the oxidation process and reduce Total Cholesterol, Triglycerides, Low-Density Lipoprotein (LDL) and increase High-Density Lipoprotein (HDL). The safety of the preparations for the combination of parasites of tea and mango leaves was tested to obtain toxic effects after repeated treatment tests over some time. The purpose of this study was to determine the toxic effects of a combination of methanolic extracts of a combination of tea parasites and mangoes in female rats (Rattus norvegicus) subchronically for 28 days by looking at the results of the clinical biochemical examination on lipid profiles, namely total cholesterol levels, triglycerides, high-density lipoproteins (28%). HDL), and Low-Density Lipoprotein (LDL). The method of this study was experimental with a combination dose of methanol extract of tea parasite leaves and mango parasite leaves at a dose of 250 mg / KgBB, 500 mg / KgBB and 1000 mg / KgBB with 5x replications each treatment. The subjects used white rats (Rattus norvegicus) female Wistar strains aged 6-8 weeks with a minimum body weight of 100 grams. The treatment in this study was in the form of each dose given 5 times a week for 28 days (subchronic toxicity test) orally. Lipid profile levels were analyzed using the one-way ANOVA test. The results showed that the level of control blood lipid profile with a treatment dose of 250 mg / KgBW, 500 mg / KgBW, and 1000 mg / KgBW was not significantly different. The toxicity test of combined extracts of tea leaves and mango parasite leaves of female rat Rattus novergicus on subchronic exposure 28 days with those doses showed no difference tangible between treatments of controls. This means it is safe and does not cause toxic properties in the lipid profile of female wistar rats.Keywords: Lipid Profile, Scurrula atropurpurea, Dendophthoe pentandra, Sub-Chronic Toxicity, Rattus norvegicus ABSTRAKBenalu Teh (Scurrula atropurpurea [Bl.] Dans.) dan  Benalu Mangga (Dendrophthoe pentandra L. miq.) mengandung metabolit sekunder berpotensi sebagai antioksidan.
