ABSTRACTObjective. The aim of the present work was to evaluate the effects of Lipofundin 20% on lipid peroxidation markers in the liver of New Zealand white rabbits. Materials and methods. The animals were treated with an intravenous injection (2 ml/kg) of the lipid emulsion during 8 days through the marginal ear vein. At the end of the experiment some lipid peroxidation parameters and lipid profile were tested through spectrophotography. Results. Lipofundin was found to induce a significant (p<0.05) increase of malondialdehyde, total hydroperoxides, and peroxidation potential. Also, high levels of total cholesterol, triglycerides, LDL - cholesterol and HDL-cholesterol were observed in treated animals compared with the control group (p<0.05). Conclusions. Data proved that Lipofundin induces hepatic lipid peroxidation in rabbits, mainly through a mechanism which involves an induction of hyperlipidemia

Evaluation of the phenolic compounds and antioxidant activity ofCedrela odorataL. andJuglans regiaL. bark extracts was performedin vitro.Juglans regiashowed greater extract concentration and higher antioxidant activity. Hypoglycemic activity in rats was assessed by generating a glucose tolerance curve and determining the area under the curve (AUC). Diabetes was later induced by an injection with streptozotocin (65 mg/kg of b.w.) and confirmed after 24 hours. The extract was administered (200 mg/kg b.w.) over 10 days, and blood glucose was monitored and compared with a control group. The glucose AUC showed a hypoglycemic effect ofJ. regiaandC. odoratain normal rats. Both extracts reduced hepatic lipid peroxidation in diabetic rats. Polyphenolic extracts reduced cholesterol levels in a hypercholesterolemic mouse model and decreased hepatic lipid peroxidation. Polyphenolic extract doses of 100 and 200 mg/kg b.w. were administered alone or with cyclophosphamide (CPA) 50 mg/kg ip, which was used as a positive control. Analyses were performed using leukocytes in a comet assay after 4 and 24 h of treatment. Genotoxic effects were evaluated by the comet assay, which showed that whileJ. regiaextract had no effect,C. odorataextract induced slight damage at 200 mg/kg, with the formation of type 0 and 1 comets.

Abstract: Squid ink consists of DHI, DHICA, and 2-carboxyl indole that improve lipid profile and remove foam cells in blood vessel walls. This study was aimed to analyze the effect of squid ink on atherosclerosis-induced Wistar rats. This was an experimental study. We used randomized controlled trial with pre-post test design for lipid profile assessment and randomized post-test only control design for blood vessel evaluation (foam cells in layers of coronary artery). Samples were 27 Wistar rats, divided into three groups; all were atherosclerosis-induced with initial injection of 0.006mg iv adrenalin on day 1, followed by standard diet and egg yolk until day 30. Squid ink extract was given to group P1 and P2 on days 15-30 in different doses, but not to control group. Data were analyzed by using Saphiro-Wilk test and paired t-test. The results showed that P2 group had decreased means of total cholesterol (-33.62 mg/dl), triglyceride (-28.00 mg/dl), and LDL cholesterol (-28.16 mg/dl), but an increased mean of HDL cholesterol (11.60 mg/dl). There were decreased numbers of foam cells in the layers of coronary arteries of P1 and P2 group compared to the control group. Conclusion: Squid ink extract could lower total cholesterol, triglyceride, and LDL cholesterol levels, and increase HDL cholesterol level. Moreover, it could remove foam cells from the layers of coronary arteries.Keywords: squid ink, atherosclerosis, lipid profile, foam cells Asbtrak: Tinta cumi memiliki kandungan DHI, DHICA, dan 2-carboxyl indole yang dapat memperbaiki profil lipid dan mengurangi sel busa pembuluh darah.

This study was carried out to evaluate the possible mechanisms through which an aqueous extract from MO leaves demonstrates hepatoprotective effects in alloxan-induced diabetic rats. Eighty albino rats were assigned to 4 groups. The control group was orally administered sterile saline. The second group was injected with alloxan (150 mg/kg body mass (b.m.)) by intraperitoneal injection (i.p.). The third group was given MO (250 mg/kg b.m.) orally, daily. The fourth group was injected with alloxan, as for the second group, and administrated an aqueous extract of MO leaves, as for the third group. Alloxan induced degenerative changes in hepatic and pancreatic tissues, increased hepatic lipid peroxidation, and increased gene expression of PC and caspase 3. However, it decreased the activities of hepatic SOD and CAT, and gene expression of GS. In contrast, the MO extract prevented changes to the histoarchitecture of hepatic and pancreatic tissues and normalized the reduced hepatic levels of glutathione, as well as the activities of SOD and CAT, and the gene expression of GS, while reducing blood glucose levels, hepatic lipid peroxidation, and the gene expression of PC and caspase 3. This study indicated that an aqueous extract of MO leaves can be a potent antioxidant and used as an hepatoprotective agent.

ABSTRACT Introduction Obesity is emerging as an epidemic worldwide. Obesity is associated with a number of comorbid conditions, such as diabetes mellitus, hypertension, cancer, dyslipidemia, cardiovascular abnormalities, anemia, obstructive sleep apnea, and psychosocial abnormalities. Aim This study aims at comparing the lipid profile levels of obese and nonobese men. Materials and methods This was a case—control study conducted at a tertiary care center. Totally, 80 men in the age group of 20 to 47 years attending the master health checkup were included in the study, out of which 40 men with normal body mass index (BMI) of 18 to 25 belonged to group I and 40 men with increased BMI of 30 and above belonged to group II. Lipid profile parameters, such as triglycerides (TGLs), total cholesterol, high-density lipoprotein (HDL) cholesterol, and low-density lipoprotein (LDL) cholesterol were estimated in them. The data were statistically analyzed using Statistical Package for the Social Sciences (SPSS) software version 15.0. Results Statistically significant difference was found in the total cholesterol levels with a p-value of 0.040 while the difference in LDL cholesterol was statistically highly significant with a p-value of 0.040. Conclusion Among lipid profile parameters, only total cholesterol and LDL cholesterol showed significant difference between the obese and nonobese individuals. However, the other parameters like HDL cholesterol and TGLs did not show any significant difference. How to cite this article Babu SV, Jagadeesan AR, Ramalingam J.

Red dragon fruit (Hylocereus polyrhizus) peel contains anthocyanin, fiber and vitamin C, so it can be used to improve lipid profile in dyslipidemia. The peel of the dragon fruit is not durable, so in this study we used freeze-dried dragon fruit peel. The aim of this study was to prove that the administration of the red dragon fruit peel in a dose of 0.72 g/200 g BW, 1.08 g/200 g BW, and 1.44 g/200 g BW of rat per day for 28 days may improve lipid profile in male wistar strain white rats with high-fat diet. Lipid profiles were studied by examining of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides. This was a pure experimental study using randomized post test only control group design. This study used experimental animal of 30 male wistar strain white rats which were divided into five groups. Measurements of total, LDL, and HDL cholesterol levels were done by CHOD-PAP method, while triglyceride level was measured with GPO-PAP method. Data were analyzed statistically by One Way Anova test. The results of this study indicated that giving the peel of red dragon fruit as much as 0.72 g lowered total cholesterol levels, 1.08 g lowered total and LDL cholesterol levels, and 1.44 g lowered total cholesterol, LDL cholesterol, triglyceride levels, and raised HDL cholesterol level. Red dragon fruit peel can be used alternatively to improve lipid profile in dyslipidemia.

Objective: To contribute to the knowledge of some aspects of the Healthy Life Style by studying the effects of including legumes in the diet and exercise at two intensity levels, along with the lipid profile of young sedentary women living at 2640 meters above sea level. Materials and methods: The study included a non-randomized clinical trial with four intervention groups: exercise at 45% VO2 peak plus legumes in diet, exercise at 65% VO2 peak plus legumes in diet, only exercise at 65% VO2 peak, and only inclusion of legumes in diet. In each group, 20 to 23 sedentary women were included. The intervention was carried out for four weeks, three days a week. Exercise prescription was based on measurement of VO2 peak by ergospirometry; and the current intervention was monitored with heart-rate monitors. The outcome variables were total serum cholesterol, LDL cholesterol, HDL cholesterol, and triacylglycerols measured at baseline and after two and four weeks of intervention. Results: The measurements taken of participants in the group of exercise at 65% VO2 peak plus legumes in diet showed a reduction of 19.8 mg/dl in total cholesterol, of 21.8 mg/dl of LDL cholesterol, of 20.7 mg/dl of tracylglycerol, and an increase of 6.2 mg/dl of HDL cholesterol. The serum levels of HDL also increased in the group of only exercise at 65% VO2 peak. No significant changes in serum levels were documented for participants in the group with only dietary modifications. Conclusions: The results suggest that different interventions that meet some of the criteria for healthy eating and life style show different effects with regards to the level of change in the lipid profile components.
