Abstract
Background & Objectives: Regarding the high prevalence of hyperlipidemia in the world especially in Iran, finding suitable and effective treatment seems justified. Metronidazole is the only drug that is used as an antiparasital and antiprotozoal agent. Researchers have found that oral dose of 750 mg/day has a suitable absorption, is widely distributed in the tissues and reaches to a blood level of 4-6 mg/ml. Despite its suitable efficiency, a few clinical trial have been conducted in this regard. This study was designed as such to examine the effect of metronidazole on lowering blood lipids. Methods: The present research was performed as a clinical trial without control, on 50 patients. All the patients filled out a special form (to show their satisfaction) as well as a questionnaire. Metronidazole was given with a daily dose of 750 mg for a week. 20 patients with no complaint continued their drug consumption for another seven days. Lipid parameters such as plasma total lipid, total cholesterol, and triglyceride were measured in both groups. The data were collected and analyzed with SPSS software using t-test. Results: Measuring the serum level of lipids indicated that the mean total plasma lipid and total cholesterol decreased significantly compared to their level before taking the drug (p<0.01). The findings also showed a similar decrease in plasma TG level (p<0.001). In the patients who continued the drug consumption in the second week, the serum level of lipids under study showed more decrease compared to their levels in the first week which was statistically significant (p<0.01). Liver tests indicated that the functioning of liver has not changed during drug consumption. Conclusion: Using 750 mg of metronidazole per day exerts a significant decrease in lipids fractions in a short time. Most cases of hyperlipidemia require a long-term treatment, hence metronidazole can be effectively used in the treatment of short-term hyperlipidemia.

Abstract
Background & Objectives: The ischemic stroke is defined as cerebral dysfunction due to brain infarct which is induced by vascular obstruction. The related risk factors including hypertension, diabetes mellitus, cardioembolism and hyperlipidemia are investigated in several studies. The aim of this study was to determine the etiology of cerebral infarction in young adults ( - year-olds). Methods: All the patients in the age rang of - admitted to the neurology ward of Alavi Hospital in Ardabil between 2004 and 2005 with a diagnosis of cerebral infarction were included in this study. A questionnaire including demographic data, personal and family history of stroke and cardiac infarct, hypertension, diabetes, smoking and hyperlipidemia was filled out for all patients. Blood sugar, cholesterol, anticardiolipin antibody and beta- glycoprotein were examined. The patients underwent echocardiography. The data were analyzed using SPSS software (release ). Results: The total number of the patients was , including females (71.1%) and males (28.9%). The mean age was (SD= ). The etiologic factors based on their frequency were: cardioembolism ( ), positive antiphospholipid antibodies (35.5%), hyperlipidemla ( ), smoking ( ), hypertension ( ), oral contraceptive use ( ) and diabetes mellitus (13.7%). Conclusion: The most frequent etiologies of the cerebral infarcts in the young adults in this study were cardiogenic embolism and positive antiphospholipid antibodies. Other background factors were hyperlipidemia, smoking, hypertension, oral contraceptive use and diabetes mellitus respectively. Most of these etiologies can be intervened and prevented. The identification of these factors before occurrence of cerebral infarction can prevent this debilitating event.

Abstract
Background & Objectives:Lipid peroxidation has recently attracted considerable attention. It has been linked to carcinogenesis, aging and variety of other diseases including atherosclerosis. Atherogenesis involves the complicated interaction between cells of the arterial wall and lipoproteins (mainly oxidized LDL). The aim of this study was to investigate the relationship between serum malodialdehyde (MDA), the important indicator of lipid peroxidation and alteration in serum lipids and lipoproteins concentrations in male patients with coronary artery disease (CAD). Methods: The subjects of this study were 51 male patients under 55 with angiographically comfirmed CAD admitted to Shahid Madani Hospital and 60 age and sex matched apparently healthy individuals as the control group. The serum level of MDA was measured by colorimetric method using thiobarbituric acid reaction and lipid and lipoproteins concentrations were determined by standard enzymatic methods. Results: Significant elevation in the level of MDA was noticed compared to the controls (P=0.03) . Serum concentrations of cholesterol, triglyceride, LDL-C and LDL - C /HDL - C ratio in cases were higher than those of the controls (P=0.03) . There was a positive and significant relationship between serum MDA and biochemical risk factors including Triglyceride, Cholesterol, LDL-C and LDL - C/HDL - C ratio (p=0.03). The correlation between serum MDA and serum HDL-C was negative and meaningful (P=0.03) . No relationship was observed between serum MDA with BMI and age in cases. Conclusion: Simultaneous control and monitoring of both dyslipoproteinemia and lipid peroxidation may be of equal importance in prevention of occurrence and progression of CAD.

Abstract
Background & Objectives: Diabetes mellitus may be associated with the imbalance between protective effect of antioxidants and increased free radical production with regard to discrepancies of the findings in previous researches the present study set out to determine the changes of plasma malondialdehyde and erythrocyte antioxidant superoxide dismutase activity in patients with type II diabetes mellitus. Methods: This case-control study was conducted in 2005 using random sampling. 38 patients with type II diabetes mellitus who referred to 5th Azar diabetes center and 19 age and sex matched healthy controls were selected for this study. Heparinated blood samples were taken from the cases. The separated plasma was tested for blood sugar, lipid peroxidation and blood cells (for glycolisated Hb and superoxide dismutase enzyme activity). The collected data were analyzed by SPSS (ver. 10) using t-test. Results: The level of plasma malondialdehyde from type II diabetes mellitus patients (6.27±0.80 nmol/ml) was significantly different from that in control group (3.56±0.98 nmol/ml)(p<0.05). Erythrocyte superoxide dismutase activity from type II diabetes mellitus patients (678.78±59.36 U/gr Hb) was significantly lower than control group (1056.47±52.98 U/gr Hb) (p<0.05). Conclusion: The significant difference between the increase in malondialdehyde and decrease in the activity of antioxidant enzymes in patients with type II diabetes mellitus may predispose to the development of serious complications leading to cellular damage. This suggest that diabetic patients may need more antioxidants than normal. Supplementation with medical or non-medical free radical scavengers such as vitamins E and C or foods untaining vitamin C (sitrus fruits) have a potential role in reinforcing antioxidant defence and can be important in diabetic patients.

Abstract
Background & Objective: Hyperlipidemia is one of the main causes of cardiovascular diseases which have a high mortality throughout the world. Consumption of products containing specific strains of microbes as probiotics, produces positive effects in the host by balancing the flora of the digestive system. L.casei is a probiotic and the aim of this study was to evaluate the effects of consumption of milk containing L.casei on serum lipid profile of rats fed high lipid diet. Methods : This was an experimental study in which 30 male albino wistar rats with a body weight of 200 ± 15 gr were randomly allocated to two groups of treatment and control each containing 15 rats and adapted to a high lipid diet (11.47%) and water containing milk (25%). Rats in both groups received high lipid diet and water containing 25% milk for 48 days with the difference that rats in the treatment group received water containing L.casei considering that water consumption is created throughout the experiment, the amount of L.casei added to milk was calculated to each rat consumed 109 CFU bacteria per day. Results : Independent t-test revealed that at a level of α= 0/05 mean levels of total cholesterol and LDL-C of rats in the treatment group was significantly lower than that of control group (p<0/05), but the mean levels of triglyceride, HDL-C and VLDL-C was not significant. Also increase in body weight was significantly higher in the treatment group compared to the control group (p<0/01). Conclusion : Long term daily consumption of milk containing L.casei improve serum lipid profile by lowering total cholesterol level and also increase the rate of body growth.

Abstract
Background & Objectives: Previous studies demonstrated that selected probiotic bacteria elicit beneficial effects in animals. Probiotic bacteria inhibit pathogens growth in the gut, improve lipid metabolism and activate immune system of animals. In the present study Enterococcus spp were isolated from Iranian traditional cheese and their effects on intestine pathogens ( Shigella dysenteriae, Escherichia coli and Salmonella Typhimurium) growth, serum lipids level and activation of immune systems in mice were studied. Methods: Iranian cheese samples were collected from Ardabil province. Enterococci spp were isolated using selective culture mediums and identified using API kites. Inhibitory effects of isolated Enterococci on growth of Pseudomonas aeruginosa and intestine pathogens (Shigella dysenteriae, Escherichia coli and Salmonella typhimurium) were tested using agar well method . In order to study probiotic activities of isolated bacteria in live animals, NMRI mice were divided into different groups and Enterococci was administrated orally (1 ML/mouse) with doses equal to 2 (6×108 cfu/ml) 3 (9×108 cfu/ml) and 4 (12×108 cfu/ml) MacFarland standard for 2 weeks. After two weeks continues treatment, blood samples were collected from retroorbital sinus and serum levels of cholesterol, triglycerides, LDL and HDL measured using enzymatic method. Interleukins (IL-2, IL-6 and IL-10) levels were measured using ELISA kites. Results: Results of this study demonstrated that treatment with faecium species decreases serum cholesterol and increases serum IL-10 level, while it has not showed significant effects on serum levels of glucose, triglycerides, IL-2 and IL-6 (p<0.05). Administration of faecalis species have no significant effects on lipid levels of serum ( p <0.05). Moreover, results revealed that treatment with faecalis species increased IL-6 and IL-10 ( p <0.05). None of the species affected pathogens growth significantly ( p <0.05). Conclusion: The results obtained from current study demonstrate that continues treatment with both species can affect immune functions of animal by altering the cytokines profile and treatment with faecium species decreases serum level of cholesterol.

Abstract
Background & objectives: Diabetes mellitus is a common metabolic disorder resulting from insulin deficiency or resistance. One of the most common problem in diabetic patients is atherosclerotic cardiovascular disease which induced by hyperlipidemia. Primary strategies for prevention of atherosclerotic cardiovascular disease are lowering of the lipids level by food and drugs. Zinc as an essential trace element may affect plasma lipid status . The aim of this study was to evaluate the effect of zinc on the levels of plasma lipids in patients with type II diabetes. Methods: In this clinical trial study, 60 diabetic patients were divided intwo groups. The first group received 25 mg/kg/day zinc and second group received 50 mg/kg/day zinc for 8 week. The levels of fasting serum lipids, lipoproteins and zinc were evaluated in each group before and after administration of zinc. SPSS software (V.11.5) and t-test were used for statistical analysis. Results: In the study procedure in each group 8 patients were excluded and 22 patients completed the study. There were not significant changes in the levels of zinc and serum lipids between before and after zinc treatment in the first group (25 mg/kg/day). The serum levels of zinc significantly increased after administration of 50 mg/kg/day zinc in the second group (160 ± 30 μg/dL vs 140 ± 30, p = 0.002). There also were significant changes in the levels of LDL-Cholesterol, total cholesterol before and after zinc supplementation in the second group (50 mg/kg/day). LDL significantly reduced after supplementation (123.9±33.53 vs 96.5±32.50, p=0.001), cholesterol reduced (226.68±31.40 vs 199.8 ±37.8 p=0.001), HbA1C reduced after zinc supplementation (9.7±1.86 vs8.9±1.5, p=0.02). Conclusion: It seems that Zinc at higher doses (50 mg/kg/day) is effective to decrease the levels of serum lipids and glycosylated hemoglobin in diabetic patients.

Abstract
Background & Objectives: Elevated apolipoprotein B-100 and decreased Plasma HDL due to hypertriglyceridemia are common abnormalities in insulin-resistant subjects that increase the risk of cardiovascular disease. The aim of this study was to investigate the effects of 8 weeks progressive aerobic exercise (AE) on blood glucose, lipidand lipoprotein profile, and aerobic power in adults with type 2 diabetes. Methods: Twenty nine women with type 2 diabetes (mean age 43.4 ± 1.7 years and blood glucose range of 150 to 230 mg/dl ) were divided into a control (n=14) and exercise (n=15) groups. Exercise group participated in an aerobic training program 3 times per week for 8 weeks. The intensity of aerobic exercise was 60–75% of HR max. The control subjects were asked not to alter their physical activity patterns. All subjects underwent anthropometric, lipid profile and aerobic power evaluation, at the baseline and 48 hours after last session training. Following a 12 h overnight fasting, a venous blood sample was drawn for the analysis of total cholesterol (TC), triglycerides (TG), high density lipoprotein (HDL), low-density lipoprotein (LDL), and (apoB100). Paired t test and analysis of covariance (ANCOVA) were used to analyze the data. Results: Significant improvement was observed in FBS, aerobic power, percent body fat, (Apo) B-100 and triglycerides (p< 0.05) for the exercise compared with the control group after training. No significant difference was observed in TC, LDL and HDL between two groups. Conclusion: According to our findings moderate intensity physical exercise can be effective in preventing the atherosclerosis via significant improvement in blood sugar, cardiovascular endurance, Apo B-100 and triglyceride in patients with type 2 diabetes.

Abstract
Background & Objectives: Diabetes mellitus is a metabolic disease characterized by hyperglycemia together with biochemical alterations of lipid profile, insulin resistance and inflammation . Considering the high prevalence of hypertension, dyslipidemia and inflammation in type 2 diabetic patients, the aim of the present study was to investigate the effects of inulin on lipid profile, inflammation and blood pressure in women with type 2 diabetes. Methods: In this controlled, randomized clinical trial, 49 women with type 2 diabetes (fiber intake<30 g/d, BMI=25-35 kg/m2) were assigned to one of two groups. Experimental group (n=24) received 10 g/d inulin and control group (n=25) received 10 g/d maltodextrin for 8 weeks. Dietary intakes, anthropometric measurements, blood pressure, serum lipids and hs-CRP concentrations were measured at the baseline and at the end of the study. Data were analyzed using SPSS software (verision11.5). Paired, independent t-tests and ANCOVA were used to compare quantitative variables. Results: At the end of study, there was a significant decrease in systolic blood pressure (from 135.7 ± 16.2 to 125.9 ± 7.9 mmHg), total cholesterol ( from 192.5 ± 42.8 to 171.0 ± 39.7 mg/dl), triglyceride ( from 223.3 ± 84.2 to 169.9 ± 65.6 mg/dl) and hs-CRP ( from 7.9 ± 3.0 to 5.3 ± 3.0 mg/l) in inulin group compared with the maltodextrin group (p > 0.04 ). Changes in diastolic blood pressures, LDL-c and HDL-c were not significant in inulin group compared with the maltodextrin group. A significant decrease in systolic, diastolic blood pressures, total cholesterol, triglyceride, LDL-c, hs-CRP and significant increase in HDL-c were observed in inulin group compared to baseline. Conclusions: Inulin supplementation may improve lipid profile, hs-CRP and blood pressure in women with type 2 diabetes.

Abstract
Introduction : Cardiac events due to coronary artery disease (CAD) are the most common cause of death in all over the world. Myocardial ischemia and its consequent heart failure are considered as common problems and complications of CAD. The purpose of this study was to assess the anti-ischemic effects of fibrates in patients with CAD. Methods : This clinical-trial study was conducted on patients with dyslipidemia and CAD referred to the Baqiyatallah university hospital, Tehran, during 2008-2010. A total of 124 patients randomly divided into two groups: the first group (64 patients) received simvastatin (20-60 mg/day)+fenofibrate (200 mg/day) with lipid-limited diet and exercise and the second group (60 patients) received simvastatin (20-60 mg/day) with diet and exercise for one year and the patients were evaluated at the end of this period. Results : The mean age was 54.3±6.5 years and 53.2% of patients were male. Metabolic equation index was changed from 4.32±0.5 to 5.68±0.5 at the first group (P<0.001) and 4.43±0.9 to 4.41±1.1 at the other one (P=0.121) and also time of exercise was changed from 5.21±1.81 to 6.01±1.8 (P<0.001) and 5.43±1.26±5.23±1.2 (P=0.089) respectively. No serious adverse effects were seen. Conclusion : Lipid-lowering therapy with simvastatin and fenofibrate reduces myocardial ischemia. Therefore it’s recommended to add fenofibrate to statinsin the treatment of dyslipidemia in patients with high risk of cardiovascular accidents as complementary treatment.

Abstract
Background: Obese patients are at high risk of numerous chronic diseases including diabetes, hypertension, heart disease, dyslipidemia and stroke. Recently researchers focused on complementary medicine along with routine treatments to reduce obesity complications. Therefore we aimed to investigate the effects of omega 3 fatty acids supplementation on serum lipid profiles, C-peptide and fasting blood glucose in obese individuals. Methods: In this randomized clinical trial 56 obese volunteers with the mean age of 33.94±8.15 years were assigned into the supplemented (n=30) and placebo (n=26) groups, given two omega 3 fatty acids soft gel (360 mg EPA and 240 DHA) or placebo respectively for 4 weeks. At the onset and the end of the intervention, blood samples were collected after overnight fasting and serum lipid profiles, C-peptide and fasting blood glucose were measured. Data were analyzed with SPSS program and p-value less than 0.05 considered as significant. Results: In comparison with placebo group, omega 3 supplementation resulted in a significant decrease in the mean triglyceride (108.37±11.22 mg/dl vs 148.84±59.40 mg/dl). After 4 weeks, the mean C-peptide concentrations increased in both groups but elevation in omega 3 group was more dramatic (p<0.01). However, we didn’t find any significant changes in the mean total cholesterol, LDL-C and HDL-C levels. Conclusion: Our finding indicated that 4 weeks Omega 3 supplementation leads to amelioration in some of serum lipid profiles indices and insulin secretion in obese individuals. Although, further studies are needed to achieve precise results.

Abstract
Background & objectives: In this study, we aimed to determine the extent of possible genetic influence on cardio-metabolic risk factors and to evaluate the familial aggregation of metabolic syndrome (MetS) in a Tehranian population.
Methods: In a cross-sectional observational study, the anthropometry, blood pressure andbiochemical measurements were examined in each member of 566 nuclear families. The role of risk factors in MetS and the Pearson partial correlation between MetS and lipid related factors were calculated.
Results: The prevalence of MetS among the mothers and girls was 78.4 and 12.9%, respectively. Grandmothers had the highest incidence of atherosclerotic risk factors. Four factors were found which explained 77.7% of the overall variance. Recurrence risk ratio among siblings was 5.61 (95% confidence interval [CI]: 3.15-9.97). The adjusted odds ratio (OR) of proband’s MetS status was 1.33 (95% CI: 1.06–1.67) and adjusted OR for the four factors to predict MetS were all significant with the obesity factor having the highest risk (OR: 7.50, CI: 5.91–9.52) followed by dyslipidemia/hyperglycemia factor (OR: 4.86, CI: 4.03–5.87), and blood pressure factor (OR: 4.20, CI: 3.51-5.02).
Conclusion: The present findings confirm the idea of familial aggregation and the recurrence risk ratio in MetS traits. Sibling correlations were higher than other relatives indicating the high genetic factors of these quantitative components in which a high risk of MetS (two-fold) was found

Abstract
Background & objectives: Iron overload is involved in the pathophysiology of many diseases including diabetes. In fact, the excess iron by creating free radicals makes damage to pancreas and leads to insulin resistance and diabetes. Andrographolide extract has hypoglycemic and antioxidant properties. This study has surveyed the effects of andrographolide on blood glucose and lipid profile in rats with secondary iron overload.
Methods: In this experimental study, 36 male Wistar rats were randomly divided into 6 groups: the healthy control group, secondary iron overload group, secondary iron overload groups treated with a dose of 3.5 and 7 mg/kg of andrographolide extract, and andrographolide groups treated with a dose of 3.5 and 7 mg/kg of extract. Iron and extract were injected for 6 and 12 days, respectively. Blood samples were taken for measurement of blood glucose and lipid profiles. Data were analyzed using ANOVA test.
Results: The pathological results of samples from liver of animals receiving iron showed that the iron was deposited in the liver tissues. Iron injection significantly increased blood glucose levels compared to healthy control group (p<0.05). In the iron overload group, andrographolide extract with a dose of 3.5 mg/kg or 7 mg/kg significantly decreased blood glucose levels (p<0.05). Iron injections did not increase the serum triglyceride and cholesterollevels. Injections of andrographolide extract with a dose of 3.5 mg/kg and 7 mg/kg, significantly decreased the cholesterol levels compared to iron receiving group (p<0.05).
Conclusion: Results of this study showed that the andrographolide with different doses may be effective in the treatment of diabetes by reducing serum glucose and cholesterol levels.

Abstract
Background & objective: Aloe-vera is an herb that has long been used in traditional medicine. Using high-fat diet and fatty liver disorder cause obesity and hyperlipidemia. So, this study aimed to investigate the effects of Aloe - vera gel extract on the body weight and lipid profile in adult male rats treated with high-fat diet.
Methods: In this experimental study, 40 adult male rats were included in the control group (no treatment), sham group (treated with high-fat diet 10 ml/kg) and three experimental groups receiving high-fat diet (10ml/kg) along with 150, 300 and 600 mg/kg Aloe- vera gel extracts. Prescriptions were conducted by gavage, for 60 days. At the end, after anesthetizing the rats and phlebotomizing their heart, the serum levels of cholesterol, triglycerides, LDL and HDL were measured. The obtained results were analyzed by ANOVA and Duncan tests.
Results: The results showed that high-fat diet significantly increased the serum levels of cholesterol, triglycerides, LDL (p<0.001) and weight gain (p<0.01) but had no significant effect on the serum level of HDL. However, in the groups receiving Aloe -vera gel and high-fat diet, there was a significant decrease in the weight and serum levels of cholesterol, triglyceride (p<0.05) and LDL (p<0.01).
Conclusion: High-fat diets increase the weight and serums levels of triglycerides, LDL and cholesterol. Also, the Aloe- vera gel extract causes weight loss and improves lipid profiles in the rats treated with Aloe -vera gel extract.

Abstract
Background & objectives: Due to the widespread use of zinc oxide nanoparticles (ZnO-NPs) and their possible unwanted effects in biological environments, we made an attempt to investigate the effect of ZnO-NPs on the blood lipid profile.
Methods: In this study, 24 male Wistar rats were used. The rats were randomly divided into three groups: control group, the group receiving ZnO-NPs at 25 mg/kg (ZnO-NPs 25 mg/kg) and the group receiving ZnO-NPs at 50 mg/kg (ZnO-NPs 50 mg/kg). The duration of the test was two weeks. The blood samples were taken and the serums were separated. Serum levels of triglyceride, cholesterol, VLDL, LDL and HDL were determined using standard kits and methods.
Results: Based on the findings of this study, serum levels of triglyceride and VLDL in both ZnO-NPs receiving groups were significantly increased in comparison with the control group (p<0.05). Also, the serum levels of HDL , LDL and LDL/HDL ratio decreased significantly in both ZnO-NPs receiving groups compared to the control group (p<0.05), while the serum cholesterol levels did not change compared with the control group.
Conclusion: Our results showed that 25 and 50 mg/kg doses of ZnO-NPs had both harmful (increase triglyceride and VLDL and reduction of HDL) and beneficial (reduction of LDL and LDL/HDL ratio) effects on the blood lipid profile.

Abstract
Background & objectives: Curcumin has antioxidant properties. The aim of this study was to determine the effect of curcumin on bax, bcl-2, antioxidant enzymes and lipid peroxidation of sperm after freezing procedure.
Methods: In this experimental study, semen samples were collected from four mature Holstein bulls, twice a week in eight innings. Semen samples were divided into four groups. Zero (control), 10 (Experimental group one), 20 (Experimental group two) and 30 (Experimental group three) mg/ml of curcumin with diluents were added to the semen samples. After thawing, Bax, Bcl-2 and malondialdehyde levels as well as superoxide dismutase, glutathione peroxidase and catalase enzymes were measured in sperm samples using ELISA.
Results: According to the results, Bcl-2, superoxide dismutase, glutathione peroxidase and catalase levels in sperm samples treated with 20 and 30 mg/ml curcumin significantly increased and Bax and malondialdehyde levels significantly decreased compared to control groups (p<0.05). This difference was not significant for sperm samples treated with 10 mg/ml curcumin.
Conclusion: Dose-dependent administration of curcumin decreased oxidative stress and lipid peroxidation and increased anti-apoptosis proteins in freeze-thawing sperms.

Abstract
Background & objectives: Recent evidence suggests that bone morphogenetic proteins (BMPs) are involved in regulating of adipose tissue. This study aimed to evaluate the effect of three resistance training methods on bone morphogenetic protein 2 and lipid profile in obese men.
Methods: In a semi-experimental trial, 44 obese men (23-32 years) were selected and randomly divided into four groups, including control, interval resistance training, traditional resistance training and circuit resistance training. Interval, traditional and circuit resistance training performed with an intensity of 50% of maximum repetition and active rest, 3-time sessions per week for 12 weeks. Serum BMP-2 levels were measured using an ELISA kit. Data were analyzed using paired t-test, one-way analysis of variance and Tukey post hoc test at the p<0.05.
Results: The results showed that interval, traditional and circuit resistance training were associated with a significant decrease in bone morphogenetic protein 2 (BMP-2), LDL, cholesterol and triglyceride concentrations in interval, traditional and circuit resistance training groups, and also a significant increase in HDL concentration in interval and circuit resistance training groups in comparison with the pretest (p<0.001). BMP-2 levels were significantly lower in the interval resistance training group than in the traditional resistance training group (p<0.001). The HDL and LDL, cholesterol and triglycerides levels in obese men in the interval and circuit resistance training groups were significantly higher and lower than in the interval resistance training group, respectively (p<0.001).
Conclusion: 12 weeks of the interval, circuit and traditional resistance training were associated with decreased BMP-2 and improved lipid profile in obese men, and interval resistance training may be more effective on BMP-2 and lipid profile in obese men.

Abstract
Background: Obesity is a major health problem worldwide. Therefore, the purpose of this study was to determine the effects of l-carnitine supplementation on physical factors related to health and lipid profiles in obese female children with basic gymnastics exercises.
Methods: In this quasi-experimental study, with a pre-test-post-test design and a placebo group, 60 obese children among the girl students of Isfahan with BMI=30.28 kg/m2 were selected purposefully and were divided into 4 groups (Basic gymnastics training, L-carnitine consumption, Combined, and Placebo). The training protocol was implemented for 12 weeks, three times a week, and 45 minutes for each session. Furthermore, the groups of L-carnitine consumption and combined used L-carnitine tablets with a dose of 2 g per day for 12 weeks. To analyze the data, multivariate covariance, and post hoc Tukey tests were used.
Results: A significant increase in Cardio-respiratory endurance, muscular endurance, muscular strength and flexibility was observed in both basic gymnastics training and combined groups (p≤0.001). In addition, a significant decrease in total cholesterol, triglyceride, and LDL and a significant increase in HDL were observed in the basic gymnastics training, and combined groups (p≤0.002). Also, the changes caused by the combined group on all variables were significantly better than other groups.
Conclusions: These findings indicate the beneficial effects of basic gymnastics training along with L-carnitine supplementation on physical factors related to health and lipid profile in obese children. Therefore, the combined use of basic gymnastic exercises and L-carnitine supplementation can be useful to improve these variables.
