Abstract

Background and Objective: Polycystic ovarian syndrome (PCOS) is one of the most prevalent (6-10%) endocrine glands disorders among child - bearing women. In addition to the patients, their first degree relatives are exposed to some risk factors such as abnormal lipoproteins. Due to high prevalence PCOS among women and the role of genetic factors in this abnormality, it is necessary to recognize high risk people particularly among first degree relative. Therefore this study was conducted to determine the level of serum lipoproteins in first degree relatives of patients with PCOS. Materials and Methods: This case control study was done on 107 individuals of the first degree relatives of PCOS patients as cases and 107 normal individuals of the first degree of non-PCOS as controls in Shiraz, Iran during 2009. Participants completed a test assessing demographics and blood sample were taken from all participants in order to assay serum lipoproteins including total cholesterol, LDL, HDL and triglyceride. Data was analyzed by means of independent t-test and Fisher's exact test as well as Chi-Square. Results: The means±SD of total cholesterol, HDLc and triglyceride in cases was 191±31.64, 167±4.06 and 191±31.64 mg/dl, respectively. The means±SD of total cholesterol, LDLc and triglyceride in controls was 158.25±18.25, 123±21.33 and 120.42±17.11 mg/dl, respectively. Serum level differences of LDL and triglyceride in cases and controls were significant (P<0.05). The means±SD of HDLc in cases and controls was 40.06±6.95 and 45.9±6.7 mg/dl, respectively (P<0.05). Conclusion: This study showed that the serum level of lipoproteins in the first degree relatives of PCOS patients is significant higher than non-PCOS.

Abstract

Background and Objective: Zinc is an essential ion for living and inter the body from different sources. Since Zn++ interfere on many cellular process such as biological function such as calcium chanalls, this study was designed to investigate the effect of oral ZnCl2 on glucose, Insulin, lipoproteins and liver enzymes in male Rats.

Materials and Methods: This experimental study was performed on 48 of Wistar-Albino male Rats randomly allocated into three exprimental and one control groups. Exprimental groups received 50 mg/l, 100 mg/l and 200 mg/l ZnCl2 in drinking water daily for four weeks but the control group received tap water. After four weeks, animals were anesthetized, sacrificed and blood samples were collected. Glucose, insulin, lipoproteins, aspartat amino transferase (AST) and alanine amino transferase (ALT) were measured. Data were analyzed by SPSS-11, ANOVA and Tukey-tests.

Results: The mean±SD of Cholesterol in group D (85.7±3.2), HDL in groups B, C, D (66.1±2.7, 67±2.18, 68.83±2.69 mg/dl) and LDL in groups B, C, D (2.8±0.9, 14.6±6.3, 13.4±2.8 mg/dl) respectively were significantly decreased compared with Cholesterol (125.5±4.9 mg/dl), HDL (80.5±3 mg/dl) and LDL (30.3±3.2 mg/dl) in group A. Mean±SD of glucose, insulin, triglyceride and liver enzymes did not show any differences among the groups.

Conclusion: This study showed that ZnCl2 added on drinking water reduce serum lipoproteins in male Rats.

Abstract

Background and Objective: Lipoprotein (a) [Lp(a)] is a new cardiovascular risk factor and its concentration increase cardiovascular diseases, while physical activity decrease cardiovascular diseases. This study intend to investigate the effect of eight week walking program on lipoprotein (a) concentration in non-athlete iranian menopausal  women.

Materials and Methods: Twenty two healthy menopause women of 47-55 year of age any specific disorder were enrolled in this study. The subjects randomly divided into experimental and control groups. Anthropometric characteristics including height ,weight, body mass index (BMI), body fat percent and Waist-to-Hip ratio (WHR) and serum lipoprotein on fasting were measured pre and post-walking program. The data were compared using independent t-test, U mann witny and pearson correlation caefficeint was used for assessement of relation between lipoprotein (a) with anthropometric indexes.

Results: According to these results, there was a significant reduction of serum lipoprotein (a) (pre test12.5±4/1 post test 10.5±3md), WHR, BMI and body fat percent prior and after the training in experimental group (P<0.05) while non significant changes was observed in control group. Also, there was non significant relationship between lipoprotein (a) with Anthropometric indexes.

Conclusion: This study revealed that 8-week walking program had useful effects on menopausal women’ serum lipoprotein (a) concentration, WHR, BMI and body fat percent.

Abstract

Background and Objective: Cardiovascular diseases are the most significant factors leading to death. This study was done to determine the effect of eight weeks aerobic training on level serum lipid and lipoprotein in non athletic women.

Materials and Methods: This quasi-experimental study was carried out on 30 non athletic women. Subjects were devided into control and experimental groups through gained Vo2max. HDL-c, total cholesterol (TC), LDL-c, VLDL-c, RF (TC/HCL) and subdermal fat percent were evaluted perior and after training for eight weeks as follow: three session in each weeks with one hour aerobic training in each session. Data analyzed using SPSS-14 and independent and dependent T student tests.

Results: The significant reduction of RF, TC and percent of subdermal fat were observed in experimental group after training in comparison with prieor phase (P<0.05). Significant reduction of RF, LDL-C, TC and subdermal fat were observed in experimental group in comparison with contols after training (P<0.05). The increase of HDL-c and reduction of TG and VLDL-c were observed in experimental group compared to control but these differences were not significant.

Conclusion: This study showed that aerobic training reduce total cholesterol, LDL-c, RF and percent of subdermal fat in non athletic women.

Abstract

Background and Objective: There is a genetic background for polycystic ovary syndrome (PCOS). Due to increase metabolic disorders, lipoproteins, impaired glucose tolerance, and hypertension in PCOS patients, this study was done to determine the cardiovascular risk factors in first relative member of patients with polycystic ovarian syndrom in Shiraz, Iran. Materials and Methods: This case - control study was carried out on 107 parents and siblings of women with PCOS as cases and 107 non-PCOS parents and siblings of women as controls in Shiraz, Iran during 2007-08. Demographic characteristic, BMI, obesity and blood pressure were recorded for all subjects. Serum lipoproteins including total cholestrol, triglyceride, LDL, HDL and fasting blood sugar were measured in cases and controls. Data were analyzed using SPSS-16.5, independent t-test, Chi-Square and Kappa tests. Results: 35.3%, 26.5%, 11.76% and 5.8% of fatheres in cases were considered as overweight class I, class II, class III of obesity, respectively when compared to controls. This differecne was significant (P<0.05). Waist –hip ratio in mothers in cases (25.6%) and controls (17.9%) were higher than 0.85. Waist –hip ratio among the sisters in case and control groups were 23.5% and 17.6%, respectively (P<0.05). Hypertension was observed in 12.2% of cases and 3.7% of controls. This difference was not significant. High level of triglyceride were determined in 14.94% of cases and 6.5% of controls. A significant correlation was found between BMI and diabete II in case and control groups (P<0.05). Disorder in glucose tolerance test (GTT) in case and control goups were 19.62% and 7.47%, respectively (P<0.05). The obesity was found in 18.7%, 6.54% in cases and controls with disorder in GTT (P<0.05). Conclusion: This study showed that obesity, central obesity, high level of serum lipoproteins and hypertension among first relative member of patients with PCOS are significantly higher than the controls.

Abstract

Background and Objective: Obesity and saturated fat diet have a negative effect on plasma lipoproteins. The best therapeutic regiment for the treatment of obesity and reduction of serum lipoproteins is a diet containing non-saturated fatty acids accompanied with aerobic exercise. This study was carried to evaluate the effect of 8 weeks aerobic training and peanut consumption on serum Lipoproteins levels in overweight and obese men. Materials and Methods: This semi-experimental study was done on 36 obese males with age of 41.82±3.4yr, BMI: 32.38±2.50 kg/m2 in North of Iran during 2009. Subjects were divided in three equal groups: aerobic interval training, peanut consumption aerobic, interval training and control. peanut consumption Training group were consumed 50gr peanuts daily. Prior and after training period, serum lipoproteins levels of subjects were evaluated. Data were analyzed using SPSS-16, ANOVA and LSD tests. Results: There was a significant differences between the reduction of total mean serum cholesterol, triglyceride, low density lipoproteins, high density lipoproteins in experiment group II (aerobic interval training and peanut) compare to other groups (P<0.05). Conclusion: Aerobic interval training plus peanut regiment reduce lipoprotein and specifically triglyceride and low-density lipoproteins in overweight and obese men.

Abstract

Background and Objective: Paraoxonase-1 is an important factor in preventing lipid oxidation and formation of oxidized low-density lipoprotein. There are conflicting reports on the impact of physical activity on serum level of Paraoxonase-1. This study was done to determine the effect of four weeks of endurance training on serum level of Paraoxonase-1 and lipid profile in non-athlete obese men. Method: In this clinical trial study, sixteen obese healthy non-athletic men randomly divided into intervention and control groups. Subjects in interventional group were practiced endurance running periodic for four weeks, three sessions a week with 65-80% of maximum heart rate. Blood samples collected 48 hours perior the first and 48 hours following the final training. Serum level of Paraoxonase-1 and lipid profile including cholesterol, triglycerides, low-density lipoprotein and high-density lipoprotein were measured by ELISA method. Results: At the end of the training, the serum level of of paraoxonase -1 increased 15.57% (P<0.05) in interventional group and non-significantly reduced in control group (19.25%). The serum level of serum Paraoxonase-1 in interventional group significantly increased compared to controls (P<0.05). The serum level of low-density lipoprotein in interventional group significantly reduced in comparision with controls (P<0.05). Conclusion: 4 weeks of endurance training increased serum level of paraoxonase -1 and decreased low-density lipoprotein in non-athlete obese men.
