Abstract
Background: Type 2 diabetes is a hereditary disease but the inheritance and responsible genes have not been clearly clarified yet.
According to the most studies, diabetes is one of the most common causes of mortality and morbidity in populations. Diabetes occurs in 30% of first degree family members of diabetic patients, But most people are not aware of their disease.
Methods: We studied first degree relatives of type 2 diabetes and screened them for diabetes, IFG and IGT.174 families(1556 people) of Tabriz residents were studied, among them 1232 persons grater than 30 years were alive and FBS and OGTT were done in this group .
Results: According to this study, 1232 persons were alive and 324 persons had died and DM was found in 343 (27.9%) and 82 (25.3%) of them respectively. We found 179 (14.5%) persons with IFG and 89 (7.2%) with IGT.The percent of diabetes in offspring and siblings were 32.9% and 22.1% respectively. The majority of patients had 41 – 50 years old. Risk of diabetes among offspring who had diabetes in both parents was more than the ones who had diabetic father or mother. In this study, women with diabetes were more than men (32.4% vs. 22.2% respectively). The prevalence of Diabetes type 2 in first-degree relatives was more frequent between sister and brother (41.95%), followed by that between father and son (10.9%).
Conclusion: Prevalence of diabetes in most populations is 8 – 10 %. If diabetes occurs in someone, risk of development of diabetes will increase to 30% in their family members. Therefore, screening must be done in all family members of diabetic patients to recognize the problem and to prevent from diabetes complication.

Abstract
Background: The goal of dietary recommendations in children with type 1 diabetes mellitus is to achieve moderate to good control of blood glucose regarding to decrease in diabetic long-term complications. Although educational programs on appropriate dietary habits are offered in Isfahan Endocrine and Metabolism Research Center for diabetic patients, there is no information about their dietary habits . This study has been performed to investigate dietary intake in children with diabetes mellitus type1 and to compare the results with that of non-diabetic ones.
Methods: A cross-sectional study was performed in two groups of healthy and diabetic children. Data were collected by questionnaire and interview. The validity and reliability of the questionnaire were determined by content validity and pilot study. Data were described and analyzed by t-student and Pearson correlation tests in four age groups, using SPSS software.
Results: Findings showed that in “A” age group the intake of total calorie and fiber, in “B” age group the intake of fiber, fat, protein, carbohydrate, sugar and SFA, also fat, protein, carbohydrate, sugar and SFA-derived calorie consumption, in “C” age group the intake of sugar and fiber, also PUFA and sugar-derived calorie consumption and in “D” age group the intake of fiber, total calorie, protein, carbohydrate and sugar were higher in diabetic children as compared with the control group.
Conclusion: In all subjects, the intake of carbohydrate and total fat was the same as standard recommendations, while protein intake was a little higher which increases the risk of diabetic nephropathy. In all study groups, fiber intake has been decreased with increasing the age, so it is suggested to have dietary educational programs for general population with the goal of changing the life style of people, which itself can result in less social isolation in school-aged diabetic children.

Abstract
Background: Family satisfaction in subpopulations referred to the endocrine clinic including diabetic and non diabetic patients and their spouses are compared in the present study. This study also assesses the correlation between family satisfaction and variables such as age, sex, educational level, economic status, type of diabetes, duration of the disease, type of therapy and dosage of drugs. A comparison of the frequency of sexual dysfunction between diabetics and non-diabetic pairs was also done.
Methods: In this case- control study, 400 subjects were selected as simplified non-randomized method from outpatients referred to the Shahre Kord endocrine clinic in 2002. We assigned samples to group I (diabetic patients, n=100), group II (diabetic patients spouses, n=100), group III (non-diabetic patients, n=100) and group IV (non-diabetic patients spouses, n=100). Groups I and II were similar in sex, socioeconomic status and educational level. GRIMS family relationship questionnaire was used to evaluate family satisfaction.
Results: Family satisfaction for diabetics in comparison with non-diabetics (P=0.05), diabetics in comparison with their spouses (P=0.003), and non-diabetics in comparison with their spouses (p=0.002) were significantly less. There was no significant difference between family satisfaction in diabetic and non-diabetic patients spouses (p>0.05). Relative frequency of sexual dysfunction was 76% and 29% and relative frequency of decreased libido was 32% an 12%, in diabetic and non- diabetic couples, respectively. Family satisfaction was less in patients with diabetes type I and whom using higher dosage of drugs.
Conclusion: This study emphasized on the attention to the family as a part of approach to the diabetic patients. According to our results, it is recommended to focus the most attention in this field to the patients with type I diabetes and who consume more amounts of drugs.

Abstract
Background: Diabetes mellitus is the most common human metabolic disease. Chronic hyperglycemia and carbohydrate metabolism disorder accompany with plasma lipid and lipoprotein disorder. Cardiovascular disease is one of the macro vascular complications of diabetes type 2 which leads to high morbidity and mortality. Dyslipidemia is one of the major risk factors of cardiovascular diseases in diabetic patients. High TG and low HDL-C levels are the most prevalent type of dyslipidemia. Low levels of HDL-c considered as a risk factor for cardiovascular diseases.
Methods: In this study 40 type 2 diabetic patients (13 male - 27 female) were included. Lovastatin and Gemfibrozil were recommended separately for 2 months and HDL-C were measured at the baseline and after taking drugs. In all patients BS, TG and TC at the baseline before and after these drugs were normal and so were not any change in their diet. Laboratorial findings gathered and analyzed. The relationship between increase level of HDL and decrease of TC with taking Lovastatin and Gemfibrozil were studied.
Results: The averages of TC and HDL-C before taking drug as linear were 36.5mg/dl and 174.56 mg/dl and after taking Lovastatin as linear were 43.3 mg/dl and 150.44 mg/dl. The average of TC and HDL-C after taking Gemfibrozil were 43.33mg/dl and 146.36mg/dl. 18.54 % increase in HDL-C and 13.82% decrease in TC were seen with Lovastatin and 18.54% increase in HDL-C and 16.05% decrease in TC were found with Gemfibrozil.
Conclusion: In this study no difference was observed between the effect of Lovastatin and Gemfibrozil in increase of HDL-C (P=0.449). Also there was no difference between the effect of Lovastatin and Gemfibrozil in decrease of TC (P=0.992). The increase of HDL-C after taking Lovastatin had relation with sex and HDL-C increased in females (P=0.006) Also the increase of HDL-C after taking Gemfibrozil had relation with sex and females had more affected (P=0.035).

Abstract
Leptin is a 16-kD protein which is secreted from white adipocytes and, its discovery has generated enormous interest in the regulation of energy balance. Leptin has been implicated in the regulation of food intake, energy expenditure, and whole-body energy balance in animals and human. Plasma leptin levels correlate with fat storages and respond to changes in energy balance. It was initially proposed that leptin serves a primary role as an anti-obesity hormone, but this role is commonly thwarted by leptin resistance. The profound effects of leptin on regulating body energy balance, make it as a prime candidate for drug therapies of obesity in humans and animals. Despite the recent achievements in unearthing the role of leptin in the pathophysiology of obesity, many important questions still remained that must be responded. More studies with follow-up designs and genetic evaluations are warranted to understand the comprehensive role of leptin in human. In this letter we have a review of known effects of leptin on human obesity up to now.

Abstract
Background: Cardiovascular diseases are the first cause of death in Iran and hypercholesterolemia is one of the most important risk factors. This problem could be partially managed by dietary modifications such as supplementation of diet with dairy products and probiotic bacteria. The aim of this study was to comprise the effect of consuming a probiotic yoghurt and ordinary yoghurt on serum cholesterol levels in mild to moderate hypercholesterolemia.
Methods: This randomized cross-over trial was conducted on 14 healthy subjects aged 40-65 years with total serum cholesterol 200-300 mg/dl. We asked the subjects to avoid consumption of yoghurt for a two-week pre-study period and add 300 g/day of milk to their diet. Then they were randomly allocated to 2 groups to receive either 300 g of ordinary yoghurt (fermented with S.thermophilus and L.bulgaricus) or probiotic yoghurt (fermented with a starter composed of L.acidophilus and B.lactis plus bacteria in ordinary yoghurt) for 6 weeks as substitution for milk. After a wash-out period of 7 weeks, the cross-over was made (those consuming probiotic yoghurt, changed to ordinary yoghurt and vice versa) and the study lasted for another 6 weeks. Anthropometric measurements, a 3-day dietary recall and blood lipid tests were done at the beginning (after a 2-week elimination period of yoghurt from diet) and at the end of each period.
Results: Comparison of weights, BMIs and dietary confounding factors during the period of consuming ordinary yoghurt and probiotic yoghurt, did not show any significant differences. Consumption of probiotic yoghurt in comparison with ordinary yogurt caused a significant decrease in total serum cholesterol (P=0.049). Comparison of other blood lipid criteria did not show any significant differences between these two periods.
Conclusion: Consumption of the yoghurt containing two probiotic bacteria, L.acidophilus and B.lactis, in comparison with ordinary yoghurt causes reduction in total serum cholesterol in mild to moderate hypercholesterolemia.

Abstract
Background: Foot complications are among the important problems of diabetic patients. Vascular and neurological involvements are two major causes for such complications.
Methods: We studied 142 diabetic outpatients referred to diabetes clinic of Dr.Shariati Hospital from Dec. 2003 to Sep. 2004. We performed different neurological and vascular tests to assess the diabetic foot and data were analyzed by SPSS software.
Results: 54.9% of the cases reached the symptom score of 5 and upper so they had neuropathy regarding the Michigan Neuropathy Disability Score (MNDS). By analyzing the overall symptom and sign scores, 61% had neuropathy. Regarding MNDS, 42.7% of the subjects were neuropathic. Finally 23.9% were unable to sense at least one point from 12 points of monofilament examination. 16.9% of the patients had the complaint of intermittent claudication, in 8.8% at least one of the peripheral pulses was not palpable, whereas 10.6% had some degree of PAD regarding to ABI and toe pressure.
Conclusion: Using a monofilament is the most reliable method for screening of the neuropathy in diabetic patients. On the other hand, relying on symptoms like intermittent claudication and physical examination in order to find peripheral arterial disease in diabetic patients may lead to miss many cases, thus, performing some more precise diagnostic tests, such as ABI and toe pressure are highly recommended and reliable.

Abstract
Background: Professionalism is currently a chief concern across the continuum of medical sciences and there is a great deal of efforts to clarify its theoretical components and to measure them. For participation of Iranian medical scientific society in this universal challenge, there is a need to explain and interpret the state of art of this topic in the world.
Methods: We selected the most related articles among the related resources fount through searches of databases, and then asked the related questions of the literature identified
Results: The main core of the professionalism consists of the attitudes and behaviors through them, the patient's interests take priority to the physician's self-interests. Begun in 1990, the professionalism project has reached to its main theoretical results, that is: Physicians' charter on medical professionalism. Regarding the measurement of the professionalism, a reliable and valid measuring method has not been achieved yet.
Conclusion: Achieving to a perfect definition depends on quantifying of its components in the related questionnaires. Regarding the measurement of the professionalism, some great efforts have been done. We propose performing some researches for clarifying the theoretical components and measuring the professionalism in the cultural and professional environment of Iran.

Abstract
Background: The aim of this study was to compare time action profile of regular human Insulin produced by Exir pharmaceutical Co. and Actrapid® HM produced by Novo Nordisk with euglycemic clamp technique for the first time in Iran.
Methods: Euglycemic glucose clamps were performed with two Insulin brands in a single-center, randomized, double-blind, and crossover study on 6 healthy male volunteers. Glucose disposal kinetics including metabolic clearance rate of glucose (MCRg) and metabolic clearance rate of insulin (MCRi) were determined during a 2-h predetermined intravenous Insulin infusion while blood glucose levels were maintained steady using variable continues intravenous glucose infusions based on method of De Fronzo.
Results: There were no differences in glucose kinetics or time action profile with respect to glucose infusion rates (688.4 vs. 664.6 mg/kg per 120min), MCRg (0.63±0.19 vs. 0.62±0.25 ml/kg), and MCRi(110 % vs110%) between Exir and Novo Nordisk regular human Insulin preparations. Serum insulin levels increased and serum C-peptide levels decreased with both exogenous Insulin infusions which were statistically the same for both preparations.
Conclusion: Time action profile and bioavailability of regular human insulin produced by Exir Pharmaceutical Corporation is comparable with commonly used Novo Nordisk preparation demonstrated by 2 hour euglycemic clamp study.

Abstract
Background: It is well recognized that an increased body weight is often associated with increased blood pressure. Moreover, leptin an adipocyte-derived hormone is strongly suggested to have an important role in pathogenesis of the obesity. We aimed to evaluate the levels of serum leptin in association with obesity and hypertension in a sample of Iranian obese children.
Methods: Children from all the primary schools of a distinct of Tehran were screened for obesity. Children with a waist circumference equal to or above 90th percentile for their age and height were invited for the study. Anthropometric measurements were done and blood samples for fasting serum leptin levels were collected from 563 enrolled obese children. Multivariate linear regression analysis was used to evaluate relationship of various factors with obesity.
Results: Mean Serum leptin levels were 8.65 ±2.18 (ng/ml). Serum Leptin levels were higher in girls than boys (P=0.009). There were significant correlations between body mass index (BMI) and serum Leptin levels, child age, systolic and diastolic blood pressure. Systolic blood pressure and diastolic blood pressure lost their association with serum Leptin level in multivariate linear regression analysis.
Conclusion: BMI is independently associated with Leptin levels among obese children. This may affirm a role for this hormone in the pathogenesis of childhood obesity. It seems unlikely that plasma Leptin be a major mediator of association between obesity and hypertension. However, severe hyperleptinemia may act as a risk factor for increased blood pressure.

Abstract
Background: Type 1 diabetes or insulin dependent diabetes mellitus is an autoimmune disease probably caused by various factors such genetics, environmental stresses, viral infections and diet. The disease is associated with damage to pancreatic insulin-producing β cells. Many researches have been performed to study the therapeutic effects of herbal medications on diabetes mellitus. The protective effects of some plants such as Cuminum cyminum, Trigonella foenum-graecum, Saliva sclarea, Allium ampeloprasum etc in diabetes induced rats were reported. Dill with the scientific name of Anethum graveolens, is a plant from umbellifera. This family which contains flavonoid compounds.
Methods: In this research, effects of hydroalchoholic extract of this plant on blood glucose level, lipids and lipoproteins in Alloxan-induced diabetic rats was investigated. Fifteen adult male rats, weighing 200-250 gr, were used in three five member groups. Rats in the control group, received physiological serum. as intraperitoneal (IP). In diabetic control group (DCG), diabetes was induced using Alloxan monohydrate at a dose of 120 mg/kgbw. In addition to diabetes induction just like DCG, the treated diabetic control group (TDCG) rats were dosed with 300 mg/kgbw hydroalcoholic Anethum graveolens extract. All rats received all materials via intraperitoneal injection (IP). 48 hours after the last IP, blood sample was taken from each animal via cardiac puncture to measure blood factors.
Results: The results indicated significant reduction in glucose, total cholesterol, triglyceride, LDL and VLDL levels in TDCG rats compared to DCG rats. Due to the use of dill extract, HDL level was significantly increased.
Conclusion: Effect of Anethum graveolens is related to antioxidant compounds. This compounds affect glucose absorbtion and beta cells regeneration. The results of this research indicate that using hydroalcoholic extract of Anethum graveolens could effectively decrease blood sugar levels.

Abstract
Background: Diabetes is a common endocrine disease in human kind. In most type II diabetic patients, obesity and overweight status account as the serious health problems worldwide and variety of endocrine factors well known that have regulatory role in weight balance and body composition including Leptin and IGF-I factor. The aim of this study was to examine the correlation between Leptin and IGF-I in type II diabetics and controls.
Methods: As a case- control study, 38 type 2 diabetics (20 males and 18 female with mean age 49.22) and 46 healthy controls (16 males and 30 females with mean age 49.52) are recruited. We measured the concentrations of FPG, IGF-I, HbA1C and IGFBP-3 in both groups. FPG was measured by enzymatic glucose oxidase method and Hb Gold analyzer HPLC was used to measure HbA1C. Determination of Leptin, IGF-I, IGFBP-3 and Insulin concentrations were carried out using ELIZA method. P< 0.05 was considered as statistically significant.
Results: The mean of BMI and age were not significantly different in both groups. The mean serum levels of IGF-I, Leptin, Insulin, FPG and HbA1c concentrations in type II diabetics were significantly higher than controls (P< 0.05). In males, the mean serum levels of Leptin were statistically lower than in females in both groups. There was a strong correlation between IGF-I and IGFBP-3, Leptin and insulin, IGF-I and age, and BMI with FPG in both patients and controls (P< 0.05). A reverse correlation was observed between IGF-I and HbA1c in patients and controls (P< 0.05).
Conclusion: It is speculated that based on this findings, Leptin and IGF-I system could have regulatory roles in body composition and fat content particularly in obese and overweight diabetic patients and have significant correlation with Insulin, glucose, BMI and age.

Abstract
Background: Insulin dependent diabetes is an autoimmune disease characterized as a T cell-mediated destruction of insulin-producing β cells. Dendritic cells (DCs) can either induce stimulating or regulatory functions of T cells depending on cytokines microenvironments.
Methods: In this study DCs were generated from mouse bone marrow progenitors through culturing in the presence of granulocyte-macrophage colony stimulating factor (GM-CSF) and interleukin-4 (IL-4) for 7 days followed by two other day treatments with IL-10 or LPS. The DCs were then pulsed with insulin peptide B9-23 and their maturation markers and their ability to induce T cell responses and cytokine profiles were studied.
Results: IL-10 treated DCs had an immature phenotype compared to LPS-treated DCs and expression of MHC-II in LPS-matured DCs was significantly higher than whom were treated with IL-10 (93% and 72% respectively, P<0.04). Although IL-10 like LPS-treated DCs were able to stimulate T cell proliferation, but the IFN-γ production was lower in IL-10 treated DCs (P<0.02).
Conclusion: Using IL-10 treated DCs seems to be useful in prevention and treatment of autoimmune diabetes. However to clarify this hypothesis it needs to study these effects in animal models of insulin dependent diabetes.

Abstract
Background: Experimental studies have shown that walnut (Juglans regia) intake decreases the risk of coronary heart disease (CHD). Walnut decreases the levels of atherogenic lipids such as TG, LDL-C and VLDL-C. Mainly the effect is induced via 3- Poly Unsaturated Fatty Acids (3-PUFA). Walnuts are a rich source of these fatty acids, especially -Linolenic acid (C18:3 9, 12, 15).
Methods: We assigned 20 hypercholesterolemic male Rats (200-250g) to four groups, and fed with four diet concentration of oil extract Persian walnuts(J. regia)(Lavasanate) (w/w ) as complementary diet: control group (0% oil extract) and cases 5%(1g oil extract/1g weight/1 day) ,7.5%(1.5g oil extract/1g weight/1 day),10%(1g oil extract/1g weight/1 day) for eight weeks.
Results: Results revealed there is a positive effect on the decreasing of TG(14%) ,TC(7.8%) , LDL-C(11%),VLDL-C(12%) serum concentrations, with increasing consumption of oil extract Persian walnuts (5% ,7.5% and 10%).
Conclusion: In view of the positive effect of oil extract Persian walnuts (J. regia) consumption on decrease serum concentration of TG, TC, LDL-C and VLDL-C known as atherogenic lipids and lipoproteins, it may be suggested as a CHD protective dietary supplement.

Abstract
Background: Many researches have been conducted on islet cells' transplantation for a definitive treatment of diabetes mellitus type1. As the viability of the islets is the most important factor in predicting the transplantation prognosis, we have designed a study to isolate rat's islets. The aim of the study was to assess the viability of the islets at different stages and suggest the best transplantation time.
Methods: Pancreatic islets were isolated from male rats (250-300gr) by standard surgical procurement followed by intraductal HBSS distension, chopping and digestion with collagenase (type V). After being centrifuged for 3 times, the islets were then hand-picked and incubated in 37oC with RPMI 1640 media for 6 days. Each well contained 35-45 islets. Viability of islets was assessed by 2 independent investigators, giving score 0-2 to the color of islets under florescent microscope after Propidium iodide/Acridine orange staining at 6 times: just after the incubation, 24h, 48h, 3rd day, 5th and 6th day.
Results: The viability of the islet cells was gradually increased after the incubation as we had the most viability rate after the second day, while it decreased after this period and reached the least rate on the 5th and 6th day.
Conclusion: The islets' viability increased following the cell culture after the isolation procedure, as they have the best condition for transplantation after 48 hours. As the islets’ viability is the most critical point in transplantation, further studies evaluating the effects of different interventions on viability is needed.

Abstract
Background: A high dietary lipid intake is an important mediator of cholesterolemia and cardiovascular disease. Oils such as Sesame oil are not thought to contribute to such complications although information on the subject seems to be spare and contradictory. Since the ground seed of Sesame or “Ardeh” is commonly used in certain parts of this country (Iran), so its effects on the serum lipid profile of the rats have been investigated.
Methods: The study was performed on six groups of male Wistar albino rats (10 in each group) weighing 300-350 gr. Ardeh was prepared by grinding the seeds after they had been roasted at 60ºC. To prepare a high cholesterol diet, 1% cholesterol and 0.5% cholic acid was added. Group 1 consumed the ordinary diet 2 the ordinary diet plus Ardeh (24%), 3 the ordinary diet plus sunflower oil (10%), group 4 the high cholesterol diet, 5 the high cholesterol diet plus Ardeh, and group 6 the high cholestrol diet plus sunflower oil, all for 30 days. Blood samples were obtained and sera were used to determine the lipid profile
Results: The results of the study revealed that addition of Ardeh to the ordinary diet decreased serum cholesterol level significantly (P<0.01) in group 2 (38.2±2.3 mg/dl) as compared to the group 1 (49.9±5.9). Ardeh and sunflower oil had a similar effect on the groups, which consumed the high cholesterol diet. Ardeh also reduced the triglyceride level significantly (P<0.01) in group 2 (65.1±7.6 mg/dl) as compared to group 1 (106.3±15.1). Presence of both Ardeh and sunflower in the diets failed to affect HDL, but VLDL levels in group 2 (13.0±1.5 mg/dl) were significantly (P<0.01) lowered as compared to group 1 (21.2±3).
Conclusion: From the results of this study it appears that Ardeh can have a beneficial effect on lipid profiles and its addition to the diet is recommended.

Abstract
Background: Cardiovascular Diseases are becoming increasingly prevalent due to urbanization and industrialization of our country. Therefore Screening of the Cardiovascular Risk Factors is one of the most important health system priorities. The aim of this study was to evaluate a screening method implementing family history for cardiovascular risk factors.
Methods: We chose 10 Junior-high schools in the 6th district of Tehran using simple random sampling. Then a questionnaire asking about family history of cardiovascular disease in the first degree relatives (including grand parents) was distributed between them and was completed –
with contribution of parents. Then high-risk and low-risk families were invited separately to Dr Shariati Hospital for further evaluation. SPSS software version 10 using student T-test, Chi-Square and descriptive tests were applied for data analysis
Results: Approximately 40% of families had positive family history (high risk). From this group, 72% participated for follow-up. From the low-risk group, only 34% participated. Total cholesterol and LDL-C levels were significantly higher in high risk (HR) group. FBS was also significantly higher in fathers and children of the HR group (P<0.05). High TC, LDL-C and FBS levels were more prevalent among the HR families (P<0.05). No significant differences were observed in age, BMI, BP, TG and HDL-C between the 2 groups.
Conclusion: Families with a history of cardiovascular disease participated in greater numbers in the screening process and the prevalence of risk factors in this group was significantly higher. The findings confirm the usability of family history in screening programs.

Abstract
Background: The prevalence of Diabetes mellitus as the most common metabolic disorder of human is progressively increasing. Dyslipidemia is common among diabetic patients characterized by elevated plasma TG, LDL-C and reduced HDL-C levels which increase risk of cardiovascular events. Fish oil supplement which contains omega-3 has been proposed to correct the atherogenic lipid profile associated with diabetes mellitus. Doubt remain whether the net effect of fish oil supplement on lipid profiles are beneficial in diabetes. We therefore performed this randomized double-blind clinical trial to investigate this.
Methods: Ninety six patients with type 2 diabetes mellitus were randomized assigned to take 3 times daily supplementation (capsule) with either fish oil or corn oil for 8 weeks (48 patients in each group). At begining also end of study we measured laboratory variables (FBS, TG, Total cholesterol, LDL and HDL) in both groups.
Results: At begining of the study demographic and laboratory measurements were similar in both groups (P>0.05).At 8th weeks there were no statistically significant differences in variables measured except for LDL and HDL in fish oil group that leads to increase and decrease respectively. Although both groups show improvement in LDL / HDL and Total cholesterol / HDL ratios but mean charges were statistically significant in fish oil as compared with corn oil group. (P=0.001, P=0.005 respectively).
Conclusion: Fish oil supplement showed statistically significant improvement in LDL/HDL, Total cholesterol/HDL ratios as compared with corn oil. This may leads to decrease cardiovascular events.
