Abstract
Introduction: Hypertension is a common asymptomatic and usually easy to treat disease. Regarding the fact that genetic, social and nutritional factors responsible for inducing hypertension are not the same in different societies, it is necessary to performe a study to introduce a model of hypertention which includes laboratory measures as risk factors of hypertension at Arak city in 2004. Materials and Methods: This is a case-control study. Study samples were 1000 persons (263 patients with hypertension and 737 healthy people). Samples were selected using multi-stage method in which the population ratio in city and village in both groups was considered. Laboratory findings and ECG results were documented. Data was analyzed using descriptive statistics and logestic regression. Results: In this study hepertensive patients were compared to healthy people. Some risk factors in this study were LVH (p<0.0001), high triglyceride, hypercholesterolemia and hyperglycemia. Also a model was made based on ECG results and laboratory findings to predict the probability of hypertension. Conclusion: By educating physicians about the determined risk factors in this study, they can control them better and decrease hypertension complications in heart, brain, kidney and eye. On the other hand the obtained model can be used in determination of the propable hypertension in people with positive family history

Abstract
Introduction: Nowadays, depression is one of the most prevalent psychological disorders and is a prevalent mood disorder. Recently researches about depression etiology, show that in addition to different neurotransmitters and life events, internal stressors such as serum cholesterol, triglyceride and some coagulation factors can have an effect. This study was focused on the relationship between major depressive disorder and serum cholesterol level. Materials and Methods: This research is a case control study that was performed in the year 2006. Case group were 62 patients referred to Hashemi Senejani psychiatric medical center and control group were chosen from ENT ward patients of Amir-Kabir hospital. Both groups were paired match for age, gender and education. In order to determine serum cholesterol level, 5cc blood sample was taken of each person from both groups. Data was analyzed using K-S and Mann-Witheny U tests. Results: The mean age of samples was 35.5±9.9 years. 77% were female, 67.2% married, 25.8% single and 6.5% divorced. Average serum cholesterol level in case group (215.6 ± 47.6 mg/dl) in comparison to control group (183.1 ± 31.2 mg/dl) was significantly higher (p<0.05). Conclusion: Regarding the results, it seems that serum cholesterol is an internal stressor for depressive disorder so everyone with high serum cholesterol level must be evaluated for depressive disorder.

Abstract
Background: Hyperlipidemia is an important risk factor for cardiovascular diseases. In this study, the effects of physalis alkekengi extract on the levels of cholesterol, low density lipoproteins (LDL), high density lipoproteins (HDL), and triglycerides (TG) were evaluated.
Materials and Methods: In this experimental study, fifty adult male Wistar strain rats were selected and divided into five groups of ten: Control group with a normal diet, control group with a high fat diet receiving interpritoneal injection of saline for 21 days, and treatment groups with fatty diets which received maximum (0.1 g/kg), moderate (0.2 g/kg), and minimum (0.4 g/kg) dose interpritoneal injections of the extract. After this period, blood sampling was done and the obtained results were analyzed through SPSS software.
Results: According to the obtained results, LDL and cholesterol concentrations decreased significantly (P<0.05), whereas HDL and TG plasma concentrations did not reveal any significant changes.
Conclusion: The findings of this study show that such changes are mainly due to the lycopene existing in the plant. Lycopene is a strong antioxidant which inhibits the production of LDL and presumably increases the excretories through releasing cholesterol therefore, it reduces blood cholesterol level and controls cholesterol synthesis.

Abstract
Background:Noticing the side effects associated with chemical drugs, using natural medicinal plants has gained more prominence recently. Physalis alkekengi extract is a medicinal plant belonging to Solanaceae family which similar to most drugs used in traditional medicine, despite possessing a multitude of medicinal properties, has not received sufficient attention. The aim of the present study was to briefly review the effects of Physalis alkekengi extract on the concentration of thyroid hormones, blood cholesterol, some plasma biochemical factors, liver function, immune system, and sexual hormones. Due to the extensive usage of Physalis alkekengi extract in traditional medicine, determining its advantages and possible side effects is of great physiologic and pharmacologic significance. Physalis alkekengi extract due to the presence of such effective substances as alkaloids, lycopene, glucocorticoids, alcoholic agents, and a large amount of vitamin C as well as antioxidant properties can play a significant role in changes in body homeostasis. This study dealt with the function and effect of Physalis alkekengi extract on different body organs through using proper keywords and extensive online search through electronic databases and credible sources. The results of this mini-review showed that Physalis alkekengi extract can bring about various significant changes in different body organs that have not been properly recognized. Therefore, further and more extensive studies should be done on this plant.

Abstract
Background: Probiotics are live microorganisms that have positive effects on the host when consumed in sufficient amounts. According to several studies, probiotics have beneficial effects on prevention and treatment of many diseases. The aim of this study was to review animal and human studies on the role of probiotics in reducing serum cholesterol, their mechanisms of action, and a brief explanation of functional probiotic foods. Materials and Methods: This review article focused on all papers indexed in scientific databases from 2000 to 2012 using the related keywords, including cardiovascular diseases, probiotics, and serum cholesterol. Results: Probiotics are used both in dairy and non-dairy products. Nowadays, the role of many probiotic strains in health is confirmed. From the studies done in this field, it can be inferred that probiotics through several mechanisms, such as binding cholesterol to cell walls of probiotics in intestine, conversion of cholesterol into coprostanol, production of short chain fatty acids, and deconjugation of bile acids, reduce serum cholesterol. Conclusion: Certain strains of probiotics have demonstrated cholesterol-lowering properties and others are under study. Further studies are needed to identify other mechanisms involved in lowering serum cholesterol and determine their safety

Abstract
Background: The main purpose of this study was to measure the level of lipids in ICU patients and its clinical outcome, specially the mortality rate and the relationship between level of lipids and APACHE IV score.
Materials and Methods: This descriptive and cross-sectional study was conducted on 100 ICU patients. Cholesterol level was measured on the first and second days after admission of patients. This was followed by examination of clinical outcome (e.g. mortality rate) and duration of their real and predicted stay through APACHI IV. The results were analyzed by Pearson correlation using SPSS.
Results: Mean serum of HDL, LDL, and cholesterol was lower than normal. These values for the first day were 33.16, 67.97, and 131.38 and for the second day were 23.63, 54.99, and 119.88, respectively. Mean APACH E IV score was 67.72. Result of Pearson correlation coefficient showed significant relationship (p<0.05) between APACHI IV score and cholesterol level of the first and second day, LDL level of the first and second day, HDL level of the second day. Moreover, there were significant relationships were observed between the real mortality rate and the cholesterol level of the first and second days, LDL level of the first and second days, and HDL level of the first day. There was a significant significant correlation between cholesterol level and LDL of the first and second days as well as HDL of the first day and duration of admission in ICU as predicted by APACHI IV.
Conclusion: The significant relationship between lipoprotein level of serum and APACHI IV indicates considering serum lipid beside other physiologic parameters for prediction of clinical consequences including mortality rate of ICU patients
