Abstract
New studies have introduced atherosclerosis as an inflammatory disorder. Usage of anti-inflammatory drugs thus can be useful in preventing atherosclerosis and anti-inflammatory herbal medicines without side effects seem desirable in this view.
Amirkahiria Odorutissima (AO) (umbelliferae) is an Iranian flora being traditionally used a:> an antiinflammatory drug. This study assessed the effects of this plant on the development and progression of fatty streaks.
Methods: Twenty male rabbits were obtained from Iran Pasture institute and were kept under standard condition for two weeks, then randomly divided into four groups with different diets. Groups 1 were fed on rabbit chow (normal cholesterol), group 2 were fed on a high cholesterol diet. group 3 were fed on normal cholesterol diet supplemented with AO, group 4 were fed on high cholesterol diet supplemented with AO. After 12 weeks, the animals were killed and biopsied for their aortas and right and left branches of coronary arteries. Biochemical factors were measured at baseline and after 12 weeks. Levels of cholesterol, LDL, HDL. triglyceride and fasting blood sugar (FBS) were determined by enzymatic methods, and quantitative CRP were determined with turbidometrie methods, malondialdehyde (MDA) and antioxidant capacity were determined with spectrophotometry.
Results: The results indicated that there was a significant difference between AO supplemented group compared with other groups (p<0.05) in terms of mean grade o"' fatty streak o"' right and left coronary arteries and aorta. At the end of the 12 weeks period, cholesterol. LDL and CRP were significantly reduced in the groups 3 and 4 (p<0.05).
Conclusion: This study suggests a protective role for Amirkahiria odoratissima Mozaffahan against the development of fatty streak the mechanism of which should be investigated in future studies.

Abstract
Background: During extrinsic coagulation pathway, a complex is developed between factor VII, calcium and tissue factor (a cell membrane lipoprotein that is exposed after cell injury). Factor VII needs calcium and vitamin K for its biologic activation. Coronary artery disease can be induced by increased level and activity of the coagulation factors VII, VIII and IX. In postmenopausal period, estrogen can decrease blood lipids and thereby decreases risk of coronary artery disease. However, the exact effects of the estrogen on the other predisposing factors of the coronary artery diseases are unknown. Our objective in this study was to evaluate the effects of oral hormone therapy regimen on fibrinogen and other coagulation factors.
Methods: 60 menopause women with history of hysterectomy were randomly allocated in 2 groups. One group was treated with conjugated estrogen 0.625mg/day and the other group was treated with conjugated estrogen 0.625mg/day and medroxy progesterone 2.5mg/day. Serum fibrinogen level and activity of coagulation factors VII, VIII and IX and blood lipids level were checked before and 3 months after treatment.
Results: In the estrogen alone treated group, mean of factor VII activity showed significant elevation 3 months after treatment as compared with prior to hormone therapy(p<0.05). There were no significant changes in means of coagulation factors VIII, IX activities and serum fibrinogen level in estrogen medroxy progesterone treated patients before and after treatment (p>0.05). In both groups, honi1one therapy significantly decreased serum cholesterol level and LDL-C and increased HDL-C (p>0.00) but the serum triglyceride level was increased in the estrogen alone treated group.
Conclusion: Significant elevation of coagulation factors VII with significant elevation of serum triglyceride in estrogen treated patients is explainable. This study confirms that hormone therapy with this protocol does not change serum fibrinogen mean and activity of coagulation factor VIII and IX. This finding may be real or may be related to inadequacy of samples regarding the wide normal range of coagulation factors and serum fibrinogen. Studies with more prolonged follow-up or more samples are suggested.

Abstract
Background: Atherosclrosis is a process that initiated with hypercholestrolemia and fatty streak formation. Previous studies showed oxidative modification of LDL render immunogenic and autoantibodies to epitopes of oxidized LDL. Oxidized LDL (OX-LDL), has antigenic properties. Antibodies against oxidized LDL have been proposed to be independent predictors of atherosclerosis development. The main aims of the current study were to compare antibody titers to different types of oxidized LDL (Cu+2-LDL, Malondialdehyde-LDL) and Native-LDL between angiographically documented coronary patients, non-documented patients and healthy subjects. Correlation between autoantibodies against oxidized LDL and increased risks of cardiovascular diseases has been shown.
Methods: As a case-control study, we evaluated angiographically documented coronary patients, non-documented patients and healthy subjects to measure anti-OX-LDL autoantibody levels.
Enzyme-linked immunosorbent assay was used to measure anti-OX-LDL autoantibodies. ANOVA test used for statistical analysis.
Results: Titers of anti-Malondialdehydo-LDL autoantibodies were 3.55±0.415, 0.361±0.20, 0.093±0.078 respectively in each group (P<0.005). There was not statistically meaningful difference, between native-LDL and Cu+2-LDL antibodies.
Conclusion: It seems the titre of autoantibodies against OX-LDL considered as a predictor of progression of atherosclerosis. Our data provide further support for a role of oxidatively modified LDL in atherogenesis.

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: Atherosclerosis is the leading cause of death necessitates more research to find better solutions to this general concern. Due to the side effects of chemical compounds, more attention has been paid to herbal remedies. This study was designed to investigate the effects of Nigella sativa, on atherosclerosis and its risk factors in hypercholesterolemic rabbits.
Methods: Fifteen rabbits were randomly distributed into three groups of five each.( Normal diet group, hypercholesterolemic diet group (1% cholesterol) and group that received hypercholesterolemic diet supplemented with 5% nigella sativa). Animal groups received their own diets and water for a period of 8 weeks. At the beginning of the treatment period, blood samples were taken from all animals to measure biochemical factors. Same procedure was performed at the end of the period then the left and right coronary arteries and the aorta of each animal were dissected to study fatty streak formation (FSF).
Results: Dietary use of Nigella sativa significantly decreased cardiovascular FSF as well as blood cholesterol and LDL in hypercholesterolemic animals. Though not significant but blood HDL was increased and reduction in C-reactive protein (CRP), triglyceride (TG) and oxidized LDL was observed in the same animals.
Conclusion: The results indicate that Nigella sativa inhibits the development of atherosclerosis. This may be related to the effect of Nigella sativa on plasma lipoproteins in addition to its antioxidant and anti-inflammatory properties.

Abstract
Background: Several studies were pointed to oxidized LDL (OX-LDL) as one of the main immunogenic agents which have important roles in primary lesions of atherosclerosis. In this study, via immunization against OX-LDL with two different antigens in an animal model (rabbit) we tried to clear relation between immune system and atherosclerosis.
Methods: LDL was isolated from healthy human plasma and oxidized with MDA or Cu++. Rabbits were divided to three groups and after 2 weeks (under basic diet) immunized with MDA-LDL or Cu-LDL. In control group Phosphate-buffered saline (PBS) was used. Immunization was repeated with these materials again the weeks of 2, 4, 6, and 8 and concentration of OX-LDL antibody was measured in each stage. At the end of 8th week, rabbits fed normal or high cholesterol regimens. Biochemical factors were measured at the beginning and end of study, also Fatty streaks in aorta and left and right coronary arteries was evaluated.
Results: Immunization with Cu -LDL and MDA-LDL induced adequate antibody formation (IgG) at the end of 8th weeks. Immunization with MDA-LDL significantly decreased the level of cholesterol, LDL-cholesterol and fasting blood sugar (FBS) (P= 0.04). Also a significant decrease in fatty streak lesions was detected in aorta and right and left coronary arteries as compared with non-immunized high-cholesterol group (P= 0.04). Immunization with Cu -LDL significantly decreased Triglyceride, FBS and cholesterol as compared with non-immunized high cholesterol. No differences were detected in the fatty streak lesions in this group as compared with non-immunized high-cholesterol diet cu+2-LDL immunized group, shown significant decrease in CRP as compared with both non-immunized group and high cholesterol diet.
Conclusion: We conclude the protective effects of immune responses on atherosclerosis depend to what kind of antibody, so MDA-LDL and CU-LDL prevent atherosclerosis with different mechanism.

Abstract
Background: Having high knowledge in patients is not sufficient for disease control and it is necessary to get more skills and capabilities that could be helping in confronting with diabetes associated stresses. This study is aim to assess the relationship between coping styles approaches with adherence to treatment in type 2 diabetic patients. Methods: In a cross sectional design 100 type 2 diabetic patients were selected by convenience route. Folkman and Lazaros as well as adherence to treatment questionnaires were filled by participants. Data was analyzed by SPSS software version 16, spearman correlation test and linear regression model were used for inferential statistics. Results: Problem and excitement oriented subscales were significant correlation. The correlation between problem oriented subscale and adherence was positive and significant (P<0.05) so that regression model showed as this subscale increase the adherence was increasing as well. The correlation between excitement oriented subscale and adherence was negative and significant (P<0.05) so that regression model showed as this subscale increase the adherence was decreasing. Conclusion: The results emphasized that there is significant correlation between copying styles and adherence to treatment in type 2 diabetic patients.
