Coronary heart disease is a leading cause of mortality in many countries. Acute coronary syndrome is the basis pathophysiology of coronary heart disease. Complication of coronary atherosclerosis composes rupture of plaque and erosion of vulnerable plaque. Endothelial dysfunction is main influence of coronary plaque erosion. But then recently research oxidative stress and reaction of immunocomplex is leading cause of coronary plaque rupture. So the research background will study markers of endothelial dysfunction, oxidative stress, immune reaction in the complication of coronaryatherosclerosis. Aim: Determine the effect of some marker for causing complication of the coronary atherosclerosis. The research has been conducted using case-control study method. In the case group, patients with complication of the coronary atherosclerosis as determined by coronary angiography (stenosis >85%) as in the control group healthy people with carotid artery stenosis (<0.7mm) has been involved. In the study we defined Anti-oxLDL (anti-oxidized low density lipoprotein) using ELISA Kit (Eucardio Lab, USA) and oxLDL (oxidized low density lipoprotein) titer by ELISA Kit (Mercadio, USA), ADMA (Asymmetric dimethylarginine) titer by ELISA kit (Eucardio Lab, USA) reagents in the enzyme binding reaction. Total antioxidant capacity (TAC) was determined by using spectrophotometer method. The average age of people involved in the research is 57.2±9.72 and for the average age is case group 28 (32%) and 50 (68%) for the control group. ADMA titer level for complication of coronary atherosclerosis or case group is (30.1±1.98 ng/ml) which is (13.2±0.57 ng/ml) greater than the control group. It was statistically significant result (p<0.001). Also titer level for case group is oxLDL (72±2.75 mU/l), anti-oxLDL antibody (766±29.8 mU/ml), which is oxLDL (45.1±2.28 mU/l), anti-oxLDL antibody(603±17.74 mU/ml) greater than the control group. It was statistically significant result (p<0.001). But TAC titer level for control group is (116±2.47 nmol/l) which is (108.3±5.43 nmol/l) greater than the case group. It was not statistically significant result (p=0.098). According to the Binary Logistic Regression test the anti-oxLDL (OR=0.992, p<0.001), ADMA (OR=0.681, p<0.001), TAC (OR=1.017, p=0.105), oxLDL (OR=0.900, p<0.001) levels significantly influence the complication of coronary atherosclerosis. Therefore according to the Binary Logistic Regression test the anti-oxLDL level high significantly influence the complication of coronary atherosclerosis. Anti-oxLDL antibody titer are correlated directly with oxLDL (r=0.413, p<0.01), ADMA (r=0.42, p<0.001) levels. However, correlated negative directly with TAC (r=-0.233, p<0.01) level. Markers of endothelial dysfunction (ADMA OR=0.681, p<0.001) and oxidative stress (oxLDL, OR=0.900, p<0.001), (anti-oxLDL antibody, OR=0.992, p<0.001) high influence causing of complication of coronary atherosclerosis.

BackgroundOut of total 209550 cases of cardiovascular diseases in 2011, 66,7% were newly registered cases.Cardiovascular diseases are the number one cause of mortality in Mongolia; an estimated 6291 peopledied from CVDs in 2011, representing 36.7% of all deaths. It shows that CVD mortality level is higherthan in other countries.Materials and MethodsOur survey is a cross sectional study. We have investigated 600 people of the age of 20-40 whowere randomly selected from 6 urban districts of Ulaanbaatar city. With a permission #4 issued bythe Medical Ethics Control Committee of the Ministry of Health on 25th March 2011, our survey wascarried out between the 1st of July 2011 and the 1st of January 2012 based on the Functional DiagnosticLaboratory, Department of Physiology and Pathophysiology, School of Biomedicine, Health SciencesUniversity of Mongolia.ResultsThe CAVI was significantly higher (p<0.001) in 30-40 aged adults (6.68, 95% CI 6.58-6.78) than 20-29 aged adults (6.42, 95% CI 6.32-6.52). Also CAVI has a direct correlation with the cholesterol level(p<0.05, R2=0,011). Serum cholesterol, triglycerides and LDL levels were significantly higher (p<0.05)in men than women. Framingham Heart Score was in the normal range in 99.2% of the participantswith 4 cases having the score of 10% or higher representing a risk score.ConclusionsDislipidemia, overweight and obesity in young adults are the main causes of vascular dysfunctionsleading to cardiovascular diseases. Thus, the findings of the study demonstrate that helping youths todevelop healthy lifestyles including healthy eating and physical activities shall play a critical role for theprevention and intervention programs designed for development of healthy behavior and lifestyle fromchildhood, especially for the male population, are vital for fulfillment of this role.

Structure, size of trachea and bronchial tree are well known in modern time. There are hundreds of research about respiratory anatomy havebeen done in developed countries. Our team interested that when and how airway structure to become investigated. In Shinong king’s period (2838 – 2699 BCE) human anatomical feature was described rough and ready and note down in books and other treatises. In Guang – Tae king’s period ( 2698 BCE), the trachea divided into 7 pieces in the thorax cavity described in medical treatise named “Nei King” .Since 8th century BCE when autopsy introduced in India, the morphology started in science as evidence based science. All the theories at the time based on research findings represent that medical science has been developed as a evidence based science since 16thcentury in Mongolia. The late 18 century, period of renaissance technology and science, structures of the respiratory system start investigated in detail. 1889 V.Ewart , There are many scientists attempt to measure size of airway structures, unfortunately the results were quite different that may due to material, method and anatomical feature differences. Thus, future intensive research is needed in order to prosecute out previous docotr’s and scientists studies.
