Background: In 2017, incidence of STI accounted for 54.6% of all communicable diseases. Syphilis, gonorrhea and trichomoniasis per 10000 populations are higher than the national average and congenital syphilis has been registered regularly over the past 5 years, which is a major problem today. Thus the study aims to research the knowledge, attitude and practice of sexually transmitted diseases in adults of Dornod Aimag. Methods: The population of Dornod aimag was divided into 4 clusters and one cluster from the aimag center and remaining 3 clusters from soums were selected for the study based on the ratio of population aged between 16-49 years. Random sampling was used to select participants from aimag center and 13 soums and total of 342 people selected for the study. Results: Knowledge of sexually transmitted diseases is insufficient. There is no difference in the level of knowledge of sexually transmitted infections between men and women (p = 0.352). There is a difference in the level of knowledge between age groups and the knowledge level increases with age (p = 0.001). For the question about casual sexual behavior, 21.1% of respondents had casual sex intercourse 2-5 times. Gender differences were seen in attitudes toward casual sex, as 27.8% of male and 14.5% of females had casual sex 2-5 times (p=0.000). 18.1% of respondents used condoms during casual sex, while 13.5% occasionally used condoms, and considering the gender of participants, 24.9% of men and 11.6% of women (p = 0.000) used condom during casual sex. Conclusion In Dornod aimag, there is a lack of awareness of STI and risk behaviors. Furthermore, they have no intention to protect their health due to lack of positive attitude and commitment to protect their sexual health.

background: Our country’s aging for men of 30-39, 40-49 ages it was accelerated aging process and very accelerated aging process. Aging for men of 50-59, 60- 69 ages it was normal aging and slowed aging process. Aging for women 30-39, 40-49 ages it was normal end slowed aging process. Aging for women 50-59, 60-69 ages it was slowed and significantly slowed aging process. Otherwise, aging for young groups was accelerated and very accelerated aging process, aging for old groups was normal, slowed and significantly slowed aging process. The aging process of men was more quickly than women in our country [1].Aim of the stady: To define biological aging, aging indexes and adaptation potential in population of 18- 25 years old of Ulaanbaatar city.Materials and methods: In total 537 person of 18- 25 years from Ulaanbaatar city were chosen for the research study which was conducted in 2012.

Quantity of cells per area was in AH - 10, in AMI – 16 and in CRF 11, but in comparatively healthy condition it was 31.

BackgroundIn Mongolia scientists have been doing research about skin disease and process of aging. Howeverthere has not enough study material about skin aging process which is the key indicator of aging andhow that affect to Mongolian people.GoalMain purpose is to study correlations between main index of skin type of the body, cardiovascularsystem, biological age, epidermal growth factor and blood plasma melatonin, within the people of Uvsprovincial center as they are relatively healthy people.Material and MethodsResearch works were done using cross sectional study model in years 2015-2016, within randomlychosen 400 citizens of Ulaangom city, counted to be relatively healthy people. Research model includes41 questionnaires, examination and blood plasma samples.Basic indexes of the body, cardiovascular system and respiratory functions were chosen by biomarkers,biological age is determined by V.P.Voytenko’s 4th version method and adaptive capacity assessment isdetermined by R.M.Baevskii’s multi-repeating regression method.Main skin type parameters such as porosity, wrinkles, pigmentation, elastics and aging is determined bythe “BOOMTECH skin diagnosis” digital equipment made in the Republic of Korea.The blood plasma MLT and EGF were measured by the method of ELISA analysis ELISA made in thelaboratory of the “AVITSENNA Science and Technology center”.The study material analysis carried out an analysis using logistic regression analysis and Pearson’scorrelation coefficient with SPSS 23.0 software.ResultThere’s an inverse weak correlation between blood plasma MLT and EGF with body wealth characteristicsof Uvs province citizens. It shows that when the blood plasma MLT and EGF decreases the body weight,body height and body weight index increase tendency.In women the decrease of blood plasma MLT and EGF also decreases the body height and body weightindex.Research on correlation between cardiovascular system and blood plasma MLT and EGF shows thatdecrease of blood plasma MLT causes in increased arterial pressures in both sexual groups, decreasedEGF in women causes decreased arterial pressure.Correlation study between skin main characteristics and blood plasma MLT and EGF shows thatdecreased blood plasma EGF in men resulted in decreased skin wrinkles, porosity, elasticity and skin aging index, in women decreased skin pigmentation and elasticity, and increased skin wrinkles, porosity and aging index in women.Research study of correlation between biological age and adaptive capacity assessment with the blood plasma MLT and EGF shows that decreased MLT and EGF in men results in increased biological age characteristics. In other words, the early aging is caused.The logistical regression analyses made using blood plasma melatonin, skin porosity, biological age,body height and sex as the risk parameters of Pearson coefficient and chi-squared parameter. Above model resulted in skin porosity and blood plasma MLT’s are becoming independent variable assessing the skin aging.Conclusions:1. The decreased MLT and EGF’s are resulted in increased body weight, body height and body weight index in men and decreased body height, body weight index in women.2. Decreased blood plasma MLT resulted in increased arterial pressure in both sexual groups and decreased EGF resulted in decreased arterial pressure in women.3. The decreased blood plasma MLT and EGF results in decreased skin wrinkles, porosity, elasticityand skin aging parameter with the increased skin pigmentation in men, as it results in decreasedskin pigmentation, elasticity and skin porosity parameters with the increased skin aging degree in women.4. When epidermal growth factor and blood plasma melatonin is decreased in men it results in increased biological age, but depends directly to the adaptive capacity assessment.5. Skin porosity and blood plasma melatonin were becoming independent variable to assess skin aging.

Background: Cardiac surgery with cardiopulmonary bypass is grown rapidly in last years. The application of cardiopulmonary bypass using a heart-lung machine to perform open heart surgery is known to be associated with numerous pathophysiologic changes including injury of cellular components as erythrocyte, platelets, coagulopathy, and fibrinolysis. Objectives: Our study objective is to study on relation of open heart surgery phases and blood coagulation parameters. Materials and Methods: Blood samples from 49 patients (28 females and 21 males, aged 18- 63 years) who underwent open heart surgery with cardiopulnonary bypass (CPB) were collected before and at several time points during, after surgery and analyzed for coagulation parameters at Shastin Third Central Hospital. Results: To compare long continued cardiopulmonary bypass (over 1 h) surgery with less 1 h groups there prothrombin time was found 18.8±5.9 sec, international normalized ratio (INR) 2.09±0.9 sec prolonged (p<0.001) in 7 days after surgery. All coagulation parameters were decreased significantly (p<0.001) in during extracorporeal circulation and after 1 h declamping than preoperative level and reached near normal value in 48 h after surgery. Our results have referred to platelet counts reduction to about 53% in during surgery, 46.8% in 48 h after surgery of the preoperative level 237.4±57.1 with final return to normal levels 228.9±78.6 within 7 days. Conclusions
1. The cardiopulmonary bypass time and patient age in relation to open heart surgery type there were significant difference (p <0.01).
2. The coagulation parameters have revealed significant changes (p <0.01) in relation cardiopulmonary bypass time.
3. All coagulation parameters were decreased significantly (p<0.001) in during extracorporeal circulation and after 1 h decamping than preoperative level and reached near normal value in 48 h after surgery.
4. There was direct and less correlation between platelet level and CPB time (r=0.37, p<0.001).
