ABSTRACT
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.
