Background: The physiology and intellectual traits of individuals are interrelated and should be studied comprehensively. In traditional medicine, the teachings of wind (khi), bile (shar), and phlegm (badgan) are considered an integrated system for maintaining health, preventing diseases, diagnosing, and treating illnesses. Aim: Our research is to study students’ physical indicators, body composition, innate characteristics and the relationship between physique and psychological factors. Materials and Methods: The study was conducted on relatively healthy individuals, did clinical observations and used a cross-sectional study design. (defined as those experiencing internal physiological changes that do not impair their work capacity or active lifestyle) Results: Participants were aged 19-25 years, with an average age of 21.5. Heights ranged from 149 cm to 198 cm, with an average of 165.7 cm. Weights ranged from 37 kg to 111 kg, with an average of 61.55 kg. The Body Mass Index (BMI) varied between 15.3 and 36.3, with an average of 22.36. The majority of participants were female (76.4%), while male participants accounted for 23.6%. Regarding individual constitutional types, the most common were: predominantly bile with wind characteristics (21.2%), predominantly bile with phlegm characteristics (30.8%), predominantly wind with bile characteristics (19.6%). Stress survey results ranged from a minimum score of 0 to a maximum of 50, with an average score of 20.6, indicating slightly below-average psychological well-being. The correlation between physiological traits and psychological survey scores was R=0.323** (p=0.001), showing a weak but positive correlation. This suggests that below-average psychological well-being is only minimally influenced by physiological traits. Conclusion The stress survey results indicated an average score of 20.6, slightly below the normal psychological index. The correlation between constitutional traits and psychological well-being was weak but positive (R=0.323**, p=0.001). This implies that individual constitutional characteristics have a minimal effect on psychological well-being. In the study of intrinsic unique characteristics, it has been found that certain physical constitution metrics of the participants demonstrate both positive and negative correlations with the majority of body types, indicating that individuals exhibit varying physical constitution characteristics. Additionally, there exists a positive but weak correlation between intrinsic unique characteristics and stress levels, warranting further investigation.

Background: Establishment of quantitative reference intervals of white blood cells and its subpopulations using a high accuracy analytic system is essential for clinical medicine, public health, and anthropology. We are unable to identify peer-reviewed literature sources describing white blood cell counts and their subpopulations using monoclonal antibodies to specific surface antigens in healthy Mongolians. This study aimed to measure the counts of white blood cells and their subpopulations in healthy Mongolians using flowcytometry. Materials and Methods: The absolute number (cell/L) of leukocytes (CD45+), granulocytes, monocytes and lymphocytes were measured by Magnetic Activated Cell Sorting Assay (MACSQuant Analyzer 10) in 287 blood donors (158 males and 129 females) 17-64 years of age (mean age 33.1±12.4). Peripheral blood samples were collected at the time of blood donation at the National Center for Transfusion Medicine. Results The mean values of leukocytes and granulocytes were lower in donors over 30 years of age (ANOVA: F=4.408, p=0.002 and F=5.685, p=0.001) and regression analysis demonstrated indirect correlation between counts of these cells and age of donors (r= - 0.198, p=0.001 and r=-0.221, p=0.001, respectively). Gender-related differences in white blood cell counts were not found.
Mean value of lymphocyte count in donors investigated in spring (May and March, n = 87; 2224.6±775.3) was significantly higher than those in winter (December – February, n=180; 1613.2±454.3, p=0.001) and autumn (October, n=20; 1576.1±438.6, p= 0.001).
Comparing of our findings with the data from available literature shown that healthy Mongolians have lower leukocyte count compared with Koreans, Chinese Han population and lower mean value of lymphocyte count comparing with Korean, Chinese Han population, and Arabian (Saudi Arabia) populations.
