Introduction: With the average longevity in men and women, sexual health concerns have become more and more important and demands for help are far more common than in the past. The percentage of aging population is increasing also. A metabolic and hormonal change occurs in male during aging.The level of total, free and bioavailable testosterone decline with aging and it leads to decrease in sexual activities, metabolism and also the life quality.The aim of this initial study was the determination of free testosterone and bioavailable testosterone and it was the novelty of our study. Data obtained from our research can be used as basic information for hormone replacement therapy in late onset hypogonadism.Research goal: To study the free testosterone and bioavailable testosterone level in aging malesMaterials and Methods: This study is a part of study: “Androgen status of aging males” which was supported by Asian Research Center, Korean Foundation for Advanced Studies. The study was approved by IRB of MoH and written consent was obtained from all participants.Fasting blood samples were collected in the morning between 8.00-10.00 AM. We used commercial ELISA kits from Magiwel CoLtd (USA) for determining the total testosterone, sex hormone binding globulin levels. Bromcresol green method was used in determination of serum albumin level. Bioavailable and free testosterone were calculated by Alex Vermeulen, Lieve Verdonk and M. Kaufman’s formula, which was recommended by International Society for the Study of Aging Male.We studied 114 healthy males aged above 40 years old, all undergone the General and Urological examination.Result and discussion: The average age was 57.48±10.48 years in our study participants. In group of 40-49 years were 29% (n=33), in 50-59 age group 23% (n=26), in 60-69 age group 27% (n=38) and in age group over 70-s were 15% (n=17).Mean total testosterone was 6.04±1.83 ng/ml, in 40-49 age group it was 6.14±1.65 ng/ml, in 50-59 age group 6.04±2.36 ng/ml, in 60-69 age group 6.05±1.80 ng/ml, and over 70’s it was 5.85±1.43 ng/ml.Mean sex hormone binding globulin was 50.22±29.97 nmol/l, in 40-49 age group 37.60±23.03 nmol/l, in 50-59 age group 47.08±29.61 nmol/l, in 60-69 age group 57.24±33.91 nmol/l, and over 70’s it was 59.22±25.38 nmol/l.Mean albumin was 40.86±6.89 g/l, in 40-49 age group 44.55±5.93 g/l, in 50-59 age group 41.85±6.93 g/l, in 60-69 age group 38.92±6.85 g/l, and over 70’s was 36.55±4.77 g/l.Mean free testosterone was 0.112±0.064 ng/ml, in 40- 49 age group 0.124±0.058 ng/ml, in 50-59 age group0.114±0.077 ng/ml, in 60-69 age group 0.107±0.072 ng/ml, and over 70’s it was 0.097±0.044 ng/ml.Mean bioavailable testosterone was 2.53±1.48 ng/ ml, in 40-49 age group 2.76±1.37 ng/ml, in 50-59 age group 2.60±1.70 ng/ml, in 60-69 age group 2.51±1.56 ng/ml, and over 70’s it was 2.04±1.05 ng/ml.Conclusion:1. In our participants aged above 40 years old, the average mean of free testosterone was 0.112±0.066 ng/ml, free testosterone index was 16.95±11.82. Free testosterone had inverse correlation with aging (r=-0.168, p=0.03) and had peer decline among aging groups.2. The average mean of bioavailable testosterone was 2.53±1.48 ng/ml, and had age related inverse correlation (r=-0.169, p=0.037), which decline was deeper in men aged over 70 years.Key words:Aging, total, free, bioavailable testosterone,free testosterone index

Introduction:
A drugstore runs its activities in the framework of the primary goal of providing quality guaranteed, high-treatment satisfaction, and safe drugs and medical devices uninterrupted access to pharmaceuticals at retail prices. Pharmacists and chemists, doctors, medical professionals, and consumers will also be involved in promoting the rational use of drugs in the community.
It is practical to study the role and involvement of components in the rational use of drugs.
Method:
Processes and concludes using a one-moment model using a questionnaire survey method.
Conclusion
51.2% of the respondents for the questionnaire survey were 31-40 years old, 80% were women, and 20% were men. 82% of the respondents have a higher education degree.
According to the survey, 61.8% of respondents answered that there are long queues to see a doctor, 79.5% of them responded like pharmacists provide good enough instruction for the use of drugs, 66.4% of respondents aware of the rational use of drugs, and 78.5% of them buy prescribed antibiotics under the prescription from pharmacies. The response shows that the knowledge and information on the rational use of drugs among the population are improving.
According to a survey among physicians, 36.8% of the total number of physicians examines 21- 30 people, 47.4% prescribe prescriptions for 11-20 people per day, 42% gives instructions to their clients on the medications they prescribed, and 42% spends 6-10 minutes for a single client, and 63.2% recommends antifungal drugs when prescribing antibiotics. It shows that the number of people per doctor meets the norms and standards specified in the joint orders of the Minister of Labor and Social Welfare and the Minister of Health dated 30 May 2019 A / 185 and A / 252.
According to a survey of pharmacists, 42.1% of pharmacists surveyed spend an average of 3-5 minutes per customer, 89.5% do not prescribe drug prescription, 88.9% regularly advise their clients on the rational use of drugs, and 78.9% dispense medicine necessarily by prescription. The response to mandatory prescriptions indicates that the requirements of prescription and prescription standards are partially met, indicating the need further to improve the implementation of relevant standards and regulations.

Introduction: With the increasing longevity in men and women, sexual health concerns have become more and more important and demands for help are far more common than in the past. The percentage of aging population is increasing also. The of this study in aging men. Late onset hypogonadism will need the testosterone replacement therapy and we hope that our study result will help to get basic information of testosterone among over 40 yearsold Mongolian men.Goal: To determine the bioavailable testosterone (BT) of aging males and correlate with aging process.Materials and Methods: This study is a part of ongoing study: “Androgen status of aging males” which was supported by Asian Research Center, Korean Foundation for Advanced Studies. We studied 114 healthy males aged above 40 years old, all undergone the General and Urological examination. Bioavailable testosterone was determined by formula suggested by ISSAM.Result: The average bioavailable testosterone level was 2.53±1.48 ng/ml, in 40-49 age group 2.76±1.37 ng/ml, in 50-59 age group 2.60±1.70 ng/ml, in 60-69 age group 2.51±1.56 ng/ml, and over 70’s it was 2.04±1.05 ng/ml. If consider the bioavailable testosterone 100%, in 40-49 age than it is decreasing 94.2% in 50-59, 90.9% in 60-69 ages and 73.9% decreased in over 70s. Respectively, it decreases approximately by 0.9% every year after 40’s.Conclusion: The bioavailable testosterone level was 2.53±1.48ng/ml in aging males and has reverse correlation with aging (r=-0.169, p=0.037).

Introduction: It is significant to translate medical texts having a beginning source of Ayurveda and identifyMongolian doctors, maaramba’s works and books on prescription as well as treatment methods that meetour culture, living condition and climate. Especially, we should clarify the new ideas includes innovatedtheories, which became paradigm not only Traditional Mongolian Medicine but also in Tibetan Medicine.Thus, it has become important to introduce and use in the training for students and practitioners the “FourAmbrosia Essences” and “Dictionary of Drug Identification” by Sumbe Khamba Ishbaljir (1704-1788).Goal: The aim of this study is to investigate “Four Ambrosia Essences” and “Dictionary of Drug Identificationby Sumbe Khamba Ishbaljir and to clarify the new idea of theory and treatment methods created by him.Materials and Method: “Source of Spring” (བདདུ ་ར་ིྩ ཆ་ུ རནུྱྒ ), “White Dew of Spring” (བདདུ ་ར་ིྩ ཟལི ་དཀར), “Drop of Spring”(བདདུ ་ར་ིྩ ཐགི ་པ), “Wedding of Spring” (བདདུ ་ར་ིྩ དགའ་སནོྟ ” by the Sumbe Khamba Ishbaljir were the main materials in thisstudy. In addition, we used to take some sort of sources and manuscripts that related to our studies andcomparative historical method, analysis and synthesis method were used in the studies.Results: According to resources we found, Sumbe khamba Ishbaljor detailed a number of new theoreticaland practical concepts which were never or seldom mentioned in The Four Medical Tantras, in his bookRashaany Dusal (“Drop of Spring”). He expanded the list of common diseases from three wind (khii), bile(shar), phlegm (badgan) to 6 (wind, bile, phlegm, blood, yellow fluid (shar us), nyan or khorkhoi (virus andbacteria) and prescribed treatments for each of them. In addition, he established a concept of 10 importantdiseases and gave them satiric names making them easy to read and understand as well as taught theways to treat them.Ishbaljir developed the traditional medicine and made a reform in it by the discovery of three more causesof diseases blood, bile us and bacteria in addition to the existing causes wind, bile and phlegm. His theorywas that disease causes are wind, bile, phlegm, blood, yellow fluid, and bacteria or virus individually and\or combined. Wind, bile, phlegm, blood, yellow fluid, and bacteria or virus called as diseases. Ishbaljir’sconcept of bacteria duplicates that of some Noble Prize laureates. At the beginning of the 20 century, anAustralian scholar Barry J. Marshall and J. Robin Warren won the Noble Prize for their discovery of the“Bacterium Helicobacter pylori and its role in gastritis and peptic ulcer disease” in 2005.Conclusions:1. Sumbe Khamba Ishbaljir expanded the list of common diseases from 3 wind (khii), bile (shar), phlegm(badgan) to 6 (wind, bile, phlegm, blood, yellow fluid (shar us), nyan or khorkhoi (virus and bacteria)and prescribed treatments for each of them.2. Sumbe Khamba Ishbaljir established a concept of 10 important diseases and gave them satiric namesmaking them easy to read and understand as well as taught the ways to treat them.3. The Four Medical Tantras did not mention stomach bacteria. It is pity that Sumbe Khamba Ishbaljirfound out the stomach bacteria disease in the 18th century.

The research on the smoking habits among 8th-to-12th grade students of schools was conducted using a random sampling method among the 13-18 years old school students.Materials and MethodsThe research was performed using a combination of both qualitative and quantitative methods. The quantitative part of the research was performed by conducting surveys among randomly selected secondary school students according to prepared and approved questionnaires. The qualitative study was performed by organizing focus groups based on prepared discussion guidelines. Sampling: the survey participants were students in grades 8-12 from both public and private schools in Ulaanbaatar, the capital city of Mongolia. A total of 1190 students from the 12 secondary schools of 6 districts were selected through random sampling.Resultsto the question of whether the participants have tried to smoke once or twice, 36,1% (407) responded positively. Among these respondents, 49.6% (272) are male and 23.2 (135) are female. This confirms the statistical data that male students are more exposed to the habit of smoking than female students (x2=57.8, p<0.01). The percentage of the currently smoking students is 11.2% (77) of whom 17.9% are male and 4.8% are female. Of the current smokers, 6.8% smoke every day (x2=48.3, p<0.01). The average age of taking up smoking was 14.0[±1.8] of which males students began using tobacco at 13.9[±1.8] years and females at 14.3[±1.6]. Among the smoking students, 10[±2.1]% were from public schools and 17.3[±2.8]% were from private schools (x2=8.1, p<0.01).

Introduction: Erectile dysfunction (ED), also known as impotence, is defined as a consistent or recurrent inability to attain and/or maintain penile erection sufficient for sexual performance [1]. According to recent study results, ED occurs more than 50% over 60 year old males, emphasizing a need to diagnose and treat it at an earlier stage. ED may be assessed in several ways. The most widely used standardized questionnaire is the International Index of Erectile Function (IIEF) with 15 questions, which also exists in a short form with 5 questions [2]. On the other hand, ED is associated with a decreased level of androgens in aging males; the latter is often referred to as a Late Onset Hypogonadism (LOH) or Testosterone Deficiency Syndrome (TDS). In simple terms, LOH or TDS can be defined as a decreased serum testosterone level in aging males [3, 4]Objective: To detect the testosterone deficiency syndrome in aging males with erectile dysfunction. Materials and Methods. 309 males over 40 years of age who received medical care at the ADAM urological and andrological clinic from 2010 to 2011 were included in this study. An approval of the Ethical Committee of MOH was obtained at the commencement of the study. Each study participant signed a consent form at the beginning of the study. Each participant was assigned to either an ED group or a control group depending on results of the IIEF-5 questionnaire. The ED group was further divided into three groups (moderate, severe and very severe) based on a level of ED. The total testosterone (TT) levels were determined in blood serum, using a competitive ELISA analytical system UBI MAGIWELTM TestosteroneQuantitative test (GLS, USA), with C.V. (%) 6.8 and free testosterone (FT) calculated as described by Vermeulen. Test samples were collected between 8.00-11.00 am. The biochemical diagnosis of TDS was based on the Study Aging Male (ISSAM) guidelines of the International Society, particularly, if TT was _3.46 ng/ml or free testosterone FT was ≤0.072 ng/ml [5].Results: ED of moderate, severe and very severe levels were diagnosed in 199 (64.41%) out of 309 participants. There was an inverse association between an erectile function and age (r=-0.380, p <0.01). The average TT was 5.75±2.316 ng/ml and FT was 0.091±0.0084 ng/ml. Compared to the ED group, the control group had a higher TT level: 5.6440±1.177 ng/ml and 5.812±2.316 ng/ml respectively. In the control group the FT level was 0.061±0.0084 ng/ml whereas it was 0.041±0.0076 ng/ml in the ED group. Conclusion: Our study showed that most of aging males who came to the clinic had a moderate to very severe ED (64.55%). The level of TT (5.644±1.177 ng/ml) and FT (0.041±0.0036 ng/ml) was significantly lower in ED patients (p<0.05). The testosterone deficiency syndrome was detected in 24.27% of the ED group.
8.Review on phytochemical composition and biological activity of Saxifraga L.
Mongolian Pharmacy and Pharmacology 2023;23(2):12-19
Abstract
The genus Saxifraga, one of the largest genera of the Saxifragaceae family, comprises
465 species and is distributed widely in mountainous and rocky regions, with 12 species being
found in Mongolia. In Asian folk medicine, numerous wild-collected Saxifraga species are used
to treat different disorders, including cancer, headache, hemorrhoids, influenza, liver diseases,
neuralgia, phthisis bulbi. and tympanitis. Moreover, the aerial parts of S. spinulosa are used in
Russia and the Tibetan plateau to treat conjunctivitis, gynecopathy, and diseases of the larynx.
Since 1970's, chemical constituents of Saxifraga species started to be studied. Currently, about
150 secondary metabolites from more than 23 species were isolated and their structure elucidated, including flavonoids, phenolic compounds, triterpenes and steroids, and other class of copmpounds. Extracts and isolated pure compounds from Saxifraga species showed antioxidants and
hepaprotective, anticancer and inhibitory activities against Babesia and Theileria parasites.

Mongolian Medical Sciences 2024;207(1):8-14
Introduction:
The last decade has seen a dramatic increase in general interest in and research into vitamin D, with
many athletes now taking vitamin D supplements as part of their everyday dietary regimen. The most
recognized role of vitamin D is its regulation of calcium homeostasis; there is a strong relationship
between vitamin D and bone health in non-athletic individuals. Vitamin D is responsible for regulation
of calcium and phosphate metabolism and maintaining a healthy mineralized skeleton. It is also known
as an immunomodulatory hormone. Experimental studies have shown that 1,25-dihydroxyvitamin D,
the active form of vitamin D, exerts immunologic activities on multiple components of the innate and
adaptive immune system as well as endothelial membrane stability. Studying the level of vitamin D in
athletes in relation to age group, body mass index, and type of sport is important for reducing the risk of
injury and infection in athletes and improving performance and success in sports.
Goal:
To determine the 25-hydroxyvitamin D [25(OH)D] levels in the plasma of the trained athletes and their
vitamin D status to compare of their sports type.
Materials and Methods:
Sample size
Using a cross-sectional design, a total of 71 athletes aged 20-43 from the sports medicine research
center and the national team was selected by sampling.
Method of the Laboratory analyses
The body mass index and blood plasma level of 25 hydroxy vitamin D of the athletes participating in the
study were compared by sports type and analyzed using descriptive statistics. Comparison of survey
data was performed using Pearson’s correlation method.
Results:
In the study, 71 athletes of the Mongolian national team participated in 5 types of sports. Descriptive
analysis was performed on the general parameters of the athletes, body mass index, type of sport, level
of vitamin D in the blood, etc.
An avarege level of vitamin D of the athletes who participated in our study were 22.27±12.9 ng/ml, in the age group of 20-29 years, and compared to the body mass index, it was the highest level in the athletes of normal weight.
Conclusions
1. The level of vitamin D of the athletes who participated in our study was the highest in the age group
of 20-29 years, 22.27±12.9 ng/ml, and compared to the body mass index, it was the highest level
in the athletes of normal weight.
When studying the level of vitamin D of the participants in comparison with the type of sport, the
freestyle wrestlers had a higher level of 34.75±15.13 ng/ml, while the judo wrestlers had a lower
level of 12.69±5.17 ng/ml.

Mongolian Medical Sciences 2024;208(2):8-12
Introduction:
The average age of the population varies in every country of the world, which depends on the changes
that occur in the body during aging and many external and internal factors that affect it. Thyroid
hormones play an important role in ensuring and maintaining normal metabolic function throughout
life. Our country is located in a mountainous region of the mainland, the amount of iodine in drinking
water is low, and the amount of iodine taken from food is low, which creates the risk of iodine deficiency
disorders. Therefore, we aimed to study how the thyroid function changes with age in Mongolian
people.
Goal:
A comparative study of thyroid hormone secretion levels in adult women.
Material and Method:
In our study, 83 women over the age of 20 were selected based on the “Yu Bi Lab” diagnostic center.
Triiodothyronine (T3), thyroxine (T4), and thyrotropin (TSH) of the women participating in the study
were determined using the FHU method using the Magiwel ELISA diagnostic kit manufactured by
United Biotech.
Results:
81 women over 20 years of age participated in our study, the average age was 44.45±14.17, and the
participants were divided into 5 groups with 10 age intervals. 20-29 years 18% (n=15) average age
24.6±2.64, 30-39 years 22% (n=18) average age 33.6± 3.12, 40-49 years 16% (n=13) average age
45.15±1.67, 50-59 years 25% (n=20) average age 54.15±2.99, 60-69 years 19% (n=15) average age
63.73± 3.05, were.
Conclusion
1. When comparing T3 and T4 hormones by age group, T3 hormone is higher in the 30-39 age group
at 5.05 ng/ml. The T4 hormone gradually decreases with age.
2. Thyroiodin hormone increased with age. The relationship between the age of the participants
and TSH hormone was directly related to statistical age when calculated by Pearson’s correlation
coefficient (p=0.01).
