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

Mongolian Pharmacy and Pharmacology 2021;19(2):100-108
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.

INTRODUCTION:Waterborne diseases, especially diarrhea, related to water quality and safety, personal sanitation and hygienehave been still reported very high in developing countries. Globally, there are an estimated 1.4 million casesof hepatitis A every year. The hepatitis A virus is transmitted through ingestion of contaminated food and wateror through direct contact with an infectious person. Hepatitis A is associated with a lack of safe water and poorsanitation [2].Dysentery is bloody diarrhea, i.e. any diarrheal episode in which the loose or watery stools contain visiblered blood. Dysentery is most often caused byShigella species (bacillary dysentery) or Entamoeba histolytica(amoebic dysentery) [3].Kharaa and Orkhon River are tributaries of the Selenge River-basin, in which many mining and other industries,agriculture, and residential areas reside. It has become a one pollutant factor for water of the Kharaa andOrkhon rivers. As a result, water of the Tuul, Kharaa and Orkhon River was reported to be highly contaminated(Mongolian Human Development Report 2010: Water and Development report) [4].GOAL:The aim of the research was to study incidence of gastrointestinal infectious diseases among population ofsoums are located in Selenge River Basin.MATERIALS AND METHODS:Data on health statistics 2009-2013 years of gastrointestinal infectious diseases, including dysentery, diarrhea,hepatitis A virus and others, were collected and analyzed.RESULTS:Incidence of dysentery was registered highly among people who live in Mandal soums in 2009-2013 years. Butincidence of dysentery (per 10 000 population 2.82) among population ofMandal soum lower than the Selengeprovince and National average. Incidence of hepatitis A virus was registered highly among people who livein Orkhon (74.46), Orkhontuul (48.86) soums and it was greater than 1.3-2 times than the Selenge provinceaverage. Incidence of diarrhea was registered highly among people who live in Khushaat soum and it wasgreater than 2.18-3.8 times the than Selenge province averageCONCLUSION:Incidences of diarrhea and hepatitis A virus were registered highly in Orkhon, Orkhotuul and Khushaat soumscompared to other target soums and it was greater than 1.3-3.8 times than the Selenge province average.Especially, these diseases were registered highly among 0-16 aged children.

Background: Discrepancies in the sensitivity to biological effects of the androgens, exerted through the binding of the hormone to the androgen receptor (AR), may also be involved in the inter-individual variation of T as well as in age related decline. The human androgen receptor (AR), located on chromosome Xq11-12, is a transcription factor regulating the development of male reproductive organs in the fetus and secondary sex characteristics at puberty in response to testosterone (T) and 5a-dihydrotestosterone (DHT). The AR contains two polymorphic regions, the (CAG)nCAA repeat encoding polyglutamine, and the (GGT)3GGG(GGT)2(GGC)n repeat encoding polyglycine, commonly referred to as the CAG and GGN repeats respectively. The aim of this study is to investigate the effect of the human androgen receptor genes CAG and GGN repeat polymorphisms in relation with androgen level.Materials and Methods: Sample collection: 180 male, the medical data of these volunteers were obtained and determined some androgen hormones at first phase of study in 2010-2011 (total testosterone (TT), free testosterone (FT) and bioavailable testosterone (BAT)). To determine CAG/GGN repeats length in exon of androgen receptor gene, using frozen serum as a source of deoxyribonucleic acid (DNA). DNA was extracted from blood samples (200 ml) using High PurePCR Template Preparation Kits.Results: The 180 men whose age is at least 40 were involved in our research and their average age was 55.1±10.3. The 46.7% (84) of the participants presents CAG gene, the 6.1% (11) of the participants presents GGN gene while the 25.5% (46) of the participants presents both CAG and GGN genes. However, the 21.7% of 39 men not presents CAG and GGN genes.Conclusion: The free testosterone level was significantly decreasing with aging. However, the appearance of CAG gene polymorphism was significantly higher in more aged people. Decline of free testosterone level in participants with CAG and [CAG+GGN] combined form was stronger than in people with GGN gene polymorphism and CAG, GGN both undetected people. But the level of bioavailable testosterone was decreasing with aging and the appearance of CAG gene polymorphism (r=-0.425, p=0.01) and [CAG+GGN] combined form (r=-0.491, p=0.028) was also increasing.
