BACKGROUND. As long ago times or perhaps longer, people were using insects as medicines for healing wounds, preventing infections and improving health. Some of these are purely anecdotal, while others have proven basis in fact as tested by modern medicine.Usage of insects intraditional medicine was recorded since time immemorial.Insects and their substances have been used as medicinal resources by different cultures since ancient time because of chemical compounds - e.g. pheromones, defensive sprays, venoms and toxins, which were sequestered fromplants or prey and later concentrated or transformed for their own use.In many parts of the world,different sections of the society have been using medico-entomological drugs to this day in their lives.A numberof studies has in recent years drawn attention to thetherapeutic value of certain species of insects, their products, and their developmental stages.As has been documented insects can be a source of drugs used in modern medicine, since compounds of insect origin can have immunological, analgesic, antibacterial, diuretic, anaesthetic and anti-rheumatic, antitumor properties. Numerous insect originated materia medicain Mongolian traditional medicine contribute this source of therapeutics and variety of ancientmedical treatises by local authors as well as translations of renowned Ayurvedic medical books about animals as medicine exist.Knowledge about therapy with insects in Mongolian traditional medicine is less studied even they have been used broadly since ancient time. Several orthodox practitioners have surveyed the therapeutic potentials of defensive agents in dark beetleknown as “stink beetle” in the past.Yet the scientific community has to give thismajor and crucial component of traditional Mongolian medicine the attention it deserves, scientific knowledge about biologically active principles within medicinal insect remain poorly unknown.

Since anatomist and doctor Andreas Vesalius (1514-1564) knew that a thorough knowledge of human anatomy was essential to surgery, he devoted much of his time to dissections of cadavers and insisted on doing them himself, instead of relying on untrained assistants. As a result, he created his famous work called “De humani corporis fabrica libri septem” in 1543. This creation was evaluated as scientific discoveryin Europe.
Two hundred forty years later, Dominique Parennin (1665-1741)wrote the book “ManchuAnatomy”by the order of Kangxi Emperor (1654-1722). Thebook was written by hand and the Kangxi Emperor was given three copies. The whole name of the “Manchu Anatomy”is «Imperially-Commissioned Complete Record on the Body. Unfortunately, the Kangxi Emperor did not allow the publication of the book. It was indeed sad that Kangxi Emperor, who distinguished himself by his unusual intelligence and was noted for his encouragement of the arts and sciences, failed to perceive the importance of the «Manchu Anatomy». Had it been printed and disseminated it certainly would have revolutionized Chinese medicine, as Vesalius› «De humani corporis fabrica libri septem” did for European
medicine.
However, Dominique Parennin has sent another special copy to the Royal Academy of Science in Paris, which he was a corresponding member. In a letter dated May 1, 1723 accompanying the «Manchu Anatomy» he wrote in old French: Vous serez peut-etre surpris que je vous envoye de- si loin un traite d›Anatomie, un corps de Medecine, et des questions de Physiques ecrites en une langue, qui, sans doute, vous est inconnue; mais votre surprise cessera quand- vous verrez que ce sont vos propres ouvrages que je vous envoye habilles a la Tartare. Oui, Messieurs, ce sont vos pensees et vos ingenieuses decouvertes. In this study, we have translated this letter into Mongolian and explained the content of letter. Thanks to this book, in Europe and America, the book is known as the Manchu
Anatomy, and many researchers published several books and scientific articles about the book. However, there is no one who has found that this book has been translated into Mongolian except the Manchu language. Our next study is to compare the Manchus and the Mongolian texts of this book.

Introduction:
Khuumii (throat singing) is a unique form of art derived from the nomadic population of Central Asia,
producing two or more “simultaneous” sounds and melodies through the organ of speech.
Material and Methods:
The aim of the study is to identify the anatomical structures involved in the formation of khuumii
and the features and patterns of their functions and compare each type of khuumii as performed by
Mongolian people. A total of 60 participants aged 18-60 years (54 men and 6 women) were selected
by non-random sampling method using cross-sectional study. Statistical analysis was performed
using SPSS 23 software using questionnaires, X-ray, endoscopy, sound research method, and
general blood tests.
Results:
90.7% of the khuumii singers were male and 9.3% were female. The average height of the participants
was 172.91±0.93 cm (arithmetic mean and mean error), average body weight was 77.53±2.46 kg,
and body mass index was 25.93±5.31 respectively. Heart rate was 92.19±20.71 per minute prior to
khuumii while 133.19±19.09 after performing khuumii and 85.81-98.56 at 95% confidence interval. In
terms of ethnicity (ethnographically), the Khalkh were the largest ethnic group (72.1%), followed by
Bayad, Buryatia, Darkhad, Torguud, and Oirat (2.3%), respectively. 60.5% of the participants were
professional khuumii singers who graduated from relevant universities and colleges. The process of
Khuumii was recorded by X-ray examination, and laryngeal endoscopy evaluated the movement of
true and false vocal chords, interstitial volume, movements of epiglottis and arytenoid cartilage, and
mucosa. Khuumii increases the workload of the cardiovascular system by 70-80%. Furthermore, the
sound frequency is 2-4 times higher than that of normal speech, and sound volume is 0.5-1 times
higher. 95.3% of throat singers did not have a sore throat, 88.4% did not experience heavy breathing,
and 74.1% had no hoarseness. During the formation of khuumii sound, thoracic cavity, diaphragm,
and lungs regulate the intensity of the air reaching the vocal folds, exert pressure on the airways and
vibrate the sound waves through air flows passing through the larynx and vocal folds. Mouth-nose
cavity as well as pharynx are responsible for echoing the sound.
Conclusion
It is appropriate to divide khuumii into two main types according to structural and functional changes
in the organs involved; shakhaa and kharkhiraa. Khuumii, the “Human music” originating from the
people of Altai Khangai basin by imitating the sounds of nature with their own voice in ancient times,
spread all over the world from Mongolia and it is proposed to classify khuumii into two main types of
shakhaa and kharkhiraa in terms of structural involvement and functionality.

Background:
Hyperferritinemia, characterized by elevated serum ferritin levels, affects approximately 5–25% of the general
population. Given the frequent coexistence of liver iron overload syndrome and metabolic syndrome—both of which
significantly contribute to global morbidity and mortality—it is essential to investigate their interconnections. However,
there is a lack of sufficient evidence, both in Mongolia and internationally, regarding the relationship between iron storage
indicators, metabolic syndrome, and its components. A deeper understanding of iron’s role in disease progression is
needed.
Aim:
This study aims to assess the association between hyperferritinemia and metabolic syndrome parameters.
Materials and Methods:
A cross-sectional analytical observational study was conducted on 159 male participants who
met the inclusion criteria. Data were collected using a standardized questionnaire, and anthropometric measurements
were taken. Blood samples were analyzed to determine glucose, triglyceride, total cholesterol, and high-density lipoprotein
(HDL) levels using an automated biochemical analyzer. Serum ferritin concentrations were measured via the ELISA
method (DRG Instruments GmbH, Germany), with hyperferritinemia defined as a serum ferritin level exceeding 400 ng/
ml. Metabolic syndrome was diagnosed based on the Harmonized criteria. Statistical analyses included the chi-square
test and Fisher’s exact test for categorical variables, the Mann-Whitney U test for non-normally distributed data, and
Spearman’s correlation test to assess relationships between glycemic levels, lipid parameters, and metabolic syndrome
components.
Results:
The findings indicate that 59 participants (37.1%) had metabolic syndrome, while 33 (20.8%) presented with
hyperferritinemia. The presence of metabolic syndrome and hyperglycemia increased the likelihood of developing hyperferritinemia
by 3.4 and 3.7 times, respectively, whereas abdominal obesity raised the risk by 2.2 times.
Conclusion
There was a significant correlation between serum ferritin levels and certain parameters of metabolic syndrome
among the male participants in this study.

Background:
A 2018 study on the global burden of disease, accidents, and risk factors reported that 1.6 million peo
ple died in 2017 due to household air pollution. Poor indoor air quality has been highlighted as a contributing factor to
respiratory diseases, cardiovascular conditions, and exacerbation of asthma and allergies. A 2019 study estimated that
long-term exposure to fine particulate matter (PM2.5) with a diameter of 2.5 micrometers or less reduces average life
expectancy by 1.8 years, with more severe effects in highly polluted regions. Additionally, a study by Miller et al. (2007)
found that prolonged exposure to PM2.5 increases the risk of cardiovascular diseases, particularly among women. Direct
measurement devices are highly effective in determining indoor PM2.5 concentrations, identifying sources of pollution,
tracking pollutant dispersion, and monitoring temporal variations. Studies suggest that direct measurement is an accurate,
cost-effective method that provides detailed data suitable for local conditions.
Aim:
To investigate the indoor air quality of houses and apartments in Darkhan city during the winter season using the
Purple Air monitoring device.
Materials and Methods:
A cross-sectional study was conducted with a targeted sample of 128 households in Darkhan
city. The study examined factors such as stove type, type of coal used, annual and daily coal consumption, frequency of
heating, and chimney sealing conditions. To collect data, the Purple Air monitoring device was installed in each house
hold for a month, after which it was retrieved. During retrieval, participants completed a questionnaire. The questionnaire
consisted of 55 questions across 7 pages at the time of device installation and 25 questions across 3 pages at the time of
device retrieval. The collected data was analyzed using SPSS 25.0.
Results:
A total of 128 households in Darkhan city participated in the study. The average duration of residence in the
current home was 9.5 years, with no statistically significant variation. The distribution of housing types was as follows:
traditional Mongolian gers (40.6%), houses (39.1%), and apartments (20.3%). The 24-hour average PM2.5 concentration
was highest in gers (70.9 μg/m³), followed by houses (46.8 μg/m³) and apartments (22.8 μg/m³), with a statistically significant difference (p=0.0001). PM2.5 levels were most variable in gers, followed by houses and then apartments. House
holds using central heating (apartments) had an average 24-hour PM2.5 concentration of 22.8 μg/m³, whereas households
using stoves (gers and houses) had a significantly higher concentration of 59.4 μg/m³ (p=0.0001). However, there was
no statistically significant difference between traditional and improved stoves. Among study participants, 21.4% reported
that someone in their household smoked indoors. Additionally, 86.5% regularly burned incense, candles, or herbs, while
99.2% did not use an air purifier.
Conclusion
The indoor particulate matter concentration in houses and gers in Darkhan was 59.4μг/m3. Variations in
stove types, poor chimney sealing limited space, and frequent gaps and cracks contribute to increased spread of indoor
air pollutants.

BACKGROUND: Toll like receptors (TLRs) are a class of proteins that key role in the innate immune system. TLR7 is expressed on monocytes, macrophages and dendritic cells, T cell, B cell and eosinophiles. TLR7, originally identified as recognizing imidaquinoline, loxibrine, broprimine and ssRNA, ssRNA viruses such as vesicular stomatitis virus, influenza A virus and human immunodefiency virus. It is known that virus ssRNA affects signaling molecule of IFN-y. Objective: To determine gene and protein activation of IFN-y signal transduction by TLR7 ligand in the endothelial cells.
MATERIAL: In study we used mouse aortic linear endothelial cell which is cultured (END-D) in 5% heat- inactivated fetal calf serum (FCS), medium (DMEM) containing antibiotic mix(penicillin G, streptomycin, amphotericin B) at 37°C (5% CO2). Endothelial cells treated with synthetic IFN-γ and imiquimodligands, then the NO (nitric oxide) concentration in the supernatant is determined by Griess reagent. Endothelial cells are cultured in 6 well cell culture plate and in each well 2*104cells are expected to be grown for 24 hours of culture. Then, the cells are treated with synthetic IFN-γ and имиквимод ligand for 6 hours and the NO signaling gene activation iNOS mRNA expression which is induced by IFN-γ is determined by RT-qPCR. Endothelial cells are cultured in 12 well cell culture plate and in each well 2*104 cells are expected to be grown for 18 hours of culture. Then, the cells are treated with synthetic IFN-γ and imiquimodligands for 24 hours and the NO signaling protein iNOS expression which is induced by IFN-γ is determined by western blotting. The experiment was conducted as representation mean of at least three test results. The difference between statistical probabilities is determined by the “Students” t test. The p<0.01 value is assumed to be statistically different.
RESULTS: TLR7 ligand imiquimodaugmented interferon gamma induced nitric oxide production TLR7 ligand imiquimodincreased interferon gamma induced iNOS mRNA gene expression. TLR7 ilgand imiquimodup-regulated interferon gamma induced iNOS protein expression.
CONCLUSIONS: TLR7 ligand imiquimod augments IFN-γ signaling in the endothelial cells. This synergistic effect has revealed in the levels of gene and protein expression.
