Introduction: Factors such as social and economic conditions, technological development, modern urbanization, lifestyle, physical activity, nutrition, and air pollution affect physical growth and development. Aim: To study the physical development of Mongolian children. Objectives: 1. To measure the physical indices (weight, height) of children aged 6-17 years old with some influencing factors. Material and method: Using a random sampling method, children's body height and weight were examined at a particular point in time using widely accepted methods. Statistical analysis was performed using the "SPSS ver.25" program. Result: The growth of children's height and weight is progressing according to general patterns of age and gender. Girls grow rapidly between the ages of 10-13 and stabilize after wards, while boys a sharp growth spurt between the ages of 13-17, with the average height of 17-year-old boys being 171.44 cm and 160.25 cm for girls, which is slightly higher than previous studies (Otgon G, 2006, Munkhzaya M, 2020). The trend of weight growth is more prominent in boys. However, compared to international standards (Russia, WHO, CDC), our children's height and weight are lower. The statistics show that parental education, income, exercise, and living environment positively influence growth and development, whereas excessive television watching and air pollution negatively affect it (p< 0.05). Conclusion 1. Children's growth is normal, but observed increase of the body weight of boys. Having healthy and well educated parents, as well as engaging in physical activity positively influences children's height. A lack of physical activity negatively affects height and increases weight. Mongolian children are shorter and lighter compared to foreign children (from Russia and America - CDC).

Introduction: In 2018, the overall colorectal cancer (CRC) incidence rate was 3.6%, according to the National Cancer Center of Mongolia (NCCM), and the incidence of colorectal cancer has increased slightly in recent years. According to cancer stages, late stage cancer has a 5-year survival rate of 51%, while early stage cancer has a 5-year survival rate of 79%. The overall survival rate of colorectal cancer in Mongolia has not been studied in precisely. In Asia, the 5-year survival rate for colorectal cancer was 60%. Therefore, this study investigated the colorectal cancer survival rate and prognostic factors at NCCM. Methods: A total of 108 patients diagnosed with CRC at NCCM’s General Surgery Department from 2013 to 2015 were used in this retrospective cohort study. The Kaplan-Meier method was used to develop the survival graphs, which were then compared using the Log-rank test. Results: The median survival time was 42 months, with a 95% CI (38.55-45.66). A 5-year period, the overall survival rate for CRC was 61.2%. Survival rates at the I, II, III, and IV stages were 100%, 75%, 65.4%, and 13.5%, respectively. There was a significant difference in CRC survival rates across all stages (p=0.0001). There was a statistically significant difference in determining the relationship between adjuvant chemotherapy and survival rate (p=0.0003). Conclusion The outcome of the surgery is determined by the CRC stage. The postoperative survival rate (61.2%) is directly related to tumor stage, peripheral glandular metastasis, distant metastasis, and chemotherapy effects.

Background: Early application of autologous skin may lead to the loss of split thickness skin graft due to unclarified wound bed. Allogeneic skin grafts are performed on patients with extensive burn injuries after escharotomy, tangential excisions and deep debridement for the purpose of stabilizing the general condition and reducing the scope of local complications. Objectives: The aim of this paper is to determine how the use of allografts improves the conditions for the intake of autografts in burns treatment, and how it accelerates wound healing in comparison to the autografts-only option. Material and Methods: In 2016-2017, allogeneic skin was grafted on 24 patients, and in 6 cases grafting was repeated several times. An autologous split-thickness skin graft was applied to 23 patients. The analysis included the relationship between the duration of hospitalization and the number of skin transplantations, the relationship between the time of admission to debridement of the necrotic tissues and the total duration of hospitalization. Results: The results suggest that multiple applications of autografts not only do not lead to quicker recovery, but even lengthen the hospitalization time. The dependency is visible also in the patients who underwent the skin grafting procedure in allogeneic and autologous systems twice or more. There was a statistical significant difference between the duration of hospitalization in groups of patients who underwent STSG preceded by allogeneic skin graft transplantation when compared to the group of patients who underwent allogeneic skin application (p < 0.05) and the group of patients who were grafted with autologous skin (p < 0.05). The procedure of early resection of necrotic tissue combined with autologous or allogeneic skin graft improved the survival outcomes of the patients. Conclusions Allogeneic skin grafts are a perfect dressing when wound vascularization is insufficient to take free split-thickness skin graft. In patients with comparable burn surface areas, multiple applications of free autologous split-thickness skin grafts (STSG) extend the hospitalization time in comparison to application of allogeneic skin dressing as the first-line therapy.

Introduction: Sarcopenia is a prevalent condition characterized by decrease in muscle strength and loss of body function which result from the decrease of muscle mass in older age. In 2014, the Asian Working Group for Sarcopenia developed the diagnosis criterion for sarcopenia. The measurements were changed to accommodate for the physical characteristics of asians. The loss of muscle mass increases after age 40 and decreases by 8 percent every 10 years. After age 70 this number is increased to 15 percent every 10 years. Goal: Assess the prevalence of sarcopenia among men by comparing body height and mass Materials and Methods: The study included 196 older men aged 40 and above chosen by random sampling from the geriatric and rehabilitation cabinets of the Mongolian National Gerontology Center.
Sarcopenia diagnosis was made based on the criteria from the Asian Working Group for Sarcopenia using methods by Janssen I and others to compare body mass and height. Results: Comparing body muscle mass and height 11.7 percent of participant aged 40-86 had sarcopenia. When comparing body muscle mass and weigth 33.2 percent had sarcopenia. Conclusion Determining sarcopenia among Mongolian men by comparing muscle mass and body mass resulted in 33.2 percent sarcopenia. When compared with height, 11.7 percent had sarcopenia.

INTRODUCTION:Alcohol (EtOH) use disorders (AUDs) represent a substantial public health problem worldwide. Over 76million people present with AUDs 2.5 million deaths were attributed to alcohol (World Health Organization,2010). Channadshelshi has been used for treatment of alcohol-related, liver disease and intoxication intraditional medicine.GOAL:To determine effect of channadshelshi on voluntary alcoholic wistar rats.MATERIALS AND METHODS:To examine acute toxicity of Channadselshi were used V.P.Prozorovsky express method (1978) andOECD (2001).Voluntary EtoH consumption measurement (two-bottle choice, intermittent access to EtOH paradigm inwistar rats). Water and 20% ethanol were presented in 200 mlgraduated plastic cylinders with stainlesssteeldrinking spouts.The experiment period was 10 weeks total. EtOH consumption was expressed asgrams of EtOH consumed per kilogram of body weight/day.Elevated plus maze. Anxiety associated with EtoH withdrawalwas measured on EPM The mazewaselevated 1 m above the floor and contained four 50 cm long, 10 cmwidearms arranged at rightangles. The closed arms had opaque walls 30cm high, extending the length of the arm. At the time of thetest, eachanimal was placed in the center of the maze facing an open arm andallowed to explore for a5 min session. During this 5 min test session, theanimal’s number of arm entries and time spent in eacharm per entry was recorded on a camera.Pentylenetetrazol (PTZ) 100 mg/kg dose used in this study was determined as the dose that inducedseizures and protection against mortality in miceThe experimental protocol was approved by the Ethics Committee of the MNUMS. (№ 14-11/1À)RESULTS:LD50 of Channadselshi extract was found to be LD50=2.58 (2.1-3.2) gr/kg by V.P.Prozorovsky expressmethod (1978). Channadselshi was no acute toxic by OECD (2001).Ten and four weeks oral administration of Channadselshi (200 mg/kg) significantly (P<0.01) decreasedthe consumption of ethanol and significantly (P<0.01) increased time spent in open arm (EPM) involuntary alcoholic wistar rat compare to control.The time (sec) of latency the generalized convulsion were significantly (P<0.01) increased ofChannadselshi compare to control. The percent of protection against mortality were 80% in PTZinduced seizure in mice.CONCLUSIONS:1. Our study showed that Channadselshi hasreduced consumption of ethanol in voluntary alcoholicwistar rat.2. Channadselshi has central nervous system protection effect against PTZ induced seizure in mice.

Managchenmo is a traditional Mongolian medicine functional liquor comprising twelve crude drugs: Sus scrofa / cinis faecis /, Inula helenium L., Terminalia chebula Retz., Melia toosendan Sieb, Gardenia jasminoides Ellis, Lagotis integrifolia (Willd.)Schischk, Gentiana barbata Froel, Moschus moschiferus, Bezoar Bovis, Calcio sinteris, Carthamus tinctorius L,and Saccharum officinarum. Nowadays the Mongolian traditional herbs are more preferable than the chemical ones; for this reason studies on their use history and new technologies are conducted. Thus we study Managchinmo affects, herb for treatment of liver hot disorders, on trial rats (Handa.S.S, Sharma.A .1990 ) with hepatotoxicity. The levels of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkalinephosphatase (ALP) were determined through biochemical methods. The bile duct was cannulated with a tube to collect bile for two hours and bile flow was calculated by the weight of each specimen. Our results showed that Managchenmo (150 mg/kg) significantly prevented CCl4-induced changes in bile flow and serum levels of ALT, AST, and ALP. In conclusion, Managchenmo exerted a protective effect on CCl4-induced hepatotoxicity in rats.
