Introduction: Prevalence of asthma is increasing year by year, especially among children and exposure to high levels of indoor allergens is a very important factor [1]. Cockroaches are an important cause of asthma in many other regions of the world, including Taiwan, Thailand and Singapore in the Pacific Rim, Costa Rica and Puerto Rico in Centrel America, India, South Africa and more recently, Europe [2]. Goal: The aim of this study was determined total protein amounts allergenic proteins and protein bands of сockroach.Material and Methods: The сockroachs were collected in Ulaanbaatar. The allergenic protein components of the сockroach was purified by the method of Hames Richmond. The total protein of extracts was measured by the Bradford method and the protein components of cockroach were determined by the SDS-PAGE.Results: Among the 4000 known species of cockroaches, only 5 commonly inhabit homes and have the potential to contribute to indoor allergens. These include the American (periplaneta americana), German (Blattella germanica), Oriental (Blatta orientals), Smokey brown (Periplaneta fuliginosa), and brownbanded (Supella longipalpis) varieties [3]. We were defined 2,25mg/ml protein amounts (w/v) in extracts of the purified and lyophilized protein of the сockroach. We were used a standard marker 195,7; 104,0; 59,8; 41,6; 27,8; 21,1; 15,2; 6,5kd molecular weight proteins on the 13% separation gel of SDS-PAGE. On column determined protein bands with 82,3; 59,9; 55,2; 44,0; 41,6; 34,4, 22,7, 17,1 kd molecular weights.Conclusions: The сockroach was included 8 allergenic protein components between ranges of 17,1-82,3 kd molecular weights were determined in the extracts of the body Blatella germanica.

BACKGROUND: Bladder cancer is a cancer of significant morbidity and mortality in the worldwide. It is the second most common urological cancer in Mongolia. It is important to understand the risk factors of bladder cancer.We evaluated the association of smoking, alcohol intake, body mass index and other potential risk factors with bladder cancer incidence in Mongolians.MATERIALS AND METHODS: We analyzed data from a case-control study (116 histologically confirmed bladder cancer cases and 300 cancer-free healthy, age, gender-matched controls). All participants signed the consent form andfilled out the structured questionnaire including cigarette smoking, BMI, chronic urinary disease andalcohol drinking etc. Using logistic regression we estimated the covariate-adjusted odds ratio (OR) and95% confidence interval (CI) of the associations.RESULTS: Mean age of the patients with bladder cancer was 56±10.5 years and 79.3% male and 20.7% female.Cigarette smoking, history of urinary tract diseases and body mass index were associated with an increased risk of bladder cancer OR 6, 48 (95% CI 1, 61-1, 70), OR 80 (95% CI 1, 48-1, 93) and OR=9.8 (95% CI 2.32-2.91) respectively but not alcohol drinking OR 0, 26 (95% CI 1, 56-1, 66).CONCLUSIONS: The results suggest that cigarette smoking, history of urinary tract diseases and body mass indexincreased risk of bladder cancer in Mongolian patients.

Introduction: Extracorporeal shockwave lithotripsy (ESWL) revolutionizedthe treatment of urolithiasis and graduallybecame the favorite treatment option sothat today it is considered to be the first lineof treatment for patients with urolithiasis.The purpose of this study was assessment oftherapeutic efficacy, complications of ESWLin urolithiasis in Mongolia.Material and methods: A total of46 patients harboring renal and ureteralstones underwent ESWL between March2016 and September 2016 at First CentralHospital of Mongolia. Karl Storz ModulithSLK electromagnetic machines were usedto impart shock waves. All collected stonefragments sent for biochemical analysis.Results: A total of 46 patients 23 weremales (50%). Patients were mean age of34. The stone size distribution was 0.5cmto 3.1cm. The average treatment time wasranging from 75-110 minutes. The averagenumber of shock waves per treatmentwas 3172±378 (range 1500-4000). Theoverall success rate was 75.73%. All calculidisintegrated satisfactorily except for 3stones, which is located lower 1/3rd ofureter. Stone composition analysis proved tobe composed entirely or predominantly ofcalcium oxalate monohydrate. These patientsrequired to have ureterolithoextraction. Calculicomposition for remaining patients 12 werecalcium oxalate monohydrate, 17 calciumoxalate dehydrate, 6 uric acid and 1 struvite.Complications were mostly minor and rare.Most of the patients (90.7%) developedmacroscopic hematuria after treatment; fewpatients developed mild bruising at the entryand exit sites of the shockwaves on the bodywall. Severe complications such as renalhematoma and steinstrasse were diagnosedfor one patient each and their managementwas non-surgical.Conclusion: ESWL is therefore the firstline treatment for urolithiasis with stonesize smaller than 2cm. It has an efficiencyrate above 75, low procedure time, highsafety and good tolerability and minimalcomplication.

Background:
Studies from other countries have identified multiple contributing factors to renal cell carcinoma (RCC).
We conducted this study to investigate the relationship between RCC and certain risk factors among the Mongolian pop
ulation.
Aim:
To identify the risk factors for renal cell carcinoma in Mongolian individuals.
Material and Methods:
This case-control study included 88 patients diagnosed with RCC (confirmed by pathological
examination) in the case group. The control group consisted of 88 healthy individuals matched by age and gender. A
case-control study design was used. Binary logistic regression analysis was conducted on the questionnaire results from
both groups to identify risk factors for RCC through both univariate and multivariate regression analysis.
Results:
A total of 176 participants were included in the study-88 with RCC and 88 without cancer. Statistically signif
icant associations with RCC were found for hypertension, urinary tract diseases, alcohol consumption, and smoking.
Although weight gain appeared to increase the risk for RCC, this was not statistically significant.
Conclusion
Individuals with hypertension, a history of urinary tract diseases, smokers, and alcohol users are at a higher
risk of developing renal cell carcinoma.

Background:
Among the total healthcare waste generated from health-related activities, 10–20% is considered haz
ardous, posing significant threats to both the environment and human health. Approximately 3% of healthcare waste is
pharmaceutical waste. In Ulaanbaatar city, an estimated 2.65 tons of healthcare waste is generated daily (0.78 tons of
medical waste and 1.87 tons of general waste). With the continuous increase in pharmaceutical consumption, the improper
disposal of pharmaceutical waste has emerged as a major environmental concern, adversely affecting nature, animals, and
the food chain. Contamination from pharmaceutical waste, such as the development of antibiotic resistance, is closely
linked to inadequate public awareness of waste management.
Aim:
This study aimed to assess the knowledge, skills, and attitudes of pharmacy technicians in community pharmacies
regarding pharmaceutical waste management.
Materials and Methods:
A cross-sectional survey was conducted among pharmacy technicians across Mongolia. As of
2023, there are 4,959 licensed pharmacy professionals in the country. Using a representative sampling method, data were
collected from 360 pharmacist and pharmacy technicians. Data were analyzed using MS Excel and SPSS version 26.
Results:
A total of 360 pharmacists from both urban and rural areas participated in the study. The assessment was based
on a 5-point Likert scale, with scores of 1-2 considered negative and 3–5 considered positive. The average scores for
knowledge, skills, and attitudes were 3.3, 3.06, and 3.25 respectively. While individual scores were satisfactory, the re
sults of questions targeting social awareness were relatively low.
Conclusion
The knowledge, skills, and attitudes of pharmacy technicians regarding pharmaceutical waste management
were found to be satisfactory. However, to further improve knowledge levels, it is recommended to implement additional
training programs related to pharmaceutical waste management among pharmacy technicians.
