BACKGROUND OF STUDY: According to WHO report estimation, 76.3 million people have been diagnosed with disorder related to alcohol use which has been root cause for over 60 types of disease in the world.1 Smoking causes death to4 million people every year, 11 people every day and 6 every minute. This number is estimated to double reaching 10 million by 2030.2 The study conducted by the ‘World Vision Mongolia’ international organization and the Anti-alcoholism and Drug Association of the Ministry of Justice show 76% of all teenagers has drunk alcohol to some extent. AIMS: To determine alcohol, tobacco and psychoactive drug use by school teenagers of Sukhbaatar district in Ulaanbaatar MATERIAL AND METHODOLOGY: The survey on inquiry of alcohol, tobacco and psychoactive drug use (ASSIST) was conducted among a total of randomly selected 800 (374 boys, 426 girls) students of 8-12th grade from 7 secondary schools of Sukhbaatar district. Statistical data was put into Microsoft office applications (excel, word) and processed by SPSS application with 95% of probability of information and 5.0% of trust level. RESULT OF STUDY: Out of all respondents 32% (256) use tobacco, 43.8% (350)alcoholic drinks, 2.6% (21)cannabis,1.1% (9) cocaine, 1.5% (12) amphetamine, 3%(24)volatile substance, 4.3% (34)sedative and tranquilizer drug, 0.6% (5)hallucinogenic drug, 0.5% (4) opioid, and 0.1% (1) uses other types of drug. Among the survey participants, there are a total of 214 teenagers (in duplicated number) who need short-term action and 2 teenagers who are smoker and need intensive treatment. CONCLUSION: Among total teenagers, the survey participants, 1 in 3 used tobacco, 1 in 2 alcoholic drinks and 1 in 7 used psychoactive drug. Male students smoke twice more than female students and there is no difference in use of alcoholic drink in both sexes. The alcohol and tobacco use among teenagers at the age of 12-18 who participated in the survey showed that they use more when they grow older. 1 in 4 students of all participants belongs to a group with average risk and needs intensive treatment.

Background: Social development due to fat, fast food, obesity and physical exercise depended on chronic cholecystitis and gallstones, still getting younger in recent years. Yaman Serdeg-3 is used in Mongolian Traditional Medicine for the liver and gallbladder and has been studied to support the excretion of bile. We have created a compound recipe, Yaman Serdeg-3 of Mongolia Traditional medicine, added Saussurea amara (L)DC herbal. Saussurea amara (L). DC is high in biologically active compounds, and pharmacology has investigated the bile-expelling action and the effects of the plant on cell growth. Chronic cholecystitis is a common chronic disease of the biliary tract in clinical patients. Symptoms can be seen in right upper abdominal cramps; some patients can be accompanied by abdominal muscle rigidity, the primary disease. It is caused by a large amount of bile blocking the patient’s gallbladder after the stone blocks the gallbladder duct. In the sac, induced acute cholecystitis was again caused by pathogenic factors to form the disease. Aim: Elucidating the effects of supplemental Yaman serdeg-3 in a gallbladder injury model. Materials and Methods: We received permission for animal experimentation from The Ethics Committee of Mongolia National University of Medical Sciences on the 10th of June 2022. The group created a model gallbladder disease with 0.5% a-naphthyl isothiocyanate [C11H7N5] dose (60 ml/kg), treatment with compound recipe Yaman Serdeg-3 (NYS-3) high dose (2.025 g/ml), medium dose (1.35g/ml), low dose (0.675g/ml), that used to compare URSO 250 (0.0042g/ml) for 21 days. The third group created a model liver disease with a 40% Carbon tetrachloride [CCl4] dose (4 ml/kg), treatment with compound recipe NYS-3 high dose (2.025 g/ml) and that was used to compare Hu gan pian (0.046g/ml) of China medicine for 21 days. Liver tissue pathological sections were collected quickly after blood collection in rats. The liver, stomach, and duodenum tissue on the right page were immersed in 10% neutral formalin and fixed for pathology. Histological examination: The fixed tissue was trimmed, dehydrated, embedded, and cut. After slides, HE staining, sealing, and other procedures, an optical microscope was used to observe. Results: In our study, the structure of the liver tissue cells in the high-dose group of Yaman serdeg-3 was preserved, the vessels had irregular blood vessels, and there was significant infiltration of chronic inflammation in the triple bypass. In this group, we divided the Yaman serged-3 into three groups: low-dose, medium-dose, and high-dose. In the model group with liver tissue analysis, the low-dose and medium-dose groups had fewer chronic inflammatory cells in triads and interstitial cells. In contrast, the fact that the high-dose group of Yaman serdeg-3 showed sparse trigeminal and interstitial and very few chronic inflammatory cells indicates that our study met its objectives, and the tissue analysis showed that the high-dose group was more effective. Conclusion During the acute and toxic liver disease model in rats, the inflammation process in the liver cells was high, and watery changes and fatty changes damaged the liver tissue. It has been confirmed that traditional herbal medicine, Yaman serdeg-3, reduced protein and fatty tissue changes in the hepatocyte membrane and accelerated liver and biliary tract regeneration. Furthermore, our study has shown that Yaman serdeg-3 may have stimulated bile secretion dose-dependently and accelerated hepatocyte regeneration. Also, liver tissue analysis of the control group showed significant inflammation in the triad and interstitial cells; blood vessels were filled with blood, and cell structure was preserved. In contrast, the comparison drug group had significant triad inflammation and fewer inflammatory cells in the interstitial cells.
