Abstract:
The lactate dehydrogenase (LDH) enzyme is widely distributed in tissue, particularly heart, liver muscle, and kidney. The LDH in serum can be separated into five different isoenzymes based on their electrophoretic mobility. Each isoenzyme is a tetramer composed of two different subunits. These two subunits have been designated heart and muscle, based on their polypeptide chains. There are two homotetramers, LDH-1 and LDH-5, and three hybrid isoenzymes.
Elevated serum levels of LDH have been observed in a variety of disease states. The highest levels are seen in patients with megaloblastic anemia, disseminated carcinoma, and shock. Moderate increases occur in muscular disorders, nephrotic syndrome, and cirrhosis. Mild increases in LDH activity have been reported in cases of myocardial or pulmonary infarction, leukemia, hemolytic anemia, and hepatitis.
This study aims to compare a LDH activity in comparatively healthy Mongolian population using highly sensitivity modern technology and evaluate their contents with age, sex, and work adults differences, For this purpose there were chosen 3742 healthy adults (1597 males and 2145 females). The enzyme activity were investigated in Mobio laboratory using fully automated analyzer COBAS Integra-400. Study results were assessed using Microsoft Excel SPSS-10 standard program and evaluation.
The study results show that mathematical mean of LDH activity of healthy Mongolian population is 322.6 u/l, quadratic mean of deviation is 44.9 u/l, and significant distribution is 187.2-442.6 u/l with p=0,99. The mathematical mean of LDH activity of healthy Mongolian man 187-444 u/l, but for women it is 187-438 u/l, with haven’t differences. The level LDH activity of healthy Mongolian population does not depend from age. The level LDH activity of healthy Mongolian population have differences from work adults.
Conclusion:
1.From the findings indicated LDH activity by 187.2-442.6 u/l.
2.Study findings shown LDH activity level not influenced for age and sex.
3.There fore we defined LDG activity level influenced physical and mental overload.

Background :
Low triglycerides and cholesterol was associated with hepatitis C virus (HCV) infection. Chronic HCV infection is the main cause of liver injury and it may influence to serum lipid levels. We aimed to evaluate the effect of antiviral treatment on the change of lipid profiles during interferon-based anti-HCV treatment.
Material and Methods :
Totally 863 patients who completed the interferon-based antiviral therapy in Kaohsiung Medical University Hospital were included in this present study. The lipid profile measured and assessed in the baseline of the treatment and after 6 months of completion of the treatment.
Results :
The most of the patients (81.2%) were achieved sustained virological response (SVR) by antiviral therapy. There was no significant difference between baseline triglycerides (TG) levels in the SVR group and non SVR groups. The TG levels at 6 months after completion of the treatment was significantly elevated in SVR group (102.9±57.0 mg/dL, p=0.0001) but did not elevated in non SVR group (94.5±45.6 mg/dL, p=0.690) compared with baseline TG levels.
After adjusting patients by four indexes for fibrosis (FIB4) in cut-off point 3.25, serum TG levels significantly increased in low FIB4 group (103.2±57.9 mg/dL, p=0.0001) but not in high FIB4 group (98.1±49.6 mg/dL, p=0.095) after 6 months end of the treatment. Serum TG level was increased greater in patients who had low FIB4 score and patients who achieved SVR (baseline 89.1±34.8 mg/dL; 6 months after treatment 104.3±59.3 mg/dL, paired T test p=0.0001).
Conclusion
The eradication of HCV is the main cause of the increase of lipids after Pegylated Interferon and Ribavirin treatment.
However advanced fibrosis also has an effect in increase of TG after the treatment.

Abstract:
Burn injury causes considerable incidence of disability, increase of hospitalization and rehabilitation. It is a crucial factor of morbidity and mortality, throughout the world, especially in the developing countries. Burn wound healing is a complex process including inflammation, granulation, and regeneration of the skin tissue. There are many animal and mineral derived agents applied for burn wounds treatment. For example, minerals and animal yellow marrow are applied as standard topical therapy in healing of burn wounds in the history. Specially, Mongolian camel’s (Camelus Bactrianus) yellow marrow and cinders have been used the healing effect standard topical antimicrobial for burn wounds for several centuries. The present study aimed to determine the healing effect of “CIBO” ointment with animal and mineral raw materials on third -degree burn wound in rats.
Introduction:
In our study, we selected an ointment containing a combination of yellow marrow and cinder. In ancient times, Mongolians used camel yellow marrow to relieve joint pain, spread people who had been bedridden for a long time due to the disease, and to prevent caries, and to use it on open wounds. In traditional medicine, cinder has been used as a mineral raw material and has been used to treat frostbite and burns.
Material and methods:
In the Vivar Department of the Pharmacology Sector of the Drug research institute, 18 Wistar white rats weighing 182-220 g fed in one environment for (12 hours a day/12 hour a night) were randomly selected and divided into the following groups. These are: negative control, Group 1 “Yellow marrow + Uvs black cinder”, Group 2 “Yellow marrow + Uvs brown red cinder”, Group 3 “Yellow marrow + Chinese red cinder”, Group 4 “Yellow marrow + Chinese white cinder”, Standard “Mebo” wound ointment. The wound area was prepared by scraping the hair 5 cm from the back of the test animal’s skull. The prepared area was sterilized with 70% ethanol and 10% iodine solution, resulting in a third-degree burn wound of 2.4 cm2. Wound experiential’s ointments were applied once daily for a total of 28 days, and wound healing was evaluated at 0, 3, 7, 14, 21, and 28 days after pathogenesis, with 16.1-pixel accuracy. Photo confirmed using a SONY brand camera.
Result:
“CIBO” ointment contains four deferent cinders which are from collected from deferent area and that have been shown to good affect burn wounds, and is more compatible with yellow marrow than Group 4 (Yellow marrow+Chinese white cinder).
Wound healing variables of control group compared with group 4 (Yellow marrow + Chinese white cinder) increased by 11.1% on the 3th day, 4% on the 7th day, 44.8% on the 14th day, and 54.5% on the 21st day. On the 28th day, healing and regeneration were accelerated by 50%.
Conclusion
The group 4 (Yellow marrow + Chinese white cinder) has been shown to have a pharmacological action of rapid healing and regeneration of burn wounds caused by experimental rats. It has also been shown to have pharmacological action to regenerate skin tissue and suppress inflammation caused by burns. Inclusion of Chinese white cinder in “CIBO” ointment promotes regeneration and healing of “CIBO” ointment.

Introduction:
In Mongolia, there is opportunity to replace importing products by using raw materials based on the animal and minerals. Those products can be used for medical purposes.
In traditional medicine, yellow marrow has been widely used to treat burns and mechanical wounds, as well as frozen and open wounds. The purpose of this study was to determine the pharmacological action of “CIBO” ointment. We created a model of mechanical wound to evaluate the healing of wounds and its index after applying the ointment contains the above mentioned raw materials.
Material and methods:
Four different groups of “CIBO” ointment was prepared in the technology sector of the Drug Research Institute. Mebo wound ointment was used for comparison as control. The study was con- ducted in the Pharmacology Sector of the Drug Research Institute on white rats of the WISTAR breed under one feeding regime and one condition (12h / 12h). Mechanical wound injury and exposure to open wounds in experimental rats and its size were measured on the 3rd, 7th, 14th, 21st, and 28th days of treatment. Wound healing, morphology, structure, size, and its index was quan- tified based on the defects. The ointment were applied once a day during the treatment period of 28 days to cover the wound.
Result:
Mechanical wound showed that study treatment group healed 0-6.2% on the 3rd day, 21.4-35.7% on the 7th day, 50-60% on the 14th day, and 33.3-50% on the 21st day separately compared with the untreated group. On the 28th day, all the groups were decreased by 66.6%. The wound index was between from 0.002 to 0.0005 in the all experimental groups. Among experimented groups, the group consists of yellow marrow and Chinese white cinder was showed better performance than other groups.
Conclusion
The study group 4 (Yellow marrow + Chinese white cinder) has been showed to have a pharmacological action of rapid healing and regeneration of burn wounds caused by experimental rats. It has also been shown to have pharmacological action to regenerate skin tissue and suppress caused by mechanicals. Inclusion of Chinese white cinder in “CIBO” ointment promotes regener ation and healing of “CIBO” ointment.

Introduction:
In 2018, a total of 901 new cases of gastric cancer were recorded, of which 64.8% in males and
34.2% in females. The incidence rate of gastric cancer was 28.5 per 100 000 population, which 38.2
for males and 19.2 for females.
Goal:
We aimed to investigate the associations between some risk factors and gastric cancer among the
Mongolian population.
Materials and Methods:
A case-control study was conducted between November 2017 and September 2019. We selected
120 cases from National cancer center of Mongolia who newly diagnosed gastric cancer. And 120
controls were selected by matching by sex, age and the place of residence. Informed consents
were obtained from all subjects. All subjects were personally interviewed with researchers used by a
structured questionnaire consisting of 86 questions. The SPSS 21 (version 16.0, SPSS Inc., Chicago,
IL, USA) software was used for all analyses.
Results:
The mean age was 59.2±11.4 (26-85) years. Habits of having dinner after 6.00 pm (OR 1.42, 95%CI
1.11-1.83, p=0.008), having leftover meals (OR 2.22, 95%CI 1.27-3.86, p=0.008), daily consumption
of tea with salt (OR 1.97, 95%CI 1.18-3.30, p=0.01), smoking on an empty stomach (OR 2.44,
95%CI 1.11-5.37, p=0.033), weekly consumption of ham and smoked meat (OR 1.5, 95%CI 1.17-
2.13, p=0.02), and consumption of fat grease (OR 2.09, 95%CI .03-4.24, p=0.038) were significantly
increased gastric cancer risk. In contrast, habit of eating at regular times (OR 0.43, 95%CI 0.25-0.73,
p=0.002), chewing thoroughly (OR 0.39, 95%CI 0.23-0.67, p=0.001), cooking meat thoroughly until
it’s tender (OR 0.48, 95%CI 0.25-0.97, p=0.047), daily consumption of vegetables (OR 0.45, 95%CI
0.27-0.76, p=0.003), and daily consumption of fruit juice (OR 0.36, 95%CI 0.15-0.85, p=0.026) were
significantly reduced gastric cancer risk. Furthermore, having first-degree relatives diagnosed with
gastric cancer had 2-3 fold higher increased risk of gastric cancer (parents OR 2.88, 95%CI 1.07-
7.78, p=0.038, sibling (OR 3.09, 95%CI 1.09-8.81, p=0.036). Also, previous records of the digestive
disease increased risk of gastric cancer (OR 3.65, 95%CI 2.10-6.35, p<0.0001).
Conclusion
Dietary habits, family history of gastric cancer and previous records of digestive disease were
associated with risk of gastric cancer. Thus, prevention effort could be focused on the population with
a family history of gastric cancer, changing bad dietary habit and screening precancerous disease of
gastric cancer.
