The result of endovascular surgical treatment of congenital heart disease Background: Over the last 10 years the advances in catheter based interventions for congenital heart disease(CHD) include new procedures, devices and almost 25% of all CHD are now can be treated by endovascular surgery. The purpose of this report was to evaluate the outcome and result of endovascular surgeries for congenital heart disease. Materials and methods: The study included all cases of endovascular surgeries at the National Center for Maternal and Child Health the period of 2014-2019. Results: Total 631 cases had intervention procedures and 377 (59.7%) cases had endovascular surgeries for CHD. 268 patients had patent ductus arteriosus device closure successfully while 57 had pulmonary artery valvuloplasty using balloons. Also 76 patients had device closure of atrial septal defect and 4 patients had device closure of ventricular septal defect using new multifunctional occluder. Another 20 patients had severe coarctation of aorta and had balloon dilatation and stenting as a life saving procedure. Conclusions: Endovascular surgery for CHD is a safe and effective alternative to open heart surgery.

Background: Plants have played a significant role in maintaining human health and improving the quality of human life for thousands of years and have served humans as valuable components of seasonings, beverages, cosmetics, dyes and medicines. There are a number of medicinal plants used in the traditional medicine in the Mongolia to form “tan” prescriptions which are mostly consist of the mixture of individual medicinal plants and used by nomads during the long history for their health care as medicines. Lancea tibetica (Scrophulariaceae) is a traditional herbal medicinal plant in Mongolia, China and Tibetan. In Mongolian traditional medicine, L.tibetica different exclusive forms of preparations are effective for treatment of some disorders such as pulmonary, cough and heart disease. Aim: This study aim was to define the biochemical some composition antibacterial activity and mineral elements content in air-dried samples Lancea tibetica of Mongolia. Material and Method: The antibacterial activity and Minimal Inhibitory Concentration (MIC) of the extracts was collected of the seed, aboveground part and root for the Lancea tibetica. From three different organs of plant Lancea tibetica was collected of the Tsenkher district Arkhangai province (2017.07.28) and Tunel district Khuvsgul province (2018.08.27) were evaluated by means of the Disk diffusion method against five bacteria (Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Micrococcus luteus, Enterococcus faecalis). We have taken extracts of plant 3 organs from organic solvent (7) ethyl acetate, hexane, n-butanol, methanol, chloroform, ethanol and distilled water for antibacterial activity. MIC of the extracts were defined and compared with each other. The macro-and microelements were determined by X-ray fluorescence spectrophotometer analysis (XRFA). Result: We have taken a dried seed, aboveground part and root of Lancea tibetica in the investigation. In these three samples were determined biochemical composition of 11 components for quantitative analysis: moisture was 6.2±0.2%, ash 4.8%, protein content was 1.67±0.1%, raw oil 5.9±0.3%, reduction sugar 0.39±0.1%, vitamin Р 16.6±1.8 mg%, extractive substances 18.6±0.2%, tanning matter 0.05±0.02% and flavonoids 0.2±0.01% in seed. The same moisture was 6.7±0.4%, ash 9.7%, protein content 1.89±0.2%, raw oil 6.1±0.8%, reduction sugar 0.52±0.1%, vitamin С 3.52±2.2mg%, vitamin Р (rutin) 20.3±0.2mg%, carotene 12.8mg%, extractive substances 16.8±0.1%, tanning matter 0.08±0.01% and flavonoids 0.6±0.24% in aboveground part. Besides this, in root: the moisture was 6.1±0.3%, ash was 14.9%, protein content was 2.1±0.3%, raw oil was 2.9±0.2%, reduction sugar 0.62±0.02%, vitamin Р 17.8±0.05mg%, extractive substances 20.3±0.4%, tanning matter was 0.06±0.03%, flavonoid was 0.35±0.002%. Besides this, we revealed the saponin by method quality analysis in aerial part and root of Lancea tibetica. But not triterpenoid saponin in seed. The same not revealed alkaloid all the samples.
Eighteen extracts (5mg/disc) of three organs (seed, aerial parts and root) showed antibacterial activity diverse. The MIC in ethanol and butanol extracts of seed, aboveground part and root was more than others.
From thoroughly air-dried aboveground part samples of Lancea tibetica from Tsenkher district of Arkhangai province and Tunel district of Khuvsgul province. We determined the 43 mineral elements. 11 elements were defined by percentage, 10 elements were oxide forms (SiO₂, TiO₂, Al₂O₃, Fe₂O₃, CaO, MgO, Na₂O, K₂O, MnO, P₂O₅) of them. Other elements were defined by mg/kg unit. The same heavy metallic, mobile elements (Cu, Cr, Zn, Mn, Pb, Ni, Co) and rare earth elements (Ce, La, Nd, Pr, Sm) were determined. Conclusion In the result of this research work to determine the content of biologically active substances in Lancea tibetica. Plants produce a great variety of organic compounds that are not directly involved in primary metabolic processes of ground and development. Study of the biochemistry of plant natural products has many practical applications. Various detectable contents of useful or macronutrient and micronutrient oxide was found in the ash of aerial parts. Some macronutrient and micronutrient elements were detected by oxide forms.

Objective: To compare the nature of pregnancy and deliveryin women with leiomyoma who were treated with uterine artery embolization to the outcomes in women who were treated with abdominal myomectomy. Material and Methods: A prospective, clinical study was conducted in 2010-2013 at “Urguu” Maternity Hospital, Ulaanbaatar. 94 women meeting the criteria were selected for the study. Post-treatment, the patients were reviewed for a period of two years. Uterine artery embolization was performed using polyvinyl alcohol particles (300-500 µm in diameter). Results: The percentage of conception in UAE group was 25.5% and 31.9% in myomectomy group (p=0.494); complication of pregnancy was 50.0% and 57.1% respectively (p=0.729); complication of delivery was 33.3% and 0.0% respectively (p=0.047). 88.9% and 90.0% (p=0.596) had Caesarean delivery. 16 (84.2%) women had uncomplicated and 3 (15.8%) women had complicated delivery due to placenta praevia, placenta acreta and uterine hypotonia. These cases all belonged to UAE group. Conclusion Pregnancy rates in women with leiomyoma who were treated by uterine artery embolization, compared with pregnancies after abdominal myomectomy, were similar.(p=0.494) In this study, there was the rate of Cesarean delivery above 80 percent in both group. There were no differences in newborn weights and Apgar scores.

In United States, person is diagnosed with blood cancer in every 3 minutes. In 2015, there were 1.665.540 total cancer cases and 9.4% of them lymphoma and leukemia . In 2015, there were 95 cases of lymphoma in Mongolia when compared 4 times increase to 2015 from 2010 . Bone marrow examination is an established diagnostic modality in the evaluation of various hematological disorders. BM examination can serve to establish or confirm a primary diagnosis of lymphoma or to determine the extent of disease dissemination for staging purposes. Biopsy is essential for diagnosis in a dry tap or blood tap which occurs when the marrow is fibrotic or densely cellular. Only a biopsy allows a complete assessment of marrow architecture and pattern of distribution of any abnormal infiltrates. In 2015.01-2016.01 fifty five bone marrow biopsies were retrieved from the files of the National First Clinical Hospital-Department of Hematology. These all statistical analysis was performed using by SPSS 17. Bone marrow processing and staining: The hematologist is instructed to place the freshly obtained BMTB specimens directly into buffer substance fixative and transport it immediately to the histopathology department, on the same day as the procedure.The next morning (after 20–24 h), the solution is decanted (with a strainer) and the biopsy specimen is washed in distilled water for 30 min. The biopsy specimens are left to decalcify for about 6 h before being processed and embedded in paraffin wax, with procedures similar as for other specimens.Sections, 1-mm thick (microtome set for 1 mm sections), are cut from the paraffin-wax blocks with the routine rotary microtomes in the laboratoryA total of 55 cases were reviewed from December 2014 to November 2015. The age of the subjects ranged from twenty two years to seventy eigth years with a male predominance (1.7:1). Data of 55 trephine biopsies were reviewed. The percentage of trephine biopsies in different length ranges was calculated. Twenty two biopsieswere of recommended length, i.e., ≥1.5 Cm while remaining 33 were less than the recommended length. The rate of positivity for diagnosis was 95.4% in group-1, 94.1% in group-2, 63.6% in group-3 and 40% in group-4 In all cases in our study 73% (n=40) were satisfactory and 27%(n=15) unsatisfactory slides .Our study showed that 40% trephan biopsies were of revommended length i.e >=1.5cm with 95.4% positive of diagnosis. However biopsies measuring 1-1.4 cm also had comparable result 94.1% .

Uterine leiomyomas are common (20-50%) in women of reproductive age. It is a benign tumor and it ranks second place among genital organ disorders in women.To date, abdominal laparotomy and laparoscopic surgical treatment (myomectomy and hysterectomy) are widely used to manage symptomatic leiomyomas.Although, hysterectomy is considered to be a radical method to manage uterine leiomyomas, women who have had hysterectomy are left totally infertile and they also are at risk to develop post-surgical and post-anesthetic complications. The advantage of myomectomy is to preserve women’s fertility and menstrual function but, the probability of recurrence of leiomyoma is 15-30% [1, 2]. Furthermore, depending on the location, size and number of fibroids, duration of surgery lingers, volume of blood loss is high and the risk to develop post surgical adhesions are high too.In recent, more than a decade period, effective and minimally invasive new, non-surgical methods to manage uterine leiomyomas have been introduced in many countries around the world. These methods have short recovery period and are advantageous to women to preserve their reproductive organ and fertility. They include: uterine artery embolization, uterine artery occlusion via transvaginal route and MRI– guided focused ultrasound surgery of uterine fibroids. Antiprogesterone-low-dose mifepristone for uterine leiomyomas are being introduced as well.In our country, managing leiomyomas surgically is still occupying high rate among surgical treatments. Further, to prevent and reduce complications of surgical treatment and to preserve organ, it is essential and imperative to introduce some of the above- mentioned contemporary non-surgical methods.

Most of patients with clinicalsymptoms were high level of biochemical parameters such as AST, ALT, ALP, GGT

INTRODUCTION:Uterine leiomyoma occurs with broad range of 20-50% among reproductive aged women. It takessecond place of all women’s genital diseases that cause abnormal menstrual bleeding. Leiomyomadependent surgical frequency such as hysterectomy is around up to 80, 6%. Lately uterine fibroidembolization treatment is highly effective, less painful, and more rapid recovery, most importantlykeeping organ while maintaining the reproductivity, is successfully entered in practice. We successfullyperformed 40 cases first time in Mongolia and 8 of them conceived naturally after treatment.GOAL:To determine if arterial embolization in women with uterine fibroids (leiomyomata) is an effectivemethod to keep their reproductive organ intact.OBJECTIVES:• To study pregnancy cases in women who had uterine fibroid embolization• To monitor and determine the features of course of pregnancy and childbirth.• To evaluate uterine fibroids.MATERIALS AND METHODS:The study was conducted in 2009-2012. A total of forty women between 23-50 years of age,diagnosed with symptomatic uterine fibroid that received embolization treatment of dominatingarterial blood vessel feeding the uterine fibroids were involved in the study. Eight of the forty womenwho conceived naturally were selected for the study. The study focused on monitoring the course oftheir pregnancy and delivery and its outcome.RESULTS:Among 40 women who underwent bilateral uterine artery embolization, 31 (75.5%) were seeking tobecome pregnant, and 8 of the 31 (25, 8%) became pregnant, four having been nulliparous. Onepatient had two pregnancies. All 8 pregnancies were spontaneous. The mean time from embolizationto conception was 12±3, 5 months (range, 6-27 months). Three medical terminations occurred. Theother 5 pregnancies went to term; one pregnancy had to be terminated pre-term due to placentapraevia. 60% experienced threatened abortion and 1 case with advanced age mother complicatedwith mild preeclampsia. 62,5% of the women’s pregnancy ended with childbirth, of which one woman(20%) had vaginal delivery and the remaining four pregnancies (80%) ended with C-section. On anaverage, post-treated uterine fibroids decreased in volume by 94% in comparison to pre-treateduterine fibroids in the patients who became pregnant. All of the neonates were healthy with Apgarscores greater than8. The mean weight of the neonates was 3,189± 200 g (range, 2,100–3,800 g). One neonate waspreterm due to placenta praevia (2,100 g).CONCLUSION:1. Of the forty women that received arterial embolization treatment with uterine fibroid, thirty one(75, 5%) women desired to keep their uterine for further reproduction, of which eight women (25,8% of the patients) between the ages of 23-42 years (mean age=35) conceived naturally. Arterialembolization to treat women with uterine fibroids is an effective method for women who wish to keeptheir reproductive organ intact to conceive and reproduce.2. 60 percent of the women who conceived experienced threatened abortion and 20 percent of thewomen’s pregnancy had to be terminated pre-term due to placenta praevia. 62,5 percent of thewomen’s pregnancy ended with childbirth, of which one woman (20%) had vaginal delivery and theremaining four pregnancies (80%) ended with C-section.3. On an average, post-treated uterine fibroids decreased in volume by 94% in comparison to pretreateduterine fibroids.

The aim of study was to evaluate the antioxidant action of the medicinal herb ZygophyllumPotaninii Maxim on rat liver hepatitis induced by carbone tetrachloride (CCl4), and the content of selenium in this herb. The results showed that the content of selenium in the surface part of ZygophyllumPotaninii Maxim was 0.34 ppm, while in the infusion it was 0.14µg/ml and 0.12µg/mlin the extract. ZygophyllumPotaninii Maxim water extract at the dose of 200mg/kg. CCl4 was diluted with heliante oil (1 /4 v/v) for experimental groups and these treatments were administrated three times in a week for a period of 12 weeks. Therefore, the aim of the present study is to investigate the possible protective role of selenium on the experimental liver cirrhosis and some enzyme activities in blood plasma from rats. Based upon these results, selenium may play in important role in the preventive indication of hepatic cellular injury inducted by carbon tetrachloride.

Introduction. Cancer of unknown primary (CUP) is histologically defined as the presence of a metastasis of lymph node without detection of the primary tumor [1]. Approximately 3–15% of all cancers are designated as CUP [3. 4]. The diagnosis, treatment and monitoring of patients with laterocervical metastases of unknown primary involves a wide range of oncologic entities [5]. While we were studying patho-histological examination of cervical lymphadenopathy in Mongolian, werevealed unknown primary tumor. This is a goal of our study. Objectives of study are followings to differentiate whether primary lymphoma or metastatic cancer of cervical lymph node metastasis of unknown primary tumor and to reveal primitive origin of tumor using by basic and additional immunohistochemical markers.Goal.To determine the conclusive diagnosis in cervical lymph node metastasis of unknown primary origin by immunohistochemical techniqueMaterials and Methods. In this study, we examined immunohistochemically 30 cases of outpatient head and neck surgical unit of the National Cancer Center and dentistry and oral maxillofacial surgical unit of the State Central Hospital which were diagnosed as cervical lymphadenopathy. For immunohistochemical study, we applied an immunohistochemical panel in accordance with avidinbiotin- peroxidase complex method and used a basic and additional antibodies represented by CK(pancytokeratin), LCA, synaptophysin, chromogranin and HMB45. Result. In our study, there was 63.3% lymphoma, 36.7% metastatic cancer. Among them, there were 4 of digestive tract adenocarcinoma, 3 of squamous cell carcinoma /2-esophagus, 1-nasopharyngeal/, 2 of neuroendocrine tumor and 1 of melanoma.Distribution by age groups shows that 20-29 years were 4(13.3%), 30-39 years were 10 (33.3%), 40-49 years were 8 (26.7%), 50-59 years were 3 (10%), over60 years were 5 (16.7%). Gender distribution showed an increased incidence of males (56.7%, 17 cases) compared with females (43.3%, 13 cases).Conclusion: In our study, B cell lymphoma and digestive tract adenocarcinoma were the most common. In further, it is necessary to introduce an immunohistochemical method in patho-histological practice.
