We present the fi rst 2 cases of cochlear implantation in Mongolia using “SONATA” type implant of “MED-EL” Company, Austria.
CASE 1: A six years old, female had been diagnosed with bilateral congenital profound hearing loss and had been fi tted with hearing aids for 5 years and received little benefi t from her hearing aids and developed very poor speech and language, used lip reading and have had vocabulary of approximately 10 words. A radiological evaluation showed normal cochlea and auditory nerve. Cochlear implant team including speech therapists and audiologists based on the informed consent of patient’s parent decided that family able to participate in follow-up, speech habilitation programme.
Patient implanted with SONATA of MED-EL on 4 August, 2009. Electrodes were inserted fully.
After 10 days of switch on of the speech processor the patient showed signs of initial hearing of loud sounds. After 5 months of Auditory Verbal Therapy the vocabulary increased up to 50 words. Hearing, cognition and responses are increasing simultaneously.
CASE 2: A 2 years old female. Congenitally deaf in both ears. Fitted with hearing aid for 3 months before the surgery and there was no benefi t from hearing aid. Physically and mentally healthy. Patient implanted with SONATA of MED-EL on 4 August, 2009. Electrodes were inserted fully. On 25th days of switching on of speech processor the patient showed initial hearing of loud sounds. Currently, after 5months of treatment her vocabulary is 2 short words and can recognize 4 syllabeles. She is very active, repeats actions and has open nature, feels comfortable with CI.

Background. A large number of longitudinal studies indicate significantly increased risk of cardiovascular
events and death in people with the MetSyn and high plasma levels of triglycerides are an independent
risk factor for the development of cardiovascular disease. Apolipoprotein A5 (APOA5) gene, a new
member of the APOA1/C3/A4 gene cluster, was identified by comparative sequencing of human and
mice DNA by Pennacchio and co-workers in 2001. Since this discovery, variants of ApoA5 gene have
been independently assiociated with level of plasma triglyceride in many countries. Human ApoA5 is
expressed in the liver then appears in plasma in association with VLDL and HDL and plays a major role
in TG catabolism. Variant at ApoA5 gene locus, 1177C>T is located in 3’ UTR which often contains
regulatory regions that influence post-transcriptional gene expression. One alteration can be responsible
for the altered expression of many genes.
Materials and Methods. 152 people with MS for case group and 152 people for control group were selected
in this study. MS was diagnosed according to IDF criteria and serum triglyceride levels were determined.
DNA from both case and control subjects were extracted from blood samples (200 ml) using “G-spin™ Total
DNA Extraction Kit”(iNtRON Biotechnology, Inc). To detect the 1177C>T variation of ApoA5 gene, using
High Pure PCR Template Preparation Kits, a forward primer 5’-CTCTGAGCCTCTAGCATGGTTGAGT-
3’ and the mismatch reverse primer 5’-GAGCATTCCCAAATGAGCAC-3’ were used to create the HinfI
restriction site.
Results. There were 304 total subjects included males 50.3% (153) and female 49.7% (151) in our
study. Incident of CC genotype was 71.1% (216), CT genotype was 25% (76) and TT genotype was
3.9%, TAG level was higher in males than females in both groups (p=0.016, ð=0.001) for CC genotype
and also, higher with MS in males for CT genotype (p=). But, TAG level was no significant difference
among three genotypes in group with MS subjects (male p=0.236, female p=0.881).
Conclusion: The TT genotype of the ApoA5 gene 1177C>T polymorphism frequency was 2.9% in control
subjects and 4.9% in subjects with MS. However, TG level was not differ in both groups for TT genotype,
TAG level in males was higher compared with females (p=0.016 in control, p=0.001 in group with MS).

:
In enterohepatic recycling, foreign chemicals entering the alimentary tract and gut normal micro flora (<b>ShagjJambal., 1989b>) are absorbed into portal venous blood by enterocytes, removed from blood by uptake into hepatocytes, secreted into the bile, and then deposited back into the intestinal lumen where they may be reabsorbed by intestinal wall cells and available for recycling (compartment model modified by <b>Wang and Reuningb>). This process is called enterohepatic circulation or enterohepatic recycling (<b>Rollins and Klaasen, 1979b>). Some studies have attempted to interrupt the enterohepatic recycling of toxicants such as pesticides and heavy metals and 56 carbon tetrachloride (<b>CCl4b>). Plant Material The plant Gentiana macrophylla pall. Was collected during july 2017 from the forest region Galt sum, Khuvsgul aimakh, Mongolian. The taxonomical identification of the plant was done by Botanical survey of Ganbold E. (ScD) Mongolian university subsidiary of Ulanbator institute, Ulanbator. The study was based on the New medicine medical university bio-model, pharmacology laboratory and laboratory. ELISA-biochemistry laboratory.
Animals:
Male C57BL/6 (miceweight 18-22g (n=40)) were obtained from the Mongolian national university of Medical sciences animal house. Experimental procuders were conducted in accordance with the regulations of Animal Ethical committee. Myeloperoxidase (<b>MPOb>) activity was measured according to the technique described by <b>Krawisz et al. (1984) b>. Assay for lipid peroxides in animal tissues by thiobarbituric acid Reaction (<b>Yagi, K. and Ohkova.,1979b>). A significant decrease (P<0.005) in the MDA was observed in the <b>Gentiana macrophyllab>(GM) treated group (0.340±0.031)when compared with the control group (0.521±0.023).
Conclusion
The results of the study show that Gentiana macrophylla is inhibition of lipid peroxidation, protection of liver cell. From the protonation compounds generate polyphenol compound with rich hydroxyl and alkaloid. These compounds help to lipid peroxidation or antioxidation and membrane protection.The results of the study show that Gentiana macrophylla is inhibition off oxidation ferric molecule in vitro reaction and detoxification of reactive oxygen species release from damaged liver cell by CCL4.

Background:
Poor laboratory quality can lead to misdiagnosis and inappropriate treatment of patients. To demonstrate the quality and reliability of their services, medical laboratories seek accreditation to ISO 15189. We have initiated a project to assist laboratories in their efforts to obtain the accreditation.
Goal:
Conduct a gap analysis of the status of preparedness of medical laboratories for accreditation.
Materials and Methods:
Six laboratories are selected for participation in the project. In the first phase of the project, a gap analysis of the participant laboratories is conducted using an Excel program based on ISO 15189 requirements.
Results:
The findings reveal that the participant laboratories are the strongest in Organization and management of laboratory, Quality of examination results, Personnel and facility management and in Laboratory information management. The majority of the laboratories are hospital based, and their organization and
management are well established and functional mostly due to centralized administrative guidance. The concept of quality control is effectively adapted in medical laboratories, therefore ensuring the quality of examinations and the data management are usually in line with the requirements. Weaker areas include
Evaluation and audits, and Document control. Even though the laboratories do conduct evaluations and control, they do not do it regularly and, most importantly, do not keep records routinely, which cause the higher gap rate.
Conclusion
Policies to meet ISO 15189 requirements are in place in the participant laboratories, but their documentation and records keeping are insufficient.
