IntroductionThe main principles of pharmacotherapy are to provide pharmaceutical care with right medicine, right doses, in right time. If, the treatment plan can be in evidence based, it will improve treatment efficacy and safety, can prevent from drug related adverse event and reduce drug cost. Ischemic heart disease is one of major cause of mortality and one of the main diseases of morbidity in Mongolia and in the Worldwide.GoalAim of study was to conduct retrospective study on medications used for in-patients with Ischemic heart disease of tertiary level hospitals of Ulaanbaatar.Materials and MethodTotal of 438 patient’s records was collected randomly from 3 state hospitals, which were treated with diagnosis of ICD. Variables of study were patient’s diagnosis, age, sex, names, doses and route of medications.ResultThe trends of rational use of drug and number of drug and drug cost per patients were different in each tertiary level hospitals of Ulaanbaatar. In I national hospital, number and cost of drug per patients were higher than second and third state hospitals. The result were shown that in all three hospitals, more than 50 percent of total drugs per patients were injection, less than 50 percent of total used drug per patients were from standard therapeutic guideline. In second state hospital, anticoagulant and anti-platelet agents were chosen less than first and third state hospitals. In order to decrease cardiac oxygen demand and improve cardiac microcirculation, nitrates were chosen mostly in second and third state hospitals but, beta blockers were chosen mostly in first state hospital.ConclusionThe study results shown the treatment pattern and trends of rational use of drugs in in patients with ischemic heart disease have been different in tertiary level hospitals of Ulaanbaatar.

Background: Development and progression of cancer is accompanied by different morphological and functional changes of cells. One of the most important changes is the expression and activity of enzymes in the cellular fatty acids metabolism that reflects in cell membrane lipid composition and increases fluidity of cancer cell membrane. The Ellipin, prepared from bovine liver, is a newly developed anticancer agent containing several important fatty acids.Goal: To investigate effects of Ellipin on hepatic cancer cell function such as proliferation, migration and adherent activity and apoptosis of cancer cell lines in vitro.Materials and Methods: This study was conducted in the Laboratory of Molecular Biology, Institute of Biology, MAS. The Ellipin was developed in the Drug Research Institute of Monos group. HepG2, HCC, 23132/87, MDCK cells lines and the primary liver cancer cells (PCC) were used for proliferation assay. Only HepG2 cell line was used for MTT, Migration, Spreading and Apoptosis assays.Results: The results of proliferation assay showed that the ellipin decreased the proliferation activity of HepG2 and PCC cells depending on concentrations; in 50μg/ml 2-3 times, 250μg/ml fully stopped cells divisions. The Ellipin reduced mitochondrial reeducates enzyme activity of HepG2 cells depending on its concentrations. For example, in 50μg/ml ellipin concentration case, the number of alive cells decreased 2 times. The migration of HepG2 cells treated with 100μg/ml ellipin was decreased by 22.3% compared to the control cells. Also the number of adhered cells was reduced by Ellipin treatment. After 50μg/ml, 100μg/ml, 250μg/ml ellipin treatment, the number of apoptic cells were 14,6%, 45,6%, 100% of initial culture cells, respectively.Conclusions: Our results showed that the Ellipin suppresses HepG2 cancer cell proliferation and decreases migration and spreading activities and also inducts the cell apoptosis.

IntroductionThe detection of adverse drug reactions has become increasingly significant because of introduction of a large number of potent toxic chemicals as drugs in the last two or three decades. Adverse drug reaction (ADR) monitoring and reporting activity is in its infancy in Mongolia. The important reason is lack of awareness and lack of interest of healthcare professionals in ADR reporting and documentation.GoalTo evaluate implementation and trends of health care professionals toward adverse drug reaction reporting at first, second and tertiary level hospitals.Materials and MethodA prospective study was carried out in first and second level hospitals of Khentii, Dundgovi, GoviAltai, Selenge and Uvurkhangai provinces, Sukhbaatar, Songinokhairkhan district hospital and First maternaty hospital. From tertiary level hospitals were selected First national hospital, Third national hospital, National center of oncolgy, National center of traumatolgy. The questionnaire survey involved total of 175 doctors and pharmacists.ResultsThe study result have shown that most of health care profeesionals (76 – 80%) of first and tertiary level hospitals have known about legal bases and theie duties for the ADR reporting than health care professionals (69%) of secondary level hospitals. And, pharmacists more activily involve in ADR reporting than doctors. The main reasons of healthcare professionals ADR underreporting were lack of time to report, lack of awarness about ADR and not knowing importance of ADR repoting. The implementetion extent of ADR reporting was in tertiary level hospital better than in secondary level hospitals. Lacking of clinical pharmacists and clinical pharmacologists and unproper activitity of Drug therapeutic committee in secondary level hospitals were the reason of poor implementing and underreporting of ADR.ConclusionThe study result has shown that there is needed to encourage doctors to the adverse drug reporting activity and implementation of drug safety should be strengthen in each level of health care system.

Abstract To study adverse drug reactions registered in 2010-2012 in
Mongolia. This study has descriptive design. 280 yellow forms for
recording adverse drug reaction, which were registered by the Drug
assurance department of the Department of Health-Implementing
Agency of the Government, were used. Yellow forms were from 2010-
2012. Statistical analysis was performed in SPSS 17.0. More than half of
cases (51%) of drug adverse reaction were in people over 41 years old.
Psychotropic medications and antibiotics were the most drugs with
adverse reaction having 31.1% and 27.1% respectively. The common
adverse reactions were dysfunctions of central nervous system (38.6%),
skin rashes (22.5%), dysfunctions of digestive system (11.1%), allergic
reactions (7.9%) and other symptoms (15.5%). In 4% of cases the
symptoms were not described. Countries of production of medications
causing drug reactions were Russia in 26.1%, China 13.2%, Моngolia
12.2%, India 11.4%, Indonesia 3.2% and other countries in 15.3%. In
18.6% the country was not recorded. In 18.9%, 16.4% and 9.6% of
reactions were from tablets, intramuscular injections and drippings. The
forms filled in by the patients in 31% did not have their names, and in
48% there were no records on reasons for taking medicines. Conclusion
Psychotropic medications and antibiotics were the most drugs with
adverse reaction. The common adverse reactions were dysfunctions of
central nervous system, skin rashes and dysfunctions of digestive.
Adverse drug reactions were identified insufficiently and forms for
recording the adverse reactions were filled incompletely and incorrectly.

Background:
A drug related problem is defined by the Pharmaceutical Care
Network Europe Association as an an event or circumstance involving drug
therapy that actually or potentially interferes with desired health outcomes.
One critical aspect of preventing such errors is proper dose adjustment, which
plays a vital role in the diagnosis and treatment of disease. For instance, adjusting
the dose of warfarin based on the patient’s INR level is essential. In
a 1995 study conducted in England, clinical pharmacists recommended target
doses of angiotensin-converting enzyme (ACE) inhibitors for patients with
chronic heart failure. As a result, patients experienced a significant reduction
in pulmonary and peripheral edema, along with improved exercise test outcomes.
At the Mongolian-Japanese Hospital of the Mongolian Medical University
of Science and Technology, it is important to analyze dosage-related
issues identified by clinical pharmacists and inform healthcare professionals
about common dosage selection errors and associated risks.
Aim:
We analyzed issues related to medication dosage.
Materials and Methods:
A retrospective study was conducted to examine
problem related to dosage detected through prescription monitoring at the
Mongolian Japanese Hospital of the Mongolian National University of Health
Sciences from 2023 to 2024.
Results:
Out of a total of 2340 drug-related problem identified across five
inpatient wards during this period, 581 (100%) were related to dosage. Clinical
pharmacists performed prescription review on approximately 67% of all
inpatients, which was consistent between years. However, medication-related
problems tended to decrease from 41.1% (n=1499) in 2023 to 22.3% (n=841)
in 2024 (p=0.05). The majority of dose-related problems, 75.6% (n=440), were
overdoses. Medication-related problems were most common in the surgical
department, with 59.5% (n=346) (p=0.001). The most frequent dosage-related
errors involved exceeding the daily dose of diclofenac, administering higher-
than-recommended doses of ceftriaxone, failing to adjust cefotaxime for
renal function, and using inappropriate doses of metronidazole in patients with
impaired liver function. The leading cause of these errors was failure to adhere
to guideline-recommended dosing, which accounted for 71.3% (n=415)
of cases (p=0.001). When dosage-related recommendations were provided to
physicians before of treatment, acceptance rates increased by 14% (p=0.001).
These interventions resulted in an estimated cost saving of 1.267.219₮ and a
reduction of 363 injections.
Conclusion
Therefore, clinical pharmacist-led prescription review can help
reduce the risk of dosage errors, lower associated healthcare costs, and alleviate
the burden on medical staff.

Purpose:
To investigate the outcomes of ROP screening of retinopathy of prematurity (ROP).
Methods:
This was a prospective of prematurity infants screened ROP from 2020 April 13th to
April 28th 2020 and from 2020 June 08 th to June 22th 2020 and prospective cohort study of
premature infants with treatment-requiring ROP who received intravitreal injections, laser surgery.
Demographic factors, diagnosis and clinical course were recorded. Indirect ophthalmoscopy
and Retinal imaging was performed using RetCam (Natus Medical, Pleasanton, CA) and
images were taken. Each eye was evaluated by the pediatric ophthalmologist and aimag’s
ophthalmologist for the presence or absence of ROP, zone of vascularization, stage, plus disease,
and aggressive posterior ROP (AP-ROP). The diagnosis and classification of ROP for this current
study were determined by examination using indirect ophthalmoscopy, and treatment plans
were determined according to the International Classification for ROP and the Early Treatment for
ROP Study (ET-ROP).2,13
Results:
A total of 90 premature infants with BW ≤ 2000g and/or GA ≤ 34 weeks were screened for
ROP during the study period. 8 (8.8%) of the 90 infants screened required treatment. The 8 infants
who received ROP treatment had a mean GA of 28.5 ± 1.7 weeks, mean BW of 1237.5 ± 125.42g,
mean PMA of 36 weeks and mean follow-up time of 2 months.
Conclusion
After treatment, resolution of ROP was noted in approximately 100 % of the patients
who had treatment-requiring ROP.

Mongolian Medical Sciences 2023;205(4):75-83
Background:
Spinal Muscular Atrophy (SMA), an autosomal recessive disorder characterized by lower motor neuron
loss, leads to progressive muscle weakness and atrophy. With a neonatal incidence ranging from
1:6000 to 1:11000, individuals affected by SMA face challenges in locomotor function. The advent
of newborn screening tests, early diagnostic techniques, and the introduction of gene therapy have,
however, shown promise in enabling the acquisition of these motor skills.
Objective:
This review article seeks to shed a light on current understandings of the epidemiology, clinical
presentations, diagnostic methods, and treatments for spinal muscular atrophy, highlighting cutting
edge approaches within the discipline.
Methods:
A thorough search was conducted on PubMed, Cochrane, National Institutes of Health, and Web
of Science databases for recent research articles concerning SMA’s incidence, prevalence, clinical
manifestations, early detection, genetic testing and contemporary gene therapy.
Results:
The prevalence of SMA stands at 1-2 cases per 100,000 population, with an incidence of approximately
8 cases per 100,000 live births. Pre-1995 studies exhibited varying prevalence rates due to using non
molecular-biological methods, small localized populations, diagnostic errors, and regional characteristics.
Diagnosis involving Multiplex ligation-dependent probe amplification (MLPA), quantitative polymerase
chain reaction (qPCR), or next-generation sequencing (NGS) analysis to confirm SMN1 and SMN2
gene status aids in identifying carriers and SMA subtypes. Countries implementing newborn screening
programs have demonstrated early SMA detection in asymptomatic newborns, contributing to reduced
mortality and disability rates. Currently, several types of gene therapy are being used in the treatment
of SMA.
Conclusion
The epidemiology of SMA varies between countries and regions. It is fully possible to confirm the
disease, identify carriers and subtypes. The inclusion of SMA in newborn early detection programs is
crucial for reducing infant mortality and disability, and several gene therapies have received approval from relevant authorities for SMA treatment. In Mongolia, it is possible to introduce tests to confirm the
disease and determine carriers and subtypes.

Background:
Spinal muscular atrophy (SMA) is a degenerative neuromuscular disease that causes progressive
muscle weakness and atrophy due to the loss of the motor neurons. Approximately 95% of patients
with SMA are homozygous for the deletion of SMN1 exon 7. With an incidence of 1/10.000 and a carrier
frequency of 1/40 to 1/50, SMA is the most common genetic cause of death in infants.
Purpose:
To detect homozygous deletion of SMN1 exon 7 and to analyse the SMN1 copy number by molecular
genetic analysis.
Materials and Methods:
In this study, 3 SMA patients with SMN1 gene homozygous deletion and 17 people of their relatives were
included. Molecular genetic analysis was performed in the Central Scientific Research Laboratory of the
Institute of Medical Sciences. DNA was extracted from peripheral blood, and its purity was assessed by
spectrophotometer. Homozygous deletion of SMN1 gene was analyzed with allele-specific PCR, and
the SMN1 gene copy number was evaluated by real-time PCR.
Results:
Among the five participants diagnosed with SMA by clinical symptom and electromyographic test, three
cases were found to have homozygous deletion of exon 7 of the SMN1 gene, while two cases did not
exhibit such mutation by the allele specific PCR analysis.
The mean age of study participants was 27.76±16.07 (ranging from 8 months to 52 years).
Six of the 7 relatives of the first proband had 1 copy number of SMN1 (0.75±0.29) or were carriers
of SMA, while one had 3 copy numbers (2.99) or no deletion of SMN1 gene. Additionally, 6 of the 7
individuals of the second proband had 1 copy number of the SMN1 gene (0.72±0.14), and 1 person
had 2 copy numbers. All 3 relatives of the third proband had 1 copy number of SMN1 gene (0.96±0.37).
Conclusion
We consider that determination of SMN1 gene homozygous deletion and carrier testing
can be performed by the PCR method locally. Further, it is necessary to implement the molecular
genetic testing method into practice and to study the requirements and needs of early detection of SMA
in the newborn screening program of Mongolia.
