BackgroundThe preparations of multi-component have been the subject of chemical study for a long time. Therefore, when compounding the preparations of multi-component in traditional medicine, their taste is cautiously relied on, as the power of the one medicine should not be subdued with the power of another. Additionally the properties of the components and their regulating effects on the body systems are also considered. Our research group has been carrying out tests for raw materials,which are contained in multi-component preparations. However, it is a necessity to conduct phytochemical study on multi-component preparations in order to isolate pure biological active compounds and to identify their structure as well as to quantify its amount by modern techniques of analysis.GoalThe aim of the present study was to isolate pure biological active substances from Mongolian traditional medicine Garidi-5 and to elucidate their structures, which was used in Mongolian traditional medicine for the treatment of inflammation and as a pain relieving remedy.Objectives:1. To isolate pure substances from Garidi-5 and carry out tests to identify and determine their structure2. To quantify the amount of biological active substances.Materials and MethodsMongolian traditional medicine Garidi-5 has been selected as a biological natural product for the study. Garidi-5 is a traditional Mongolian medicine consisting of 5 medicinal herbs, namely Terminalia chebula Retz., Aconitum Kusnezoffii Reichb., Acorus calamus L., Saussurea lappa L., and musk of Moschus moschiferus and manufactured in the Drug factory of Traditional Medical Science Technology and Production Corporation of Mongolia. In this research, in order to determine the total content of phenolic compound was used the Folin–Ciocalteu method, which based on performing dark blue color complex compound. Isolated substance identification was determined by the TLC, UV and IR spectrophotometric methods. Inaddition it was checked melting point of the isolated substance. Determination of Gallic acid30g Garidi-5 was macerated in 60ml 80% methanol at room temperature for 24 h. After extraction, the extract was concentrated and vacuum evaporated. Different solvents from hexane, chloroform, ethyl acetate and n-butanol were used for theexperiment. All the extracts collected, evaporated and chromatographed on Silica gel column. Future purification of active fractions on Silica gel with methanol yielded the compound G1 which was further characterized as Gallic acid. Total phenolic content was determined spectrophotometrically according to the Folin–Ciocalteu’s method with slight modification. Gallic acid was used as a standard phenolic compound. Briefly, 1 ml of extract solution contains 1 mg extracts, in a volumetric flask diluted with distilled water (46 ml). One ml of Folin-Ciocalteu reagent was added and the content of the flask mixed thoroughly. After 3 min, 3 ml of Na2CO3 (2%) was added and then the mixture was allowed to stand for 2 h with intermittent shaking. The absorbance was measured at 760 nm in a spectrophotometer. All measurements were performed in triplicate.ResultsIn this research, TLC method on silica gel plates was used in order to identify the biological active pure substances from Garidi-5. Preliminary TLC experiments indicated the presence of Gallic acid in Garidi-5, which was isolated by column chromatography by comparing with reference standard substance (Gallic acid). Gallic acid was determined in the solvent system benzole-ethyl acetateformic acid- acetone (5:5:2:0.5) in isolated substance (G1). It showed blue color, Rf =0.65, on TLC plate. [1] For the characterization of two samples it was carried out IR analysis for each. In the IR spectra of G1 and standard substance can be recognized by the following absorption frequency regions: 700-900 cm-1 for Car-H; 1000-1300 cm-1 for vibration of bonds in various oxygen containing groups, 1350-1470 cm-1 for vibrations of –CH, -CH2 and –CH3 groups; 1500-1630 cm-1 for skeletal vibrations of aromatic rings, >C=O bonds; 2800-2950 cm-1 for stretching vibrations of –CH, -CH2 and -CH3 groups in saturated aliphatic structures; and 3030-3350 cm-1 for stretching associated vibrations of -OH groups in aromatic rings and aliphatic structures. As a result it was revealed that both IR spectra of G1 and standard substances were similar. [3]Further for the characterization of two samples it was carried out UV analysis of each. In the UV spectra of G1 and standard substance can be recognized by the following absorption frequency regions: 260-280nm for benzole groups; 200-225nm for carbonic acids; 400-770nm >C=O bonds, which reveal the presence of Gallic acid. In addition, melting point of isolated substance G1 was analyzed and detected at 2410C, which was similar to the standard substance’s melting point. [4]Moreover, Mongolian traditional medicine Garidi-5 contains 24% of the biological active substance (total phenolic compounds). [2]Conclusions:As a result of current study on Mongolian medicine Garidi-5, it was isolated one essential substance from ethyl acetate fraction. The phytochemical analysis reveals the presence of Gallic acid in Garidi- 5, which was determined by thin layer chromatography, UV and IR spectrophotometric methods. Mongolian traditional medicine Garidi-5 contains 24% of the biological active substance. Thus, the isolation of Gallic acid from multi-component preparations and identification of its structure was first phytochemical study conducted in our laboratory.

Introduction:According to studies range by the World Health Organization in 2010, 278 million people are deaf or hearing impairment, out of which 24% use an hearing aid and one out of every 10 people has been treated with surgical method and 9 people’s hearing loss has been restored using acoustic treatment method.Purpose:Our purpose is to define noisy vowels of Mongolian word, which will be used for configuration of hearing aid, thereby improve hearing ability.The objectives1. Analyze spectrogram for noisy sound of Mongolian word and define frequency and level of noisy words.2. Define average difference of listening level of the noisy sounds of Mongolian language using “Listening field of Mongolian word”Materials and method:We did the spectrogram for noisy sounds of the Mongolian word using voices of 62 people including male and female children as well as adults. Also, we analyzed frequency energy of all vowels noted in the 60-65 dB computer, via the “PRAAT” software, which defines analysis of speech in phonetics and studied listening level of the strong vowels using listening sphere of word.Result:During our studies, we selected the vowels [a], [e], [u], [o] [a], [ʊ], [ɔ], [i] and defined spectrogram and energy concentration (formant) of each vowel to define the vowels with the highest energy, and further found out that distance difference of the spectrogram of each vowel and frequency between vowels as 300-780 Hz. On the other hand, difference between spectrogram of each strong sound such as [sh], [s], [v], [z], [dj], [kh] has been defines as 340-2800 dB.When we observed the words with strong sound in the listening field of Mongolian words, which were 3- 5 dB lower than the clearer words.Conclusion:1. According to spectrogram, noisy sound [sh], [s], [z], [dj] has frequency of 3300Hz-3500Hz, which is noisier and resulted in poor acoustic listening ability. Further, we found out that Distant difference of vowels of Mongolian language [a], [e], [o] and consonants [m], [n] is far, accordingly, acoustic listening ability has been good, on the other hand, distant difference of vowels of Mongolian word [ʊ], [ɔ], [u] is near or close, accordingly, acoustic listening ability has been not well.2. Level of distinquishment of the noisy sounds of Mongolian word has been lower by 3.6+ 0.8Db to 5.2+1.2Db at levels of clear sound to feedback.

Innovation 2021;14(1-Ophthalmology):14-17
Background:
Retinal pathologic features are associated with inflammatory processes and
endothelial dysfunction, leading to circulatory abnormalities and reduced vascular reactivity.
Both retinopathy and nephropathy involve thickening of basement membrane and muscular
layers and increased leakage. These pathologic and hemodynamic abnormalities may occur
throughout the body and their effects on the retinal vasculature may be useful indicators of
cumulative microvascular damage from hypertension, inflammation, diabetes mellitus, and other
processes. Type 2 MPGN is an uncommon renal condition associated with electron dense deposits
in the lamina densa of the glomerular basement membrane with C3 found in the capillary loops
and mesangium. The deposits in the basement membrane can lead to a breakdown of the
blood-retinal barrier by interfering with the RPE layer, and type 2 MPGN has been described in
association with central serous retinopathy.
Purpose:
To assess the retinal findings in end stage of Chronic kidney disease (CKD) and diabetic
renal failure
Methods:
Data of diabetic renal failure (n=20, mean age 56.8±11.6), and end stage of CKD(n=83,
mean age 48.2± 11.6) were cross-sectional analyzed. Nonmydriatic fundus photographs of the
disc and macula in both eyes were obtained in all the subjects. The photographs were assessed
by ophthalmologist using the standard protocols. The following parameters were recorded:
BCVA, IOP, BP GFR, serum Creatinine, ophthalmic and fundus examination.
Results:
Greater severity of retinopathy was associated with DM. The presence of vascular
abnormalities usually associated with Diabetes Mellitus ( DM) and was not associated with lower
estimated glomerular filtration rate. All of patients with DM (n=20, 100%) ,they have Diabetic
retinopathy. We found sight direct relationship between retinal posterior pole deposit with CKD
patients. Some of patients who have end stage of CKD, (n=18, 11%) they have retinal deposit on
their posterior pole.
Conclusion
Our findings show ,In participants with end stage of CKD, there was no significant
severe retinopathy. In summary, our study demonstrates that DM, is one of the leading cause of
irreversible vision loss. Every patients with DM need the ophthalmic follow up examination in every
six months.

Health Laboratory 2021;13(1):5-11
Description:
Asymptomatic bacteriuria is defined as the presence of 1x105 or more bacteria per milliliter of urine, although there are no signs of UTI [1]. Asymptomatic bacteriuria is quite common and occurs in 1-5% of healthy women before menopause. The incidence of asymptomatic bacteriuria increases in the elderly (men and women) to 4-19%. Asymptomatic bacteriuria is observed in 0.7% -27% of patients with diabetes mellitus, in 2-10% of pregnant women and in 23-89% of patients with spinal cord injury. Asymptomatic bacteriuria is rarely observed in young men and always requires differential diagnosis with chronic bacterial prostatitis[2].
Among the elderly, those in institutionalized settings such as long-term care facilities and hospitals have a higher prevalence of asymptomatic bacteriuria than those living in the community. Therefore, interest in asymptomatic bacteriuria has shifted from the general population to these groups of individuals. The prevalence varies from 2% to 10% in pregnancy and from 15% to 50% in the elderly in long-term care facilities.[3,4]
This study was undertaken to determine the prevalence of people asymptomatic bacteriuria in among hospitalized people.
Purpose:
Investigate cases of asymptomatic bacteriuria among hospitalized individuals and determine antibiotic susceptibility by type of pathogen detected in urine.
Materials and methods:
This cross-sectional study in the “I” Hospital of UB city, Mongolia. We conducted into the study 133 patients. After obtaining informed consent, a midstream clean-catch urine sample was collected in the same 24 hour time window and was evaluated for urinalysis using a dipstick test and routine culture. A positive urine culture was defined as a single urine sample with microbal growth of >105 colony- forming units of a single organism. We use 5-10% Blood agar, UTI agar, Mackkong agar and Chroma agar for a bacterial growth. Then we did antibiotic susceptibility of the determined pathogen.
Result:
The average age of the respondents was 55.9±14.6, the youngest was 17 years old and the oldest was 91 years old (CI 95% 53.4-58.5). By age group, 4.5% (n = 6) of people aged 20-30, 21.1% (n = 28) of people aged 31-45, 37.5% (n = 50) of people aged 46-60, and people over 61 years of age 36.8% (n = 49) respectively.Of the respondents, more than 56 or 54.9% (n = 73) were elderly, of which 63.9% (n = 85) were women and 36.1% (n = 48) were men.
A total of 36 (27.1%) leukocytes were detected, and 25 (34.2%) more (P-0.05) were detected in people over 56 years of age. The protein detected in 24 (18.0%) people, all over 56 years of age and more defined in men (P-0.01).
80.5% (n = 107) of those surveyed were diagnosed with the pathogens, and 54.9% were elderly (P-0.031). 82.4% of women and 77.1% of men were diagnosed with urinary pathogens.
Streptococcus 26%, E.coli 19%, Saprophyticus 13%, Enterococcus 11% and Staphylococcus 11% were detected in the analysis, and Streptococcus and E.coli (19%) accounted for a slightly higher rate of infection.
A total of 13 types of pathogens were identified, of which 53.4% were susceptible, 21.7% were moderately sensitive, and 24.9% were non-susceptible.
Discussion:
According to a study conducted by researchers at the University of Taiwan, the prevalence of asymptomatic UTI-s in the general population is 57.8%. E.Coli was also the most common bacterium in the urine [6].
In our study, there are many cases of E. coli.
Study in the United States found that the prevalence of asymptomatic bacteriuria among inpatients was 8.5%, all of them women. The most common pathogens in this study are Enterococcus bacteria. This study found that 1 in 10 people admitted to the hospital may have asymptomatic bacteriuria. [1]
Conclusion
1. Asymptomatic bacteriuria in 80.5% of those surveyed 54.9% were detected in people over 56 years of age.
2. Antibiotic susceptibility of the tested pathogens was determined as 53.4% sensitive, 21.7% moderately sensitive and 24.9% insensitive.

Background:
The incidence of acute SAH has been estimated at 2–22 cases per 100 000 persons per year. The
most common cause of basal acute SAH is a ruptured cerebral aneurysm. Cerebral vasospasm in
the first 2 weeks after aneurysmal subarachnoid hemorrhage is recognized as a major predictor of
delayed cerebral ischemia. From 2014 through 2018, 5272 patients with a stroke (amongst them
20.4% were patients with aSAH) were hospitalized in the 3rd State Central Hospital of Mongolia.
Objective:
To study the clinical features of the cerebral vasospasm and dopplerosonography parameters in the
aSAH patients.
Materials and Methods:
The methods, methodology and ethics of the research work were discussed at a Research meeting
of Ethics Control Committee of the Mongolian National University of Medical Sciences held on
December 22, 2017 (No2017 / 3-05), and the study was performed in accord with approval.
60 patients with aSAH (hospitalized from 2017 to 2018 year) were enrolled in the case-control
study. Informed consent were obtained from each participants. Clinical condition of participants was
classified by Hunt-Hess scale (HHS). Cerebral vasospasm degree was graded by Lindegaard index.
Results:
52.5% of the participants were men and 47.5% were women. Average age was 49.9±12. When clinical
condition degree was compared to vasospasm grade it was revealed that amongst 1st degree of
Hunt-Hess scale (HHS) group 11.1% of enrolled patients’ spasm was normal or had no spasm, while
it was observed either 44.4% mild and moderate spasm. In the 2nd degree of HHS group: normal in
6.9%, mild in 3.4%, moderate in 86.2%, and severe spasm was in 3.4%. In the 3rd degree of HHS
group, 11.1% had no spasm, moderate spasm was in 77.8%, and severe spasm was in 11.1%. In 4th
degree of HHS group, 71.4% were with moderate spasm, 28.6% were with severe spasm (p = 0.001).
When the Hunt-Hess Scale was compared to the Sinus Rectus 1st degree of Hunt-Hess scale (HHS)
group Sinus Rectus was normal for 22.2% patients, mild for 66.7% and severe for 11.1%. Though 4th
and 5th degree of Hunt-Hess scale (HHS) groups’ Sinus Rectus mild for 7.1% normal, 50.0% mild
and 42.9% severe (p=0.007). Thus whenever the clinical condition worsened the cerebral intracranial
pressure was increasing.
Conclusion
aSAH patients clinical complication degree were directly associated with the cerebral vasospasm
revealed by the transcranial dopplerosonography. Therefore, the evaluation of Hunt-Hess scale has
an important significance in the prevention from clinical complications and in the selection of the
appropriate treatment approaches for aSAH patients.

Abstract
Mana-4, an herbal medicine, had been used to treat incomplete-mannered and infection-caused hot disease in Mongolian traditional medicine. It has already reported that Mana-4 acts as an anti-inflammation agent, an activator of T and B cells, an immune-modulator and an inducer of cellular proliferation. Moreover, it enhances the immune system and energy level of human body.
It was confirmed that the main active compounds in Mana-4 are inulin and total flavonoids which are effective for many diseases. Drug formulation types are very important to delivery the drugs to the targeted tissues and organs without loss of active ingredients. Total flavonoids in the extract of Mana-4 and granulated Mana-4 was qualitatively evaluated by TLC and yellow-brown spots (Rf was 0.4) were found on TLC plates, indicating that the preparations contained flavonoids. Also, it confirmed that the appropriate extractor of total flavonoids from Mana-4 was 70% of ethanol. In conclusion, the tablet formulation from Mana-4 was successfully prepared and the quality requirements was allowable.
