Study on sarcopenia comparing muscle mass, body mass and height / Монголын Анагаах Ухаан

Introduction@#Sarcopenia is a prevalent condition characterized by decrease in muscle strength and loss of body function which result from the decrease of muscle mass in older age. In 2014, the Asian Working Group for Sarcopenia developed the diagnosis criterion for sarcopenia. The measurements were changed to accommodate for the physical characteristics of asians. The loss of muscle mass increases after age 40 and decreases by 8 percent every 10 years. After age 70 this number is increased to 15 percent every 10 years. @*Goal@#Assess the prevalence of sarcopenia among men by comparing body height and mass@*Materials and Methods@#The study included 196 older men aged 40 and above chosen by random sampling from the geriatric and rehabilitation cabinets of the Mongolian National Gerontology Center. </br> Sarcopenia diagnosis was made based on the criteria from the Asian Working Group for Sarcopenia using methods by Janssen I and others to compare body mass and height.@*Results@#Comparing body muscle mass and height 11.7 percent of participant aged 40-86 had sarcopenia. When comparing body muscle mass and weigth 33.2 percent had sarcopenia.@*Conclusion@#Determining sarcopenia among Mongolian men by comparing muscle mass and body mass resulted in 33.2 percent sarcopenia. When compared with height, 11.7 percent had sarcopenia.

Some hormones changes in women with polycystic ovary syndrome / Монголын Анагаах Ухаан

IntroductionPolycystic ovary syndrome (PCOS) is the most common endocrine disorder of reproductive-age women,affecting an estimated 5-8% of all women in this age group. Clinically, hyperandrogenism, chronicanovulation, central obesity and polycystic ovary can all occur in women with PCOS and may causeof infertility. Dehydroepiandrosterone sulfate is an androgenic hormone which produced from adrenalcortex and recently, there is no any data determined DHEA-S in patients with PCOS.GoalOur study was designed to determine serum DHEA-S and other hormones in women with PCOS.Materials and MethodWe have used a cross-sectional study design and the study included reproductive-age 18 women withPCOS. ELISA test to determine serum DHEA-S and other sexual hormones was analyzed for all of thesewomen.ResultWhen we analyzed ELISA test to determine serum DHEA-S and other sexual hormones, DHEA-S level8.0±2.1 μg/ml, LH level 9,45±4,3 mlU/ml, FSH level 5,04±1,1 mlU/ml, prolactin level 19,78±12,2 ng/ml, E2 hormone level 16,8±8,9pg/ml, testosterone level 0,25±0,1 ng/ml were in women with PCOS,respectively.

Plasma level of Apolipoprotein A for coronary artery disease / Монголын Анагаах Ухаан

IntroductionCoronary artery disease is a leading cause of death among men and women globally. Researchershave focused on apolipoproteins for coronary artery disease (CAD) than traditional lipid parameterssuch as total cholesterol, LDL-C and HDL-C. Measuring Apolipoprotein B (Apo-B) provides a directestimate of the total number of atherogenic particles. Also lipoprotein (a) [LP (a)] is super atherogeniclipoprotein that resembles the LDL containing apo-B in its structure and associated with development ofatherosclerosis and thrombogenesis.GoalTo determine some specifi c lipid markers such as apo-B, LP (a) and traditional lipid parameters forcoronary atherosclerosis and compare with healthy groupMaterials and MethodsHospital based case control study. The study included 42 patients undergoing coronary angiographywith >75% narrowing of main coronary arteries and 43 healthy controls. We collected data of traditionallipid parameters by “endpoint” method and apo-B, LP (a) by “immunoturbidometry method” from ROCHECOBAS 6000 analyzer series.ResultÀpo-Â and Lp(a) were 108.88±26.61 mg/dl, 19.50±24.86 mg/dl and signifi cantly higher in patientswith coronary artery disease (CAD) versus control group. Total cholesterol, especially LDL-C thatApo-B is major on its surface signifi cantly different in the study groups (p<0.05). Also, other lipoproteinthat containing apo-B, one of them is LP (a) were higher in the case group (p≤0.05) compared withhealthy controls. Logistic regression analysis showed that Apo-B were one of main risk factors for CAD(OR=1.024, p=0.013).ConclusionOur fi ndings suggest that LDL-C

Relationship between bone density, and hormonal and mineral healthy aging of Mongolians / Шинэ санаа Шинэ нээлт

To measure hardness of bone density, and study its relationship with serum calcium, phosphorus, Calcitonin levels and urine calcium level.Pre-designed questionnaire is used to reveal any risk factors associated with osteoporosis and also BMI is evaluated based on measurements of weight, height, bust and waist circumference. Study participants were measured their bone mass density of wrist and shin by ultrasound ( Sunlight MiniOmni, Beammed, USA). Serum calcium and phosphorus levels were analyzed by automatedbiochemical analyzer, Integra 800, according to the adhered protocol to the machine. New, clean urine containers were distributed to participant a day before urine test day and middle part of urine is collected into the container. The urine calcium level was analyzed by automated biochemical analyzer, Cobas Integra 800, according to the machine protocol. Calcitonin level was analyzed by ELISA kit by Eu cardio company of United States.Total of 80 people ages 26 to 87 from Ulaanbaatar were participated for this study. 29 (36.3%) ofthem were males whereas, 51 (63.8%) of them were females. Serum calcium average level was2.0+-0.2mmol/L, serum phosphorus average level was 0.8+-0.1mmol/L while urine calcium level was 3.9+-2.5mmol/L. According to our result, bone mass density was related to age (r=-0.495), serum calcium level has statistically important relationship (p<0.05) with bone mass density (r=-0.326), age(r=0.277), serum phosphorus (r=0.351), and urine calcium level (r=-0.316). Measurement above did not have statistically important relationship with Calcitonin level.Osteoclast might be dominating in osteoporosis since bone mass density is decreasing while serum calcium level is increasing along with aging.

SOME RESULTS FROM SERUM DEHYDROEPIANDROSTERONE SULFATE HORMONE DETECTION IN REPRODUCTIVE-AGED WOMEN WITH PCOS AND HEALTHY / Шинэ санаа Шинэ нээлт

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder of reproductive-age women, affecting an estimated 5-8% of all women in this age group. Clinically, hyperandrogenism, chronic amenorrhea, central obesity and polycystic ovary can all occur in women with PCOS and may cause of infertility. Dehydroepiandrosterone sulfate is an androgenic hormone produced inadrenal cortex and recently, there is no any data determined DHEA-S in patients with PCOS.Our study was designed to evaluate obesity, central obesity, hirsute grade and infertility and to determine serum DHEA-S hormone in women with PCOS and healthy non-PCOS women.We have used a cross-sectional study design and the study included reproductive-age 36 women, of whom 18 were diagnosed with PCOS and 18 were non-PCOS. Anthropometric components were measured and ELISA test to determine serum DHEA-S hormone was analyzed for all of these women. When we analyzed ELISA test to determine serum DHEA-S hormone, DHEA-S level was2.9±2.0 µg/ ml in non-PCOS reproductive-age women and 8.0±2.1 µg/ml in women with PCOS, respectively (р=0.01). Among the women diagnosed with PCOS had higher incidence of central obesity and grade II hirsute and infertility than healthy women (p=0.001). By the result, higher level of serum DHEA-S in women diagnosed with PCOS may cause of sign of hyperandrogenism such as central obesity, infertility and hirsute.

Results of investigation of lactate dehydrogenase activity in blood serum of mongolian population / Эрүүл мэндийн лаборатори

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.

Changes luteinizing hormone in aging female / Монголын Анагаах Ухаан

Introduction. Luteinizing hormone is slowly increasing in menopausal transition phase, it’s maintain to increase till early post menopause phase (Gore et al. 2004). It is related to steroid hormone’s negative feedback and estradiol’s positive feedback (Rossmanith 1995), and in addition, recently years kisspeptin-10 of hypothalamus [1]. LH is dramatically decreasing at the rather late of post menopause phase (Hall et al. 2000, Gill et al 2002). By the year 2030, more than 1.2 billion women in the world will be at least 50 years old. This increasing proportion of the female population will be experiencing the menopausal transition with its accompanying physiology and pathophysiology [2]. Recently researchers more focused to study the comparative analysis of hormones at the menopause phase in different ethnic groups. This kind of study have not implemented in our country yet.Goal.Determination of serum LH level changes in relation to aging. Materials and Methods. In this study were involved 161 healthy Mongolian women aged above 35 years. Subjects were randomly selected and undergone physical examination by geriatrician. People, who are receiving hormone replacement therapy, using in proper use of alcohol, injured and had survey, were excluded from our study. Blood samples were collected in the morning 8.30-10.30 AM, after a night fasting. Blood was separated immediately by centrifugation, then obtained sera were stored at -20 0C until assayed by ELISA kit from United Biotech CoLTD, USA, which sensitivity is 1mlU/ml. Statistical analyses have been performed by statistical software SPSS 17, using ANOVA, Pearson correlation.Results. Average level of LH was 29.95±3.31mIU/ml, 15.87±5.86mIU/ml at the age 35-45, 33.12±7.1mIU/ml at the age 46-55, 15.87±ImU/ml at the age 56-65, 38.15±6.6mIU/ml at the age 66-75, and 56.42±11.1mlIU/ml over 76 age in the all participants, considering by person correlation coefficient, between age and LH are moderate and direct correlation (r=0.264, ð 0.003).Conclusion. Average level of LH was 29.95±3.31mIU/ml in women aged over 35. Considering by person correlation coefficient, between age and LH are moderate and direct correlation (r=0.264, ð 0.003). LH increases with aging till round 70 and decreases after 70 years.

Change of follicle stimulating hormone and estradiol levels in aging women and their relevance / Монголын Анагаах Ухаан

Background:In females reproductive system aging is very important. Females spend the last 1/3 period of their life in insufficiency of sex hormone of late menopause. Due to decrease of ovary function noticeable change is detected in nervous endocrine system. Although menstrual cycle hasn’t been lost amount of FSH increased. It shows decrease of reproductive function females. Therefore recently researchers define that amount of FSH increase is an important biomarker which detects in an early period of menopause. But amount of estradiol hormone is almost in normal level until the late post menopause. Goal: to study the dynamic feature of age related changes and dependence of serum FSH and estradiol level in female aging.Materials and Methods:In this study were involved 177 healthy Mongolian women aged above 35 years old. We drained 5 ml fasting vein blood at 8.00-10.00 am. Sera were separated and kept frozen until assayed by ELISA. Results:Аaverage mean of FSH was 19.84±22.6 IU/l, at the age of 35-45 1.62±3.29 IU/l, at the age of 46-55 16.39±15.39 IU/l, at the age of 56-65 31.38±33.69IU/l, at the age of 66-75 28.83±17.31 IU/l, over 75 34.52±13.94 IU/l and there was positive correlation between age and FSH levels (r=0.647, p75 years) groups, mean estradiol level declined by 20.6 times, whereas FSH increased by 21.3 times. It shows that this is an important marker of menopause. Multiple regression analysis shows that age (β= -0.350, p<0.001) and FSH (β= -0.222, p=0.016) had had significant inverse correlation with serum estradiol level.

Changes follicule stimulating hormone in ageing / Монголын Анагаах Ухаан

INTRODUCTION: Gonadotropins are released under the control of gonadotropin-releasing hormone (GnRH) from thearcuate nucleus and preoptic area of the hypothalamus. The gonads — testes and ovaries — are the primary targetorgans for LH and FSH. The gonadotropins affect multiple cell types and elicit multiple responses from the targetorgans. As a simplified generalization, LH stimulates the Leydig cells of the testes and the theca cells of the ovaries to produce testosterone (and indirectly estradiol), while FSH stimulates the spermatogenic tissue of the testes andthe granulosa cells of ovarian follicles.Reproductive aging is endocrinologically characterized by a progressive rise in serum FSH levels associated with adecrease in serum estradiol (E2) and testosterone (T) levels. The rise in FSH is associated with reduced levels of sexsteroid and peptide negative feedback regulators of FSH secretion.The aim of study is: determination of serum FSH level changes in relation to aging and sex.MATERIALS AND METHODS: In this study were involved 169 healthy Mongolian adults aged above 45 years old. Subjectswere randomly selected and undergone physical examination by geriatrician. People, who are receiving hormonereplacement therapy, using inproper use of alcohol, injured and had surgery were excluded from our surgery. Bloodsamples were collected in the early morning (8.30–10.30 AM) after an all night fast and plasma was separatedimmediately by centrifugation; then sera obtained were stored at -20°C until assayed by ELISA kit from United BiotechCoLTD, USA, which sensitivity is 1mIU/ml. Statistical analyses have been performed by statistical software SPSS 16,using ANOVA, Pearson correlation, T-test.RESULT: Mean level of FSH for both sexes was 21.19±16.2 mIU/ml, which is in comparison with males (12.33±10.58mIU/ml) it was comparatively higher (p0.05), but in women it was stronger correlation (r=0.203, p<0.05). in 51-60 years age group FSH wasincreased by 56%, in 61-65 years group by 91%, in 66-70 years group it was increased 100% in comparison with until50 years age group. In older age (above 70 years) it decreased to 70% from reached concentration. ANOVA analysishas not showed significant difference between age groups.CONCLUSIONS: Average mean of FSH in old age are: 29.61±16.15 mIU/ml in women and 12.33±10.58 mIU/ml in men.Correlation with aging was observed stronger in women than in man (r=0.203, p<0.05). FSH increases with aging untilround 70 and decreases after 70 years old.
