Randomized trial of three doses of vitamin D to reduce deficiency in pregnant Mongolian women.

BACKGROUND: In winter in Mongolia, 80% of adults have 25-hydroxyvitamin D (25(OH)D) concentrations <25 nmol/l (<10 ng/ml) and 99% have <50 nmol/l (<20 ng/ml). The vitamin D dose to avert deficiency during pregnancy in this population is unknown. METHODS: We conducted a randomized, controlled, double-blind trial of daily 600, 2000, or 4000 IU vitamin D3 for pregnant women in Mongolia (Clinicaltrials.gov #NCT02395081). We examined 25(OH)D concentrations at baseline (12-16 weeks' gestation), 36-40 weeks' gestation and in umbilical cord blood, using enzyme linked fluorescent assay. Sample size was determined to detect 0.4 standard deviation differences in 25(OH)D concentrations with 80% power. FINDINGS: 119 pregnant women were assigned 600 IU, 121 assigned 2000 IU and 120 assigned 4000 IU from February 2015 through December 2016. Eighty-eight percent of participants took ≥80% of assigned supplements. At baseline, 25(OH)D concentrations were similar across arms; overall mean ±â€¯standard deviation concentration was 19 ±â€¯22 nmol/l; 91% were < 50 nmol/l. At 36-40 weeks, 25(OH)D concentrations increased to 46 ±â€¯21, 70 ±â€¯23, and 81 ±â€¯29 nmol/l for women assigned 600, 2000, and 4000 IU, respectively (p < 0.0001 across arms; p = 0.002 for 2000 vs. 4000 IU). Mean umbilical cord 25(OH)D concentrations differed by study arm (p < 0.0001 across arms; p < 0.0001 for 2000 vs. 4000 IU) and were proportional to maternal concentrations. There were no adverse events, including hypercalcemia, attributable to vitamin D supplementation. INTERPRETATION: Daily supplementation of 4000 IU during pregnancy is safe and achieved higher maternal and neonatal 25(OH)D concentrations than 2000 IU. Daily 600 IU supplements are insufficient to prevent vitamin D deficiency in Mongolia. FUND: Anonymous foundation and Brigham and Women's Hospital.

Study of the Antischemin’s effect on immune response intensity / Монголын Анагаах Ухаан

Background@#The immune response has become the basic use of today’s medical and biological sciences understanding, definition and realization when first introduced into the cognitive level with new theory of nine step closed cycle of protons related to membrane potentials three linear and s-NCM. Medicinal preparations for the immune system derived from traditional herbs have rarely been used therefore, we aim to determine the boost-reduction of immune response with preparation Antischemin with ingredients of Gingko biloba, Astragalus membranaceus and Scutellaria baicalensis.@*Materials and Methods@#This study was carried out on the innovation-research bio-modeling laboratory of the “New Medicine Medical University”. Sheep blood was taken in heparin tube and centrifuged for 10min with speed of 2000rpm and plasma was isolated. Blood components were washed with physiological solution 3-4 times and 10% blood red cell suspension was prepared. Prepared 0.2ml of 10% sheep red cell suspension was injected to mice tail vein to create immune response model (N.K. Jerne and Nordin (1963)). IL-4 (pg), antibody titre SRBC-IgM(ng/mL), and hemagglutinin titre (%) was measured with ELISA kit and compared with control group. Comparing group animals used Salimon 1 ml/kg, Dexamethasone 1 mg/kg orally. The study was conducted in accordance with the approval of Ethics Review Committee of Ministry of Health (November 02, 2018 and approval number 10, №1).@*Result @#In addition, comparing mice which used Antischemin 100 mg/kg orally with sheep blood injected group at day 5, IL-4 level increased by 12.11%, but conclution of antibodies against sheep blood-IgM concentration decreased by 28.7%, and hemagglutinin titre decreased by 27.5%, meaning we observed that the preparation can suppress immune response.@*Сonclusions@#Antischemin preparation meaning observed can suppress immune response.

The inhibitory effects of rotenone, 2, 4-dinitrophenol, oligomycin on the electron proton flow through “The membrane redox potential three state line” / Монголын Анагаах Ухаан

Rotenone is a specific inhibitor of the NADH dehydrogenase complex. In mitochondria, rotenone inhibitsthe oxidation of NADH to NAD, thereby blocking the oxidation of NAD and the substrates such asglutamate, alpha-ketoglutarate, and pyruvate. Rotenone also inhibits the mitochondrial respiratory chainbetween diphosphopyridine nucleotide and flavine.2, 4-Dinitrophenol – (DNP) is lipophilic weak acids that pick up a proton, transport across the mitochondrialinner membrane into the matrix, deprotonate, then exit as anions before repeating the catalytic cycle,and dissipating the proton gradient. In this situation, electrons continue to pass through the electrontransport system, reduce oxygen to water and metabolic rate, heat are increased, but ATP is lesssynthesized in this process.The macrolide antibiotic - oligomycin binds to the surface of the c8-10 ring of the Fo domain of ATPsynthase, making contact with two neighboring molecules and blocking proton flow, which explains theinhibitory effect on ATP synthesis. Intraperitoneal injection of oligomycin into the rat (0.5 mg per kg)reduces the oxygen consumption by about 50%; decreases ATP production by the aerobic pathway andincreases formation of lactate in blood serum. These changes may cause a decelerated metabolism andan increased formation of free radicals or ROS in membranes.

Mode of energy and metabolism which related to three state line systems of membrane-redoxy potentials and rlung, mkris, badgan symbolic coded / Монголын Анагаах Ухаан

Background. This study is to determine mode of metabolism on triple collaboration bridges of traditional medicine, modern medicine and NCM.Goal. To determine membrane redoxy potentials three line involves important regulation factors on mode of metabolism which relationship connected with rlung, mkris, and badgan symbolic code.Materials and Methods. Only 81 healthy individuals were involved in the study. Proton leak was determined by quantity rate of MDA in cell membrane and membrane resistance, proton conductance was determined by serum and urine oxidase activity.Results. The table 1 shows quantity rate of membrane resistance was decreased 1.08-1.52 fold, HDL content was decreased, and however LDL was increased. This result is to manifest low proton leak which means this type is likely belonged to badgan symbolic code with qualities cold fatty, earth, water. The table 2 shows serum and urine oxidize activity 2.22-6.1 fold was increased, HDL content was increased; UCP-3 gene activity relatively was increased. This result is to manifest highproton conductance which means this type is likely belonged to mkris symbolic code with qualities hot fatty, fire.Conclusions:1. Individuals with high proton leak and slow proton conductance had serum and urine oxidize activity were weak, therefore there are visceral and subcutaneous fat were low.2. Individuals with medium proton leak and high proton conductance had serum and urine oxidize activity were high, therefore there are visceral was low and subcutaneous fat was high.3. Individuals with weak proton leak and medium proton conductance had serum and urine oxidize activity were medium, therefore there are visceral was high and subcutaneous fat was low.

Reduction of tuberculosis burden among prisoners in Mongolia: review of case notification, 2001-2010.

Documentation on the TB situation in prisons in developing countries is limited, and very few studies have quantitatively evaluated TB control programmes in prisons. This study aimed to evaluate TB control in Mongolian prisons by analysing routine programmatic data. The TB caseload in prisons has significantly diminished in the last decade, synchronised with policy and programmatic development, including systematic entry screening on detention and after conviction, and improved living conditions. Improved case detection during entry screening may have contributed to the significant reduction of the TB caseload in prisons.
