Polymorphism at the dopamine transporter gene (DAT1) in populations of the Volga-Ural region was examined by means of polymerase chain reaction. Statistically significant differences in the dopamine transporter gene allele and genotype frequency distribution were revealed both between the populations belonging to one ethnic group and between the populations from different linguistic families. 相似文献

The MspI restriction polymorphism of the serotonin 2A receptor gene (5HT2A) was typed in populations of the Volga-Ural region (Bashkirs, Chuvashes, Tatars, Udmurts, Maris, Mordovians, Komis, and Russians inhabiting the Republic of Bashkortostan). Population-specific patterns of the main polymorphism indices distribution were established. Specific trends in the changes of genotype and allele frequency of the 5HT2A gene depending on the ethnicity of the population were revealed. 相似文献

Analysis of the content of CD16/32+, CD4+ and CD8+ -cells was perfomed in the peripheral blood and spleen ofmice of the ASC strain with high predisposition to depressive-like state in comparison with mice of parent CBA strain having no depressive behaviour. In both cases, ASC mice showed a decrease in the percentage of CD16/32+ and CD4+-cells along with an increase CD8 cells and lowering of immunoreactivity index (CD4+/CD8+). Changes in cellular subpopulations found in intact ASC mice was accompanied with animals' low capacity to respond to T-dependent antigen: sheep red blood cells at the dose of 5 x 10(8). In contrast to CBA mice the percentage and absolute number of IgM-antibody-forming cells were significantly decreased in the spleen of ASC mice on the 4th and 5th days after immunization as well as the numbers of IgG-antibody-forming cells on the 6th day of the immune response. Possible mechanisms underlying the immune reactivity inhibition under depressive-like state are discussed. 相似文献

Population genetic survey of the indigenous populations of the Marii El Republic, represented by the two major ethnographic groups of Maris, Meadow (five samples from Morkinsk, Orshansk, Semursk, Sovetsk, and Zvenigovsk districts) and Mountain (one sample from Gornomariisk district) Maris, was carried out. All Mari groups were examined at nine polymorphic DNA loci of nuclear genome, VNTR(PAH) (N = 422), STR(PAH) (N = 152), VNTR(ApoB) (N= 294), VNTR(DAT1) (N = 363), VNTR(eNOS) (N = 373), ACE (N = 412), IVS6aGATT (N = 513), D7S23(KM.19) (N = 494), and D7S8 (N = 366). Allele and genotype frequency distribution patterns were obtained for individual samples and ethnographic groups, as well as for the ethnic group overall. In each of six Mari samples examined, the deficit of heterozygotes was observed, i.e., the mean observed heterozygosity was lower than the expected one. The indices of mean heterozygosity, Hs = 0.455, and interpopulation differentiation, FST = 0.0024, for the Mari gene pool were obtained using a set of DNA markers analyzed. Analysis of the genetic distances and between population differentiation (FST) showed that the main part of genetic diversity in Maris was determined by the differentiation between the populations of Meadow Maris. The contribution of the differences between the ethnographic groups of Mountain and Meadow Maris to the ethnic gene pool was small. It is suggested that the main role in the formation of the Mari gene pool is played by the geographic factor. 相似文献

Insertion/deletion and VNTR polymorphisms of the serotonin transporter gene were tested for association with schizophrenia in patients varying in ethnicity. A difference in genetic predisposition was observed for continuous and shift-like schizophrenia forms, the former tending to be associated with genotype 12/12 in Tatars and L/L in Russians. 相似文献

The PCR technique was used to analyze the TaqIA- and NcoI-polymorphisms at the dopamine D2 receptor gene (DRD2) in eight populations of the Volga-Ural region belonging to Turkic (Bashkirs, Tatars, and Chuvashes), Finno-Ugric (Maris, Komis, Mordovians, and Udmurts), and Eastern-Slavic (Russians) ethnic groups. Population-specific patterns of the main TaqIA- and NcoI-polymorphisms distribution were established. Specific trends in changes of genotype and allele frequency of the dopamine D2 receptor gene depending on the ethnicity of the population were revealed. 相似文献

The levels of azithromycin in the chorion tissue within the first 3 months of the pregnancy term (42 to 56 days post coitus) were determined. Three days after the use of azithromycin (Sumamed) the antibiotic concentration in the villi tissue was 0.065 to 0.26 mcg/mg (the average of 0.129 mcg/mg). The azithromycin concentration above 0.125 mcg/mg was detected in 38.5% of the women. The results confirmed the fact of significant azithromycin accumulation in the chorion tissue. The percentage of the azithromycin transplacental transfer within the above mentioned pregnancy term varied from 2.3 to 9.3 (the average of 4.6). 相似文献

Evaluations of immune system of 155 patients with rubella and 90 contacts with patients were examined. Detection of viral genetic material in blood, urine, and nasopharyngeal swabs has been performed using RT-PCR method. Clinical diagnosis has been confirmed by RT-PCR in 114 (73.5%) patients. Changes of laboratory tests for rubella without clinical signs of the infection were observed in 20% of contacts. Complex ELISA- and PCR-assisted examination of patients can help to determine the stage of disease and characteristics of immune response. For differential diagnostic of rubella and other infectious diseases with exanthema it is rational to perform complex examination of patients using immunologic and molecular biologic methods. 相似文献
