The frequency of the polymorphic variant T196C (Leu33Pro, rs5918) of ITGB3 gene was studied in several groups of inhabitants of Siberia, including women with reproductive disorders (n = 186), patients with acute coronary syndrome (n = 330), and population control (n = 858). The frequency of the rare PLA2 allele among residents of Tomsk and Kemerovo was 14.7% and 15.0% respectively. There were no differences in the allele and genotype frequencies of polymorphic variant between patients with acute coronary syndrome and the control group (p = 0.925, p = 0.622). The highest frequency of abnormal PLA2 allele (22.1%) and the PLA2/PLA2 genotype (8.8%) was observed among women who had miscarried, which was significantly different from the frequency of this allele and genotype in the control group (14.7%, p = 0.017; 2.1%, p = 0.0009). Sequencing showed that all samples with the nonspecific band had the polymorphic rs5918 variant and rs36080296 mutations (T216G, Leu66Arg). The frequency of the rs36080296 mutation among the residents of Siberia was 0.51%. Among the women with reproductive disorders, the frequency of rs36080296 was 2.7%, while in the group who suffered from miscarriages, it was 4.4%; this was different from the frequency in the control group (0.08%, p = 0.2 × 10?6). The accumulation of mutations was also observed among men with acute coronary syndrome (0.6%), but the differences from the control group (0%) had no statistical significance. Thus, the rs36080296 mutation may be a factor in predisposition to miscarriage, especially in combination with the PLAII allele. In addition, the rs36080296 variant among men may be associated with acute cor onary syndrome, which requires further study. 相似文献

Using the model of experimental colibacillosis in mice morphological, immunomorphological and morphometrical studies of duodenum 1 to 24 hours after inoculation were performed. Typical dynamics of cellular composition in the intestinal wall, accompanied with increased lymphoplasmacellular infiltration, and dystrophic changes in cells of submucosal and intermuscular neuroplexuses were found. The data obtained testify, that the infectious process at the acute state of experimental colibacillosis has an immune character (immediate hypersensitivity of local type), characterised by increasing in immunoglobulin-containing cells and including in this process of mast and endocrine cells. 相似文献

Four fractions of IgG antibodies to native DNA (nDNA) were obtained from blood of patients with systemic lupus erythematosus (SLE). These antibodies displayed a thermostable DNA-hydrolyzing activity and were different in affinity for DNA-cellulose and sorption on DEAE-cellulose. DNA-hydrolyzing antibodies to nDNA are metal-dependent endonucleases, cause mainly single-strand breaks in DNA, and are active over a wide range of pH. By atomic-force microscopy, three-dimensional images of DNA complexes with DNA-hydrolyzing antibodies to nDNA were obtained with nanometer resolution, and a nonprocessive action mechanism was shown for the DNase activity of antibodies to nDNA. 相似文献

The influence of cross-linked by dimethylsuberimidate dimeric RNAse from Bacillus intermedius on peritoneal rat macrophages has been investigated in vitro. It has been shown that dimeric RNase with concentrations of 0.5-40.0 mg/ml decreases the functional activities of macrophages. This is manifested in the inhibition of the phagocyte function of macrophages and suppression of the fusion of phagosomes with lysosomes. The change in the cytoplasmatic membrane surface structure induced by the dimers, which is stronger than that induced by monomers, has been demonstrated using atomic force microscopy. The role of membrane properties modification in the inhibition effect of RNase dimers on the functional activities of macrophages is discussed. 相似文献

Ultrastructural changes of duodenal epitheliocytes were studied at the period from 15 minutes to 24 hours after inoculation using the model of experimental esherichiosis. The results obtained allow to determine the succession of ultrastructural changes and dynamics of adenylate cyclase activity of epithelial cells, involvement of endocrine cells in the pathological process. Combination of the certain morphological and cytochemical reactions and their dynamics allowed to make conclusions about typical ultrastructural changes in epitheliocytes at the early stages of experimental esherichiosis. 相似文献

The functional state of cell-mediated and humoral antiendotoxin factors in patients with chronic viral hepatitides B and C has been studied. A decreased content of antibodies to glycolipid of chemotype Re and to Escherichia coli O14 with common enterobacterial antigen was shown to occur in these diseases. In addition, a decreased number of neutrophils, eosinophils and thrombocytes has been noted. The conclusion has been made that patients with chronic hepatitides are not protected from the pathogenic action of endotoxin penetrating from the intestines into the systemic blood stream. 相似文献

The activity of succinic dehydrogenase, myosin ATPase, as well as lactic dehydrogenase (LDG) spectrum and cross-section area of different type of muscle fibers have been studied for 3 weeks after denervation (control) and after denervation and intraperitoneal injection of 10(-6) M FeCl3. Intraperitoneal injection of FeCl3 prevented the development of denervation phenomena (increase in cross-section area of muscle fibers, changes in LDG spectrum). 相似文献

In chronic viral hepatitis B and C the development of intestinal dysbacteriosis and high occurrence of concomitant diseases of the gastrointestinal tract were observed. In cases of increased dysbacteriosis degree and in the presence of concomitant diseases the blood plasma of patients exhibited higher activity in reaction with the of amebocytes lysate obtained from crabs of the genus Limulus. A suggestion was made that the endotoxin of Gram negative intestinal microflora could probably play some role in the development of pathological processes in chronic viral hepatitis B and C. 相似文献
