The blockade of the reinforcing effects of angiotensin-II on hemodynamic parameters in rats with experimental diabetes mellitus
Serova O.N., Kalashnikova E.Y., Elfimov A.I., Lagutina L.V., Torshin V.I.

Abstract

Diabetes mellitus (DM) causes not only carbohydrate metabolism, but and disorders of the cardiovascular system, resulting in developing hypertension. It is known that in the regulation of hemodynamics the renin-angiotensin system plays an important role, the effector peptide of which is angiotensin II (A-II) causes hypertension and increases the heart rate (HR). In this work we studied the change in systolic blood pressure (SBP) and HR under the action of A-II in rats with experimental autoimmune type 1 DM. Autoimmune diabetes in Wistar rats was induced by injections of streptozotocin. Two weeks after the third injection, SBP and HR were measured in animals. The day before the start of the experiment the blood glucose level was detected. The results showed the absence of hypertensive properties of A-II and its reinforcing effect on HR in rats with autoimmune diabetes, indicating diabetic hyperglycemia as the main factor in the ineffectiveness of the action of A-II on hemodynamic parameters. It can be assumed that the significant increase of blood glucose level in condition of autoimmune diabetes type 1 DM occurs specific desensitization of receptors to A-II in the central and peripheral structures governing the SPB and HR, i.e., the blockade of the physiological action of this peptide.

Grinberg M.V., Harchenko N.V., Kunda M.A., Zapirov M.M., Rozhkova N.I.

Abstract

Purpose . To compare the diagnostic performance of digital breast tomosynthesis (DBT) and digital mammography (DM) for breast cancers. Materials and Methods . The study included fifty-seven patients with histologically verified breast cancer. Given the subjective evaluation of the benefits of technology for tomosynthesis imaging of pathological signs characteristic of breast cancer (tumour, focal asymmetry, restructuring or microcalcifications). The data obtained on the base of DM and additional DBT information were assessed according to BI-RADS scale (force BI-RADS). The interdependence between the categories according to BI-RADS scale and the nature of the radiological manifestations of breast cancer was determined using Chi-square (c 2) test. Results . A total of 59 breast cancers were reviewed, including 17 (28.8%) mass lesions, 12 (20.3%) focal asymmetry/density, 6 (10.2%) restructuring, 23 (39.0%) calcifications, and 1 (1.7%) intracystic tumor. Mammography with DBT was more informative to visualize 58.8% of the lesions, 83,3% of focal asymmetry, 94.4% of violations architectonics and only 11.6% of the signs of microcalcifications. When making conclusion on BI-RADS scale, in 84.4% of cases category of findings was increased from 0 (when performing DM) to 4 or 5 (when performing DBT). Category opinions 4A on the scale of BI-RADS in the implementation of DM in 27.3% of cases was increased after evaluation of the images of the DBT, a symptom of malignancy in this category were mainly detected microcalcifications. Significant interdependence ( p < 0,001) between BI-RADS category and pathological radiographic signs was noted. Conclusion . DBT allows to obtain more accurate visual information about mass formation, focal asymmetry, violation of the architectonics and improves the diagnostic efficacy of mammography.

Kostin A.A., Andriukhin M.I., Babichenko I.I., Pul’bere S.A., Motin P.I., Tal’berg P.I.

Abstract

Iimmunohistochemical study of localization of matrix metalloproteinase-9 and inhibitor of matrix metalloproteinase-1 and cells proliferative activity by Ki-67 protein has been carried out in benign prostatic hyperplasia (BPH) and adenocarcinoma (AC) of different grades by the Gleason score. A moderate positive correlation between the Gleason score and cell proliferation Ki-67 index ( rs = 0,674) and a moderate negative correlation with the level of such score and expression of matrix metalloproteinase-9 ( rs = -0,660) were detected. A weak significant negative correlation exists also between the level of proliferative activity of secretory cells and the expression of MMP-9 by tumor cell ( rs = -0,369). A significant decrease of the MMP-9 and TIMP-1 levels in the AC of different gradations have been found. The invasive properties of tumor cells, which are expressed in the destruction of collagen IV of basement membrane and connective tissue stroma of the prostate, associated with an imbalance between MMP-9 and protein blocking this enzyme - TIMP-1, expression of which decreases in AC compared to BPH.

Complex diagnosis of parietal formations of the thoracic cavity
Glagolev N.A.

Abstract

The work is devoted to computed tomography (CT) and ultrasound (US) diagnosis of the thoracic cavity diseases, which highlights many of the issues in the literature clearly or not covered at all. Advances in the CT and US technologies have demanded reconsideration of the scientific data about value of these methods in diagnostics of diseases of lungs and pleurae. Now US is widely used in the diagnosis of diseases of the organs and tissues of the abdominal cavity, retroperitoneal space, pelvic organs, cardiovascular system and is insufficiently used for the study of pathological changes of lungs and pleura. The analysis of possibilities of US and CT in diagnosis of parietal thoracic cavity formations and indications for ultrasound are presented, the US technique as well as US semiotics of revealed pathological changes are described. Implementation into clinical practice of modern methods of diagnosis increases the chance of early detection of the disease when it is still possible to use the radical methods of treatment
