The analysis of the data available in the literature has shown that bipolar pacing systems are promising. The paper indicates that the first samples of a Soviet bipolar electrode have been made and tested in the laboratory setting. It also raises whether it is necessary to design bipolar pacemakers. 相似文献

The efficacy of nitrosorbide, corinfar and obsidan in preventing myocardial ischemia, induced by exercise or intravenous dipyridamole, was evaluated in 20 coronary patients. Nitrosorbide was found to be the most effective, and obsidan, the least effective, drug in preventing the steal syndrome. It is suggested that the efficiency of anti-anginal drugs is based on their effect on coronary flow control as well as hemodynamic determinants of myocardial oxygen requirements. The dipyridamole test can be used for the assessment of the effects of antianginal agents. 相似文献

Under study was the functional state of the sympathoadrenal system and correlation between its activity and the white blood parameters in 30 patients with ulcer disease of the stomach and duodenum complicated by ulcer perforation, bleeding, peritonitis in the postoperative period. It was found that the complicated ulcer disease was accompanied by an increased functional activity of the sympathoadrenal system which was most pronounced in perforation. 相似文献

Echobiometry of 24 eyes operated on for congenital cataracts has been carried out. The infants' ages varied from 4 to 6 months. 23 children (43 eyes) have made up the peference group. The measurements have been carried out in 6-7, 10-12, and 24-26 months after surgery. The results evidence no relationship between early cataract extraction and the growth of the anteroposterion axis of the eye in infants. 相似文献

Surgery remains the treatment of choice for massive and recurrent hemoptysis. In some instances, however, immediate surgical intervention is contraindicated. In these situations, bronchial artery embolization (BAE) has proved to be a successful definitive treatment for non-surgical candidates and a palliative therapy in patients requiring hemodynamic stabilization prior to surgery. The most serious complication of BAE is spinal cord ischemia. This relates directly to the potential anastomotic connections between the bronchial circulation and the anterior spinal artery. Somatosensory evoked potentials (SSEPs) have been used in the past to monitor spinal cord ischemia during procedures that threaten the vascularity of the spinal cord. The authors report two cases in which SSEPs were employed to monitor spinal cord ischemia during bronchial artery embolization. 相似文献

With due respect to their many-year experience, the authors focused their attention on the peculiarities of implementation and registration aspects of the immunofluorescence method of immunotyping made in cell suspensions and in tissue imprints; additionally they made a system of a set of monoclonal antibodies (used for the purpose), which enable the differential diagnosis of reactive conditions related with various malignant lymphoproliferative diseases (LPD). It order to specify a nature of lymphoid cells it is suggested to undertake the immunophenotyping withing a gradually expanding set of monoclonal antibodies, which reflects different parameters of lymphoid cells like linear attributes, clonal characteristics, differential-diagnostic markers, functional status and proliferative activity. Typical marker phenotypes of lymphoid cells observed in the main B- and T-cell LPDs are described; a possibility is mentioned that there can be errors in interpreting the phenotyping results while diagnosing an LPD. 相似文献
