In the cat synapses between vesicle containing profiles were observed in ventral and dorsolateral pontine nuclei. The presynaptic elements consisted of two types of axon terminals: axon terminals characterized by a population of small (38-40 nm) round synaptic vesicles (SSV) and axon terminals containing pleomorphic synaptic vesicles (PSV). The postsynaptic pale elements (PP) had pleomorphic vesicles and some features attributed to dendrites. In the dorsolateral pontine nucleus most of PP profiles took part in serial synapses, usually as an intermediate component, they were rarely observed in triads. On the basis of their electron microscopical appearance and synaptic relations they might be considered to represent a dendritic part of putative interneurons. 相似文献

Diagnostic validity of the criteria of myocardial ischemia in coronary patients exposed to the treadmill test is assessed. The risk of a false diagnosis of coronary insufficiency on the basis of the pain syndrome was 5 times as high as that of diagnosis based on ischemic electrocardiographic ST depression. In subjective assessment of walking tolerance, patients with severe angina were particularly prone to mistakes. Limitations of angina classifications by severity, based on subjective sensations of coronary patients, are considered. 相似文献

Based on the experience with treatment of 26 patients the authors recommend to use mainly conservative treatment with the intrapleural administration of fibrinolytic drugs. The method was used in 20 patients. All of them recovered. 相似文献

Methods of endoscopic papillosphincterotomy and endoscopic papillosphincterowirsungotomy are presented. The effectiveness of the treatment was 96%. Operative procedures on emergency made up 1%, lethality-1%, complications-3% of the cases. 相似文献

A method of diagnostics and assessment of the severity of arterial insufficiency of lower extremities was developed on the basis of multistep treadmill-test and measuring time of reestablishment of continuous bloodflow in the popliteal artery by the method of ultrasonic doppler flowmetry. An examination of 40 patients with angiographically detected alterations of the vessels and 18 healthy persons was performed. It was found that the diagnostic and assessment criterion of arterial insufficiency in treadmill-test with high parameters of sensitivity and specificity is longer duration of the period of reestablishment of continuous bloodflow over 180 sec. The arterial insufficiency severity is estimated by the value of exercise by the moment of the appearance of the criterion. 相似文献

Materials are presented on six cases of fatal acute radiation disease consequent to relatively proportional beta- and gamma-irradiation after accident in the nuclear submarine. The comparison is performed of this material with the data published on the radiation sequelae of the Chernobyl nuclear catastrophe. 相似文献
