high incidence of cerebral stroke (CS) determines the great social importance of this problem [1–5]. More than five million people die every year from CS; in most countries, stroke is the second or third most common cause of death [6]. CS has an important role as a cause of population disability – less than 20% of people who have had CS are able to return(More)
Inhibition of the soleus H-reflex was studied in hemiparetic postapoplectic patients and in control group of patients without motor disorders. The depression of H-reflex was caused by stimulation of ipsilateral peroneal nerve and presented in two successive waves (D1 and D2). The former of them corresponds to presynaptic inhibition. The size of both waves(More)
Three forms of adenylate cyclase have been detected in Y. pestis: membrane-bound, cytoplasmic and extracellular. Extracellular adenylate cyclase has been purified so as to achieve a homogeneous state, and some of its physicochemical parameters have been investigated. In the process of purification the initial preparation of this enzyme has been subjected to(More)
The effect of purified preparation of adenylate cyclase isolated from Y. pestis on peritoneal leukocytes of white mice and guinea pigs was investigated. Y. pestis adenylate cyclase was shown to accomplish its pathogenic action via histamine-specific receptors on the surface of eukaryotic cells. The involvement of H1 and H2 histamine receptors on target(More)
The biological action of Y. pestis adenylate cyclase on peritoneal leukocytes of guinea pigs has been studied by means of chemiluminescence. Y. pestis adenylate cyclase is supposed to contribute to the "oxidation" explosion of phagocytes in plague.
A new classification of motor disorders in patients after brain hemisphere's stroke as well as with its sequelae was proposed on the basis of clinical electromyographic studies. The classification validity was confirmed by mathematic statistic methods. The classification was composed of motor syndromes and is based on the following criteria: the severity of(More)
Y. pestis extracellular adenylate cyclase suppresses the oxidation metabolism of peritoneal leukocytes in white mice. The character of the modulating action of the enzyme in its interaction with the target cell infers the participation of adrenergic receptors.
