Clinico-morphological changes in a burn wound after electric stimulation with pulsatile current

The healing of sluggishly postburn wounds after local electrostimulation (ES) with the use of current-conducting carbon tissue as the electrode was studied in 12 patients. Analysis of the clinical data which were corroborated by the results of morphological and biochemical studies confirmed the marked stimulating effect of local ES which facilitates successful taking of dermal autografts and healing of burn wounds. The obtained data are evidence that the method of ES through a current-conducting carbon tissue is promising in the complex of measures for local treatment of burn wounds.     

Functional properties of thrombocytes and inhibitors of proteolytic enzymes of the blood in patients with acute forms of ischemic heart disease

Blood platelet activity and levels of proteinase inhibitors and proteolytic components were assessed in patients with progressive angina of effort, spontaneous angina and acute myocardial infarction. alpha 1-antitrypsin and alpha 2-macroglobulin were shown to be involved in fibrinolysis regulation and kininogenesis. In acute myocardial infarction, there was a close inverse correlation between platelet release and blood kallikrein levels.     

The properties of monoclonal antibodies to HIV gag gene proteins]

Immunization of BALB/c mice with natural purified HIV antigen, fusion of spleen cells with myeloma cells and subsequent selection of hybrid clones using recombinant gag antigen of HIV gave hybridomas producing monoclonal antibodies (MCA) to HIV. The immune blotting method demonstrated that 3 clones interacted with protein p24 and 4 clones with protein p17 of HIV. Competitive EIA led to a conclusion that the resulting MCA detected at least 3 antigenic determinants in proteins, products of gag gene of HIV. The potentials of using these MCA for the detection of viral antigen in HIV-infected continuous cell lines were demonstrated.     

Effect of olanzapine treatment on platelet glutamine synthetase-like protein and glutamate dehydrogenase immunoreactivity in schizophrenia.

According to contemporary views, the glutamatergic system is implicated in the pathogenesis of schizophrenia, and atypical neuroleptics exert their effects (at least partially) through the glutamatergic system. Immunoreactive glutamate-metabolising enzymes, such as glutamine synthetase-like protein (GSLP) and two glutamate dehydrogenase isoenzymes (GDH), have been discovered in human platelets. The amount of GSLP in the platelets of 40 chronic patients with schizophrenia was found to be significantly higher than in 33 controls (consistent with our previous finding of increased amounts of GSLP in the prefrontal cortex of chronic schizophrenia patients). Moreover, survival analysis of the group of patients treated with olanzapine for 28 weeks showed that the larger amount of GSLP measured in platelets before treatment, the shorter the treatment time needed to achieve a positive clinical response (defined a priori as > or = 20% reduction in PANSS total score from the initial level before the treatment). Hence, GSLP level may serve as a predictor of the treatment duration to achieve a positive outcome with olanzapine. Both GSLP and GDH were found significantly changed in the course of treatment; hence, treatment with olanzapine influences the amounts of glutamate-metabolising enzymes in the platelets of chronic schizophrenia patients.     

Pulmonary aspergillosis and its treatment

The authors had 85 patients with various forms of bronchopulmonary aspergillosis under observation; 45 of them were treated by various types of operative interventions. Forty patients were given mycostats. The article describes the indications and contraindications for surgical treatment, the volume of the operative interventions, the postoperative complications and their management.
