Modern methods of medical rehabilitation in traumatic detachment of retina

Condition was studied of collective specific immunity against diphtheria in vaccinated children who ranged from 2 to 15 years old, living in the industrial region of Pridneprovye, with special reference for the degree of the technogenous environmental pollution. To determine specific cellular sensibilization to diphtherial antigen. LAIT was used for the first time. The studies made showed that in a region under health-hazard conditions lower level of antitoxic antidiphtherial immunity occurs more frequently than in non-polluted areas (twice as much of the values), which fact suggests that technologeous pollution may have a suppressive effect on formation of postvaccinal immunity. Apart from measuring the level of specific antibodies for control of the formation of the immune responsiveness to be monitored you may use LAIT and measure levels of R-proteins.     

The electrical characteristics of the command and motor neurons during the acquisition of a conditioned defensive reflex and the development of long-term sensitization in snails

The mechanisms of conditioning of the defensive pneumostome closure reflex and long-term sensitization were studied at the level of electrical characteristics of the command and motor neurons. A significant decrease in membrane and threshold potentials in the command neurons was observed after the acquisition of the defensive reflex and long-term sensitization. These potentials decreased to a greater extent in the snails subjected to conditioning after the sensitization. Changes in the critical depolarization level for the action potential generation and its amplitude were insignificant. Thus, the observed phenomena testify to an increase in membrane excitability of the command neurons. Similar changes were not found in the motor neurons.     

Traumatic uveitis: the problem of pathogenetic therapy

Inhalative nitric oxide (NO) has recently been included in the therapeutic armament for the treatment of ARDS. We evaluated the effect of inhalative NO on hemodynamic and oxygen transport parameters in 30 internal intensive care patients suffering from ARDS. All patients received a pulmonary artery catheter. Hemodynamics were assessed prior to NO therapy and after 1, 6, 12, and 24 h. 80% (n = 24) of the patients were classified as therapy responders. The median NO dose was 15 ppm (range 5 to 40 ppm). The PaO2/FiO2--ratio increased significantly after initiation of NO (p = 0.0002) while the pulmonary shunt fraction (Qs/Qt) decreased significantly (p = 0.0019). All other measured or calculated parameters including arterial and pulmonary arterial blood pressure remained unchanged. No negative effects of the therapy could be observed. Inhalative NO improves oxygenation in most intensive care patients with ARDS and thus offers the possibility to reduce invasiveness of mechanical ventilation.     

Physico-chemical properties of pulmonary surfactant after gastrectomy and cholecystectomy

A group of zinc-binding cDNA clones from a human fetal heart library was isolated using an oligonucleotide probe to the consensus sequence of the linker region of zinc finger proteins. Genes for novel clones were mapped by fluorescence in situ hybridization. In the process, we identified a previously unrecognized locus for two zinc finger-coding genes in human chromosome 19q13.1-q13.3 (ZNF180,ZNF181), where genomic rearrangements were shown to be accompanied by various developmental abnormalities, DNA repair deficiencies, and cellular malignancies.     

The influence of antioxidants on morphological structure of internal organs of rats in acute hypoxia

The results of pathomorphological research of internal organs of rats in hypoxical hypoxia and in the action of the antioxidant dihydroguersitine in acute hypoxia. Lt shows that DHQ causes favourable morphological changes in internal organs in acute hypoxia.
