Effects of new wound dressings on healing of thermal burns of the skin in acute radiation disease.

Effects of new wound dressing bacterial cellulose impregnated with SOD and poviargol (Procel-Super and Procel-PA) and Inerpan hydrogel dressing on the reparative processes in deep dermal burns (IIIa-IIIb degree) in rats exposed to total even irradiation in a dose of 4 Gy were studied. Inerpan and Procel-Super dressings proved to be the most effective under these conditions: they accelerated healing of burn wounds by 17.0 and 5.

[Structural basis for the regulation of the neuronal sensitivity].

Using light and electron microscopy structural bases for intracellular, extracellular and integrative regulation of synaptic efficiency and neuron sensitivity were established in rat sensomotor cortex. Intracellular regulation is realized basically through modulation of postsynaptic components of the synapse, while extracellular one is provided by synaptic endings of "recurrent" axons on GABA-ergic relay and interneurons. Integrative regulation is realized by means of concentration of similar axonal terminals in restricted cortical area and arrangement of "neuromediatory" pool.

[The morphological characteristics of cell death in different forms of acute tick-borne encephalitis].

The study was aimed to identify different types of cell death in monkey brain in flavivirus experimental encephalitis. 10 brain areas most vulnerable ("indicator") of the disease in its different forms (symptomless, intermediate and severe) were examined in animals infected intracerebrally with viruses of tick-borne encephalitis. Cells of ectodermal and mesenchymal origin displayed apoptosis that was most pronounced in intermediate form of the severity of the disease.
