[THE THROMBUS FORMATION IN THE PROSTHESIS AS A REACTION OF ORGANISM ON ITS MATERIAL].

Abstract Vascular prostheses, excised because of their functional properties loss, were studied. Using different methods there was established, that this complication is caused by the thrombus formation as a reaction of organism on the prosthesis material. The testing procedure on compatibility was proposed, using atomic-power microscope.

[Neuronal impulse activity in surviving sections of the guinea pig neocortex during blockade of synaptic transmission by adenosine].

Background neuronal discharges were recorded extracellularly in guinea pig cerebral cortex slices maintained in vitro. Synaptic disconnection was reached by adding 100 microM of adenosine or 20-75 microM of 5-AMP. It was shown that 30-40% of neurons continued to discharge even under conditions of complete synaptic blockade, although the discharge frequency decreased.
