VAGAL MOTOR RESPONCES OF GASTROINTESTINAL TRACT ENHANCED BY THE SEROTONINOREACTIVE STRUCTURES
The mechanical activity of the stomach, duodenum and ascending colon were recorded in acute experiments in 29 rabbits. The distal part of the vagus nerve was electrically stimulated in intact animals and on the serotonin adipate background. It was shown that serotonin enhances motor vagal reactions, increasing both intensity and in some cases the duration. Concluded that between serotoninergic structures that regulate the motility of the gastrointestinal tract and parasympathetic portion of the autonomic nervous systemthe functional interaction exists.
Key words: serotoninergic structures, stomach, duodenum, ascending colon, the vagus nerve.

CHANGE MECHANISM OF CONTRACTILE FUNCTION OF STRIATED MUSCLE MOUSE IN VITRO BY PROTEIN SENSITIZATION. INVOLVEMENT OF ATP
We investigated the involvement of ATP in the mechanism of the effect of protein sensitization (PS) on contractile function and non-quantum secretion of acetylcholine in the area of end-plate (H-effect) of isolated skeletal muscles of leg (m.soleus and m. extensor digitorum longus (m.EDL)) and stripes m . diaphragma mouse. In m.soleus and m.diaphragma dynamics of the force vector of muscle contraction is correlated with changes in the H-effect in all the studied experimental models. However, the extent of these changes in sensitized animals is less pronounced. It has been suggested that ATP is a party change in the mechanisms of functional properties m.soleus and m.diaphragma in PS and reflects the development of resistance mechanisms in these muscles to external loads. The reasons for the changes in contraction force m.EDL PS not related to ATP-mediated excitation mechanism of the muscle.
Key words: contractile properties, nonquantum secretion of acetylcholine, m.diaphragma, m.soleus, m.extensor digitorum longus, mouse, protein sensitization, ATP.
