Plasticity of the Muscles in the Protein Sensitization. Involvement of Cholinergic asnd Purinergic Mechanisms

Abstract

The authors investigated the involvement of the adenosine triphosphate (ATF) in the mechanisms of plasticity in the striated muscle in condition of protein sensitization. Contractile function and non-quantum secretion of the acetylcholine in the endplate zone were studied in isolated skeletal muscles of mouse legs (musculus soleus and musculus extensor digitorum longus) and strips musculus diaphragm. The authors studied the soleus and diaphragm dynamics of the force vector of muscle contraction after effects of exogenous adenosine triphosphate correlated with changes non-quantum secretion of acetylcholine in all the experimental models. However, the extent of these changes in sensitized animals is less pronounced than in the controls. It is suggested that adenosine is a party change mechanisms and functional properties soleus and diaphragm at the protein sensitization. The basis of the development of resistance, stability to long as the external stress, and at the initial stages of the experimental allergic these muscles are dependent adenosine mechanisms regulating their sensitivity to acetylcholine. These processes provide a reduction in respiratory muscle fatigue in hypoxia that occurs in asthma, chronic obstructive pulmonary disease and broncho-spastic syndrome, as well in increase their performance during prolonged physical activity. The reasons for changes in the force reduction extensor digitorum longus at a protein sensitization doesn’t associated with the mechanisms of muscle excitation mediated by adenosine triphosphate.

Investigation of the relationship between temperament and eating behavior among adult health school students

“…Темперамент (от лат. temperamentut -надлежащее соотношение частей, соразмерность) -это характерная для данного человека совокупность относительно устойчивых психических особенностей, связанных с эмоциональной возбудимостью (быстрота возникновения чувств и их сила) и определяющих динамику (ритм, продолжительность, интенсивность) протекания его психических процессов и поведения [3]. Темперамент отражает аспекты поведения преимущественно врожденного характера, поэтому свойства темперамента наиболее устойчивы и постоянны по сравнению с другими психическими особенностями человека.…”
