CYTOCHEMICAL 



AND CYTOPHYSIOLOGICAL PECULIARITIES 



OF NERVE TISSUE 



BIOLOGICAL ORGANISATION 



A. L. SCHABADASCH 



There is no doubt about nerve cell functional asymmetry, although its 

 morphological substrate bas little been found out. In a number of histo- 

 chemical indicators we bave managed to clear up important physico 

 -cbemical peculiarities of proteins and nucleoproteins in différent parts 

 of a neuron and its organoids. This brings us nearer to tbe study of the 

 biological basis of a nerve cell spacial polarisation. We bave observed 

 clear eut différences in isoelectrical points (i.e.p.), typical for definite 

 structures: mitochondria, tigroid cluraps, cytoplasm, axoplasm and synaptic 

 terminais in the nervous system at relative rest — in particular. At exci- 

 tation, narcosis or inhibition processes, tbe i.e.p. displaceraents are 

 observed, alterating normal rations (depending on the functional state) 

 both to the side of deepening différences and to the side of their levelling. 

 In the main, physiologically moderate function is histochemicaliy 

 reflected only through the changes of physico-chemical characteristics 

 and inter-relationships of the system components. I.e.p. gradient of 

 a neuron structures is an important factor of morphogenesis and biological 

 properties of the nerve tissue.
