Histochemical investigations of thyrosine in normal and pathological glia cells.
Investigations on thyrosine content in normal and pathological glia cells are the continuation of researches on occurrence of protein functional groups in abnormal glia cells (Szydlowska, 1970a, 1970b). The investigations carried out with the use of Caselli, Glenner and Lille methods have shown that fluctuations of thyrosine level in nuclea and cytoplasm of glia cells pathologically changed correspond to quantitative changes of other functional groups of proteins. Hence it may be assumed that the observed increase of thyrosine in pathologically changed glia cells is not connected with the change of protein composition of a cell but with the general increase of proteins in its nucleus or cytoplasm.
