[Demonstration of the noradrenaline-and adrenaline-secreting cells of the adrenal medulla in laboratory animals and man].

A comparative study of four histochemical methods of estimation of noradrenaline- and adrenaline-secreting cells in the adrenal medulla of laboratory animals and man was carried out at different terms after death and depending on the temperature of tissue storage before their histochemical treatment. It was stated that light histochemical method of Honoré and luminescent method of El-Badawi and Schenk are highly specific and make it possible to estimate the amount and location of catecholamines in the adrenal medulla of man and animals. The advantage of honorés method is that it allows to differentiate, at light level, noradrenaline-secreting cells from adrenaline-secreting ones and consider their structural peculiarities. /ence, this method can be recommended for differential study of catecholamines in the adrenal medulla of laboratory animals and man.
