[Cytofluorimetric study of the small, intensely fluorescent cells of the rat atria in pharmacological sympathectomy].
The fluorescence intensity of small intensely fluorescent (SIF) cells of rat atria was measured by the modified Falck method in health and chronic guanethidine administration. The normal value of fluorescence of single SIF cells was lower than that of clustered SIF cells. However, similar deviations were observed for both the types of SIF cells under chemical sympathectomy. The mean value of fluorescence decreased during 6-9 weeks of the experiment and increased during the next 3 weeks. The most pronounced reaction was exhibited by SIF cells in the superior vena cava and interatrial septum.
