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.
采用改良的法尔克法，在健康大鼠及长期给予胍乙啶的大鼠中，测量其心房中小而强荧光（SIF）细胞的荧光强度。单个SIF细胞的正常荧光值低于成簇SIF细胞的荧光值。然而，在化学性交感神经切除术后，两种类型的SIF细胞均出现了类似的偏差。在实验的6 - 9周期间，荧光平均值下降，在接下来的3周内升高。上腔静脉和房间隔中的SIF细胞表现出最明显的反应。
