In Vivo Visualization of the Pericardium Meridian with Fluorescent Dyes

Figure 2

Variations in fluorescein migratory paths. Examples are provided to reveal variations in dye migrations. (a, b) Fluorescent signals were strong and quickly formed linear trajectories. Additional collateral lines were observed accompanying the main meridian-associated line. (c, d) Intermittent, broken lines formed along PC meridian within 30 minutes after injection. (e) Dye was also visualized in blood vessels. (f) Linear paths formed slowly 1 hour after injection and was weakly visible; nevertheless, PC3 appeared approximately 40 minutes before the linear path could be visualized. Similarly, in other cases, only PC3 fluoresced, while no linear path was observed (not included here). (g, h) No linear trajectories or point fluorescence at PC3 was seen.
