50 Years of Bong-Han Theory and 10 Years of Primo Vascular System
Figure 3
Images of PNs with different dyes. (a) A PN (BHC) and a PV (BHD) connected to the PN, on the adipose tissue around the rat small intestine. Alcian blue flow through the PVS left it pale blue. Notice that Alcian blue did not remain in the PVS and, therefore, in situ tracking of the PVS using this dye was difficult. (b) A PN and PVs, observed near the rat small intestine, stained with Trypan blue. Notice that the blood vessel and adipose tissue were not stained [39].
