Function of the umbilical cord and amnion. Runge (Zentr. f. G., 1927, No. 1)
The function of the umbilical cord and amnion was studied by Runge by pouring Ringer's solution with Al'ethylenblau, Patentblau, Trypanblau and Kongoroth dyes at 3 centigrade of mercury into the umbilical vessels. It turned out that Trypanblau and Kongoroth did not diffuse through the vein walls, while the blue easily stained the entire tubule. Arterial walls were impenetrable for all dyes.
