Anemia-inducing substances have been prepared from gastric juice (K-7 and K-8) of patients with gastric cancer, cancerous gastric tissue (MK-62 and MK-63) and human placenta (P-62) by means of ethanol or acetone fractionation, and the effect of these substances on the osmotic fragility of rabbit red cells in vitro was studied.
These substances, which are mucoproteins, decreased the osmotic resistance of the rabbit red blood cells in vitro.
