Abstract
1) Nucleotid in cat's blood cells is adenine-nucleotid, but it is transformed into inosine-nucleotid when it is released from blood cells upon intravenous injection of colloid. The deamination is performed either in the blood immediately after releasing, or in some organs, e.g. in liver, on circulation. This is the reason why we could not find adenine-nucleotid in the plasma even during colloid shock. 2) Ultraviolet absorption curve of the active principle which appeared in the plasma on recovering from colloid shock corresponded with that of epinephrine. This suggests that the rise in blood pressure which appears on recovering from colloid shock is due to the excretion of epinephrine.
