Abstract
Competitive IM-PH immunoadsorption of drugs and immune reactant has been investigated in order to perform better immunoadsorption and medication. IM-PH has a stronger affinity for immune complex (IC) than cortisol and no affinity for antibiotics. However, activated charcoal adsorbed them all when they were given within a therapeutic dose. These experimental results may be a useful guide for hemoperfusion and plasma perfusion.
