In vitro tests of antibacterial actions of sulfanilamides, behavior of bacteria against antagonists of sulfanilamides, and the adsorbability on charcoal powder were experimented. As a result, it seems probable to assume that the antibacterial power was increased by the strengthening of adsorbability resulting from bonding of heterocyclic radical to sulfanilamide.
