Abstract
In ten consecutive cases of typical scarlatina admitted to our Department, yakriton was used per recti or subcutaneously. Though the number of units of the hormone was very different in each case, all the 10 cases did not develop nephritis. No other special method which had been reported to be effectual for the prevention of scarlatinal nephritis was used at all. It is probable that yakriton will counteract the development of nephritis in scarlatinal cases.
