Umstimmung als Behandlungsweg.

This title, which literally means "change of tone or pitch as therapeutic method," might be more freely translated as "alterative therapy." The book is a symposium chiefly on "nonspecific cell activation" by numerous prominent German students of the subject, each of whom reports the degree to which these newer methods have been found helpful in his particular field. It is led by Wolfgang Weichardt, who takes a wide view of "Umstimmungs-therapy," including in it not only sensitization but also desensitization, used, for example, in allergic conditions. He shows by experimental muscle curves how minute amounts of protein destruction products as well as colloidal metals may markedly increase the activity of cells. He also shows that pathogenic micro-organisms may be activated in their growth by similar means. In infectious diseases, therefore, the problem of nonspecific immunization is to stimulate to the highest possible degree the defensive processes without activating the growth
