RESUMO
1- Acidomycin, a new antibiotic prepared in the Takata Laboratory, has been employed in the treatment of leprosy. 2- In this experiment the antibiotic was injected superficially into the leprous skin lesions, because when injected subcutaneously or intravenously acidomycin has shown no therapeutic effect in either tuberculosis or leprosy, although it is very active against the tubercle bacillus in vitro. 3- With intracutaneous application, on the contrary, there has been demonstrated a very interesting action. Where it was effective there was fading or disappearance of the macules and improvement or recovery of sensitivity. In certain cases there was decrease or disappearance of bacilli in the faded macules. 4- In several cases, lesions at a distance from those that were injected also showed improvement. In one of them a nodular auricularis magnus nerve became much reduced.
