Effect of 1(4-amino-2-methyl-5-pyrimidinyl) methyl-3-(2-chloroethyl)-3-nitrosourea hydrochloride (ACNU) on Sato lung carcinoma (SLC). Preliminary result of immunochemotherapy for SLC by combination of ACNU and Propionibacterium acnes

Abstract

ACNU was highly effective for Sato lung carcinoma transplanted intravenously or intramuscularly by using a large single dose, and the cytotoxic action of ACNU for SLC showed clear dependence upon tumor size. Nonspecific activation of host-defence mechanism by Propionibacterium acnes contributed to the suppression for the regrowth of solid SLC treated by ACNU.
