title: [Experimental study of the myelotoxic effect of tomizine].
abstract: In tests conducted on 220 rats with transplantable sarcoma M-1 and intact animals acute toxicity, antineoplastic effect and the action on the blood system of tomizine, a new neoplastic drug of the group of the folic acid antagonists, were studied. Investigation involved a single intraperitoneal injection of the drug in DL50/30 and MTD. The compound is shown to exert an inhibiting action on the development of sarcoma M-1 and lengthens the survival of the tumour-stricken animals, without producing any pronounced myelotoxic effect. The disclosed shifts on the level of the periphedal blood and marrow were short-lived and concerned mainly the erythroid germ cells.
