Retardation of Growth of Walker Rat Carcinoma 256 by Administration of Diethyl Riboflavin. ∗

Abstract

Summary

1. Rats with Walker Carcinoma 256 transplants showed an 8 g greater retention of their carcass tissue when receiving diethyl riboflavin than pair fed controls receiving an equimolar amount of riboflavin. 2. The average tumor size, expressed as per cent total body weight, of the diethyl riboflavin group was 20% while the average tumor size of the riboflavin group was 30%. This indicates a 33% inhibition of the growth of the tumors due to the administration of diethyl riboflavin.
