[E1On the effect of 6-methyluracil on mice damaged by 2,4,6-triethylene-imino-1,3,5-triazine or by X-irradiation (author's transl)].

Survival time of mice after i.v. injections of 2,4.6-triethylene-imino-1,3,5-trazine (TEM) or total body-X-irradiation (TBI) was increased by 6-methyluraclil (6-MU) when given in food (200 ppm). Under the same conditions, 6-MU decreased the involution of spleen and thymus (as measured by DNA-content and DNase II activity) under the infuence of TEM and enhanced the regeneration of the spleen after TBI. Elevation of DNase I- and protein content of the kidneys and a (short-dated) increase of incorporation of 14C-phenylalamine into microsomes of liver of 14C-orotic acid into RNA of liver and kidney suggest that the influence of 6-MU is mediated at least partly by a specfically anabolic effect.
