Higher resistance of germfree mice to dianhydrodulcitol, a lymphotropic cytostatic agent.
The same dose of dianhydrodulcitol (DAD) produced a lower mortality rate among germfree mice than among SPF or conventional C3H mice. On the other hand, it caused graver lymphoid atrophy in germfree mice. Their higher resistance, as evidenced by the mortality rate, can be explained on the basis of a histological study of the ileum. It showed milder alterations of the intestinal wall in germfree than in SPF mice. The lymphotropic cytostatic agent had a less direct toxic effect in germfree mice, due to the lacking damaging effect of endotoxin from the normal intestinal flora.
