It was shown that of four syngeneic, murine tumors investigated, only those that evoked the generation of a state of concomitant anti-tumor immunity were susceptible to endotoxin-induced regression. Moreover, the temporal relationship between the generation of concomitant immunity and the onset of susceptibility to endotoxin-induced regression points to the likely possibility that tumor regress...

of 92%o of control values. All dogs survived the experiment without evidence of renal failure.
