ABSTRACT
The physiologic effects of misonidazole (Ro-07-0582) were studied in BALB/cKa mice injected i.p. at 0.5 to 1.5 mg/g b.wt. A 2--4 degree C reduction of body core temperature was observed in unanesthetized mice the duration and degree of effect were dependent on dose. Normal core temperatures were restored when the serum level of misonidazole had fallen to 0.5 microM (100 micrograms/ml). Misonidazole (1 mg/g) produced a rapid postinjectional drop of heart rate (40%), respiration (45%) and body core (4 degrees C) temperatures which gradually returned to preinjection values 6 to 8 hr later. In addition, misonidazole administration (1 mg/g) enhanced the overall effect on body temperature induced by hexobarbital anesthesia by a factor of approximately 3. These results are discussed in relation to the use of mouse model tumor systems to give an estimate of the magnitude of the cytotoxic effect of misonidazole expected in humans.
