Morphological effects of mitomycin c administered intravesically to normal mice and mice with af-[4-(5-nitro-2-furyl)-2-thiazolyl]- formamide-induced bladder neoplasms

The intravesical administration of mitomycin C to normal and N-[4-(5-nitro-2-furyl)-2-thiozolyl]formamide-induced bladder tumor-carrying mice at initial concentrations of 2 and 5 mg/ml for 2 hr resulted in marked morphological effects including cytoplasmic and nuclear abnormalities and disruption of surface architecture. Tumor cells and normal urothelial cells were sensitive to the effects of mitomycin C. These effects were limited to epithelial cells.
