Dose-response predictability of urinary bladder hyperplasia by N-2-fluorenylacetamide feeding in mice: its modification by sex.

Haley TJ, Schieferstein G, Jaques WE, Farmer J, Frith C, Sprawls RW


A serial sacrifice experiment involving urinary bladder hyperplasia, produced by feeding 8¿86 ppm of N-2-fluorenylace-tamide for 90 days to BALB/c mice, showed a dose¿response relationship for males but not females. The information from this study was used in a statistical design to predict the percent of hyperplasia in relation to time and dose. A formula for establishing the confidence limits of the curve was derived. Sex-dependent spontaneous pericardial fibrosis and mineralization were also observed, with the male response being twice that of the female.
