Box 50, Newark, Delaware 19711 HASRELL LABORATORY REPORT NO. 323-82 Material Tested Octanoic acid, pentadecafluoro-, ammonium sale* Haskell No. 12,037 Other Codes Study Initiated/Completed 2/11/82 - 3/4/82 .Material Submitted by CR&D Department Haskell Laboratory MOUSE FEEDING STUDY - 21 DAYS ft Summary: was fed to male and female Crl:CD-l mice at 8' lose levels (from 0.01 ppm o 30 ppm) for 21 consecutive** days. Livers were signtticantly heavier at 30 ppm, slightly heavier at 3 Ppm and appeared nonnal at 10 ppm in male and female mice. No changes in liver weight were seen at feeding levels ot 1 ppm or lower and the significance of the change observed at 3 ppm, in light of no differences at 10 ppm, is questionable. The only clinical sign observed was sporadic weight loss. Procedure: Forty-five male and 45 female albino Crl:CD-l mice (ages 41 and 42 days, weighing 21-33 g) were grouped by body weight, 5 animals per group, fJe&df l by computerized randomizjcion. The mice were housed individually and for" (suspended in IZ corn oil before being mixed in ground Purina Lab Chowft*) for 21 consecutive days at dose levels of either 30, 10, 3, 1, 0.3, 0.1, 0.03 or 0.01 ppm. An additional group of male and female mice served as controls and received ground Purina Lab Chow only. Individual body weights were recorded weekly, clinical signs daily and liver weights at the 21-day sacrifice. 1 - contain TSC^CBI Sanrtteed.Doesn, o Cow?301/ Results: Male Mice Dose Level pun 0 30 10 3 1 0.3 0.1 0.03 0.01 Body Wt(g) 1 Week 30 32 30 31 31 32 32 '0 33 Body Wt(g) 2 Weeks 32 34 32 34 32 34 34 33 35 Body Mt(g) 3 Weeks 33 33 33 34 33 34 35 33 36 Average liver Weights (g) 1.82 4.61*** 1.87 2.45 1.89 1.83 1.82 1.91 2.07 Average Liver wt./ Body Wt.
