Fig. 5From: Primary genotoxicity in the liver following pulmonary exposure to carbon black nanoparticles in miceHepatic Saa1 mRNA expression levels in mice following intratracheal instillation (I.T.), intravenous injection (I.V.) and oral gavage (P.O.) of 162 μg of TiO2, CeO2 or CB measured 1 day after exposure. Particle exposed groups n = 9, vehicle control n = 9. All values are presented as mean + SD. Asterisks (**) denote P ≤ 0.01 and (***) P ≤ 0.001 of Saa1 mRNA levels in exposed groups versus vehicle control. Hashtag (#) denotes P ≤ 0.05 of Saa1 mRNA level in TiO2 vs CB groups. Crosses (†††) denote P ≤ 0.001 of Saa1 mRNA level in CeO2 vs CB groups. Double cross (‡) denotes P ≤ 0.05 and (‡‡‡) denote P ≤ 0.001 of Saa1 mRNA level in TiO2 vs CeO2 groupsBack to article page
