Plasma levels of hemopexin after treatment with silica particles. BALB/c mice were treated intravenously with 0.8 mg/mouse nSP70, nSP300, or mSP1000. (A) After 6, 24, and 72 h, the plasma levels of hemopexin in the mice were determined by ELISA. (B) BALB/c mice were treated intravenously with 0.05, 0.2, or 0.8 mg/mouse nSP70. After 24 h, blood samples were collected. The plasma levels of hemopexin in treated mice were determined by ELISA. Data are presented as mean ± SEM (n = 5; Double asterisks denote P < 0.01 versus the value for saline-treated group by ANOVA).
