Figure 9From: Inhalation exposure to nanosized and fine TiO2 particles inhibits features of allergic asthma in a murine modelExpression of antibodies. Levels of ovalbumin (OVA) specific antibodies IgE (A) and IgG2a (B). Results are shown in relative units (RU) for healthy (PBS) and allergic (OVA) mice exposed for 2 hours a day, three days a week, for four weeks at a concentration of 10 mg/m3 to nanosized (nTiO2) or fine (fTiO2) TiO2 or left unexposed (-). N = 8 mice per group. The bars represent mean ± SEM; ** P < 0.01 significantly different from unexposed control; Mann-Whitney U test.Back to article page
