Plasma and lung CARs levels in air breathing mice fed BC (0.5 g/kg diet) or LY (0.5 g/kg diet) supplemented diet after 1, 2 and 4 weeks. a Plasma levels of BC and LY increased after 1 week. BC levels decreased after 2 and 4 weeks but LY levels were maintained for 4 weeks (n = 4 mice per group). b Lung BC levels (nmol/kg lung tissue) increased after 1 week and decreased after 2 and 4 weeks and appear to track the plasma BC levels. Lung LY levels increased after 1 week, and its levels slightly increased after 4 weeks (n = 4 mice per group) (N.D not detected)
