Table 2 Effects of sulforaphane (SF) administration and deep inspiration on A. Changes in forced expiratory volume in 1-second (FEV1) produced by the bronchoconstrictor MCh, and B. Magnitudes of bronchoprotection (BP) and bronchodilation (BD) effects

From: Sulforaphane improves the bronchoprotective response in asthmatics through Nrf2-mediated gene pathways
