Effects of Rho-kinase inhibition on prostaglandin-induced contraction. PGE₂ (A)-and PGF_2α (B)-induced contraction in the absence and presence of Y-27632 (1 μM) of guinea pig open-ring tracheal smooth muscle preparations. Data represent means ± s.e.mean of four (PGE₂) and seven (PGF_2α) experiments, each performed in duplicate.
