Effects of diprophylline on jejunal contractility pretreated with tetrodotoxin (TTX) and imatinib respectively. (A1) Representative traces and (A2) statistical analysis of diprophylline (20 µM)-induced effects on jejunal segment pretreated with tetrodotoxin (0.1µM). (B1) Representative traces and (B2) statistical analysis of diprophylline on the contractility of jejunal segment pretreated with c-Kit tyrosine kinase blocker imatinib. Contractile amplitude of jejunal segment in normal contractile state is set to100% (normal control, NC). Data are expressed as the mean±SEM (% NC, n=6). ^**p<0.01 compared with contractile amplitude of jejunal segment after treatment with TTX or imatinib. RLCS, representative low contractile state; RHCS, representative high contractile state.
