Regulating effect of TongXie-YaoFang on colonic epithelial secretion via Cl- and HCO3- channel

Figure 3 Effects of BaCl₂, 4-acetamido-4’-isothio-cyanato-stilbene-2,2’-disulfonic and 4,4′-diisothiocyanato-stilbene-2,2′-disulfonic acid on 5-HT-induced the changes of short-circuit current in rats. 5-HT-induced ∆Isc were similar in three groups after the intervention with BaCl₂, SITS or DIDS, respectively (P > 0.05, respectively). ∆Isc: the changes short-circuit current; SITS: 4-acetamido-4′-isothio-cyanato-stilbene-2,2′-disulfonic; DIDS: 4,4′-diisothiocyanato-stilbene-2,2′-disulfonic acid; TXYF: TongXie-YaoFang; NMS: Neonatal maternal separation; RS: Restraint stress; NH: No handlings as control.
