Figure 2. Differential expression of SCF, NSE in colonic samples. (A) HE staining performed on colonic tissues [original magnification ×40]. saline group (A), morphine group (B), rhubarb group (C), morphine+rhubarb group (D). (B) IHC staining (anti-SCF) performed on colonic tissues [original magnification ×40]. I morphine group, II: morphine+rhubarb group (STC). (C) the mRNA expression of SCF, NSE expression in cathartic colon mice models. (D) the protein expression of SCF, NSE in cathartic colon mice models. *P<0.05 versus saline group, #P<0.05 versus morphine group.
