Figure 2. The effect of QCT on IC/BPS rats. ELISA kit detected the concentration of IL-1β (A), IL-6 (B), MPO (C), TNF-α (D). (E) HE staining was used to deserve the inflammatory of bladder tissue in rat. (F, G) Changes of collagen fibers in rat bladder tissue was performed by Masson staining. (H, I) TB staining observed the mast cells in bladder tissue of rat. (J) The degranulation of mast cells in rat bladder tissue was observed by transmission electron microscope. One-way ANOVA was used. Compared with Ctrl group, **P < 0.01, ***P < 0.001. Compared with IC/BPS group, ΔP < 0.05, ΔΔP < 0.01, ΔΔΔP < 0.001. n = 3.
