We performed this study to develop a reliable method for inducing colitis in rats using 2,4,6-trinitrobenzene read more sulfonic acid (TNBS) to reduce the variation in ulcer size.A pair of ring forceps was used to clamp the colon and 0.1 M TNBS in ethanol was injected into the luminal side of the clamped portion.

This method resulted in a small coefficient of variation of the ulcer index.A significant linearity was observed Latest Product Releases & Innovations – Stay Updated! by plotting ulcer size against days after ulcer induction in both logarithm scales.These findings show that this technique is simple and reliable and that ulcers heal linearly.
