Antiulcerogenic Activity of Li-Zhong Decoction on Duodenal Ulcers Induced by Indomethacin in Rats: Involvement of TLR-2/MyD88 Signaling Pathway

Figure 3

(a) Duodenal histopathology showing the protective effects of LZD on IND-induced histological alteration in rat duodenum. The circles indicate intestinal villi. The dashed circles indicate intestinal crypts. The star indicates infiltration of inflammatory cells. The arrows indicate destruction and desquamation of intestinal villi. (b). Microscopic scores in duodenal tissues of rats of different experimental groups. (c). Histographic representation of villus height change during ulceration and protection. (d). Histographic representation of crypt depth change during ulceration and protection. Vertical bars represent standard errors of the means, n = 6. Asterisks and pound signs indicate significant differences: versus normal control (NC); ^## versus negative control (IND).
