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

Figure 7

Localization of TLR-2 and MyD88 in duodenal tissues after IND administration and effect of LZD thereon. (a) Representative pictures showing the immunohistochemical analysis of TLR-2 and MyD88 in sections of duodenal mucosa obtained from rats in normal control, negative control, ESO, and LZD groups. The black arrows denote the immunopositive expression parts of TLR-2 and MyD88. Magnification 200x. (b, c) Quantitative analysis of the immunohistochemical signals as measured by IOD values. Results are expressed as the mean ± SEM (n = 3). Asterisks and pound signs indicate significant differences: versus normal control (NC); ## versus negative control (IND).
