Effects of initiating time and dosage of Panax notoginseng on mucosal microvascular injury in experimental colitis

Figure 2 Panax notoginseng improved hypoxia in colonic mucosa. A-F: Increased expression of hypoxia-inducible factor-1α in colonic mucosa of the experimental colitis group was down-regulated by PN in a time- and dose-dependent manner. Results are expressed as mean ± SD of three independent experiments performed in triplicate. ^aP < 0.05, ^bP < 0.01 vs normal control. PN: Panax notoginseng.
