Expression of collagens I and III in each group (SABC×100). A and B: In hepatic fibrosis group, a large amount of collagen fibers distributed extensively in portals, hepatic sinusoids and hepatic parenchyma, along with the formation of fibrous septa and pseudo lobules; C and D: In non-DSHX-treated group, hepatic fibrosis was lightly alleviated compared with Figures A and B, while the collagen fibers were still expanded extensively and the fibrous septa could be seen apparently; E and F: In DSHX-treated group, fewer collagen fibers were distributed in portals and expanded lightly compared with Figures C and D. No pseudo lobules formed.
