Figure 7: Effects of DCHJ on a mouse model of skin transplantation. BALB/c mice were given a gavage of DCHJ 3 days prior to skin transplantation. At day 0, full-thickness skin allograft transplantation was performed as described in Section 2. (a) The MST of skin grafts was recorded using Kaplan-Meier tests ( mice per group). ; . (b) Histological analysis of skin grafts revealed normal tissue structures with less lymphocyte infiltration and no necrosis in the heterogenic experimental group compared to that in the heterogenic control group (×100, ×400).
