ABSTRACT
The aim of this study was to explore the effect of hyperbaric oxygen (HBO) preconditioning on the rejection of skin allograft in mice and its molecular mechanism. BALB/c donor mice and C57BL/6 recipients received hyperbaric oxygen preconditioning once a day for 7 days. After skin transplantation, the recipients were treated with cyclosporine A (CsA) intraperitoneally. Immunofluorescent staining technique and flow cytometry were used to observe the influence HBO on percentage of spleen lymphocytes CD3+, CD4+, CD8+ and cell adhesion molecule LFA-1 (CD11a/CD18). The results showed that as compared with control, the numbers of CD3+, CD4+, CD8+, CD4+CD11a+, CD4+ CD18+, CD8+CD11a+, CD8+CD18+ lymphocytes of spleen decreased in HBO preconditioning groups and CsA group, and decreased markedly in HBO preconditioning combined with CsA group (p<0.05); the general state of recipient mice in HBO preconditioning combined with CsA group was better than that of recipient mice received HBO preconditioning or CsA only. It is concluded that the method of HBO preconditioning combined with traditional immunosuppressive agent CsA has remarkable advantage in inhibiting the rejection of skin graft. Its molecular protective mechanism is correlated with the expression of adhesive molecules on T cell subsets.
