ABSTRACT
AIM:
To evaluate the effect and safety of Rhodamine 123 (Rh123)-mediated photodynamic treatment (PDT) on acute graft versus host disease.METHODS:
An acute graft versus host disease (aGVHD) mice model was established using C57B/6 mice as donors and BALB/c mice as recipients. Mixed lymphocytic cells were cultured with Rh123 (50 nmol/L) and irradiated by argon laser 30 mW/cm2 for 3 min, then transplanted to BALB/c recipient mice mixed with donor bone marrow. Hepatopoietic recovery, aGVHD occurrence, survival time after transplantation and pathological changes were observed. In addition, CD3+CD69+ positive rates of MLC were examined by flowcytometry.RESULTS:
Occurrence of aGVHD decreased, degree of pathological manifestation became milder, survival rates were higher than non PDT groups. CD3+CD69+ rates of MLC cells treated with photodynamic therapy (PDT) and cultured for 24 h significantly decreased.CONCLUSION:
Rh123-mediated PDT can effectively prevent aGVHD of allogeneic bone marrow transplantation in mice.
