A preliminary pathological study on human allotransplantation
摘要
Objective: To observe the survival of hand allograft under the state of immunosuppression and the pathological changes of rejection in the recovery process.Methods: The biopsies of the skin, nerve, muscle, tendon and bone tissue of hand allografts during different stages from 1 day to 7 months after operation were observed using routine histological technique.Results: No significant changes due to rejection in skin, nerve, muscle and bone tissue were observed.But different degrees of weak rejective changes were found on the wall of blood vessels; in the muscle and nerve the reactions were markedly stronger than those found in skin tissues.Conclusions: The rejection in deep tissues should be monitored in controlling the rejection of hand allograft.
