In all patients, with the exception of 1, the serum cholinesterase concentration increased after transplantation to normal levels, indicating good graft function (normal range, 5.3-13 U/mL). Under normal circumstances, MBL does not react with the host's own tissues, 21 but changes in cell surface glycations, as those seen after cellular hypoxia, may lead to increased MBL deposition and complement activation.
