(A) ALT, (B) GGT, (C) ALP, (D) total bilirubin, (E) albumin, (F) total complement activity (CH50). (In order to reduce complement activity, cobra venom factor was administered to one baboon [B18508] on days −1, 0, and 1. The CH50 remained between 11-13% for 4 days). Dashed lines indicate B3108, in which CH50 was measured only pre-Tx and 6 days post-Tx (as well as in the donor pig).
