Figure 8-13 Livers from rats exposed to halothane (A), enflurane (B), isoflurane (C), desflurane (D), or oxygen (E), were incubated with anti-trifluoroacetyl rabbit serum to detect the presence of trifluoroacetylated liver proteins, after anesthetic exposure. Evidence of an immune response to trifluoroacetylated liver proteins can be seen in A, B, and C. No immunoreactivity is evident in D or E.
