Postmortem Sera and Cerebrospinal Fluid Enzymes
Antemortem and postmortem sera from 60 dogs were evaluated for lipase, amylase, alkaline phosphatase, γ-glutamyltransferase, and alanine aminotransferase (AAT); cerebrospinal fluid was examined for AAT and alkaline phosphatase. The postmortem intervals were 3, 6, 12, 24, and 48 h at temperatures of 4, 20, and 37°C Amylase levels remained stable at 4 and 20°C and may be beneficial for diagnosing pancreatitis. Lipase levels may be useful as an adjunct to amylase values. Serum alkaline phosphatase values increased with postmortem interval; values were higher at 37°C than at 4°C Other enzymes were of little value for diagnosis.
