  • Title: Postmortem biochemical changes in canine cerebrospinal fluid.
    Author: Schoning P, Strafuss AC.
    Journal: J Forensic Sci; 1980 Jan; 25(1):60-6. PubMed ID: 6771360.
    Abstract:
    Time and temperature effects on postmortem cerebrospinal fluid samples from 60 adult mongrel dogs were studied. After death the dogs were held at 4, 20, or 37 degrees C for intervals of 3, 6, 12, 24, or 48 h. Antemortem and postmortem cerebrospinal fluid was evaluated for sodium, chloride, potassium, urea nitrogen, glucose, creatinine, calcium, phosphorus, and carbon dioxide. Sodium and urea nitrogen values remained stable. Chloride may be of forensic science value. Low levels of postmortem calcium might indicate antemortem hypocalcemia; high levels of postmortem glucose may indicate antemortem hyperglycemia. Calcium and creatinine levels increased slightly but continually after death; carbon dioxide values dropped.
