  • Title: Postmortem magnesium concentration in bovine vitreous humor: comparison with antemortem serum magnesium concentration.
    Author: Lincoln SD, Lane VM.
    Journal: Am J Vet Res; 1985 Jan; 46(1):160-2. PubMed ID: 3970421.
    Abstract:
    The range for postmortem vitreous humor Mg2+ concentration in 97 healthy cattle was 1.8 mg/dl to 2.72 mg/dl at 23 C for a 48-hour postmortem interval. The postmortem vitreous Mg2+ concentration closely paralleled the antemortem serum Mg2+ concentration at 23 C. Low environmental temperature (4 C) had no effect on postmortem vitreous concentration. However, high environmental temperatures (30 C) significantly (P less than 0.05) reduced postmortem vitreous Mg2+ concentration at the 36-hour postmortem interval. It was concluded that postmortem vitreous humor Mg2+ determination could be a useful diagnostic aid in cattle for detecting Mg2+ imbalances for at least 48 hours after death, provided the postmortem environmental temperature did not exceed 23 C after 24 hours.
