Abstract:
Objective To study the characteristics of organ function and structural injuries in the elderly with multiple organ dysfunction syndrome. Method 50 Wistar rats (25 three-month-old rats and 25 twenty-month-old rats) were anaesthetized and experienced cecal ligation puncture (CLP) operation, which were defined as MODSE group and MODS group respectively. 40 Wistar rats (20 three-month-old rats and 20 twenty-month-old rats) were anaesthetized and not experienced cecal ligation puncture operation, which were used as SOGE (sham operation group in the elderly) and SOG (sham operation group). At 6 h, 12h, 24h, 48h or 72h after operation, serum levels of alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, creatinine and total bilirubin were measured by automatic biochemistry analyzer. Organs (hearts, brains, lungs, livers, kidneys) were harvested. Paraffin sections were made and stained by conventional H.E procedure for histological examination. Results Based on histological investigations, physiological and biochemical measurements, organ dysfunction in MODSE group occurred at 6h after operation and peaked at 24 h after operations. Otherwise, organ injuries with MODS occurred at 24 h and peaked at 48 h after operation. Conclusion According to histological investigations, physiological and biochemical measurements, damages of organ dysfunction and structural damages in MODSE group occurred much earlier and more seriously. which may provide an experimental evidence for medico-legal certification of the death caused by MODS.
