Efeito da hipertermia na pancreatite aguda grave experimental

OBJECTIVE: The aim of this study is to evaluate the effects of hyperthermia post-treatment on taurocholate-induced severe acute pancreatitis (AP) in rats. METHOD: Severe AP was induced by retrograde injection of 2,5% or 5% taurocholate solution into the main pancreatic duct. After the AP induction, animals were heated in a cage with two 100 W lamps. Body temperature was increased to 39oC and maintained at that level for 45 minutes. 72-hours mortality rate, amylase serum levels, histology (edema, acinar necrosis and inflammatory infiltrate), vascular permeability, pancreatic water content and serum levels of IL-6 and IL-1 were determinated. RESULTS: Hyperthermia post-treatment on severe AP showed no evidence of alteration in all evaluated parameters. CONCLUSION: The findings suggest no beneficial effect of the thermal stress on inflammatoy edema and mortality rate in taurocholate AP model.
