Effect of phenylbutazone on acute hemorrhagic pancreatitis in dogs.

Experiments were conducted on 24 mongrel dogs to study the effect of phenylbutazone on acute experimental pancreatitis. Necrotico-hemorrhagic pancreatitis was produced by local infiltration of autologous bile. The severity of pancreatitis was assessed by biochemical estimation and histopathological examination. Pretreatment with phenylbutazone reduced the severity of pancreatitis, both biochemically and histologically (total score 6.0 +/- 1.52 in the test group vs 8.33 +/- 1.80 in the control group; p less than 0.01).
