Abstract | BACKGROUND: METHODS: Eighteen male rats were randomized into two groups: BB-94 (AP + 40 mg/kg/24 h BB-94 ip x three doses) or control (AP + 20 ml/kg/24 h normal saline ip x three doses). Necrotizing AP was induced by retrograde infusion of 5% sodium taurocholate (1.5 ml/kg) into the pancreatic duct. Twenty additional animals were randomized into BB-94 and control groups for the survival study. Serum was evaluated for amylase and MMP activity. Pancreatic sections were graded for edema, necrosis, neutrophil infiltrate, and hemorrhage. Myloperoxidase (MPO) activity was used to determine PMN infiltration in the lung. Evan's Blue dye extravasation was used to quantify vascular permeability. RESULTS: Animals in the BB-94 group had decreased amylase levels (1086.0 +/- 61.7 U/L vs 2232.7 +/- 309.9 U/L; P < 0.05), decreased cellular infiltrate (1.4 +/- 0.2 vs 2.3 +/- 0.2; P < 0.02), and decreased necrosis (4.1 +/- 0.3 vs 6.1 +/- 0.4; P < 0.005) compared to the control group. Lung tissue following pancreatitis in the BB-94 group demonstrated decreased MPO activity (41.5 +/- 2.4 units vs 57.3 +/- 2.9 units; P < 0.05) and decreased vascular permeability (18.3 +/- 2.8 mg/100 g vs 30.1 +/- 4.6 mg/100 g; P < 0.05). Animals treated with BB-94 had 100% survival compared to 50% survival in control at 72 h. CONCLUSIONS:
Pancreatitis results in increased local and distant MMP activity. Pulmonary and pancreatic injury following AP can be abrogated by treatment with an MMP inhibitor (Batimistat; BB-94) which may result in decreased morbidity and mortality.
