Effects of PDTC on NF-κB expression and apoptosis in rats with severe acute pancreatitis-associated lung injury.

We investigated the effects of pyrrolidine dithiocarbamate (PDTC) on intrapulmonary expression of nuclear factor-κB (NF-κB), and apoptosis in rats with severe acute pancreatitis (SAP). We induced SAP, then used immunohistochemistry, TUNEL staining, quantitative PCR assays and western blotting to examine PDTC effects. Treatment with PDTC resulted in interstitial edema and widening of the basement membrane, with swollen mitochondria and aggregation of nuclear chromatin.
