Abstract

To discuss the role of gadolinium chloride (GdCl(3)) in lung injury associated with acute necrotizing pancreatitis (ANP). Experimental animals were randomized into five groups (n = 18 for each group): normal control group, ANP group, GdCl(3) pretreatment group, ANP GdCl(3) pretreatment group, ANP GdCl(3) treatment group. Rat ANP model was induced by intraductal administration of 3% sodium taurocholate. Alveolar macrophages (AM) were obtained by bronchoalveolar lavage. The blood gas assay, the ratio of wet/dry tissue, protein content of bronchoalveolar lavage fluids (BALF), the myeloperoxidase (MPO) of lung tissue and generation of TNFalpha and NO by AM were evaluated. The apoptosis of AM was checked by agarose gel electrophoresis analysis, transmission electric microscopy observation and cytometry propidium iodide single stained method. The lung tissue was examined by histology. The parameter of GdCl(3) pretreatment group compared with normal control group had no statistical significance (P > 0.05). The indicators of ANP GdCl(3) pretreatment group and ANP GdCl(3) treatment group were elevated compared with the normal control group and had statistical significance (P < 0.05). But compared to the ANP group, they were all decrease...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
