Postmortem Analyses Unveil the Poor Efficacy of Decontamination, Anti-Inflammatory and Immunosuppressive Therapies in Paraquat Human Intoxications
Figure 5
Light micrographs of gastric (A and B) and duodenal (C and D) wall from paraquat human fatal poisonings stained with hematoxylin-eosin.
In A and B, it is observed necrosis of epithelial cells with desquamation and mucosal infiltration of mononuclear cells (#). There are also sings of submucosal edema (*). In C and D, epithelial necrosis affecting the villi and crypts with loss of mucosal villi structure, infiltration of mononuclear cells (green arrow), vascular congestion (red arrow), mucosal and submucosal edema, was particularly notorious.
