Research Abstract

Abundant inflammatory cells such as leukocytes and macrophages accumulated and adhered to the endothelial surface of the vascular vessels after administration of bacterial lipopolysaccharide(LPS). There is also marked endothelial cell damage including intracytoplasmic edema, increased numbers of autophagic vacuoles and dilatation of the intercellular junction in LPS-treated samples. The degeneration of parenchymal cells such as hepatic necrosis, renal proximal tubular cell necrosis and edematous muscle cells of the myocardium also observed in LPS-treated sample. The presence of immunocytochemical products of leukotriene(LT) and tumor necrosis factor(TNF) was examined using in LPS-treated samples. Immunoreactions of LT seen in the lysosomes of inflammatory cells attached to the endothelial cell surface may indicate the onset of endothelial cell damage. Positive immunoreactions of TNF on the endothelial cell surface indicate that TNF may enhance the adhesion of leukocytes to endothelium. In addition to these reactios sites, lysosomes of the degeneration of parenchymal cells such as hepatic necrosis, renal proximal tubular cell necrosis and edematous muscle cells of the myocardium were immunoreactive for TNF or LT.These degeneration of parenchymal cells is primarily caused by endogenous TNF or LT rather than by ischemia.
