Abstract
- We demonstrated the dynamic aspects of granulocyte activation in rat severe acute pancreatitis which was induced by cerulein and aggravated following lipopolysaccharide (LPS) injection. Pancreatitis induced by cerulein increased intracellular elastase activity of granulocytes in the blood. However, significant systemic cytokinemia was not provoked under such conditions. After induction of severe pancreatitis by LPS, intracellular elastase activity of circulating granulocytes decreased markedly and immediately. The timing of this decrease was concomitant with induction of systemic hypercytokinemia and granulocytes migration into the lung. Overall results provide the following implications: (1) circulating granulocytes are activated by the induction of mild pancreatitis; (2) the activation of granulocytes is mediated by other factors than systemic cytokinemia, such as locally produced cytokine; (3) those priming granulocytes immediately and significantly migrate from the circulation into extravascular space by the induction of endotoxemia; (4) the migration of granulocytes, in turn, may be mediated by systemic cytokinemia.
