ABSTRACT: Not only is the renin angiotensin system or its components found morphologically in many organs, it also exerts many different regulatory functions such as contributing to systemic homeostasis as well as to organ-specific regulation. The presence of the components of the renin angiotensin system in the pancreas was discovered only a few years ago. Physiological and pathophysiological stimuli were able to modify, in part, the gene expression and the occurrence of some of these components. Because of the important clinical significance of pancreatic diseases such as pancreatitis, research should follow every traces of the renin angiotensin system in the pancreas: impairment of microcirculation via hypoxia mediated up-regulation with the subsequent further deterioration of the oxygen supply seems to be the most obvious mechanism. There are many possible approaches to a better understanding of problems that are associated with diseases such as different kinds of pancreatitis; basic studies in animal models are oriented toward microcirculation, cellular function and the time course of modified gene expression after stimuli such as hypoxia; a clinical approach must reevaluate different correlations between clinical parameters of hypertension and those of pancreatic diseases.
