Ischemia followed by reperfusion leads to severe organ injury and dysfunction. Inflammation is considered to be the most important cause of tissue injury in organs subjected to ischemia. The mechanism that triggers inflammation and organ injury after ischemia remains to be elucidated, although different causes have been postulated. We investigated the role of apoptosis in the induction of infla...

INTRODUCTION Thyroid storm is an endocrinological emergency caused by an exacerbation of the hyperthyroid state and is characterized by multi organ dysfunction. Liver dysfunction or injury predominantly of a cholestatic type is one of the atypical manifestations of thyroid storm and has been previously described in literature. However, there have been few published case reports among African pa...

INTRODUCTION Ventilator-induced lung injury (VILI) contributes to morbidity and mortality in acute respiratory distress syndrome (ARDS). Particularly pre-injured lungs are susceptible to VILI despite protective ventilation. In a previous study, the endogenous peptide adrenomedullin (AM) protected murine lungs from VILI. We hypothesized that mechanical ventilation (MV) contributes to lung injury...

Ischemia/reperfusion injury is a reaction occurring after successful treatment of an acute myocardial infarction or in the setting of solid organ transplantation. After successful reperfusion of a previously occluded vessel or a transplanted organ, an additional loss of otherwise vital cells may occur, the so-called lethal ischemia-reperfusion injury. This lethal reperfusion injury is based on ...

ISCHEMIA contributes to the pathophysiology of many conditions faced by anesthesiologists, including myocardial infarction, peripheral vascular insufficiency, stroke, and hypovolemic shock. Although restoration of blood flow to an ischemic organ is essential to prevent irreversible cellular injury, reperfusion per se may augment tissue injury in excess of that produced by ischemia alone. For ex...

Organ cross talk exists in many diseases of the human and animal models of human diseases. A recent study demonstrated that inflammatory mediators can cause acute kidney injury and neutrophil infiltration in a mouse model of dextran sodium sulfate (DSS)-colitis. However, the chemokines and their receptors that may mediate distant organ effects in colitis are unknown. We hypothesized that kerati...

Endotoxemia is a life-threatening, inflammatory condition that involves multiple organ injury and dysfunction. Preprotachykinin-A (PPT-A) gene products, substance P (SP), and neurokinin-A have been shown to play an important role in neurogenic inflammation. To investigate the role of PPT-A gene products on multiple organ injury in LPS-induced endotoxemia, endotoxemia was induced by LPS administ...
