Research Abstract

In the present project we performed the two main studies to clarify the pathophysiology of endotoxin-induced lung injury using awake sheep with chronic lung lymph fistula. First study is to see the pathophysiology of TNF (tumor necrosis factor)-induced lung injury. After infusion of recombinant human TNF (r-hTNF) produced the almost same lung injuries as endotoxin-induced lung injury which we have reported^<1)>, such as the early pulmonary hypertension, transient leukopenia, decreased PaO_2 and the increased permeability pulmonary edema during the late phase. Pretreatment of selective thromboxane synthetase inhibitor, OKY-046, inhibited the early pulmonary hypertension induced by TNF, though other lung injuries did not change. Furthermore, the appearance of lung injuries induced by TNF occurred earlier 0.5-1hr than that induced by endotoxin. Secondly we examined the effects of recombinant human superoxide dismutase (r-hSOD) on endotoxin-induced lung injury to see the role of superoxide anion (O_2^-). Treatment of r-h SOD suppressed lung injuries as mentioned above, but the degree of inhibition was approximately half.
These results suggest that the mechanism of endotoxin-induced lung injury in awake sheep is complicated. O_2^- has an important role in this injury. However, we need to study the role of other oxygan radicals than O_2^- and some chemical mediators such as proteases. TNF infusion resulted in the same lung injury as that caused by endotoxin. Recently, intravascular macrophages (M*) are thought to have a central role in the development of endotoxin-induced lung injury. M* releases several mediators when stimulated by endotoxemia, and these mediators lead to lung injury. We need further studies to see whether TNF is crucial among these mediators.
