[The role of oxygen free radical and free radical scavenger in septic and hemorrhagic shock].
The roles of oxygen free radical (O2-), lipoperoxide (LPO) and free radical scavenger were clinically and experimentally studied in septic and hemorrhagic shock. The reduction of hepatic tissue blood flow (TBF) were equalized in two groups (40-55% of normal level) and rats were subdivided into 3 groups: untreated, normal saline (NS) continuous IV and superoxide dismutase: SOD + catalase (S/c) continuous IV as free radical scavenger. ⋯ The neutrophil derived O2- was markedly elevated in Et shock animals as well as septic shock patients but no significant change was noted in hemorrhagic shock animals or non septic shock patient. SOD and catalase were effective for neutrophil derived O2- in septic shock whereas little beneficial effect was noted in hemorrhagic or non septic shock.

[Cellular metabolic consideration in the pathophysiology and the treatment of shock].
Shock is defined as the summation of cellular dysfunction and resultant impairment of the function in various organs. The typical such condition can be observed in shock-induced multiple organ failure (MOF). Therefore, the most effective and fundamental management against shock should be the improvement of such cellular dysfunction. ⋯ Since tissue hypoxia and humoral mediator have been considered to play a key role in the development of such cellular dysfunction, protease inhibitor was administered to such patients and oxygen metabolism was improved with catecholamine. The CIS improved among survived MOF patients following those treatments. These results suggest that the shock-induced MOF is the summation of the cellular dysfunction which can be assessed with the CIS, and that such cellular dysfunction could be improved through the therapeutic approach to the humoral mediators and/or tissue oxygen metabolism.
