چکیده

Reye's syndrome affects children with a history of viral infection treated with aspirin. Its pathogenesis is unclear. Tumour necrosis factor (TNF) is released by macrophages activated by viral infection, endotoxin, and phagocytosis, and it has been shown to be a mediator of the toxic and metabolic effects of endotoxaemia. The metabolic effects of endotoxin and TNF are similar to those found in Reye's syndrome. Raised levels of TNF are released from macrophages treated with non-steroidal anti-inflammatory drugs, and young animals are known to be more sensitive than mature animals to both TNF and endotoxin. These observations lead to the hypothesis that an increased release of TNF in selected young patients treated with aspirin contributes to the development of Reye's syndrome.

Recombinant tumor necrosis factor causes activation of human granulocytes.

We have tested the hypothesis that tumor necrosis factor (TNF), by binding to and activating granulocytes, may contribute to the pathogenesis of gram-negative sepsis and the adult respiratory distress syndrome (ARDS). Buffy coat granulocytes incubated with as little as 0.5 ng/mL of recombinant TNF (rTNF) showed a dose-related increase in nitroblue tetrazolium dye reduction, in granulocyte polar...

Assessment of myocardial injury by serum tumour necrosis factor alpha measurements in acute myocardial infarction.

Clinical and experimental data have shown that after acute myocardial infarction there is a significant release of tumour necrosis factor alpha. Therefore, an attempt was made to correlate changes in serum tumour necrosis factor alpha concentrations with indices of infarct extent in patients with acute myocardial infarction. In 50 patients with acute myocardial infarction, blood samples for eva...
