It characterised by hypotension vascular collapse, with failure organs within body. The role excessive nitric oxide (NO) production, cytokine-dependent induction inducible synthase (iNOS), development septic discussed. Emphasis placed upon signal-transduction process which iNOS induced NO cellular energy dysfunction abnormal function cardiovascular system liver during shock.
