Experimental transmission of Powassan virus (Flaviviridae) by Ixodes scapularis ticks (Acari:Ixodidae)

Systematic inflammatory response syndrome, SIRS, is one of the biological responses to surgical and anesthetic invasions. SIRS itself is a defense response, but excessive SIRS may result in post-operative failure of major organs. There is evidence that inflammatory cytokines play an important role in SIRS. Therefore it may be treated by regulating these inflammatory cytokines. Changes in inflammatory cytokines during the perisurgical period were discussed in relation to post-operative organ injury in patients who had undergone highly invasive procedures such as open heart surgery or resection of esophageal cancer to explore the possibility of anticytokine therapy.
