Q: Given a passage with a context and an answer, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.
Context: Intestinal ischemia/reperfusion (I/R) injury is believed to be the major initiator of the systemic inflammatory response syndrome. As a result of intestinal I/R, the gut becomes a major source of inflammatory cytokine production. We have previously shown that heparin-binding EGF-like growth factor (HB-EGF) is cytoprotective after intestinal I/R and down-regulates pro-inflammatory cytokine production in vitro. We now examine the effects of HB-EGF on pro-inflammatory cytokine expression in vivo.', 'Rats were randomized into three groups: sham-operated, superior mesenteric artery occlusion (SMAO) for 90 min followed by 8 h of reperfusion (I/R), and I/R with intraluminal administration of HB-EGF 25 min after the initiation of ischemia (I/R + HB-EGF). Serum was drawn at 2, 4, 6, and 8 h post reperfusion for determination of cytokine protein levels using a bioplex suspension array system. Additional animals underwent the same ischemic protocol followed by 30 and 60 min of reperfusion with harvesting of ileal mucosa. Ileal pro-inflammatory cytokine gene expression was determined using reverse transcriptase polymerase chain reaction (RT-PCR) with primers specific for TNF-alpha, IL-6, and IL-1beta.', 'HB-EGF decreased TNF-alpha, IL-6, and IL-1beta serum protein levels at 4, 6, and 8 h after intestinal I/R injury. In addition, HB-EGF decreased local intestinal mucosal mRNA expression of TNF-alpha, IL-6, and IL-1beta 30 and 60 min after intestinal injury.
Answer: We conclude that pro-inflammatory cytokine expression is increased both locally and in the systemic circulation after intestinal I/R and that the administration of HB-EGF significantly reduces intestinal I/R-induced pro-inflammatory cytokine expression in vivo.
A:
Does heparin-binding EGF-like growth factor decrease inflammatory cytokine expression after intestinal ischemia/reperfusion injury?
