Young Seo, Byung Keun Yu, Yeon Joung Oh, Yoon Lee, Young Yoo, Ji Tae Choung, Young Yull Koh
Clin Exp Pediatr. 2008;51(5):487-491.   Published online May 15, 2008
Purpose : Although Mycoplasma pneumoniae (M. pneumoniae) infection can cause wheezing in non-asthmatic children, the mechanisms of this symptom remain unclear. Vascular endothelial growth factor (VEGF) is a major mediator of angiogenesis and vascular permeability, and is also known to be elevated in cases of chronic pulmonary disease such as asthma. We hypothesized that VEGF may increase in children with...
