Abstract:
Objective To study the effect of pentoxifylline (PTX) on acute lung injury (ALI) in murine sepsis induced by intra abdominal infection. Methods Wistar rats were subjected to sepsis caused by cecal ligation and puncture (CLP), and animals were randomly divided into normal controls ( n =6), sepsis group ( n =18), and PTX treated group ( n =18). Pulmonary biopterin, nitric oxide (NO) levels, and pulmonary myeloperoxidase (MPO) activities were measured, guanosine triphosphate cyclohydrolase Ⅰ (GTP CHI), inducible nitric oxide synthase (iNOS), and tumor necrosis factor ? (TNF ?) mRNA expression were determined.Results Early treatment with PTX significantly decreased pulmonary MPO activities and TNF ?mRNA expression at 2 hours after CLP. Meanwhile, pulmonary biopterin, NO, GTP CHI, and iNOS mRNA expression levels were much lower in the treatment group than those in the non treatment group ( P
