We developed a rat model of pulmonary arteriovenous malformations after cavopulmonary anastomosis. We sought to determine whether this model reproduces the angiographic and histologic features seen in the human condition. Eight Sprague-Dawley rats underwent a right superior cavopulmonary anastomosis with the use of microsurgical techniques. Between 2 and 13 mo, pulmonary angiography was performed, the animals were euthanized, and the lungs were removed. Microscopic sections of the lung were stained with an endothelial-specific antibody (von Willebrand factor). Microvessel density was determined by counting vessels staining positively for von Willebrand factor, and the shunted and nonshunted (control) lungs were compared for each animal. Pulmonary angiography revealed time-dependent development of arteriovenous malformations. Microvessel density demonstrated a time-dependent increase in the shunted lung compared with the control lung (simple linear regression of the ratio of the microvessel density of the shunted lung divided by the microvessel density of the control lung on time; R 2 = 0.79, P = 0.003). This animal model reproduces the same angiographic and microscopic features of pulmonary arteriovenous malformations that develop in humans after cavopulmonary anastomosis. This appears to be a valid model that may be used to further study etiologic mechanisms for this phenomenon.

Abstract Sepsis is a serious clinical condition resulting from severe infection. High rates of mortality and tissue damage have been reported in intensive care unit (ICU) patients with sepsis. Bovine lactoferrin (BLF) is a well-known 80-kDa glycoprotein in the transferrin family that inhibits sepsis in low-birth-weight neonates. The present study investigated the protective effects of BLF in a rat model of sepsis-induced acute lung injury (ALI). The wet/dry ratio, lipid peroxidation, antioxidant markers, total protein, total cell count, inflammatory markers and myeloperoxidase (MPO) levels were assessed. Histopathological analysis was also carried out. BLF treatment reduced the wet/dry ratio of lung tissue by 30.7% and 61.3%, and lipid peroxidation by 22.3% and 67%, at concentrations of 100 and 200 mg/kg, respectively. Superoxide dismutase (SOD), reduced glutathione (GSH), glutathione peroxidase (Gpx) and catalase were increased by more than 50% under treatment with 200 mg/kg BLF. Inflammatory markers, neutrophils, lymphocytes and total cell count were reduced by more than 50% under treatment with 200 mg/kg BLF. BLF treatment significantly reduced MPO activity, by 28.2% and 74.3%, at concentrations of 100 and 200 mg/kg, respectively. Neutrophilic infiltration and edema were observed in control rats. However, BLF treatment restored intestinal microvilli to the normal range and reduced inflammatory cell invasion. Collectively, these results suggest that BLF is an effective therapeutic agent against sepsis-induced ALI.
