Proinflammatory and prothrombotic status in emphysematous rats exposed to intermittent hypoxia.

ABSTRACT:

Objectives

To develop an "overlap syndrome (OS)" rat model by intermittent hypoxia (IH) exposure on the base of pre-existing emphysema, and to explore whether "OS" exposure results in more severe systemic inflammation, and whether the inflammation changes levels of coagulant/anticoagulant factors and oxidative stress status.

Methods

Sixty Wistar rats were put into 4 groups: Control group; IH group, IH exposure; Emphysema group, smoke exposure; Overlap group, smoke exposure and IH exposure. We obtained peripheral blood for apoptosis of CD3(+)CD4(+), CD3(+)CD8(+) T lymphocytes and neutrophils, and for endothelial progenitor cell (EPC) counts. Tumor necrosis factor (TNF)-α, interleukin (IL)-6 and coagulant/anticoagulant factors [antithrombin (AT), fibrinogen (FIB), Factor VIII
