Studies were conducted with rats to investigate whether platelet activating factor (PAF) and nitric oxide (*NO)-derived oxidants played roles in the initial adherence of neutrophils to vasculature in the brain after carbon monoxide (CO) poisoning. Before CO poisoning, rats were treated with the competitive PAF receptor antagonist WEB-2170 or with the peroxynitrite scavenger selenomethionine. Both agents caused significantly lower concentrations of myeloperoxidase in the brain after poisoning, indicating fewer sequestered neutrophils.

OBJECTIVE: To observe the levels of platelet-activating factor (PAF), interleukin-6 (IL-6) and IL-17 in peripheral blood of rats with adjuvant arthritis (AA), and the effects of Xinfeng Capsule (XFC), a compound traditional Chinese herbal medicine. METHODS: A total of 40 male Sprague-Dawley rats were randomized into normal control group, model group, methotrexate (MTX) group, Tripterygium Wilfordii polycoride Tablet (TPT) group, and XFC group, respectively. AA was induced in rats by intracutaneous injection of 0.1 mL Freund's complete adjuvant in the right hindlimb.
