Inhibition by sodium nitroprusside of the expression of inducible nitric oxide synthase in rat neutrophils.

abstract：BACKGROUND AND PURPOSE:Kinins are pro-inflammatory peptides that are released during tissue injury, including that caused by inflammatory bowel disease. Herein, we assessed the role and underlying mechanisms through which the absence of kinin B(1) receptors exacerbates the development of dextran sulfate sodium (DSS)-i...
