The ability of nonsteroidal anti-inflammatory drugs and cyclooxygenase-2 inhibitors to exacerbate inflammatory bowel disease suggests that prostaglandins are important anti-inflammatory mediators in this context. Prostaglandin D(2) has been suggested to exert anti-inflammatory effects. We investigated the possibility that prostaglandin D(2) derived from(More)
The inducible nitric oxide synthase (iNOS) present in vascular smooth muscle cells (VSMC) may play a role in the generation of nitric oxide (NO) in the vascular wall, regulating blood vessel tone in normotension and hypertension. In this study the effect of interleukin (IL)-1 beta, a cytokine that induces iNOS, on NO generation (measured as nitrite), cyclic(More)
This study was done to determine if a decrease in the aldosterone-suppressant effect of atrial natriuretic factor (ANF) by progesterone and an increase by estrogen was caused by modulation of adrenal zona glomerulosa ANF receptors. Freshly dispersed glomerulosa cells from virgin, 13-15 day pregnant, ovariectomized (OVX) estradiol-17 beta-treated and OVX(More)
The nitric oxide synthase (NOS) inhibitor L-NAME may have growth inhibitory effects in vivo. We investigated in vitro the potential growth inhibitory effects of three different NOS inhibitors: L-NAME (1 mM), LNMMA (1 mM) and aminoguanidine (0.5 mM), on fetal bovine serum (FBS) and platelet derived growth factor (PDGF-BB)-stimulated growth in cultured(More)
