Role of phospholamban in NO/EDRF-induced relaxation in rat aorta.

abstract：:We studied the effect of interleukin-1 alpha (IL-1) on corticotropin-releasing hormone (CRH) secretion by explanted rat hypothalami in vitro. We also assessed possible mediation of arachidonic acid metabolites on IL-1-stimulated CRH secretion, by preincubating hypothalami with the cyclooxygenase inhibitor indomethacin...
