[Relaxing and constricting factors derived from vascular endothelium].
The Author summarizes the factors produced in vascular endothelium in response to different stimuli. The relaxing factor is identified as nitric oxide, a radical, whereas the constricting factor, endothelin, is a peptide. Their actions are related to several situations, both normal and pathologic, still poorly understood.
