Prenatal Aspirin and Postpartum Vascular Function

acetylcholine, and acetylcholine + L-NAME (Nitric oxide synthase inhibitor) are locally and acutely delivered to the cutaneous microvasculature to assess endothelium- and nitric oxide-dependent dilation

endothelin-1, endothelin-1 + BQ-788 (endothelin receptor type B-inhibitor), and endothelin-1 + BQ-123 (endothelin receptor type A-inhibitor) are locally and acutely delivered to the cutaneous microvasculature to assess endothelin-mediated constriction and the role of the receptor subtypes in this response.
