实验性的:Cutaneous Vascular Response to Local Heat
All women will complete the same protocol, regardless of pregnancy history and depression status. Four intradermal microdialysis fibers will be placed in the ventral forearm for the local delivery of: (1) lactated Ringer's (control), (2) paroxetine HCl, (3) ascorbic acid, or (4) paroxetine HCl + ascorbic acid. Skin blood flow will be measured with laser-Doppler flowmetry directly over each microdialysis fiber during a standard local heating protocol to 42 degrees Celsius. Once a stable plateau in blood flow has been reached, each site is perfused with L-NAME to inhibit nitric oxide synthase. Following a post-L-NAME plateau, maximal dilation is induced by perfusing sodium nitroprusside and increasing local temperature to 43 degrees Celsius. |
