Central regulation of arterial blood pressure.

Vascular mineralocorticoid receptor and blood pressure regulation.

The mineralocorticoid receptor (MR) is a major regulator of blood pressure by modulating sodium balance and blood volume in the distal nephron. The discovery of MR expression in both endothelial and vascular smooth muscle cells a decade ago raised questions about its role in the vascular wall and its involvement in blood pressure regulation. In vitro and in vivo pharmacological studies have sho...

Regulation of choroidal blood flow during combined changes in intraocular pressure and arterial blood pressure.

PURPOSE To test the hypothesis that human choroidal blood flow (ChBF) may depend, not only on ocular perfusion pressure (OPP), but also on absolute mean arterial pressure (MAP) and intraocular pressure (IOP). METHODS There were two study days in an open design. On the first day, OPP was varied by elevating IOP during a squatting-induced increase in MAP (28 subjects). On the second day, only t...
