22 A. D. Hughes Biochemical mechanisms of sensitization and desensitization Recently, our understanding of the biochemistry of Ca2+-sensitization has improved considerably. Work in skinned smooth muscle using techniques which irreversibly permeabilize the smooth muscle cell but preserve receptor coupling has been able to replicate the increases in Ca2+-sensitivity seen with contractile agonists (PWtzer and Arner, 1998). Studies have shown that this eVect can be mimicked by application of GTP- -S or AlF4−, and blocked by GDP- -S – non-hydrolysable analogues of GTP and GDP respectively.

A poorly compliant or stiV aorta will result in an excessive rise in systolic blood pressure and precipitous fall in blood pressure during early diastole. Conversely, a compliant aorta acts as a cushion or windkessel, reducing the rise in systolic blood pressure. , 1999). The windkessel eVect has importance not only in reducing systolic blood pressure but also in increasing diastolic blood pressure. This, in turn, may have important implications for coronary artery blood Xow which occurs mainly during diastole.
