Membrane Potential and Calcium Influx in Vascular Muscle from Spontaneously Hypertensive Ratscle cells. Even in veins of new-born SHR, where blood pressure is normotensive, there is a significant shift towards a preponderance of the L-type, rather than the T-type, calcium channel. Changes in calcium influx in SHR would be expected to result in important changes in vascular muscle cell functions.作者: 斜坡 時間: 2025-3-22 03:07

Discovery and Development of the Spontaneously Hypertensive Rathe selective inbreeding method developed hypertension without any special manipulation or experimental maneuvers. The fact that the SHR strain was obtained by only three repetitive selective inbreeding suggests that there are a few major hypertension genes and the genes are the primary cause of the blood pressure elevation in SHR.作者: 清澈 時間: 2025-3-25 18:36
Role of Second Messengers on Mobilization of Calcium and Related Events in Vascular Smooth MusclesFurthermore, the Na-Ca exchange diffusion mechanism is thought to contribute partly to the reduction in the free Ca.
