In nine cases of Shy-Drager syndrome, the changes in blood pressure and cerebral blood flow on sitting up from a supine position were studied. The influence of fludrocortisone, a synthetic mineralocorticoid, and L-threo-3,4-dihydroxyphenylserine (DOPS), a precursor of norepinephrine, on these changes was examined. On sitting up, the regional cerebral blood flow (rCBF) measured by Xe133 inhalation showed a tendency to decrease. Fludrocortisone reduced the fall of the mean blood pressure significantly. DOPS reduced the fall of both the diastolic blood pressure and rCBF significantly.
对9例夏伊-德雷格综合征患者,研究了从仰卧位坐起时血压和脑血流量的变化。研究了合成盐皮质激素氟氢可的松和去甲肾上腺素前体L-苏式-3,4-二羟基苯丝氨酸(DOPS)对这些变化的影响。坐起时,通过吸入Xe133测量的局部脑血流量(rCBF)有下降趋势。氟氢可的松显著降低平均血压的下降幅度。DOPS显著降低舒张压和rCBF的下降幅度。
