The Aschner and Czermak-Hering tests were carried out in 7 normal young males and 15 elderly patients with cerebral arteriosclerosis. Alterations in the heart rate, blood pressure and blood flow in the internal carotid artery and brachial artery were studied by means of the on-line Doppler ultrasonic apparatus before, during and after the maneuvers, simultaneously and continuously. Aschner Test. Bradycardia, biphasic alteration of blood pressure, increase of blood flow in the internal carotid artery and decrease of blood flow in the brachial artery were observed in the maneuver. The changing rate of the findings was diversified individually. However, no significant difference was observed between the normal young males and the elderly patients. Side effects consisted of slight and transient nausea and dizziness in 6 subjects. Czermak-Hering Test. Bradycardia, hypotension, and decrease of blood flow in the brachial artery were observed in the maneuver. The changing rate of the findings is more conspicuous in the elderly patients than in the normal young males. Alterations in the blood flow in the internal carotid artery were observed. There was a conspicuous increase of the blood flow in the internal carotid artery on the noncompressed side during the maneuver in all the normal young males and in half of the elderly patients. The remainder of the elderly patients showed either no alteration or decrease of the blood flow in the internal carotid artery on the noncompressed side. Slight nausea in 2 subjects, slight dizziness in 5 subjects, and moderate disturbance of consciousness in 1 subject were observed as side effects. The results indicate that the Czermak-Hering test will be more advantageous in investigating the autonomic nervous function (vasovagal reflex) and autoregulation of cerebral circulation in elderly subjects.
对7名正常年轻男性和15名患有脑动脉硬化的老年患者进行了阿施纳（Aschner）试验和策尔马克 - 黑林（Czermak-Hering）试验。在操作前、操作期间和操作后，使用在线多普勒超声仪同时连续研究心率、血压以及颈内动脉和肱动脉的血流变化。阿施纳试验。在操作过程中观察到心动过缓、血压双相改变、颈内动脉血流增加和肱动脉血流减少。这些结果的变化率个体差异较大。然而，正常年轻男性和老年患者之间未观察到显著差异。6名受试者出现轻微且短暂的恶心和头晕等副作用。策尔马克 - 黑林试验。在操作过程中观察到心动过缓、低血压和肱动脉血流减少。老年患者中这些结果的变化率比正常年轻男性更明显。观察到颈内动脉血流的改变。在所有正常年轻男性和一半老年患者的操作过程中，未受压侧颈内动脉血流显著增加。其余老年患者未受压侧颈内动脉血流要么没有改变，要么减少。观察到2名受试者出现轻微恶心，5名受试者出现轻微头晕，1名受试者出现中度意识障碍等副作用。结果表明，策尔马克 - 黑林试验在研究老年受试者的自主神经功能（血管迷走反射）和脑循环的自动调节方面将更具优势。
