动脉搏动

Methods It was measured that the blood flow of them with Acuson 128 computer imaging. Spectrum in 209 old people with velocity of systole and diasole phase, resistance and pulsate index.

方法采用美国Acuson－128型电脑影像仪测量209例老年人眼动脉和视网膜中央动脉的收缩期、舒张末期血流速度、阻力指数和搏动指数。

Arteriopathy of the central nervous system compli- cated with ulcerative colitis is a rare condition, moreover the involvement of extracranial arteries has not been documented. An 18-year-old female complained of a severe pulsatile headache and nausea. She had been diagnosed and treated for ulcerative colitis for four years.

文章摘要：中枢神经系统动脉病并发溃疡性结肠炎是一种罕见疾病，而关于脑外动脉受累的病例尚未见报道。1例18岁的女性患者主诉剧烈搏动性头痛和恶心，该患者被诊断为溃疡性结肠炎并接受治疗4年。

Essential hypertension caused by neurovascular compression of the left ventrolateral medulla was associated with malbalance of vasomotor center in the dorsal medulla. The possible pathogenesis was the following:① An irritation of the left RVLM by pulsatile compression of an ectatic vessel would increase activity of central sympathetic neuron.② Neurovascular compression at the REZ of the cranial nerves Ⅸ and Ⅹ decreased excitation of parasympathetic nerve.③ Decreased sensitivity of afferent inputs to neuron of nucleus tractus solitarii in the sensory area lead to hyperactivity of central sympathetic nervous system due to pulsatile compression of the left RVLM.④ Neurocompression of the left RVLM and REZ in the left cranial nerves Ⅸ and Ⅹ lead to an overactivity of central renin angiotensin system.

3，结论：左侧延髓腹外侧Ⅸ、Ⅹ颅神经REZ动脉血管压迫所导致的高血压的发生与左侧延髓血管运动中枢对血压的调节失衡有关，其可能机制是：①左侧RVLM在搏动性血管压迫刺激下，中枢交感神经元活性增高；②左侧Ⅸ、Ⅹ颅神经REZ受压导致副交感神经兴奋性降低；③感受区孤束核神经元接受迷走神经传入冲动的敏感性减低，导致中枢交感神经活性增高；④左侧RVLM及Ⅸ、Ⅹ颅神经REZ受压引起中枢RAS活性增加。

Objective We measured resistance index and pulsatility index of interlobar artery to detect the relationship of changes of allograft function with changes of interlobar artery RI and PI in renal transplantation recipients.

目的 运用彩色多普勒超声测量移植肾叶间动脉的阻力指数和搏动指数，观察两者的变化情况与肾功能变化的关系。

Methods RI and PI of main renal artery and interlobar artery were obtained by color Doppler ultrasonography within the first week of transplantation.Then they were correlated with allograft glumerular filtration rate at 1 year.

在100例无并发症肾移植患者中，应用彩色多普勒超声，于肾移植术后1周内，测量移植肾肾动脉和叶间动脉的阻力指数和搏动指数，并与术后1年的移植肾肾小球滤过率进行相关分析。

Abstract］ Objective We measured resistance index and pulsatile index of main renal artery and interlobar artery to detect whether they can predict 1 year allograft function in noncomplicated renal transplantation recipients.

目的 运用彩色多普勒超声早期测量肾动脉和叶间动脉的阻力指数和搏动指数，观察两者能否预测无明显并发症同种异体肾移植患者术后1年的肾功能。

These ratios include the S/D ratio, the Pourcelot index, and the pulsatility index see Fig.

这些比值包括S/D比值、Pourcelot指数和搏动指数（见图10-46和图10-47）。S/D比值是大脑中动脉的峰值流速除以大脑中动脉的舒张末期流速。

8 KPasBe subjected to another heart pulsates influence, the heart shoots blood into the artery and outside afferent resistance is germane for week, outside week the afferent resistance is more high, the artery blood pressure is also more high.

另外受心脏搏动影响，心脏射血进入动脉与外周血管阻力有密切关系，外周血管阻力越高，动脉血压也就越高。

An A-line is also inserted in patients who require numerous arterial blood gases in order to avoid repeated punctures.

动脉插管可以测量每一搏动的血压情况，它可以用于需要大量动脉血气的病人，避免重复穿刺。

The periodical changes is propagated along the arterial tree, arrive at radialis artery, and then can be detected.

心脏周期性搏动，将血液射入动脉管道，动脉管内的血压，血流量以及动脉管壁都随之发生一系列周期性的变化，这些变化传播到桡动脉处，可被诊知。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
