Using microperfused isolated bile duct units preloaded with the calcium sensitive dye, flu4, we observed that a decrease in perfusate tonicity increased [Ca2+]i by 45%; treatment of IBDUs with the deciliiating agent, chloral hydrate, or a TRPV4-siRNA abolished this effect.

结果47例肝脏灌注异常，有以下几种情况：肝动脉门静脉瘘9例，炎症性充血8例，门静脉、肝静脉阻塞13例，肿瘤盗血现象4例，肝脏迷走血供2例和其它原因1例。结论多层螺旋CT三期增强扫描是评价肝脏异常灌注的有效方法。

Systolic perfusion or diastolic perfusion was calculated bydividing the subendocardial intensity at systole or diastole,respectively,for each segmentby the mean value across all segments for each patient.T-test was used for the statistics.

DSCT冠脉成像作为心肌灌注的定性评估方法，在兼顾冠脉成像和心功能分析的基础上，能初步评价心肌首过灌注及其时相和节段的变化，为进一步评价缺血性心脏病提供参考。

Several investigators have determined that placing the electrode parallel rather than perpendicular to the target nerve substantially increases the size of the lesion, thereby reducing the likelihood the treatment will miss or only partially coagulate the target nerve.234,235 After a literature review and cadaveric study, Lau et al.234 concluded the ideal electrode position is across the lateral neck of the superior articular process rather than the groove formed at the angle of the superior articular and transverse processes, as was used in most studies.159,160Other investigators have found the maximal lesion size to be reached within 60 s of lesion time,235–237 independent of whether the system is temperature or voltage controlled.238 Studies conducted in human myocardium have determined that irrigation fluid has either no effect or a slightly beneficial effect on lesion size.239 Hence, the use of LA to prevent procedure-related pain or steroid to reduce the incidence of neuritis184 should theoretically have no adverse effects on the efficacy of radiofrequency denervation.

一些研究者认为，将点击平行的置于目标神经比将其垂直置于目标神经增加了消融的范围，因而减少损伤可能使目标神经不被或部分被消融。Lau等回顾了文献中对尸体的研究，总结出理想的电极放置位置为上关节突颈部外侧而非常采用的上关节突与横突形成的沟。其他学者研究发现，不论系统是温度控制或电压控制，其最大的损伤范围都在60秒内达到。在心肌灌注的研究中，灌注液多损伤范围造成轻微或不造成损伤。因此，使用LA预防过程相关性疼痛或类固醇防止神经炎发生时，需理论上确保对射频消融效果无副作用。

HSPT was induced by perfusing isolated hearts with 42℃ cardioplegic solution for 15 minutes.

使用42℃高温停搏液灌注离体鼠心15min对缺血/再灌注的心脏作HSPT。

Perfusion in the right parietal lobe in group2 was significantly lower than in group1 (P.01).（2）Average perfusions were higher in the right temporal and parietal lobes than in the left in all 3 groups.（3）Gray matter volumes were significantly smaller in group3 than in group2 (P.05); total cerebral spinal fluidsvolumes were significantly larger in group3 than in group1 and group2（P.05）; right hippocampus volumes were significantly smaller in group3 than in group1 （P.05）. Conclusions Age-related change of cerebral blood perfusions in the healthy elderly over 65 years is characterized with hypoperfusion in the right parietal.

结果（1）经方差分析，第2组和第3组脑组织几乎所有部位的灌注均低于第1组，其中第2组右顶叶灌注的放射性计数比值为0.87±0.18，低于第1组（RAR=0.98±0.17；P.01）；（2）经配对t检验，除第2组的双侧顶叶外，3组颞叶和顶叶的灌注均为右侧高于左侧（P.01和0.05）；（3）经方差分析，第3组的灰质体积占颅内容积的百分比［（47.59±1.26）%］小于第2组［（49.43±1.30）%］，总脑脊液体积占颅内容积的百分比［（14.61±3.16）%］大于第1组［（12.41±0.73）%］和第2组［（11.94±1.27）%］，右侧海马体积［（2.04±0.23）cm3］小于第1组［（2.27±0.20）cm3］，P均。05。
