Results The pial microarteries contracted in line during initial ischemia.

结果脑缺血初期，细动脉呈线状收缩。

ABSTRACT AIM: To study the effects of dl-, l- and d-3-n-butylphthalide on pial arteriole diameter and blood flow velocity in focal ischemia rats. METHODS: Urethane-anesthetized rats were instrumented for monitoring pial AD and BFV in the cranial window preparation.

经多年研究表明，本室研制开发的一类新型抗脑缺血药物丁基苯酞，有调节脑缺血状态下脑能量代谢［1］、增加缺血区脑血流量［2］、缩小脑梗塞面积、减轻脑水肿［3］、改善脑缺血后神经功能缺损症状的作用。

At 24 h after reperfusion, TSA (100 and 200 mg·kg-1) was shown to possess the ability to inhibit the increased plasmic serotonin, TXB2 concentrations, and brain MPO activity induced by focal cerebral ischemia-reperfusion.

TSA(100和200 mg·kg-1)可显著抑制缺血90 min再灌注24 h时血浆5-HT和TXB2含量及脑MPO活性增高。

The myocardial ischemia reperfusion injury is the myo- cardial tissue injury when myocardium is reperfused with the pleonectic blood in the condition of anoxia or blood deficit.

心肌缺血再灌注损伤系心肌组织在缺血或缺氧情况下进行有氧再灌注时产生的损害。

Results CT shows 18 cases of mesenteric edema, 2 cases of mesenteric pneumatosis, 7 cases of mesenteric vascular anomalies, 5 cases of mesenteric vascular were filling defect, 2 cases of the trunk of the mesenteric vascular were thickening, 21 cases of segmental mesenteric small blood vessels hyperemia, 7 cases of segmental mesenteric small blood vessels ischemia and 2 cases of the mesenteric venous accumulation of gas.

结果 CT表现：肠系膜水肿18例，肠系膜积气2例，肠系膜血管走行异常7例，肠系膜血管充盈缺损5例，肠系膜主干血管增粗2例，节段性肠系膜小血管充血21例，节段性肠系膜小血管缺血7例，肠系膜静脉积气2例。

Pneumatosis intestinalis and portomesenteric venous gas are alarming radiological findings that signify bowel ischemia. The management of PI and PMVG remain a challenging task because clinicians must balance the potential morbidity associated with unnecessary surgery with inevitable mortality if the necrotic bowel is not resected.

肠气囊肿病和门脉肠系静脉积气在影像诊断学上是缺血性肠道疾病非常重要的表现，当病人的影像出现肠气囊肿病或是门脉肠系静脉积气时，临床医师要如何作最适当的处置，依然是一项富挑战性任务，因为如果坏死的肠组织没有被切除，无可避免的会造成病人死亡，但是多余的手术亦会有潜在的并发症。

AIM: To determine the effects of posthepatic manipulative bleeding on the lung injury induced by hepatic ischemia-reperfusionin rat model.

目的： 探讨肝后控制性失血处理对肝脏缺血再灌注所致肺损伤的影响。

AIM: To determine the time course and peak production of reactive oxygen species in suprahepatic vena cava after hepatic ischemia-reperfusion and to study the effects of posthepatic manipulative bleeding on HIR injury in rat model.

目的：确定肝脏缺血再灌注时肝上下腔静脉血中氧自由基产生的时相及峰值，探讨SH-VC控制性失血处理对HIR损伤的影响。

METHODS: Rat 35 min total hepatic ischemia model was used in this study. We treated the experimental rats by posthepatic manipulative bleeding or IH-CV manipulative bleeding at 10 min after reperfusion.

用大鼠HIR损伤模型，在再灌注后的10min分别在肝上下腔静脉及肝下下腔静脉进行控制性失血处理，观察其对HIR所致肺损伤的影响。

Objective: To investigate the diagnostic value of postsystolic shortening for ischemia during adenosine stress echocardiography in animal models.

目的：探讨收缩期后收缩在腺苷负荷试验中诊断早期心肌缺血的价值。

However it can often be frust ating for a child when people are unable to pronounce their name.

但它往往可以令人沮丧的一个孩子当人们无法断言他们的名字。

All these compounds were obtained from this genus for the first time. Compound, 4-cumylphenol, was a new nature product.

所有化合物均为首次从本属海藻中分离得到，其中4cumylphenol为新天然产物。
