您要查找的是不是：
- precapillary arteriole 毛细血管前小动脉
- precapillary arterioles 毛细管前小动脉
- Microcirculation is the blood circulation between arteriole and veinule. 微循环是指微动脉和微静脉之间的血液循环。
- One form, called hyaline arteriolosclerosis, is demonstrated by the markedly thickened arteriole to the lower right of this glomerulus with PAS stain. 经过PAS染色，可见连接右下方肾小球的细动脉已明显变厚，它就是被称为玻璃样变细动脉硬化的一种形态。
- The results showed that each intestinal villi had only one spiral villi arteriole coming from the tunica submucosa. 结果表明:1大鼠小肠绒毛有一条来自粘膜下层的螺旋形的绒毛微动脉;
- The arteriole here has an "onion skin" appearance typical of hyperplastic arteriolosclerosis. 细动脉呈“洋葱皮”外观，这是增生性细动脉硬化的典型表现。
- Results The results showed that the microvessls dilated, but the effects were more obvious in venule than in arteriole. 10例急性心肌梗塞服用尼可地尔后，肺楔嵌压下降，心输出量增加，微血管扩张。
- Indeed, efforts to tease out the source of arteriole malfunction led us to our unexpected discovery six years ago. 果然没错，为厘清微动脉机能障碍源头所付出的心血，造就了我们六年前的意外发现。
- The main pathological changes of PAH are vasoconstriction and arteriole organization afterward. 而缺氧性肺血管收缩及小动脉机化是其主要病理变化。
- In Group B,the observation under optical microscope showed vitreous degeneration of retinal central arte- riole,kidney arteriole and spleen arteriole. A 组视网膜、肾脏、脾脏血管形态和组织结构正常,B 组小动脉壁呈均质玻璃样变性,C 组血管结构基本正常。
- Significance: hypoxic perialveolar arteriole contracts, more blood flows through sufficient ventilation alveolar and carries on effective gas exchange. 意义:氧分压低的肺泡周围微动脉收缩;较多的血液流经通气充足的肺泡进行有效的气体交换.
- One complication of hyperplastic arteriolosclerosis with malignant hypertension is fibrinoid necrosis, as seen here in a renal arteriole. 恶性高血压伴增生性小动脉硬化的并发症之一是细动脉纤维素样坏死,正如图中所示肾动脉的表现。
- Thickening of the arterial wall with malignant hypertension also produces a hyperplastic arteriolitis. The arteriole has an "onion skin" appearance. 恶性高血压引起的动脉壁增厚发生增生性小动脉炎，小动脉呈洋葱皮样表现。
- In the other two cases of the coronary arteriovenous fistulas, it is defined as a direct precapillary anastomosis between a majar coronary artery and the pulmonary trunk or the left ventricle. 2例冠状动静脉瘘，显示冠状动脉和肺动脉干与左室之间，存在毛细血管前吻合。
- The glomerulus here stained with PAS shows nodular deposits of amorphous material (nodular glomerulosclerosis) along with a thickened arteriole at the lower right. 这个PAS染色的肾小球可见右下角处的增厚的细动脉管壁有无定形的物质沉积。
- MethodsThe blood vessel model w as made and the supply in the finger tip by tip back arteriole was studied unde r the surgical microscope and scan electronic microscope. 方法制作血管铸型标本、手术显微镜及扫描电镜观测等方法研究指端背动脉的血供。
- This is the normal histologic appearance of the spleen.Note the small lymphocytes centered around the splenic arteriole at the center, forming the white pulp. 正常脾的组织学外观，可见小淋巴细胞围绕在中央的脾小动脉周围，形成白髓。
- The blood volume of microcirculation is in direct proportion to the dp of arteriole and veinule,and in inverse proportion to the whole resistance of microcirculation. 微循环的血流量与微动脉和微静脉之间的血压差成正比;与微循环中血流总阻力成反比.
- The velocity and flux of red blood cell (RBC) in villus tip arteriole and capillaries were measured by FITC-labeled erythrocytes and intravital microscopy. 利用FITC标记红细胞和活体显微镜方法直接观测并计算小鼠小肠绒毛尖端小动脉和毛细血管内红细胞的流速和流量。
- Note also the markedly thickened arteriole at the lower right which is typical for the hyaline arteriolosclerosis that is seen in diabetic kidneys as well. 图右下的小动脉管壁显著增厚，是糖尿病肾病的玻璃样变性的小动脉的典型表现。
