Morphological study on postcapillary venule of human dermal cancer 人皮肤癌毛细血管后微静脉的形态学研究
Venous system in right ventricle wall was similar in architecture to that in left ventricle, postcapillary venule joined its corresponding venule in a "turnip root" like pattern. 室壁静脉构筑与左室相似,亦见到毛细血管后微静脉以萝卜根样形式汇入微静脉。
The femoral artery and venule group was grade I imaging. 支动脉和小静脉组为I级显像;
Methods: Experiments were designed with the three element two level orthogonal method and microcirculatory microscope and other devices were used to test the diameter of the capillary vessel and the venule of the experimental group in the simulated shipboard environment and the control group. 方法:采用三因素二水平正交方法[L8(27)]设计实验,以微循环显微镜和照相裂隙灯显微镜检测8次实验的暴露组与对照组兔球结膜毛细血管和微静脉管径。
It can expand the caliber of arteriole and venule, increase the open numbers of capillary vessel, prolong the bleeding and clotting time and reduce length and weight of rat's thrombus; 能扩张小鼠耳廓微动、静脉管径,增加毛细血管开放数,延长小鼠出、凝血时间,降低血栓长度和重量;
Methods: The model of leukocytes adhesion and microcirculatory hindrance were made by injection endotoxin in venule in rats. 方法:静脉内注入内毒素造成白细胞粘附和微循环障碍模型,通过肠系膜微循环观察。
Y-27632 did not influence Pa value in normal venule. However, it significantly attenuated the hyperpermeability responses to scalding in a dose and time dependent fashion. Y-27632对正常皮肤微静脉Pa值无明显影响,但使经烫伤后增高的皮肤微静脉通透性降低,呈现剂量和时间效应。
The results suggest that electret treatment have beneficial effects on regulating arteriole and venule tension, preventing thrombosis and improving microcirculation. 提示驻极体治疗具有调整细小动脉和静脉张力,防止血栓形成和改善微循环的作用。
Experimental study and clinical application of venule autograft in digital replantation 断指再植中自体小静脉移植的实验研究和临床应用
The diameter of yak's venule, which was composed of several capillaries from different arterioles sources, was less than 300 μ m, and the typical characteristic of the venule was tree root-like pattern. 牦牛微静脉的直径小于300μm,呈树根样结构。一条微静脉由若干条不同来源的毛细血管结合而成。
Objective To evaluate the success rate of bridging defects of venule and arteriole by venule ( 1mm in diameter) autograft in digital replantation. 目的研究用外径1mm左右的自体小静脉移植修复小动脉和小静脉缺损在断指再植中的成功率。
