  micro vessel
Seven fragments were synthesized taking the binding regions into consideration, but none showed any receptor binding affinity in cultures of bovine brain micro vessel endothelial cells (BMEC).
      
Bovine brain micro vessel endothelial cells have been isolated and grown in culture to monolayers.
      
Micro-vessel counts were carried out by an independent examiner using the following criteria.
      
Extract at nontoxic concentrations inhibited the production of micro vessel outgrowth from the rat aortic ring in vitro.
      
Arteriolar diameter was measured on-line by positioning two parallel lines on a micro vessel's image with the video micrometer.
      


A microprocessor-based dual-window video dimension analyzer for real time measuring changes in the diameter of micro vessels is recommended. These two windows could be adjusted to any location on the screen according to the direction of micro vessels. The circuit of this system converts the video output into the analog signal (voltage) proportional to the diameters being measured. The result can be recorded either analogously on a paper recorder or digitally on a displayer.

本文介绍用微处理器(单板机)及双窗口法实现对微血管直径的实时测量是。这两个窗口的位置可根据微血管的方向任意调节。本系统可把摄象机的视频信号转换成正比于所测微血管直径的模拟信号,结果既可记录在记录纸上也可用数字显示。

The effects of decreasing .blood viscosity through hemodilution on coronary collateral flow and myocardial injury in the.early phase of myocardial ischomia were studied in 21 open-chest anaesthetized dogs. It was shown that after 30 rain of coromary occlusion the low-shear viscosity of the whole blood (ηbl) began to increase gradually, while the collateral flow (CF) decreased concomitantly. At the 75-min postocclusion, ηbl increased by 18.1±3.9%, CF decreased by 24.1 ±4.6%, ST-segment of epicardial electrogram...

The effects of decreasing .blood viscosity through hemodilution on coronary collateral flow and myocardial injury in the.early phase of myocardial ischomia were studied in 21 open-chest anaesthetized dogs. It was shown that after 30 rain of coromary occlusion the low-shear viscosity of the whole blood (ηbl) began to increase gradually, while the collateral flow (CF) decreased concomitantly. At the 75-min postocclusion, ηbl increased by 18.1±3.9%, CF decreased by 24.1 ±4.6%, ST-segment of epicardial electrogram elevated significantly and the ultrastructural changes were characterized by severe mitochondrial damage, autolysis of myofilaments and blood cell obstruction in the micro vessel etc. In the hemodilution group, the chamges i1~ ~qbl and CF of the first 30-min postocclusion were quite the same as that of the control group. Following mild isovolemic hemodilution performed at the 30-min postocclusion, all of the ischemic changes improved significantly. At the 75-min postocclusion, contrary to the control group, ηbl decreased by 25.5±3.9% and CF increased by 54,7±10.8% as compared to the control value, the previously elevated ST segment decreased markedly and the ultrastructural injury alleviated to a great degree as well. The experimental results suggest that the deleterious hemorheologic changes in the early phase of myocardial ischemia is a major factor of aggravating ischemic myocardial injury and the decrese in blood viscosity through hemodilution may have protective effect on ischemic myocardium by increasing the collateral flow.

本实验在21只麻醉开胸狗身上观察了利用等容血液稀释降低血液粘度对心肌缺血早期冠脉侧支血流量与心肌损伤的影响。实验结果表明,阻断冠脉血流30分后,对照组低切变率下全血比粘度(η_(b1))逐渐增加,而侧支血流量(CF)则逐渐减少。缺血75分时,η_(b1)增加18.1±3.9%,CF减沙24.1±4%,心外膜电图ST段持续明显抬高,心肌超微结构显示线粒体破坏、肌原纤维自溶以及微血管内血细胞阻塞等损伤性变化。血液稀释组缺血30分时的各项指标与对照组均无明显差异,此时行轻度等容血液稀释后,上述各项指标均发生明显改善,缺血75分时,η_(b1)较对照值降低25.5±3.9%,CF增加54.7±10.8%,原已抬高的ST段发生显著降低,心肌超微结构的损伤性变化也明显减轻。上述结果提示,急性心肌缺血早期血液流变学的异常变化是加重心肌缺血性损伤的重要因索,而降低血液粘度以增加侧支血流量具有保护缺血心肌的作用。

Periodontal disease incidence in diabetics is higher than nondiabetes.Kron-man〔1〕(1970)suggested that increased blood vessel PAS-positive basement membrane area staining was noted to occur within 76.1% of the diabetic and 20% of the nondiabetic specimens evaluated.In this study,gingival micro-vessels from diabetic and nondiabetic sufferingswere examined by light and eletron microscopes.Pronounced changes and thickening of vessel walls were found in diabetic gingival micro-vessels,and,in many cases,swelling of endothelial cells produced lumenal obstruction.Plasma ceils in gingival tissue presented prominent feature degeneration and,occasioanlly,Russell bodies were observed.
