Hemodynamics at stenoses formed by growing platelet thrombi in mesenteric microvasculature of XXXX .

@entity35 @entity715 @entity850 @entity1423
Quantitative analyses of the dynamics of @entity850 development were expressed in terms of the time course for changes in blood flow velocity in a stenosed region and @entity715 configuration in the microvasculature of @entity35 mesentery. The @entity1423 was induced in microvessels by irradiation of filtered light in combination with intravascular administration of fluorescent dye. The blood flow velocity began to increase soon after the initiation of @entity715 formation and continued to increase progressively with the growth of the @entity715 in the radial direction. After the velocity reached an almost constant level, the velocity fluctuation became significant due to the frequent @entity1423 . Meanwhile, the blood flow velocity precipitously dropped. Two different definitions of a critical @entity850 were proposed. The first definition was the condition that the blood flow velocity reached a maximum. The critical area @entity850 based on this definition had almost a constant value, i.e., 75-95% of the lumen area. The second definition of critical @entity850 was given as the condition that the blood flow rate decreased by more than 15%. In the higher velocity range the values of critical @entity850 based on the second definition were almost constant, i.e., 70-90% of the lumen area. However, in the lower velocity range, the critical condition seemed to occur in smaller @entity850 .
