Leukocyte-endothelium adhesion: Microhemodynamics in mesentery of the cat
Microvascular Research, 1987The effects of leukocyte-endothelium adhesion on microhemodynamics were studied in cat mesentery under control conditions and following tissue suffusion with the chemotactic agent N-formyl-methionyl-leucyl-phenylalanine (FMLP). The results indicate that under normophysiological conditions there is little or no leukocyte-endothelium adhesion in ...

Imaging of Microhemodynamics in Peripheral Nerves by Contact Endoscope
World Neurosurgery, 2019Entrapment neuropathies include a wide field of locations. In most cases, the microsurgical decompression is still the therapy of choice. However, the role of venous stasis and ischemia is still discussed controversially. Here the authors evaluated the visualization of microvessels and the microperfusion at peripheral nerves with a contact endoscope ...

Speckle-correlation monitoring of the microhemodynamics of internal organs
Optics and Spectroscopy (English Translation of Optika I Spektroskopiya), 2009The results of preliminary experimental studies of the possibility of monitoring blood microcirculation in surface layers of internal organs of laboratory animals in the course of laparotomy using full-field speckle correlometry are presented. The transmission of laser radiation to the probed part of the organ and the delivery of scattered speckle ...

Effects of ketanserin on microhemodynamics and hemorheology in patients with essential hypertension
Cardiovascular Drugs and Therapy, 1990Ketanserin, a serotonin antagonist, has recently been developed. This agent produces antihemagglutination and dilation of blood vessels. Blood pressure is also lowered by ketanserin. We investigated the effect of ketanserin on microhemodynamics and hemorheology in essential hypertension. Twenty patients with essential hypertension (8 males; 12 females;

Microhemodynamics of capillary networks
Biorheology, 1981The single-file flow of red blood cells in microcirculatory networks is studied theoretically. A phase-separation rule for the cells at the bifurcations is established and the flow-pressure drop relationship for the individual flexible cells is obtained from the work of Sutera and co-workers [Capillary blood flow. II.

Microhemodynamics of retinal collateral vessel formation
Medical Hypotheses, 1995Retinal collaterals are a common clinical occurrence after branch vascular occlusions in humans and laboratory animals, yet the etiology and functional significance of these vessels is uncertain. A hypothesis is presented which attempts to explain the difficult problem of retinal arterial collateral circulation.

Volume replacement and microhemodynamic changes in polytrauma
Langenbeck's Archives of Surgery, 2004Though fluid administration is one of the most basic concepts in resuscitation, there is ongoing controversy and continuing research on the definition of the ideal fluid for resuscitation of trauma and hemorrhage and for intraoperative volume support.

Effect of FTY720 Treatment on Postischemic Pancreatic Microhemodynamics
Transplantation Proceedings, 2010CD4+ T cells contribute to disturbances of pancreatic microcirculation after cold and even after warm ischemia/reperfusion (I/R). The aim of this study was to investigate a possible protective role of FTY720 (fingolimod) in this setting. In an in vivo model (42 Wistar rats), ischemia of the pancreas was induced for 60 minutes under anesthesia with ...

Computer Simulation of Cerebral Microhemodynamics
1989Microvascular network hemodynamics was simulated by computer in an anatomically reconstructed cerebral microvascular network. A video microscope system was used for three-dimensional mapping of the vessel network in the rat brain cortex. The complete topology, length and mean diameter of the microvessels were determined.

Endothelin-A Receptor Blockade Improves Postischemic Hepatic Microhemodynamics
Journal of Cardiovascular Pharmacology, 2004The aim of this study was to investigate a possible protective role of a selective endothelin-A receptor antagonist on hepatic microcirculation after ischemia/reperfusion. In a rat model, warm ischemia of the left liver lobe was induced for 90 minutes under intraperitoneal anesthesia with xylazine and ketamine.
