A method for combined perfusion and microscopic studies in viable vascular bed of the rat mesoappendix was presented. Observations are described showing that the gradient reactivity of the smallest structural commitment of the vascular bed can also be observed in isolated perfused tissues. This suggests that this gradient of vascular response is inherent in smooth muscle and independent of extrinsic influences. When the distending influence of the internal pressure is reduced, the vessel regularly shows constriction or complete occlusion. This closure is independent of the sensitivity gradient.

    The microvascular flow index (MFI) is commonly used to semiquantitatively characterize the velocity of microcirculatory perfusion as absent (0), intermittent (1), sluggish (2), or normal (3). There are three approaches to computeMFI: (1) the average of the predominant flow in each of the four...

    F-FDG-PET is increasingly used to assess pulmonary inflammatory cell activity. However, current models of pulmonary F-FDG kinetics do not account for delays in F-FDG transport between the plasma sampling site and the lungs. We developed a three-compartment model of F-FDG kinetics that includes a...

    To study the process of O2 transport to tissue, we investigated how capillary perfusion is controlled in response to changes in tissue O2 levels in skeletal muscle. Capillary red blood cell (RBC) velocity and perfused capillary recruitment were measured in rabbit tenuissimus muscle at various...
