Quantitative assessment of the microcirculatory
parameters was accomplished off-line by frame-to-frame analysis of the videotaped images.
DM can cause microvascular injuries and other microcirculatory
disorders including unexpected increment of blood viscosity and thrombotic and embolic events .
This finding suggests that the noted depression of cerebral rS[O.sub.2] is not due exclusively to vasospasm but perhaps a direct result of global microcirculatory
vasoconstriction induced by vasopressors.
Coronary flow reserve and microcirculatory
resistance in patients with intermediate coronary stenosis.
factor(s), Factors VIII and I, microcirculatory
abnormality, and platelet malfunction" (5).
Though recent histological reports support T1 shortening due to increased cytoplasmic protein content within reactive gemistocytic astrocytes, likely precipitated by hyperosmolar injury and potential microcirculatory
hyperviscosity, other cofactors would likely underlie the density changes on CT.
It is only in the case of chronic disease, in particular, diabetes, with its well-known microcirculatory
pathology, that MIs start to show up.
They result in the sequestration of RBCs containing mature forms of the parasite in vital organs (particularly the brain), where they interfere with microcirculatory
flow and metabolism.
We first measured the stability and repeatability of the perfusion parameters of CEUS perfusion imaging and then assessed quantitatively the hepatic microcirculatory
function using a variety of mathematical function models by applying harmonic imaging techniques, intermittent power Doppler imaging, and grayscale CEUS.
The possible pathogenic mechanism of this disease is still not well established, but is thought to be associated with a high level of catecholamine during extreme stress, and it causes coronary vasospasm and cardiac microcirculatory
"Microvascular dysfunction and peripheral vasoconstriction with mental stress are implicated in MSIMI among women but not among men, perhaps reflecting women's proclivity toward ischemia because of microcirculatory
abnormalities," the authors write.
Blood biochemistry, hemodynamics, sublingual microcirculation including perfused small vessel density (PVD) and microcirculatory
flow index (MFI), and histopathological changes in major organs including the lung, kidney, liver, and heart were compared between subgroups.
