vasodilator of postcapillary
venules which cause increased vascular permeability in postcapillary
venules, leading to protein extravasation (tissue edema)
Together, the arterioles, associated capillary network, and postcapillary
venules form a functional unit called the microcirculatory or microvascular bed of that tissue.
Nitric oxide is an upstream signal of vascular endothelial growth factor-induced extracellularsignal-regulated kinase 1/2 activation in postcapillary
It involves the small blood vessels and postcapillary
The pre-exercise parameters (condition "pre-exercise") venous oxygen saturation (SO2), postcapillary
venous filling pressures (rHb) and microcirculatory blood flow (flow) were measured at two distinct tissue depths (2 mm and 8 mm) after resting 10 minutes on the ergometer bicycle.
Increased permeability results mainly from actions of histamine on postcapillary
venules, where histamine causes the endothelial cells to contract and separate at their boundaries (Goodman-Gilman 1990).
This swelling condition is a result of interstitial edema from vasoactive mediators increasing the permeability of postcapillary
venules of the subcutaneous and submucosal tissues.
In Type III reaction, complexes formed by the drug or its metabolite and specific IgG and IgM antibodies developed against these are deposited in postcapillary
Another notable feature is the use of a simple off-the-shelf tube that is the size (300 [micro]m) and shape of postcapillary
venules where endothelial cells are stimulated by inflammatory stimuli.
The measurement depth of the LDF reaches to the arterioles, capillaries, and postcapillary
venules of the upper horizontal plexus but does not extend to the deep horizontal plexus .
Amazingly, he demonstrated that nothing happened in the capillaries but that there was separation of the endothelial cells in postcapillary
venules, which was the pathogenesis of the vascular leak; this totally unexpected observation is widely regarded as one of the major discoveries in experimental vascular pathology.
Hemangiopericytoma is an uncommon hypervascular mesenchymal neoplasm originating from modified contractile smooth-muscle cells that surround capillaries and postcapillary
venules, called pericytes of Zimmerman.
