white blood cells to the site.Complement activationmay also be involved in the production ofkinins(active polypeptides increasing the calibre and the permeability of blood vessels) and possibly also in the release of histamine. Components C′1 to C′3 help to promotephagocytosis, acting as opson...
PURPOSE: A single image blood vessel diagram calculator using observation time difference correction is provided to model blood vessels by correcting a blood vessel diagram according to the position of an observer.;CONSTITUTION: Two kinds of spaces such as concave shape and a convex shape are ...

Interesting, all patients suffering from ICH may be considered as having a blood sta- sis syndrome according to the TCM theory of 'the blood flow outside the vessels is the blood stasis'; this also takes advan- tage of the utility of a CT scan or MRI in the diagnosis of ICH. Thus, ...

2 It is thought that a diffuse arteriopathy of the cerebral small vessels results in hypoperfusion and impaired cerebral autoregulation, with subsequent ischemia leading to white matter hyperintensities (WMHs) visible on T2-weighted magnetic resonance imaging (MRI), as well as lacunar infarction.2 ...
A transcutaneous system and method for real time imaging of blood vessels. The system includes a transducer having one or more arrays of transducer elements for scanning across or along blood vessels.
I LEFT A diagram to show the position of the feeding vessels to the anterior spinal artery in 22 spinal cords. This gives the frequency of such vessels on each ventral root; the great spinal arteries being indicated by the thick line. entering on the right or left sides is about equal ...
The blood–retinal barrier is maintained by tight junctions that exist between the endothelial cells of theretinal vesselsand similar tight junctions in theRPE(seepp. 254–258). Thus, the retinal vessels and the RPE are impermeable to the passage of molecules greater than 20 000–30 000...
has been clearly shown to be the preferred modality for diagnosing narrowing or stenosis in vessels. In the one case where projection NMR imaging has been considered, as in the system of the first paper cited, the intervening tissue would seriously reduce the effectiveness of the image. In addi...
