In histopathological evaluations, lymphocytic infiltrations forming lymphoid follicles and within the follicles eosinophils, vascular proliferation, dense endothelial venules and fibrosis were observed (1,4,9).

(2007) Plasmacytoid dendritic cells employ multiple cell adhesion molecules sequentially to interact with high endothelial venule cells--molecular basis of their trafficking to lymph nodes.
Cryobiopsies are reported to yield significantly larger specimens with more alveoli, bronchioles, veins, and venules, and less procedure-related artifact when compared to traditional forceps transbronchial biopsies (Figure 1, A and B).
Similar to ischemic brain injury we reviewed above, all of these pathophysiological factors could directly and indirectly cause cerebral venule endothelial dysfunction, microthrombus, and eventually outflow reduction.

Pathophysiological changes may include BBB damage, hypoperfusion, venule collagenosis, cerebral blood flow autoregulation impairment, and endothelial cell dysfunction [43, 45-47].
Light microscopic examination of livers of control rats showed normal lobulation with clear outlines, normal Kupffer cells with distinct cell boundaries and clearly visible nuclei, no infiltration of central venules by leukocytes, and lack of mitotic figures (Figure 2(a)).
Vessel diameter summary was also measured using IVAN software (University of Wisconsin, Madison, WI, USA) based on the calibre summary of the biggest 6 arterioles and venules separately and vessel summary represented by Central Retinal Arteriolar Equivalent (CRAE) and Central Retinal Venular Equivalent (CRVE) [23] as well as the ratio of the calibre of arterioles to venules (AVR).
The natural history accounts for an incidence of 2-3% of all primary meningeal tumors [4], and they are believed to arise from Zimmerman pericytes, small muscular cells lining capillary and postcapillary venule walls [1].
where [W.sub.c] is the calibre of the trunk venule, [W.sub.a] is the calibre of the smaller branch venule and [W.sub.b] is the calibre of the larger branch venule.
