The basic functional unit of the liver is the hepatic lobule, which consists of portal triads (hepatic arteriole
, portal venule, bile duct, lymphatics and branch of the vagal nerve) at the periphery that surround a central vein (Fig.
Intraluminal microthrombi are defined by the presence of thrombi with or without organization, occluding at least 1 capillary or small arteriole
in the LP and/or submucosa (Figure 6, A and B).
He walks readers through optic disk size and shape; optic cup shape and depth; optic cup size in relation to the optic disc size; neuroretinal rim size, shape and perfusion; central retinal vessel trunk location; optic disc hemorrhages; parapapillary chorioretinal atrophy; retinal arteriole
diameter; and retinal nerve fiber layer defects.
These lesions typically appear round or oval in shape and adjacent to a retinal arteriole
In the active stage, BRAO is best assessed by fundus fluorescein angiography (FFA), in which it typically appears as multifocal fluorescence in the arteriole
This is secondary to renal vasoconstriction of the afferent arteriole
12 Previous studies demonstrate that, main causes for hypertensive cerebral hemorrhage include micro-aneurysm formed in cerebral arteriole
at basal ganglion, weakened structure of external membrane and middle-layer membrane of cerebral arterial wall, spasm of cerebral arteriole
induced by high blood pressure and fibrinoid necrosis of cerebral arteriole
induced by high blood pressure.
Both sildenafil and MB200 intervention attenuated the monocrotaline-induced arteriole
remodelling resulting in significant reduction in the medial wall thickness.
Results: Diabetes caused significant histomorphological changes in arteriole
of kidneys of Experimental Group B compared to Control Group A (pgreater than 0.
Although the general arrangement of blood vessels in both circulations is from arteries to capillaries to veins, in some parts of the systemic circulation it is modified so that a vein or an arteriole
is interposed between two capillary networks; these vessels constitute portal systems.
In the kidney, it causes strong vasoconstriction of the efferent arteriole
and moderate vasoconstriction of the afferent arteriole
, directly stimulates the reabsorption of sodium ions in the proximal tubule, thereby contributing to an increased volume of extracellular fluid and the development of hypertension [1,2].
Ocular blood velocity data were obtained from retinal and choroidal vasculature (RCV), superior temporal retinal arteriole
(STRA), and superior nasal retinal arteriole
