Introduction The renal arteries arise from abdominal aorta below the origin of superior mesenteric artery, on each side. Near the hilum of the kidney, each renal artery divides into anterior and posterior branch, which in turn divides into number of segmental arteries supplying the different renal segments. The presence of unusual branching patterns of the renal arteries is not uncommon. In 70%...

branches of the abdominal aorta. A single renal artery supplies each kidney in most individuals. The renal arteries typically arise just below the origin site of the superior mesenteric artery and they travel laterally behind the renal veins (1, 2). Among the various types of renal artery anomalies, the most clinically important variation is the accessory renal artery. Accessory renal arteries ...

we investigated contraction to noradrenaline (na) and kc1 and sensitivity of na at the level of larger vessels (thoracic aorta and vena cava; left renal artery and left renal vein; lateral saphenous artery and lateral saphenous vein and finally central ear artery and marginal ear vein) in a model devised to mimic heart failure. the model presented here is the rabbit coronary ligation model in w...

UNLABELLED We report a case of an unsual anatomical vascular blood supply to the right kidney. In an analysis of kidneys, by dissection of 39 foetuses, additional renal arteries were found in 18 cases (46.15%). In only one case (2.5%) was it noticed that the right kidney was supplied with blood by three renal arteries, one main and two additional arteries. One of the additional arteries, marked...

BACKGROUND Plasma levels of endogenous guanidine compounds are increased in various pathologic conditions, including chronic renal failure. In the present study we tested the effects of some of these compounds on basal and stimulated nitric oxide activity in human renal arteries. METHODS Rings from human renal arteries were obtained from 22 patients undergoing nephrectomy. The rings were susp...

For many years, it has been accepted that derangement of kidney function is intimately related to hypertension. Fishberg (1), de Wesselow (2) and Volhard (3) have pointed out that, with the exception of amyloid degeneration of the kidneys, severe kidney derangement is consistently accompanied by hypertension. The frequent absence of hypertension in amyloid involvement of the kidney has been sup...

Responses to K(+), endothelin-1 (ET-1), and acetylcholine (ACh) of isolated adrenal, femoral, middle cerebral, and renal arteries from fetal [110--145 days gestational age (dGA, term approximately 148 dGA)] and 0- to 24-h newborn (NB) lambs were evaluated using the technique of wire myography. Responses at distinct developmental ages for each vascular bed were compared. In all arteries sensitiv...

introduction: vertebral arteries arise from the root of the neck as the first branches from the superior-posterior aspect of the subclavian arteries. they ascend the neck to enter the cranial cavity and supply blood to the brain. methods: a total of 20 cadavers (in 10 years) were dissected for the study of variations in the origin of the vertebral artery. this study was conducted in isfahan uni...

there are often duplicated ureter with types of congenital anomalies and associated clinical complications. the unilateral duplicated ureter was observed as an incidence result in usual dissection. during routine dissection of the body of an adult male with middle-aged 40-50 year old, the duality of unilateral incompletely ureter was seen in above. two branches of ureter are coalesce in 7 cm di...
