Preservation of normal cortical vasculature in ischaemic renal failure in the dog. 1976

J Best, and J P Lavender, and S Russell, and T Sherwood

Ischaemic renal failure in the dog was studied by clamping one renal artery for 2 hr in 18 animals. Total renal blood flow was measured for 3 hr after this and only reduced by about 30%. Fine detail renal angiography showed a normal cortical perfusion pattern. Urine flow rates and creatinine clearances from these kidneys, however, were found to be grossly impaired over this period. Seven days later the angiogram of the oliguric kidney remained normal. Two-hour unilateral renal ischaemia in the dog leads to a form of acute renal failure with a striking disparity between glomerular perfusion and clearance, arguing agains a primary circulatory defect.

UI	MeSH Term	Description	Entries
D007511	Ischemia	A hypoperfusion of the BLOOD through an organ or tissue caused by a PATHOLOGIC CONSTRICTION or obstruction of its BLOOD VESSELS, or an absence of BLOOD CIRCULATION.	Ischemias
D007668	Kidney	Body organ that filters blood for the secretion of URINE and that regulates ion concentrations.	Kidneys
D007672	Kidney Cortex	The outer zone of the KIDNEY, beneath the capsule, consisting of KIDNEY GLOMERULUS; KIDNEY TUBULES, DISTAL; and KIDNEY TUBULES, PROXIMAL.	Cortex, Kidney
D009846	Oliguria	Decreased URINE output that is below the normal range. Oliguria can be defined as urine output of less than or equal to 0.5 or 1 ml/kg/hr depending on the age.	Oligurias
D012078	Renal Artery Obstruction	Narrowing or occlusion of the RENAL ARTERY or arteries. It is due usually to ATHEROSCLEROSIS; FIBROMUSCULAR DYSPLASIA; THROMBOSIS; EMBOLISM, or external pressure. The reduced renal perfusion can lead to renovascular hypertension (HYPERTENSION, RENOVASCULAR).

D004285	Dogs	The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065)	Canis familiaris,Dog
D005919	Glomerular Filtration Rate	The volume of water filtered out of plasma through glomerular capillary walls into Bowman's capsules per unit of time. It is considered to be equivalent to INULIN clearance.	Filtration Rate, Glomerular,Filtration Rates, Glomerular,Glomerular Filtration Rates,Rate, Glomerular Filtration,Rates, Glomerular Filtration

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
