Role of vascular decongestion in ischemic acute renal failure defined by postinsult administration of pentoxifylline

Renal Failure
D R LukeR R Verani

Abstract

The patholophysiologic significance of vascular congestion in the mechanism of ischemic acute renal failure following postocclusive reflow was studied with a novel hemorheologic probe, pentoxifylline. Using the autoperfused rat kidney model, inulin clearances (CIN), urine flow rates (UFR), renal electrolyte excretions, and renal hemodynamic parameters (RVR, RBP, RBF) were compared in saline- and pentoxifylline-treated anesthetized rats prior to and following a 45-min occlusive period. Renal functional and hemodynamic parameters were significantly altered in saline controls. In contrast, postischemia treatment with pentoxifylline was associated with significant recovery in CIN and UFR, and stable RVR, RBF, and RBP. Kidneys treated with saline infusion had pronounced vascular congestion, in contrast to those administered pentoxifylline. Coupled with the absence in medullary hyperemia, the present experiments support the role of vascular congestion in ischemic acute renal failure. Pentoxifylline, administered in pharmacologic doses after the insult, provided benefit during the initiation phase of postischemic acute renal failure. These data strengthen the opinion that ischemic insult results in vascular congestion, and that restor...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
