Effect of renal nerve stimulation on the activity of the tubuloglomerular feedback mechanism. 1984

K Hermansson, and O Källskog, and M Wolgast

The influence of renal nerve stimulation on the tubuloglomerular feedback mechanism was studied on anaesthetized rats. The analyses was made by comparing the single-glomerular filtration rate (SNGFR) measured from late proximal tubules with SNGFR measured from distal tubules in the same nephron. In the former situation the flow to the macula densa cells is interrupted and in the latter the macula densa is influenced by the flow passing by. In the control situation the SNGFR measured proximally was 47.7 +/- 2.2 nl . min-1 (mean +/- SE) and 40.1 +/- 1.8 measured distally indicating an activated tubuloglomerular feedback. During renal nerve stimulation (2-3 Hz), the SNGFR fell to 38.5 +/- 2.3 and 33.5 4/- 1.7 when measured proximally and distally, respectively. The results indicate that the tubuloglomerular feedback mechanism is unaffected by renal nerve stimulation.

UI MeSH Term Description Entries
D007668 Kidney Body organ that filters blood for the secretion of URINE and that regulates ion concentrations. Kidneys
D007678 Kidney Glomerulus A cluster of convoluted capillaries beginning at each nephric tubule in the kidney and held together by connective tissue. Glomerulus, Kidney
D007684 Kidney Tubules Long convoluted tubules in the nephrons. They collect filtrate from blood passing through the KIDNEY GLOMERULUS and process this filtrate into URINE. Each renal tubule consists of a BOWMAN CAPSULE; PROXIMAL KIDNEY TUBULE; LOOP OF HENLE; DISTAL KIDNEY TUBULE; and KIDNEY COLLECTING DUCT leading to the central cavity of the kidney (KIDNEY PELVIS) that connects to the URETER. Kidney Tubule,Tubule, Kidney,Tubules, Kidney
D009399 Nephrons The functional units of the kidney, consisting of the glomerulus and the attached tubule. Nephron
D011919 Rats, Inbred Strains Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations or by parent x offspring matings carried out with certain restrictions. This also includes animals with a long history of closed colony breeding.

D005246 Feedback A mechanism of communication within a system in that the input signal generates an output response which returns to influence the continued activity or productivity of that system. Feedbacks
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. Animal,Metazoa,Animalia
D013564 Sympathetic Nervous System The thoracolumbar division of the autonomic nervous system. Sympathetic preganglionic fibers originate in neurons of the intermediolateral column of the spinal cord and project to the paravertebral and prevertebral ganglia, which in turn project to target organs. The sympathetic nervous system mediates the body's response to stressful situations, i.e., the fight or flight reactions. It often acts reciprocally to the parasympathetic system.
