Drug and therapeutics bulletin, 1966
In the article on ethacrynic acid (Edecrin - MSD)1 we said that this drug was the first and so far the only diuretic which has been shown to act on the ascending limb of the loop of Henle. Hoechst have now drawn our attention to work showing that their drug frusemide (Lasix) also acts at this site.2 3

Sodium Reabsorption by the Henle Loop in Humans
Nephron, 2008In a previous study, we described a new method [3] to measure Na reabsorption by each segment of the human nephron independently. Reabsorption was expressed as equivalent volumes of solute-free water (CH<sub>2</sub>O) generated by the loop of Henle (CH<sub>2</sub>O-HL) and by the distal tubule (CH<sub>2</sub>O-DT ...

The Physiology of the Loop of Henle
2009This chapter reports the morphology and function of the thick ascending limb (TAL) of the loop of Henle a crucial segment for many tasks of the nephron. Indeed, the TAL is a mainstay not only for the direct reabsorption of sodium, potassium, and divalent cations but also for its indirect role in the urine renal water reabsorption, overall acid-base ...

Flow correlation of loop of Henle potassium influx
Canadian Journal of Physiology and Pharmacology, 1978Potassium influx in short loops of Henle was assessed using end proximal to early distal perfusion with potassium-free saline. Over a wide range of perfusion rates influx was highly correlated with collected flow rates. The magnitude of the influx was comparable with the delivery rate of potassium to the early distal site seen during free flow, over a

Function of the thick ascending limb of Henle's loop
American Journal of Physiology-Legacy Content, 1973BURG, MAURICE, AND NORDICA GREEN. Function of the thick ascending limb of Henle’s loop. Am. J. Physiol. 224(3) : 659-668. 1973.-The thick ascending limb of Henle’s loop was dissected from rabbit kidneys and perfused in vitro. There was net NaCl absorption from the tubule lumen with resultant lowering of lumen NaCl concentration below that of the bath ...

Volume reabsorption by the Loop of Henle: A micropuncture study
Experientia, 1980The observed extension of glomerulo-tubular beyond the proximal tube is thought to be due either to flow dependent reabsorption by non-accessible proximal segments and pars recta, or to osmotic volume flow out of the descending limb of the loop of Henle.

Evidence of calcium phosphate supersaturation in the loop of Henle
American Journal of Physiology-Renal Physiology, 1996We have used published rat micropuncture data to construct a matrix of ion concentrations along the rat nephron. With an iterative computer model of known ion interactions, we calculated relative supersaturation ratios in all nephron segments. The collecting ducts and urine showed expected supersaturation with stone-forming salts.

Transport Characteristics of the Loop of Henle
1978The loop of Henle was early identified as a structure essential for the concentration of the urine, since it occurs only in birds and mammals, the two classes that produce urine with osmolality higher than the blood. Subsequent study of the loop of Henle has mainly involved its role in urinary concentrating mechanisms.

Tubuloglomerular Feedback Signal Transduction in a Short Loop of Henle
Bulletin of Mathematical Biology, 2009In previous studies, we used a mathematical model of the thick ascending limb (TAL) to investigate nonlinearities in the tubuloglomerular feedback (TGF) loop. That model does not represent other segments of the nephron, the water, and NaCl transport along which may impact fluid flow rate and NaCl transport along the TAL.

Claudin Function in the Thick Ascending Limb of Henle's Loop
Annals of the New York Academy of Sciences, 2009During the past decade, claudins have been established as major determinants of paracellular permeablilty in epithelia. In the kidney, each nephron segment expresses a distinct pattern of claudins. Cells of the thick ascending limb of Henle's loop (TAL), which is characterized by high paracellular cation permeability, co‐express an unusually large ...
