Renal Micropuncture Techniques: A Symposium *
Micropuncture, microperfusion, and microelectrode techniques applied to the study of single tubules are among the most powerful methods available for investigating problems of renal function. Studies of single nephrons have yielded considerable insiglht into many aspects of glomerular and tubular function. For example, the magnitude and the site of many tubular reabsorptive and secretory proces...
متن کاملElectrophysiological techniques in kidney micropuncture.
Electrophysiological techiniques lhave been wiclely uised for the investigation of membrane properties in excitable andl inexcitable tissues. The application of suclh metlho(ds to epitlhelia lhas been extensive, particuilarly for structures that can be mounte(d as an isolated tisstue slheet in special chambers designed to control the bathing soltutions. Witlh respect to the sttu(ly of the renal...
متن کاملAttempts to demonstrate a hormonal nattriuretic factor by micropuncture techniques.
It is clear that acute expansion of the extracellular fluid volume produces an increased excretion of sodium by the kidneys, due at least in part to reduced absorption in the proximal tubule. When saline is infused rapidly, fractional reabsorption of the glomerular filtrate is reduced in the proximal tubules of dogs and rats.'2 Under the same circumstances a reduction of the reabsorptive capaci...
متن کاملThe antimony microelectrode in kidney micropuncture.
The use of pH-sensitive microelectrodes for the determination of ttubular pH in amplhibian neplirons dates from the early days of kidney micropuncture. Soon after this metlhodology was introduced by Riclhards and hiis coworkers, MIontgomery and Pierce(1,2) publislhed their papers on the (letermination of tubular pH in Necturus and in frogs by means of a quinlhydrone microelectrode. In this micr...
متن کاملMicropuncture: unlocking the secrets of renal function.
This essay looks at the historical significance of five APS classic papers that are freely available online: Wearn JT and Richards AN. Observations on the composition of glomerular urine, with particular reference to the problem of reabsorption in the renal tubules. Am J Physiol 71: 209-227, 1924 (http://ajplegacy.physiology.org/cgi/reprint/71/1/209). Richards AN and Walker AM. Methods of colle...
