Electrical properties of the rabbit cortical collecting duct from obstructed kidneys after unilateral ureteral obstruction. Effects of renal decapsulation.
Ureteral obstruction causes impaired salt wastage and K+ secretion in the distal nephron segments, including the cortical collecting duct (CCD). Recently, we demonstrated that conductances of Na+ and K+ in the apical membrane, as well as the electrogenic Na(+)-K+ pump activity and the relative K+ conductance in the basolateral membrane of the collecting duct cell, were inhibited in the obstruct...
متن کاملShort-term effects of uninephrectomy on electrical properties of the cortical collecting duct from rabbit remnant kidneys.
Microelectrode techniques were used to assess the electrical properties of the collecting duct cell in the isolated perfused cortical collecting duct from remnant kidneys 3, 6, and 24 h after uninephrectomy (UNX); results were compared with those from sham-operated kidneys. Plasma aldosterone levels did not change during the time course after UNX. The lumen-negative transepithelial voltage was ...

Compensatory renal growth after unilateral ureteral obstruction. The accumulation of bulk renal protein, RNA and DNA was studied in mice during a 35-day period of accelerated renal growth in the kidney contralateral to that obstructed by acute ureteral ligation. Control mice were sham-operated and nonoperated. RNA was determined by the method of Monroe and Fleck, DNA after Ceriotti and protein ...
متن کاملSimplified Stereological Evaluation of Renal Morphology after Unilateral Ureteral Obstruction
OBJECTIVE AND METHODS This study established a simple stereological method to obtain quantitative information about two- or three-dimensional structures based on observations from kidney sections in the unilateral ureteral obstruction(UUO) model. RESULTS Tubulointerstitial area(TA) and TA/the area of a rectangular field(RA) were raised gradually, but significantly, in the obstructed kidney fr...
متن کاملRenal hydrogen ion secretion after release of unilateral ureteral obstruction.
The effect of 24 h of unilateral ureteral obstruction on HCO3 reabsroption and urinary acidification was studied in dogs. The postobstructed kidney (EK) had a significantly lower glomerular filtration rate and renal plasma flow than the contralateral kidney (CK). Urinary pH prior to HCO3 loading was significantly higher in the EK as was maximal HCO3 reabsorption. Saline loading depressed HCO3 r...
