Acute hyperkalemia has been associated with changes in reabsorption, glomerular filtration rate (GFR), and autoregulation, which might represent altered tubuloglomerular feedback (TGF) responsiveness. Therefore, TGF responsiveness, segmental reabsorption of water, sodium and potassium, and single-nephron GFR were evaluated during acute potassium loading in male Sprague-Dawley rats. Rats receiving 300 mM KNO3, KHCO3, and KCl showed significantly increased plasma potassium levels and attenuation…

Renal potassium handling in rats with subtotal nephrectomy: modeling and analysis.
TLDR
Model simulations suggest that the lesser natriuretic effect observed in the nephrectomized groups may be explained by impaired NCC downregulation in these kidneys.
Acute saline expansion increases nephron filtration and distal flow rate but maintains tubuloglomerular feedback responsiveness: role of adenosine A(1) receptors.
TLDR
Closed-loop assessment of TGF in hydropenia and after acute saline volume expansion demonstrated TGF adaptation, which facilitates fluid and Na(+) excretion and stabilizes early distal delivery at the new setpoint in an A(1)R-dependent mechanism.
NaHCO(3) and KHCO(3) ingestion rapidly increases renal electrolyte excretion in humans.
TLDR
The kidneys were important in mediating rapid corrections of substantial portions of the fluid and electrolyte disturbances resulting from ingestion of KHCO(3) and NaHCO( 3) solutions.
Proteinuria, lipoproteins and renal apolipoprotein deposits in uninephrectomized female analbuminemic rats.
TLDR
The development of proteinuria and glomerulosclerosis after UNX in female NAR but not in male NAR may depend upon differences in plasma lipoprotein composition, but is apparently not related to differences in whole kidney hyperfiltration and hyperperfusion, glomerular capillary pressure, or blood viscosity.

Blood sampling from the retro-orbital plexus, the saphenous vein and the tail vein in rats: comparative effects on selected behavioural and blood variables
TLDR
It was found that induction of diethyl-ether anaesthesia combined with orbital puncture caused more distress than did the other two blood sampling techniques and some haematological and plasma variables differed significantly between the three blood collection techniques.
