Age-related changes in Na+ excretion in saline-loaded spontaneously hypertensive rats
American Journal of Physiology-Legacy Content, 1976The ability of 6- to 7-, 12- to 13-, and 16- to 17-wk-old spontaneously hypertensive rats (SHR) to excrete an acutely administered, isotonic saline load (equivalent to 4.5% body wt) was evaluated. Female SHR from two different colonies were studied. Age-matched female Wistar (W) and Wistar-Kyoto (WKY) rats served as controls. At age 6 wk, the fraction

The effect of acute saline volume expansion on renal Na?K-ATPase
Pfl�gers Archiv European Journal of Physiology, 1985To examine the role of Na-K-ATPase in the natriuresis that occurs after acute extracellular volume expansion, we performed acute clearance experiments and in vitro analysis of renal microsomal ATPase activity in rats receiving intravenous 0.9% sodium chloride (0.1 ml/100 g bw/min). Despite increased absolute reabsorption of filtered sodium (196 +/- 8.1

Characterization of Na+ exclusion mechanism in rice under saline-alkaline stress conditions
Plant Science, 2019This study was designed to elucidate the physiological responses of two rice genotypes to different pH levels under high saline stress. A salt-tolerant cultivar, FL478, and a salt-sensitive cultivar, IR29, were exposed to saline-alkaline solutions supplemented with 50 mM Na at pH 9 (severe), pH 8 (moderate), and pH 7 (mild) for three weeks. The results

Contribution of two different Na+ transport systems to acquired salinity tolerance in rice
Plant Science, 2020To elucidate the mechanisms of salt acclimation, physiological parameters of 70 rice varieties were compared under control and salt stress conditions after the acclimation treatment. The results indicated that some rice varieties had the ability to acclimatize to salt stress, exhibiting improved growth following the acclimation treatment under ...

The K/Na and Ca/Na ratios and rapeseed yield, under soil salinity or sodicity
Plant and Soil, 1995Rapeseed (Brassica napus) is a crop relatively tolerant to salt and sodium. Our objective was to study the interactions between Na, K and Ca and their relationship with its yield under the isolated effects of soil salinity or sodicity.

Groundwater salinization processes: pitfalls of inferences from Na+/Cl− versus Cl− correlation plots
Environmental Geochemistry and Health, 2020Despite some researches indicating the possibility of correlation being induced by the common variable effect, correlation plots of ionic ratio (Na+/Cl-) versus ionic concentration (Cl-) still remain popular for interpreting the causes of groundwater salinization.

Renal Na‐K‐ATPase Activity during Saline Infusion in the Rabbit
Acta Physiologica Scandinavica, 1977AbstractDuring saline infusion, sodium reabsorption (RNa) in the diluting segment (thick ascending limb of Henle's loop) increases acutely. The mechanism for this higher pumping rate of outer medullary Na‐K‐ATPase is unknown. Following left‐sided nephrectomy, immediate i.v.
