Gavage of 2 M NaCl (IG 2 M NaCl), a procedure to induce cell-dehydration-and water and 0.15 M NaCl intake in a two-bottle choice test-is also a potential gastric irritant. In this study, we assessed whether mineral intake induced by IG 2 M NaCl is associated with gastric irritation or production of pica in the rat. We first determined the amount of mineral solution (0.15 M NaCl, 0.15 M NaHCO3, ...

Objetivo: estudiar la evolución a largo plazo de la histología hepática, en pacientes con hepatitis crónica por virus C (VHC) con respuesta sostenida (RS) al tratamiento antiviral y compararla con los pacientes no respondedores (NR) al mismo. Métodos: incluimos un total de 176 pacientes con hepatitis crónica por el VHC, 132 con RS y 44 NR. Todos ellos tenían una biopsia hepática basal y se prac...

Phase-partitioning studies of the euryhaline bacterium Halomonas elongata demonstrated that the hydrophobic-hydrophilic nature of the cell surface changed as the bacterium grew in different NaCl concentrations. Mid-log-phase cells grown in a high (3.4 M) NaCl concentration were more hydrophilic than were cells grown in a low (0.05 M) NaCl concentration. Mid-log-phase cells from defined medium c...

To examine if chronic sodium loading on the brain produces sustained increases in blood pressure, water intake, and sodium excretion, hypertonic (0.5 M and 1.5 M) and isotonic (0.15 M) NaCl solutions were infused into the third ventricle of Sprague-Dawley rats at a rate of 5.5 microliters/hr for 7 days. Intracerebroventricular infusion of 1.5 M NaCl significantly increased systolic blood pressu...

Sour and salt taste interactions are not well understood in the peripheral gustatory system. Therefore, we investigated the interaction of acetic acid and NaCl on taste processing by rat chorda tympani neurons. We recorded multi-unit responses from the severed chorda tympani nerve (CT) and single-cell responses from intact narrowly tuned and broadly tuned salt-sensitive neurons in the geniculat...

the aim of this study was to examine the effects of salinity and light intensity on the chlorophylls, ?-carotene and protein contents in dunaliella salina teod. the algae were grown in inorganic medium containing 0, 0.9, 1.8 (control), 2.6 and 3.5 m nacl under three illumination regimens [4500 (control), 9000 and 11000 lux]. the results showed that most electrophoresis protein bands were separa...

The present study investigated the effects of increased dietary sodium on the modification of cardiac baroreflex responses induced by acute sodium loading. Changes in blood pressure and heart rate during intravenous phenylephrine and nitroprusside administration were compared using a four-parameter sigmoid logistic function before and after a 30-min infusion of 0.6 or 1.0 M NaCl in conscious ma...

The objectives of this study were to determine the extent to which pH and ionic strength influence mu- and m-calpain activity and the inhibition of calpains by calpastatin. Calpastatin, mu-calpain, and m-calpain were purified from at-death porcine semimembranosus. Mu-calpain or m-calpain (0.45 U) were incubated with the calpain substrate Suc-Leu-Leu-Val-Tyr-7-amino-4-methyl coumarin in the pres...
