Next to rumen acidosis, other forms of acidosis may also affect lactational performance cows. Therefore, the effects hindgut induced via abomasal infusion ground corn, and metabolic NH4Cl, were studied in cows early lactation. Observations made on intake digestibility nutrients, lactation performance, energy N partitioning, blood acid-base status, fermentation characteristics. In a 6 × Latin sq...

To learn whether salt taste responses change during mammalian development, we recorded from multifiber preparations of the chorda tympani while stimulating the anterior tongue in sheep fetuses, lambs, and adults. Stimuli were 0.5 M NH4Cl, KCl, NaCl, and LiCl, and 0.05-0.75 M concentration series of the first three salts. Ultrastructural studies were made of taste buds at different ages to deter...

The main objective of this study was to investigate from the physiological point view, influence that nitrogen and carbon sources have on biomass production activity antimicrobial protein Pseudoalteromonas sp. impact change in medium initial C/N-ratio against S. aureus MRSA evaluated using two different (glucose or citrate) a fixed concentration NH4Cl as source. total organic inorganic (NH4Cl y...

2014 Intrinsic defects tend to oscillate relative to the domains in the two-phase region of the orientational transformation. When the solid is treated as a continuous elastic medium, the vibrational frequencies of vacancies and mobile dislocations are found to decrease as (To T)1/3 and | T0 T |1/2, respectively, near the transition point To. From the ultrasonic excitation of the soft mode of d...

A densimeter technique was used to make a kinetic analysis of the rate of swelling of human erythrocytes suspended in 1% NaCl following successive additions of NH(4)Cl. Two series of experiments were performed, one in the absence of and the other in the presence of 6 x 10(-4)M NaHCO(3). An analysis of the data using Widdas's equations gave a family of curves in each instance. When LeFevre's equ...

The effects on lysosomal movements produced by the weak base ammonium chloride and by a representative polyanion poly-D-glutamic acid (PGA), previously reported to inhibit phagosome-lysosome (P-L) fusion, have been studied in cultured mouse macrophages using direct visual phase-contrast microscopy, a previously described (1, 3, 7) fluorescence assay of fusion, and computer analysis techniques. ...

Aspects of pH regulation in ferret ventricular cells have been investigated by using pH- and sodium-selective microelectrodes in bicarbonate-free Tyrode's solution. An acid load was produced by the transient application of NH4Cl (10 or 20 mmol/l). A complete recovery from an acid load was still observed after multiple applications of NH4Cl, but amiloride (0.75 or 1 mmol/l), a blocker of the Na-...
