The kinetics of the induction of rat kidney phosphoenolpyruvate carboxykinase activity after triamcinolone and ammonium chloride administration have been investigated with a view to the further differentiation of the two processes. The half-life of kidney phosphoenolpyruvate carboxykinase activity, as measured from the decay curve after a single doses of triamcinolone, is approximately 1.4 hr. ...

Cardiac myosin prepared by any one of a number of modifications of the basic Szent-Gyorgyi method and cardiac myosin prepared by the lithium chloride-ammonium sulfate technique differ in two important respects: 1) SzentGyorgyi-prepared myosin solutions are inhomogeneous by both chemical and immunologic criteria; 2) the ATPase activity of Szent-Gyorgyi-prepared myosin is low in comparison to lit...

Ammonium chloride was added to diets varying in Ca content to evaluate its potential in preventing silica urolith formation in sheep. A 2 x 2 factorial experiment involved wether lambs with ad libitum access to a diet of 50% grass hay and 50% ground oats plus supplement. The basal diet contained on a DM basis 3.3% SiO2, .31% Ca, .22% P, 11.6% CP, and 26% ADF. Treatments (38 to 39 lambs/treatmen...

The inhibitory effect of ammonium choride pretreatment of human peripheral blood lymphocytes on natural killer (NK) activity to myeloid leukemic cell line K-562 was studied. The more dilute the ammonium chloride solution, the less was the inhibitory effect on NK activity. This inhibitory effect was weaker when effector cells were treated at 4° C than at 37° C. Inhibited NK activity recovered pa...

Four constitutional isomers of BMpillar[5]arene were prepared from 1-butoxy-4-methoxybenzene and they showed different binding abilities with n-octyltrimethyl ammonium hexafluorophosphate.

The title compound, ammonium potassium iron(III) phosphate fluoride, (NH(4))(0.875)K(0.125)FePO(4)F, is built from zigzag chains (∞) (1){[FeO(4)F(2)](7-)}, with Fe(3+) in a distorted octahedral coordination, extending along both the [011] and [01] directions. These chains are made up of alternating trans-[FeO(4)F(2)] and cis-[FeO(4)F(2)] octa-hedra via shared F-atom corners, and are linked by P...

We describe a patient who had consumed large quantities of a proprietary cough mixture containing diphenhydramine, ammonium chloride and sodium citrate (Benylin expectorant) daily for several months and subsequently presented with confusion, marked metabolic acidosis and non-ketotic hyperglycaemia.

A one-pot three component condensation synthesis of imidazo[1,5-a]pyridines using of various aromatic aldehydes and dipyridil ketone with ammonium acetate in the presence of Lithium chloride as catalyst in good yields under microwave irradiation has been described.

The calcium/calmodulin-regulated Ca-ATPase of the plasma membrane is implicated in Paramecium chemosensory transduction. Calmodulin antisense oligonucleotides electroporated into Paramecium disrupt chemosensory responses to sodium acetate but not to ammonium chloride.
