Carboxylic cation exchange resin effects in dogs.
Reports describing trials of exchange resins in removing cations from the gastrointestinal tract of experimental animals have been limited to toxicity studies and to measurements of the relative magnitudes of the oral intake and the stool output (1-3). In the experiments presented in this paper changes in serum, urine, and stool components, as well as the external and internal balances of certa...
متن کاملBiocompatibility research of a novel pH sensitive ion exchange resin microsphere
The main objective of this study was to investigate biocompatibility and provide in vivo pharmacological and toxicological evidence for further investigation of the possibility of pH sensitive ion exchange resin microsphere for clinical utilizations. Acute toxicity study and general pharmacological studies were conducted on the pH sensitive ion exchange resin microsphere we prepared. The genera...

متن کاملUse of potassium-form cation-exchange resin as a conductimetric enhancer in ion-exclusion chromatography of aliphatic carboxylic acids.
In this study, a cation-exchange resin (CEX) of the K(+)-form, i.e., an enhancer resin, is used as a postcolumn conductimetric enhancer in the ion-exclusion chromatography of aliphatic carboxylic acids. The enhancer resin is filled in the switching valve of an ion chromatograph; this valve is usually used as a suppressor valve in ion-exchange chromatography. An aliphatic carboxylic acid (e.g., ...

NH20H + DPN2H -* NH40H + DPN. If NH4OH is used as substrate and the pH maintained above neutrality, the reverse reaction can be demonstrated (figure 1). In the absence of substrate, extract, or coenzyme no decrease in transmission was noted. NH4C1 and (NH4)2S04 were inactive as substrates at pH 7.0. The enzyme is stable at 60 C for 5 minutes, but not at 65 C. No loss of activity was noted after...
