1. Respiration and fermentation of yeast receiving 90,000 r of 250 kv. x-rays were studied under a variety of conditions. This dose will nearly completely inhibit growth or colony formation. 2. The apparent effects of irradiation are quite dependent on the K(+) and H(+) of the suspending medium. At pH 4.5 stimulatory effects were observed in KH(2)PO(2) buffer and inhibition in potassium-free (T...
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...
The aim of this study was to remove Cd by ion-exchange resin Amberjet 1200H in flow condition. The adsorption characteristics of metal onto the resin were accurately described by Freundlich isotherms. The ion exchange of cadmium on resin follows pseudo-second-order kinetics. Ion exchange capacities of the cadmium on the ion exchange resin was studied in metal solution. The capacities of sorptio...
Experiments were conducted to determine the effect of bentonite and nonnutritive dietary polymers on toxicity and metabolism of T-2 toxin in rats. Male weanling rats were fed diets containing 5% bentonite, anion exchange resin, cation exchange resin or vermiculite-hydrobiotite. Each diet was fed with and without 3 micrograms T-2 toxin/g of feed for 2 wk. Bentonite and anion exchange resin were ...
