EFFECT OF MERTHIOLATE (LILLY) ON CERTAIN SPECIFIC PRECIPITATION REACTIONS.
Merthiolate (Lilly), a substituted benzoic acid, has been shown to interfere, in concentrations usually used for preservation, with the specific precipitation of antisera against beef serum or sheep serum coupled with diazotized p-aminobenzoic acid, p-arsanilic acid, or p-(p-aminophenylazo) phenylarsonic acid. In some systems increased precipitation was observed, while in others decreased precipitation was observed.
SYNTHESIS OF RADIOACTIVE SUCROSE BY TOBACCO LEAVES FROM C14 UNIFORMLY LABELLED GLUCOSE AND GLUCOSE-1-PHOSPHATE
Detached tobacco leaves were placed for six hours on solutions of C14 labelled glucose and glucose-1-phosphate. At the end of this time leaves were extracted with boiling 80% ethanol and the activi...
Effects of diet on urine composition of cats with calcium oxalate urolithiasis.
Ten client-owned cats with calcium oxalate (CaOx) urolithiasis were evaluated to determine the effect of diet on urine CaOx saturation. Two dietary treatments were evaluated in each cat: the diet consumed just prior to urolith detection and a canned diet formulated to prevent CaOx uroliths. This study revealed that hypercalciuria is a consistent abnormality in cats with CaOx urolith formation. When urolith-forming cats consumed a diet formulated to prevent urolith formation, activity product ratios for CaOx (which estimate the degree to which urine is saturated with CaOx) were significantly lower. These results suggest that consumption of an appropriately formulated urolith-prevention diet will reduce recurrence of CaOx urolithiasis.
