    摘要: In the production of tablets which are to undergo disintegration in use wherein the tablet components are mixed and pressed into predetermined shape, the improvement which comprises incorporating into the mix at least one inert readily volatilizable solid adjuvant, pressing the mix into shape, and thereafter volatilizing the adjuvant, whereby the resulting tablets are porous, strong, shape retaining and readily disintegratable. Volatilization can be effected by sublimation or application of vacuum. The adjuvant preferably comprises urethane, urea, ammonium carbonate, ammonium bicarbonate, hexamethylene-tetramine, benzoic acid, phthalic anhydride, naphthalene or camphor present in about 5 to 50 percent, especially about 10 to 30 percent, by weight of the total tablet mix.

    摘要: Uric acid is determined by contacting a sample suspected of containing uric acid with a phosphate buffer, an NADH solution, ethanol, alcohol dehydrogenase and catalase in the presence of air to form a reaction mixture containing 0.3 to 0.7 volume percent alcohol, measuring a first extinction value, adding uricase to the reaction mixture, measuring a second extinction value spectrophotometrically and taking the difference between the extinction values as a measure of the initial uric acid content in the sample.

    摘要: 1. IN THE PROCESS OF COATING TABLET CORES OR THE LIKE WITH A COATING COMPRISING PLACING SAID CORES IN A CONTAINER, ROTATING SAID CONTAINER TO MOVE SAID CORES ABOUT, SUPPLYING A SUSPENSION OR SOLUTION OF COATING MATERIAL TO SAID CONTAINER TO COAT SAID CORES AND SUPPLYING A DYRING GAS TO SAID CONTAINER TO DRY THE COATING ON SAID CORES, THE IMPROVEMENT WHICH COMPRISES INTRODUCING SAID DRYING GAS INTO THE BODY OF MOVING TABLET CORES BELOW THE LEVEL THEREOF IN SUCH MANNER THAT A SUBSTANTIALLY TABLET-FREE GAS SPACE IS FORMED JUST BEYOND THE POINT OF DISCHARGE OF SAID GAS, SAID GAS BEING DIRECTED IN THE MAIN DIRECTION OF MOVEMENT OF THE TABLET CORES, SPRAYING OF SAID COATING MATERIAL INTO SAID GAS SPACE TAKING PLACE IN A DIRECTION SUBSTANTIALLY PARALLEL TO THE DIRECTION OF DISCHARGE OF SAID GAS.
