Abstract: 547,518. Blood preparations. ABBEY, A. (Witebsky, E., and Klendshoj, N. C.). Nov. 19, 1940, No. 16680. [Class 81 (i)] Blood for transfusion of the type known as 0 is conditioned so as to render it suitable for administration to patients of other types by inhibiting the effects of the isoagglutinins A and B, which occur therein and cause agglutination respectively of the A factor and B factor, by reacting the blood with specific substances denoted as A and B specific substances which render these isoagglutinins substantially ineffective. A type blood also is conditioned by inhibiting the B isoagglutinins therein by reacting it with B specific substance. The A specific substance is obtainable from tissues and excretions of animals and humans of A type, and B specific substance from those belonging to B type, their presence being ascertained by adding A cells to a serum known to contain the A isoagglutinin when absence of agglutination indicates the presence of the A specific substance and mutatis mutandis in the case of B specific substance. The specific substances are obtained by precipitation from aqueous solution by alcohol in presence of an electrolyte e.g. sodium acetate, redissolution and precipitation and deproteinization of the clear solution e.g. by shaking with chloroform in presence of butyl or amyl alcohol. The clear supernatant liquid is dialysed to remove smaller molecules and the solution treated with acetone to precipitate the active substance. Examples describe the preparation of A specific substance from peptone and of B specific substance from gastric juice. Methods of standardization of the active substances and details of their utilization in the preparation of transfusion blood are described in the Specification.

IPC: A61K6/90
Filed: 1963-04-29
Abstract: A preparation for taking dental impressions and to be prepared for use by mixing it with water, comprises a colloid, a metal salt, and alkaline component which when the preparation is mixed with water renders the preparation alkaline so that the metal salt is initially substantially insoluble in the water and incapable of reacting with the colloid, and a slow acting acidifying component which causes the alkaline preparation to assume a neutral or slightly acid pH value so that the metal salt dissolves in the water and reacts with the colloid to form a resilient gel, the acidifying component being in stoichiometric excess with respect to the alkaline component.  The metal salt may be a carbonate or silicate of lead, barium, strontium or calcium.  The colloid may be a water soluble alginate, pectate or salt of carboxymethyl-cellulose.  The acidifying component may be a weak acid (acetic acid), a salt derived from a weak base and a strong acid, an organic or inorganic ester, an organic or inorganic acid anhydride (molybdic or tungstic acid anhydride), a silicofluoride, a titanofluoride or a zirconofluoride.  The alkaline component may be sodium hydroxide or alkali metal silicate, aluminate or zincate.  The preparation may include colour change indicators e.g. phenolphthalein and thymolphthalein.
