Abstract: The combination of two tests, a procoagulant assay (PA) and a heparin-procoagulant assay (H-PA) makes it possible to determine the status of a patient with respect to thrombosis and whether a prethrombotic condition exists. The results of the tests can be used to determine whether and what type of treatment is necessary.

Abstract: Fish eggs which have been rendered hard and substantially opaque by coagulation of their protein content are made into fish egg bait by treating them with an aqueous acid solution of urea, i.e. with an acid salt of urea, and under conditions predetermined to swell and plasticize the eggs and render them substantially translucent.

Abstract: An improvement in process for producing encapsulated condiment particles by spray drying wherein a special surface-coating step is done while subjecting such particles to spray drying.

Abstract: Substrate for determining proteinases wherein a substrate protein is bound by a covalent bond in fine distribution in or on the surface of a solid carrier and dyed with a reactive dyestuff, its manufacture and its use.

Abstract: New application of an aqueous alkali solution of cyclohexylaminopropanesulfonic acid, said acid being contained therein with a specific range of concentration and said solution having a specific range of pH value, as a stopping agent for stopping an enzyme reaction of a dehydrogenase or a dehydrogenase system in a spectrophotometric assay method of an activity of serum enzyme in said enzyme or enzyme system.

Abstract: The method of orally feeding animals including humans Lactobacillus lactis NRRL B-5628 to restrict the growth of other digestive system (such as mouth, crop and/or stomach) bacteria is described. NRRL B-5628 is particularly useful in the treatment of scouring, diarrhea or colibacillosis in baby pigs and other newborn animals by reducing the intestinal population of E. coli as the native coliform bacterium. The oral feeding of NRRL B-5628 is also used in farrowing sows to reduce intestinal bacteria and in turn to reduce such bacterial populations in the newborn pigs. Mastitis-metrites syndrome in gilts, sows and cows is reduced by such oral feeding.

Abstract: A method of culturing monogastric animals which comprises feeding the animals a feed in which part of the protein is supplied by a urea-isobutyraldehyde condensate.

Abstract: Aeromonas sp. No. 212 is cultured to allow it to produce a novel cellulase 212 and/or novel hemicellulase in a culture medium, and the so produced cellulase 212 and/or hemicellulase 333 is separated from the culture medium.The so separated novel cellulase 212 and/or novel hemicellulase 333 is used as a cellulosic material-decomposing agent in purifying tanks, plants for treatment of industrial waste waters, excrement treatment plants, drainage disposal treatment plants and the like.

Abstract: A hyaluronic acid-enriched mycobacteria culture medium whose base is either Dubos oleic acid-albumin liquid medium or a physiological mixture of fresh yeast extract in a phosphate buffer of pH 5.5 to 7 optionally containing bovine serum albumin, glycerine, a contaminating organism-growth inhibitory antibiotic, and a gelatinizing agent to solidify the culture medium for plate use. The culture medium has particular utility for the in vitro cultivation of leprosy mycobacteria, which exhibit prolific growth when inoculated and maintained in such culture medium at temperatures within the range of about 25.degree.C to about 37.5.degree.C.

Abstract: A method of determining minimum inhibitory concentration (MIC) of an antibiotic by continuously measuring the change in optical properties in response to the bacterial growth rate of a bacterial suspension in the absence and the presence of the antibiotic. The method is carried out in an automatic biological fluid analyzer.

Abstract: A process for the production of microbial cells by fermenting a carbonaceous material in a foam fermenter containing an oxygen-enriched nutrient medium. The process uses a source of carbon which is assimilable by the microorganism for the production of the microbial cells. The microbial cells are separated and removed from the foam fermenter for use as a food product high in protein content.

Abstract: A technique and apparatus used therewith for determining the uptake of plutonium and other contaminants by soil microorganisms which, in turn, gives a measure of the plutonium and/or other contaminants available to the biosphere at that particular time. A measured quantity of uncontaminated spores of a selected mold is added to a moistened sample of the soil to be tested. The mixture is allowed to sit a predetermined number of days under specified temperature conditions. An agar layer is then applied to the top of the sample. After three or more days, when spores of the mold growing in the sample have formed, the spores are collected by a miniature vacuum collection apparatus operated under preselected vacuum conditions, which collect only the spores with essentially no contamination by mycelial fragments or culture medium. After collection, the fungal spores are dried and analyzed for the plutonium and/or other contaminants.

Abstract: An integral analytical element for analysis of liquids for their cholesterol content is disclosed. The element is of the type which comprises at least two superposed layers including a spreading layer and a reagent layer in fluid contact and, optionally, a support. Cholesterol oxidase and a composition for the hydrolysis of cholesterol esters comprising lipase having cholesterol esterase activity and protease are included in the element such that cholesterol esters contained in a sample applied to the spreading layer are saponified to free cholesterol and free cholesterol is decomposed in the presence of cholesterol oxidase to produce a detectable change related to the total cholesterol content of the sample.

Abstract: A process for the preparation of galactose which comprises (1) the cultivation of a mutant, non-pathogenic protoprophic yeast or bacteria possessing .beta.-galactosidase activity and a gal.sup.- character on a media containing lactose, e.g., lactoserum and (2) recovery of the galtose. The mutants are produced using two different methods. The galactose solutions produced are suitable for use in beverages.

Abstract: 3-Furyl .beta.-chalcogenalkyl sulfides having the structure: ##SPC1##Wherein X is a chalcogen selected from the group consisting of oxygen and sulfur; R.sub.2 and R.sub.3 are each selected from the group consisting of methyl and hydrogen, at least one of R.sub.2 and R.sub.3 being methyl; and R.sub.4 and R.sub.5, taken separately, are each methyl, or R.sub.4 and R.sub.5 taken together are tetramethylene, and when R.sub.4 and R.sub.5 taken together are tetramethylene X and S are in a trans relationship, are indicated to be useful in altering, modifying or enhancing the taste and/or aroma of foodstuffs.

Abstract: A soy cheese spread having excellent spreadability, oral melting and flavor characteristics is made by admixing a soy cheese, prepared by fermenting soy milk with a lactic acid-forming cheese starter culture to form a curd, with an edible oil or fat, a cheese emulsifying melting salt, and water and then vigorously agitating this mixture at an elevated temperature to liquefy and homogeneously emulsify the ingredients thereof and thereby form a product having a paste-like consistency.
