Abstract: Iodo-aryl carbonates, such as for example, p-iodo-benzyl carbonates, p-iodo-sec-phenethyl carbonates, p-iodo-phenethyl carbonates, p-iodo-phenyl carbonates, 3-(p-iodophenyl)propyl carbonates, 3-(p-iodophenyl)butyl carbonates, 2-(p-iodobenzyl)butyl carbonates and 2-(p-iodobenzyl)-n-hexyl carbonates, for use as radiographic media in connection with such techniques as x-ray applications including myelography, salpingography, lymphography and bronchography. An effective quantity of iodinated organic carbonate provides x-ray contrast, and the compounds of the invention may be characterized generally as carbonates having the general formula ##STR1## wherein R represents an alkyl group having from 4 to 10 carbon atoms and R' represents an iodinated phenyl linked to the ester oxygen through an alkyl chain consisting of 1 to 3 carbon atoms.
Abstract: This invention relates to an improved composition for inhibiting dental plaque and calculus formation, comprising zinc ions and a non-toxic, organoleptically acceptable antibacterial agent in an orally acceptable medium, and to a process for retarding the growth of dental plaque and calculus by application to the teeth of the above composition.
Abstract: This invention discloses the compound N-.alpha.-chloroacetyl-N-(1,3-dioxolan-2-ylmethyl)-2-ethyl-6-methylaniline and its utility as a herbicide.
Abstract: Two eosinophilotactic tetrapeptides of amino acid sequence Val-Gly-Ser-Glu and Ala-Gly-Ser-Glu have been isolated from extracts of human lung fragments. These tetrapeptides have been synthesized by solid phase peptide synthesis procedures and the synthetic and natural materials behaved similarly in analytical assays and bioassays. Novel N-terminal analogs have been prepared and have shown eosinophilotactic activity. Thus, the tetrapeptides disclosed herein have utility as therapeutic agents in the prophylaxis and/or treatment of parasitic diseases, anaphylaxis and bronchial asthma.

Abstract: Respiration of sucrose to carbon dioxide and water is reduced and the formation of invert sugar is inhibited in the storage of sugar beets which have had an effective amount of ethylene introduced into the ground near the roots of the growing plants.
Abstract: There is provided, a novel pro-drug form of digoxin having the following formula: ##STR1## wherein R represents a member selected from the group consisting of a hydrogen atom, a residue of any naturally occurring amino acid, and a ##STR2## group, wherein X and Y, which may be the same or different, each represent a member selected from the group consisting of a methyl group and an ethyl group, or wherein X and Y may form a (CH.sub.2).sub.4 or (CH.sub.2).sub.5 heterocyclic ring with the N atom to which each of X and Y are attached, and a non-toxic inorganic or organic pharmaceutically acceptable acid addition salt thereof, with the proviso that:When R is a member other than a hydrogen atom, all of said R's must be the same member.These novel compounds will be cleaved in the bloodstream of a warm-blooded animal, thus delivering digoxin in a cardiotonic effective amount.
Abstract: The masking N-formyl group of an N-formyl-amino acid ester or N-formyl-peptide ester is removed without major side reactions when the ester is reacted in an inert liquid medium with hydroxylamine of which at least 70% is present in the form of a salt with a strong acid, the remainder, if any, being present as the free base or the salt of a weak acid.
Abstract: 2,5-Dimethyl-1-pyrrole-lower-alkanecarboxamides, prepared by reaction of a 3-R.sub.3 -4-R.sub.4 -2,5-hexanedione with either an .omega.-amino-lower-alkanonitrile or an .omega.-amino-lower-alkanecarboxamide, and if appropriate, hydrolysis of the resulting 2,5-dimethyl-3-R.sub.3 -4-R.sub.4 -1-pyrrole-lower-alkano-nitrile, have anti-secretory and anti-ulcer activities.
Abstract: Compounds of the formula ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are hydrogen or carboxylic acyl, particularly acetyl, benzoyl or p-nitro-benzoyl; the compounds are useful as cardiotonics.

Abstract: The derivatives of digoxin useful in the radioimmunoassay of digoxin having the following formulae: ##STR1## where R is a carboxylic acid ester. These derivatives are formed by the following process: (1) reacting the carboxylic acid in the presence of trifluoroacetic anhydride with a solution of digoxin in an inert, nonaqueous solvent medium, (2) adding water so as to form the above derivatives, (3) purifying the above derivatives from other constituents of the reaction mixture and (4) radio-labeling these derivatives for use as a labeled hapten in the radioimmunoassay of digoxin.The preferred carboxylic acids are imidazoleacetic acid and p-hydroxyphenylpropionic acid. The preferred radioactive isotope is .sup.125 I.

Abstract: Glucose polymers having an average chain length of 3 - 8 units are added to an electrolyte solution which normally has a saline taste in an amount to substantially disguise the saline taste of the electrolyte solution. Preferably, the polymer is added in an amount in the range of 15% to 50% by weight and the electrolyte solution contains the usual chloride salts of calcium, magnesium and potassium with the solution having a pH in the range of 3 - 6.
Abstract: A method for producing a novel immunizing agent is described. The immunizing agent is anti-HB.sub.s gamma globulin essentially free of fibrinogen, plasminogen, 19 S globulin and lipids found to be effective in immunizing against hepatitis B virus disease. The method of producing this material involves fractionation of human plasma utilizing selective solvent and control of pH, temperature and ionic strength.
