Abstract: A method for decreasing urinary calcium content which comprises orally administering to a person whose urine contains insoluble calcium containing precipitates or has a propensity for forming calcium containing precipitates, an effective amount of an agent selected from water-soluble vinylbenzenesulfonic acid polymers and the nontoxic pharmaceutically acceptable salts thereof.

Abstract: The calcium salts of the solid cyclic copolymers of divinyl ether and maleic anhydride, soluble in water, have been found to be as effective in treating tumors and viruses as the prior art alkali metal salts (e.g., the sodium salt) but much less toxic. These copolymers are characterized by containing divinyl ether and maleic anhydride in a mole ratio of about 1:2, having a molecular weight of from about 2000 to about 100,000 and from about 5% to about 70% of its carboxylic acid groups converted to calcium salts.

Abstract: A quantitative evaluation of the intestinal microflora is made by administering to an animal organism an effective amount of novel chemical conjugates of a bile acid or related acid with an amino acid which will be cleaved from the bile or related acid by the enzymes elaborated by the intestinal microflora and then measuring the amount of the released amino acid in the urine after a predetermined time interval. The novel compounds and their use in in vitro tests are included in the invention.

Abstract: Water soluble and colloidially water soluble polymers of carboxylic acid-containing monomers useful for treating kidney stones are disclosed.
