Abstract: (A) A clad powdery or granular preparation of a medicinally active ingredient and (B) a powdery or granular ion exchanger such as a cation exchange resin are blended to prepare a solid preparation. The active ingredient includes .beta.-lactam antibiotics having a basic group. The clad powdery or granular preparation includes not only coated preparation wherein the active ingredient or preparation is coated but also a variety of preparations in which the contact of the active ingredient with the ion exchanger is suppressed or inhibited. Polymers such as a water-soluble polymer, an enteric polymer and so on can be used as the coating agent for the coated preparation. The using amount of the ion exchanger is about 10 to 5,000 parts by weight per 100 parts by weight of the active ingredient. Said solid preparation can remarkably decrease the unpleasant taste and odor of the active ingredient such as bitterness, being excellent in dissolution property and absorbability of the active ingredient.
Abstract: A bath additive composition comprises an aluminum salt and a carbonate and makes the pH of bath water 8 or higher but less than 9 when the bath additive composition is dissolved in the bath water. The bath additive composition does not damage bathtubs, bath water heating devices, or the skin of users, provides a refreshing feel to the skin after bathing, and has an excellent ability of suppressing perspiration.
Abstract: Alumina hydrate particles have a high surface area and low dispersity and may have a low soluble soda content. They may be made by milling a liquid suspension of alumina hydrate, subjecting the milled suspension to classification into coarse and fine fractions, recycling the coarse fraction to the mill and recycling the fine fraction to the classification stage. A narrow particle size distribution is obtained.
Abstract: An antitumor polymeric composition comprising an anthracene antitumor compound, particularly mitoxantrone, covalently conjugated to, or admixed with, a divinyl ether-maleic anhydride (MVE) copolymer and methods of treating solid tumors and inducing regression of leukemia cell growth in mammals by administering such compositions.
Abstract: A smooth, greaseless skin ointment especially prepared for irritated skin, which protects, adheres and simultaneously is easily washable without causing skin damage. The ointment base is a blend of polyethylene glycols. It is combined with a bioadhesive which works synergistically to allow the blended ointment base to adhere to wet and moist areas, while not being so adhesive as to cause damage when removed in washing. Specifically a blend of polyethylene glycol polymers is prepared to provide good skin feel and drag, a polyvinyl ether anhydride salt bioadhesive is added and a polyvinylpyrrolidone is also used as a dispersant, and feces and urine toxicant binder. Optionally minor amounts of dimethicone can be added.
Abstract: A solid iodine concentrate composition comprising an iodine complex, and a solidifier wherein said iodine complex comprises a complexing agent and an iodine source present in a ratio of at least 1.5:1.
Abstract: This invention relates to an antifungal block copolymer of poly(vinyl lactam) having the formula ##STR1## where m has a value of from 1 to 3 and from about 15 to about 25 wt. % of a quaternized amino alkyl acrylamide comonomer wherein the quaternizing anion is in part halide --O--CO(CH.sub.2).sub.s CH.dbd.CHZ wherein s has a value of from 4 to 14 and Z is hydrogen or a C.sub.1 to C.sub.4 alkyl radical, which copolymer is comprised of the following units ##STR2## wherein m has a value of from 1 to 3; p has a value of from 1 to 5; r has a value of from 2 to 6; each of X and Y is hydrogen or a C.sub.1 to C.sub.4 alkyl and each of R.sub.1, R.sub.2 and R.sub.3 is C.sub.1 to C.sub.4 alkyl. The invention also relates to the use of the above polymers as antifungal agents.

Abstract: Aqueous thiocarbonate solutions are stabilized by the addition of base, sulfide and/or polysulfide, and the stability and safety of the more concentrated solutions containing 1 weight percent or more equivalent CS.sub.2 as a thiocarbonate are achieved as reflected by significant reduction of CS.sub.2 partial pressure in such solutions.
Abstract: A defined serumfree medical solution for applications in Ophthalmology, that contains one or more cell nutrient supplements which maintains and enhances the preservation of eye tissues, including human corneal tissues at low temperatures (2.degree. C. to 15.degree. C.). This solution is composed of a defined aqueous nutrient and electrolyte solution, supplemented with a glycosaminoglycan(s), a deturgescent agent(s), an energy source(s), a buffer system(s), an antioxidant(s), membrane stabilizing components, antibiotic(s), ATP precursors and nutrient cell supplements.
Abstract: A resorbable porous tricalcium phosphate, in which the pores are sealed with a filler mixture of an antibiotic and a filler, in particular an amino acid, is particularly advantageous for use in the preparation of bone cements.

Abstract: Process for preparing anion exchange resins comprising polymerizing a vinyl aromatic compound having at least one alkyl group containing about 1 to 3 carbon atoms, alone or mixed with a copolymerizable monomer, optionally in the presence of a mineral support, followed by brominating the alkyl groups of the resulting polymer by means of an N-bromoamide or an N-bromoimide, and then aminating the brominated product obtained. The resulting anion exchange resins are useful in the chemical, pharamaceutical, food, and metallurgical industries.
Abstract: A process for preparing a cation-exchange resin is disclosed. The process comprises:(a) treating a chlorine-containing material, which is the distillation residue obtained by chlorinating or oxychlorinating a C.sub.2 -C.sub.40 hydrocarbon, with a sulfonating agent,(b) treating the admixture of step (a) with water and an organic solvent until the product shows a substantially neutral pH, and(c) removing the volatile materials to obtain a solid material which is suitable for use as a cation-exchange resin.
Abstract: A basic copolymer whose main chain is cross-linked which comprises about 6 to about 98% by weight of recurring units of Formula (A) or (B), ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3, which may be the same or different, each represents a hydrogen atom or a hydrocarbon group selected from the group consisting of C.sub.1-20 alkyl groups, C.sub.3-10 cycloalkyl groups, C.sub.3-8 alkenyl groups, C.sub.6-15 aryl groups, C.sub.7-12 arylalkyl groups and C.sub.1-15 aminoalkyl groups; and X is an acid radical, and about 2 to about 94% by weight of cross-linked units based on the total weight of the recurring units of Formula (A) or (B) and the cross-linked units and, if desired, up to about 92% by weight of units of a monoethylenically unsaturated monomer or a conjugated monomer based on the total weight of the recurring units of Formula (A) or (B), the cross-linked units and the units of the monoethylenically unsaturated monomer or the conjugated monomer.
