A method for lowering serum total cholesterol in an animal by administering to the aminal an anion-exchange resin having the monomer units respectively represented by the below-given structural formulas (I), (II), (III) and (IV) in a content of 60-95 molar % of the monomer unit (I), 0-25 molar % of the monomer unit (II), 0--30 molar % of the monomer unit (III) and 1-6 molar % of themonomer unit (IV). ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 which may be the same or different respectively are hydrogen atom, a lower alkyl group or benzyl group, R.sup.4 is hydrogen atom, a lower alkyl group or hydroxy-methyl group and X is a halogen atom. The above-mentioned agents specifically bind with bile acid in the intestinal tract even in the presence of other acids.

Cholesterol-lowering agents

A hydrophilic separating carrier is a porous spherical gel having primary hydroxyl groups and is produced by an aqueous suspension homopolymerization of pentaerythritol dimethacrylate or an aqueous suspension copolymerization of pentaerythritol dimethacrylate and a methacrylate monomer having hydrophilic group and/or hydrophilic convertible group.

Hydrophilic separating carrier and preparation thereof

2-Nitrocycloalkanone, and its derivatives are prepared by reacting in a single step a cycloalkene with nitrogen dioxide and an oxygen containing gas in the presence of an aromatic hydrocarbon solvent having 6 - 10 carbon atoms, and a dimethylsulfoxide catalyst.
