Abstract: Disclosed are a method of measuring ESR in a sample located outside a resonator using the B1 leaking to the exterior from the end of the resonator; and an ESR device comprised of at least a resonator capable of applying a B1 leaking from the end of the resonator to a sample located outside the resonator, and a magnet located on the resonator side of a plane containing the end of the resonator that is capable of applying a B0 and a modulation field. These inventions enable ESR measurement of the interior of large samples.

Abstract: Drugs or reagents containing as the active ingredient N-acyloxylated cycloalkyl compounds represented by general formula (I):
wherein A is optionally substituted C4 or C5 cycloalkyl which may have one double bond in the ring; and R is C1-C3 alkyl or phenyl). The above compounds are hydroxyamine derivatives functioning as spin trapping agents and can rapidly react with free radicals or active oxygen in an objective organ in spite of their being excellent in stability during the preparation or administration thereof.
