An aniline derivative of the formula (1) ##STR1## wherein R.sup.1 is an eicosapentaenoyl or docosahexaenoyl; R.sup.2 and R.sup.3 are each independently an alkyl or alkoxy having 1 to 6 carbon atoms, or a halogen atom; R.sup.4 is a hydrogen atom, an alkyl or alkoxy having 1 to 6 carbon atoms, or a halogen atom; and A is a single bond, --C(.dbd.O)NH--(CH.sub.2).sub.n --NH-- wherein n is 2 or 3, or a bivalent group of the following formula ##STR2## wherein m and p are each independently 0 or 1. The aniline derivative of the present invention has high inhibitory activity against and high selectivity for ACAT derived from macrophage and is useful as an agent for the prophylaxis and treatment of arteriosclerosis.

Aniline derivative having polyunsaturated fatty acid residue and use

A response characteristics of a microwave spectroscopic measuring system is remarkably improved by supplying a carrier to a continuously flowing sample containing a polar substance to be measured quantitatively. The carrier contains a compound having at least similar chemical form to that of the polar substance.

Method of improving response characteristics of gas sensor using

A gas sample including polar molecules is introduced into a cavity (an internal space) of a cavity resonator, the cavity being provided therein with a Stark electrode which is vertically of a microwave electric field resonating at the microwave frequency, and a direct current Stark voltage which is applied to the Stark electrode together with a sine wave modulation voltage is swept, resulting in a microwave absorption spectrum representing the polar molecules in the gas sample. The resonance frequency of the cavity may be made variable to observe various polar molecules individually.
