摘要： A light curable dental composition is provided. The composition comprises an ethylenic unsaturated compound and a light polymerization initiator. The light polymerization initiator is selected from a combination of an organic peroxide and a pyrylium salt compound of: ##STR1## Wherein R.sub.1, R.sub.2, and R.sub.3 each represents a hydrogen atom, an alkyl group and the like, X stands for an oxygen or sulfur atom and Y for an anionic functional group; a polyperoxy ester containing a benzophenone group; and a combination the polyperoxy ester and an .alpha.-diketone.

摘要： The present invention provides an antipsychotic drug containing essentially an N-acyl amino acid derivative represented by the following general formula:RCO-Awherein R indicates an alkyl or alkenyl having 1-25 carbon atoms, and A is an amino acid residue. The compound is similar to natural products and has little side effect by acting directly to brain cells after passing through easily the blood brain barrier.
