Abstract: The present invention relates to a 4a-aryldecahydroisoquinoline compound, which is represented by a compound 1, or a pharmacologically acceptable salt thereof. ##STR1## As the results of in vitro and in vivo pharmacological evaluations, it was found that the compounds of the present invention had excellent preventive effects on ischemic death of cerebral neurocytes, suppressive effects on development of cerebral infarction, and strong analgesic and antitussive effects; therefore the compounds of the present invention can be utilized in the medicinal field as a useful cerebral cytoprotective agent, which is aimed at preventing and treating cerebrovascular disorder, ischemic cerebral disorder, cerebral neurocyte disorder, and dementia, an analgesic, and an antitussive.

Abstract: This invention provides a method for manufacturing a resin-coated carrier for an electrophotographic developer comprising the steps of coating the surface of a carrier core which is a dielectric material, with a resin which is also a dielectric material and then baking the thus obtained resin coated carrier core by means of microwave heating under the conditions that a thickness of the resin-coated carrier layer to be baked is in the range of from 5 to 25 mm, the number of revolution of agitating blade for agitating the microwave is in the range of from 20 to 40 rpm and an irradiation time is in the range of from 30 seconds to 10 minutes, to obtain the resin-coated carrier. The resin-coated carriers are characterized by having an excellent durability, excellent resistance to the environment, as well as excellent producibility and economy.
