The double-blind trial of PRL-8-53 in 47 healthy volunteers measured its effects on a variety of cognitive measures. 5 mg of the drug was administered orally 2–2.5 hours before the study tasks.〔 Overall improvements in recollection differed based on how many words were recalled under placebo, with the poor performers (six or less words) experiencing a 87.5-105% increase in recollection and the high performers (eight or more words) a 7.9-14% increase which failed to reach statistical significance; when controlling for subjects over the age of 30 only, a 108-152% increase was noted..〔 No side effects were reported during the trial.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「PRL-8-53」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
