The study is to synthesize dual-site phase-transfer catalyst, and use it to form tri-liquid phases, and investigate the catalytic benzoylation of 4'-hydroxyacetophenone sodium salt and benzoyl chloride to produce 4-acetylphenyl benzoate in ultrasound-assisted tri-liquid-phase system.

Methods: Between May and July 2007, 5 patients (4 female and 1 male patients) with perineal or coccygeal pain were recruited. A sacral transverse view and longitudinal view with high resolution ultrasound probe (5~12 MHz) were defined in the sacral cornua and the first cleft below the sacral hiatus was found.

使用5~12MHz高解析度超音波探头，以横切及纵切呈像先找出sacral cornua，再找出sacral hiatus后可见的第一个裂缝。
