A new technique for the preparation of a highly clear and transparent emulsified aqueous solution containing immiscible monomer droplets with diameters of a few tens of nanometres under surfactant-free conditions using tandem acoustic emulsification is described. Highly conductive transparent polymer films were successfully prepared from such an emulsified solution.

In the present study, we investigated the role of 5-hydroxytryptamine type 3 (5-HT(3)) receptors in hypnosis and analgesia induced by emulsified sevoflurane. A mouse model of hypnosis and analgesia was established by an intraperitoneal or subcutaneous injection of emulsified sevoflurane.We intracerebroventricularly (i.c.v.) or intrathecally (i.t.) administered YM-31636, a 5-HT(3) receptor agoni...
