  • Cilostazol. a quinolinone derivative that inhibits phosphodiesterase. is used for the treatment of intermittent claudication resulting from peripheral arterial disease. In order to perform pharmacological and pharmacokinetic studies of cilostazol, specific. sensitive and reproducible analysis methods are demanded. Therefore. in the present study. an analytical method of cilostazol in human plasma was developed using semi-microbore HPLC equipped with automated column switching system. (omitted)

  • Two compounds were newly isolated from the leaves of Aloe barbadensis Mill. Their strucutres were identified as 3, 4-dihydro-3, 9-dihydroxy-8-methoxy-3-methyl-1(2H)-anthracenone(1) and 10-.betha.-D-glucopyranosyl-1, 80, 10-trihydroxy-3-(hydroxymethyl)-(R)-9(10H)-anth racenone(2) by chemical and spectral evidences.

  • We report the rare case of a 58-year-old woman who was diagnosed with fungal empyema thoracis combined with osteoradionecrosis. After 32 months of home care followed by open window thoracostomy, thoracoplasty with serratus anterior muscle transposition and a latissimus dorsi myocutaneous flap was performed successfully. Although thoracoplasty is now rarely indicated, it is still the treatment of choice for the complete obliteration of thoracic spaces.
