Major findings of this study are as follows. First, in a science-based area such as drug development, the core of successful knowledge creation lies in creative combination of different bodies of scientific explicit knowledge. Second, the greater the difficulty of learning external knowledge, the more tacit knowledge is needed for the recipient firm to effectively exploit that knowledge. Third, in science-based sector such as pharmaceutical industry, the key for successful knowledge creation lies in the capability of recruiting and retaining star scientists. Finally, for effective knowledge creation, a firm must keep its balance among three dimensions of organizational capabilities: local, process, architectural capabilities.

  • Nine phenolic ($1\~9$) and two furan type (10, 11) compounds, were isolated from the methanolic extract of the tuber of Gastrodia elata Blume (Orchidaceae) in the course of continuing search for platelet anit-aggregating plant components. Compound 1 was identified as 4,4'-dihy-droxybenzyl sulfone, a novel compound for the best of our knowledge. Compound 10, 5-hydroxymethyl-2-furancarboxaldehyde, was isolated for the first time from this plant. Compound 1 ($IC_{50};\;83{\mu}M$) was about four times more inhibitory to U46619 induced aggregation than ASA ($IC_{50};\340{\mu}M$). Compound 9, 4,4'-dihydroxy-dibenzylether, ($IC_{50};\;5{\mu}M$, $3{\mu}M\;and\;33{\mu}M$, respectively) was $10\~}80$ fold more potent than ASA ($IC_{50};\;420\;{\mu}M,\;53\;{\mu}M\;and\;340\;{\mu}M$ respectively) to collagen, epinephrine and U46619 induced aggregation, although it is less active than ASA to AA induced aggregation.

  • This study investigated the disinfection effect of monopersulfate (MPS) compound against white spot syndrome virus (WSSV) by bioassay using kuruma shrimp (Marsupenaeus japonicas). A WSSV stock was prepared with muscle homogenate from WSSV-infected whiteleg shrimp (Penaeus vannamei) and its lethal dose 50% endpoint (LD50) and infectious dose 50% endpoint (SID50) were respectively determined as 10-5.63 and 10-6.79 in bioassay using kuruma shrimp, followed by PCR assays. The disinfective effect of MPS compound (1.2 ppm, 2.4 ppm, 4.8 ppm) was performed by bioassay using about 10-fold higher dilution (10-4) of WSSV homogenate. The compound resulted in WSSV inactivation by a concentration-dependent manner. In addition, 4.8 ppm of MPS completely prohibited WSSV infection. To our knowledge, this study is the first report about the usefulness of MPS as a disinfectant to WSSV.
