  • Bronchopleural fistula is a severe complication with a high mortality rate that occurs after pulmonary resection. Several treatment options have been suggested; however, it is a challenge to treat this condition without recurrence or other complications. In this case report, we describe the successful performance of a pedicled latissimus dorsi myocutaneous flap transfer, with no recurrence or donor site morbidity.

  • This study is analyzed by examining the records management systems that are built to use comfortably and manage the records of universities efficiently. This paper analyzed the current status of the records in Chonnam National University (CNU), unit task, function, and organization. As a result, CNU has 127 sections that treat 1,625 unit tasks. The unit task involved in education accounts for 85.91%. The problem is that unit tasks are not organized unequally. It can seem to include some problems in classification and analysis of work when unit tasks are even, more or less, in a particular area. Functional classification in universities are also unequally organized. In universities, functional classification in the field of administration is detailed, while functional classification in the field of research is small in quantity. A more efficient records management will be done if work and function about organization are formed appropriately.

  • The methanol extract of Cinnamoni Cortex showed antibacterial action against cariogenic bacterium, Streptococcus mutans OMZ 176. The active principle of the extract was identified to be trans-cinnamaldehyde, which was bactericidal in the minimal inhibitory concentration (MIC) of $100\;\mu$g/ml against the strain. From the results of antibacterial activity of cinnamaldehyde and its derivatives, the acrolein group in the cinnamaldehyde was elucidated to be an essential element for the activity.

  • In the course of continous work on tubers of Gastrodia elata, a new constituent, 4, 4$^{I}$-dihydroxybenzyl sulfoxide was isolated from the ethyl acetate soluble fraction prepared from the methanol extract. The structure of the compound was identified from the elemental analytical and spectroscopic data in comparison with those of non-substituted benzyl sulfoxide.e.

  • The effective components of Korean ginseng showing the lipid-peroxide depressing activity were isolated. From the ether-soluble acidic fraction of fresh ginseng three phenolic acids were obtained. Salicylic acid and vanilic acid exhibited the potent antioxidant activity, where p-hydroxycinnamic acid did not.

  • Polyhydroxystilbenes including resveratrol were reported to competitively inhibit monoamine oxidase-A-without structural relation with substrates and cynthetic inhibitors for the enzyme. We attempt to explore a plausible mechanism for their inhibitory activity on MAO-A. All the polyhydroxystilbenes tested showed the antioxidant activity on liver homogenate. Furthermore, the antioxidant activity turned out to closely correlate with the MAO-A inhibitory activity.

  • The convergence of libraries, archives, and museums (LAMs) has garnered attention in recent years. Extending the tendency further, National Taiwan Normal University (NTNU) fuses the library, archive, museum, and publisher (LAMP) functionality together in its library. This article elaborates on the LAMP practices of the NTNU Library, which indicates that without creating new units in a university, its library can play a good role of curating invaluable university assets.
