  • Free amino acid in ethanol extracts and total amino acid hydrolysates of Coicis semen were analyzed by amino acid autoanalyzer. The sample A (unpolished Coicis Semen) and sample B(polished Coicis Semen) are used in this experiments. The results obtained from this study are as follows: 1) 17 kinds of free amino acid (Asp, Thr, Ser, Glu, Pro, Gly, Ala, Val, Cys, Met, Ileu, Lew, Try, Phe, Lys, His, Arg,) including 7 kinds of essential amino acid (Val, Lew, Ileu, Thr, Lys, Met, Phe,) as human nutrition were identified and quantified but tryptophan. 2) Total free amino acids of sample A is more than about 3 folds that of sample B. 3) The distribution of free amino acids contained in sample A, threonine is the richiest and then comes Ala, Glu, Asp, and Pro, in that order. In sample B, glutamic acid is the richiest and then comes Thr, Asp, Ala, and Gly, in that order. 4) 17 kinds of total amino acid (Asp, Thr, Ser, Glu, Pro, Gly, Ala, Val, Cys, Met, Ileu, Lew, Tyr, Pher, Lys, including 7 kinds of essential amino acid (Val, Leu, Ileu, Thr, Lys, Met, Phe,) in human nutrition except tryptophan were identified and quanified. 5) Total amino acid content of sample A is more than about 1.06 folds that of sample B. 6) Total amino acid content of sample A in acid hydrolysates is more than about 1.06 folds that of sample B in acid hydrolysates. 7) Unknown chromatogram of ethanol extracts and acid hydrolysates of Coicis Semen were identified as Ornitine.

  • In retrospect, the irony of this story began with the first meeting of these co-authors-in of all places, Coimbatore, India, in 2008, at the 12th International Perforator Flap Course. Here the junior author [hereafter "jp"] demonstrated his unparalleled skills in networking, and soon thereafter journeyed some 11,073 km to Allentown, U.S. to peruse the operating room and clinics of the senior author [sic. ggh] in action. Within 2 years jp orchestrated the presentation of the 14th International Perforator Flap Course, so ggh with great anticipation flew only 6,830 miles to reach Seoul, Korea for his first time. But four years more elapsed before ggh returned again to Korea to be a visiting professor, all the while not quite sure why any Korean would want anything from a country doctor who resided in nowheresville Allentown, Pennsylvania. Yet, an extraordinary fact then was to be unveiled, about which ggh was totally ignorant. The pioneer of plastic surgery in Korea, the first Korean to have completed an accredited plastic surgery fellowship, by coincidence had accomplished all this in . . . . . Allentown. The collegial relationship that evolved between these co-authors, who met by chance, indeed had a precedent coincidence! Was this "by chance" alone or predestination? Amazingly, in a way similar, the origin of plastic surgery itself in Korea also had Allentown connections. As a tribute to Lew Jae-duk, this important story must be here told, so let us now retrace his past in Allentown so we can find how the future was to be not so far away.

  • The omental pedicle based on right gastroepiploic vessels is designed new experimental model for prefabrication(revasculirization) of skin flaps in rats. A $2.5{\times}4cm$ pack of omentum with right gastroepiploic vessels was transferred under a bipediceld panniculocutaneous flap which is $2.5{\times}8cm$ size. At day 7, all four margin was divided and the flap was rasied as an secondary island flap connected only by its vascular pedicle, then the composite flap sutured back in place. The flap perfusion was examined by dermofluorometry and flap survival area was measured at day 12. The Secondary island flap demonstrated a dye fluorescence index(DFI%) of $31.38{\pm}12.33$ and survival rate $80.47{\pm}9.61$ The survival rate was increased when DFI% and contact surface between vascular carrier and skin flap was increased. An india ink injection and histologic examination provided visual evidence of revasculization. The omental pedicle is a promising and safe model for revasculirization of other tissues.
