  • The changes of protein bodies in endosperm cells of both seeds with red seed coat and indehiscent seeds of Panax ginseng C.A. Meyer have been investigated in relation to the embryo development. In the early stage of seeds with red seed coat, spherical spherosomes were distributed in endosperm cells. Protein bodies were formed from vacuoles containing the storage protein. Cell organelles were hardly observed in the cytoplasm. In the late stage of the seed with red seed coat, the endosperm was filled with spherosomes and protein bodies. The protein bodies consisted of amorphous inclusions with high electron density or proteinaceous matrix with even electron density. In the seed of in dehiscence, the protein body in endosperm cells contained globoids and protein crystalloids. The globoid of protein body had a electron dense materials. Umbiliform layer was formed between embryo and endosperm. The deformation patterns of endosperm cell wall and the cellulose microfibril were observed in endosperm cells near the umbiliform layer. Umbiliform layer consisted of lipid body and autolyzed cell debris. The protein body of endosperm cell near the umbiliform layer showed various degenerative patterns, and so electron density of proteinaceous matrix was gradually decreased.reased.

  • This study has been carried out to investigate the ultrastructural changes in the associated with the disintegration of the storage materials in endosperm cell of ginseng (Panax ginseng C.A. Meyer) seed during after-ripening with light and electron microscope. The protein body of endosperm cells near the umbiliform layer showed various degenerative patterns, and so electron density of proteinaceous matrix was gradualJy decreased during afterripening. These results indicate that the decomposition of endosperm was already initiated during after-ripening. As the degeneration of endosperm was more progressed after the dehiscence of seed, non-decomposed part of protein body appeared amorphously with high electron density. Decomposed protein bodies were vacuolized with the loss of their matrix and gradually expanded by fusion. Also, spherosomes were gradually dissolved with the lowered electron density during the degeneration of endosperm. The vesicles of dictyosomes near the cell wall are observed in endosperm contacting with umbiliform layer and are fused with plasma membrane. Umbiliform layer which was the complex of the decomposed remnants of lysis and materials has strong stainability for toluidine blue and basic fuchsin.

  • The six phenolic-compound (ascorbic acid, maltol, esculetin,p-coumaric acid, cinnamic acid, and quercetin) contents of Panax ginseng c.A. Meyer were determined in this study. The results showed that the ascorbic acid, cinnamic acid, and esculetin contents of Panax ginseng C.A. Meyer are higher than those of the other ingredients. Among these compounds, ascorbic acid and cinnamic acid significantly inhibited LPS-induced nitric oxide production in the RAW 264.7 cells. Cinnamic acid also effectively inhibited the oxidative damages in the human neuroblastoma SH-SY5Y cells. Although this study examined the neuroprotective and anti-inflammatory activities using only one kind of cells, its results suggest that cinnarnic acid potently contributes to the neuroprotective and anti-inflammatory properties of Panax ginseng C.A. Meyer.

  • The purposes of this study were to determine correlations between the Berg Balance Test (BBS), Timed -UP & Go Test, Fugl Meyer-L/E, Balance, Sensory (FM-L/E, B, S), Motor Assessment Scale-Gait (MAS-G), Comfortable maximal Gait Speed (C MGS), and the Modified Barthel Index (MBI). The subjects were 40 stroke patients of the Korea National Rehabilitation Center in Seoul. Main outcome measures were Balance control (BBS, FM-B), Gait (TUG, C MGS, MAS-G), ADL (MBI) and Motor Function of Lower Extremities (FM-L/E, S). The data were analyzed using Pearson product correlation. FM scales between other clinical and instrumental indexes and multiple stepwise regression analyses were performed to identify prognostic factors for Balance, Gait and ADL Motor Function of Lower Extremity inclinations. The results of this study were as follows: The BBS, FM-L/E, balance, sensory and MBI showed positive correlation relations, but TUG and C MGS showed negative correlations. The sensory factor of the FM-scale showed the strongest variance in predicting BBS. However the FM-balance showed the strongest variance in predicting TUG, MAS-G and C MGS. The use of both quantitative and qualitative scales was shown to be a good measuring instrument for the classification of the general clinical performance of the patients.

  • The major protein (GMP) from the roots of Panax ginseng C. A. Meyer was purified, using gel filtration and ion exchange chromatography followed by reversed-phase and ion exchange FPLC. Staining analysis indicated that the protein has a carbohydrate moiety, which was also shown by band shift experiments using various glycosidases. Electrophoretic and gel permeation studies showed that GMP has an apparent molecular weight of 63 kDa composed of possibly two subunits of 25 kDa containing carbohydrate moiety. GMP showed an anticomplementary activity on the hemolysis of red blood cells, which is a screening tool for inflammation mediator search.

  • The Nuss procedure for the correction of Pectus Excavatum (PE) is associated with intense postoperative pain. Our strategy to control early postoperative pain is to combine epidural with intravenous analgesia. Our aim was to analyse our pain control strategy by reviewing all the PE cases treated at our institution. Sixty consecutive patients, aged between 12 and 26 years old, received the PE operation at our institution from January, 2007 to September, 2010. The median age was 16 (12-27) with a male/female ratio of about 7/1. An epidural catheter was employed in all the cases, with 38 patients (63%) requiring additional drugs to control pain, which remained in place for 74 hours (72-96). The pain score was higher in male patients, but lower in those younger than 16 years old. Moreover, patients that consumed benzodiazepines had a significant decrease in cumulative opioid intake (P = 0.0408). Both gender and age had an impact on pain control, while we noticed a synergistic effect between opiates and tranquillizers.

  • Vessel elements in lateral root, tap root, transition region, stem and mid vein of 1-year old, 3-year old and 5-year old ginseng (Panax ginseng C.A. Meyer) are studied with light microscope to clarify the distribution and differentiation of several kinds of vessel elements. Vessel elements are classified into five types such as ring vessel, spiral vessel, scalariform vessel, reticulate vessel and pitted vessel according to the secondary thickenings of cell wall. All of the five types are not observed in each organ, but diverse kinds of vessels are present in stem and mid vein compared with the underground organs such as tap root and lateral root. The length of vessel elements is longest (680$\mu$m) in stem and shortest (143$\mu$m) in tap root. The diameter of vessel elements is 19.0$\mu$m in tap root and the angle of perforation plate comes under 22$^{\circ}$-60$^{\circ}$. The degree of differentiation of vessel elements according to the length, diameter and angle of perforation plate of vessel elements is highest in tap root regardless of the age of ginseng. Three types of perforation plate such as scalariform, intermediate type of simple and scalariform, and simple perforation plate are observed. The vascular tracheids are characteristically observed in mid vein of 1-year old ginseng, and in transition region of 3 and 5-year old ginseng.

  • Structural changes of the endosperm of Panax ginseng C.A. Meyer from fertilization to germination were investigated by light microscope. The endosperm of the ginseng seed is cellular type. Since endosperm cells adjacent embryo continuously breakdown and disappear with the elongation of embryo, the real of endosperm is gradually decreased. As the anatropous ovules of immature seed with green seed coat developes more and more, ovary cells adjacent ovary cavity become abundant by the periclinal division, their size is decreased, hypotrophy of cell wall discern, and they are gradually differentiated in seed coat. Though embryo responds strongly to basic dye at the stage of completion of endosperm formation, tissue of endosperm responds to acidic dye positively Cell wall of embryo and endosperm are composed of primary cell wall not lignified. Endosperm cells adjacent embryo begin to breakdown in the endosperm tissue of indehiscent seed before the beginning of the after-ripening. Dehiscent seed of which seed coat is opened through after-ripening represent the form as a seedling in the result of embryo developments with the formation of organs; radicle, cotyledon, plumule. Umbilifom layer represents strong positive response to the toluidine blue and the basic function. Umbiliform layer that endosperm cells breakdown and disappear is observed clearly at the periphery of the embryo cotylemon, while slightly at the periphery of the radicle.
