  • Purpose: To analysis of the result of the treatment of metastatic diaphyseal fracture of the humerus with closed interlocking intrameduallry nailing. Materials and Methods: Among surgically treated 29 patients with pathologic or impending fracture of diaphysis of the humeurs, 13 patients (16 cases) treated with closed intramedullary interlocking nail were selected for the study. The final result of pain relief and functional recovery was evaluated by modified rating system of Perez et al. Results: Primary cancer was diagnosed after fracture was developed in 2 patients and pathologic or impending fracture was occurred average period of 28.9 months after primary cancer was diagnosed. The main primary malignancies were multiple myeloma, lung cancer and breast cancer. Mean survival after humeral metastasis was 11.7 months. The final result was superior to fair in 13 of 16 cases, and poor in 3 cases with progression of tumor spread or distant dissemination to the ipsilateral fingers. Except the latter 3 patients and other 3 patients, who died before 3 months postoperatively, bony union was achieved in 10 cases. There were no complications related to surgery. Conclusion: Closed interlocking intrameduallry nailing is accomplished with brief operative time, small amount of bleeding and provides immediate stability with resultant early return of function to the arm. Additionally it allows early postoperative irradiation. However, some of our cases shows that intramedullary nailing can accelerate tumor spread and metastases elsewhere, so that serious consideration must be given in planning this treatment. In conclusion, the functional status before fracture, life expectancy, type of tumor and extent of involvement should be carefully considered to decide operative treatment of metastatic disease.

  • This research was conducted to present reference data to be used as newly reclaimed tidal land management. We investigated vegetation succession at 4 reclaimed/reclaiming project areas and discussed relationship with soil and vegetation trhrough investigation and analysis soil chemical characteristics at 2 areas. 14 families 58 kinds were investigated. Vegetation were variou at Dea-Ho conservation polt and Seok-Mun National Industrial Area which are maintaining naturally. Vegetation were simple at Hong-Bo and Dongjin and MinKyong river areas which effected sea water. Common species that were investigated at 9 sites were Suaeda asparagoides, Aster tripolium, Phragmites australis, Suaeda maritima, Suaeda japonica, Carex scabrifolis. As soil desalinization progressing, soil classified at first saline-soidc soil, the nest saline soil and then normal soil. Chenopodiaceae revealed at about 30 dS/m of soil ECe and existed to 10 dS/m of soil ECe. At about 20 dS/m of soil ECe. Aster tripolium, Calamagrostis epigeios, and Sonchus brachyotus revealed and then non-halophytes and common plants at inland revealed at low soil ECe of about 10 dS/m. However it was not to progress vegetation sucdession and soil desalinization at the same time, owing to input of seeds or plants ect from out-ecosystem. So for promotion of vegetation at newly reclaimed tidal land, we proposed that it was very effective to plant artificially halophytes or suitable species through soil test.

  • The aim of this study was to define the toxic effects of phenanthrene (PAHs) on the fertilization and normal embryogenesis rates in the two species of sea urchin (Hemicentrotus pulcherrimus and Mesocentrotus nudus). The sperm and fertilized eggs of both sea urchin species were exposed to serial dilutions of phenanthrene for 10 min and 48 hours, respectively. The fertilization rate and normal embryogenesis rate of H. pulcherrimus and M. nudus were decreased in a concentration-dependent manner. The EC50 for the fertilization rate of H. pulcherrimus and M. nudus was 17.48 mg L-1 and 16.21 mg L-1, and the EC50 for the normal embryogenesis rate was 2.99 mg L-1 and 0.36 mg L-1, respectively. Between the two species, H. pulcherrimus was more sensitive to phenanthrene exposure, and 48 h normal embryogenesis was the more sensitive endpoint. Therefore, the results of this study demonstrated that the exposure of both sea urchin species to phenanthrene caused alterations in egg fertilization and the early developmental stages.

  • This study was conducted to select some useful plants as functional material candidates. A total of 38 plants were preliminarily screened for the anti-inflammatory and antioxidant activities. The preliminarily selected 8 plants were further investigated to verify the in vitro inhibitory effect on inflammation and oxidative stress. Boehmeria platanifolia (root), Carpinus coreana (branch), and Eupatorium japonicum (leaf) inhibited the expression of inducible nitric oxide synthase (iNOS) in lipopolysaccharide (LPS)-treated RAW 264.7 cells. Eupatorium japonicum (leaf) suppressed the expression of cyclooxygenase-2 (COX-2), whereas Boehmeria platanifolia (root) and Prunus yedoensis (branch) inhibited the transcription of nuclear factor-kappa B (NF-${\kappa}B$). Treatment with the extracts ($2.5{\sim}20{\mu}g/ml$) of Abutilon theophrasti (leaf, flower/seed) and Hemistepta lyrata (stem) did not show toxicity on RAW 264.7 cell proliferation, but treatment with $2.5{\mu}g/ml$ of Boehmeria platanifolia (root) exhibited cell toxicity. Carpinus coreana (branch) and Prunus yedoensis (branch) showed potent scavenging activities on peroxynitrite. Akebia quinata (flower), Carpinus coreana (branch), and Prunus yedoensis (branch) effectively inhibited reactive oxygen species (ROS). Abutilon theophrasti (leaf), Boehmeria platanifolia (root), Carpinus coreana (branch), and Eupatorium japonicum (leaf) exhibited strong inhibitory capacity with regard to nitric oxide (NO) production. The results suggested that Abutilon theophrasti (leaf) has in vitro anti-inflammatory and antioxidant activities, and that is a useful functional material candidate.

  • A bronchus-associated lymphoid tissue(BALT) lymphoma of the lung is a rare disorder of patients with Sj$\ddot{o}$gren's syndrome. A 49-year-old woman was admitted for an evaluation of exertional dyspnea and general weakness which had persisted for two years. The patient had suffered from dry mouth and dry eyes for five years. The physical examinations showed a coarse breath sound with inspiratory crackles on the whole lung field, particularly on the both basal lungs. The laboratory data disclosed high titers of anti-nuclear antibodies, and anti-SSA (Ro), and anti-SSB (La) antibodies. Chest radiographs demonstrated the presence of bilateral, diffuse, reticulonodular densities in both lungs. Thin-section CT scans showed diffusely distributed mosaic pattern of an inhomogeneous attenuation extending over the entire lung zone. The histological findings from an open-lung biopsy specimen revealed an accumulation of lymphoid cells around the bronchioles and an extension of malignant lymphoma cells from the bronchiolar epithelium toward the alveolar space. Immunohistochemically, the neoplastic cells reacted positively to the CD 20 antigen and were focally positive for the UCHL 1 antigen. The histological diagnosis was consistent with a low grade marginal zone B-cell lymphoma originating in the BALT. Here, we present a case of a histologically proven BALT lymphoma of the lung in a patient with primary Sj$\ddot{o}$gren's Syndrome.

  • Alcohol metabolizing and antioxidant activity of Mentha species were investigated in rat liver. Fifty six Sprague Dawley rats were randomly divided into seven groups such as normal (ethanol excluded), negative control (40% ethanol (10 g/kg of body weight/day) fed), positive control (1 g Silymarin/kg of body weight/day with ethanol fed), two Mentha viridis extracts (0.2 g & 1 g M. viridis methanol ext./kg of body weight/day with ethanol fed) and two M piperita extracts (0.2 g & 1 g M. piperita methanol ext./kg of body weight/day with ethanol fed) groups. After 2 weeks, rats were sacrificed under ether. The activities of alcohol dehydrogenase (ADH), aldehyde dehydrogenase (ALDH), catalase (CAT), manganese superoxide dismutase (Mn-SOD), glutathione peroxidase (GAH-px) and the content ofthiobarbituric acid reactive substance (TBARS) in the rat livers and the activity of glutamate pyruvate transferase (GPT) in serum were evaluated. From the analyses, 1 g M. viridis and 0.2 g M. piperita administrated groups showed higher ADH and ALDH activity than the other groups. Groups fed with 0.2 g and 1 g M. viridis ext. and 0.2 g M. piperita ext. showed higher CAT activity than the other groups. All the Mentha extract fed groups exhibited more effective in recovering Mn-SOD, GSH-px and GPT acitivities to a similar degree of normal group. TBARS contents of two M. viridis ext. fed group and 0.2 g M. piperita ext. fed group were higher than those of the other groups. M. viridis extract fed groups showed more effective in CAT and Mn-SOD activities than M. piperita extract groups at p < 0.05. Finally, it is concluded that both Mentha species have alcohol metabolizing and antioxidant activity and M viridis is more effective than M. piperita.

  • A Total of 48,101 performance records of sows for Yorkshire and Landrace breeds were collected from swine breeding farms in Korea from 2001 to 2008. A general ingredient analysis included the fixed effects of breed, parity, year, season, and farm. For the number of heads per 1st parity analysis by each growth traits, the data of 48,101 heads was used to analyze growth traits group. In the general ingredient analysis, the results showed high significance except for lean percentage by season (p<0.05). Average daily gain of Landrace breed ($640.48{\pm}0.749g$) was better than that of Yorkshire breed ($624.22{\pm}0.608g$), and the backfat thickness of Yorkshire breed ($13.44{\pm}0.030mm$) was thicker than that of Landrace breed ($12.50{\pm}0.037mm$). For the number of born alive and number of stillborn by growth traits for each breed, number of born decreased after test end day of 161 to 165 day, and average daily gain of 620 g to 640 g and the highest number of born appeared at the backfat thickness of 13 mm to 14 mm for yorkshire breed. In case of Landrace breed, number of born was the highest, and the number of stillborn increased together with average daily gain. The number of born was high when backfat thickness was less than 11 mm. The number of born trended to decrease when backfat thickness increased.
