By studing on selection of optimal media and nutrient concentration in selected media so that carried out the influnance of bulb enlargment and quality of cut flower of hydroponicsis of lily. The result is following. 1. The sprouting was relatively fast in husk+peatmoss, perlite+peatmoss and, according to cultivars its rank was cv.Cherry Blossom, cv. Nove Cento, cv. Snow queen. The peroid of growing was short appromaxitively forty day in cv. nove cento, twenty day in cv.Snow Queen than that of spring planting. The quality of cut flower, that is plant height and number of flowers was excellent in fermented husk+fermented saw dust(7:3). 2. In the case of growing late, not only fresh weight increased remarkable but also degree of bulb enlargement revelaed greatly, when growing point of new bulb was differentiation. 3. The rate of bulb enlargement was remarkable difference between treatment according to nutrient concentration ; bulb weight , bulb diameter, bulb height, bulb width, number of scale and scale weight were very excellent in twofold standard soultion of Horticultural Experiment (N,30-P,6-K,12-Ca,16-mG,8me/1). 4. The quality of cut flower according to nutrient concentration, that is cut flower weight, cut flower height and leaf area were good when cv. Casa blanca was treated by standard soultion of H.E (N,15-P,3-K,6-Ca8-Mg,4me/l),cv. Elite was 1/2standard soultion of H.E.(N,7.5 -P, 1.5-K,3-Ca,4-Mg, 2ME/L) Gelria treated with twofold standard soultion of Horticultural Experiment was excellent in all of them above, but revealed bad for hardness of stem in the cv. casa blanca cultivars. 5. As a result of leaf analysis, all of cultivars revealed highly in rate of absorbance of nitrogen and potassium, when nutrient of high-concentration was treated Amount of absorbance of them remarkable increased in caseof cv. Elite cultivar, especilly absorbance of calcium was higher than other component. Amount absorbance of nitrogen in cv.casa blanca, according to high-concentration nutrient was much better but rate of absorbance of potassium weakly increased. Conseqencelly we know that nitrogen and potassium play an imporitant role in bulb enlargement and quality of cut flower. 6. The quality of bulb like bulb weight, bulb diameter, bulb width, bulb height, number of scale, scale weight were execellent as it cut thestem at 10 cm above the ground to reuse a bulb after cut flower.

Hepatocellular carcinoma frequently metastasizes through direct extension, lymphatic, and hematogenous routes. The most common sites of metastasis are the lungs and the lymph nodes, glands, bones, spleen, kidneys, colon, and pleura are the sites of metastasis in decreasing order of frequency. But metastasis to the ovary is very rare. It is thought that metastasize to the ovary occurs through infiltration or dissemination. However, we observed ovarian metastasis of primary hepatic tumor in a 34-year old female who suffered from lower abdominal pain. At first, it was diagnosed as a primary ovarian tumor. But histologically, it presented sinusoidal pattern surrounded by the tumor cells and contained rounded by the tumor cells and contained round hyaline globules in minority of the cytoplasm. Then, the histologic features of percutaneous, sono-guided liver biopsy speecimen of the liver mass are similar to those of resected ovarian tissues. Therefore, we concluded that ovarian tumor was originated from hepatocellular carcinoma. In summary, this report examines a case of hepatocellular carcinoma with ovarian metastasis in a female and reviews the literature.

The Yo stream(drainage area: 526.08㎢, length: 52.0㎞) is one of the branchs of the Seom Jin river. In order to evaluate effects of the sewage in Nam-Won City(I) on the water pollution of the Yo stream, water qulity analysis and estimate the pollutant discharge rate were carried out at six sites in the Yo stream basin from December 1994 to September 1995. The results of research are summarized as follow: 1. According to the water quality of six sites evaluated by BOD, ST1 is classified into I grade, ST2 and ST3 are II grade, ST4∼ST6 sites are III grade. 2. Amount of total BOD load from the Yo stream basin was estimated 11,810㎏/day of which 13.9% was contributed by land, 0.1%, was contributed by industrial waste water, 43% was contributed by population and livestock, respectively. 3. As Nam-Won city(I), discharge rate and effluence rate of BOD, SS were estimated 28.4%, 10.6% and 20.6%, respectively. 4. Since Nam-Won city sewage treatment plant started operation, BOD, SS reduction rate of Nam-Won city(I) were forecasted 36.1% and 20.6%, respectively.

Background: Spontaneous or interferon-induced HBsAg seroclearance is durable in most patients with chronic hepatitis B (CHB). However, little is known about the durability of HBsAg seroclearance following nucleoside analogue (NUC) therapy. Methods: Among 4,578 patients who were treated with either lamivudine (n=1,924) or entecavir (n=2,654) at a tertiary referral hospital in Korea between 2000 and 2010, 121 achieved HBsAg seroclearance. Fifty-eight patients were included in this study after exclusion of 63 patients; acute hepatitis B (n=19), hepatocellular carcinoma (n=8), prior treatment with interferon (n=6), prior immunosuppressive therapy (n=17), liver transplantation (n=6), follow-up loss immediately after HBsAg seroclearance (n=5), and continued NUC therapy (n=2). Results: Mean age of 58 patients were 42 (SD 11) years and 41 (71%) were males. All were assumed to have HBV genotype C. At the initiation of NUC therapy, median levels of ALT and HBV DNA were 153 IU/L (interquartile range [IQR], 48-340 IU/L) and 7.0 log10 copies/mL (IQR, 3.8-8.0 log10 copies/mL), respectively. Twenty-seven (47%) had HBeAg. The median duration of NUC therapy (56 with lamivudine and 2 with entecavir) before HBsAg seroclearance was 42 months (IQR, 24-66 months). During a median follow-up period of 20 months (IQR, 12-32 months), HBsAg reversion occurred in 5 of 58 (8.6%) patients. Three of those 5 patients achieved re-clearance of HBsAg without treatment during further follow-up. The other 2 patients remained HBsAg-positive, but with low titer (< 1.0 IU/mL) and undetectable HBV DNA by PCR. Virologic recurrence (detectable HBV DNA by PCR) occurred in 12 of 58 (20.7%) patients. However, all of these patients maintained HBV DNA <10,000 copies/mL. No patient experienced biochemical relapse (ALT flare > x5 ULN). Conclusion: HBsAg seroclearance following NUC therapy is rare but durable in most patients with CHB after treatment discontinuation. Therefore, HBsAg seroclearance would be an ideal treatment endpoint during NUC therapy.

Untranslatable Coat Protein RNA - Mediated Potato Virus Y Resistance in Tobacco Plants
Lee, Yung Gi,Lee, Cheong Ho,Kang, Shin Woong,Pak, Eun Kyung 한국유전학회 1997 Genes & Genomics Vol.19 No.4
Total viral RNA was purified from potato virus Y-necrotic strain (PVY-VN) which was isolated from Nicotiana tabacum var. Burley 21. Coat protein (CP) cDNA fragment which has starting and termination codons, was synthesized by RT-PCR. PVY CP cDNA was manipulated to untranslatable form by megaprimer PCR method and confirmed by DNA sequencing. The untranslatable CP cDNA was inserted to plant expression vector (pPEV-6) and was transformed to Nicotiana tabacum cv. NC82 by Agrobacterium-mediated transformation. The untranslatable PVY CP cDNA transformed plants were regenerated on MS media containing 100 ppm kanamycin. Highly resistant plants to the PVY were selected based on symptom development after mechanical inoculation in a greenhouse. By the genomic PCR and Southern blot hybridization, it was confirmed that the untranslatable CP cDNA fragments were integrated into genome of transformed tobacco plants which showed high resistance to PVY-VN with one to three copies of the transgene.
