We studied the expression of the cell surface antigen associated with myeloid and lymphoid leukemias on bone marrow or peripheral blood blast cells from 153 leukemic patients including 61 cases of acute myelogenous leukemias(AML), 46 of acute lymphocytic leukemias(ALL) and 12 of acute leukemias. They were analyzed by direct or indirect immunofluorescence method for reactivity with the monoclonal antibodies to B cells(CD10, CD19, SmIg), T cells(CD2, CD5, CD7, CD3, CD4, CD8), myeloid antigen(CD13, CD14, CD33, CD61) and a nonspecific antigen, HLA-DR. Lymphoid associated markers detected on AML is CD7 32.8%, CD10 14.8%, CD5 13.1%, CD2 6.6% and CD19 1.6%. TdT was positive in 4.9% of AMLs. Hybrid leukemias were 8 cases out 61 AML cases and were mainly composed of monocytic lineage, M4 and M5a. Myeloid markers detected in ALL were CD13 2.2% and CD33 2.2%. In this study, immunologically classified ALLs were composed of 65.2% of CALLA (+) B precursor type, 10.9% of CALLA (-) B precursor pattern, 8.7% of T cell type, 2.2% of B cell type, 4.5% of mixed lymphoid lineage(B&T), 2.2% of undifferentiated leukemia, and 6.5% of hybrid leukemia. Twelve cases of acute leukemias ware finally diagnosed to be 5 cases of hybrid leukemia, 3 cases of B lineage, 3 case of T lineage and 1 case of mixed lymphoid(B&T) leukemia. In summary, we think the best method for typing acute leukemias is by using a combination of FAB classification and immunophenotying.

The new white calla lily (Zantedeschia aethiopica) cultivar 'White Cutie' was bred at the National Institute of Horticultural & Herbal Science (NIHHS) in 2011. 'Childsiana' showing the multi-flowering characteristic and 'Wedding March' resistant to soft rot disease were artificially crossed in 2004. Of the progeny, 'White Cutie' was selected specifically for use in cut flower production after investigation over seven years (2005 to 2011) of genetic and phenotypic characteristics, resistance against soft rot, and customer preference regarding the culture vigor and post-harvest quality. 'White Cutie' was early flowering (85.6 days to flowering) with white flowers (RHS W155C), although it had a mid-sized flower in which spathe height and width were 8.6 cm and 8.7 cm, respectively. It was multi-flowering (6.2 flowers per plant) and produced a very high number of cormels (13.4 per plant). Furthermore, it was resistant to soft rot disease.

To establish rapid micropropagation through organogenesis from apices-derived callus or direct adventitious shoot of three calla lily cultivars(Zantedeschia spp, cv. Sunlight, cv. Chiante, cv. Pink Persuation) were cultured on Murashige and Skoog medium supplemented with different plant growth regulators. The formation rate of callus, organogenesis and in viかo tuber production among the three cultivars were tested. Callus was obtained from cvs. Sunlight, Chiante and Pink Persuasion; the best cultivar was Sunlight. Sunlight induced $53.3\%$ callus and Chiante had the highest rate of $56.7\%$ direct shoot regeneration on medium with 2.0 mg/L BA. Regeneration frequencies ranged from 20 to $70\%$ on medium with 2.0-3.0 mg/L BA. The highest percentage of regeneration and the greatest number of shoots were obtained on medium containing 3.0 mg/L BA in three cultivars. Cytokinins induced multiple shoot formation; 1.0 mg/L of 2ip, 5.0 mg/L of BA, and 1.0 m/L of BA induced 16, 14 and 12 multiple shoots in cvs. Sunlight, Chiante and Pink Persuasion, respectivly. 1.0 mg/L of IAA enhanced root growth in cvs. Sunlight and Chiante while cv. Pink Persuasion exhibited enhanced root growth at 2.0 mg/L of IBA. NAA, however, induced no change in root growth. The addition of 90 g/L sucrose enhanced in vitro tuber formation and following tuber expansion in cv. Sunlight, while 70 g/L of sucrose was effective in cvs. Chiante and Pink Persuasion.

Objective of this Research was to determine the influence of foliar application of $CaCl_2$ or $K_2SI_2O_5$ and soil application of $CaCO_3$ or $SiO_2$ on growth and cut flower quality of Zantedeschia aethiopica 'Wedding March'. To achieve this, $CaCl_2$ or $K_2SI_2O_5$ were applied at six leaf stage with the concentration of 0.05, 0.1 and 0.2% and $CaCO_3$ or $SiO_2$ were applied as basal fertilization with the amount of 100, 200, 400kg per 10a or 50, 100, 200, 400kg per 10a respectively. Plant material was used Zantedeschia aethiopica 'Wedding March'. Among calcium chloride($CaCl_2$) and calcium carbonate($CaCO_3$), calcium chloride foliar application was more effective than calcium carbonate with basal fertilization to growth of common calla 'Wedding March'. In the 0.1% solution foliar application of calcium chloride, plant height, leaf length and length of cut-flower was more longer than control. Length of leaf petiole was more longer and leaf fresh weight was more heavier than control. The degree of petiole hardness was more effective in the 0.1% solution calcium chloride foliar application than any other treatment. In the silicate fertilization treatment, plant height of 50kg per 10a treatment was most highest as 73.9cm. also its length of leaf petiole and leaf fresh weight was more effective than any other treatment. The hardness of petiole was better in the 50kg per 10a silicate fertilizer treatment. The cell shape of leaf petiole was round and tissue was regular in the treatment of 0.1% calcium chloride and 50kg per 10a silicate fertilizer but the cell of control was irregular round type. Macro element content of calcium was more amount in the treatment of silicate 50kg per 10a basal fertilization. The infected ratio of Erwinia was no relation with lime and silicate fertilizer treatment. Lime fertilizer treatment is effective for growth and flowering of Calla than silicate fertilizer and the suitable concentration was 0.1%.

Ed- the file appears to be corrupted, and in many sections (these are highlighted) I cannot read it. I presume it has been copied from another format, maybe Hangul 2004. The purpose of this study was to determine a method of make-up image extraction from specific paintings and also to create cyber make-up models according to the images. For this study, Georgia O'Keeffee's floral paintings were analyzed and their colors were compiled to make color palettes. This study attempted to approach floral image make-up which applies specific paintings through the digital mode in the manner of computer graphics. The results of this study were as follows: First, we found romantic images, including feminine, lovely and soft images by Y, GY and RP group colors, in 'Two Calla Lillies on Pink'. Second, we found modem images, including urban, up-to-date and cool images by G, GY and B group colors, in 'Blue and Green Music'. Third, we found sexy images, including brilliant, tempting and daring by R, B and G group colors, in 'Music-Pink and Blue'. To summarize, the images of the paintings were similar to those of the make-up models.

The effects of the hindered and non-hindered water soluble long-chain disulfide bonds on the stability and cytotoxicity of the ricin A chain (RTA) immunotoxin were examined. The RTA immunotoxins were prepared with the Fab fragments of anti-common acute lymphoblastic leukemia antigen (CALLA) monoclonal antibody (Fab-RTA) using sulfosuccinimidyl-6-[(-methyl-(-2-pyridyldithio)toluamido]toluamido]hexanoate (S-LC-SMPT) and sulfosuccinimidyl-6-[3-(2-pyridyldithio-propionamido]hexanoate (S-LC-SPDP). The prepared Fab-RTA immunotoxins were evaluated for their conjugation yield, immunoreactivity, thermal and disulfide bond stability and cytotoxicity. The conjugation yield of the Fab-RTA immunotoxin from the water soluble long chain crosslinking agents, S-LC-SMPT and S-LC-SPDP, were comparable. Both Fab-RTA immunotoxins exhibited a similar immunoreactivity and thermal stability in aqueous solution. However, S-LC-SMPT -mediated Fab-RTA, sterically hindered, showed an enhanced disulfide bond stability in vitro over S-LC-SPDP mediated one. In the cytotoxicity against antigenic cell Daudi, the S-LC-SMPT -mediated RTA immunotoxin maintained a comparable cytotoxicity, compared with S-LC-SPDP mediated Fab-RTA immunotoxin.

Purpose : p16 gene, mapped to the 9p21 chromosomal region, has emerged as a candidate tumor suppressor gene in human neoplasm. It is an inhibitor of cyclin-dependent kinase and inhibits Rb phosphorylation. In a variety of tumors including childhood acute lymphoblastic leukemia (ALL), deletion and/or mutation of the p16 gene has been found. Despite their high frequency, the prognostic importance of p16 alterations is still controversial in ALL and has been reported to be either unfavorable or similar to that of other patients. We studied the correlation between loss of p16 protein confirmed by immunohistochemical staining and clinical outcomes of patients diagnosed as ALL. Methods : We performed an immunohistochemical staining for p16 protein in 74 cases of bone marrow biopsy slide initially diagnosed as ALL between January 1998 and December 2006. We reviewed the clinical manifestations, laboratory findings, treatment outcomes retrospectively. Results : Of 74 slides, 12 were negative for p16 protein. Seven were males and 5 were females with a median age at diagnosis was 5.8 (1.3-18.8) years. Initial WBC were 17,225 $(500-403,300)/{\mu}L$. By immunologic surface marker analysis, 7 patients were early pre-B CALLA (+) and 5 patients were T-cell ALL. Two patients of intermediate risk group had relapsed and died. Three patients had family history of breast cancer. Four patients died and overall survival rates were $53.5{\pm}18.7%$. Conclusion : Loss of p16 protein is supposed to be an independent risk factor of childhood ALL associated with poor outcomes. In clinical setting, the clinician must take into account p16 status, not only at the genomic but also at the protein level. Further clinical experience on thoroughly investigated cases will help a better understanding between p16 status and clinical outcomes.
