Abstract
PURPOSE To assess the changes in intraocular pressure (IOP) with age in South Korea. METHODS Subjects aged 20-79 who had been receiving health examinations at a university hospital were enrolled. They completed physical and ophthalmic examinations. Subjects with ocular disease that could possibly affect their IOP were excluded. The relationships between IOP and age, blood pressure, heart rate, body mass index, blood chemistry, and electrolyte were analyzed using a linear mixed model. RESULTS Of the 33 712 subjects, 31 857 participants were enrolled. In a cross-sectional analysis, IOP also showed a negative correlation in all age groups (respectively, P<0.001). In particular, patients in their 60s~80s had a less steep decreasing slope of IOP with age than patients in their 20s~30s (correlation coefficient -0.260 and -0.168, respectively). In longitudinal analysis, negative trend was shown in the slope of tendency in total subjects. When analyzing the effect of gender on the relationship between age and IOP, females had a less steep decreasing slope of IOP with age than males by 0.05 mm Hg. With regard to systemic parameters, systolic blood pressure and heart rate were positively correlated with IOP (P<0.001). CONCLUSION IOP was significantly decreased with age, although the amount of change was small. In women and older age groups, IOP was less decreased than that of men and young age groups. In addition, IOP was positively associated with systolic blood pressure and heart rate.

Abstract
Although cardiac stem cells (CSCs) have emerged in regeneration research, the number of isolated CSCs is low, making a sufficient supply of functional elements an important consideration in cardiovascular research. In this study, we established an efficient method for CSC isolation. We directly compared cultures of single cells to human cardiac-derived c-kit-positive progenitor cells (hCPCs(c-kit+)). The two protocols employed enzymatically digested hCPCs(c-kit+) (ED-hCPCs) with tissue-expanded hCPC(c-kit+) (TE-hCPCs). Using fluorescence-activated cell sorting, we showed the concentration of c-kit in TE-hCPCs to be higher than in ED-hCPCs, although the total number of c-kit positive cells resulting from ED-hCPCs was similar to that resulting from TE-hCPCs. The cardiomyocyte-associated proteins, GATA4 and Nkx2-5, which were expressed during hCPCs expansion, did not differ between the isolation methods. Importantly, the expression of the CSC stem cell marker, c-kit, was more efficiently preserved using the ED-hCPCs versus the TE-hCPCs method. In a cell proliferation assay, the ED-hCPCs method produced a significantly greater number of cells. Finally, hCPCs derived using both protocols differentiated into endothelial, smooth muscle, and cardiomyocyte lineages. In conclusion, the single-cell culture protocol using an enzymatic digestion method may be more useful to isolate human cardiac-derived c-kit-positive elements compared with the tissue expansion method.

Abstract
4064 Background: Weekly irinotecan, cisplatin, and concurrent radiation therapy is a well-tolerated, active regimen in locally advanced esophageal cancer. (Ilson. JCO 2003) Cetuximab, an EGFR inhibitor, is a potent radiation sensitizer in head and neck cancer. (Bonner. Proc ASCO 2004) Methods: In this phase II trial, patients (pts) with T2–4N0–1M0–1A esophageal adenocarcinoma (A) or squamous cell carcinoma (S) receive 5040 cGy/28 fractions of radiation therapy (RT) and concurrent weekly cisplatin 30mg/m2 plus irinotecan 65 mg/m2 on weeks 1, 2, 4, and 5, followed by surgery 4–8 weeks after completion of RT. Additionally, pts receive weekly infusions of cetuximab 250 mg during RT, up to one week before surgery, and for 6 months following surgery. Results: Seventeen pts have been entered: male: female = 14:3, median age 54, ECOG PS 0:1 = 6:11, A:S = 17:0, stage IIA:IIB:III:IVA = 6:1:8:2, tumor location-esophagus-mid:lower:gastroesophageal junction = 1:4:12, >10% weight loss-yes:no = 8:9. Of 17 pts entered, 15 pts have proceeded to surgery, 1 pt died from Aspergillus infection resulting in respiratory failure and sepsis, and 1 pt is pending surgery. Of the 15 pts who underwent surgery, 2 (13%) had a complete pathologic response; pathologic stage for other pts: 0 = 1, I = 3, IIA = 3, IIB = 1, III = 4, IV = 1. Grade III/IV toxicity (17 pts) was: diarrhea 9 pts, neutropenia 9 pts, febrile neutropenia 5 pts, anorexia 5 pts, vomiting 4 pts, fatigue 3 pts, mucositis 1 pt. Chemotherapy dose attenuation was required for diarrhea in 5 pts, for neutropenia in 4 pts, and for folliculitis in 1 pt. One patient was removed from study during week 6 for prolonged diarrhea/ dehydration. Due to the 2-step design of the trial, accrual is on hold pending a 3rd required pathologic CR in the first 17 patients. Conclusions: Compared to other trials of irinotecan, cisplatin, radiation therapy, and surgery in similar groups of esophageal cancer patients, early results for this combination with cetuximab suggest a lower complete response rate and higher overall toxicity. Additional data will be available at ASCO. Supported by Bristol-Myers Squibb. No significant financial relationships to disclose.

Abstract
To develop a potent hypoxia-inducible promoter, we evaluated the usefulness of chimeric combinations of the (Egr-1)-binding site (EBS) from the Egr-1 gene, the metal-response element (MRE) from the metallothionein gene, and the hypoxia-response element (HRE) from the phosphoglycerate kinase 1 gene. In transient transfection assays, combining three copies of HRE (3 x HRE) with either EBS or MRE significantly increased hypoxia responsiveness. When a three-enhancer combination was tested, the EBS-MRE-3 x HRE (E-M-H) gave a hypoxia induction ratio of 69. The expression induced from E-M-H-pGL3 was 2.4-fold higher than that induced from H-pGL3 and even surpassed the expression from a human cytomegalovirus promoter-driven vector. The high inducibility of E-M-H was confirmed by validation studies in different cells and by expressing other cDNAs. Gel shift assays together with functional overexpression studies suggested that increased levels of hypoxia-inducible factor 1alpha, metal transcription factor-1 and Egr-1 may be associated with the high inducibility of the E-M-H chimeric promoter. E-M-H was also induced by hypoxia mimetics such as Co2+ and deferoxamine (DFX) and by hydrogen peroxide. Gene expression from the E-M-H was reversible as shown by the reduced expression of the transgene upon removal of inducers such as hypoxia and DFX. In vivo evaluation of the E-M-H in ischemic muscle revealed that erythropoietin secretion and luciferase and LacZ expression were significantly higher in the E-M-H group than in a control or H group. With its high induction capacity and versatile means of modulation, this novel chimeric promoter should find wide application in the treatment of ischemic diseases and cancer.

Abstract
We have designed the gene delivery carrier targeted to Molt 4 cells, human leukemia T cells, using monoclonal antibody against leukemia-specific JL1 antigen, anti-JL1 antibody, as a targeting moiety. Anti-JL1 antibody has been proven to bind to JL1 antigen and subsequently be internalized into Molt 4 cells, demonstrating that anti-JL1 antibody has the potential as a targeting ligand for leukemia-specific gene transfer. Anti-JL1 antibody was modified with the heterobifunctional crosslinker, PDPH, at carbohydrate sites and conjugated to thiolated poly-L-lysine (PLL) via disulfide bridges. The composition and antigen binding affinity of antibody-PLL conjugates were analyzed by the amino acid analysis and the flow cytometry, respectively. Antibody-PLL conjugates neutralized pSV-beta-galactosidase plasmid DNA at 5:1 weight ratio and condensed into about 200--300-nm complexes. DNA/antibody-PLL complexes were effectively internalized into Molt 4 cells after 4 h incubation at 37 degrees C and showed significantly higher in vitro transfection efficiency than DNA/PLL complexes and DNA/Lipofectin formulation due to the targeting effect of receptor-mediated endocytosis induced by anti-JL1 antibody.
