  • L-[18F]FMAU ([18F]1b) was prepared from the precursor 2-O-[(trifluoromethyl)-sulfonyl]-1,3,5-tri-Obenzoyl- α-L-ribofuranose, by coupling the radioactive fluoro-sugar with the corresponding silylated thymine in 4 steps. The final products, including the α and β anomers, were purified using reverse phase HPLC with an appropriate solvent (5% CH3CN/H2O) at a flow rate of 3.0 mL/min. The total elapsed time of synthesis was about 180-200 min from EOB. The α/β anomeric ratio of the compounds was about 1:9, and the radiochemical purity of the product (β-form) was >98% with decay-corrected yields of 25-35%. All radioactive samples were confirmed using co-injection with pure non-radioactive analogues in every step. In the cellular uptake in vitro test of herpes simplex virus-thymidine kinase (HSV1-TK) gene expressed cells, the percent uptake of injected dose (%ID) of L- and D-FMAU was 37.28 and 65.86, respectively after 240 min incubation. However, the relative uptake (MCA-TK/MCA cellular uptake ratio) of L-FMAU was higher than that of D-FMAU (%ID of L-FMAU, 0.36 and D-FMAU, 0.93 after 240 min incubation in MCA cells). This means that L-FMAU will show better specific HSV1-TK gene expressed cell uptake for selective HSV1-TK gene imaging.

  • This study was performed to discover the underlining influences of Herpes Simplex virus (HSV) and Varicella Zoster virus (VZV), to detect the changes of whole protein and mucin level and to observe protein profiles in the saliva when recurrent aphthous ulcer (RAU) was present. Unstimulated whole saliva was collected from 23 patients who for over three years had a clinical history of RAU, in a group of 10 women and 13 men, ranging from 11 to 72 years of age, and 20 healthy subjects, in a group of 8 women and 12 men, who did not have the symptoms nor a past history of RAU. Through the means of Polymerization Chain Reaction, genomic DNA from the HSV and VZV was purified from the saliva samples for identifying precisely the two types of viruses, and the level of whole protein and sialic acids in the saliva and the ratio of sialic acid to whole protein were measured, and SDS-polyacrylamide gel electrophoresis was performed. The results obtained were as follows ; 1. 39.13% of patients showed 224 bp bands of VZV DNA, those were appeared more in patients than in control group (p<0.01), but there was no significant difference between patients and control group in HSV DNA (p>0.05). 2. The concentration of whole protein in men patients was lower than in men control group (p<0.05), but there were no significant differences between patients and control in other groups (p>0.05). 3. The concentration of sialic acids from patients was lower than control group in all groups (p<0.05). 4. The concentration of sialic acids in proportion to that of whole protein was lower in patients than in control group (p<0.05), and in the two women groups (p<0.01), but no noticeable difference was found between the two men groups (p>0.05). 5. There were no consistent differences observed in the protein profiles of patients with control group except that certain protein bands near 50 kDa was lower in patients than in control group. These results suggest that viruses such as HSV and VZV and reduction of salivary whole protein and mucin levels are related to development of RAU.

  • In order to anticipate disease pattern and health problems of Koreans in the 1st part of 21st century (by the year 2020), transition of population characteristics, mortality and morbidity data during the last 30 years Koreans have experienced were reviewed. On the actual basis of epidemiologic transition process that has undergone during last 30 years since 1960 along with socioeconomic development and successful implementation of selective national health policies (family planning, medical insurance and etc.), following changes can be expected in the 21st century in Korea, under the assumption that the current rate of progress is maintained. The population of South Korea alone will be doubled the population of 1960 by the year 2013 : aged Population older than 65 years will be increased from 3.3% in 1960 to 11.4% in 2020 with increased average age of the population from 23.6 year in 1970 to 39.2 year in 2020; urban population from 28% in 1960 to 83% in 2005. GNP/capita has increased tremendously from U.S. $120 in 1970 to $6,749 in 1992, and the government estimated it would be 519,350 in 2010 and $29,460 in 2020. Growth and developmental indices of children, educational achievement and social status of women also showed a remarkable improvement and anticipated to make futher progress. Leading causes of mortality and morbidity have shown a striking change during the last 30 years, from infectious diseases to chronic degenerative diseases and man-made injuries. Occurrence of communicable diseases may become minimal although viral hepatitis, venereal diseases Including AIDS, and well adapted herpes virus infections will maintain their endemic level. Newly evolving infectious agents, however, should be carefully monitored because of rapidly changing environments and human behaviours. Tuberculosis may increase up to the epidemic level when AIDS prevails. Ischemic heart diseases may increase steadily with increasing occurrence of hypertension and diabetes mellitus whereas cerebrovascular diseases may be decreased slowly. Musculaskeletal diseases which contribute a lot to the disability of aged people may be a major health problems due to increased aged population. Mental diseases, particularly that caused by alcohol and drug abuse, and senile dementia may become a prominent health problem. On the other hand injuries caused by traffic and industrial accidents that have shown most striking increase till now may be decreased considerably by intensive intervention. The health policies in the 21st century will be oriented to the health promotion for good quality life rather than life-savings.

  • The purpose of this study was to examine the efficacy and mechanism of the cryo-precipitation, solvent/detergent (S/D) treatment, monoclonal anti-FVIIIc antibody (mAb) column chromatography, Q-Sepharose column chromatography, and lyophilization involved in the manufacture of antithemophilic factor VII(GreenMono) from human plasma, in the removal and/or inactivation of blood-borne viruses. A variety of experimental model viruses for human pathogenic viruses, including the bovine viral diarrhoea virus (BVDV), bovine herpes virus (BHV), murine encephalomyocarditis virus (EMCV), and porcine parvovirus (PPV), were all selected for this study. BHV and EMCV were effectively partitioned from a factor VII during the cryo-precipitation with a log reduction factor of 2.83 and 3.24, respectively. S/D treatment using the organic solvent, tri(n-butyl) phosphate (TNBP), and the detergent, Triton X-100, was a robust and effective step in inactivating enveloped viruses. The titers of BHV and BVDV were reduced from the initial titer of 8.85 and $7.89{log_10} {TCID_50}$, respectively, reaching undetectable levels within 1 min of the S/D treatment. The mAb chromatography was the most effective step for removing nonenveloped viruses, EMCV and PPV, with the log reduction factors of 4.86 and 3.72, respectively. Q-Sepharose chromatography showed a significant efficacy for partitioning BHV, BVDV, EMCV, and PPV with the log reduction the log reduction factors of 2.32, 2.49, 2.60, and 1.33 respectively. Lyophilization was an effective step in inactivating g nonenveloped viruses rather than enveloped viruses, where the log reduction factors of BHV, BVDV, DMCV, and PPV were 1.41, 1.79, 4.76, and 2.05, respectively. The cumulative log reduction factors of BHV, BVDV, EMCV, and PPV were ${\geqq}$11.12, ${\geqq}$7.88, 15.46, and 7.10, respectively. These results indicate that the production process for GreenMono has a sufficient virus-reducing capacity to achieve a high margin of the virus safety.

  • Herpetic stromal keratitis (HSK) is an inflammatory disorder induced by HSV-1 infection and characterized by T cell-dependent destruction of corneal tissues. It is not known what triggers $CD4^+$ T cell migration into the stroma of HSV-1-infected corneas. The keratocyte is a fibroblast-like cell that can function as an antigen-presenting cell in the mouse cornea by expressing MHC class II and costimulatory molecules after HSV-1 infection. We hypothesized that chemokines produced by stromal keratocytes are involved in $CD4^+$ T cell infiltration into the cornea. We found that keratocytes produce several cytokines and chemokines, including MCP-1, RANTES, and T cell activation (TCA)-3. HSV-1 infection increased the production of MCP-1 and RANTES by keratocytes, and these acted as chemoattractants for HSV-1-primed $CD4^+$ T cells expressing CCR2 and CCR5.

Expression of MCP-1 in the corneal stroma was confirmed in vivo. Finally, when HSV-1-primed $CD4^+$ T cells were adoptively transferred into wild type and MCP-1-deficient mice that had been sublethally irradiated to minimize chemokine production from immune cells, infiltration of $CD4^+$ T cells was markedly reduced in the MCP-1-deficient mice, suggesting that it is the MCP-1 from HSV-1-infected keratocytes that attracts $CD4^+$ T cells into the cornea.
