  • We examined three nature restoration projects in urban areas of Japan, China, and Korea. A prefectural park(29ha) has been under construction since 2005 on an abandoned industrial site in the southern part of Amagasaki City, Hyogo Prefecture, central Japan. Shanghai Central Park(28ha) was redeveloped in 2002 on a site that was formerly the old downtown in central Shanghai. Seoul Forest Park was developed as a large urban park(116ba) in 2005 in Seoul. All three parks were developed as urban parks by local governments. Citizen involvement is common to all three examples. One of main purposes of the Hyogo prefectural park and the Seoul Forest Park was the reuse of unused or abandoned areas. One goal in Hyogo, Shanghai, and Seoul was to restore the urban ecosystem and preserve the environment. We discussed the meaning of nature restoration in urban areas.

  • Pharmacogenomics research requires an intelligent integration of large-scale genomic and clinical data with public and private knowledge resources. We developed a web-based knowledge base for KPRN (Korea Pharmacogenomics Research Network, http://kprn.snubi. org/). Four major types of information is integrated; genetic variation, drug information, disease information, and literature annotation. Eighteen Korean pharmacogenomics research groups in collaboration have submitted 859 genotype data sets for 91 disease-related genes. Integrative analysis and visualization of the large collection of data supported by integrated biomedical path­ways and ontology resources are provided with a user-friendly interface and visualization engine empowered by Generic Genome Browser.

  • Cerebral toxoplasmosis is often life-threatening in an immunocompromised patient due to delayed diagnosis and treatment. Several differential diagnoses could be possible only with preoperative brain images of cerebral toxoplasmosis which show multiple rim-enhancing lesions. Due to the rarity of cerebral toxoplasmosis cases in Korea, the diagnosis and treatment are often delayed. This paper concerns a male patient whose cerebral toxoplasmosis was activated 21 years post kidney transplantation. Brain open biopsy was decided to make an exact diagnosis. Cerebral toxoplasmosis was confirmed by immunohistochemistry and PCR analyses of the tissue samples. Although cerebral toxoplasmosis was under control with medication, the patient did not recover clinically and died due to sepsis and recurrent gastrointestinal bleeding.

  • A case of renal candidiasis is reported in a 4-year-old male Masked Palm civet (Paguma larvata) On necropsy, the kidneys were bilaterally swollen, pale and had numerous 1 to 3 mm diameter white foci throughout the parenchyma on cut section. The urinary bladder was filled with opaque and milky exudate. Histologically, severe infiltration of neutrophils and macrophages and necrosis were noted in the interstitial areas of both cortex and medulla and in the lumens of renal tubules and collecting duct often resulting in cystic dilation of the tubules. PAS-positive fungal yeasts or pseudohyphae were often associated with the lesion. Candida albicans was isolated from the kidney and urinary bladder.

  • In this study, we evaluated the cytoprotective effects of antioxidative substances in hydrogen peroxide ($H_{2}O_{2}$) treated Mel-Ab melanocytes. Tested substances include selenium, quercetin, green tea (GT) extract, and several vitamins (ascorbic acid, Trolox, and folic acid). Of these, both quercetin and GT extract were found to have strong cytoprotective effects on $H_{2}O_{2}$­induced cell death. We also examined additive effects, but no combination of two of any of the above substances was found to act synergistically against oxidative damage in Mel-Ab cells. Nevertheless, a multi-combination of GT extract, quercetin, and folic acid appeared to prevent cellular damage in a synergistic manner, which suggests that combinations of antioxidants may be of importance, and that co-treatment with antioxidants offers a possible means of treating vitiligo, which is known to be related to melanocyte oxidative stress.
