The aim of this study was to investigate the effects of a 2-week ingestion of grape seed extract(300 mg/day) on cardiovascular response and vascular endothelial cell function at rest and during handgrip exercise in prehypertensive individuals. Nine prehypertensive men, aged 24.6±3.1 yrs, repeatedly participated in both grape seed extract trial and placebo trial in a randomized, double-blind, crossover manner. While the subjects ingested grape seed extract or placebo in a 2-week trial, their cardiovascular response, blood vessel diameter, blood flow volume, and vascular endothelial cell function at rest and during handgrip exercise were measured. Each variable was compared between two trials as well as between two tests simultaneously using a repeated two-way ANOVA. Main result of the present study were as follows: 1) Systolic blood pressure decreased significantly at rest after the 2-week ingestion of grape seed extract. 2) Systolic blood pressure and mean blood pressure decreased significantly during handgrip exercise after the 2-week ingestion of grape seed extract. 3) Flow-mediated dilation volume and % flow-mediated dilation increased significantly after the 2-week ingestion of grape seed extract. It was concluded that 2 weeks of ingestion of grape seed extract would have an positive effect on cardiovascular response and vascular endothelial cell function at rest and during handgrip exercise in prehypertensive men. Future research investigating the effects of various period and amount of ingestion of grape seed extract during aerobic exercise including large muscle group would be warranted.

The superficial spreading type of early gastric cancer has usually been defined as an early gastric cancer in which the product of the longest diameter and the diameter perpendicular to it was greater than 25㎠. Although the superficial spreading type of early gastric cancer is histologically aggressive compared with those without such histological aggressiveness, the 5 year survival rate is as good as a non-superficial spreading types of early gastric cancers if the wide surgical resection with extensive lymph node dissection is performed as a treatment. We experienced a case of superficial spreading early gastric cancer in a 59-year-old man. This case is reported with a brief review of related literature.

Hepatoid carcinoma is a primary extrahepatic carcinoma whose morphology, immunohistochemistry, and behavior are similar to those of hepatocellular carcinoma. The most common sites of extrahepatic carcinoma are the stomach and ovary, but nine cases of hepatocellular differentiation of the pancreas have been reported in the literature. We report another case of hepatoid carcinoma of the pancreas that was associated with the development of a pancreatic endocrine carcinoma in a 46-year-old man. Serum alpha-fetoprotein (AFP) was elevated to 262.49 IU/mL and radiological examinations revealed a mass measuring 7.5 cm in diameter in the head of the pancreas. He underwent a conventional Whipple operation, and light microscopy showed adenocarcinoma that was immunopositive for AFP, hepatocyte antigen, cytokeratin, chromogranin, synaptophysin, and alpha-1 antichymotrypsin. Although hepatoid differentiation was not shown unequivocally histologically, other immunohistochemistry findings supported the diagnosis of hepatoid carcinoma combined with neuroendocrine carcinoma. The patient was healthy and had no evidence of recurrence at 4 months after the surgery. This report describes why hepatoid carcinoma should be considered as a differential diagnosis of a pancreatic mass, especially when serum AFP is elevated. (Gut Liver 2010;4:98-102)

The present study examined the structure and patterns of ethnic identity in a sample of Korean-Chinese parents and their adolescents residing in the Jilin Province in China. The ethnic identity of these participants(total :148 parents:100 adolesents:48) includes two major components : Korean identity and Chinese identity. Each of these components was measured in three different modalities : behavioral, affective and cognitive. The results are summarized as follow ; 1) Generational comparisons between Korean identity scores of parents and adolescents indicated similarities in the modalities of cognitive and behavioral identities. Both groups shared a Korean orientation manifested in their high level of Korean behavior and cognition. However, both groups also shared a relatively high level of Chinese identity. In summary, dual identity appeared to be preserved over time. The parents scored higher than the adolescents in their affective modality of Korean identity. Chinese identity was scored higher in the adolescents than korean identity in their affective modality. The generational comparisons indicated that the adolescents were acculturated in their affect than their parents. 2) Comparison of men and women in the strength of identity' component showed higher cognitive scores among the men. in Korean identity, compared with Chinese identity. Men were more identified with "Chinese" and "Korean" in the affective component of their identity.

The rain water samples were collected at Chunchon and Seoul by using wet only automatic sampler from January 1996 through December 1997. The daily base rain water samples collected over than 95% rainy events during the whole period. The samples were measured both pH and conductivity, and were analysed major ionic components, SO₄^(2-), NO₃^(-), Cl^(-), NH₄^(+), Ca^(2+), Na^(+) and K ^(+), by ion chromatography. In 1996, about 77% sampled rain water showed below pH 5.6 and the 60% of rain water was lower than pH 5.0. The volume weighted average pH was 4.7 at all sites. In 1997, the volume weighted average pH was 4.6 and 4.9 at Seoul and Chunchon, respectively. Among the rain water samples, 87% and 55% of samples showed below than pH 5.6 and 5.0, respectively. The pH value of Chunchon was significantly (p<0.05) lower than Seoul at the rain samples for less than 20 ㎜ rainfall. However conductivity of the rain samples were 20.9 μS/㎝ for 1996 and 27.7 μS/㎝ for 1997 at Seoul, and 19.1 μS/㎝ for 1996 and 14.1 μS/㎝ for 1997 at Chunchon. H₂SO₄AND HNO₃CONTRIBUTED 65.9% and 29.6% of free acidity at Seoul, respectively. The ratio of [NO₃^(-)]/[nss-SO₄^(2-)] were 0.43 at Seoul and 0.51 at Chunchon for rain samples for less than 20 ㎜ rainfall.

It is reported that alcohol drinking by pregnant mothers often leads to abnormal fetal development including fetal alcohol syndrome(FAS) in both humans and experimental animals. The FAS is characterized by prenatal and postnatal growth retardation, distinct craniofacial dysmorphology, and central nervous system dysfunctions such as mental retardation. However, molecular mechanisms for FAS is not completely elucidated as yet. In this study, developmental toxicity of ethanol and its metabolite, acetaldehyde were evaluated using whole embryo culture. In addition genes inducing FAS were investigated by the technique of cDNA microarray. Embryos treated with ethanol showed growth retardation, abnormal tail torsion, open neural tube, open caudal neural tube and abnormal somite at concentrations of 0.1∼0.5%. Also embryos treated with acetaldehyde showed growth retardation including allantois, open caudal neural tube, reduction number of somite and abnormal tail torsion at concertrations of 5×10^(-4)∼2.5×10^(-3)%. RNAs from embryos of control and ethanol treatment were reverse transcribed into cDNA tagged with Cy3 or Cy5 and hybridized with cDNA probe of rat in 'toxicology chip'. Ethanol 0.5% treatment resulted in alteration in expression of several genes including 'serum deprivation response', 'Cide-b' and 'check point suppressor 1'. Northern blot analysis is conducted for identification of genes related to FAS.
