Background: The end-tidal carbon dioxide tension(ETCO₂) is defined as a partial pressure of carbon dioxide at the end of an exhaled breath. The purpose of this study is to determine the correlation between ETCO₂and arterial carbon dioxide tension(PaO₂) in nonintubated patients with respiratory distress in emergency department(ED). Methods: A prospective non-blind study was performed in ED of our university hospitals. Participants included all nonintubated adult patients with respiratory distress requiring arterial blood gas analysis. ETCO₂was measured with a capnography monitor during tidal volume breathing. ETCO₂were recoreded at the time of arterial blood gas sampling. The correlation between ETCO₂and PaCO₂was analyzed in all patients and in subgroups by simple linear regression. Results: Sixty patients were enrolled. In all patients, ETCO₂was 5.72mmHg lower than PaCO₂and correlated well with PaCO₂(r²=0.716). ETCO₂correlated best with PaCO₂in patients who were either acidotic or non-smoking. Conclusion: ETCO₂correlate well with PaCO₂in nonintubated patients with respiratory distress in ED. ETCO₂may be sufficient to reflect PaCO₂in selected patients and obviate the need for repeat arterial blood gas determination.

증자시 높은 점성이 문제되는 쌀보리를 기질로 알콜발효를 행할 경우, 기질의 점성문제를 해결하여 발효조건을 개선하면서 생산수율을 올릴 수 있는 상업용 액화효소를 검토하였다. 쌀보리 증자액화시 BAN을 사용한 경우 기절의 점도는 T120L의 1/3 정도로 떨어졌으며 최종 알콜수율도 T120L에 비해 원료 Ton 당 4 ℓ 정도 더 높게 나왔다. 알콜의 수율은 사용한 당화효소의 종류에 의해서도 영향을 받았다. 산업 규모에서 BAN을 사용한 쌀보리의저온증자가 가능하였으며 고온증자에 비해 알콜수율도 388.4에서 390.4 ℓ/Ton으로 약간 증가하였다. 또 이때 사용한 기질의 전분가를 분석하였는데, 산가수분해 및 효소가수분해법에 의한 쌀의 전분가 분석치는 큰 차이를 보이지 않았으나 쌀 보리의 경우는 효소가수분해법에 의한 값이 산가수분해법에 비해 10% 정도 낮게 나타났다. 이때 BAN은 T120L에 비해 전분가가 약 1% 높게 나왔다. Various treatments of naked barley with commercial liquefying enzymes have been employed to reduce high viscosity of naked barley in cooking as a raw material for alcohol production and to increase alcohol yield. The enzyme BAN used for cooking and liquefaction of naked barley was able to make a reduction of one third of viscosity and to enhance alcohol yield of 4 l/Ton of raw material than the T120L was. Of course, alcohol yield depended in part on the applied saccharifying enzymes. The low temperature cooking of naked barley with BAN was favorable compared with high temperature cooking of both of reducing viscosity (210 vs. 237 cp) and final alcohol yield (Yp/so; 0.397 vs. 0.395 g/g) in industrial scale.

The effects of chronic chitosan salt supplementation on the systolic (SBP) and diastolic blood pressure (DBP), and physiological parameters were investigated in healthy male and female adult. Chitosan salt was conducted by measuring various health-related factors such as body composition, plasma $Na^+$, $Cl^-$, lipid, and lipoproteins profiles, glutamic oxaloacetic transaminase (GOT), and glutamic pyruvic transaminase (GPT) activity. Chitosan salt supplementation no significant differences before and after supplement in body composition variables and in SBP and DBP in either male or female. Plasma sodium and chlorine concentration no significant changes during chitosan salt supplementation, and no significant difference between two genders. Plasma GOT and GPT activity no different before and after supplement in either male or female. GOT activity significantly higher for male before supplement (p<0.05), and 2 weeks after supplement (p<0.01). The lipid and lipoproteins profiles of plasma no significant changes during chitosan salt supplementation in either male or female subjects. In summary, the chronic intake of chitosan salt did not affect the SBP or DBP, and posed no health risks.

Since 1998, a new viral disease with high mortality has been consistently recorded in Korea in cultured carp, Cyprinus carpio. In this study, we investigated an epizootic of the disease that caused high mortality rates in carp obtained from 11 farms in Korea between 1999 and 2007. Assessment of koi herpesvirus (KHV) levels in diseased carp was carried out to determine if this virus was the etiologic agent of disease in this instance. High mortality rates in carp were recorded mainly in the spring and autumn at water temperatures between $19^{\circ}C$ and $24^{\circ}C$. Diseased fish typically showed surface discoloration, with a thick opaque mucus covering the body and gills. Protozoan parasites and bacteria were recovered from 7/29 (24%) and 2/26 (8%) of fish, respectively. Evidence of viral infection was marked; cytopathic effects (CPEs), characterized by cell rounding and an extended cytoplasm in fathead minnow (FHM) cells, were detected in 40/41 fish (98%). A high mortality rate (80%) resulted when supernatants of cell cultures showing CPEs were applied to previously healthy fish. KHV was detected by polymerase chain reaction in 6/41 fish (15%), but was not detected in supernatants obtained from cell cultures showing CPEs. These results suggest that KHV may not be the etiologic agent of the high mortality occurring among cultured carp in Korea; therefore, some other-as yet unidentified-infective agent must be responsible.

Viral haemorrhagic septicaemia virus (VHSV) is an epidemic virus in olive flounder Paralichthys olivaceus farms in Korea, since the virus have first isolated in 2001. In the present study, partial glycoprotein (G) gene nucleotide sequences of seven Korean VHSV from cultured olive flounder and wild marine fishes in coastal areas of Korea were analyzed to evaluate their genetic relatedness to worldwide isolates. Phylogenetically, all Korean VHSV formed only one minor cluster including Japanese isolates, in genotype IVa, while the North America isolates formed a different minor cluster in genotype IVa. These results suggest that Korean VHSV could be an indigenous virus in Korean and Japanese coastal areas, but have not been introduced from North America.
