박인경,김미경,김순동 동아시아식생활학회 2000 동아시아식생활학회지 Vol.10 No.3

This study was conducted to investigate the effect of homogenized kimchi product (HKP) on dough characteristics and quality of bread. Fermented homogenized Chinese cabbage kimchi product was added 0, 10, 20 and 30% to wheat flour. The pH of dough decreased with an increase in the amounts of HKP. which showed at pH 4.9 for the dough added 30% HKP, Fermentation time of the dough was reduced as much as 9~23 minutes as compared with the control products. Loaf volume index of the bread prepared by adding 10-30% HKP increased also by 12,7~19.0%. Hardness, cohesiveness, springiness and gumminess of the bread added with 30% HKP were lower than those of the control. The gas forming cell of the bread added with 30% HKP were good and regular. Crust and internal color of the bread with more HKP had tendency to redness. Sensory quality of the kimchi-bread estimated by shape, flavor and overall quality was better than that of control product, especially the kimchi-bread quality at addition of 30% HKP was best.

Emphysematous cystitis is an uncommon disease in which bacterias produce gas within the bladder wall and surrounding tissue. Patients with diabetes, neurogenic bladder and chronic urinary tract infection are predisposed to the disease. It is usually caused by E.coli and Klebsiella. Severity of illness ranges from an asymtomatic condition to life threatening cystitis. Succesful management depends on early diagnosis with correction of underlying causes, administration of appropriate antibiotics, establishment of adequate bladder drainage and surgical excision of involved tissue when required. We report a case of 52-year-old woman who did not compain of symtoms of cystitis but epigastric pain, nausea, and vomitting. Emphysematous cystitis was revealed on the abdominal X-ray series incidentally. CT scans of the pelvis showed mottled gas bubble within the bladder. After treatment, the symtoms subsided and plain abdominal film showed no evidence of gas shadow in the pelvic cavity.

박성태,황정동,김상열,문헌팔,양세준,김순철,유남진 한국국제농업개발학회 2003 韓國國際農業開發學會誌 Vol.15 No.3

벼 기계이앙 육묘에 주로 사용하고 있는 플라스틱 육묘상자의 문제점을 개선하고 친환경 농업 실현에도 기여할 수 있는 벼 기계이양 종이 육묘상자개발 및 육묘시험 결과를 요약하면 다음과 같다. 1. 폐지 등 혼합물을 고열압착한 종이 육묘상자는 내부 길이가 가로 58㎝, 세로 28㎝, 높이는 2㎝이고 무게는 250g이다. 2. 종이 육묘상자 모의 파종 후 10일~30일 묘소질은 플라스틱 육묘상자 모에 비하여 초장이 1.1~1.8㎝ 짧고 본당 건물중은 0.3~3.7㎎이 떨어졌으나 엽수와 모 충실도는 비슷하였다. 3. 종이 육묘상자 모의 파종 후 30일(중묘) 이앙 시 결주율은 3.3%로 플라스틱 육묘상자 모 결주율 3.2%와 거의 같았고, 출수기, 벼 생육특성 및 수량도 플라스틱 육묘상자와 비슷하였다. 4. 종이 육묘상자의 이점은 플라스틱 육묘상자에 비하여 육묘상자 비용이 약 20% 절감되고 파종 후 운반, 치상 등 작업이 용이하며, 이앙 후 회수, 세척 및 보관관리 노력이 생략된다. 그리고 이앙 후는 논에서 유기물화되므로 친환경농업에도 부합된다. A light and bio-degradable paper tray for seedling raising in machine transplanting rice was developed for the first time and a possibility for rice seedling growth was evaluated. The paper tray was made of mixture of recycling paper and sawdust, and molded under high temperature and pressure. The tray was 58㎝ length x28㎝ width x2㎝ height in size and 250g in weight per tray. The seedling height and dry weight per plant grown at the paper tray were generally 1.1 to 1.8㎝ shorter and 0.3 to 3.7㎎ lighter than those grown at the conventional plastic tray, respectively. However, other characters such as leaf number, seedling health score, missing hill, heading date, panicle and spiketlet number, and milled rice yield were similar to those in the plastic tray. Based on the result of research, the paper tray had following advantages in comparison of the plastic tray. The paper tray could be reduced seedling raising cost by 20% as compared with the plastic tray. Since the paper tray was of lightness even after seedbed soil fill-up, it was more handy and convenient to carry over. Labor input for collecting, washing, and storing the empty tray after seedling transplanting was not needed as the plastic tray. The paper tray was also bio-degraded and transformed into an organic matter, once it was incorporated into soil, which was considered as an environmentally- safe cultivation technology.

박상원,김동우,박주원,이순일,신영학,김의종,오명돈,최강원 대한감염학회 2005 감염과 화학요법 Vol.37 No.2

삼일열 말라리아는 국내에서 재유행하고 있는 감염질환으로, 일반적으로 양성의 임상경과를 거친다. 저자들은 특이한 질병력이 없이 건강하였던 젊은 성인이 국내에서 삼일열 말라리아에 걸린 후 다기관기능부전과 폐출혈으로 사망한 증례를 경험하였다. 환자의 중증 임상경과를 설명할 만한 특이한 인자가 발견되지 않았다. Vivax malaria is a re-emerging infectious disease in Korea with cumulating 19,416 cases as of December 2003 since 1993. Vivax malaria is generally a benign disease with few severe complications. Even in the worldwide literature, there are only small number of case reports on severe complications. We experienced a fatal vivax malaria in a previously healthy young adult with severe multi-organ failure and fatal massive pulmonary hemorrhage. The patient presented with abdominal pain and shock. There were splenic hemorrhage, disseminated intravascular coagulation, oliguric acute renal failure requiring dialysis, and pulmonary hemorrhage leading the patient finally to death. The initial parasitemia was 2,046/μL. Thin smear and PCR revealed only Plasmodium Vivax. There was no explainable cause of death except for the only serological suggestion of Mycoplasma pneumoniae infection without correlating clinical evidence. This is a first case of fatal vivax malaria in Korea since its re-emergence in 1993. Further case monitoring is needed to define whether this is a index case or an isolated one.

Detergent가 NAD의존성 α-glycerophosphate 탈수소효소에 미치는 영향

박수언,이동욱,이희성 중앙대학교 의과대학 의과학연구소 1984 中央醫大誌 Vol.9 No.3

The physical properties and the effects of detergent on the activities of purified NAD-linked a-glycerophosphate dehydrogenase(EC 1.1.1.8, GPDH) from kidney, liver and skeletal muscle of the rat were studied. The activity of this enzyme was measured by the method of White and Kaplan. The enzyme activity of liver (9.65 units/g tissue) was higher than those of other organs, but the highest value of the specific activity was shown in skeletal muscle as 0.058 unit/㎎ protein. These enzymes were purified approximately 167, 286 and 216-fold from kidney, liver and skeletal muscle, respectively, by ammonium sulfate saturation and blue dextran Sepharose column chromatography. These enzymes were composed of two isozymes which have different isoelectric points. Isoelectric points of the two isozymes were 6.5 and 6.7, and the molecular weights were 62,000 and 60,000 daltons. The UV spectrums of the purified enzymes from three organs of the rat showed very simillar pattern. But the representative compounds from three classes of detergents showed different effects on these enzymes. The enzyme of the skeletal muscle was activated by all of the detergents which were studied expect for Triton X-100, whereas the enzymes of the kidney and the liver were not activated or strongly inhibited by all of the detergents. In conclusion, the purified a-glycerophosphate dehydrogenases from the three organs of the rat were the homogeneous proteins out of consideration for physical properties. But the differences in the interaction between enzymes and detergents revealed that there are unsimilarities in the three dimentional structure between the skeletal muscle and those of other two organs inspite of similarities between the enzyme of kidney and that of liver.
