  • To examine the effects of Euglena rubra (E. rubra) feeding on Nile tiapia, Oreochromis niloticus were fed diets containing dried powder of E. rubra at 0.5 or 2% for 4 weeks. Growth, selected hematological and non-specific immune parameters were assessed at 2 and 4 weeks. There were no significant changes in body weigh gain and erythrocyte levels. However a significant and diet E. rubra level-related decrease in leukocyte level was noted. Significant increases were observed in respiratory burst activity (nitroblue tetrazolium reduction) and lysozyme activities following E. rubra feeding. These results indicate that E. rubra could be beneficial to fish, but excess feeding could toxic.

  • This research investigates the effect of the Crataegus pinnatifida BGE. var. major N.E. BR(CPVM) on Alzheimer's disease. The CPVM extract suppressed the expression of IL-1 β, IL-6, APP, AChE mRNA in PC-12 cells treated with CT105. The CPVM extract suppressed the AChE activity, and the production of APP significantly in PC-12 cells treated with CT105. The CPVM extract group showed a significant inhibitory effect on the memory deficit for the mice with Alzheimer's disease induced by CT105 in the Morris water maze experiment. The CPVM extract suppressed the over-expression of IL-1 β, TNF- α and ROS in the mice with Alzheimer's disease induced by CT105. This study suggests that CPVM may be effective for the prevention and treatment of Alzheimer's disease.

  • 레이저가 의학영역에서 사용된 후 구강내 연조직과 경조직 병소에 대한 임상적 적용에 관한 관심이 커져왔다. 레이저가 조사되는 부위에서는 대부분 연기가 발생한다. 이 경우 병원체가 존재하는 병소에 대한 레이저치료시 발생되는 연기속에 병원체가 포함되어 이Tekas 환자와 술자는 이의 흡입가능성이 크므로 균혈증 및 상기도나 호흡계의 의원성 감염이 유발될 수 있다. 저자는 레이저치료시 발생되는 연기속에 병원체가 포함되어 있는지의 여부를 규명하기위해 각각 10개의 실험군에 통기성 미생물인 Escherichia coli(E.coli)가 배양된 brain geart infusion (BHI) 배지와 E.coli 가 존재하는 치근단 병소를 실험적으로 만든 후 각각 pulsed Nd:YAG 레이저를 조사해 연기를 채취, 배양, 분석하여 다음과 같은 결과를 얻었다. 1. Pulsed Nd:YAG 레이저를 E. colir 배양된 agar substrate 와 실험적으로 만들어진 치근단부위의 E.coli 현탁액에 조사시 발생된 연기에서 처음 접종된 것과 같은 E.coli가 검출되었다. 2. 감염병소에 pulsed Nd:YAG 레이저를 조사시 발생되는 연기의 유해효과로부터 환자와 술자 및 보조자의 보호를 위해 효과적인 흡입기를 사용이 권장된다.

  • 목 적: 기관지 천식은 기도의 과민 반응을 특정으로 하는 기도 내 염증 질환이다. 최근 염증반응에 관여하는 cyclooxygease(COX) 에 대해 90년대 초 새로운 형태의 COX2가 발견되었다. 또한 최근 COX2만을 선택적으로 억제하는 약제가 개발되어 이에 대한 연구가 활발히 진행 중이다. 따라서 저자는 기도 내 염증 반응을 특징으로 하는 기관지 천식에서 COX2 발현 양상과 혈중 프로스타글란딘 E2를 측정하고 COX2 억제제를 사용한 후 COX2 발현, 프로스타글란딘 E2의 변화 및 기도 저항의 변화를 알아보았다. 대상 및 방법: 총 38마리의 Sprague-Dawley 백서(250-300g)를 대상으로 정상 대조군, 천식 대조군, 치료군의 3군으로 나누어 실험하였다. 각 세 군에 대해 제 28 연구일에 즉시형 기관지 수축 반응을 유발시킨 후 기도 저항을 측정하였다. 제 30연구일에 혈장 내 프로스타글란딘 E2 수치를 측정하고 기도 및 폐 실질 내 호산구 침윤 정도 및 COX2 면역 조직 화학 염색에 대한 발색 정도를 image analysis를 통해 확인하였다. 결 과: 기관지 및 폐 실질 내 호산구 침윤은 천식 대조군과 치료군의 두 군간에 통계적으로 유의한 차이가 없었다. COX2 면역 조직 화학 염색 및 혈중 프로스타글란딘 E2 농도에 있어서 정상 대조군, 천식 대조군, 치료군의 세 군에서 통계적으로 유의한 차이가 없었다. 치료군에서 nemesulide 투여 후 OVA으로 즉시형 기관지 수축 반응을 일으킨 상태에서 측정한 기도 저항은 nemesulid를 투여하기 전과 비교해서 통계적으로 유의한 차이가 없었다. 결 론: 결론적으로 COX2는 알레르겐 유발성 천식의 병태 생리에 있어서 주된 경로가 아니며 향후 천식 모델에서 COX2 억제제를 사용한 후 lipoxygenase 의한 대사산물과의 상관 관계와 COX2 억제제의 투여하는 방법에 있어서 투여 용량 또는 투여 횟수를 달리하거나 COX2에 대한 선택성이 더 높은 약제를 투여한 후 기도 내 COX2의 변화에 대한 연구가 필요하리라 사료된다.

  • The recombinant lysozyme-HJL34 proteins were expressed and purified using commercial Escherichia (E.) coli expression system. Stx2e+ F18+ E. coli, Actinobacillus pleuropneumoniae (APP), Streptococcus (S.) suis, and Clostridium (C.) perfringens strains were isolated from pigs. The minimum inhibitory concentrations (MICs) of the recombinant lysozyme-HJP34 proteins were examined by means of the microtiter plate method, according to the NCCLS recommendations. The possibility of its as the alternatives to antibiotics was tested in piglets. The MICs were determined as 75 ㎍/mL, 300 ㎍/mL, 75 ㎍/mL, 35.5 ㎍/m against Stx2e+ F18+ E. coli, APP, S. suis, C. perfringens, respectively. A total of 25 piglets were divied 5 groups. The piglets in group A~C were fed with commercial feed and those in groups D, E were fed with commercial feedstuff. All piglets in groups B~E were challenged with virulent Stx2e+ F18+ E. coli, APP, S. suis strains. Groups C and D were treated with antimicrobial from 24 h after challenge. All piglets in group B died within 3 days after challenge. Among 5 piglets in groups C and D piglets, 80% survived after challenge. Among group E piglets, 60% were alive until the end of this study. Therefore, this study indicates that recombinant lysozyme-HJP34 proteins is a suitable possibility as a feed additive for reduction of diseases by bacterial pathogens in piglet feed.

  • 이 연구는 갑상샘 유두암 환자에서 VEGF, HIF-$1{\alpha}$, E-cadherin, p53의 발현 정도와 병기와의 상관관계를 알아보고자 하였다. 2000년부터 2007년까지 갑상샘 절제술을 시행받은 101명의 환자의 의무기록을 후향적으로 검토하였다. VEGF, HIF-$1{\alpha}$, E-cadherin, p53의 발현은 면역학적으로 조사되었다. 갑상샘 유두암으로 진단된 45세 이상의 환자 중 54명을 대상으로 하여 VEGF, HIF-$1{\alpha}$, E-cadherin, p53의 발현이 분석되었다. E-cadherin의 발현소실과 병기 사이에는 유의한 상관관계가 있었다. VEGF의 발현과 HIF-$1{\alpha}$의 과발현 사이에는 유의한 관련성이 관찰되었다(p<0.05). E-cadherin의 발현소실은 통계적인 유의성은 없었다. HIF-$1{\alpha}$의 높은 발현이 HIF-VEGF 경로를 통해 종양간 맥관형성과 관련된 것으로 여겨진다.

  • Objectives:Although polymorphisms of apolipoprotein E have been investigated in many neuropsychiatric disorders, results were controversial and even contradictory. The purpose of this study was to investigate the genotypes of apolipoprotein E in schizophrenia and healthy controls, and to compare them in two groups in terms of distribution of apolipoprotein E genotype and allele. Method:Using polymerase chain reaction and amplified refractory mutation system, apolipoprotein E genotypes were identified in 77 schizophrenics and 115 healthy control persons. Results:The results were as follows 1) When genotypes of apolipoprotein E were classified into ${\varepsilon}2/2$, ${\varepsilon}2/3$, ${\varepsilon}2/4$, ${\varepsilon}3/3$, ${\varepsilon}3/4$, ${\varepsilon}4/4$ according to phenotypes, there were no statistical differences in genotypes between two groups 2) In terms of allele frequency, there were also no statistical differences between two groups Conclusion:These results suggest that genotypes and alleles of apolipoprotein E seem to be unrelated to the pathogenesis of schizophrenia.

  • We have evaluated the effect of long term treatment of Enicostemma littorale (E. littorale) in type 2 diabetic patients taking pills of aqueous extract of E. littorale regularly as a complimentary medicine for at least 9 months. The effects of E. littorale on glycemic control, lipid profile, cardiac function and DNA damage in these patients were compared with those who had not been regular in taking E. littorale but regular in taking other conventional anti-diabetics. Our data suggest that, E. littorale can maintain normal blood glucose, serum insulin, serum triglycerides levels of type 2 diabetic patients if taken regularly. E. littorale also improves insulin sensitivity, and normalize disturbed lipogram and elevated creatinine levels, thereby produces beneficial effect in preventing cardiovascular complications and may preserve the kidney function. The finding that E. littorale also prevents DNA damage suggest a long term effect in diabetic patients. E. littorale thus can be considered as safe supplementary therapy for a long term and effective management of type 2 diabetic patients.

  • Background: Ginkgo biloba extract is used in disorser of cerebral and peripheral blood circulation, dysfunction of brain, atherosclerosis etc., but there are little study about GbE in oriental medicine. We wished to assessthe efficacy of GbE for the treatment of cerebral infarction Method : The study group comprised 40 patients who arrived at hospital during 48 hours after attack. All patient were devided into two group. The control group was treated with Uhuangcheongsimhuan, Seonghyangjeonggisan, acupuncture therapy only, while the GbE group was treated with above therapy plus 5 days of administration of GbE(40mg three times per day). Result: 1. Symptom improve scores did not showed significant difference between control and GbE group. 2. Vasoreactivity of carotid siphon increased significantly in GbE group after treatment (in the left only : p<0.05). 3. Vasorcactivity of radial artery increased significantly in GbE group after treatment(in the right only ; p<0.05). 4. PT, a-PTT, Fibrinogen did not showed significant changes between before and after treatment in both group. Conclusion: These findings suggest that vasoreactivity increasing effect of GbE may be useful in the prevention and treatment of cerebral infarction. But the vasoreactivity increasing effect of GbE may be different from symptom imroving.
