Obesity may cause metabolic syndrome and adult diseases. This study was undertaken to investigate the ameliorative or useful effects of beanleaves on inflammation and liver damage in obese rat models. Rats were divided into three groups: a control group (normal diet, n=6), a fat diet group (45%?fat diet, n=7), and a bean leaf group (45%?fat+Korean bean leaves diet, n=7). Body weights in the bean leaf group were lower than those of the fat group (P<0.05). Serum tumor necrosis factor?α (TNF?α) and prostaglandin E₂ (PGE₂) concentrations were lower in both the control and bean leaf groups than in the fat group (P<0.001). TNF?α concentrations in the bean leaf group were slightly higher than in the control group but statistically significant (P<0.05). The bean leaf group histologically exhibited lower fatty degeneration, spotty necrosis, and leukocyte infiltrations in hepatic tissues than those of the fat group. In the homogenized liver tissues, the cyclooxygenase?2 (COX?2) gene was only expressed in the fat group. The gene expression levels of hepatic TNF?α, inducible nitric?oxide synthase, peroxiome proliferator?activated receptor?α (PPAR?α), poly (ADP?ribose) polymerase (PARP), and transforming growth factor?β1 (TGF?β1) were weaker in the bean leaf group than in the fat group. These results suggest that adding bean?leaves to the diet may ameliorate obesity?induced systemic inflammation and liver damage and that bean leaves may be a useful food for preventing obesity and thereby metabolic syndrome and adult diseases

한국 주변 연안 15개 정점의 퇴적물(0∼20 cm)에서 ^137Cs, ^90Sr, ^239+240Pu 의 농도와 농도비를 조사했다. ^137Cs, ^90Sr, ^238Pu 및^239+240Pu의 평균 방사능 농도는 각각 2.24±0.79 Bq·kg^-1-dry, 0.20±0.04 Bq·kg^-1-dry, 0.009±0.005 Bq·kg^-1-dry 및 0.27±0.17 Bq·kg^-1-dry이다. ^137Cs/^90Sr, ^239+240Pu/^137Cs 및 ^238Pu/229+240Pu의 평균 농도 비와 ^239Pu/240의 평균 원자 비는 각각 11.2±2.9, 0.123±0.053, 0.033±0.01 및 0.218±0.036이다. 퇴적물에서 핵종의 농도 범위와 핵종간의 농도 비는 그 동안 주변국가의 퇴적물에서 조사한 값과 비슷하였다. 퇴적물에서 ^137Cs과 ^239+240Pu의 상관계수는 0.80이다. ^137Cs과 SOM, ^239+240Pu과 점토 함량과의 상관계수는 각각 0.69, 0.67 이다.

The correlation coefficient of ^137Cs and ^239+240Pu is 0.80. The correlation coefficient of ^137Cs and soil organic matter(SOM), and ^239+240Pu and clay content are 0.69 and 0.67, respectively.

변형된 MESI를 이용한 캐쉬 일관성 프로토콜

최인석,조병호,심원 서울産業大學校 産業大學院 1997 大學院論文集 Vol.5 No.-

This paper suggests a cache coherence protocol which improves the efficiency of MESI protocol. The suggested cache coherence protocol maintains 6 types of cache states and ID area. The cache states are divided into 3 valid (exclusive, modified, modified-shared, shared) and 2 invalid (invalid, invalid-by-other) states. ID area holds the identification of the processor module with valid block. We can decrease broadcasting and snooping by the suggested protocol. In addition to it, we can shorten the responce time through cache-to-cache communication. According to simulation results, We get around 2% efficiency improvement compared with MMESSII protocol which is a improved MESI protocol as the number of processors are increasing.

To determine the factors affecting development and recovery of symptomatic vasospasm. the author analysed the results of patients with ruptured intracranial aneurysms treated by nimodipine and prophylactic “triple0H” therapy. From January 1991 to December 1995. 199 patients underwent surgery for ruptured intracerebral aneurysms. Combined hypervolemic hemodilution was initiated at the time of admission. Induced hypertension was added immediately after surgery(aneurysmal neck clipping). All patients received nimodipine intravenously or orally until the 14th day of SAH Sixty patients underwent surgery on Day 0 through 2 after attacks of subarachnoid hemorrhage(Goup A) 105 patients on Day 3 through 14(Group B). and 35 patients after Day 14(Group C). Of 199 patients. 76(38%) patients suffered from symtomatic vasospasm. Symptomatic vasospasm occured in 34% of Group A patients. 33% of Group B patients. and 5% of Group C patients. Symtomatic vasospasm occured more frequently in the older age group. the Fisher group 3 and Hunt & Hess grades 3, 4 and 5 groups. Of 76 patients who suffered from symptomatic vasospasm. 47(62%) patients recovered completely. The author analysed the relationship between recovery rate and sex, age. Hunt & Hess agrde and Fisher group among these 76 patients. Recovery rates between these groups were not significantly different. Based on this experience the author believes that Hunt-Hess grade. Fisher group and age are important factors affecting symptomatic vasospasm development.

Wound healing in the skin may be complicated by both microbial invasion and inflammation. Following injury, platelet degranulation releases a number of chemotactic factors including transforming growth factor (TGF-fl) and platelet derived growth factor (PDGF). TGF-19 is a cytokines that modulates many cellular function and gene expression. However, it is not known whether TGF-P could regulate inducible nitric oxide synthase (iNOS) gene expression during wound healing. Here we report that down regulation of TGF-Q gene expression by antisense oligodeoxynucleotides increase iNOS during wound healing. Our reverse transcription- polymerase chain reaction (RT-PCR) result has shown that antisense TGF-fil oligodeoxynucleotides (ODN) targeting the TGF-J11 translation initiation region markedly reduced TGF-(il mRNA levels in wounded skin. Also, marked reduction in TGF-fl1 mRNA after antisense treatment invited that the increment of iNOS mRNA in wounded skin. Therefore, our irnmunohistochemical studies revealed a "pattern of iNOS product in wounded skin treated antisense TGF-fl1 ODN that was similar to the pattern of RNA synthesis detected by RT-PCR. In conclusion, our results indicated that the regulatory actions of TGF fl1 on iNOS. might be involved in the initiation and faciliates the resolution of inflammation following wounding.

부적절하게 수복된 stainless steel crown에 의해 야기된 하악 제1대구치 이소맹출 치험례

박주석,손흥규,최병재 大韓小兒齒科學會 2000 大韓小兒齒科學會誌 Vol.27 No.1

이소맹출이란 영구치열의 발육 과정 중에 국소적 맹출장애로 인하여 정상적 위치에서 벗어난 치아의 맹출을 말한다. 일반적으로 이소맹출은 2∼6% 정도의 이환율을 보이고, 제1대구치에서 호발하며 주로 상악에서 많이 나타나고 하악에서는 드물다. 이소맹출의 원인은 국소적 원인으로 부적절한 치열궁 길이. 상악 후방부의 성장 부족, 제1대구치의 근심 맹출, 비정상적으로 큰 제1대구치 등이 있고, 유전적인 원인으로 나타날 수도 있으며, 부적절하게 형성된 stainless steel crown에 의해서도 유발될 수 있다. 이소맹출된 치아 중 66%는 가역성이므로 3∼6개월 정도의 관찰 기간이 요구된다고 하였으며, 비가역성 이소맹출인 경우에는 brass wire 나 elastic separator를 이용한 비교적 간단한 치료 방법, 제2유구치의 distal discing, Humphrey appliance 등과 같이 제2유규치를 유지하면서 치료하는 방법 및 제2유구치 발거 후 가철식 장치나 cervical traction headgear를 이용하는 방법 등이 소개되고 있다. 본 증례는 연세대하교 치과대학병원 소아치과에 내원한 7세된 남환아로 구강 검사 및 방사선 검사 결과, 4년전 개인 치과의원에서 수복된 우측 하악 제2유구의 stainless steel crown을 제거하고, Humphrey appliance를 제작하여 장착하였으며, 약 10주 후에 고착 상태가 해소되었다. 본 증례에서와 같이 이소맹출은 부적절하게 형성된 stainless steel crown에 의해 일어날 수 있으므로, stainless steel crown의 수복 치료에 있어서, 적절한 크기의 선택, trimming 및 contouring 등이 매우 중요하다. Ectopic eruption is out of a normal position by local eruption disturbance in the developing permanent molar. The prevalence of ectopic eruption is reported to be the between 2 and 6%, most often associated maxillary first permanent molar, whereas, the occurrence for the mandibular is quite rare. The etiologic factors of ectopic eruption are inadequate arch length, lack of growth in the posterior region of the jaw, mesially inclined eruption path of first permanent molars, abnormally large first permanent molars, hereditary factor and a stainless steel crown which has been improperly restored. Ectopic eruption can be treated by the use of brass wire, separating elastics, distal disking and Humphrey appliance and the use of removable appliance and cervical traction headgear after extraction of the second primary molar. This case was that lower right first permanent molar was mesially tilted state by locking on the stainless steel crown of a lower right second primary molar. The stainless steel crown was removed and Humphrey appliance was set. Like this case, ectopic eruption could be happened by the stainless steel crown which improperly restored. In restoration of the stainless steel crown, selection of proper size, trimming and contouring are very important.
