신규만,조도상,조용재,김명현,김상진,김성학 이화여자대학교 의과대학 2005 EMJ (Ewha medical journal) Vol.28 No.1

Objectives : Of all the chronic pain syndromes postherpetic neuralgia ranks the most refractory to treatment. The eight postherpetic neuralgia patients have been treated with nerve blocks or neurolysis and obtained good result. We evaluate the therapeutic effect of nerve blocks for postherpetic neuralgia and reviewed the pathology, clinical consideration, treatments and prevention. Materials and Methods : Eight patients with established postherpetic neuralgia enrolled in pain clinic of Mokdong Hospital of Ewha Womans University from March,2004 to December. Average age at 58 and about 63% of patients were over 68 years. Affected area of forehead was two patients. They have been treated with stellate ganglion block (SCB), two times supraorbital and supratrochlear nerves blocks and neurolysis with absolute alcohol. Face affected patient has was one and has been treated with 5 times SGB, 2 times supraorbital and supratrochlear nerves blocks, infraorbital and mental nerves blocks, and then 2times maxillary and mandibular nerves blocks. Chest affected two patients were treated with intercostal nerve blocks. Thoracic wall affected one patient received 2 times thoracic epidural blocks and thoracic nerve block. Scapalur and thoracic wall affected patient has been treated with SGB and 2 times thoracic epidural block. The chest and thoracic wall affected patient received 10 times intercostal blocks,2 times thoracic epidural blocks,3 times thoracic root block and neurolysis of intercostal nerves with absolute alcohol. The injected agents were 1% mepibacaine or 0.25% mercain heavy and methylprednisolone succinated, and at weekly intervals the agents were injected. Results : All patient having been treated with nerve blocks were free of pain at 3-9 months. Conclusion : Although no controlled trial has been done of nerve blocks to treat postherpetic neuralgia, this technique is safe in experienced hands and, if effected, may be repeated. It suggested that local anesthetics and steroid are the effective components in nerve blocks. Data on the relief of acute pain with nerve blocks, however cannot be extrapolated to predict the prevention of postherpetic neuralgia. The best way to prevent herpes zoster becasuse of post herpetic neuralgia is so difficult to treat.

This study researches an obesity inde( and the reaiities of physical activity of etementary school childrnl and pvide basic data to instruct correct physical activity for low weight md obese childraL The subject was 813 Elementary School Chiliherl of grade 4-6 in Krimgiu and data were collected with a Physical Activir Questionnaire from fTs, USA The collected data ware an3ly2ed with real number, pnfentagf avErge and standard deviation techniques. The rarlge was by SPSS WIN. Both of them were in the normal range, between -38.3 and 77.7, between low weight and obesity The results are as follows : 1. An Obesity index according to grade and sex: the average obesity index of 423 boys was 7.56 ± 15.7, for girls it was 2.56± 14.3. Both of them were in the nrnmal range, between -38.3 and 77.7. There were low weight(-38.85±0.9) students as well as obese, including extremely low weight children (-38.85 ±0.9) and extremely obese children. 2. On the whole, in the Freouency of the 25 item physical activities breakdown, children reported to watch TV 1.(2.7±0.6), or do homework(2.1 ±0.9), more than three-fourths of the week, male children, however, played more football(2.0 ±0.9). As male obese children do less MET5, MET8(highly active activity) than male normal children, it was also discovered that low weight children do mnre severe activity in MET8(high activity). In female cases, it was revealed that neither do highly intense activity. 3. In physical activitiy, male children received higher points than fonale children with 92.94±37.95 to 74.46 ±29.50. On the whole, male and female obese children had lower score than normal children. 4. As for attitude toward physical activiv, male children(31.9614.37) had a positive attitude than female children (29.57 ±3.89), but obese male children had a negative attitude regarding activity viewed as normal. ThaefgrE in peventing obesity in elementary school childrerl the treating of under-weight childrern. should be included in the obesity Fgram so as to Pevent mal-nutrition or denciency. It is needed to instruct obese childrul to carry out interlsive w[rk-outs at least 3 times a weft through systematic grams. It is also needed that parents and teachers educate elementary school chil(hell from an early age with iDcimation on the frequency and interlsity of work-outs to prevent obesity. It is also desirable that children be eddcated to cauy out physical activities that address thetr specific needs. As a result of this study, obesif management must be started from elementary school and children should be instructed to act in hiRh-interlsity actirities when they spend leisure time.

본 논문에서는 양측식 가동자석형 LDM을 대상으로, 고정자 권선을 단일 권선으로 성층할 경우 철심의 중앙부분에서 자기포화로 인해 정추력 발생이 어렵다는 단점을 보완하기 위해 고정자 철심을 분할 권선한 다분할 여자형 LDM의 설계방법을 제안한다. 이를 위해 자극과 코일 사이에 작용하는 힘(F)을 수직력(F_y)과 수평력(F_x)으로 나누어 해석하였으며, 영구자석 폭 대 여자권선 폭비를 추력의 왜형 및 리플이 최소화되도록 가변하여 유한요소해석 소프트웨어인 Maxwell-2D를 이용하여 해석하였다. 이러한 결과에 대한 타당성은 양측 다분할 여자형 LDM을 설계 제작함으로써 입증하였다. This paper was designed and analyzed the characteristics of linear DC motor(LDM) that be suitable to long stroke type. But, according to the magnetic saturation in the center core of the excitation coil of the stator, the control of LDM to get the constant thrust force of difficult because of the non-linearity of the inductance and the reluctance by the position of the slider. In this paper, by designing the width of the stator coil, double sided excitation LDM with multi-separated winding which is possible to obtain the constant thrust force is proposed. Using Maxwell 2D, which is the magnetic field analysis package, and proved the validity of design process, also the characteristics of LDM according to the variation of the design parameters of LDM was almost in accord with the experiment result.

Estradiol에 의한 흰쥐-자궁의 수축 기능과 Polyamine 대사의 변동에 관한 연구

이명아,고재홍,이영재,신경호,전보권,천연숙 고려대학교 의과대학 1995 고려대 의대 잡지 Vol.32 No.3

The polyamines have been postulated to be essential in most processes associated with both hypertrophy and hyperplasia. The effects of estrogen on uterine contractility vary with animal species, and most reports have shown that in vitro contractility of rat uterus is decreased after estrogen treatment, but estrogen increases polyamine contents in castrated rat uterus. This study was carried out to investigate whether the regulation of polyamine metabolism may be instrumental in the contractile response of castrated nonpregnant uterus of female SD rats to electrical field stimulation (40 V, 100 μsec : EFS). Estradiol (E2) increased uterine contents of putrescine (PT), spermidine (SPD), and spermine (SPM). These E2 effects were inhibited by tamoxifen or DFMO, but E2-incuced increase of uterine SPM content was enhanced by aminoguanidine. E2 decreased the amplitude of force developed in the rhythmic spontaneous contraction of rat uterus, but it exaggerated the increase of uterine contraction force in response to EFS. The E2-dependent exaggeration was inhibited by tamoxifen, DFMO, or indomethacin, but was significantly enhanced by aminoguanidine. The synergism between E2 and aminoguanidine on uterine contractility was little affected by indomethacin. These results suggest that E2-dependent increase of uterine contractility may be ascribed partly to increase of uterus polyamines.

항균성 동치미액의 첨가에 의한 냉면국물 중의 Salmonella typhimurium 및 Staphylococcus aureus 생육억제

소명환,조신호,이재우,이효구 한국식품영양학회 1999 韓國食品營養學會誌 Vol.12 No.2

동치미액은 전통적으로 냉면국물로 이용되어왔다. 냉면국물의 미생물 오염문제를 해결하기 위하여 항균활성이 높은 김치 젖산균 Lactobacillus homohiochii B21과 Leuconostoc mesenteroides subsp. mesenteroides C16을 스타터로 혼합사용하여 동치미액을 제조하고, 이를 냉면국물에 100%, 50%, 10% 및 0% 첨가하여 20℃ 및 10℃에서 보관할 때에 동치미액의 항균력으로 인하여 의도적으로 첨가한 Salmonella typhimurium과 Staphylococcus aureus의 증식이 억제되는 정도를 조사하였다. 동치미액 100%인 냉면국물은 20℃에서 보관할 때는 Salmonella typhimurium은 16시간만에, Staphylococcus aureus는 32시간만에 10^6CFU/ml에서 10^0CFU/ml로 각각 급격히 사멸하였고, 10℃에서 보관할 때도 시간경과에 따라 생균수가 급격히 감소하였으나 감소속도는 20℃의 경우보다 느렸다. 동치미액을 50% 첨가한 육수에서도 Salmonella typhimurium과 Staphylococcus aureus는 시간경과에 따라 급격히 감소하였으며, 감소속도는 동치미액 100%일 경우보다 느렸다. 동치미액을 10% 첨가한 육수에서는 20℃에서 보관할 때는 초기에 Salmonella typhimurium과 Staphylococcus aureus의 균수증가가 약간 있었으나 동치미액 무첨가에 비하여 현저히 억제되었으며, 8시간∼16시간 이후부터는 균수가 서서히 감소하였다. 육수에 동치미액을 첨가하지 않았을 경우에는 20℃에서 보관할 때는 초기부터 Salmonella typhimurium과 Staphylococcus aureus의 균수증가가 급격히 이루어졌으며, 10℃에서 보관할 때는 24시간 이후부터 서서히 증가하였다. Salmonella typhimurium과 Staphylococcus aureus에 대한 본 동치미액의 억제력은 후자의 미생물보다 전자에 대하여 더 강하게 나타났다. 본 연구의 동치미액을 육수에 50% 첨가하여 냉면국물을 제조한다면 보관중의 미생물 오염문제 해결에 큰 도움이 될 것으로 판단된다. Juice of Dongchimi, a Korean traditional vegetable food fermented with lactic acid bacteria, has been traditionary used as broth for Naengmyon, a Korean cold noodles with broth. This study was carried out to demonstrate the growth inhibition of two food poisoning bacteria, Salmonella typhimurium and Staphylococcus aureus, in Naengmyon-broth containing Dongchimi-juice fermented with high antibacterial lactic acid bacteria, Lactobacillus homohiochii B21 and Leuconostoc mesenteroides C16. Naengmyon-broths were made with beef broth and Dongchimi-juice fermented with lactic acid bacteria, and the changes in viable cell counts of the inoculated food poisoning bacteria in Naengmyon-broths were investigated during storage at 20℃ and 10℃. In Naengmyon-broth of 100% Dongchimi-juice stored at 20℃, the numbers of Salmonella typhimurium and Staphylococcus aureus were rapidly decreased from 10^6CFU/ml to 10^0CFU/ml in 16 hours and 32 hours, respectively. In Naengmyon-broth containing 50% Dongchimi-juice, their numbers were also rapidly decreased, though the decreasing rates were not so fast as those in 100% Dongchimi-juice. In Naengmyon-broth containing 10% Dongchimi-juice, the growths of the two food poisoning bacteria were markedly inhibited, compared with those in 100% beef broth, though some growths were occurred in early phase. But in Naengmyon-broth of 100% beef broth, their growths were very fast from early. Antibacterial activity of the Dongchimi-juice was more distinct at 20℃ than at 10℃, and was more active against Salmonella typhimurium than against Staphylococcus aureus.
