본 연구는 치수조직, 치은, 치주인대로부터 배양된 조직을 SP (Substance P)로 4시간, SP, CGRP (Calcitonin Gene-related Peptide), Tumor necrosis factor-α (TNF-α)로 8시간 자극 후 RNase Protection Assay를 시행하고, IL-8의 분비량을 측정해 다음 결과를 얻었다. 1. IL-8 mRNA는 모든세포에서 발현됐다. 2. IL-8 mRNA 발현은 SP (10^(-5)M)와 SP (10^(-8)M)로 4시간 자극 시 증가되지 않았다. 3. IL-8 mRNA 발현은 SP (10^(-4)M)와 CGRP (10^(-6)M)로 8시간 자극 시 증가되지 않았다. 4. TNF-α (2 ng/㎖) 자극 시, IL-8 mRNA 발현이 증가됐다. 5. 치은 세포를 CGRP (10^(-6)M)로 8시간 자극 시, IL-8 분비량이 증가했다 (p < 0.05). 6. 치주인대 세포를 SP (10^(-4)M)로 8시간 자극 시 IL-8 분비량이 증가했다 (p < 0.05). We investigated the secretion of Interleukin-8 (IL-8) from ginviva and periodontal ligament stimulated with Substance P (SP) and Calcitonin Gene-related Peptide (CGRP). Gingiva (GF), periodontal ligament (PDLF) and pulp (PF) tissues were collected from extracted instact 3rd molars. Cultured cells were stimulated with different concentrations of SP for 4 hrs, and stimulated with SP, CGRP and Tumor Necrosis Factor-α (TNF-α) for 8 hrs. Then RNase Protection Assay was carried out. ELISA was performed using supernatants of stimulated cells for quantitative analysis of IL-8. Results were assessed using supernatants of stimulated cells for quantitative analysis of IL-8. Results were assessed using student t-test with significance of P < 0.05. According to this study, the results were as follows: 1. IL-8 mRNA was detected in all type of cells studied (PF, GF and PDLF). 2. IL-8 mRNA expression was not increased after stimulating 4 hrs with SP (10^(-5)M) and SP (10^(-8)M) compared with Mock stimulation in all type of cells studied. 3. IL-8 mRNA expression was not increased after stimulating 8 hrs with SP (10^(-4)M) and CGRP (10^(-6)M) compared with Mock stimulation in all type of cells studied. 4. TNF-α (2 ng/㎖) increased the expression of IL-8 mRNA in all kind of cells studied. 5. The secretion of IL-8 from GF was increased 8 hrs after the stimulation with CGRP (10^(-6)M) (p < 0.05). 6. The secretion of IL-8 from PDLF was increased 8 hrs after the stimulation with SP (10^(-4)M) (p < 0.05). Calcitonin Gene-related Peptide (CGRP) increased Interleukin-8 (IL-8) which plays an important role in chemotaxis of neutrophil in Calcitonin Gene-related Peptide (CGRP) gingival tissue, whereas Substance P increased the secretion of IL-8 from periodontal ligament.

A ten months old, female Yorkshire terrier weighing 2.88 kg referred to veterinary teaching hospital of college of veterinary medicine, Konkuk University because of syncope, cough and dyspnea. First hematological and serum chemical test revealed thrombocytopenia, mild anemia, and increase of concentration of ALP (195 U/L). On 57 days later, second hematological and serum chemical test revealed polycythemia, increase of concentration of ALP (211 U/L), and Tchol (387 mg/dl). Right atrium enlargement, main pulmonary artery bulge and cardiomegaly (VHS = 11.5) were observed in radiographic findings. Ultrasonographic images showed both right and left ventricular dilation and turbulent flow between the descending aorta and the main pulmonary artery in color Doppler imaging. ECG showed left ventricular enlargement, SA block, and electrical alternant. Thoracotomy was performed through left fourth intercostal incision under isoflurane anesthesia. Patent ductus arteriosus was double ligated with 1-0 silk. Cough and dyspnea disappeared on 5 days after operation. Turbulent flow was not found in color doppler imaging of ultrasonography on 10 days after operation. Ten months later after the operation, syncope could not exist any more.

Appendicitis is the most common acute abdomen in Emergency Medical Center & outpatient department. But sometimes, it is difficult for us to diagnose because of clinically variable symptoms. We reviewed the ultrasonographic findings and analyse 521 cases of appendectomy patients about its distribution of sex and age, seasonal prevalence, clinical symptom and signs, laboratory findings, duration from onset of symptom to arrival at hospital, duration from arrival at hospital to operation, vital signs, operative results, and associated diseases, which were treated at the department of General Surgery & Emergency Medical Center in Chung Ang Gil Hospital from July, 1994 to June, 1995. The results were as follows : 1. The most common age group was second decade. And male to female ratio was 1.43:1. Seasonal variation was not significant. 2. Of 521 cases, 141 cases(27.1%) visited the hospital within 24 hours from the onset of symptom, and 259 cases(49.7%) visited between 24 to 48 hours. 3. In duration from arrival to operation, the cases within 6 hours were 263 (50.5%), the cases between 6 and 12 hours were 131(25..1%). 4. In systolic blood pressure, cases below 90mmHg were 19(3.6%), cases above 160mmHg were 23(4.4%). Below 60mmHg diastolic pressure were 55 cases(10.6%), cases above 110mmHg were 9(1.7%). In pulse rate, above 90 rate/min were 171(32.8%). 5. On admission leukocytosis was found in 413 cases(79.3%) and 342 cases of them were pathologic appendicitis. 6. Ultrasoundgraphy was performed in the 87 cases, but 23 cases were suggested appendicitis. Among 23 cases, 22(95.7%) revealed pathologic appendicitis at ooperation and labortatory examination. Of the 64 cases which were normal on ultrasonography, only 2 cases(3.1%) were proved to be appendicitis. 7. The results of 496 operations without ultrasonography were appendicitis in 390 cases(78.6%), mesenteric lymphadenopathy 36(7.3%), pelvic inflammatory disease 28(5.6%), fecalith 15(3.0%), terminal ileitis 8(1.6%), diverticulitis 7(1.4%), urinary tract stones 5(1.0%), cecal cancer 2 cases, right ovarian tumor 2 cases, tubo-ovarian abscess 2 cases, grater omentum internal hernia 1 case. Our results showed that the sensitivity of ultrasonohraphy was 95.8% and the specificity 98.4% in the diagnosis of appendicitis, It suggests that the ultrasonography is very helpful in the diagnosis & differential diagnosis of acute appeendiditis.

재발한 지주막하 포도낭미충증의 Albendazole 치험 1예

김성범,박대원,이재갑,정혜원,송준영,손장욱,김민자,박승철,제보경,김정혁,이진수 대한감염학회 2003 감염과 화학요법 Vol.35 No.5

뇌실이나 뇌기조에 발생하는 포도낭미충증은 매우 드물며 유구조충 유충의 머리부분이 변성되면서 발생하는 낭성 막의 비정상적인 성장을 특징으로 한다. 이러한 유형의 병변은 지름술 후에도 진행적인 경과를 보이며 아직까지 항기생충제를 이용한 치료 사례들이 적고, 따라서 가장 적절한 치료 기간도 알려져 있지 않다. 본 증례 보고는 재발한 실비우스 틈새의 포도낭미충증 환자에서 4주간의 albendazole과 스테로이드로 효과적으로 치료하였던 예이다. 환자는 praziquantel과 뇌복막지름술로 치료를 받고도 포도상의 뇌실질외형의 병변이 악화되어, 뇌척수액 투과가 좋은 것으로 알려진 albendazole로 치료제를 바꾼 뒤 병변의 수와 크기가 감소였으며 이후 2년 간의 추척기간동안 다른 발작 없이 잘 지내고 있다. 지주막하의 포도낭미충증은 albendazole과 corticosteroid 치료에 잘 반응하는 것으로 보인다. The so-called racemose cysticercosis, a rare variety of neurocysticercosis occurring in ventricles or basal cisterns, is characterized by abnormal growth of cystic membranes with degeneration of Taenia solium heads (scolex). Although lesions of this type are known to follow a progressive course even after ventricular shunting, there are limitations of case series treated with antiparasitic drugs, and the optimal duration of the treatment is not yet known. We report a case of relapsed racemose cysticercosis in the Sylvian fissure, who has been successfully treated with albendazole and adjunct corticosteroid for 4 weeks. The patient had been previously treated with praziquantel and ventricul-operitoneal shunt, and maintained on the anticonvulsant drug for one year, but returned to the hospital due to seizure recurrence. The patient has been well in seizure-free state for the follow-up 2 years after albendazole therapy. The subarachnoid racemose cysticercosis seems to respond well to treatment of corticosteroid along with prolonged albendazole.

김건년,이보나,박효덕,신상모,공경준,장동근,김병철,권혁채,이봉희 경북대학교 센서기술연구소 1998 센서技術學術大會論文集 Vol.9 No.1

A wafer rolling etching system for the silicon bulk micromachining has been designed and fabricated. The silicon diaphragms were anisotropically etched in a 24.5 weight percent KOH solution. Compared to the conventional KOH etching systems, pyramidal hillocks, and wave-shaped structures on the etched surfaces were greatly reduced by using this system. After etching for time of 438 minutes, the average etched depth and the etch-rate were measured to be 537μm and 1.22μm/min, respectively. The average etching uniformity of etching depth was 0.87% in 5-inch wafer. Our results showed that the wafer rolling method enhanced etch uniformity and etch rate.

Background: Recombinant IFN-beta products have been approved for the treatment of several diseases. Recently, Inbionet, Co. has successfully developed rhIFN-beta product, Genebeta. This study was performed in a purpose of confirming the biological activity of Genebeta by comparison with another recombinant IFN-beta, Beneserin which was already approved. Methods: In vitro antiporliferative activity, regulation of MHC class I expression, antiviral activity, regulation of natural killer cell cytotoxicity were studied for functional comparison of these two rhIFN-beta products. Results: Proliferation assay data showed that two recombinant IFN-beta inhibited T cell and Daudi cell proliferation to a similar extent. When antiviral activity was compared, there was no significant difference between them. The treatment of these two rhIFN-beta also resulted in a similar level of upregulation of class I expression on the surface of A549 cells. Cytotoxicity experiment against tumor cells revealed that both of rhIFN-beta could enhance NK cell cytotoxicity to comparable level. Conclusion: All comparison data indicated that rhIFN-beta products, Genebeta and Beneserin have comparable potentials as a biological response modifier.

교통사고로 내원한 접형척추(butterfly vertebra) 환자 1예 보고

염석란,이근,박철완,양혁준,현성열,류일,진욱 대한응급의학회 2001 대한응급의학회지 Vol.12 No.3

A butterfly vertebra is a rare, but very important congenital anomaly that must be differentially diagnosed with compression fracture of the vertebral body. It has characteristic findings on simple X-ray, CT, and MRI. These findings are an anterior wedging contour on the sagittal image, a widening of the transverse diameter on the coronal image, adaptations of nearby vertebral endplates on the sagittal image, communicated intervertebral disc spaces on the sagittal and the coronal images, a well-defied midline bony defect with a sclerotic margin in the vertebral body on the axial image, and a normal body signal intensity on MRI. Because of legal problems and further plans for treatment, close attention must be given to patients who complain of back pain and who have decreased anterior height of the vertebral body after trauma. In those patients, a butterfly vertebra must be differentially diagnosed with compression fracture of vertebral body. We report one such case here.
