We reviewed 887 cases of esohagogram, 8863 cases of UGI series, 174 cases of small bowel series and 1926 casesof double contrast barium enema performed at the department of Radiology, Wonju College of Medicine from Jan. 1982 to Dec. 1984 to analyzed diverticula disease pattern of the GI tract in Korean. The results were as follows: 1.Esophageal diverticula The incidence was 3.27% and the sex ratio of male to female was 2.22:1 Age distribution wasrelatively even and most common in 5th decade. Most of them showed single in number, above 6mm sized and common inmiddle one third of both lateral side of esophagus. 2. Stomach diverticula The incidence was 0.07% and the sexratio of male to female was equal. Multiplicity was single in all cases. Most of them were above 11mm sized andcommon in gastric fundic area of greater curvature site of stomach. 3. Duodenal diverticula The incidence was1.51% and relatively even distribution in sex and age and common in after 5th decade. Most of them showed singlein number, 11-30mm sized and common in medial margin of 2nd portion of duodenum. 4. Colonic diverticula Theincidence was 2.34% and predominant in male and common in 5th. and 6th. decade. Most of them showed single innumber, below 5mm sized and common in right sided colon.

M-mode echocardiograms were recorded in 268 apparently healthy young male adults and the mitral valve motion during systole was analyzed. In 149 cases( 55.6%) out of 268 the predominant echo of mitral valve closure(CD line) was recorded as smooth line moving slowly anteriorly, in 48 cases(17.9%) the CD line showed an abrupt transient posterior motion during early systole, in 24 cases(9.0%) there were multiple additional echoes posterior to the CD line, 17 cases(6.3%) the mitral valve closure was recorded as pansystolic anteriorly concave echo deviating less than 2 mm from a drawn CD line, and 10 cases(3.7%) as curvilinear and anteriorly convex echo deviating from a drawn CD line. In the remaining 20 cases(7.5%), the mitral valve closure was recorded as pansystolic anteriorly concave echo deviating more than 2 mm from a drawn CD line, which was categorized to have mitral valve prolapse in the current study. However, there were no significant differneces in various echocardiographic dimensions of the heart and the aorta between those with and without mitral valve prolapse.

Human periodontal ligament fibroblast(hPDLF) is very important to cure periodontal tissue because it can be diverged into various cells. This study examined the expression of MMP-1, TIMP-1, periodontal ligament specific PDLs22, Type I collagen, Fibronectin, TIMP-2, telomerase mRNA in a replicative senescence of hPDLF. The periodontal ligament tissue was obtained from periodontally healthy and non-carious human teeth extracted for orthodontic reasons at the Chosun University Hospital of Dentistry with the donors' informed consent. The hPDLF cells were cultured in a medium containing Dulbecco's modified Eagle medium(DMEM, Gibco BRL, USA) supplemented with 10% fetal bovine serum(FBS, Gibco BRL, USA) at 37C in humidified air with 5% CO2. For the reverse transcription-polymerase chain reaction(RT-PCR) analysis, the total RNA of the 2, 4, 8, 16, 18, and 21 passage cells was extracted using a Trizol Reagent(Invitrogen, USA) in replicative hPDL cells. Two passage cells, i.e. young cells, served as the control, and beta-actin served as the internal control for RT-PCR The results of this study about cell morphology and gene expression according to aging of hPDLF using RT-PCR method are as follows: 1. The size of hPDLF was increased with aging and it was showed that the hPDLF was dying in the final passage. 2. PDLs22 mRNA was expressed in young hPDLF of the two, four, and six passage. 3. TIMP-1 mRNA was expressed in young hPDLF of the two and four passage. 4. There was a tendency that MMP-1 mRNA was weakly expressed over eighteen. 5. Type 1 collagen mRNA was expressed in almost all passages, but it was not expressed in the final passage. 6. Fibronectin mRNA was observed in all passages and it was weakly expressed in the final passage. 7. TIMP-2 and telomerase mRNA were not expressed in this study. Based on above results, it was observed that PDLs22, Type 1 collagen, Fibronectin, MMP-1. and TIMP-1 mRNA in hPDLF were expressed differently with aging. The study using the hPDLF that is collected from healthy patients and periodontitis patients needs in further study.

PURPOSE: To evaluate the early clinical results of lumbar microdiscectomy using minimally invasive tubular retractor (METRx-MD system, Medtronic Sofamor Danek, Memphis, TN), and to validate the merits of minimally invasive spinal surgery. MATERIALS AND METHODS: From April, 2003 to April 2004 we retrospectively studied a consecutive series of 45 patients who underwent lumbar microdiscectomy using minimally invasive tubular retractor. In all cases, minimally invasive approach using the tubular retractor were performed with a 2 cm sized paramedian incision. The following data were collected: clinical outcomes, operative time, intraoperative blood loss, need for blood replacement, time needed before ambulation, length of hospital stay, and complications. The clinical outcomes were assessed by the modified MacNab criteria. RESULTS: Minimally invasive tubular microdiscectomy was performed in 45 patients over a 12-month period with an average follow-up of approximately 8 months. The clinical outcomes assessed by MacNab criteria were excellent in 33 patients (73%), good in 10 patients (22%). The average operative time was 63 minutes (range, 35 to 95 minutes). The average blood loss was 62 mL (range, 50 to 110 mL). None of the patients needed blood replacement. With the exception of 2 patients, all patients could walk at the day of surgery. The average hospital stay was 2.3 days. None of the patients had dural tear, wound problem, or other complications. CONCLUSION: Lumbar microdiscectomy using tubular retractor can offer a useful modality for the treatment of lumbar herniated disc with the merits of minimally invasive spinal surgery. Further long-term, randomized, prospective investigations are needed to fully evaluate the impact of this technique.

Coronary arteriovenous fistula is a rare congenital coronary artery anomaly in adults. Most such fistula drain into a right heart chamber or into the pulmonary artery. Congenital left coronary artery-left ventricle fistula is even more uncommon. Aortography and selective coronary angiography are still the diagnostic mode of choice. However, recent studies have demonstrated that two-dimensional echocardiography with or without Doppler color flow imaging is a useful noninvasive tool in the diagnosis of coronary artery fistula. A 29 year-old female who had an exertional dyspnea, chest pain, and continuous diastolic murmur was referred to our hospital for further evaluation. The transthoracic two-dimensional and color Doppler echocardiography revealed a dilated left coronary artery which was drained into left ventricle. The coronary angiography showed that the left circumflex artery was very dilated and tortuous, and contrast medium passed from the left circumflex artery into the left ventricular cavity via a fistula. However, the right coronary artery and the left anterior descending artery were normal. We reported a case of an echocardiographically documented fistula between the left circumflex coronary artery and the left ventricle in young woman.
