The vaso-epididymography and vasoseminal vesiculography is the only diagnositc method for investigating thepatency and abnormal lesion of male genital system radiologically. The author performed 53 cases ofvaso-epididymography and vasoseminal vesiculography in Busan National University Hospital during the 8 years from1973 to 1981. All patients complained of primary infertility more than a year and were confirmed azoospermia onsemen examination, and 23 cases of them underwent testicular biopsy. The results are as follows; 1. The agedistribution were mainly between 26 and 35 years old (83.0%). 2. The infertile duration were almost from 1 to 5years(86.8%). 3. The past history associated with infertility was gonorrhea, tuberculosis and scrotal trauma. 4.Of the 23 cases of confirmed by testicular biopsy, the pathologic findings were normal spermatogenesis in 12 cases(52.2%) and hypospermatogenesis or arrest type in 11 cases (47.8%). 5. Non-filling sites of contrast media onvas-epididymography and vasoseminal vesiculography were epididymis(83.0%), ejaculatory duct (41.5%) and seminalvesicle (24.5%), were commonly bilateral (68.0%) and were more prevalent in the right side than left (1.2:1.0). 6.The abnormal findings of ejaculatory ducts, seminal vesicles, vas ampullas and vas deferens were mainly strictureof obstruction, obstruction of dilatation, beaded appearance or obstruction and obstruction respectively. 7. Inthe epididymis, there was almost obstructive lesion at the tail portion(83.0%).

BACKGROUND: First of all, this study was performed to assess the result of curative radiotherapy and to evaluate different possible prognostic factors for squamous cell carcinoma of the supraglottic larynx treated at the Pusan National University Hospital. The second goal of this study was by comparing our data with those of other study groups, to determine the better treatment policy of supraglottic cancer in future. METHODS AND MATERIALS: Thirty-two patients with squamous cell carcinoma of the supraglottic larynx were treated with radiotherapy at Pusan National University Hospital, from August 1985 to December 1996. Minimum follow-up period was 29 months. Twenty-seven patients (84.4%) were followed up over 5 years. Radiotherapy was delivered with 6 MV photons to the primary laryngeal tumor and regional lymphatics with shrinking field technique. All patients received radiotherapy under conventional fractionated schedule (once a day). Median total tumor dose was 70.2 Gy (range, 55.8 to 75.6 Gy) on primary or gross tumor lesion. Thirteen patients had induction chemotherapy with cisplatin and 5-fluorouracil (1-3 cycles). Patient distribution, according to the different stages, were as follows: stage I, 5/32 (15.6%); stage II, 10/32 (31.3%); stage III, 8/32 (25%); stage IV, 9/32 (28.1%). RESULTS: The 5-year overall survival rate of the whole series (32 patients) was 51.7%. The overall survival rate at 5-years was 80% in stage I, 66.7% in stage II, 42.9% in stage III, 25% in stage IV ( p= 0.0958). The 5-year local control rates after radiotherapy were as follows: stage I, 100%; stage II, 60%; stage III, 62.5%; stage IV, 44.4% ( p=0.233). Overall vocal preservation rates was 65.6%, 100% in stage I, 70% in stage II, 62.5% in stage III, 44.4% in stage IV ( p=0.210). There was no statistical significance in survival and local control rate between neoadjuvant chemotherapy followed by radiotherapy group and radiotherapy alone group. Severe laryngeal edema was found in 2 cases after radiotherapy, emergent tracheostomy was done. Four patients were died from distant metastsis, : three in lung, one in brain. Double primary tumor was found in 2 cases, one in lung (metachronous), another in thyroid (synchronous). Ulcerative lesions were revealed as unfavorable prognostic factor ( p=0.0215), and radiation dose (more or less than 70.2 Gy) was an important factor on survival ( p=0.0302). CONCLUSIONS: The role of radiotherapy in the treatment of supraglottic carcinoma is to improve the survival and to preserve the laryngeal function. Based on our data and other studies, early and moderately advanced supraglottic carcinomas could be successfully treated with either conservative surgery or radiotherapy alone. Both modalities showed similar results in survival and vocal preservation. For the advanced cases, radiotherapy alone is inadequate for curative aim and surgery combined with radiotherapy should be done in operable patients. When patients refuse operation or want to preserve vocal function, or for the patients with inoperable medical conditions, combined chemoradiotherapy (concurrent) or altered fractionated radiotherapy with or without radiosensitizer should be taken into consideration in future.

PURPOSE: This study was to determine the incidence and severity of venous irriation in patients receiving vinorelbine tartrate (Navelbine ) in combination chemotherapy. MATERIAL AND METHODS: Twenty four patients histologically confirmed non-small cell lung cancer were enrolled in this study who receiving vinorelbine in combination chemotherapy through a peripheral vein from Oct. 1997 to Mar. 1999 with retrospective study design method. One group was 6~10 minutes infusion rate, the other was 10~20 minutes infusion rate with the same free-flow intravenous infusion. RESULTS: A total of 126 infusions were observed in this study. Sixty-two infusions were admi nistered at the 6~10 minutes, and 64 infusions were administered at the 10~20 minutes. The incidence of any venous irritation was 3.2% (2/62) in the group that received the infusion in 6~10 minutes and 10.9% (7/64) in 10~20 minutes (p=0.164), so we could not acquire any statistical significance. However the incidence of severe venous irritation (grade 3, 4) was 0% (0/62) in 6~10 minutes infusion group and 9.4% (6/64) in 10~20 minutes infusion group. There was a significant difference between two groups (p=0.028) CONCLUSION: Our results suggest that venous irritation associated with vinorelbine tartrate infusion can be reduced by shorter duration of administration and vinorelbine tartrate might be recom mended to administer at 6~10 minutes infusion in clinical practice.

BACKGROUND: Neuropathic pain produced by nerve injury has the characteristics of enhanced pain responses - allodynia. To understand the pathophysiology of the neuropathic pain, We evaluated the effect of NMDA antagonists and chemical sympathectomy on the c-fos mRNA expression. METHODS: We have divided rats(Sprague-Dawley, N=24) that their left L5 and L6 nerve were tightly ligated into two groups. In NMDA antagonist group(N=17), We injected 10 g MK801 and 10 g 5-amino-phosphonovalerate in three ways, intrathecally before the ligation, after ligation and subcutaneous continuously. Then behavioral tests for mechanical allodynia and cold allodynia were performed. After the test of allodynia,the expression of c-fos were assessed by Northern blot hybridization. In chemical sympathectomy group(N=7), We injected 70 mg/kg guanethidine into the peritoneum in two ways, before the ligation and after ligation. Then same methods were performed in NMDA antagonist group as well. RESULTS: Intrathecal NMDA antagonists before the ligation supressed the elevation of c-fos mRNA expression. Intrathecal NMDA antagonists on the 7 days after the ligation reduced the c-fos mRNA expression and neuropathic pain. Continuous treatment of subcutaneous NMDA antagonists supressed the development of neuropathic pain and the elevation of c-fos mRNA expression. Chemical sympathectomy before the ligation did not supress the elevation of c-fos mRNA expression. Chemical sympathectomy on the 7 days after the ligation reduced neuropathic pain and the elevation of c-fos mRNA expression. CONCLUSIONS: NMDA receptor is related to the induction and maitenance of neuropatic pain, and sympathetic nervous system has a main role in the already induced neuropathic pain.

Salmonella infected aneurysm of aorta is one of the local complications by systemic salmonellosis. We have experienced a case of the rupture of infected abdominal aortic aneurysm in 47-year old man. He was admitted because of 39degrees C fever, abdominal pain, back pain of 7 day's duration. Diabetes mellitus had been diagnosed previously, but not managed. Abdominal CT scans showed aneurysmal dilatation with periaortic air bubbles and severe atherosclerotic change of abdominal aorta from renal hilum to the iliac bifurcation level. Blood cluture yielded Salmonella group B strains. He was treated with intravenous ceftriaxone, metronidazole, ciprofloxacin. On the seventh hospital day, the patient showed sign of shock with blood pressure 80/60 mmHg and comatous conciousness. Abdominal CT scans revealed the rupture of infected aneurysm of abdominal aorta just superior to the iliac artery bifurcation. The patient had not underwent surgery, then he was expired.

The surface characteristics of titanium have been shown to have an important role in contact ossseointegration around the implant. Anodizing at high voltage produces microporous structure and increases thickness of surface titanium dioxide layer. The aim of present study was to analyse the response of rat calvarial osteoblast cell to commercially pure titanium and Ti-6Al-4V anodized in 0.06 mol/l beta-glycerophosphate and 0.03 mol/l sodium acetate. In this study, rat calvarial osteoblasts were used to assay for cell viability and cell proliferation on the implant surface at 1, 2, 4, 7 days. 1. Surface roughness was 1.256micrometer at 200V, and 1.745micrometer at 300V. 2. The thickness of titanium oxide layer was increased 1micrometer with the increase of 50V. 3. The proliferation rate of osteoblastic cells was increased with the increase of the surface roughness and the thickness of titanium oxide layer. 4. There was no difference in cell viability and cell proliferation between commercially pure titanium and Ti- 6Al-4V anodized at the same condition. In conclusion, the titanium surface modified by anodizing was biocompatible, produced enhanced osteoblastic response. The reasons of enhanced osteoblast response might be due to reduced metal ion release by thickened and stabilized titanium dioxide layer and microporous rough structures.
