A clinical and radiological observation was mde on 167 cases of urolithiasis among the number of 150 patientsduring 1 year and 6 months from June, 1981 to Nov. 1982. The results were summerized as follows. 1. There were 101man and 49 women, a ratio of 2:1. The ages of the patients ranged from 2 to 74 years, showing the highestincidence in 31 to 60 years(68.1%). 2. Locational distributions of urolithiasis were 80 cases (47.9%) in theureter, 66 cases(39.5%) in the kidney, 11 cases (6.5%) in the urethra and 10 cases (5.9%) in the bladder. 3. Amongthe 66 cases of renal stone, pelvis stone was 55 cases (83.3%) with staghorn types in 23 cases(34.8%), andcalyceal stone was 11 cases(16.6%). 4. The location of ureteral stone was 47.5% in lower, 40% in upper ureter and12.5% in mid-ureter. 5. The location of urethra stone was 82% in the anterior urethra and 18% in the posteriorurethra. 6. The chief complain of urolithiasis was flank pain in 59.2%, gross hematuria in 20.3%, renal colic in13.1% ,dysuria in 8.3%, nausea and vomiting in 4.7%, and sudden stoppage of urine stream in 3.5%. 7. Onurinalysis, gross hematuria was found in 54.4%, pyuria in 28.7%, bacteriuria in 23.3%, microscopic hematuria in18.5% and normal in 7.1%. 8. The size of urinary stone was 0.6-2.0cm in length in 105 cases(62.8%). 9. On I.V.P.study of renal stones(66 cases), mild and moderate hydronephrotic changes were detected in38 kidneys(57.5%), andthe relationsip between the urinary stasis and renal stone size was relatively good. 10. On I.V.P. study ofureteral stones(80cases), mild to severe hydronephrotic changes were detected in 64 kidneys(80%). 11. On K.U.B.film, paralytic ileus was found in 25 cases (14.9%). 12. Among the urinary stones, the radiolucent stones weredetected in 8 cases (4.7%). 13. Urinary stones diappeared in 11 cases (6.5%) spontaneously or medical treatment.

PURPOSE: The purpose of this study is to describe Magnetic Resonance(MR) findings of two epidural cavernous malformations of the spine. MATERIALS AND METHODS: MR imaging was performed in 2 patients(29-year-old man and 54-year-old woman). Sagittal T1 -, T2-weighted images and Gadolinium (Gd)-enhanced axial and sagittal images were acquired. Two patients had surgery and MR findings were compared with surgical and histopathological findings. RESULTS: MR imaging showed high- and low-signal intensity components of these lesions that were characteristic of an epidural cavernous malformation in one case. The other case showed a high signal intensity on T2- and strong enhancement on Gd-enhanced T1 -weighted images. We think that the former may be due to mixed subacute and chronic hemorrhage and the latter may be due to blood within the endotheliumlined sinusolds without hemorrhage. CONCLUSION: These findings were well correlated with the surgical and histo-pathological findings of cavernous malformation.

Intraspinal neurenteric cysts are rare congenital lesions that results from abnormal separation of germ layers in the third week of embryonic development, which may cause spinal compression. Although, the diagnosis of neurenteric cyst was very difficult prior to operation, MRI has proven to be a useful imaging modality in detection, localization and characterization of intraspinal neurenteric cysts. We recently experienced intraspinal neurenteric cyst in two patients who presented with progerssive quadriparesis. Myelography, CT myelography and MRI were taken and complete excision was performed. The MRI findings are presented and the literature is reviewed.

The mucoepidermoid carcinoma is a rare tumor in the lung. A case of bronchial mucoepidermoid carcinoma diagnosed by fine needle aspiration cytology is presented. The smear showed many intermediate cells with occasional mucus-secreting cells. Malignant squamous cells were not present. The cellular arrangement of intermediate cells was overlapping and grouped in ball-like fashion. These cytologic features are unique for diagnosis of this tumor.

49 strains of Pseudomonas aeruginosa were isolated from chronic wounds associated with orthopedic surgical field at Taegu armed forces general hospital. In the present report, authors have studied the Pyocin type of isolated strains by Gillies and Govans method. Also observed various interrelationship in associaton with Pyocin type, Pyocyanine formation, Oxidase reaction and antibiotic sensitivity. The results were obtained as follows; 1) Among the 49 strains tested in term of pyocin type, 41 strains(81.6%) were found to be typable and 8 strains (16.4%) to be untypable. Among the pyocin type of 41 typables, unclassified type was the most prominent type 17 strains (41.5%) and followed by type I(11 strains), 10 (3 strains), 5 (2 strains) and other type. 2) In the relationship among pyocyanine formation, oxidase reaction and pyocin type, no definite conclusion can be reached due to the paucity of tested strains except that more strains belong to the pyocin type I of the Pyocyanine negative strains. 3) In antibiotic sensitivity of isolated strains tested by plate dilution method, most of all strains were resistant to Kanamycin and Neomycin but few strains were moderate sensitive to Colistin, Polymyxin B, and Terramycin. 4) The Pyocin type of isolated strains were not related with antibiotic sensitivity to Colistin, Polymyxin B and Terramycin substantially.

Although several kinds of instrumentation systems are available for the transpedicular screw fixation in the treatment of spondylolisthesis, the clinical results and the difference between them remdins unclear. In order to study the feasibility of Zielke instrumentation system for that purpose, the author analysed the clinical results of 73 patients with mild or moderate degree of spondylolisthesis who were instrumented with the systems and followed up 25 months in average(Min. 12Ms). The results between the groups with different rod thickness in the system, 3.2mm(20 patients), 4mm(33 patients) and 5mm(20 patients), were compared to study the most appropriate thickness. Reduction of the deformity were done by aid of temporarilly applied Harrington system in 3.2mm group. Inlayed reduction potential coming from the jointing mechanism was utilized in the cases with less than 30% of slippage in 4 and 5mm group. Percentage of slippage was changed from 20% preoperatively, to 4% postoperatively and 6% at the end of follow up. The methods of fusion after reduction and fixation were anterior in 25 and posterolateral in 48. Bony fusion was achieved in all but one with pathological spondylolisthesis. Rod failures were observed in two of 3.2mm and one of 4mm group, and loosening of the joint were developed in three of 5mm group. Clinically, 93% of the patient showed excellent and good results at the end of follow up. From the results, we concluded that the instrumentation is a efficient method of treatment with several advantages in the reduction capacity and the stability of fixation. However, this system has several points in its mechanics that needs to be improved.

Normal C3WHeN strain mice exposed to topical 8inethoxypsomlen plus long wave ultraviolet (PUVA) showed a reduction in contact hypersensitivity, (CH) which was localized to the skin in the area of PUVA treatment (local suppression), whereas systemic PUVA treatment caused diffuse suppression of CH reaction, regardless of the application site of 2,4-dinitro-1-fluorobenzene (DNFB). There seem to be two different mechanisms responsible for CH reduction by PUVA. Local suppression by topical PUVA treatment was thought to be a result of blocking the afferent phase of immune response, it was associated with a lack of CH effector cells in the peripheral lymph nodes and could not be reversed by indomethacin treatment. Diffuse suppression induced by systemic PUVA treatment seemed to be associated with blocking of egress of effector cells from the regional lymph nodes, this depressed CH response was prevented when indomethacin was administered before PUVA treatment.

Emphysematous pyelonephritis is rare but freuently fatal complication of renal parenchymal infection, mostcommonly occurs in diabetic patients and is often associated with urinary obstruction, prior urologicalabnormality or infection. From 1898 to 1984 , about 50 cases of empysematous pyelonephritis have been reporteduniversally. The diaignosis of emphysematous pyelonephritis can be made only roentgenographically. In the last 2years, we have had two cases of emphysematous pyelonephritis at our hospital. It is our purpose to report twopatients who have survived wtih a brief review of the previous literature.
