The authors reviewed serial chest films of 113 patients of spontaneous pneumothorax which were treated byclosed tube thoracotomy during the period from May, 1979 till July, 1982 in CNUH. The resuls are as follows; 1.Male was more frequently affected than female, and the sex ratio was 3.5:1. 2. 71.1 per cent of patients were over31 years of age. 3. Of the 113 cases, 51.3 per cent were on the right, 48.7 per cent on the left. 4. The mostcommon underlying pulmonary disease was pulmonary tuberculosis(39.8), the next was belb or bullar (17.7%), and thelast was pneumonia(8.8%). 5. Pneumothorax was the most common type in pulmonary tuberculosis(66.7%), andpyopneumothorax in pneumonia(80.0%). 6. Among 103 cases in complete re-expansion of collapsed lung after closedthe thoracotomy, 39.5 per cent was expanded completely within 1 week in presence of visceral and/or parietalpleural thickening, and 86.2 per cent in none of it. According to the degree of pneumothorax, the more severedegree of pneumothorax, the more delay in re-expansion times. 7. Most common chest finding after re-expansion ofcollapsed lung was pleural thickening(51.4%).

The radiologic findings of lumbosacral spine and measurement of lumbosacral angle were analysed in 238 with backache and 102 without backache which were visited at Chungnam National University from March 1980 to July 1981.The measurement of lumbosacral angle was based on a method of Fergson. The results obtained were as follows; 1. The age group of 18 to 29 years was most common in backache group and the male was affected more frequently than the female with the ratio of 1.9 to 1. 2. In patients with backache, the overall mean lumbosacral angles were 44.2±2.6 degrees in male and 35.8±2.0 degrees in female. In patients without backache, in control group, the overall mean lumbosacral angles were 32.6±0.7 degrees in male and 33.4±1.4degrees in female. 3. In control group, difference of means between male and female was about 1degrees in patients with backache, the overall mean lumbosacral angles were increased about 12degrees in male and 2degrees in female than control group. In patients with and without backache, no significant difference of lumbosacral angle between the 4 age groups was present. 4. In backache group, increased lordosis was more common and increased lumbosacral angle than the decreased lordosis. 5. In backache group, lumbosacral angle of abnormal radiologic findings in lumbosacral spine was significantly increased than control group. 6. In patients with backache, radiologic findings and its lumboscral angles were alumbosacral anomaly 56 cases (23.5%): 46.9 degrees, increased lumbar lordosis 46 cases (19.2%): 48.1 degrees, osteoarthritis 44 cases(18.5%) : 40.8 degrees, decreased lumbar lordosis 30 cases (12.6%): 29.9 degrees, in order, And these radiologic findings were similar with many other authors.

BACKGROUND: HLA antisera are procured mainly from placental blood or blood of multiparous women. The latter has a merit that a large volume of antisera could be obtained, once the antisera are found to be of good quality. METHODS: A total of 1,437 multiparous blood donors were screened for the presence of anti- HLA antibodies. After the first screening with 20 panel cells, initially reactive sera were re- screened with 30 panel cells. RESULTS: Of 1,437 sera, 50 sera (3.5%) were reactive to both the first and the second screening panel cells. Among 50 sera, 25 (50.0%) sera could be assigned for their antibody specificity with r value of 0.8 or more. Only 14 samples (1.0%) showed reactivity to two or more panels with same antigen specificity and strength index of 80% or more. Four donors repeatedly donated blood with specificities of A24, A26, B7, and B7+B40, respectively. CONCLUSIONS: Screening of HLA class I antibodies in multiparous blood donors showed that HLA antisera of good quality could be obtained in about 1% of the donors in Korea.

The organ transplantation process requires the interdisciplinary team approach, including the transplantation-surgery doctor, the nurse, the coordinator, the medical social worker, etc. Because the legislation of the organ transplantation and "brain death" remains under consideration, we have still some arguments on legal, social, and ethical issues of organ transplantation, especially in Korea. In this study, we analyse the 29 cases of validity evaluation of donation, and 28 donors who voluntarily registered for organ donation. Also we review the role of medical social worker in the organ transplantation team and the social work process in the live organ donation and cadaveric donation. To prevent anticipating problems with social, legal and ethical issue, as a member of the organ transplantation team, the medical social worker verifies the validity of unrelated donation, gets the informed consent from the family of the brain death patient and tries to exclude the commercialism of transplantation. In addition, the medical social worker can extend the mood of altruistic donation and encourage the people to do the valid donation for the helpless chronic patients.

The study was conducted to compare the side effects in myelography of the two non-ionic water-soluble contrastmedias, Iopamidol(Niopam) and Metrizamide(Amipaque). A total of 111 patients were examined, 64 with Iopamidol and47 with Metizamide. Side effects consisted of headache, nausea, vomiting, dizziness, urinary difficulty, muscularpain, seizure, neurobehavioral distrubance, neurologial sign change, vital sign change and etc. The common sideeffects were headache, nausea, vomiting and dizziness in order of frequency. Most of the side effcts were subsidedwithin 24 hours following meylography. Iopamidol myelography caused fewer and milder side effects than Metrizamidestudy. The side effects were more commonly observed in cervial, thoracic or total myelography than in lumbarmyelography with either lopamidol or Metrizamide. There was no significant correlation between incidence of theside effects and premedication with phenobarbital or valium injection before myelography and CSF sampling duringthe procedure.

In patients with early colorectal cancer, intraoperative localization of the target lesion is troublesome. Several strategies have also been studied for the preoperative localization of colorectal tumors. These include CT colonography, endoscopic metal clipping, endoscopic tattooing, and intraoperative colonoscopy. On the other hand, preoperative tattooing can lead to technical failure for effective tattooing or result in intraperitoneal complications. To minimize these adverse events, several studies performed tattooing with the patient's blood.

BACKGROUND: Hepatitis B virus (HBV) DNA quantification is important for the management of HBV infection and identification of the development of resistance. The susceptibility to contamination and more variable reproducibility of results with the conventional HBV DNA quantification method have raised the need of a more simple and accurate method for HBV DNA quantification. Real-time quantitative PCR assays recently introduced in the laboratory can meet these needs. In this study, we evaluated the performance of the Real-Q HBV Quantification kit developed in Korea. METHODS: We evaluated the recovery of DNA extraction, the interference of internal control, an analytical sensitivity, specificity, and reproducibility, a clinical specificity, and a reportable range of the Real-Q HBV Quantification kit. The quantification result was also compared to that obtained by the Digene Hybrid-Capture II. RESULTS: The mean percent recovery was 108.6% and there was no interference with the internal control on DNA extraction. None of HIV, hepatitis C virus, or cytomegalovirus showed a cross-reactivity with HBV. This assay detected HBV DNA in a linear range from 10(2) to 10(10) copies/mL, with the detection limit of 56 copies/mL. The assay exhibited a low within-run CV (coefficient of variation) (8.7-11.9%), between-run CV (10.5-14.7%), and between-day CV (13.2-21.4%). No HBV DNA was detected in any of 100 samples without HBV, resulting in a clinical specificity of 100%. The levels of HBV DNA showed a good correlation with those determined with Digene Hybrid-Capture II (R2=0.9827). CONCLUSIONS: The Real-Q HBV Quantification kit showed a good analytical sensitivity, specificity, and high reliability with a broad reportable range. This assay should be clinically useful in managing patients with HBV infection.
