Magnetic resonance imaging(MRI) is accepted as a useful tool for the diagnosis of injury of the knee recently. The anterior cruciate ligament tear is accompanied by the damage of the osseous and soft tissue of the knee. The occult osseous lesion is found on magnetic resonance imaging as bone density change that is not found on the simple radiograph. From Jan. 1992 to Apr. 1994, magnetic resonance imaging was performed on 44 patients with acute anterior cruciate ligament tears. MRI was done within 6 weeks of the index anterior cruciate ligament injury. The criteria of decreased signal intensity on the Tl weighted image and increased signal intensity on the T2 weighted image was applied for the incidence assessment of the occult osseous lesion. After arthroscopy with or without ACL reconstruction, follow-up simple radiograph was checked every 3 months. Occult osseous lesions were documented in 32(73%) of the 44 patients. Of the 32 patients with bony lesion, 81% had lesions of the lateral compartment. Lateral femoral condyle was involved in 15 cases(46.9%), and lateral tibial plateau in 22 cases (68.8%). Follow-up X-ray revealed no joint deperession in all of the 32 patients with the occult osseous lesion. This result suggests that there is a high correlation between the occult osseous lesion of lateral compartment of the knee on magnetic resonance imaging and anterior cruciate ligament tear. The presence of the occult osseous lesion in the patient with acute anterior cruciate ligament tear did not affect rehabilitation and weight bearing.

In Korea, all domestic made test systems for detecting antibodies in HIV-1 contain the antigens from human immunodeficiency type 1 (HIV-1) subtype B. However, because HIV-1 subtype O is significantly different in amino acid sequences from all other subtypes of HIV-1, there has been a need for developing a test for detecting antibodies in subtype O. For this purpose, the entire nucleotide sequence corresponding to the extracellular domain of the transmembrane glycoprotein of HIV-1 subtype O was synthesized with consideration of Escherichia coli cordon usage. Various regions of the extracellular domain were cloned into E. coli expression vectors and tested for levels of protein production. The nucleotide sequence, named ECTM, that can encode a 129 amino acid-long peptide, was found to be expressed at a high level in E. coli. The protein of approximately 17 kDa specifically reacted with sera from individuals infected with HIV-1 subtype O. The ECTM protein was purified to near homogeneity by the CM-T gel chromatography, using concentrated, denatured inclusion bodies. In Western blot analysis, the purified viral antigen reacted with sera from individuals infected with subtype O more efficiently than subtype B. The enzyme linked immunoabsorbent assay (ELISA) system was developed using the subtype O viral protein and compared with the commercially available kit lacking the antigens from subtype O. The ELISA kit containing the subtype O antigen ECTM alone efficiently reacted with sera from individuals infected with subtype O. The subtype O antigen-containing kit produced a positive absorbence even when sera were diluted 512-fold, suggesting a high sensitivity. The commercially available kit also reacted with subtype O sera, but produced a negative result at a dilution of 8-fold. Our results suggest that the currently available kit may not be able to efficiently detect subtype O sera and that the viral protein developed in this study may be added to the current system to maximize the detection of sera from individuals infected with subtype O.

A 66 year old man with history of dizziness and occasional headache for a month was found to have right subclavian steal syndrome confirmed by angiogram. Right radial pulse is very weak. Blood pressure on left is 130/70mmHg and on right 70/50. Marked Bruits are audible on right side of neck and shoulder area.

The cystoscopic manipulation was performed in 82 cases of lower ureteral stones, 7 cases of mid ureteral stones and 4 cases of upper ureteral stones who visited the Department of Urology, during the period of 24 months from January 1st, 1984 to December 31st, 1985. Using Dormia stone basket in 73 cases and ureteral meatomy was performed in 20 cases and the results were as follows: 1. Dormia stone basket was used in 73 cases of ureteral stone. Immediate removal was successful in 24 cases, delayed removal in 37 cases (48 hours delay), so successful removal of stone was in 61 out of 73 cases. Failure in 12 cases, spontaneous delivery of stone was noted in cases 5 about 4-20 days after the application of Dormia stone basket did not pass through the portion of calculi and spontaneous delivery of stone was made in 14 cases after meatotomy. 2. Successful removal of stone was, mostly in proportion to the size of stone. 3. In 4 cases of upper ureteral stone, successful removal after indwelling of Dormia stone basket the position of stone for 48 hours. 4. Post management complications were fever in 12 cases, flank pain and low abdominal pain in 78 cases.

BACKGROUND: Controversy exists as to whether or not inhalation anesthetics and intravenous anesthetics impair arterial oxygenation (PaO2) during one lung ventilation (OLV). Accordingly, we examined the effect of enflurane and propofol on PaO2 and pulmonary vascular resistance (PVR) during OLV. METHODS: Forty patients, who had prolonged periods of OLV anesthesia with minimal trauma to the nonventilated lung were studied in a cross over design. Patients were randomized to four groups; Group 1 received 1 MAC of enflurane and oxygen from induction until the first 20 min after complete lung collapse, then were switched to propofol 100 g/kg/min (P100). In group 2, the order of the anesthetics was reversed. Group 3, Group 4 received the same order of the anesthetics as Group 1, Group 2, respectively but received propofol 200 g/kg/min (P200). RESULTS: During OLV, the PaO2 values were lower than those with two lung ventilation (TLV), there were no significant differences among each groups and between propofol and enflurane in PaO2, but in the selected patients (n=10, PaO2<120 mmHg during OLV), PaO2 in propofol group was higher than that of enflurane group (p<0.05). Conversion from TLV to OLV caused a significant increase in PVR, but there were no difference in PVR between propofol and enflurane group. CONCLUSIONS: These results suggest that the usual clinical dose of propofol affords no advantage over 1 MAC of enflurane anesthesia except low PaO2 patients during OLV. Propofol might be of value in risk patients of hypoxemia during thoracic surgery when OLV is planned.
