197 spine CTs were performed from 29th, March 1982 to 7th March, 1984. Among them, 39 patients preoperatively diagnosed as herniated nucleus pulposus ar bulging disc with CT and myelography were operated. 43 disc spaces ofdisc disease were analysed in true positive and false negative cases. Finally the accuracy, sensitivity and specifictiy of spine CT and myelography ar calculated. The resuslts are as follows; 1. The CT findings of disc diseases are in order of frequency, asymmetrical obliteration of epidural fat (82%), ventral indentation orcompression on dural sac(72%), focal protrusion of disc(64%), root changs

In children, snapping knee syndrome and joint pain with the loss of physiological hyperextension strongly suggests a diagnosis of a torn discoid meniscus. We performed arthroscopic meniscectomy to treat torn discoid lateral meniscus on 19 knees and open meniscectomy on 9 knees of 26 children(average age: 10.9 yrs) from September, 1983 to October, 1993 at Guro hospital. According to Ikeuchi's grading system', excellent results were obtained in 14, good in 11, fair in 2 knees and poor in 1 knee which was associated with osteochondritis dissecans. The knees treated by partial meniscectomy showed less Fairbank's radiologic changes than those by total meniscectomy during the average follow-up 4.2 years(minimum 1 year, maximum 7 year 11 months).

The study was undertaken to assess the CT density of the antibiotics solution. CT scan of six antibioticssolution-streptomycin, chloramphenicol, Na-penicillin, ampicillin, kanamycin and cefamezine-in concentration ofabout 33% (approximatly single dose of intramuscular injection) was performed, using plastic syringes. Variousconcentrations of striptomycin, chloramphenicol and Na-panicillin were also examined for evaluation of relationbetween concentration and the CT density of the antibiotics. In addition, relationship between CT number andmathematically calculated effective atomic number and electron density of the antibiotics was evaluated. Theresults are as follows; 1. The CT densities of all antibiotics reveal high density (CT number 80–150) inconcentration of single intramuscular injection dose. 2. CT number of striptomycin, chloramphenicol andNa-penicillin gradually increased with increase of concentration of the antibiotics, producing linear proportionto concentration, effective atomic number and electron density of the antibiotics. 3. Therefore, density ofantibiotics should be included in differential diagnosis when high density on CT scan is observed.

BACKGROUND: In the skin, it is often difficult to differentiate lymphomas from reactive lymphoid lesions by light microscopic examination. OBJECTIVE: Our purpose was to determine whether immunologic data obtained from mutine-processed specimens could be used to further objective morphologic interpretations. METHODS: We conducted an immunohistochcmical staining in 44 cases of benign and malignant cutaneous lymphoproliferative lesions using nine antibodies, including anti-CD3, UCHL1, MT1, MT2, L26, MB2, BerH2, 123C3, and MIB1. RESULTS: 1. Immunophenotyping with anti-CD3, UCHL1, MT1, L26, and MB2 was useful for the diagnosis of T cell or B cell lymphoma. However, these antibodies showed a lack of specificity for neoplastic cells, 2. Antibody to CD56, 123C3 showed positivity in 4 cases of angiocentric lymphoma, but negativity in 8 cases showing angiocentric lymphoma-like pathology. 3. Antibody to CD30, BerH2 showed positivity in all 6 cases of CD30 positive large cell lymphoma, but negativity in 6 cases showing diffuse lymphoma-like pathology. 4. Antibody to Ki-67, MIB1 showed positivity in more than 30% of infiltrating cells in 6 cases of angiocentric lymphoma, 4 cases of diffuse B cell lymphoma, and in more than 60% of infiltrating cells in 6 cases of CD30 positive large cell lymphoma. CONCLUSION: These observations suggest that immunostaining may provide useful adjunctive information in distinguishing benign from malignant cutaneous lymphoproliferations in paraffin sections.

Peyronie's disease is an idiopathic disorder of the penis that is unusually associated with erectile dysfunction. We treated 7 cases of Peyronie's disease associated with erectile dysfunction by implantation of malleable penile prostheses(AMS 600) and multiple full thickness transverse incision of the tunica albuginea corresponding to fibrotic plaque. Postoperatively the penile curvatures were corrected in all patients, who were able to engage in sexual intercourse as well . There were no complications such as pain or recurrence of penile curvature. Therefore, we recommend the incision of plaque and implantation of penile prostheses as the worth surgical methods in treatment of patients with Peyronie's disease associated with erectile dysfunction.

We designed a new electrophoresis apparatus. This was consisted of the body into which agarose could be poured directly and the cover from which the platinium electrodes were suspended. After running the nucleic acid in this electrophoresis, we observed the band of nucleic acid on the ultraviolet transilluminator without touching the agarose gel, keeping the cover with the electrodes and discarding the gel in body. We compared the variuos types of the electrophoresis apparatus. In the electrophoresis apparatus which body was consisted of the flat bottom, the migration of dyes was the fastest among studied types. The high migration velocity of dyes was due to high electric current.
