Ninety two injuries of the main nerves in the upper extremity observed in 79 patients, were studied at the Department of the Orthopedic Surgery, 17th Army Hospital from May 1965 to Aug. 1968. The treatment given consisted of neurolysis in 15, neurorrhapy in 77(primary 43 and secondary 34) and tendon transplantation and transfer in 11 cases. The results for the median, ulnar and radial nerves after primary and secondary suture were analyzed with respect to the level of injury(high and lower). The results of the median nerve repair were more succesful than those of the ulnar nerve, In these two nerve injuries, the sensory recovery was better than the motor and secondary suture gave better results than primary suture. Thirteen cases failed to respond to primary or secondary nerve repair, among those tendon transfer or tendon transplantation was tried in eleven cases, from the latter approximately 25% of motor recovery could be seen.

Tentative diagnosis of meniscal pathology is very helpful for the successful operative management including arthroscopy. Conventional arthrography has long been used to meet this purpose, but it has some limitations due to complex views and some difficulties in imaging the whole anatomical structures. Recent diagnostic advancement produced post-arthrographic HRCT and MRI for the compensation of these problems of conventional arthrography. Arthrography and post-arthrographic HRCT has been carried out on 49 knees in 43 patients. 38 knees among them could be confirmed by arthroscopy and following results were obtained. 1. Diagnostic accuracies of post-arthrographic HRCT for medial and lateral meniscal injuries of knee were 94.7% and 92.1% repectively. 2. Shape, contour of torn meniscus and the relationships between the torn fragments were better demonstrated with HRCT. 3. Horizontal tear could also be suspected by HRCT. 4. Peripheral detachment could be differentiated with synovial recess on the HRCT, especially in the reformat view, but was more clearly visible in arthrography. 5. Arthrography and HRCT can be used as a good complementary study for the evaluation of meniscal injuries.

Allogenic peripheral blood stem cell transplantation could be used instead of allogenic bone marrow in treatment of leukemia in children. This 10-year-old female patient with high-risk acute lymphoblastic leukemia received a myeloablative regimen followed by allogenic peripheral blood stem cell transplantation from an HI A-identical sibling donor. Neutrophil recovery to greater than 500/pL occurred at day 11 and platelets recovered to greater than 20,000/pL at day 13. Allogenic peripheral blood stem cell transplantation can be performed safely and may result in a rapid neutrophil and platelet engraftment, without any apparent increased risk of acute graft versus host disease.

Recently, studies on mitochondrial DNA (mtDNA) have increased rapidly. Conventional parameters, such as diversity index, pairwise comparison, are used to interpret and validate data on autosomal DNA; however, the use of these parameters to validate data from mitochondrial DNA databases (mtDNA DBs) needs to be verified because of the different transmission patterns of mtDNA. This study was done to verify the use of these conventional parameters and to test the "coverage concept" for a new parameter. The mtDNA DB is not very big; however, it is necessary to check how the change in parameters corresponds to the DB size. For this, we artificially rearranged a Korean DB into several small sub-DBs of variable sizes. The results show that the diversity in nucleotide variations and the different haplotype numbers do not vary as the size of DB increases. However, the "coverage" changed a lot. The coverage increased from 0.113 in a DB of 100 people to 0.260 in a DB of 653 people. Additionally, using the "coverage concept", we predicted how the total number of haplotypes changed with variations in the sub-DB size and compared the predicted result with final result. In conclusion, "coverage", in addition to conventional statistical parameters, can be used to check the usability of an mtDNA DB. Finally, we tried to predict the size of the whole mtDNA number in Korea using "saturation concept".

BACKGROUND: We evaluated the performance of Modular Analytics (Roche Diagnostics, Basel, Switzerland) which is combined with automated chemiluminescent immunoassay analyzer and automated chemical analyzer

in order to assess its utility for the improvement of efficiency of routine immuno-chemistry workstation. METHODS: Within- and between-day precision, linearity, and recovery rates were evaluated for 21 items (T3, T4, TSH, E2, LH, Testosterone, FSH, prolactin, AFP, CEA, CA125, CA19-9, total PSA, CRP, ASO, RF, Ig G, Ig M, Ig A, C3C, and C4). Commercialized controls(Roche Diagnostics, Basel, Switzerland) and patient sera for test specimens were used. Centaur(Bayer Diagnostic Division, New York, USA) and LX 2200(Eiken Chemical Co., Tokyo, Japan) were used as the control analyzers to evaluate the correlation. RESULTS: Within-day Coefficients of variation(CVs) was below 5% for all the analytes and between-day CVs was below 5.0% except ASO(8.01%). The linearity was excellent(r2>0.999; slope, 0.98-1.02; p<0.001). Recovery rates for all analytes were in the range of 95% to 103%. The correlation coefficients between modular and Centaur was exceeded 0.971, and between modular

and LX2200 exceeded 0.910, except RF(r=0.834). (P<0.05) CONCLUSION: The recently developed Modular Analytics proved to be highly precise and linear for quantitative analysis of hormones, tumor markers, and serum proteins in routine immuno-chemistry workstation. Correlations with Centaur and LX 2200 were thought to be good.

PURPOSE: Interleukin(IL)-16 is a potent chemoattractant factor for CD4+ T cells, monocytes, and eosinophils. It up-regulates IL-2R on CD4+ T lymphocytes and regulates the function of antigen presenting cells. We used retrovirus-mediated gene transfer of the human IL-16 gene into the neuro-2a cells, which is the murine neuroblastoma cell lines, to investigate whether locally secreted IL-16 might generate anti-tumor immune responses. METHODS: We estimated whether the local secretion of IL-16 from the genetically-modified tumor cells would affect their tumorigenicity in vivo, and then, IL-16 transfected neuroblastoma cells would protect mice from tumor development after wild-type tumor cell challenges. And we investigated the mechanism of IL-16 by nude mice trial of an anti-tumor immune response. RESULTS: The IL-16 gene-transduced neuro-2a clones secreted 4.2-6.0ng of IL-16 per mL per 10(5) cells during 24 hr. None of the mice(N=6) injected with 2x10(6) of irradiated, IL-16 gene-transfected neuro-2a cells developed tumors within 6 weeks while all of the mice(N=6) injected with wild-type neuro-2a cells developed tumors. Immunization of mice(N=6) with 2x106 IL-16 gene- transfected, irradiated neuro-2a cells protected these animals against a subsequent challenge with 2x10(6) wild-type tumor cells. Nude mice also showed an anti-tumorigenicity effect. However, the mice did not reveal the prophylactic effect against murine neuroblastoma. CONCLUSION: The local secretion of IL-16 gene-transduced tumor cells abrogated their tumorigenicity and induced protective immunity.
