We report one case of bilateral testicular torsion. A 400 gm male infant, born by cesarean section due to induction failure at 42 weeks gestation, was hospitalized at 9 days of age secondary to bilateral testicular mass. Physical examination revealed an healthy baby with enlarged, firm, nontender mass on both sides of the scrotum. Transillumination of the mass showed no transmission of light. Laboratory data included a normal CBC and a urinalysis. Ultrasonogrophy showed well encapsulated 0.9 x 0.9 x 1.0 cm sized and 1.5 x 1.3 x 1.3 cm sized homogenous hypoechoic solid mass in left and right testicles respectively, remainder testicular parenchyme showed normal structure. Exploration of the testes was performed at 25-days old under general anesthesia. Exploration revealed a infarction of the right testes secondary to spermatic cord torsion, evidenced by clockwise turns outside the tunica vaginalis of 270 degrees. Left testes was infarcted but a quarter of them seemed normal. Orchiectomy on right and fixation on left testes were performed respectively. Left spermatic cord seemed to be detorted spontaneously. Postoperatively the infant did well and discharged 5 days after operation. Follow up examination during the next 3 months have shown appropriated sized testicle with normal colorization and arterial pulse. Testicular scan performed at age 39 days showed good perfusion of left testes.

The main goals of treatment of malignant bone tumor are the prolongation of life survival and the improvement of quality of life. In growing children, however, leg length discrepancy (LLD) is one of major problem in the treatment of malignant bone tumors. Therefore, the precise understanding of growth in children is essential, and the prediction of LLD is critical in deciding the time and options of surgery. In addition, to use the adequate method of growth expectation, periodic follow-up and collaboration with patient's parents are needed.

The Her-2/neu protooncogene encodes a transmembrane tyrosine kinase that is structurally homologous to the receptor for epidermal growth factor. Its amplification and overexpression are associated with poor prognosis in breast cancer patients. Neu differentiation factor is a ligand for Her-2/neu protooncogene and was detected in ras-transformed rat fibroblasts. Heregulin (human homologue of neu differentiation factor) is a 44-kilodalton glycoprotein that stimulates tyrosine phosphorylation and induces growth arrest or stimulation and differentiation in human breast cancer cell lines. In this study we examined the expression of heregulin mRNA by nested reverse transcription (RT) PCR with fresh tissue, Her-2/neu protein, ICAM-1 and steroid receptors by immunohistochemistry, and DNA ploidy pattern by flow cytometry with paraffin-embedded tissue in invasive breast carcinoma. We compared the data with nodal status, lymphovascular invasion, steroid receptor status and DNA ploidy pattern. For RT-PCR to heregulin mRNA, 38 cases of fresh breast cancer tissue were obtained. Total 68 cases of invasive breast carcinoma tissue were fixed in formalin, which were used for routine histology, immunohistochemistry and flow cytometry. The results are as follows; 1) Heregulin mRNA was expressed in 86.1% of patients with invasive breast carcinoma and 100% of patients with benign breast lesion using nested RT-PCR analysis. 2) Her-2/neu protein was overexpressed in 50.0% of tumors using immunohistochemistry. The expression of Her-2/neu protein was significantly correlated with high counts of lymph nodes with metastasis (p<0.05), and high nuclear grade (p<0.05). 3) Her-2/neu protein overexpression was significantly correlated with a high DNA index(p<0.05). All of the tumors showing Her-2/neu protein overexpression and no heregulin mRNA expression revealed near tetraploid DNA content. However, both Her-2/neu overexpression and heregulin mRNA expressing tumors revealed near tetraploidy in 38.9% and diploidy in 50.0%. Based on these results, heregulin mRNA expression rate was 86.1% in human invasive breast carcinoma. Her-2/neu protein overexpression is associated with high positive lymph node number and DNA index. Statistically significant reverse correlation with lymph node metastasis is not present.

There are several different methods of purifying Treponema pallidum(TP) from rabbit testicular tissue. Among them, we compared the use of differential centrifugation, which has been most widely used, to Percoll density gradient centrifugatian, a newly applied method, in purifying TP from rabbit testicular tissue by checking the protein concentration of the TP suspension, hemagglutination assay using sheep erythrocytes sensitized by TP, IgM-TP-enzyme-linked immunosorhent, assay(IgM-TP-ELISA) and eJect,ron microscopic observation. The protein concent,ration af TP antigen suspension (2x10(8)TP/ml) purified by Percoll density gradient centrifugation (lower band) was the lowest (129.0pg/ml) when compared to those purified by differential centrifugation (324.0pg/ml) and Percoll density gradient centrifugatian (upper band) (560.2pg/ml). Sheep erythrocytes sensitized by TP purified by Percoll density gradient centrifugation(lower band) showed the same resiilts as those using a commercii1 TPHA kit when tested with positive and negative control sera. The sensitivity and specificity of the IgM-TP-ELISA were 88.5%(23/26') and 86.4%(19/2Z) respectively using TP as an antigen purified by differential centrifugation. The rates were 96.29% (25/26) and 95.5%(2l/22) using TP purified by Percoll density gradient centrifugation. As shown by the electron microscopy, T. pizllida purified by clifferential centritugation and Percoll density gradient centrifugatiori were structurally unaltered, and Percoll-purified TP contained much less tissue debris than TP prepared by differ ential centrifugation. Therefor e, Percoll density gradient centrifugation is considered to be a better method of purifying TP from rabbit testicular tissue when compared to differential centrifugatian, as a matter of fact, Perrol1 density gradient centrifugation has been applieci successfully in the study of the physiology, recombinant DNA techniques, and antigenic structure of TP and to the preparation of the antigen for the FTA-ARS and TP-ELISA

The adequate treatment of tibia fracture is one of the most difficult due to severe commiuntion, open wound, delayed union, angulation deformity and infection. We treated 38 fractures of the tibia by Interlocking intramedullary nail from Feb. 1983 to Mar. 1993. 35 cases of the tibia fracture were fresh, 13 cases of fracture were open. The other 3 cases were delayed union and nonunion. The Mean follow-up was 14.0 months. The results were as followings. 1. Of the 38 fractures, 37 fractures united and the mean union time was 18.7 weeks. 2. Interlocking intramedullary nail could be used to the majority of fractures of the proximal & distal tibia shaft. fractures. 3. The Im erlocking nail had rigid rotational stability and was appropriate for the treatment in severe unstable fractures, commninution and open-with bone loss. 4. Delayed union or nonunion was a good indication for intramedullary nailling. 5. The major-complication were valgus deformity of 2 cases, varus deformity of 1 case, 1 case deep infection. 6. Interlocking intramedullary nailing provided rigid fixation of . fracture and then made early joint motion exercise and ambulation.

This study investigated the stress of community residents in Kwang-Ju and Chonnam areas by using the General Health Questionnaire(GHQ-60) as a instrument of stress measurement. The number of subject were 445 residents who lived in three areas (large city, middle city, and rural area) and they were individually interviewed in March, 1994. The result of study showed that the degrees of stress measured by GHQ-60 were statistically significant in the residents' area, age. sex variables: (a) the residents in middle city among three area had the highest level of stress: (b) the resident who were more than 60 in age had the highest level of stress: (c) the female resident had more stress than male residents: (d) particularly, the residents who were more than 60 years old in the middle city had the highest level of stress. Further, the results of factor analysis showed that there were three factors of social dysfunction, depression and anxiety, and psychosomatic symptom. The social dysfunction factor was statistically significant in both age and resident area variables. The depression and anxiety factor was statistically significant in the residents' area, age. sex variables. The psychosomatic symptom factor was statistically significant in both age and sex variables. The study suggested that they should give a special attention to solve the old people's stress because stress was closely related to residents age.

OBJECTIVES: To evaluate the urinary concentrations of hydroxyridinium crosslinks of collagen in patients with osteoarthritis(OA) or rheumatoid arthritis(RA), and to compare its clinical correlation with the classic indices of the disease activity of RA. METHODS: Concentrations of urinary pyridinoline (Pyd) and deoxypyridinoline(Dpd) were measured in urinary samples collected from 18 control patients, 35 patients with OA, 45 patients with RA by competitive enzyme immunoassay using microplate coated with monoclonal antibody. RESULTS: 1) Mean urinary concentrations of Pyd in OA patients were 33.5nmol/mmol creatinine, in RA patients were 50.0nmol/mmol creatinine which were higher than the values in controls (25.1 nmol/mmol creatinine). Also, mean concentrations of Dpd in OA patients were 9.2nmol/mmol creatinine, in RA patients were 10.1nmol/mmol creatinine which were higher than the values in controls(5.6nmol/mmol creatinine)(p<0.01). 2) Mean urinary concentration of Pyd was 50.0 nmol/mmol creatinine in RA patients, which was significantly higher than the values in OA(33.5 nnmol/mmol creatinine)(p<0.05), but the mean Dpd concentratians were not significantly different between the two groups. 3) The concentrations of urinary Pyd in RA patients was significantly correlated with the biologic markers indicating inflammatory activity such as ESR(r=0.68, p<0.001), CRP(r=0.72, p<0.001) and the number of tender joint(r=0.66, p<0.01) CONCLUSION: Urinary concentrations of Pyd and Dpd were significantly higher in OA and RA patients than in controls, Especially urinary Pyd concentrations were significantly increased in RA patients than in OA patients, and strongly correlated with disease activity index of rheumatoid arthritis. The mean Dpd concentration, bone specific analogue, in RA patients was not significantly different from that of OA patients and it was not correlated with disease activity index Thus measurement of urinary Pyd might provide a sensitive, noninvasive biochemical marker for studying activity of RA.
