Poland's syndrome which is associated with thoracic anomaly and ipsilateral syndactyly is not hereditary and is of unknown origin. It was described first Alfred Poland in 1841 year. This syndrome affects males more frequently than females. We have experienced two cases of Polands syndrome who were all male and each case revealed thoracic anomalies; abscent pectoral muscles and anterior axillary fold, pectus excavatum, and ipsilateral syndactyly with aplasia or hypoplasla of the middle phalanx.

Concurrent use of instrumentation has been shown to increase fusion rates and satisfactory results for surgical treatment of the lumbar stenosis. The objectives of the present study were to evaluate clinically and radiologically two groups of lumbar stenosis who were surgically treated with pedicular screw fixation system and posterior lumbar interbody or posterolateral autogenous bone graft following complete posterior decompression. One group was degenerative type and the other group was spondylolisthetic type spinal stenosis. We analyzed the results of 39 cases of lumbar stenosis who underwent pedicular screw and rod fixation system and posterior lumbar interbody or posterolateral autogenous iliac bone fusion following complete posterior decompressive operation during the period from May 1988 to December 1992. There were 27cases of degenerative type and 12 cases of spondylolisthetic type lumbar stenosis. The were 25 women and 14 men. Their age was ranged 20 to 76 years old with an average of 51.7 years old. The follow up period was the interval from 18 months to 6 years with an average of 3.2 years. The radiologic union rate was average 94.9% and 96.3%(26cases) in degenerative spinal stenosis and 91.7%(11 cases) in spondylolisthetic spinal stenosis. The clinical success rate was average 92.3%(36 cases), 88.9%(24 cases) in degenerative spinal stenosis and 100%(12 cases) in spondylolisthetic spinal stenosis. The patients with spondylolytic spinal stenosis showed better result in their life than the patient with degenerative spinal stenosis.

PURPOSE: Since the discovery of estrogen receptor-beta(ER-beta, five C-terminal variants of ER-beta were identified. We designed this study to investigate the pattern and clinical implications of ER-betaand its splicing variants expression in normal and malignant mammary tissues. METHODS: Using reverse transcription polymerase chain reaction (RT-PCR), we examined the expression levels of ER-alpha and ER-betaand its five splicing variants (beta1, beta2, beta3, beta4, beta5) in 50 paired normal and cancer tissues. We measured the densities of RT-PCR products using Tina version 2.10 (Raytest, Germany). Firstly, the incidence and intensity of ER-alpha and ER-beta and its five splicing variants were compared. Then the expression of ER-betamRNA splicing variants was also analyzed with regard to the ER-alphaprotein expression measured by immuno-histochemical staining and the menopausal status of the patients. Chi-square test and paired samples t-test were used for statistical analysis. Differences were considered to be significant with a p-value of less than 0.05. RESULTS: The expression of ER-betamRNA variants in normal breast and cancer tissues were as follows: ER-beta2 (100%/100%), ER-beta4 (76%/74%), ER-beta5 (32%/58%), and ER-beta1 (14%/16%). ER-beta3 was not detected at all. In terms of intensity, we observed a significant decrease of ER-beta2 (P<0.001) and an increase of ER-beta5 (P=0.004) in the mRNA expression levels among breast cancers compared to the corresponding normal breast tissues. Compared to the corresponding normal tissues, a significant decrease of ER-beta2 in cancer tissues was observed in patients with ER-alpha-positive (P<0.001), with age over 50 (P=0.01), and under 50 (P=0.04) as well, but not in patients with ER-alpha-negative (P=0.48). ER-beta4 also significantly decreased in patients with ER-alpha-positive (P=0.004) and with age over 50 (P=0.07). ER-beta5 showed a significant increment only in patient aged over 50 (P=0.04). CONCLUSION: ER-alpha mRNA expression significantly increases but ER-beta mRNA expression decreases in the cancer tissues compared to the corresponding normal tissues. Among ER-beta variant forms, ER-beta2 is predominant in both normal and malignant mammary tissues and ER-beta4, ER-beta5, and ER-beta1 in descending order but ER-beta3 does not express in mammary tissues. The decrease of ER-beta2 and ER-beta4 expression is prominent in cancer tissue especially in ER-alpha-positive cancers, which suggests that ER-beta2 and ER-beta4 may possess a regulatory function in mammary carcinogenesis. Further investigations to verify the roles of ER-beta variants are mandatory.

The CD8(+)CD28(+) T cells have known to mediate major histocompatibility complex class I-restricted cytolysis and to secret an HIV-1 inhibitory factor. As HIV infection lead to dramatic changes within the cellular immune system, the cellular cytotoxicities decrease in the duration of the HIV infection. To determine the importance of the cellular cytotoxicities in long-term nonprogression, we tried to compare CD28 expression on total T, CD4(+) T, and CD8(+) T cells as one of methods for cellular cytotoxicity measurements between long-term nonprogressor and normal person or between long-term nonprogressor and rapid progressor. The median percentages and counts of CD4(+) T cells of the norrnal, the long-term nonprogressor, and the rapid progressor groups were 39.9 and 0.96 * 10(9) cells/L, 24.6 and 0.58 * 10(9) cells/L, 9.9 and 0.15 * 10 cells/L, respectively. As a result of comparison of the cells having CD28 surface molecules on CD8(+) T cells in the long-term nonprogressor and the rapid progressor group, they showed over 5 times lower than that in the normal group. Especially, the long-term nonprogressor regarded to the healthy HIV-infected patient showed much lower CD28 expression on total T, CD4(+) T, and CD8(+) T cells than those of the normal person. The proportions of CD4'CD28 T and CD3CD28 T cell subsets showed the significant difference between the LTNP and the RP group. In conclusion, although HIV-infected patients were LTNPs having the steady CD4(+) T cell counts and no clinical symptoms, we suggested that HIV led to abnormality within the lymphocyte subsets such as the altered expression of CD28 molecules on various T cell subsets and this result would cause deficiency of host immune function and failure of control of HIV replication by anergy in T cell subsets.

PURPOSE: To describe soft-tissue radiographic and high-resolution CT findings of radiation-induced lung injury of rabbit over time and to correlate them with pathologic findings. MATERIALS AND METHODS: 15 rabbits were irradiated in the right lung with one fraction of 2000 cGy. After 4, 6, 12, 20, 24 weeks, 3 rabbits in each group were sacrificed and soft-tissue radiographs and high-resolution CT of their lung tissue were obtained. Radiological findings were correlated with pathologic findings. RESULTS: On soft- tissue radiogram, radiation pneumonitis shown as consolidation with air-bronchogram occurred in 3 cases after 6 weeks, and in 1 case after 12 weeks of irradiation. In addition, pneumonic consolidation with adjacent pleural contraction was seen in 2 cases after 12 weeks of irradiation. Fibrotic changes indicated by decreased volume occurred after 20 weeks and combined bronchiectatic change and bronchial wall thickening appeared after 20 weeks(N=1), and 24 weeks(N=3). HRCT findings of radiation pneumonitis were homogeneous, increased attenuation after 4 weeks(N=3), 6 and 12 weeks (each N=I), patchy consolidation after 6 and 12 weeks(each N=2), discrete consolidation after 12, 20 and 24 weeks(each N=I) and solid consolidation after 20 and 24 weeks(each N=2). Pathologically radiation pneumonitis and pulmonary congestion were seen after 4 and 6 weeks. After 6 weeks, collagen and reticulin fibers were detected along alveolar wall. Mixed radiation pneumonitis and fibrosis were detected after 12 weeks. 20 weeks after irradiation, fibrosis was well defined in interstitium and in 24 weeks, decreased number of alveoli and thickening of bronchial wall were defined. CONCLUSION: Radiation pneumonitis was provoked 4 weeks after irradiation on rabbit lung and progressed into radiation fibrosis 20 weeks after irradiation on soft-tissue radiographs and high-resolution CT. High-resolution CT is more precise in detecting early radiation pneumonitis and detailed pathologic findings.
