Osseous union of congenital pseudarthrosis of the tibia remains today a formidable challenge to orthopedic surgeons. Recently clinlcal studies of nonunion, congenital pseudarthrosis, and fresh fracture suggest that the electical stimulation enhances the union rate and shortens the healing time. We treated a case of congenital pseudarthrosis of the tibia by combined Boyds dual onlay graft and direct current electrical stimulation. A flrm clinical and radiological union was obtained at four months posfoperatively.

Pigmentary demarcation lines are borders of abrupt transition between more deeply pigmented skin and that of lighter pigmentation. We describe two patients with pigmentary demarcation lines associated with pregnancy symrnetrially involving the buttocks and flexor as jects of legs. Hormonal changes in pregnancy and compression by the enlarged uterus of Sl and S2 peripheral nerves may be responsible for these changes.

Lung cancer is the most common malignant tumor worldwide and its incidence continues to rise each year. Recent development of molecular biologic method has led to advances in determining the etiologic factors of lung cancer and the establishment of cell lines has provided a lot of information on the through chemosensitivity, radiation biology studies, cytogenetics, and molecular biologic studies, which permits improved treatment for lung cancer. We established a small cell lung cancer cell line, designated JePa-1, obtained from malignant pericardial effusion of small cell lung cancer patient and characterized its morphologic and molecular biologic features. the JePa-1 cell line grew relatively slowly (doubling time 45hrs) as very loosely adherent floating aggregates growing in small clumps with distinct cell outlines and intertwined cords. Also JePa-1 cell line secreted antidiuretic hormones. Electronmicroscopic examination revealed that JePa-1 cell line and xenografts contained electron dense core granules, characteristic of being of neuroendocrine origin. To investigate the tumorigenic capacity, the JePa-1 cell line was injected into SCID and nude mice. Tumors taken from xenografts were observed in 3 out of 4 of the SCID mice and 2 out of 4 of the nude mice. The histologic characteristics of the xenografts were similar to those of the cell line and the original cytologic finding of the pericardial fluid, suggesting small cell carcinoma. The results of immunohistochemical markers showed reactivity for Rb protein, c-myc, TGF-alpha, TGF-beta , EGFR, keratin, NSE, chromogranin, and EMA. The DNA ploidy and the index of the JePa-1 cells was tetraploid and 2.13, respectively. The positive rate for the Rb, c-myc and K-ras proteins of the JePa-1 cell line were 98.9%, 99.3%, and 99.7% respectively as determined by flow cytometry. Cytogenetic analysis using the G-banding technique showed 65 chromosomes with various numerical and structural abnormalities. On examination of the expression of TGF-alpha, TGF-beta , and EGFR by PCR, only the EGFR was positive Through the establishment of JePa-1 cell line, we report in this paper the characterization of a small cell lung cancer such as morphologic and immunocytochemical features, growth characteristics in culture, hormone production, expression of oncoprotein and several growth factors, tumorigenicity, chromosomal abnormalities, and DNA ploidy and index. The JePa-1 cell line will be valuable in vitro studies for the etiology, treatment and the prognostic factors in small cell lung cancer.

Afferent loop syndrome(ALS) is caused by obstruction of the afferent loop after subtotal gastrectomy with Billroth II gastrojejunostomy. Prompt diagnosis of ALS is important as perforation of the loop occurs. The aim of this study is to ascertain the value of sonography and CT to diagnose ALS. We describe the radiologic findings in ten patients with ALS. The causes of ALS, established at surgery, included cancer recurrence (n=4), internal hernia(n=4), marginal ulcer (n=1), and development of cancer at the anastomosis site(n=1). Abdominal X-ray and sonography were performed in all cases, upper GI series in five cases and computed tomography in two cases. The dilated afferent loop was detected in only two cases out of ten patients in retrospective review of abdominal X-ray. ALS with recurrence of cancer was diagnosed in three cases by upper GI series. Of the cases that had sonography, the afferent loop was seen in the upper abdomen crossing transversely over the midline in all ten patients. The causes of ALS were predicted on the basis of the sonograms in three of the five cancer patients. In two cases of computed tomography, the dilated afferent loop and recurrent cancer at the remnant stomach were seen. Our experience suggests that the diagnosis of afferent loop syndrome can be made on the basis of the typical anatomic location and shape of the dilated bowel loop in both sonography and computed tomography.

Assays for HBsAg, HBV DNA, anti-HBc and anti-HBs of 285 units of packed red blood cells supplied by Taegu Red Cross Blood Center were performed to evaluate the correlation between the prevalence of HBV DNA and the serologic markers for hepatitis B virus. None of 285 plasma samples was positive for HBsAg, however, HBV DNA were detected by polymerase chain reaction in 2 samples which both presented only with anti-HBc positivity.. Of 204 samples tested for anti-HBs, 96 samples(47.1%) were positive and among 216 samples tested for anti-HBc, 80 samples(37.0%) were positive. Of 193 samples tested for both anti-HBs and anti-HBc, 80(41.1%) were all negative and 48(24.9%) were positive on both tests. Those samples which showed positivity only to anti-HBc were 25(13.0%). Considering the above results, transfusion-transmitted hepatitis B virus infection could be prevented by discarding anti-HBc positive blood, however, that may bring insufficient supply of donor bloods in the country like Korea where the prevalence of anti-HBc is high. Anti-HBc positive blood unequivocally positive for anti-HBs should be considered noninfectious for HBV and should be allowed to be transfused. It would reduce the amount of discarding donor blood as the routine blood donor screening tests presently used at Korea Red Cross Blood Center supplemented by anti-HBs and anti-HBc testing.
