This study was carried out to elucidate the cytokine mRNAs expression and morphological features according to a microglial proliferation and apoptosis in a rat lumbar spinal cord, after a right sciatic nerve transection. The control group was composed of 5 rats (Spraque-Dawley) and the experimental group was composed of 70 rats. On post operation day (pod) 1, 2, 3, 5, and 7 eight rats were sacrificed on those days. On pod 10 five rats were sacrificed as well as five rats sacrificed on post operation weeks 2, 3, 4, 5, and 6. On light microscopy, activated microglia were often found in a perineuronal position around motoneurons in the ventral gray matter and more randomly distributed throughout the neuropil in the dorsal gray matter of lumbar spinal cord. GSA I-B4-positive microglia began to increase from 1 day after transection, and reached peak at 2~3 days and it persisted at 5~7 days and decreased thereafter. TUNEL-positive microglia was not observed in control group and began to increase from 5 days after transection and increased gradually until 3 weeks and decreased thereafter. On in situ RT-PCR, the positive signal for IL-1alpha and IL-6 mRNA was found mainly in the cytoplasm of the activated microglia and astrocytes at 1 day after transection and showed stronger signal at 3 days and decreased gradually until 10 days. TNF-alpha mRNA was detected 1 day after transection and remained for 7 days and localized to activated microglia as well as probably some astrocytes. The signal intensity of IL-1alpha and IL-6 mRNA was generally stronger than TNF-alpha mRNA. On transmission electron microscopy, there were chromatin condensation with margination toward nuclear membrane and condensation of cytoplasm at 3 days after transection. Apoptotic bodies were found after 5 days and increased gradually until 3 weeks. According to the above findings, it is concluded that apoptosis appears to be one mechanism by which activated microglia are gradually eliminated and cytokine expression seems to played an active role in the microglial turnover.

Hobnail hemangioma(HH) is a benign acquired vascular tumor of endothelial origin which should be differentiated from other malignant vascular neoplasm such as Kaposi's sarcoma or angiosarcoma. We report a case of hobnail hemangioma in a 21-year-old woman who had a dusky-red patch on her left shin. Histologically, ectatic vascular channels with a single layer of plumped endothelial cells were seen and the vascular channels seemed to dissect the collagen bundles. She underwent treatment with surgical excision with primary closure.

This study was designed to evaluate the clinical manifestations and results of operative treatment in penile injury during erection. We reviewed 18 cases of penile injury during erection from December 1992 to June 1996. Of 18 patients, 14 patients were treated with early operation, 3 patients with conservative treatment and followup was 1 to 31 months (mean: 14.1 months). Patients age ranged from 23-76 years old (mean: 39.6 years), common cause of the injury was sexual intercourse (8 cases), masturbation (3 cases) and finger-pressure (2 cases) in order. Of 8 patients who occurred during sexual intercourse, 7 patients were married. The injury developed at midnight in 8 cases (44%), early morning in 7 cases (39%) and the other times in 3 cases (~7%). Of 14 patients who received with early operation, 13 patients revealed rapture of the corpus cavernosum and 1 patient revealed rupture of superficial dorsal vein. The site of penile fracture showed proximal shaft in 8 cases (62%), midshaft in 3 cases (23%) and distal shaft in 2 cases (15%) in order. The overall complication rate of early operative treatment was 15% (2 of 13 cases) compared to a complication rate of 100% (2 of 2 cases) for conservative treatment. In conclusion, our experience demonstrates that the most common cause and site of penile injury are sexual intercourse and proximal shaft, early operative treatment would be an effective treatment of penile injury to prevent complications.

We report a case of type III hyperlipoproteinemia associated with xanthoma eruptivum. Xanthoma tuberosum, and xanthoma striatum palmare whose clinical symptoms have been improved by the treatment of gemfibrozil. A 31-year-old male patient visited our clinic for evaluation of multiple yellowish nodules on the elbows, multiple yellowish plaques on the buttocks and linear yellowish plaques along with the palmar creases on both palms. The blood chemistry showed an elevation of cholesterol and triglyceride. Lipoprotein electrophoresis showed broad betazone and plasma standing test showed turbid plasma. Lipoprotein ultracentrifugation showed that the ratio of VLDL cholesterol and plasma triglyceride was 0.38. According to the above findings, we diagnosed this patient as type III hyperlipoproteinemia. After 4 months of treatment with diet and gemfibrozil, the serum level of cholesterol and triglyceride were reduced to normal range. The skin lesions of both palms showed marked improvement but the skin lesions on elbows and buttocks were not much improved.

The Epstein-Barr virus(EBV) is known to play a causal role in oncogenesis and to be associated with endemic Burkitt's lymphomas, B cell lymphomas in immunocompromised patients, and nasopharyngeal carcinomas. More recently, EBV has also associated with Hodgkin's disease, B cell lymphomas in non-immunocompromised patients, and T-cell lymphomas. Twenty eight cases of a non-Hodgkin's lymphoma of gastrointestinal tract were investigated to determine both the immunophenotype by using immunohistochemical staining and the incidence of the EBV nuclear antigen by using the polymerase chain reaction. Twenty-four of the 28 cases(85.7%) were B-cell type, and 4 of the 28 cases(14.3%) are of T-cell type. The EBV nuclear antigen was detected in three of the 28 cases(10.7%), including two cases of B-cell lymphoma of the stomach and one case of T-cell lymphoma of the small bowel. The EBV nuclear antigen was more frequently found in malignant lymphomas arising in the intestine(1/4) than in stomach(2/16). EBV positivity (25%) in T-cell NHLs was rather higher than EBV positivity (8.3%) in B-cell NHLs. Further expanded evaluations on the role of EBV in the tumorigenesis of a gastrointestinal malignant lymphomas are necessary because the cases of gastrointestinal lymphomas examined were very limited.

BACKGROUND: The literature on variations of rib is limited. Very little has been written in the radiological journal of this country on the subject. It seemed of interest to investigate the nature and incidence of congenital variations in a series of routine chest roentgenograms. The topic of rib variations has not been covered extensively in the radiological journals in Korea. This has presented an opportunity to investigate the nature, type, shape and incidences of congenital rib variations in normal Korean adults from a series of routine roentgenograms. METHODS: Chest radiographs of 5,000 adults (,) who visited our hospital for a routine check-up or for employment physical examinations from January 1996 to September 1998, were consecutively reviewed. The sex distribution consisted of 2,827 male males and 2,173 females (ratio of 1.3:1) with the age range between 19 and 65 years (mean age: 34.6 years). The chest PAs was were analyzed for the presence, type, location, and shape of the rib variations (.) From this data, and we the incidence of each type of variations was calculated. RESULTS: Seventy-six of the 5000 adults (1.52%), 63 male (2.23%) and 13 female (0.6%), showed 88 cases of rib variation (Table 1). Bifid rib (n=35) was the The most common variation was the bifid rib (n=35), followed by hypoplasia of the rib (n=22), flaring of the rib (n=18), bridging of the ribs (n=7), cervical ribs (n=3), and fusion of between ribs (n=3) (Table 2). (New paragraph)Bifid The bifid rib (Table 1) was found most frequent in the right fourth rib (12/35, 34.3%), followed by the left fifth rib (6/35, 17.1%) and right third rib (6/35, 17.1%). Hypoplasia of the rib was common in first rib (20/22, 90.9%). Flaring of the rib was common at fourth rib (8/18. 44.4%, right and left combined) (,) and bridging between ribs was common between first and second rib (3/7, 42.9%). CONCLUSION: The percentage of incidence of rib variations in adults was 1.52%. Bifid rib was the most common variation, followed by hypoplasia, flaring, bridging, cervical rib, and fusion of ribs(,) in decreasing order.

Localized scleroderma is a disease of unknown origin and is characterized by circumscribed sclerotic skin changes. When occurring in a linear pattern, it is called linear scleroderma. 'En coup de sabre' is a subtype of linear scleroderma which is characterized by band-like, ivory-colored depressions on the frontoparietal scalp region. Several treatment modalities have been used. However, they have not been effective or safe. We report our experience of two patients with 'en coup de sabre' on the forehead, who were treated successfully with polymethylmethacrylate microspheres (PMMA-NewPlastic(R)).
