We preset a rare case of traumatic rupture of the iliacus muscle associated with paralysis of the femoral nerve. It occurred in a healthy 17 year old boy immediately after a fall on his back during the Taekwondo practice. The clinical picture is characterized by pain in the groin, a tender mass in the iliac fossa, flexion contracture of the hip, and a complete paralysis of the ipsilateral femoral nerve. This condition rarely occurs in individuals without bleeding tendency

MR images of seven patients with histologically documented synovial sarcoma were reviewed to find the suggestive or pathognomonic findings of the disease. MR appearance of the tumor was inhomogeneous, multiseptated mass with various degree of internal septation and infiltrative tumor margin. The signal intensity of the mass was slightly hyperintense relative to muscle on T1-weighted image and hyperintense relative to subcutaneous fatty tissue on T2-weighted image.

Cyanide intoxication results in severe metabolic acidosis and catastrophic prognosis with conventional treatment. Indications of extracorporeal membrane oxygenation (ECMO) and continuous renal replacement therapy (CRRT) are expanding to poisoning cases. A 50-year-old male patient arrived in the emergency room due to mental change after ingestion of cyanide as a suicide attempt 30 minutes prior. He was comatose, and brain stem reflexes were absent. Initial laboratory analysis demonstrated severe metabolic acidosis with increased lactic acid of 25 mM/L. Shock and acidosis were not corrected despite a large amount of fluid resuscitation with highdose norepinephrine and continuous renal replacement therapy. We decided to apply ECMO and CRRT to allow time for stabilization of hemodynamic status. After administration of antidote infusion, although the patient had the potential to progress to brain death status, vital signs were improved with correction of acidosis. We considered the evaluation for organ donation. We report a male patient who showed typical cyanide intoxication as lethal metabolic acidosis and cardiac impairment, and the patient recovered after antidote administration during vital organ support through ECMO and CRRT.

This study was undertaken to investigate the characterization and distribution patterns of MHC class II positive dendritic cells[DCs] and ED2 positive tissue macrophages throughout the estrous cycle and during pregnancy in the rat ovary. The immunohistochemical characterization of the cells was carried out using the monoclonal antibodies OX6 and ED2 in cryostat-cut sections. DCs were distributed in the theca cell layer of the growing and mature follicles,stroma and corpus luteum. Tissue macrophages were distributed in the theca externa of the growing and mature follicles, stroma and corpus luteum but they were smaller in number than DCs. None of DC and tissue macrophage was found in the ovum, granulosa layer and follicular cavity of the ovarian follicle. However, DCs and tissue macrophages were present in the granulosa layer and follicular cavity in the atretic follicles. Degenerating corpus luteum contained a vast number of OX6 positive cells. On the contrary, fewer tissue macrophages were founcl in the degenerating corpus luteum. More macrophages tended to be observed in the former follicular cavity and theca lutein cell layer than in the granulosa lutein cell layer of the corpus luteum. In stroma,DCs and tissue macrophages were more frequently found around the blood vessels than in the other region, however, DCs were relatively greater in number than tissue macrophages. There was no estrous cycle and pregnancy dependent variation in the numbers and distribution patterns of DCs and tissue macrophages. In conclusion, the rat ovary contains rich networks of MHC class II positive dendritic cells and ED2 positive tissue macrophages. These findings suggest the existence of a well-developed system of immunological surveillance in the rat ovary. The results of this study have potentially important implications for the understanding not only of the ovarian immune system and the pathogenesis of various ovarian diseases but also of various physiologic functions of the ovary.

This study was performed to investigate the effects of Staphylococcal enterotoxin B (SEB) on dendritic cells (DCs) and other immune cells in the major lymphoid organs. A single dose of SEB (25 microgram/kg) was administered to BALB/c mice by intraperitoneal injection. After the mice were sacrificed in groups of three at 2 h, 6 h, 1 day, 2 days, 3 days, 1 week and 2 weeks, the spleen, lymph node and thymus were removed. The immunocytochemical characterization of the cells was carried out using various monoclonal antibodies in cryostat-cut sections. We demonstrated in this study the distribution patterns of DCs and their major costimulatory and adhesive molecules in the murine spleen, lymph node and thymus after SEB administration. We obtained the evidence for maturation of DCs in vivo in response to SEB. DCs were found in increased number in the periarterial lymphatitc sheath (PALS) of spleen, paracortex of lymph nodes and thymic medulla. CD86, ICAM-1 and MHC class II molecules were upregulated on the activated and matured DCs after SEB injection. The most salient feature of the present study was the differential expression pattern of the costimulatory and adhesive molecules on the activated DCs. In addition to DCs, T cells expressing T cell receptor Vbeta8 were increased in number after SEB treatment. In conclusion, SEB exhibited a potent and effective stimulative effect on DCs in vivo.
