High output heart failure due to congenital arteriovenous fistula is a rare disease and is difficult to treat. A 27 year old man, suffering from dyspnea, palpitation, lower extremity edema, and abdominal distension admitted May, 1987. At admission there were continuous thrill and bruit at left supraclavicular and infraclavicular area. The heart sound was irregular and rapid, and grade IV/VI pansystolic murmur was audible at the apex. Chest PA showed marked cardiomegaly with pleural effusion and notching at superior aspect of left 2nd rib. Selective left subclavian artery angiogram showed extensive congenital arteriovenous fistula at the area of left subclavian artery and its branches. After setrial feeding artery embolization and palliative operation, the fistula size decreased much with clinical improvement.

PURPOSE: To evaluate the antiproliferative and antifibrotic effects of alpha-tocotrienols in primary cultured orbital fibroblasts from thyroid-associated ophthalmopathy (TAO) patients. METHODS: Orbital fibroblasts were cultured (5 eyes from TAO patients, 5 eyes from normal patients) and classified into a control group, alpha-tocotrienol group and alpha-tocopherol group. The cell viability was measured using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. The proliferation of orbital fibroblasts was measured using the Click-iT(TM) assay. The collagen production of the control and alpha-tocotrienol groups was measured using a hydroxyproline assay. RESULTS: The alpha-tocotrienol and alpha-tocopherol groups showed no cytotoxicity up to 150 microm in orbital fibroblasts from TAO and normal patients. The proliferation of orbital fibroblasts from TAO and normal patients was significantly inhibited with alpha-tocotrienol at 80 microm and 120 microm. The collagen production of orbital fibroblasts from TAO patients was significantly inhibited with alpha-tocotrienol at 120 microm. CONCLUSIONS: The results from the present study indicate that non-toxic concentrations of alpha-tocotrienol have significant antiproliferative and antifibrotic effects on orbital fibroblasts from TAO patients.

Rhabdomyosarcoma originating from the chest wall is a rare malignant tumor in children and was considered to be guarded in prognosis previously. However, recent advances in multidisciplinary treatment of rhabdomyosarcoma in children have improved the disease free survival rate. Authors report a case of alveolar rhabdomyosarcoma, stage III, originating from the chest wall who is surviving free of disease for 15 months with aggressive chemotherapy and radiotherapy.

Direct exposure of renal tubular brush-border membranes (BBM) to free cadmium (Cd) causes a reduction in phosphate (Pi) transport capacity. Biochemical mechanism of this reduction was investigated in the present study. Renal proximal tubular brush-border membrane vesicles (BBMV) were isolated from rabbit kidney outer cortex by Mg precipitation method. Vesicles were exposed to 50~200 muM CdCl2 for 30 min, then the phosphate transporter activity was determined. The range of Cd concentration employed in this study was comparable to that of the unbound Cd documented in renal cortical tissues of Cd-exposed animals at the time of onset of renal dysfunction. The rate of sodium-dependent phosphate transport (Na+-Pi cotransport) by BBMV was determined by 32P-labeled inorganic phosphate uptake, and the number of Na+/-Pi cotransporters in the BBM was assessed by Pi-protectable 14C-labeled phosphonoformic acid ((14C)PFA) binding. The exposure of BBMV to Cd decreased the Na+-Pi cotransport activity in proportion to the Cd concentration in the preincubation medium, but it showed no apparent effect on the Pi-protectable PFA binding. These results indicate that an interaction of renal BBM with free Cd induces a reduction in Na+-Pi cotransport activity without altering the carrier density in the membrane. This, in turn, suggest that the suppression of phosphate transport capacity (Vmax) observed in Cd-treated renal BBM is due to a reduction in Na+-Pi translocation by existing carriers, possibly by Cd-induced fall in membrane fluidity.

Mouse embryonic stem (mES) cells are capable of undergoing chondrogenesis in vitro. To enhance this process, the human SOX9 (hSOX9) cDNA was delivered into mES cells and the clones overexpressing hSOX9 (denoted as mES-hSOX9 cells) were verified by Western blot analysis. The transcripts of collagen IIA (a juvenile form), aggrecan and Pax1 were expressed in mES-hSOX9 cells grown on feeder layers, suggesting the immediate effect of exogenous SOX9 on chondrogenesis. However, SOX9 overexpression did not affect the cell cycle distribution in undifferentiated mES cells. Upon differentiation, collagen IIB (an adult form) was detected in day 3 immature embryoid bodies. In addition, the overexpression of exogenous SOX9 significantly induced transcriptional activity driven by SOX9 binding site. Taken together, we for the first time demonstrated that constitutive overexpression of exogenous SOX9 in undifferentiated mES cells might have dual potentials to induce both chondrogenic commitment and growth capacity in the undifferentiated status.

Otolaryngologic symptoms and findings are often the first manifestations of post-transplant lymphoproliferative disorder (PTLD) in children. We report a case of lymphoproliferative disorder which occurring in the epiglottis and aryepiglottic fold of a post-liver transplant, 28-month-old girl. Inspiratory stridor and mild respiratory distress were presented 7 months after the transplantation. Bronchoscopy revealed swelling of the epiglottis, multiple nodular lesions in the arytenoid and the pharyngeal wall, and collapse of the false vocal cord due to a redundant nodular mass during inspiration. Microscopic examination showed polymorphic, polyclonal small lymphoid aggregates, which were dominantly stained by monoclonal antibody to CD20. In this case, PTLD was associated with Epstein-Barr virus (EBV) infection. The patient was treated successfully by the surgical excision of the obstructing redundant mass in the arytenoids, dose reduction of immunosuppressive drugs and the administration of an antiviral agent. A diagnosis of PTLD should be considered in transplanted children who later develop upper airway obstruction.

BACKGROUND: Curcumin has been reported to have anti-inflammatory, antioxidant, antiviral, antifungal, antitumor, and antinociceptive activity when administered systemically. We investigated the analgesic efficacy of intrathecal curcumin in a rat model of inflammatory pain. METHODS: Male Sprague Dawley rats were prepared for intrathecal catheterization. Pain was evoked by injection of formalin solution (5%, 50 microl) into the hind paw. Curcumin doses of 62.5, 125, 250, and 500 microg were delivered through an intrathecal catheter to examine the flinching responses. The ED50 values (half-maximal effective dose) with 95% confidence intervals of curcumin for both phases of the formalin test were calculated from the dose-response lines fitted by least-squares linear regression on a log scale. RESULTS: In rats with intrathecal administration of curcumin, the flinching responses were significantly decreased in both phases. The slope of the regression line was significantly different from zero only in phase 2, and the ED50 value (95% confidence interval) of curcumin was 511.4 microg (23.5-1126.5). There was no apparent abnormal behavior following the administration of curcumin. CONCLUSIONS: Intrathecal administration of curcumin decreased inflammatory pain in rats, and further investigation to elucidate the precise mechanism of spinal action of curcumin is warranted.
