The aims of study presented here were to determine dose-dependent effects of UVB irradiation on CHS reaction and comparative effects of VVB on the induction and elicitation in guinea pigs. Pre-induction exposure to either suberythemal or supraerythemal doses of UVB resulted in suppreasion of CHS (53.47% & 57.64%) campared to positive control (79. 86%) However, suberythemal doses of UVB generated a more potent suppression than supraerythemal doses. Pre-elicitation exposure to suberythemal doses of UVB on the elicitation sites and adjacent to elicitation sites resulted in suppressed CHS reactions in both groups (60.4zg & 56.25p,). When the reaction by UVB was eliminated from the cutaneous reaction elicited in guinea pigs sensitized to DNCB, by UVB irradiation on the adjacent to elicitation sites, generated a more potent suppression than that UVB was directly irradiated on the elicitation sites.

Primary spinal glioblastoma multiforme is very rare, especially in childhood. 13-year-old boy was admitted to our neurosurgical department because of paraparesis, sensory loss below T10 and sphincter disturbance. Thoracic myelogram showed complete obstruction at T10 level and total laminectomy with partial removal of the intramedullary cord tumor mass was performed under the impression of spinal cord tumor. Postoperatively, his symptoms and signs unchanged. Pathological diagnosis was intramedullary glioblastoma multiforme involving thoracic cord.

BACKGROUND: Previous studies have demonstrated that enalapril or lovastatin seems to ameliorate the renal injury in several animal models with glomerulonephritis. The aim of this study was to examine whether enalapril or lovastatin was still beneficial in tubulointerstitial injury induced by protein-overload proteinuria in rats. METHODS: Enalapril(200mg/L in the drinking water) or lovastatin(16mg/kg, subcutaneously) was administered to uninephrectomized rats which received a daily intraperitoneal injections of bovine serum albumin(BSA, 1/100g body weight)(each n=6). Six rats were served as normal control. After 2 weeks, renal cortical pathologic findings, including immunohistochemistry for macrophage were examined and renal cortical osteopontin, MCP-1, endothelin-1, TGF-beta and procollagen alpha1(I) mRNA expression were examined by Northern blot analysis. RESULTS: Renal cortex in rats with protein-overload proteinuria showed infiltration of inflammatory cells including macrophages, tubular dilatation and atrophy. Renal cortical mRNA expression of osteopontin, MCP-1 and endothelin-1 were increased in rats with protein-overload proteinuria. There were no changes in TGF-beta and procollagen alpha1(I) mRNA expression. Enalapril decreased the macrophage infiltration significantly and inhibited the mRNA expression of osteopontin, MCP-1 and endothelin-1. However, lovastatin had no significant effects on the macrophage infiltration and cortical mRNA expression. CONCLUSION: Enalapril showed beneficial effects in tubulointerstitial injury induced by protein-overload proteiuria in rats by inhibition of macrophage infiltration and the cortical mRNA expression of osteopontin, MCP-1 and endothelin-1. However, lovastatin had no significant effects.

The Fanconi syndrome is a complex tubulopathy, which is characterized by urinary hyperexcretion of amino acids of all classes, phosphate, glucose, bicarbonate, calkium, potassium, and otherions, and proteins with molecular weights under 50,000 daltons. This metabolic disease leads to hypophospatemia, hypokalemia, growth failure, metabolic acidasis, and rickets/osteomalacia. Fanconi syndrome may be inherited or acqulred. Most cases of adult Fanconi syndrome are acquired, and the acquired syndrome is associated with thermal burns, exposure to heavy metals or drugs, vitmnin D deficiency, renal transplantation, or light chain deposition. The most common cause of adult Fanconi syndrome is multiple myeloma. We ribe here a case of adult Fanconi syndrome and osteomalacia associated with x-light chain monoclonal gammopathy. A 47-year-old woman presented with multiple bane pain and proximal muscle weakness for 2 years. Laboratory findmgs showed hypophosphatemia, mild hypocalcemia, marked elevation of serum alkaline phosphatase, metabolic acidosis, low 25-OH- vitamm D level and secondary hyperparathyroidism. Urinary excretion of protein, uric acid, phosphate, and glucose was mcreased, and tubular reabsorption of phosphate was decreased to 50%. Protein immunofixation electrophoresis of serum and urine showed x-light chain type monoclonal gammopathy. Bone marrow examination was normal except moderate elevation of plasma cell component(8.8%). The skeletal radiography showed fractures of both lower ribs and pseudofracture in right femoral lesser trochanter. We treated the patient with calcium, 1.25-(OH)2-vitamin D, phosphorus, bicarbonate, and potassium, and her clinical symptoms were gradually relieved.

Aspergillus Infection is a major cause of mortality in individuals with depressed cell-mediated immunity. Despite therapy with intravenous amphotericin B and oral antifungal agents, high mortality has been reported among heart transplant recipients. We experienced two cases of pulmonary aspergillosis among 15 cases of heart transplantation cases. Both cases were similiar in terms of age, time of diagnosis, diagnosis, and medication. Percutaneous needle aspiration biopsy revealed Aspergillus fumigatus in both cases. The first case showed multiple aspergilloma on both lung fields and were treated by IV Amphotericin B and oral itraconazole. After completion of treatment, the lesion completely disappeared and he has been followed up for more than one year in his good condition. The second case showed a single nodule on his right lower lung field and were treated by both medication and surgery. The patient recovered well and had been doing well until 4th postoperative month when he developed humoral rejection and expired.

BACKGROUND: Monocyte chemoattractant protein-1 (MCP-1) and reactive oxygen species (ROS) play an important role during glomerular inflammation. We investigated the effect of aspirin metabolite, salicylate on the pro-inflammatory cytokine-induced MCP-1 expression and lysophosphatidylcholine -induced intracellular ROS formation in human mesangial cells. METHODS: Cells were pretreated with salicylate, and then stimulated with tumor necrosis factor-alpha (TNF-alpha) or interleukin-1beta (IL-1beta). The expression of MCP-1 mRNA and MCP-1 protein were measured by Northern blot analysis and enzyme-linked immunosorbent assay, respectively. Nuclear factor-kappa B (NF-kappaB) activity was measured by electrophoretic mobility shift assay. Degradation of Ikappa B-alpha was assessed by Western blot analysis. Intracellular ROS production was monitored by flow cytometry using 2'7'-dichlorofluorescin diacetate. RESULTS: Salicylate inhibited the TNF-alpha- or IL-1beta- induced MCP-1 mRNA expression in a dose dependent manner (1-20 mM) and also suppressed the MCP-1 protein expression. Its effect was not attributable to de novo synthesis of intermediary proteins. Salicylate inhibited the TNF-alpha- or IL-1beta-induced NF-kappa B binding activity and also suppressed the TNF-alpha-induced Ikappa B-alpha degradation. Low concentration of salicylate (0.01-1 mM) suppressed the lysophosphatidylcholine-induced ROS formation. CONCLUSION: Milimolar concentration of salicylate inhibited the MCP-1 expression at least in part, via suppression of NF-kappaB by reducing the degradation of Ikappa B-alpha. On the other hand, lower concentration of salicylate could suppress the lysophosphatidylcholine-induced intracellular ROS formation.

Paradoxical embolism is a kind of stroke caused by embolism of thrombus of venous origin through a lateral opening in the heart, such as a patent foramen ovale (PFO). Although the most frequent manifestation of paradoxical embolism is cryptogenic stroke, noncerebral paradoxical embolism is also associated with PFO. We experienced a case of cryptogenic renal infarction in a previously healthy 70-year-old man. He had no cardiac thrombus on transthoracic echocardiography and electrocardiogram revealed a normal sinus rhythm. Because it was cryptogenic renal infarction, we performed transesophageal echocardiography with microbubble test. Microbubble test using agitated saline proved the presence of right-to-left shunt and patent foramen ovale was diagnosed. We also performed lower leg doppler ultrasonogram, but there was no evidence of deep vein thrombosis. Although only the presence of a right-to-left shunt is not enough to establish the diagnosis of paradoxical embolism, it is uncommon for the source of the embolism to be identified. In this case, we concluded that paradoxical embolism is the cause of renal embolism. We report paradoxical renal embolism through PFO with review of relevant literatures.

Pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals is a rare and complex lesion in which great morphologic variability exists regarding the sources of pulmonary blood flow. We report a case of this disease with no true central pulmonary arteries in a 9-month-old-boy successfully treated by one-stage complete unifocalization and repair from a midline sternotomy approach.
