The purpose of this study was to confirm the anti-tumor activity of an ethanol extract of Saussurea laniceps against pancreatic tumor and to isolate the active compound from S.laniceps extract. Treatment with S.laniceps extract and hispidulin inhibited proliferation of pancreatic cell lines, such as Capan-1, Capan-2, Panc-1 and S2-013 in a dose-dependent manner using the hollow fiber assay. Hispidulin showed typical hallmarks of apoptotic cell death a significant anti-tumor activity on Capan-2 cells at a dose of 100 mg/kg and 200 mg/kg. S.laniceps has potential cytotoxic and apoptotic effects on human pancreatic carcinoma cells. Its mechanism of action might be associated with the apoptotic cell death through DNA fragmentation.

The authors reviewed 50 patients of congenital dislocation of the hip who had surgical treatment at the Department of Orthopedic Surgery, Seoul National University Children's Hospital from October, 1985 to August, 1993. We investigated the contributing factors to coxa magna after surgical treatment and it's relationship to the avascular necrosis of femoral head, and observed the influnce of coxa magna on the development of the hip joint. Coxa magna was defined as a femoral head with the greatest diameter 15% greater than the opposite side. To assess the development of the acetabulum in the hips with coxa magna, radiographical horizontal and vertical parameters were measured preoperatively, and at postoperative 1 year, 2 year, and 3 year or more. Twenty-one of fifty hips had coxa manga. The incidence of coxa magna increased in patients who had open reduction at younger age(average 30 months), compared to older age(average 44 months). Neither femoral osteotomy nor pelvic osteotomy increased statistically the incidence of coxa magna. Avascular necrosis of femoral head did not necessarily resulted in coxa magna. There were not statistically significant differences in the coverage ratios of femoral head by the acetabulum between coxa magna positive and negative groups, because lateral acetabular growth accompanied in accordance with enlargement of femoral head in the majority of cases with coxa magna. Open reduction alone caused concomitant vertical overgrowth of ipsilateral hemi-pelvis with resultant pelvic tilt and leg length inequality(IHD>5mm, upto 2cm) in 6 of 10 cases. The patients, who had coxa magna with good radiological results by Severin's classification, underwent open reduction at younger age and had lesser enlargement of the femoral head, compared to those with fair or poor results.

Beta-fluoroethylacetate has been extensively used as the rodenticide in Korea. In some patients with acute poisoning, beta-fluoroethylacetate caused cerebellar dysfunction as a single and persistent neurologic sequela after a period of an acute neurological disorder which is characterized by mental deterioration, seizures, and respiratory failure. But there has been no report of pathological findings to explain neurological deficit. We tried to verify the histologic changes of the central nervous systems in beta-fluoroethylacetate poisoned rats. Silver staining(Gallyas) was used to evaluate the histology. In acute intoxication experiment with LD50(7mg/Kg), beta-fluoroethylacetate elicited acute onset of consciousness deterioration, generalized tonic-clonic seizures and large amplitude tremulous activity involving whole body with full recovery after 24 hours. There was no discernible pathologic change in CNS in acutely poisoned rats. However, when poisoned with sublethal dose(5mg/Kg) daily for five days, a moderate degree of nerve cell degeneration was found selectively in dentate nucleus, Purkinie cell layer, vestibulo-cochlear nucleus and striatum. This change was not seen in hippocampus, cerebral cortex or cerebellar cortex. These findings were well correlated with the previous reports of selective pathology in human 5-FU intoxication cases. Our preliminary results suggest that beta-fluoroethylacetate, a kind of cellular metabolism inhibitor may induce selective neuropathology mainly involving cerebellar output pathway in rats.

PURPOSE: To assess the clinical outcomes of cyclosporine treatment for noninfectious uveitis. METHODS: A retrospective review of medical records was completed for 182 noninfectious uveitis patients who were treated with cyclosporine between January 2001 and August 2010. Data was obtained relevant to demographic characteristics, anatomic classification, and laterality of uveitis, associated systemic disorder, dosage of cyclosporine and prednisolone, usage of other immunosuppressive drugs, visual acuity (VA), control of uveitic activity, and adverse effects during the cyclosporine use. RESULTS: Uveitic activity was controlled to a level of minimal inflammation in 89.0% and completely in 78.6% of patients by the median duration of 49 and 98 days, respectively. Prednisolone-sparing (dose < or =10 mg) control of inflammation equal to or less than the minimal activity was achieved in 75.3% of patients. VA was aggravated more than 0.2 logarithm of the minimum angle of resolution in 17.3% of eyes in spite of cyclosporine treatment for the mean follow-up of 698.4 days. Dose reduction and cessation of cyclosporine was required only in 3.3% and 9.3%, respectively, due to the intolerable toxicity, although 44.0% of patients experienced mild to moderate adverse effects. CONCLUSIONS: Cyclosporine combined with corticosteroids or other immunosuppressive drugs as needed is an effective treatment for noninfectious uveitis, thus minimizing the adverse effects of corticosteroids and other toxic drugs. However, careful monitoring for the toxicity of cyclosporine is needed, because a small group of patients cannot tolerate its toxicity.

Peyronie's disease is characterized by localized fibrosis in the tunica albuginea of the corpus cavernosum with no confirmed etiology. We report 2 cases of Peyronie's disease, in which surgical1y corrected with the dermal graft technique. One patient is performed with the penile prosthesis be. cause of sexual impotence after correction of penile curvature.
