GTPrS-dependent phospholipase D activity in human neutrophils was investigated using exogenous phospholipid as a substrate. Both cytosolic and membrane- associated phospholipase D activities were identified. The previously described 50 kDa cytosolic activating factor was resolved chromatographically from the cytosolic phospholipase D. Using exogenous phospholipid as substrate along with chromatographically resolved 50 kDa factor and recombinant ADP-ribosylation factor 1, plasma membrane was required for activity, indicating that the activity which was previously seen using endogenous phospholipid substrate was due to a phospholipase D located in the plasma membrane. In addition, ADP-ribosylation factor and the 50 kDa factor activated synergistically. Using neutrophil plasma membranes, a third regulator of neutrophil membrane phospholipase D was identified from bovine brain cytosol. This factor was resolved from ADP-ribosylation factor and Rho A by successive column chromatographies. The brain factor showed a synergistic effect with the 50 kDa neutrophil activator but an additive effect with recombinant ADP- ribosylation factor. Whether or not ADP-ribosylation factor or the brain factor were present, high activities were seen only when the 50 kDa factor was present, indicating that the 50 kDa cytosolic factor is a major activating factor for the neutrophil plasma membrane phospholipase D.

Ehlers-Danlos Syndrome(EDS) is an inherited disorder of the connective tissue disease that is usually transmitted as autosomal dominant trait. The defect in the biogenesis of collagen results in varying degree of skin hyperextensibility, joint hypermobility, skin fragility and bruising. There have been several reports of cardiac or great vessel abnormalities in patients with the EDS. A 45-year-old Woman was admitted to Maryknoll hospital because of orthopnea, palpitation and epigastric discomfort. Physical examination reveals multiple variable sized bruises and increased hyperelasticity on skin, and hypermobile joint in knee and proximal interphalanges of both hands. Mitral valvular prolapse and atrial septal defect were detected by echocardiography. We report a case of EDS accompanied by mitral valvular prolapse and ostium secundum atral septal defect with brief review of literature.

PURPOSE: The purpose of this study was to review and reevaluate the well-known ultrasonographic characteristics of cysts of the thyroglossal duct. MATERIALS AND METHODS: We retrospectively reviewed the ultrasonographic findings in 31 patients with pathologically proven cysts of the thyroglossal duct. Assessment involved the following variables: relationship to the hyoid bone, location, shape, size, margin, internal echogenicity, the presence of septa, solid component, and thickness of the cystic wall. The echogenicity of cystic contents was evaluated in 23 cysts for which surgical or aspiration biopsy reports were available. RESULTS: Cysts were closely attached to the hyoid bone in 30 cases (97%). Their location was infrahyoid in 14 cases, hyoid in 11, and suprahyoid in six; and midline in 18, both midline and off-midline in nine, and off-midline in four. A triangular shape was seen in 15 cases, a round or oval shape in 12, and a lobulated shape in three. Their diameter varied from 1 to 3.8 (mean, 2) cm, while internal echogenicity was hypoechoic in 12 cases, anechoic in ten, and isoechoic in nine. Septations were noted in six cases, and a solid component in two. The cystic wall was less than 1mm thick in 17 cases, even and greater than 1mm in eight, and uneven and greater than 1mm in six. Among 23 cases, the cystic contents were mucous in 18, serous in three, and purulent in two. The echogenicity of cysts with mucous content varied, while serous or purolent cysts were isoechoic. CONCLUSION: The characteristic sonographic finding of cyst of the thyroglossal duct is a centrally located triangular neck cyst, closely related to the hyoid bone.

Development of a therapy providing protection from, or reversing gentamicin-sulfate (GS)-induced oxidative stress and nephrotoxicity would be of great clinical significance. The present study was designed to investigate the protective effects of Houttuynia cordata Thunb. (HC) against gentamicin sulfate-induced renal damage in rats. Twenty-eight Sprague-Dawley rats were divided into 4 equal groups as follows: group 1, control; group 2, GS 100 mg/kg/d, intraperitoneal (i.p.) injection; group 3, GS 100 mg/kg/d, i.p. + HC 500 mg/kg/d, oral; and group 4, GS 100 mg/kg/d i.p. + HC 1000 mg/kg/d, oral administration). Treatments were administered once daily for 12 d. After 12 d, biochemical and histopathological analyses were conducted to evaluate oxidative stress and renal nephrotoxicity. Serum levels of creatinine, malondialdehyde (MDA), and blood urea nitrogen (BUN), together with renal levels of MDA, glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT) were quantified to evaluate antioxidant activity. Animals treated with GS alone showed a significant increase in serum levels of creatinine, BUN, and MDA, with decreased renal levels of GSH, SOD, and CAT. Treatment of rats with HC showed significant improvement in renal function, presumably as a result of decreased biochemical indices and oxidative stress parameters associated with GS-induced nephrotoxicity. Histopathological examination of the rat kidneys confirmed these observations. Therefore, the novel natural antioxidant HC may protect against GS-induced nephrotoxicity and oxidative stress in rats.

Zearalenone (ZEN) is a non-steroidal estrogenic mycotoxin produced by several species of Fusarium that are found in cereals and agricultural products. ZEN has been implicated in mycotoxicosis in farm animals and in humans. The toxic effects of ZEN are well known, but the ability of an alkaline Comet assay to assess ZEN-induced oxidative DNA damage in Chang liver cells has not been established. The first aim of this study was to evaluate the Comet assay for the determination of cytotoxicity and extent of DNA damage induced by ZEN toxin, and the second aim was to investigate the ability of N-acetylcysteine amide (NACA) to protect cells from ZEN-induced toxicity. In the Comet assay, DNA damage was assessed by quantifying the tail extent moment (TEM; arbitrary unit) and tail length (TL; arbitrary unit), which are used as indicators of DNA strand breaks in SCGE. The cytotoxic effects of ZEN in Chang liver cells were mediated by inhibition of cell proliferation and induction of oxidative DNA damage. Increasing the concentration of ZEN increased the extent of DNA damage. The extent of DNA migration, and percentage of cells with tails were significantly increased in a concentration-dependent manner following treatment with ZEN toxin (p < 0.05). Treatment with a low concentration of ZEN toxin (25 microM) induced a relatively low level of DNA damage, compared to treatment of cells with a high concentration of ZEN toxin (250 microM). Oxidative DNA damage appeared to be a key determinant of ZEN-induced toxicity in Chang liver cells. Significant reductions in cytolethality and oxidative DNA damage were observed when cells were pretreated with NACA prior to exposure to any concentration of ZEN. Our data suggest that ZEN induces DNA damage in Chang liver cells, and that the antioxidant activity of NACA may contribute to the reduction of ZEN-induced DNA damage and cytotoxicity via elimination of oxidative stress.

BACKGROUND: The expressions of thymidylate synthase (TS), E2F-1, pRb, and p53 are correlated with DNA synthesis. The significance of their expressions is still controversial for predicting the outcome of 5-fluorouracil (5-FU) therapy in the patients with advanced gastric carcinoma. Furthermore, their prognostic value in the metastatic lesions of gastric carcinoma has not yet been confirmed. METHODS: To ascertain their prognostic value, we immunohistochemically analyzed the expressions of TS, E2F-1, pRb, and p53 in the primary tumors and the related metastatic lymph nodes, and we then compared the survival between the high and low expression group of each protein. Ninety four patients with advanced gastric carcinoma who were treated by complete resection and adjuvant 5-FU chemotherapy were analyzed. RESULTS: The TS expression in primary tumors was significantly correlated with that of E2F-1. The expression of these genes showed no significant difference between the primary tumors and the metastatic lymph nodes except for E2F-1, which was significantly higher in the lymph node metastasis than in the primary tumors. After complete resection and 5-FU-based adjuvant chemotherapy, patients with a high TS expression in the primary tumors showed a longer survival than those patients having primary tumors with a low TS expression (p=0.0392). CONCLUSION: A high TS expression in the primary tumors may be related to a better outcome for advanced gastric cancer patients who were treated with 5-FU chemotherapy after curative resection.

Objective: To investigate the effects of long-acting injectable 3-monthly paliperidone palmitate on the clinical and social functioning of patients with schizophrenia. Methods: This study enrolled patients with schizophrenia receiving long-acting injectable 1-monthly paliperidone palmitate for at least 4 months and who subsequently received 3-monthly paliperidone palmitate. Accordingly, 418 patients were followed up for 24 weeks. Their clinical symptoms and social functioning were measured using the Clinical Global Impression-Severity of Illness and Personal and Social Performance scales. Results: The Personal and Social Performance total score was significantly higher after 3-monthly paliperidone palmitate treatment than at baseline (baseline vs. week 24: 54.3 ± 18.0 vs. 61.0 ± 14.5 [mean ± standard deviation]; p ＜ 0.001; Wilcoxon signed-rank test); the proportion of patients in the mildly ill group (scores 71−100) also increased significantly (baseline vs. week 24: 16.5% vs. 20.6%; p＜ 0.001; McNemar-Bowker test). The mean Clinical Global Impression-Severity of Illness score decreased significantly (baseline vs. week 24: 3.7 ± 1.0 vs. 3.4 ± 0.9; p＜ 0.001; Wilcoxon signed-rank test), as did the proportion of patients in the severely ill group (baseline vs. week 24: 4.1% vs. 2.1%; p ＜ 0.001; McNemar-Bowker test). Conclusion Continuous 3-monthly paliperidone palmitate treatment significantly enhances the personal and social performance of patients with schizophrenia and reduces the proportion of those with severe illness. These findings suggest that long-acting injectable antipsychotic administration at intervals longer than 1 month might improve the social functioning of and promote return to activities of daily living in patients with schizophrenia.

Intraductal papillary mucinous tumor (IPMT) of the pancreas is a recently understood unique clinicopathologic disease entity comprising approximately 1% of all exocrine pancreatic tumors and 11% of cystic neoplasms of pancreas. It has been reported worldwide, mostly in Japan. It is generally characterized by recurrent pancreatitis, mucin oozing from the papilla of Vater, and dilated pancreatic duct with intraductal filling defects. Microscopically, the mucin-producing columnar epithelium forms papillary proliferation into the dilated pancreatic duct and this feature differentiates IPMT of the pancreas from the more common mucinous cystic neoplasms of the pancreas which usually do not communicate with the pancreatic duct. On the other hand, mucin-hypersecreting bile duct tumors have been rarely reported in the English literature. We herein present the first case of mucin-hypersecreting bile duct tumor combied with IPMT of the pancreas with a review of the related literature.

Background/Aims: Little is known about the clinical course of hepatitis B virus (HBV)-infected patients undergoing anti-tumor necrosis factor α (TNF-α) therapy for inflammatory bowel disease (IBD). We aimed to investigate the clinical course of HBV infection and IBD and to analyze liver dysfunction risks in patients undergoing anti-TNF-α therapy. Methods: This retrospective multinational study involved multiple centers in Korea, China, Tai-wan, and Japan. We enrolled IBD patients with chronic or resolved HBV infection, who received anti-TNF-α therapy. The patients’ medical records were reviewed, and data were collected using a web-based case report form. Results: Overall, 191 patients (77 ulcerative colitis and 114 Crohn’s disease) were included, 28.3% of whom received prophylactic antivirals. During a median follow-up duration of 32.4 months, 7.3% of patients experienced liver dysfunction due to HBV reactivation. Among patients with chronic HBV infection, the proportion experiencing liver dysfunction was significantly higher in the non-prophylaxis group (26% vs 8%, p=0.02). Liver dysfunction occurred in one patient with resolved HBV infection. Antiviral prophylaxis was independently associated with an 84% reduction in liver dysfunction risk in patients with chronic HBV infection (odds ratio, 0.16; 95% confidence interval, 0.04 to 0.66; p=0.01). The clinical course of IBD was not associated with liver dysfunction or the administration of antiviral prophylaxis. Conclusions Liver dysfunction due to HBV reactivation can occur in HBV-infected IBD patients treated with anti-TNF-α agents. Careful monitoring is needed in these patients, and antivirals should be administered, especially to those with chronic HBV infection.
