PURPOSE: Neuronal apoptotic events induced by aging and hypoxic/ischemic conditions is an important risk factor in neurodegenerative diseases such as ischemia stroke and Alzheimer's disease. The peel of Citrus sunki Hort. ex Tanaka has long been used as a traditional medicine, based on multiple biological activities including anti-oxidant, anti-inflammation, and anti-obesity. In the current study, we examined the actions of fermented C. sunki peel extract against cobalt chloride (CoCl2)-mediated hypoxic death in human neuroblastoma SH-SY5Y cells. METHODS: Cell viability was measured by trypan blue exclusion. Expression of apoptosis related proteins and release of cytochrome c were detected by western blot. Production of intracellular reactive oxygen species (ROS) and apoptotic morphology were examined using 2',7'-dichlorofluorescin diacetate (DCF-DA) and 4',6-diamidino-2-phenylindole (DAPI) staining. RESULTS: Exposure to CoCl2, a well-known mimetic agent of hypoxic/ischemic condition, resulted in neuronal cell death via caspase-3 dependent pathway. Extract of fermented C. sunki peel significantly rescued the CoCl2-induced neuronal toxicity with the cell viability and appearance of apoptotic morphology. Cytoprotection with fermented C. sunki peel extract was associated with a decrease in activities of caspase-3 and cleavage of poly (ADP ribose) polymerase (PARP). In addition, increase in the intracellular ROS and release of cytochrome c from mitochondria to the cytosol were inhibited by treatment with extract of fermented C. sunki peel. CONCLUSION: Based on these data, fermented C. sunki peel extract might have a protective effect against CoCl2-induced neuronal injury partly through generation of ROS and effectors involved in mitochondrial mediated apoptosis.

PURPOSE: The dried body of Scolopendra subspinipes mutilans has long been used as a traditional Korean medicinal food, but little is known about its mechanisms of action. In this study, we investigated the anti-inflammatory activities of Scolopendra subspinipes mutilans and possible mechanisms in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. METHODS: Cytotoxicity of Scolopendra subspinipes mutilans extract (SSME) was measured by MTT assay, anti-inflammatory activities were analyzed by nitric oxide (NO) production, the expression of inducible NO synthase (iNOS) and the mRNA level of pro-inflammatory cytokines such as interleukin-1β (IL-1β) and interleukin-6 (IL-6). Nuclear translocation of nuclear factor-kappa B (NF-κB) p65 subunit and degradation of inhibitory kappa B (IκB) were examined by western blot. RESULTS: SSME inhibited LPS-induced NO production and iNOS expression without cytotoxicity. Up-regulation of LPS-induced pro-inflammatory cytokines, IL-1β and IL-6 was dose dependently attenuated by SSME. Exposure of pyrrolidine dithiocarbamate, an NF-κB specific inhibitor, accelerated the inhibitory effects of SSME on NO production and iNOS expression in LPS-stimulated cells. Moreover, translocation of NF-κB from the cytosol to the nucleus and degradation of IκB were decreased by treatment with SSME in LPS-induced cells. CONCLUSION: These results suggest that the SSME might have the inhibitory effects on inflammation, partly through inhibition of the NF-κB signaling pathway.

PURPOSE: Neuroinflammation is mediated by activation of microglia implicated in the pathogenesis of neurodegenerative disorders such as Alzheimer's disease and Parkinson's disease. Inhibition of neuroinflammation may be an effective solution to treat these brain disorders. Petalonia binghamiae is known as a traditional food, based on multiple biological activities such as anti-oxidant and anti-obesity. In present study, the anti-neuroinflammatory potential of Petalonia binghamiae was investigated in LPS-stimulated BV2 microglial cells. METHODS: Cell viability was measured by MTT assay. Production of nitric oxide (NO) was examined using Griess reagent. Expression of inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2) was detected by Western blot analysis. Activation of nuclear factor κB (NF-κB) signaling was examined by nuclear translocation of NF-κB p65 subunit and phosphorylation of IκB. RESULTS: Extract of Petalonia binghamiae significantly inhibited LPS-stimulated NO production and iNOS/COX-2 protein expression in a dose-dependent manner without cytotoxicity. Pretreatment with Petalonia binghamiae suppressed LPS-induced NF-κB p65 nuclear translocation and phosphorylation of IκB. Co-treatment with Petalonia binghamiae and pyrrolidine duthiocarbamate (PDTC), an NF-κB inhibitor, reduced LPS-stimulated NO release compared to that in PB-treated or PDTC-treated cells. CONCLUSION: The present results indicate that extract of Petalonia binghamiae exerts anti-neuroinflammation activities, partly through inhibition of NF-κB signaling. These findings suggest that Petalonia binghamiae might have therapeutic potential in relation to neuroinflammation and neurodegenerative diseases.

Desmoid tumor is rare neoplasm originated from fibrous sheath or musculoaponeurotic structure. It is classified as benign tumor histologically, but clinically, it has malignant characteristics due to its infiltrative growth to adjacent organ and frequent local recurrence. Especially, mesenteric desmoid tumor shows poor prognosis because of its symptoms of pain, intestinal obstruction, ureter obstruction and fistula formation and high frequency of recurrence. We experienced a case of mesenteric desmoid tumor in a 64-year-old woman with a painless abdominal mass. Laparoscopic exploration was performed and 10 cm sized mesenteric mass was identified, which resected widely and the diagnosis was confirmed with desmoid tumor by pathologic report. We reviewed the feature of the mesenteric desmoid tumor, that is, pathophysiology, clinical presentations, diagnosis, treatment and prognosis.

A 63-year-old woman was referred to a breast surgeon with a breast mass discovered incidentally during follow-up study after colon cancer surgery. Invasive adenocarcinoma was revealed on core needle biopsy. Wide excision of the breast including the tumor was performed. On standard histological examination the tumor showed features of moderately differentiated adenocarcinoma. The immunohistochemistry study revealed positive results for cytokeratin (CK)20 and CDX2, but negative for CK7. These are typical characteristics for colon cancer. Considering her history of subtotal colectomy for sigmoid colon cancer, it is presumable that the mass in the breast was of colonic origin, and it was an extremely rare case of metastasis to the breast from primary colorectal neoplasm. Although the instance is rare, clinicians should keep the possibility of breast metastasis from colorectal cancer in mind for early and correct diagnosis.

Crohn's disease was originally described as a small bowel disorder and has been known to involve the large bowel in approximately 40% of all cases with or without concomitant ileal component. We describe two cases of Crohn's diseas of small intestine and colon with a summary of differential diagnosis with ulcerative colitis. Both cases were originally diagnosed and treated as ileal tuberculosis. Grossly, there were skip lesions in both cases with prominent pseudopolyps and ulcerations in colon. Also noted were typical serpentine lesions in ileum as well as in colon. Microscopically, transmural inflammation was confirmed and one case showed scattered noncaseating granulomas in the wall. Submucosal edema and fibrosis with thickening of the wall was not prominent in colon. Polymerase chain reaction performed on paraffin block for the demonstration of Mycobacterium tuberculosis in one case showed negative reaction.

PURPOSE: To assess the prognostic value of computed tomography (CT) in acute pancreatitis, initial CT examinations were classified into 5 grades in terms of the degree of disease severity and CT findings were correlated with clinical course, objective prognostic signs, and complications. MATERIALS AND METHODS: In 29 consecutive patients with acute pancreatitis, the CT examination and clinical course were reviewed without knowledge of each other finding. Both Ranson's prognostic signs and modified Glascow prognostic signs were used for evaluation of acute pancreatitis. RESULTS: Of the 29 patients, 25 patients recovered with medical treatment while 4 patients (14%) developed pseudocysts and the other 4 patients (14%) developed abscesses. CT findings of the acute pancreatitis are as follows; 10 patients (35%) in grade A with normal pancreas, 2 patients (7%) in grade B with pancreatic enlargement, 2 patients (7%) in grade C with intrinsic pancreatic abnormalities associated with haziness, 3 patients (10%) in grade D with single, ill-defined fluid collection, and 12 patients (41%) in grade E with extensive and two or multiple fluid collections or presence of gas in or adjacent to the pancreas. Correlation coefficient is 0.46 (p=0.012) between CT findings and Ranson's prognostic signs, 462 (p=0.0115) between CT findings and modified Glascow prognostic signs. CONCLUSION: CT gradings of acute pancreatitis may be useful in predicting clinical course.

PURPOSE: The purpose of this study was to describe factors affecting body image and sexual life for colorectal cancer patients with stoma. METHODS: A cross-sectional descriptive correlational study was applied to 102 ostomates from June to November in 2015 using self-report questionnaires: the Body image scale (BIS), and the Derogatis interview for sexual functioning self report (DISF-SR). RESULTS: The influencing factors for body image were ‘need for preoperative sexual education and sexual counseling’ (β=−.29, p=.003), and clinical stage II of colorectal cancer (β=−.26, p=.006). The influencing factor for sexual life was educational level (college education or higher) (β=.21, p=.02). CONCLUSION: The results of this study showed that colorectal cancer patients with stoma had a negative body image. The sexual counseling and education for ostomates should be approached by considering gender characteristics.
