A 5 years old gelding (Thoroughbred, Equus caballus) had shown severe abdominal pain, colic, after overeating of hay in the feed storage. following through treatment, it subsequently died. Grossly, the large colon was impacted with firm mass of food and congestion of blood vessel in the intestinal wall. There were mild peritonitis and pleuropneumonia. This case demonstrates typical large colon impaction with hard consistence ingesta due to improper management of horse.

This study was performed to observe intestinal patholoay ill early Infection by Centrocestus crnlctus. The flukes were in the lowermost part of the intfrvillous space of the duodenum and jejunum from 1 day to 7 days postinfection (PI). Thr stroma of villi around the young fluke was edematous and infiltrated by inflanlrllatory knells Luch as Iymphocytes, plasma cells and eosinophils. The crypt became mildly llyperplastic and villi were moderately atrophied at 4 days Pl. The intestinal lesion produced was confillrd to the areas around the fluke. The pathologic findings were not significarltly different between 1,000 and 5,000 metacercariae infection groups. It is suggested that the lesion should be produced by mechanical destruction of the fluke on the enteroepithelial cells.

Background: Gastro-entero-pancreatic neuroendocrine neoplasms (GEP-NEN) are relatively rare tumors, not equally distributed in gastro-intestinal system. In 2010, a revised version of the WHO classification of GEP-NENs was published. This study reports for the first time the distribution and characteristics of GEP-NEN in a Lebanese population. Materials and Methods: This descriptive retrospective study concerns all the digestive neuroendocrine tumors with their characteristics diagnosed in $H\hat{o}tel$ Dieu de France in Beirut, Lebanon from 2001 to 2012, all the pathology reports being reanalyzed according to the latest WHO 2010 classification. The characteristics and features of GEP-NEN analyzed in this study were age, gender, grade and site. Results: A total of 89 GEP-NENs were diagnosed, representing 28.2% of all neuroendocrine tumors. The mean age of GEP-NEN patients was 58.7 years and the M/F sex ratio was 1.2. The primary localization was as follows: 21.3%(19) pancreatic, 18% (16) gastric, 15.7% (14) duodenal, 11.2% (10) appendix, 10.1% (9) intestinal, 10.1% (9) colorectal (7.9% colonic and 2.2% rectal), 5.6% (4) hepatic, 2.2% (2) ampulla, 1.1% (1) esophageal and 7.9%(5) NOS digestive (metastatic with unknown primary). Of the 89 patients with GEP-NEN, 56.2% (50) were diagnosed as grade I, 11.2% (10) as grade II, 20.2% (18) as grade III and 12.4% (11) were considered as mixed adeno-neuroendocrine carcinomas (MANEC). Conclusions: This study, one of the rare examples based on the 2010 WHO classification of neuroendocrine tumors in the literature, indicates that in the Lebanese population, all duodenal and appendicular tumors are G1 and the majority of MANEC tumors are gastric and pancreatic tumors. Moreover, more duodenal tumors and fewer rectal tumors were encountered in our study compared to European reports.

Although the incidence of tuberculosis has been reduced recently because of the advance of anti-tuberculosis chemotherapy, improvements of public health, and early diagnosis, it is still high in developing countries. Intestinal tuberculosis can occur at any age, but young adults and female are more affected. Early diagnosis of childhood intestinal tuberculosis is difficult, largely because of vague symptoms and nonspecific signs. Recently, tuberculosis of the larynx combined with pulmonary tuberculosis has become quite a rare disease since anti-tuberculous chemotherapy and preventive activities are prevalent. Laryngeal tuberculosis, while relatively well recognized in the adult population, is a rare disease in chidren and adolescents. There are few reports of intestinal tuberculosis combined with endobronchial and laryngeal tuberculosis in children. We have experienced a case of intestinal tuberculosis which concurred with endobronchial and laryngeal tuberculosis in an 18-year-old girl who presented with abdominal pain, diarrhea, weight loss, a brassy cough, and anemia, which was diagnosed by a colonoscopy and bronchoscopy with biopsy.

Saururus chinensis (SC) belongs to the dicotyledonous plants, and its roots, leaves and flowers are white, so it is named three hundred and seconds. It is mainly distributed in Korea, China and Japan. In Korea, it is a native plant distributed in Jejudo and Jirisan areas. It has been known to improve blood circulation, anticarcinogenic effects and purge. However, studies of the efficacy on digestive system is few. This study was conducted to evaluate the effects of oral administered-SC extract in loperimide-induced constipation rats. The amount, weight and water content of the stools were measured. The number and type of stools in the large intestines were measured, and the amount of intestinal mucus was analyzed by serological analysis and histologic special staining. The severity of constipation in SC groups was significantly less than that in control group (non-SC rats). Digital Image processing also showed weaker inflammation on the large intestines of SC groups than that of control group (non-SC group). Especially, with increased dose dependent manner of SC extract, the amount and integrity of intestinal mucus increased. These results suggest that SC extract may prevent the symptoms of constipation.

Ekong-san(EKS) was expected to have inhibitory effects on angiogenesis, considering the fact that its constituents such as Ginseng Radix, Glycyrrhizae Radix and Citri Pericarpium were reported to inhibit angiogenesis. Moreover, recently several metabolites transformed by the human intestinal microflora were reported to enhance effectiveness compared to their crude drugs. Based on these data, this study was designed to confirm whether the EKS metabolites (EKS-M) can significantly exert the anti-angiogenic and anti-metastatic activites. Hence, with EKS and EKS-M, viability assay, proliferation assay, in vitro tube formation assay, gelatin zymogram assay, in vitro invasion assay were carried out. EKS showed less toxicity in ECV304 and HT1080 cells than EKS-M. EKS-M inhibited the proliferation of HT1080 cells by 30% at 200㎍/㎖ and 42% at 400 ㎍/㎖ respectively. Also, EKS-M degraded the tube network at 200㎍/㎖. EKS and EKS-M inhibited the expression of MMP-9 at 200 and 400㎍/㎖ in HT1080 cells. EKS reduced the invasive activity of HT1080 cells through matrigel coated transfilter atthe concentration of 200㎍/㎖ more effectively than EKS-M. These data suggest that EKS and EKS-M has anti-angiogenic and anti-metastatic activities.

Background: Gastric cancer is the second most common gastrointestinal cancer and is largely attributed to Helicobacter pylori (H. pylori) infection. In addition, studies have also shown association with Epstein-Barr virus (EBV) in 10% of gastric cancers. This study assessed the characteristics of EBV associated gastric cancers (EBVaGC) in Brunei Darussalam. Materials and Methods: This study included gastric cancers diagnosed between 2008 and 2012, registered with the Department of Pathology RIPAS Hospital, Brunei Darussalam. Clinical case notes were systematically reviewed. Histology specimens were all stained for EBV and also assessed for intestinal metaplasia and H. pylori. Results: There were a total of 81 patients (54 male and 27 females) with a mean age of $65.8{\pm}14.8years$ included in the study. Intestinal metaplasia and active H. pylori infection were detected in 40.7% and 30.9% respectively. A majority of the tumors were proximally located (55.6%), most poorly differentiated (well differentiated 16%, moderately differentiated 30.9% and poorly differentiated 53.1%) and the stages at diagnosis were; stage I (44.4%), stage II (23.5%), stage III (8.6%) and stage IV (23.5%). EBV positivity (EBVaGC) was seen in 30.9%. Between EBVaGC and EBV negative gastric cancers, there were no significant differences (age, gender, ethnic group, presence of Intestinal metaplasia, tumor locations, stages of disease and degree of tumor differentiation). Conclusions: This study showed that a third of gastric cancers in Brunei Darussalam were positive for EBV, higher than what have been reported in the literature. However, there were no significant differences between EBVaGC and EBV negative gastric cancers. This suggests that the role of EBV in gastric cancer may be mostly incidental rather than any causal relation. However, further studies are required.

Background: Modified toluidine blue staining (MTBs) is a simple, inexpensive and time saving method to detect H. pylori in gastric biopsy specimens. As a metachromatic stain, it simultaneously highlights intestinal metaplasia, a gastric cancer precancerous lesion. The aim of this study was to assess the reliability of MTBs compared with hematoxylin-eosin (H&E) for H. pylori detection using immunoperoxidase staining as the gold standard. This technique would be beneficial for a routine diagnosis and confirmation of H. pylori eradication in developing countries where endoscopic-based approaches are dominant. Materials and Methods: Esophagogastroduodenoscopy with triple site gastric biopsies was undertaken in 207 dyspeptic patients at Thammasat University Hospital, Thailand between 1997 and 1999. H&E, MTBs and immunoperoxidase staining were applied to each specimen. The presence or absence of H. pylori with each stain was interpreted separately and the sensitivity, specificity, positive and negative predictive values of H&E and MTBs were calculated. Results: A total of 282 specimens from 207 patients were evaluated. Using immunoperoxidase staining, organisms were positive in 117 specimens (41%). MTBs proved almost equally sensitive as immunoperoxidase (99%) and significantly more sensitive than H&E (85%). It has comparable specificity (96% vs 96%), PPV (95% vs 94%), and NPV (99% vs 90%) to H&E, using immunoperoxidase staining as gold standard. MTBs compared with immunoperoxidase staining, is cheaper (2 USD vs 12 USD) and faster (20 min vs 16 hrs) compared to immunoperoxidase staining. Conclusions: MTBs is effective, economical and easy to use in daily practice for the detection of H. pylori in gastric biopsy specimens. In addition to saving time in evaluating H. pylori associated gastritis, with a high sensitivity and ability to demonstrate intestinal metaplasia, the technique may have a role in confirmation of H. pylori eradication for gastric cancer prevention in a developing country setting.

The purpose of this study was to examine the effects of Angelica gigas Nakai on ulcerative colitis. Mice were divided into 5 groups: Control group, DSS group, 5-ASA group, 50mg/kg Angelica gigas Nakai group, 100mg/kg Angelica gigas Nakai group. Four groups, excluding the control group, were fed a 5% solution of dextran sulfate sodium(DSS) in water for 7days to induce ulcerative colitis. Each water extract was administrated orally for 7 days in 5-ASA group, 50mg/kg Angelica gigas Nakai group and 100mg/kg Angelica gigas Nakai group. 5 groups were evaluated by weight, length of intestine, weight of spleen, disease activity index(DAI), amount of cytokine IL-6 production, thickness of bowel wall and degree of inflammatory cell infiltration and intestinal tissue damage. Comparing to DSS group, 100 mg/kg Angelica gigas Nakai group showed significant suppressive effect of weight loss until 4th day of experiment while 50 mg/kg Angelica gigas Nakai group showed no significant effect of suppression. Decrease of intestinal length, enlargement of spleen, intestinal tissue damage and thickening of bowel wall were significantly suppressed in both 50 mg/kg and 100mg/kg Angelica gigas Nakai group. Also disease activity and cytokine IL-6 production were inhibited significantly. Based on this result, Angelica gigas Nakai seemed to have anti-inflammatory effect and also seemed to suppress histological changes and aggravation of ulcerative colitis.
