OBJECTIVETo study the clinical effect of Tongxie Yaofang (TXYF) Granule in treating diarrhea-predominate irritable bowel syndrome (D-IBS) and its possible mechanism.

METHODSA total of 120 patients were assigned to two groups using stratified block randomization, 80 in the intervention group and 40 in the control group. To the intervention group the TXYF granule was given at one package each time, twice a day; the control group was treated with Miyarisan three times a day, two tablets each time. The course of treatment was 4 weeks for both groups. The total efficacy in them was compared, and data of scoring on stool (Bristol method), abdominal pain, abdominal distension, and mental condition were collected before treatment and 2 and 4 weeks after treatment. The activation of mast cells (MCs) of six patients chosen from each group was detected as well before and after treatment.

RESULTSNo significant difference between the two groups in terms of the total efficacy or the scores of symptoms before and after treatment was found (P>0.05). The number of activated MCs was decreased in the intervention group after treatment, showing significant difference as compared with that before treatment as well as with that in the control group after treatment (P<0.01).

CONCLUSIONSTXYF is an effective preparation for the treatment of D-IBS. It can quickly lessen abdominal pain and distention, improve the property of stool, and improve mental tension and depression in patients. Its mechanism of action might be through the adjustment of MCs activation to decrease visceral hypersensitivity.

Anisakidae larvae can cause anisakiasis when ingested by humans. Although several groups have reported a gastrointestinal Anisakis allergy among people in Spain and Japan, our report is the first to summarize the clinical features of 10 Anisakis allergy cases in Korea. We enrolled 10 Korean patients (6 men and 4 women) who complained of aggravated allergic symptoms after ingesting raw fish or seafood. Sensitization to Anisakis was confirmed by detecting serum specific IgE to Anisakis simplex. The most common manifestation of anisakiasis was urticaria (100%), followed by abdominal pain (30%) and anaphylaxis (30%). All patients presenting with these symptoms also exhibited high serum specific IgE (0.45 to 100 kU/L) to A. simplex. Nine patients (90%) exhibited atopy and increased total serum IgE levels. The fish species suspected of carrying the Anisakis parasite were flatfish (40%), congers (40%), squid (30%), whelk (10%), and tuna (10%). Anisakis simplex should be considered as a possible causative food allergen in adult patients presenting with urticaria, angioedema, and anaphylaxis following the consumption of raw fish or seafood.

Mast cells, which are major effector cells in allergic reactions, are found in the perivascular spaces of most tissues and contain pro-inflammatory and vasoactive mediators. These mediators are released after IgE receptor cross-linking induced by allergens or other stimuli, including anaphylatoxins (C3a and C5a), aggregated IgG, certain drugs, venoms, and physical stimuli (pressure and temperature changes), as well as cytokines and neuropeptides. The excess release of these mediators can cause variable allergic symptoms and signs, such as bronchospasm, itching, flushing, nausea, vomiting, diarrhea, abdominal pain, vascular instability, and anaphylaxis. Furthermore, mast cell disorders may involve either excessive proliferation of mast cells or abnormal mast cell reactivity. Mast cell disorders can be broadly divided into 3 types: primary, secondary, and idiopathic. All of these disorders present with signs and symptoms of mast cell activation and differ in severity and involvement of various organ systems. The best characterized primary disorder is mastocytosis. Systemic and cutaneous forms of the disease are well described. Secondary disorders include typical allergic diseases and some types of urticarial diseases. In this article, the biochemical characteristics of mast cells and the role of mast cells in allergic inflammation, as well as the classification, diagnosis, and management of mast cell-related disorders, will be reviewed.

A 25-year-old Uzbek male presented with right upper abdominal pain for 20 days. On radiologic studies, a huge cystic mass was noticed in the right liver which was suspected as parasitic. The patient received right hepatic segmentectomy (segment 7), and the surgically resected mass was confirmed as cystic echinococcosis (CE), measuring 10.5 cm in its diameter. The inner surface of the cyst was bile-stained. The patient was discharged on the 8th hospital day, and was rechecked 6 months after the surgical intervention without any evidence of recurrence. The present report describes findings of an imported case of CE which represented ultrasound images of the 'ball of wool'.

BACKGROUND/AIMS: Clinical manifestations of intestinal yersiniosis include enterocolitis, mesenteric adenitis, and terminal ileitis presenting with fever, right lower quadrant pain, and leukocytosis. According to a previous Korean study in 1997, Yersinia was revealed in two among 15 adult patients with mesenteric adenitis (13%). However, recent reports on the prevalence of Yersinia infection in adult patients are few. The aim of this study was to investigate the prevalence of Yersinia infection in adult patients with acute right lower quadrant pain. METHODS: Adult patients (>18 years) who visited Eulji medical center, due to acute right lower quadrant pain were enrolled prospectively from December 2007 to July 2009. Abdominal CT, stool culture, serologic test for Yersinia, and Widal test were performed. RESULTS: Among 115 patients, 5 patients were excluded due to positive Widal test or salmonella culture. In 110 patients, abdominal CT showed right colitis in 20 (18.2%), terminal ileitis in 16 (14.5%), mesenteric adenitis in 13 (11.8%), acute appendicitis in 10 (9.1%), acute diverticulitis in 7 (6.4%), non specific mucosal edema in 36 (32.7%) and no specific lesion in 8 (7.3%). Two (1.8%) of the 110 patients had antibodies to Yersinia. One patient showed acute enteritis and the other patient was diagnosed with acute appendicitis and underwent appendectomy. No Yersinia species were grown on stool or tissue culture. CONCLUSIONS: Nowadays, among adult Korean patients presenting with acute right lower quadrant pain, there have been few incidences of Yersinia infection.
