Solitary rectal ulcer syndrome (SRUS) is a rare disorder in children. There are few investigations about the exact incidence and effective treatment of SRUS in children. We describe a 12-year-old male patient who had rectal prolapse for 9 years, hematochezia for 7 months, and was diagnosed with polypoid solitary rectal ulcer syndrome with rectal prolapse by colonoscopy. Anorectal manometry was also performed to evaluate the cause of frequent relapses.

Four dogs were brought to the Veterinary Medicine Teaching Hospital of Seoul National University (VMTH SNU) with a history of hind limb ataxia, three with pain, one without pain. Three of the four showed weak to absent femoral pulses and cold extremities. Thromboembolism was identified by ultrasonography in the external and/or internal iliac arteries. A thrombolytic agent, recombinant tissue plasminogen activator (rt-PA), was administered (0.5-1 mg/kg, every 60-120 min, 3-5 doses). Two dogs (Cases 2 and 3), which were instantly provided rt-PA treatment, survived 6 and 17 months, respectively, although hematemesis and hematochezia were observed during treatment. In the other two dogs (Cases 1 and 4), rt-PA was administered 4 and 28 days after the appearance of pelvic limb symptoms, which may have limited the benefits of the treatment. When rt-PA treatment is instituted instantly and the side effects are monitored thoroughly during treatment, a good prognosis might be expected in canine aortic thromboembolism. For this reason, we suggest that rt-PA treatment should be initiated immediately if thromboembolism is identified.

Our records include two cases of DIC in snakebite patients. One patient, who was 48-years old, was bitten in his left ankle 3 days before admission to our hospital. Initial symptoms were painful swelling, extensive ecchymosis, and persistent bleeding at the bite site. He visited and was admitted to a local hospital, but his condition did not improve with supportive care that included a single dose of antivenin. He was transferred to our hospital. His condition was compatible with DIC. We tried multi-dose antivenin therapy and blood product transfusion. At the seventh hospital day, the patient's symptoms were completely resolved. The other patient, who was 75 years old, was bitten in his right thumb. Initial symptoms were painful swelling of the right arm and persistent bleeding at the bite site, and within minutes of hospital admission, the patient experienced massive hematochezia. We peformed laboratory tests, the results of which were compatible with DIC, and the next day a sigmoidscopic examination showed ischemic colitis. We administered multi-dose antivenin therapy and blood product tranfusion. At the third hospital day mild anemia still existed, but the patient's clinical condition was improved. No signs or symptoms of gastrointestinal bleeding were observed. In these two cases, multi-dose antivenin therapy and transfusion effectively resolved symptoms of DIC. Platelet concentrate transfusion was required only for acute thrombocytopenia. After resolution of DIC, platelet counts were returned to normal ranges within a few days. The authors propose that multidose antivenin therapy and coagulation factor transfusion might be useful for improving coagulopathy in snakebite patients.

Turcot syndrome is characterized by the concurrence of a primary neuroepithelial brain tumor and multiple colorectal polyposis. We report a case of a 24-year-old woman diagnosed with Turcot syndrome. At first, the patient was diagnosed as having a medulloblastoma after a tumorectomy of the 4th ventricle mass. The patient underwent radiotherapy and chemotherapy. After high-dose chemotherapy, neutropenic fever and severe mucositis developed. For an evaluation of the persistent hematochezia and diarrhea, a colonoscopy was performed. It revealed pseudomembranous colitis and multiple polyps in the entire colon. According to the family history, her father had undergone a total colectomy due to colon cancer and polyposis of the entire colon. Her brother also was found to have multiple polyps in the colon by a colonoscopy. The patient was diagnosed with Turcot syndrome.

Dysfunction of gut immune regulation is involved in mucosal damage in inflammatory bowel disease (IBD). However, there is still no efficacious immune-regulator for the treatment of IBD. Alloferon is a novel immune-modulatory peptide that was originally isolated from infected insects. It shows anti-inflammatory effects by the regulation of cytokine production by immune cells and their activities. Therefore, we investigated the effect of alloferon in a mouse model of colitis using dextran sulfate sodium (DSS). Colitis was induced by administration of DSS in drinking water for 7 consecutive days. It was confirmed by the presence of weight loss, diarrhea, hematochezia, and colon contraction. Alloferon was injected 4 days after DSS administration. We found that alloferon improved the pathogenesis of IBD based on the reduced disease activity index (DAI) and colon contraction. Edema, epithelial erosion, and immune cell infiltration were found in mice administered DSS, but the phenomena were reduced following alloferon treatment. The plasma level of IL-6, a classical pro-inflammatory cytokine in colitis, was also decreased by alloferon. Moreover, alloferon inhibited the TNF-${\alpha}$-induced degradation and phosphorylation of $I{\kappa}B$ in Colo205 colon cancer cells. Taken together, these results show that alloferon has anti-inflammatory effects and attenuates DSS-induced colitis.

Henoch-Sch$\ddot{o}$nlein purpura (HSP) is a leukocytoclastic vasculitis of small vessels with deposition of IgA, commonly resulting in skin, joint, gastrointestinal, and kidney involvement. HSP is an uncommon disorder in adults and accounts for 0.6% to 2% of adult nephropathy. We report a case of HSP with acute renal failure successfully treated with corticosteroid. In this case, the patient presented with vasculitic purpuric rash on lower extremity, arthralgia in the wrist, abdominal pain, hematochezia, oliguria and azotemia. Abdominal CT showed wall thickening of the small and large bowels. Skin biopsy revealed leukocytoclastic vasculitis. Percutaneous renal biopsy showed no crescent formation, but mesangial IgA and $C_3$ deposits were observed by immunofluorescence. The patient was treated with corticosteroid (1mg/kg per day) and hemodialysis. After treatment, renal function improved and purpuric lesion, arthralgia and abdominal pain disappeared. Thus, when adults present with purpuric rash and rapidly progressive glomerulonephritis (RPGN), HSP should be a diagnostic consideration.

Gastrointestinal involvement in Henoch-Sch$\"{o}$nlein purpura (HSP) is common. However, both acute pancreatitis and acute renal failure appear to be very rare complications of HSP. We describe a case of HSP with acute pancreatitis and hypovolemic acute renal failure in a 7-year-old girl who presented with a vasculitic purpuric rash involving the lower extremities, abdominal pain, hematochezia, vomiting, and oliguria. Laboratory findings showed increased serum levels of amylase, lipase, and creatinine. An abdominal CT scan revealed diffuse enlargement of the head and body of the pancreas. The patient was successfully managed with conservative treatment, including corticosteroids, and then her pancreatic enzymes and renal function returned to normal. Acute pancreatitis should be differentiated from other causes of acute abdomen in HSP to avoid unnecessary surgery.

An indirect immunofluorescent antibody test was applied to survey the antibody prevalence on five canine viruses including canine distempervirus(CDV), canine parvovirus(CPV), canine coronavirus(CCV), canine adenovirus type-2(CAV-2), canine parainfluenzavirus(CPIV) in dogs. The period studied was from October 1992 to June 1993. A total of 80 dog sera was collected from veterinary clinics in Kwangju and Seoul, and examined for the presence of virus antibodies. Immunofluorescent antibodies(IFA) to all viruses were present in a high percentage of 80 sera tested. Seventyfive(93.8%) showed detectable IFA against CPV, 67(83.8%) against CDV, 51(63.8%) against CCV, 42(52.5%) against CPIV and 34(42.5%) against CAV-2. These suggested that all viruses were endemic in the communities. IFA levels against each virus were also distributed fairly irregularly. IFAs for CDV and CPV were detected more frequently with a relatively high incidence in vaccinated group less than 1 years of age. IFAs for CAV-2 were detected more frequently with growing age. In the correlation of clinical signs and antibody prevalence, dogs that showed hematochezia and vomiting had high titers in the positive sera is noteworthy, particularly for CDV and CPV. The significance between dogs those who had diarrhea, dyspnea and salivation and those viruses were obscure.

Ulcerative colitis, an inflammatory bowel disease, is primarily managed medically with a combination of 5-ASA and steroids. However, this chronic disease requires surgical management if symptoms persist or complications develop despite medical management. The clinical course, indications and outcome of surgical management of 21 patients under the age of 15 who were endoscopically diagnosed with ulcerative colitis at the Seoul National University Children's Hospital between January, 1988 and January, 2003 were reviewed. Mean follow up period was 3 years and 10 months. The mean age was 10.3 years old. All patients received medical management after diagnosis and 8 patients (38 %) eventually required surgical management. Of 13 patients who received medical management only, 7 patients (53 %) showed remission, 4 patients are still on medical management, and 2 patients expired due to congenital immune deficiency and hepatic failure as a result of sclerosing cholangitis. In 8 patients who received surgical management, the indications for operation were, 1 patient sigmoid colon perforation and 7 patients intractability despite medical management. The perforated case had a segmental colon resection and the other 7 patients underwent total colectomy with ileal pouch-anal anastomosis. One patient expired postoperatively due to pneumonia and sepsis. and 1 is still on medical management because of mild persistent hematochezia after surgery. Six other operated patients are doing well without medical therapy. Pediatric ulcerative colitis patients can be surgically managed if the patient is intractable to medical management or if complications such as perforation are present. Total colectomy & ileal pouch-anal anastomosis is thought to be the adequate surgical method.

The flower buds of Sophora japonica L (SF), as a well-known traditional Chinese medicinal herb, have been used to treat bleeding-related disorders such as hematochezia, hemorrhoidal bleeding, dysfunctional uterine bleeding, and diarrhea. However, no specific anti-cancer effect and its molecular mechanism of SF have been described. Thus, we performed in vitro study to investigate if treatment of SF affects activating transcription factor 3 (ATF3) expression and ATF3-mediated apoptosis in human colorectal cancer cells. The effects of SF on cell viability and apoptosis were measured by MTT assay and Western blot analysis against cleaved poly (ADP-ribose) polymerase (PARP). ATF3 activation induced by SF was evaluated using Western blot analysis, RT-PCR and ATF3 promoter assay. SF treatment caused decrease of cell viability and increase of apoptosis in a dose-dependent manner in HCT116 and SW480 cells. Exposure of SF activated the levels of ATF3 protein and mRNA via transcriptional regulation in HCT116 and SW480 cells. Inhibition of extracellular signal-regulated kinases (ERK) 1/2 by PD98059 and p38 by SB203580 attenuated SF-induced ATF3 expression and transcriptional activation. Ectopic ATF3 overexpression accelerated SF-induced cleavage of PARP. These findings suggest that SF-mediated apoptosis may be the result of ATF3 expression through ERK1/2 and p38-mediated transcriptional activation.
