A 16-year-old, spayed female, Maltese dog weighing 4.3 kg was presented with a 2-week history of yellowish nose-and oral-discharge, anorexia and lethargy. In physical examination, indefinite ulcerative mass about $3{\times}3$ cm in size in the left sublingual region, severe gingivoperiodontitis, halitosis, moderate dental calculus, fever and swelling of mandible soft tissue were noted. In radiographic view, periodontitis and bone lysis findings on the left rostral part of maxilla and mandible were observed. In complete blood count and blood chemistry test, thrombocytosis, increased levels of serum $NH_3$, AST and ALP were obtained. Urinalysis revealed hematuria and proteinuria. In histological examination, squamous cell carcinoma was diagnosed. No surgery was performed, but combined treatment with carboplatin and piroxicam was initiated. Five days after initiation of medication, because of insistent vomiting, piroxicam was substituted to meloxicam. Although the therapeutic efficacy of meloxicam could not be known; administration of meloxicam might be less potential to gastrointestinal side-effects than piroxicam. The dog totally received 3 times of carboplatin infusion. Five days after third infusion of carboplatin, the dog was hospitalized with severe lethargy, vomiting and bloody diarrhea. In examination, severe renal failure signs were noted, and the dog was euthanized.

A seven-year-old, castrated male Basset hound weighing 21.1 kg was presented for investigation of anorexia, lethargy, weight loss, melena and vomiting for 4 months. In laboratory findings, microcytic hypochromic anemia was identified, and other results were within a normal reference range. On the plain radiographs, soft tissue opacity was increased in the descending duodenal region; and on the contrast radiographs, ulcerative changes were identified in the entire segment of descending duodenum. Ultrasonographic findings included increased duodenal wall thickness and duodenal wall layering was lost. Endoscopy revealed irregular mucosal surface and luminal narrowing of the descending duodenum. There was concentrically thickened descending duodenum on the computed tomography. And the wall of the descending duodenum showed heterogenous enhancement after contrast agent injection. On histopathological findings, both chronic inflammation with mucosal proliferation and neoplastic changes with multiple small glandslike structures invading into the submucosa were identified. Based on these findings, presented case was diagnosed as an annular form duodenal adenocarcinoma. After 13 months of supportive medical treatment, the patient was expired. The purpose of this case report was to describe the duodenal adenocarcinoma in a dog.

Motherwort (Leonurus sibiricus L), a hemp nettle (Labiatae) plant, grows about 1.5${\~}$2 m high spontaneously to wildness in Korea, China, Japan, and other Asian place. Its medical applications includes women's uterine disease, urination, bloody stool, bloody urine, and hemorrhoids. It's also effective for high blood pressure, heart stimulation, and anti-cancer activity. We first prepared chlroform and methanol extracts of motherwort and then they were fractionated using water, $30\%$ methanol, $60\%$ methanol, and $100\%$ methanol, respectively. Each fractionates is assayed for free radical scavenging activities against DPPH and anti-oxidant activity by TBARS assay measuring lipid peroxidation using LDL. The $30\%$ and $60\%$ methanol fractionates of methanol extracts showed strong anti-oxidant activity compared to vitamin C. They also had more Potent SOD activity using pyrogallol at 250 ppm than that of vitamin C. These results suggest that anti-oxidant activities of motherwort may be applicable to development of natural anti-oxidant cosmetics. Possibility of nature anti-oxidation ability cosmetics is seen possibility low official.

Toxic megacolon is a fatal complication of inflammatory or infectious bowel disease. Prognosis depends on the severity of the disease. In cases of poor prognosis, clinical outcomes range from intestinal resection to death, so early diagnosis and appropriate treatment are very important. However, the prevalence of toxic megacolon in children is very low, and in those without underlying diseases such as inflammatory bowel disease, early diagnosis may be delayed. A previously healthy 12-year-old boy presented to our hospital with lower abdomen pain, fever, and hematochezia. Despite antibiotic therapy, the symptoms worsened. On the third day, abdominal computed tomography revealed severe dilatation of the transverse colon, which indicated toxic megacolon. Stool culture was positive for Salmonella enteritidis group D, and rectal endoscopy showed no signs of inflammatory bowel disease. Ceftriaxone and intravenous methylprednisolone were administered, and the patient's condition improved without any complications. We report a case of toxic megacolon as a complication of infectious colitis caused by S. enteritidis group D, which was diagnosed using early imaging and successfully treated without surgical intervention.

This is a rare case of a 73-year-old male patient who presented with hematochezia and was treated using transcatheter arterial embolization following upper gastrointestinal bleeding in the third portion of the duodenum. The cause of the bleeding was not found on gastrointestinal endoscopy and CT. On the third day of hospitalization, the hemoglobin level continued to decrease. A technetium-99m-labeled red blood cell scan revealed suspicious bleeding in the diverticulum of the third portion of the duodenum. Superior mesenteric artery angiography showed active bleeding from the posteroinferior pancreaticoduodenal artery, which was embolized with N-butyl cyanoacrylate. The patient was discharged on the seventh day after embolization without re-bleeding or complication. We report a rare case of a patient with active bleeding from a duodenal diverticulum that was difficult to diagnose using routine modalities. Herein, we report a rare case of a patient with active bleeding from a duodenal diverticulum that was difficult to diagnose using routine modalities. We also conducted a relavant literature review.

Purpose This study aimed to evaluate the efficacy and safety of transcatheter arterial embolization (TAE) for bleeding due to uterine body cancer. Materials and Methods In this retrospective study, six patients with varying types of uterine body cancer who underwent TAE for bleeding control were investigated. Angiographic findings, cross-sectional images, TAE details, and clinical outcomes were studied. Technical and clinical success rates were calculated. Results The identified patients had endometrioid adenocarcinoma, sarcoma, and gestational trophoblastic neoplasia, and most were patients with advanced-stage cancer. In four patients, tumor bleeding presented as vaginal bleeding. Technical success was achieved in all seven TAE procedures in six patients. Two patients with recurrent masses who had undergone hysterectomy presented with hematochezia, and TAE was able to provide technical success in these patients as well. The clinical success rate was 50%, indicating bleeding control for > 1 week. Rebleeding was directly associated with death in one patient. On the following day, mild fever was observed in one patient. Conclusion TAE can be considered an effective and safe method of bleeding control for uterine body cancer, especially during critical periods throughout the disease course of patients with inoperable, advanced-stage cancer.

Purpose: The aim of this study is to investigate the usefulness of intestinal ultrasonography (US) and upper gastrointestinal endoscopy in the early diagnosis of Henoch-Sch$\"{o}$nlein purpura (HSP) with the gastrointestinal (GI) symptoms preceding the emergence of the skin lesion. Methods: The clinical, intestinal US and upper gastrointestinal endoscopic records of 85 patients (88 cases) with GI symptoms relating to HSP presenting between January 1999 and April 2001 were reviewed. Results: 1) GI symptoms were observed in 52 cases (59%) and skin, joint, renal and scrotal manifestations were observed in 88 (100%), 64 (73%), 15 (17%), 3 cases (3%) respectively. 2) Out of 52 cases with GI symptoms, abdominal pain was observed in all cases (100%). Positive stool occult blood, nausea and vomiting, abdominal tenderness, melena or tarry stool, diarrhea, hematemesis, rebound tenderness and rigidity were observed in 28 (50%), 17 (33%), 17 (33%), 12 (23%), 6 (12%), 4 (8%), 1 (2%) and 1 case (2%) respectively in order of frequency. 3) Intestinal US examination was performed in 27 cases with HSP and GI symptoms (52 cases). Out of 27 sonographic examinations 22 showed abnormal findings. Thickening of the duodeno-jejunal wall was observed in 16 cases (73%). Free peritoneal fluid, enlarged mesenteric lymph node, ileus and abnormal gall bladder were seen in 8 (36%), 8 (36%), 4 (18%) and 1 case (5%) respectively. In three cases of HSP without GI symptoms, those changes were absent. 4) In all of five cases with HSP and GI symptoms, endoscopic study showed mucosal edema and multiple hemorrhagic erosions especially at the second portion of the duodenum. Biopsy specimens from the duodenum of 2 cases out of 5 endoscopic examinations showed acute inflammatory infiltrates in the mucosa with hemorrhage. 5) Both intestinal US and endoscopic studies were performed in 4 cases with HSP and GI symptoms simultaneously. Out of 4 those cases, 3 cases showed the thickened duodeno-jejunal wall on the intestinal US, which suggested erosive hemorrhagic duodenitis by endoscopic findings. Conclusion: The typical but nonpathognomonic intestinal US findings including the thickening of the duodeno-jejunal wall and upper gastrointestinal endoscopic findings including hemorrhagicerosive duodenitis, in children with GI symptoms, should be considered a manifestation of HSP, even in the absence of skin lesion.

Purpose: Lymphonodular hyperplasia of the colon (LNHC) is a rare finding in children and its significance as a pathologic finding is unclear. The aim of this study was to investigate the clinical significance of LNHC by analyzing clinical and histopathologic findings in children with LNHC. Methods: We analyzed data from 38 patients who were confirmed to have LNHC by colonoscopy. We checked age, birth history, past history, family history, and clinical symptoms. A hematologic exam, stool exam, and image studies were performed and biopsy specimens were examined by a pathologist. All patients were asked to have short- and long-term follow-up. Results: The mean age of the patients was 12.5${\pm}$14.4 months. All patients presented with complaints of bloody stool. They appeared healthy and the hematologic findings were within a normal range, with the exception of one case. There was no other identified source of bleeding. On histologic exam, 36 patients (94.7%) had lymphoid follicles and 34 patients (84.5%) fulfilled the criteria of allergic colitis. Regardless of diet modification and presence of residual symptom, there was no recurrence of bloody stool through long-term follow-up in all patients. Conclusion: LNHC is more common in infants who are affected by allergic colitis, but it can appear even after infancy. LNHC should be regarded as the etiology when there are any other causes of rectal bleeding, especially in healthy children. We suggest that LNHC has a benign course regardless of diet modification and it might not require excessive concerns.

Purpose : Henoch-$Sch{\ddot{o}}nlein$ purpura(HSP) is a systemic vasculitis, characterized by cutaneous palpable purpura, gastrointestinal(GI) symptoms, arthritis and renal involvement. In general, the prognosis is determined by GI complication as well as the severity of nephritis. In this study, we analyzed the statistical relationship between the GI symptom and other clinical findings for assessing the prognosis, and evaluated abdominal ultrasonographic findings for early diagnosis of this disease with atypical clinical presentation and early detection of serious GI complications. Methods : One hundred seventy seven patients with HSP in the Department of Pediatrics, Wonkwang University Hospital from January 1994 to June 2004, were enrolled. We retrospectively analyzed charts about clinical and abdominal ultrasonographic findings, and classified our patients into two groups(GI-Sx(-), GI-Sx(+)) for statistical analysis. Results : The ratio of female to male is 1.5 : 1. The peak age incidence was five to eight years in 95 cases(53%). The GI symptoms appeared in 117 cases(66%), which include abdominal pain 115 (98 %), tenderness 45(38%), nausea and vomiting 35(30%), bloody stool 10(8.5%), diarrhea four(3.4%), rebound tenderness four(3.4%), and also intussusception and appendicitis were complicated in five and two cases respectively. GI-Sx(+) group had an increased risk of renal involvement and relapse than the GI-Sx(-) group. But there were no relationships about sex and age incidence, or other clinical and laboratory findings between two groups. Ultrasonographic findings in 98 patients with GI symptoms included small bowel thickening in 70 cases(71%) in which duodenum, jejunum and ileum were involved in 71%, 45.7%, 40% respectively, small bowel dilatation in 41 cases(42%), lymph node swelling in 46 cases(47%), and ascites in 25 cases(25.5%). Conclusion : GI symptoms in patients with HSP suggested increased risk of renal involvement and relapse. Abdominal ultrasonography could be helpful in the early diagnosis on atypical clinical presentation and early detection of serious GI complication in these patients.

Purpose : Idiopathic thrombocytopenic purpura (ITP) is a relatively common hematological disease in children. It generally occurs after exposure to a common viral infection episode; however, it may occasionally follow immunization with measles, measles-mumps-rubella (MMR), hepatitis B (HBV), influenza, diphtheria-tetanus-pertussis (DTP), or chickenpox vaccines. In this study, the incidence, clinical characteristics, and treatment outcome of vaccination-associated ITP were investigated and compared with non-vaccination-associated ITP. Methods : The admission records of 105 pediatric ITP patients between 0-14 years of age admitted to Department of Pediatrics, Wonkwang University Hospital from January 1994 to July 2007 were retrospecitively reviewed. Patients were grouped into a vaccination-associated group and a non-vaccination-associated group according to vaccination history within the previous 1 month, and various clinical features between the two groups were statistically analyzed. Results : Thirteen patients (12%) had a preceding vaccination. Eight had received DTP vaccination, 2 had received hepatitis B, and 1 each had received influenza, MMR, and Japanese B encephalitis vaccination. However, none of the patients had a recurrent thrombocytopenia after subsequent vaccinations. In the vaccination-associated group, the age was significantly lower, anemia was more common, and the risk period with blood platelet count $<20{\times}10^9/L$ was significantly shorter than for the in non-vaccination-associated group. Also, wet purpura was less prominent and the remission within 1month was more frequently achieved in the vaccination-associated ITP group. Conclusion : Vaccination-associated ITP patients showed mild symptoms with a more benign and shorter lasting course than non-vaccination-associated ITP patients. Moreover, platelet count assessment at the time of the next immunization may not be necessary.
