Antral web is a very rare cause of vomiting in child, known to be a congenital disorder caused by incomplete recanalization of embryonic foregut, and in almost cases treated surgically. Author experienced a case of antral web in a 4-year-old boy who had suffered from severe abdominal pain for 2 months, in whom erosive duodenitis was noted on endoscopic examination. The patient became symptomfree after 1 week of conservative treatment for duodenitis. No specific therapy was not required for the antral web. Author concluded that surgical treatment is indicated for the clinically severe cases.

After the percutaneous transarterial technique was introduced by Seldinger in 1953, the percutaneous transcatheter embolization technique was developed. Autologous clot, first used by Doppman in 1968 to occlude a spinal arteriovenous malformation, was quickly adopted for management of gastrointestinal hemorrhage, genitourinary hemorrhage, traumatic hemorrhage, and hemoptysis. The notable improvement of the angiographic techniques rendered the interventional treatment the mainstay in the management of bleeding. Interventional treatment can be a life-saving procedure for massive bleeding or an important adjunct in reducing blood loss during operation and occasionally radical treatment of bleeding diseases. The goal of embolotherapy is to reduce the pulse pressure in the bleeding artery while maintaining an enough collateral flow to preserve the tissue viability. A variety of embolic materials have been proved safe and effective. Gelfoam pledget, polyvinyl alcohol, and coil are most commonly used. Gelfoam powder, extremely small polyvinyl alcohol, and absolute alcohol should be used carefully because of the risk of mucosal ischemia and necrosis.

Six cases of right external iliac and common femoral arterial thrombotic occlusions following transfemoral cardiac catheterization were found among the 117 infants and children with congenital heart disease. Physical findings of arterial thrombosis were lower extremity coldness and absence of femoral pulse, which appeared just after cardiac catheterization. Transcatheter local intrathrombotic infusion of Urokinase were done with 50000 IU bolus doses and 40000-50000 IU/h running doses. All 6 cases showed complete thrombolysis and re-establishment of femoral circulation. Three cases developed bleeding from arterial puncture sites, and were subsequently controlled properly by compression. No other complication was found. Our results suggest that local thrombolytic therapy with Urokinase is effective treatment method without significant complication for the infants and children with fresh thrombotic occlusions following cardiac catheterization and angiography.

In order to study the histogenesis of gastric carcinoma, and to find the correlationship between the gastric carcinoma and endocrine tumor of digestive tract, we performed immunoperoxidase staining for serotonin, somatostatin and gastrin respectively in the 34 cases of surgically resected gastric carcinoma. The results were as follows; 1) Endocrine cells were found in 26.5% (9/34) of the gastric adenocarcinoma, but in 58.6% (17/29) in the normal gastric mucosa near the cancer area. The occurrence of endocrine cells was less frequent in cancer than in the normal gastric mucosa. 2) Among the 15 cases of intestinal type adenocarcinoma, serotonin-positive cells were found in 2 cases, somatostatin-positive cells in 1 case and gastrin-positive cells in 1 case. Among 16 cases of diffuse type adenocarcinoma, gastrin-positive cells were found in 2 cases, and somatostatin-positive cells were found in 2 cases. 3) We concluded that, the endocrine cells are more frequently observed in the well differentiated gastric carcinoma than poorly differentiated carcinoma tissue. In summary, gastric carcinomas are supposed to arise from the totipotent stem cells of endoderm origin, and they have multidirectional property of differentiation into both endocrine and nonendocrine cells. Most of them differentiate into nonendocrine cells and only a few of them differentiate into endocrine cells.

This study was conducted to invetigate the effect of high-dose steroid administration on adipogenesis and secretion of PAI-1 in rat. Sixty healthy Wistar rats were divided into three groups. Group A consisted of 20 control animals received 5 ml/kg isotonic saline for 1 weeks. Group B consisted of 20 animals received 10 ml/kg of methylprednisolone intraperitoeally for 1 week. Group C comprized 20 animals received 10 ml/kg of methylprednisolone intraperitoneally for 1 week. After the completionof treatment, blood sampling was performed for measurenement of PAI-1 and the animale were sacrificed for histopathologic examination and immunohistochemical study. The PAI-1 protein expressin of femoral heads were evaluated with Western-blotting. Blood level of PAI-1 increased significantly in high-dose steroid treated group(Group B and C) compared to control group. In histopathologic examination, significant fat morrow conversion, fat cell hypertrophy and fat cyst formation were observed in high-dose steroid treated group. Immunohistochemically, PAi-1 expression was sprominent in the fat cells. Protein expression of PAI-1 of femoral heads increased significantly in highdose steroid treated group compared to control group. In lights of above results, it is postulated that increased secretion of PAI-1 from fat cells could play a major role in the pathogenesis of osteonecrosis of the femoral head in rats treated with high-dose steroid.

Candida albicans is the most common cause of infectious esophagitis and usually is an opportunistic infection in immunocompromised patients. Dysphagia and odynophagia are the usual presenting complaints and, importantly, oral lesions are absent in 50 percent of patients. The role of gastrointestinal endoscopy in diagnosing fungal infections of the esophagus is primary. It is the most definitive and often the only method of detecting esophageal candidiasis. Accurate endoscopic diagnosis by biopsy or brushing leads to the initiation nf effective therapy. We have experienced a case of esophageal candidiasis in an 11-year-old girl who was immunologically normal and whose main symptoms were epigastric abdominal pain and nausea for 4 months. The endoscopic and pathologic findings of esophageal candidiasis were presented.
