Effect of anticancer drugs and desferrioxamine in combination with radiation on hepatoma cell lines

Several anticancer chemotherapeutic agents (5-fluorouracil, adriamycin and cisplatinum) and desferrioxamine, an iron chelator, were tested with regard to cytotoxicity and to the combined effect on radiation induced cell killing using two human hepatoma cell lines (HepG2 and PLC/PRF/5). Survival fractions were measured by quantitative colorimetric assay (MTT assay) and dose-response curves were plotted. MTT assay could be successfully used in the assessment of radiosensitivity in addition to chemosensitivity, because a good linear relationship between optical densities and cell numbers was observed and cells approached exponential growth for the first 7 days of culture when 5 x 10(3) or less cells were inoculated per well in our study. Steepness of the final slope (D0), width of the shoulder (D0) and the extrapolation number (n) of radiation survival curves were 1061.72 rad, 226.43 rad and 1.25 respectively in HepG2 and 1091.38 rad, 268.42 rad and 1.29 respectively in PLC/PRF/5. After combining anticancer chemotherapeutic agents and desferrioxamine with radiation, the widths of the shoulders were decreased whereas sensitizer enhancement ratios were increased as the concentration of drugs increased in both cell lines. These results suggest that neither anticancer chemotherapeutic agents nor desferrioxamine enhance cell killing induced by radiation alone, but suggested the possibility that they inhibit the repair of radiation damage.

Bougie Dilatation of a Patient with Esophageal Lye Stricture Fed with Gastrostomy Tube for 21 Years: A case report / 대한소화기내시경학회지

The patient was a 51 year-old woman suffering fraen dysphagia due to upper esoyhageal lye stricutue whieh had developed as a result of a suicide attempt 21 years ago. Shortly after that, she underwent feeding gastrostomy and has lived in the gastrostomy state for 2l years. After admission, she underwent a barium esophagoram which revealed a near total obstruction at the cricoid cartilage level. Bougie dilatation with American Dilation System was tried on day 3. But the spring tip marked guide wire which was to be used with the American Dilation System could not be passed through the stricuture. Therefore, we performed a bougie dilatation using angiographic guide wire M(H-AG-35in-150 cm) with success. On day 14, she underwent a barium esophagogram which revealed her improved condition, and she was discharged on day 16.

Hemostatic Effect of Endoscopic Local Injection of Hypertonic Saline - Epinephrine Solution in Peptic Ulcer Bleeding / 대한소화기내시경학회지

To date several agents have been used to achieve hemostasis in patients with bleeding peptic ulcers using endoscopic sclerotherapy techniques. In this study, the efficacy of endoscopic local injections of hypertonie saline-epinephrine(HS-E) solution, consisting of 9 volume of 3% sodium chloride and 1 volume of 1: 1000 epinephrine, on the base of the ulcer around bleeding vessel was assessed. During the period between April 1989 and July l992, 127 patients were admitted to the study. Ninety-six of these patients underwent endoscopic treatmeat(endoscopic treatment group), while the other 31 cases received conservative treatment only(conservative treatment group). (continue...)

Liver Involvement in Multiple Myeloma Proven by Peritoneoscopy

Liver involvement in multiple myeloma has been known to be common in autopsied series. However, since its clinical significance is uncertain yet, invasive procedure confirming plasma cell infiltration of the liver has been rarely performed. We report a case with multiple myeloma which had plasma cell infiltration of a liver. A peritoneoscopic biopsy of the liver for the purpose of disclosing the nature of the aggravating liver function in a carrier of the hepatitis B virus showed infiltration of lymphoreticular cell which were identified later as lambda-light chain producing primitive plasma cells by immunohistochemical stain.

Effect of polyadenylic.polyuridylic acid on cellular responses of peripheral blood mononuclear cells from patients with chronic active hepatitis B

We have investigated in vitro proliferative responses of peripheral blood mononuclear cells and productions of interferon-gamma and soluble interleukin-2 receptors by these cells from 6 patients with chronic active hepatitis B immediately before and 24 hours after a single intravenous injection of 100 mg of polyadenylic.polyuridylic acid. Cell proliferations were assessed by the technique of tritiated-thymidine incorporation and productions of interferon-gamma and soluble interleukin-2 receptors were measured by enzyme-linked immunosorbent assay. The administration of polyadenylic.polyuridylic acid to the patients has resulted in significant increases of in vitro proliferations of their peripheral blood mononuclear cells as well as productions of interferon-gamma by these cells. However, in vitro productions of soluble interleukin-2 receptors were not changed significantly. These results suggest that the enhanced cellular responses by polyadenylic.polyuridylic acid might be due to the increased sensitivity rather than the increased expression of cellular interleukin-2 receptor.

Gallbladder Ascariasis: A case report / 대한소화기내시경학회지

Migration of roundworms, Ascaris lumbricoies, into the biliary tract is a relatively common cause of biliary symptoms in endemic areas, but the number of reported gallbladder ascariasis was scanty even in these areas. Some diagnostic methods might provide suggestive informations, but there are no pathognomonic clinical features for biliary ascariasis, so it is discovered usually after surgical exploration, which is especially the case of gallbladder ascariasis. A young female patient with 4 months' history of right upper quadrant pain which did not respond to medical control and was aggravated recently, presented normal level of peripheral blood leukocyte count with no eosinophilia, normal liver function test, normal serum amylase level and subjectively no febrile sense. Abdominal ultrasonogram disclosed a long, thick, linear, non-motile echogenic structure, not accompanied by acoustic shadowing, within the gallbladder. The intra-and extra-hepatic bile ducts were not dilated and the pancreas was revealed as normal echogenecity and contoru. Endoscopic retrograde cholangiopancreatography was performed immediately thereafter, and it showed a thin linear filling defect in the gallbladder. Cholecystectomy was performed under the impression of gallbladder ascariasis. A mummified Ascaris lumbricoides was found in the lumen of the gallbladder. There was no stones and the histologic examination of the gallbladder revealed chronic cholecystitis.

Endoscopic Manometry of Pancreatic Duct Sphincter in Patients with Chronic Pancreatitis / 대한소화기내시경학회지

The orifice of duodenal papilla is only about 1 mm in diameter. As much as 2,000 ml of bile and pancreatic juice pass through its sphincter zone into the duodenum each day. Since the sphincter of Oddi regulates the flow of bile and pancreatic juice, a disorder of the sphincter can disturb the smooth outflow of bile and pancreatic juice and produce secondary abnormalities in the biliary tract or the exocrine pancreas.

A Case of Leimyomatosis Peritonealis Disseminata Combined with Advanced Gastric Cancer / 대한소화기내시경학회지

Leiomyomatosis peritonealis disseminata is a rare benign condition characterised by the occurrence of multiple leimyomas scatterred throughout the peritoneal cavity, giving the clinical impression of a wide spread malignant tumor. The histopathology of leiomyomatosis peritonealis disseminata is that of a benign leiomyoma, probably originating from the multipotent subcoelomic mesenchymal cells. Three cases with malignant transformation were described among previous reported fifty cases. Many of the early reports described the disorder in premenopausal women, and now the histogenesis is considered to be a metaplastic change by abnormal tissue response to the relatively or absolutely elevated female sex hormone. We report a case of leiomyomatosis peritonealis disseminata, which was diagnosed by multiple scattered submucosal and subseroal leimyomas of stomach, small bowel and colon, combined with advanced gastric cancer in a 58 years old man, Multiple submucosal tumors of the stomach combined with advanced gastric cancer were demonstrated by fibergastroscopy, upper gastrointestinal barium study and abdominal ultrasonography. During radical subtotal gastrectomy multiple submucosal and subserosal tumors of stomach, and subserosal tumors of small bowel and colon were observed and these tumors were confirmed as leiomyoma without malignant potential.

Cytomegalovirus (CMV) - associated Gastric Ulcer Proved by Dot - blot Hybridization / 대한소화기내시경학회지

In gastrointestinal tract CMV has been implicated in inducing mucosal inflammatory and ulcerative lesions. More recently, increasing number of patients with CMV-associated gut lesions have been reported primarily in immunocompromised patients or occasionally in normal hosts. The colon is the most common site of the infection, although it might occur in other gastrointestinal tract such as esophagus, stomach, duodenum and terminal ileum. The diagnosis of CMV infection can often be difficult and must await serological conversian or viral cultures. (continue...)

Gastric varices: diagnosis with duplex Doppler ultrasonography: a case report

The diagnosis of gastric varices may be difficult due to their anatomic location and morphology. In this abstract we describe a case of gastric varices, of which a duplex Doppler sonography was useful in the diagnosis, that was initially suggested as submucosal tumor of the stomach by barium studies and endoscopy.

ERCP in Acute Pancreatitis / 대한소화기내시경학회지

For many years ERCP has been contraindicated in acute pancreatitis. The injection of contrast medium. which may cause hyperamylasemia and occasionally an attack of acute pancreatitis even in normal indivisuals, was allowed only two to three weeks after subsidence of symptoms. Gallstone disease is one of the most common etilogical factors in pancreatitis and migration or impaction of gallstone in the ampulla of Vater causes pancreatitis. (continue...)

A Case of Herpes Esophagitis Confirmed by Electron Microscopic Findings / 대한소화기내시경학회지

Herpetic esophagitis is a rare disease occuring mostly ie immunocompromised and cancer patient. It is also documented as self-limiting esopbagitis in young healthy adults. We report here a 30- year-old immunocompetent male patient with esophageal ulceration. Heryetic esophagitis was diagnosed by characteristic endoscopic and microscopic findings. And the diagnosis was confirmed by electron microscopic appearance. This immunocompetent patient recovered spontaneously with symptomatic treatment only. And repeat endoscopy and histology confirmed absence of herpes infection.

Dilatation of Severe Corrosive Esophageal Stricture Guided by Right Coronary Artery Catheter / 대한소화기내시경학회지

Nonoperative dilatation techniques such as bougination, balloon dilatation, endoscopic laser therapy, and endoscopic electro-coagulation, have been applied to relieve dysphagia due to esophageal strictures, but the most widly used ia peroral dilatation once a guide wire has been passed under direct vision using a fiberoptic endoscope. Some cases of severe and curved esophageal strictures coutd'nt be introduced the conventional steel guide wire. We desecibe a method of cannulation of these difficult strictures guided by torque control angiographic catheter with radiogrphic control. A case of 18 year old man with severe corrosive esophageal stricture ingested HCl was successfully treated with esophageal dilatation with Savary-Gilliard dilator guided by Judkin's right coronary artery catheter.

A Case of Congenital Hepatic Fibrosis / 대한소화기내시경학회지

We experienced a case of congental hepatic fibrosis in a 21-year-old Korean male. He had frequent episodes of esophageal variceal bleeding. His liver and kidney functions were preserved. He had cystic lesions on both kidneys. A diagnosis of congenital hepatic fibrosis was made by an inferior venacavogram and peritoneoscopic liver biopsy. A Kobayashi operation was performed for esophageal varices. He had no more variceal bleeding and his general condition was good after operation.
