Superior mesenteric artery thrombosis usually occurs in an area of severe atherosclerotic narrowing, most often at the origin of the superior mesenteric artery. On angiography, the absence of collateral vessels or the presence of collaterals with inadequate filling of the superior mesenteric artery indicates an acute occlusion and demands prompt intervention. A 44-year-old man presented with epigastric and right upper quadrant pain after eating. Computed tomography and angiography showed superior mesenteric artery thrombosis. After treating with intra-arterial infusion of urokinase and intraluminal stent insertion, the patient showed clinical improvement and near complete resolution of superior mesenteric artery thrombosis. Thus, direct infusion of urokinase into the superior mesenteric artery and angioplasty with stenting for treatment of superior mesenteric artery thrombosis can be the alternative to surgery in selected patients with superior mesenteric artery thrombosis.

원발성 세균성 복막염 진단에 있어서 혈액 배양 배지를 이용한 복수 배양법의 유용성
이명래(Myung Rae Lee),전재윤(Jae Yoon Chon),문영명(Young Myoung Moon),박인서(In Suh Park),이경원(Kyung Won Lee) 대한소화기학회 1995 대한소화기학회지 Vol.27 No.6
Background/Aims: Spontaneous bacterial peritonitis(SBP) is a serious and frequently fata1 compli- cation in cirrhotics, therefore earlier detection and earlier institution of appropriate treatment is crucial for good result. However, the conventional method of ascitic tluid culture has a low sensitivity in detecting causative organism of SBP. Methods: We have compared the sensitivity of the conventional method to the bedside inoculation of ascites into blood culture media. Two kinds of ascites culture methods were compared in cirrhotic patients with spontaneous bacterial peritoni- tis: 1) conventional(on blood agar, MacConkey agar, thioglycolate broth, and phenylethanol blood agar) and 2) blood culture media method(inoculation of each S mL of ascites into one 30-mL tryptic soy broth bottle and one30-mL thioglycolate broth bottle at the patients bedside. Results: In a 55-month period, 67 episodes of SBP in 61 cirrhotic patients were examined using simultane- ous both culture methods. The conventional method grew bacteria in 22 episodes(32.8%), whereas the blood culture media method grew in 55 episodes(82.1%), which showed a significantly higher sensitivity(p0.005). The organisms most frequently isolated in ascitic fluids in this study were aerobic gram-negative bacteria(88.37o), among them E. coli was the most most common pathogen comprising 55.0% of total isolates. The conventional method grew five species of organism whereas the b]ood culture media did eleven species. Most of E. coli were susceptible to amino- glycosides, third generation cephalosporins, aztreonam, and ofloxacin, but resistant to ampicil]in. Conclusions: It is suggested that the inoculation of ascitic fluid to a blood culture media is more sensitive than the conventional method and shou]d be routinely used for ascitic fluid culture in cirrhotic patients.

Objectives: It has been known that excessive iron promote the growth of cancer cells aad suggested that iron oversupply in cancer patients may enhance tumor growth and adversely affect cancer therapy and that desferoxamine (DFO) as a iron chelating agent may have a place in anticancer agents, which acts as a potent inhibitor of DNA synthesis via inhibition of the ribonucleotide reductase. However there have been no reports on the combined effect of DFO with other chemotherapeutics in vitro, This study was done to answer the questions: Does DFO inhibit the growth of cultured hepatoma cells? and Does the combination of DFO and chemotherapeutic agents have a synergistic effect on inhibition of tumor growth? Methods: Using PLC/PRF/5 and Hep G2 cells as hepatoma cells and normal diploid cells of WI-38 as control, the MTT assay was performed for evaluation of the cytotoxicity and an isobologram method to analyze the combined effects of DFO and other chemotherapeutic agents. Results: 1) The hepatoma cells grew faster in an iron-enriched medium than in the medium without additional iron supplementation but the normal diploid cells of WI-38 did not. 2) The 50% inhibitory concentrations (IC50) on PLC/ PRF/5 and Hep 62 cells were 75.1 and 29.1 ㎍/ml, respectively. But the growth of WI-38 was not inhibited below 74.4% with even 200 ㎍/ml of DFO. 3) On both hepatoma cells, the growth inhibitory effects of DFO were reversed with simultaneous administration of stoichiometric doses of ferric citrate. 4) Adriamycin (ADR), 5-fluorouracil (5-FU) and cisplatin (DDP) inhibited the growth of all 3 cell lines, but larger doses were required to inhibit the WI-38 to obtain the same effect. 5) When DFO was combined with chemotherapeutic agents, a marked synergistic effect was observed with the combination of DFO and 5-FU on PLC/PRF/5 cells. The synergistic effect was also noted in Hep G2 cells with all three combinations of DFO-ADR, DFO-5-FU and DFO-DDP. Conclusion: Iron oversupply may enhance the hepatoma growth and this should be taken into consideration treating patients with hepatoma. And the antitumor effect of DFO and its synergistic effect with other chemotherapeutic agents may suggest that iron chelator like the DFO may be a useful treatment for patients with hepatoma in conjuction with other anticancer drugs.

Gastric xanthoma which is not a true neoplasm and clinically insignificant consists of the small yellowish lesion of the gastric mucosa, frequently of multiple occurrence. Histologically the lesion shows chronic superficial gastritis with intestinal metaplasia and occasional collections of foam cells within the lamina propria. Electron microscopically. the xanthoma, cells are composed of. lipid-laden histiocytes with. many autophagocytic Iysosomes surrounding the cytoplasmic lipid vacuoles. Many residual bodies are also noted. The pathogenesis of the gastric xanthoma is obscure, however it is thought that a previous focal lesion of the gastric mucosa may have been a factor. One case of gastric xanthoma is reported here and a brief review of literature is also made.

The question of whether or not ethanol-induced liver injury is related to or accompanied by lipid peroxidation has been a subject of controversy. Short-term ethanol administration was shown by some to produce hepatic lipid peroxidation in rats, but very large doses of ethaol had to be used. Furthermore, some investigators failed to confirm these effects of ethanol. Fewer studies have explored the relationship between alcohol consumption and lipid peroxidation. In order to study this question and clarify the role of oxygen derived free radicals and lipid peroxidation of the RBC in inducing the alcoholic liver diseases, we measured the thiobarbituric acid reactivities in normal controls and patients with alcoholic liver disease. The subjects were divided into three groups according to the liver function tests and the amounts of alcohol drinking: group I-normal controls, group II-cases showing normal liver function test in spite of frequent alcohol drinking over 3 days per week and 45 g alcohol per one time, group III-patients with alcoholic liver disaesae, drinking alcohol over 4 times per week. The thiobarbituric acid reactive substances were measured as a marker of lipid peroxidation by the method of Uchiyama and Mihara. The colorimetric method was used by a measurment of malonyldialdehyde [MDA, nmole/ml (packed cells)] concentration. The results were as follows; (continue...)
