Spontaneous retroperitoneal hemorrhage due to hemophilia A with impaired coagulopathy is very rare. Spontaneous retroperitoneal hemorrhage has been recorded as having originated from many retroperitoneal organs and blood vessels, and it may be due to local and/or systemic factors. In the majority of the patients, kidney and adrenal gland were the major site of hemorrhage. The systemic causes of spontaneous retroperitoneal hemorrhage are anticoagulation therapy and chronic hemodialysis. During the course of these treatments, hemorrhagic complications may occur at many site, including the retroperitoneal space. Blood dyscrasias including leukemia, polycythemia, sickle cell trait and hemophilia have been reported associated with spontaneous retroperitoneal hemorrhage. We report a case of spontaneous retroperitoneal hemorrhage occurred in a gemophilia A patient with brief review of literature

상처받은 주체의 치유, '몸'과 '세계'의 이중억압을 넘어서 : 『달력공장 공장장님 보세요』를 중심으로 본 김혜순의 시 세계

This study seeks to investigate the interplay between 'body' and 'object' in the poetry of Kim, Hye-Soon. In Kim's poems, the body is the source of interminable existential crises and also the basis for suffering. Futthermore, the outer world that the body occupies proves to be no less an aggressive threat to the subject. In an attempt to effectively overcome this 'double oppression,' Kim foregrounds both the inner and the outer sphere affecting the body. However, in terms of the inner sphere, the wounded subject fails to overcome the limits sets by the reality principle. Likewise, in terms of te outer sphere, the attempt at the pluralization of the subject is also doomed to failure, insofar as the process f convergence back to a singular self ultimately comes into play. In the end, the yoke of multiple oppression can only be surmounted by re-establishing the relationship between the wounded subject and the external savior.

Background: A hyperosmolar nonketotic state has been known to have a high mortality, and even now, despite this high mortality, only a few studies of this disease have been performed. We studied the prognostic factors for the hyperosmolar nonketotic state. Methods: We retrospectively studied the cases of 40 patients who were in a hypersomolar nonketotic state when admitted to Sanggye Paik Hospital during the 6-year Period from 1995 through 2000. We divided the hyperosmolar nonketotic patients into two groups, the complete recovery group and the incomplete recovery group, and compared the clinical features, the laboratory findings, and the precipitating factors between two groups. Results: 1) A total of 40 patients were studied: 24 in the complete recovery group and 16 patients in the incomplete recovery group. The mortality rate was 32.5%. 2) No significant statistical difference existed among the clinical features of the two groups, except for the sex(p<0.01). 3) Among the laboratory findings of both groups, analysis revealed that the effective osmolarity was significantly higher among those in the incomplete recovery group(p<0.01). Serum sodium concentration was also significantly higher among those in the incomplete recovery group(p<0.01). Serum creatinine was also significantly higher among those in the incomplete recovery group(p<0.05). Serum bicarbonate concentration, on the other hand, was significantly lower among those in that group(p<0.05).4) Infection was identified as the most common precipitating factor(62.5%). Among the precipitating factors of the two groups, there were significant statistical difference in pneumonia, UTI, and inappropriate glucose control. 5) A significant statistical difference existed among the initial level of consciousness of both groups(p<0.05). 6) The only significant independent factor responsible for prognosis of nonketotic hyperosmolar state patients was the sex. Conclusion: The sex was only significant independent prognostic factor of nonketotic hyperosmolar state patients.

Orotic acid 의 과잉 섭취는 지질대사의 이상으로 인한 간 장해를 야기시키는 것이 알려져있다. 특히 지방간 생성에 대하여 관심을 가지게 되어서 본 연구는 orotic acid에 의한 혈청, 腎臟및 肝臟의4 지질 농도에 미치는 영향에 대하여 검토하였다. 시판 분말 chow 식이에 orpotic acid 1% 첨가, 무첨가한 식이를 21일간 90g전후의 성장기 Spragud-Dawley 系 웅성 쥐에 급여하였다. 그 결과 orotic acid 1% 첨가 식이에서 혈청 cholesterol, triglyceride및 phospholipid 농도는 각각 5% 수준에서 유의하게 저하하였다. 肝臟의 triglyceride농도는 5% 수준에서 유의하게 저하하였다, Orotic acid 첨가 식이에서 肝臟중량은 증가한 반면 腎臟중량은 저하하였다. Orotic acid 1% 첨가한 군에서 肝臟및 腎臟의 phospholipid 조성에의 영향은 인정되지 않았으나, 腎臟의 lysophosphatidylcholine은 높은 증가율을 보였다. 肝臟 phospholipid와 비교하여 腎臟에서는 sphingomyeline phospphatidylethanolamin은 유의하게 높은 분포를 나타냈다. 腎臟 phospholipid의 지방산 조성중에서 linoleic acid(18:2)가 상승하고 arachidonic acid (20:4)가 감소하였다. It was generally known that over-ingestion of dietary orotic acid caused hepatic disorder by the lesion of fatty acid and cholesterol synthesis in rats. The present study was carried out to investigate the effects of dietary orotic acid on the lipid composition of serum. liver and kidney of rats. For the experiments rats were fed with commercialized chow powder diet in the presence or absence of 1% orotic acid. The prepared diets were fed to male rats (Sprague-Dawley strain. 90∼100g of body weight) for 21 days. According to the results, orotic acid treated group showed that each concentration of serum cholesterol, triglyceride and phospholipid was significantly decreased (p<0.05). The centration of liver triglyceride was significantly decreased (p<0.05). In the presence of 1% orotic acid, the weight of liver increased while that kidney decreased. The treatment of orotic acid seemed to have no effects on the phospholipid composition in liver and kidney, except the kidney lysophosphatidylcholine. In the comparison of the phospholipid composition between liver and kidney, the levels of sphingomyeline and phosphtidylethanolamine in the kidney were higher than those in the liver. Among the composition of fatty acid in kidney, the concentration of linoleic acid (18:2) was increased, and the concentration of arachidonic acid(20:4) was decreased with the addition of the orotic acid.

DNA回復에 미치는 Poly(ADP-ribose)의 影響에 관한 硏究

金碩煥,鮮于洋一 東亞大學校 1990 東亞論叢 Vol.27 No.1

Effects of 3-aminobenzamide(3-AB), a potent inhibitor of poly(ADP-ribose) polymerase, on DNA replication was determined in CHO cells treated with methyl methanesulfonate(MMS) or UV-light by alkaline s ucrose gradient sedimentation analysis. MMS has been thought to inhibit the replication intitiation in mammalian cells, but we could also observe the inhibitory effect on chain elongation in CHO cells. At low concentration of 3-AB, the rate of DNA replication was not inbibited but at high concentration was shown in dose dependent manner. When MMS-treated cells were subsquently exposed to 3-AB, additive ingibitory effects were brought out. this result may be due to increases of single stand breaks by 3-AB. In the case of treatment with UV-light and 3-AB, hihg concentration of 3-AB induced the additive inhibitory effect on DNA replication, but low concentration of 3-AB alleviated unexpectedly the inhibitory effects of UV-light alone.

Mercuric chloride, inorganic compound, is one of the most important drugs that has been used in the field of argriculture, antisyphilitica and anticeptics, but it is not used clinically at present. We have studied the effect of testosterone on the mercuric chlorideinduced nephrotoxicity. Renal lipid peroxide concentration of male rat treated with mercuric chloride was significantly increased in comparison with that of the female rat, it showed similar effects on testosterone pretreatment. Changes in renal catalase and glutathione peroxidase activities were not siginificantly different in testosterone-treated groups. But, renal xanthine oxidase and aldehyde oxidase activities of testrosterone-treated group given mercuric chloride significantly increased in comparison with that of the testosterone-treated alone. Animals treated with testosterone prior to mercuric chloride showed more severe damage on histological observations than those treated with testosterone only. Consequently, we suggest that the mercuric chloride-induced nephrotoxicity might be renal lipid peroxide generating enzyme system by testosterone.

Heat and mass transfer in the counter-current contact of an air stream and a thin falling liquid film was investigated in a flat-plate wetted wall column. In this study, temperature profiles of the gas phase were measured by micro-thermocouples and composition of gas samples was analyzed by a gas-chromatograph. Local Nusselt numbers were calculated from the temperature profiles. Taking into account the effect of various variables on heat and mass transfer, a new theoretical model was proposed. The model was used to analyze experimental data. Observed heat and diffusion fluxes were compared with theoretical values predicted by a laminar boundary layer theory with high mass transfer at the interface. Good agreement between data and predictions was obtained.
