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.

파로부터 acid phosphatase를 Sepharcyl S-200 gel filtration과 CM-Sepharose CL-6B ion exchange chromatography 를 이용하여 부분정제하였다. p-Ni-trophenyl phosphate를 기질로 사용했을 경우에 최적pH는 5.5, 최적온도는 60℃였다. 효소의 활성화 에너지는 4.86kcal/mole이었다. 효소는 pH6.0에서 가장 안정하였으며, 50℃이하에서 대체로 안정하였다. 효소는 p-nitrophenyl phosphate를 기질로 가장 잘 이용하였으며, 5'-IMP와 5'-GMP는 기질로 거의 이용하지 못하였다. 효소는 p-nitrophenyl phosphate를 기질로 했을 경우에 ??값이 0.87mM이었다. Cr+++, Zn++, Cu++ 이온은 효소의 활성을 저해하였으며, 또한 molybdate와 metavandate 이온이 효소의 활성을 저해하였다. 그리고, NaCl의 농도가 높을수록 효소의 활성을 저해하였다. Acid phosphatase (EC 3.1.3.2) from welsh onion was partially purified by Sephacryl S-200 gel filtration and CM-Sepharose CL-6B ion exchange chromatography. The optimum pH and temperature of acid phosphatase from green onion were pH 5.5 and 60℃, respectively. The enzyme was the most stable at pH 6.0 and unstable above pH 9.0. The activation energy of the enzyme was determined to be 4.86 kcaL/mole. The enzyme utilized p-nitrophenyl phosphate most as a best substrate among tested possible substrates, while 5'-GMP and 5'-IMP were poor substrates for the enzyme. ?? of the enzyme with p-nitrophenyl phosphate as a substrate was identified as 0.87 mM. Among metal ions and inhibitors tested, Cr+++, Zn++, Cu++, molybdate and metavanadate ions inhibited the enzyme reaction drastically.

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.

에로스, 그리고 놀이하는 시인

김석환 한국현대문예비평학회 2003 한국문예비평연구 Vol.- No.12

This paper takes a psycho-analytical approach to delineating the relationship between eros and poetry. The art of poetry writing is a creative process in which the poets engage in an introspection of the eros, which lies latent within their psyche, and consequently portray the anguish derived from the repressed eros. This is a meaningful task to reaffirm their true self and life force. In poetry, the eros invariably manifests itself in the form of sexual desires and material desires, revealing the pleasure-centered self-destructive tendencies of modern. society. However, poets refrain from dealing with eros in a direct manner but rather rely on the creative play of poetry writing to actively pursue a world of new values. This facet of the creative process also serves as an indicator of the proper form and function of poetry. In other words, the true poetic play seeks to create a new symbolic order that can transcend the anguish born of eros and thereby illuminate a world of higher values.

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.

김원율,이상래,안지영,안성훈,류석용,김경환,김홍용 대한응급의학회 2000 대한응급의학회지 Vol.11 No.3

Background: In emergency department, there are many drunken patients with various emergency medical situations. In these patients, evaluation and management of the medical problems are delayed from time to time because of the uncooperative nature of the patients and because of consciousness and sensory changes. A precise evaluation can only be obtained when the patients become sober. For this purpose, most clinicians start IV fluid loading. This study was carried out to evaluate the effect of IV fluid(normal saline and glucose solution) on the rate of ethanol clearance in such patients Methods: Ten volunteers(healthy males in their twenties and with a Michigan alcohol screening test below 4) were enrolled in this study. Alcohol intake was restricted to at least 48 hours before the test and food intake to at least 4 hours. For the test, A predetermined dose of ethanol(1 gm/kg) was given to the volunteers. Each volunteer was tested on three consecutive times with 3 or more days interval for alcohol wash out period . On the lst day, the volunteers received ethanol only per os. On the second day, they received ethanol and a liter of IV 10% dextrose solution. Each day, blood was drawn from the antecubital vein to measure the ethanol level at the time of ethanol ingestion and at 0.5, 1, 1.5, 2, 3, 4, 5 and 6 hours after ingestion. The repeated measure ANOVA test was used for the statistical analysis. Results: The difference in the blood ethanol level between the 3 test was F=1.7, p=0.184 and the difference corrected by the time factor was F=0.32, and p=0.985. Conclusion: There was no significant difference in the blood ethanol level between the tests. In conclusion, the IV normal saline or glucose solution does not accelerate ethanol clearance in suffering
