BACKGROUND: Increasing degrees of medullary hyperemia induced by ischemia reperfusion injury were associated with renal dysfunction. A possible mechanism may be that ischemia causes alterations in the structure and function of vascular membranes which leads to an aggregation of red blood cells in the medullary vessel. It has been shown that heparin prevents postischemic endothelial cell dysfunction. Aim of this study was to evaluate heparin effects on renal hyperemia induced by ischemia reperfusion injury. METHOD: In this study, fifteen rabbits were randomized to either heparin treatment group(500 IU/kg IV bolus 10 minutes before renal artery occlusion, n=8) or control group(n=7). One side kidney underwent 60 minutes ischemia only by clamping renal pedicle and after that kidney tissue sample was obtained for histologic evaluation. The other side of kidney were permitted 60 minutes ischemia following 60 minutes reperfusion and after that kidney tissue sample was obtained for histologic evaluation. RESULTS: There was significant difference in the degree of congestion(2.6+/-0.2 vs 1.1+/-0.3, P<0.05) between outer medulla of control and heparin treatment group. CONCLUSION: Heparin significantly attenuated outer medullary congestion induced ischemic injury.

This study investigated the effects of soyoligosaccharide consumption on lipid profile of plasma, liver and feces and immune responses in Sprague-Dawley male rats. Sixty male Sprague-Dawley rats 4-wk-old were provided the soyoligosaccharide containing diets for 4 weeks (0, 100 g/kg diet); each of these diets was supplemented with either 70 or 200 g fat/kg diet, giving a total of 4 experimental groups. The effect of weight reduction was most significantly observed in the group fed low fat and soyoligosacchairde diet. The plasma total lipid and cholesterol contents were not changed by either fat proportion or soyoligosaccharide supplementation in the diets. Also the plasma triglyceride lowering effect by soyoligosaccharide was not observed in rats fed either low fat or high fat diet. However, the significant decrease in TG contents was found with rats fed high fat diets compared to the control/no soyoligosaccharide diet. Elevation of plasma LDL-cholesterol and reduction of HDL-cholesterol by feeding high fat diet was not altered by supplementing soyoligosaccharide. This was also applied to the liver lipid profiles. The significant increases in liver total lipid, triglycerides and cholesterol by high fat diet was not abolished by feeding soyoligosaccharide. However, the desirable effects of feeding soyoligosaccharide were found with total lipid and cholesterol excretion through feces in rats fed high fat diets. Immune organ weights and spleen cell proliferations did not affected by experimental diets. These results demonstrated that soyoligosaccharide intakes increased the lipid output via feces, especially in rats fed the high fat diet, but more researches are needed on immune responses.

OBJECTIVE: Appearance of DSM-IV has influenced greatly on the nosological classification of mental disorder, not considered as revised one of DSM-III-R but a new criteria. DIS-IV has been developed after revision of DIS-III in consideration of various changes in DSM-IV. This study is to develop and validate the DIS-IV, Korean version to activate Korean psychiatric research much more and to modivate more frequent international collaborative study. METHOD: Translation committee produced DIS-IV, Korean version through all the procedures of translation, back-translation, confirmation of retained original meaning of the English version, adaptation to Korean linguistic usage and preliminary study. Four medical students were trained during DIS-IV training course that retained the same contents and methods as of Washington University. Inter-rater reliability was measured by comparison between two diagnoses made from two interviewer who rated one patient at the same time. Procedural validity was measured by comparison between lay-interviewer's diagnosis and psychiatrist's diagnosis which were made after independent DIS-IV using interview. Subjects were 124 patients who were being treated at two University Hospital and National Forensic Psychiatric Hospital between January, 2000 and August, 2000. RESULTS: Average kappa value of inter-rater reliability was 0.74. Diagnoses showing over 0.7 in kappa value were bipolar I disorder, generalized anxiety disorder, depressive disorder, obsessive-compulsive disorder, oppositional defiant disorder, pain disorder, pathological gambling, post-traumatic stress disorder, specific phobia and almost all substance use disorder or substance- related disorder. Procedural validity, that compared lay-interviewer's diagnosis and psychiatrist's diagnosis, were as follows;For all diagnoses, sensitivity, specificity and kappa were 67.6%, 98.3% and 0.69. For diagnoses of substance use disorder or substance- related disorder, sensitivity, specificity and kappa were 79%, 98% and 0.77. For other diagnoses except substance use disorder or substance- related disorder, sensitivity, specificity and kappa were 60.5%, 98% and 0.64. This results are almost at the same level as that of Robins and her colleagues who first reported reliability and validity of DIS. CONCLUSION: We think that DIS-IV, Korean version has higher reliability and validity. It is very important that diagnoses of substance use disorder and substance-related disorder can be made reliably and validly by this instrument. We expect that it can help to improve diagnosability of mental disorder, activate clinical research and increase international scientific communication.

Behcet's disease is a multisystem disorder characterized by oral and genital ulcers, uveitis, and skin lesions. Renal involvement has rarely been observed in Behcet's disease. However, pathological reports have revealed various lesions, especially, amyloidosis, focal and segmental glomerulonephritis with crescents, and IgA nephropathy. A 49-year old female with Behcet's disease was admitted to evaluate proteinuria and microscopic hematuria, and renal biopsy showed IgA nephropathy (subclass V). Immunohistology revealed mesangial deposits of IgA and staining for C3. We report a case of IgA nephropathy which was diagnosed by renal biopsy in a patient with Behcet's disease.

PURPOSE: We investigated the efficacy of ketoconazole and estramustine before chemotherapy for treating patients with progressive castration-resistant prostate cancer (CRPC) after anti-androgen withdrawal syndrome. MATERIALS AND METHODS: Eighty-four patients who were diagnosed with CRPC and were treated between 2005 and 2009 were included. Thirty-nine patients were treated with 600 mg of ketoconazole and 10 mg of prednisolone per day (group I), and 45 patients were treated with 560 mg of estramustine per day (group II). The prostate-specific antigen (PSA) response, progression-free survival, and side effects were compared. RESULTS: The median age of the patients, PSA level, and follow-up period were 72 years, 48.5 ng/ml, and 4 months (range, 1 to 29 months), respectively. The overall PSA response rate was 35.7%, and the PSA response rates were 33.3% for group I and 37.8% for group II (p=0.672). The median progression-free survival times were 8 months (95% confidence interval [CI] 5.9-10.1) overall, 5 months (95% CI 1.6-8.3) in group I, and 8 months (95% CI 5.9-10.0) in group II (p=0.282). The most common complications in groups I and II were nausea and vomiting (51.3%) and anemia (77.8%), respectively. Nausea and vomiting and hepatotoxicity were observed more often in group I, and gynecomastia, neutropenia, and anemia were observed more often in group II. The toxicities of each adverse effect were < or =grade 2. CONCLUSIONS: With a resultant PSA decline and mild adverse effects, both ketoconazole and estramustine are worth consideration as treatment options for progressive CRPC patients after primary hormonal therapy.

Systemic lupus erythematosus is a disease of unknown cause which involves various organs and primary involvement of urinary bladder is very rare. We experienced a case of a female patient with SLE and urologic manifestations (interstitial cystitis, hydroureters and hydronephrosis), which were resolved spontaneously without any immunosuppressive therapy. There was no significant correlation between clinical course and disease activity index.

BACKGROUND: Subarachnoid block is a widely used technique for cesarean section. To improve the quality of analgesia and prolong the duration of analgesia, addition of intrathecal opioids to local anesthetics has been encouraged. We compared the effects of sufentanil 2.5 microg and 5 microg, which were added to intrathecal hyperbaric bupivacaine. METHODS: We enrolled 105 full term parturients were randomly divided into 3 groups: Group 1 (control), Group 2 (sufentanil 2.5 microg), and Group 3 (sufentanil 5 microg). In every group, 0.5% heavy bupivacaine was added according to the adjusted dose regimen. We determined the maximum level of sensory block and motor block, the quality of intraoperative analgesia, the duration of effective analgesia and side effects. RESULTS: There were no significant differences among the 3 groups in the maximum level of the sensory block and motor block. Recovery rate of the sensory block, however, was significantly slower in Group 3 than Group 1. Quality of intraopertive analgesia, muscle relaxation, and duration of effective analgesia were enhanced by increasing the dosage of intrathecal sufentanil. Frequencies of hypotension, maximum sedation level, and pruritus were directly related to the dosage of intrathecal sufentanil, whereas nausea and vomiting occurred only in the groups using sufentanil. CONCLUSIONS: The addition of sufentanil 2.5 microg for spinal anesthesia provides adequate intraoperative analgesia and good postoperative analgesia with minimal adverse effects on the mother.

BACKGROUND AND PURPOSE: The National Institutes of Health Stroke Scale (NIHSS) score is known to be effective in predicting the likelihood of recovery after stroke. However, the baseline NIHSS score predicts long-term outcomes rather crudely because early changes in stroke scores may influence the stroke outcomes. Therefore, a precise prognostic algorithm or a cutoff point for predicting long-term outcomes based on data from serial NIHSS scores is needed. METHODS: We serially assessed 437 patients with acute symptomatic ischemic stroke within the middle cerebral artery territory who presented with nonlacunar stroke and were followed-up for at least 6 months after symptom onset. The NIHSS score was serially checked at 0, 1, 3, 7, and 14 days after admission. In all patients, the Barthel index (BI) and the modified Rankin Scale (mRS) score were checked, with a poor outcome defined as any of the following endpoints: death, modified mRS score of >3, or BI of <60. RESULTS: A marked neurological improvement or worsening (i.e., a change in the NIHSS score of at least 4) was seen in 13.5% or 5.5% of the patients, respectively, during the first 7 days after admission. About 25% of the 437 patients had poor long-term outcomes. Analysis of receiver operating characteristic curves showed that the NIHSS score at day 7 after admission was better for predicting poor long-term outcomes than was the baseline score (P=0.003). In addition, we analyzed the cutoff point of the 7th-day NIHSS score for predicting a poor outcome at 6 months after symptom onset. An NIHSS score of at least 6 at day 7 after admission predicted poor long-term outcomes with a sensitivity of 84% [95% confidence interval (CI), 76-90%], a specificity of 92% (95% CI, 88-94%), and positive and negative predictive values of 77% and 95%, respectively. A logistic regression analysis revealed that age, diffusion-weighted imaging lesion volume, stroke history, and 7th-day NIHSS score were independently associated with poor outcome. However, no score used in addition to the 7th-day NIHSS score improved the prediction of a poor outcome. CONCLUSIONS: An NIHSS score of at least 6 on day 7 after admission accurately forecasts a poor long-term outcome after stroke. Our data may be helpful in predicting the long-term prognosis as well as in making decisions regarding novel therapeutic applications in subacute-stroke trials.

Cases of self-inserted foreign bodies in the male urethra and urinary bladder are unusual. In most cases, the type of foreign body can be identified by taking a history or from radiological findings; sometimes, however, it is difficult to identify the foreign body because of decreased mental capacity of the patient or unknown radiological characteristics of the foreign body. We experienced a chronic alcoholic patient with septicemia and penile necrosis in whom a fragment of mirror glass had passed through the urethra into the bladder. The glass, 2 cm in length and 0.7 cm in diameter, was detected by cystoscopy and was removed by using a resectosope.
