Background: Urinary kidney injury molecule-1 (KIM-1) is an early and sensitivebiomarker of acute kidney injury, but it is unclear if it is a biomarker of chronicglomerulonephritis. We evaluated whether urinary KIM-1 levels in patients withimmunoglobulin A (IgA) nephropathy can be a marker to reflect clinicopathologicalseverity and predict the prognosis. Methods: We measured urinary KIM-1 levels in 40 patients (15 males; mean age36.6712.9 years) with IgA nephropathy and 10 healthy people (5 males; mean age37.379.6 years) as controls. The correlation of urinary KIM-1 levels with patients’clinical parameters, histological grades, and follow-up data were analyzed using themodified H. S. Lee grading system and tubulointerstitial change scores. Results: Urinary KIM-1 levels were higher in patients with IgA nephropathy thanhealthy controls (P¼0.001). Univariate and multivariate regression analyses showedthat urinary KIM-1 levels had a direct correlation with H. S. Lee grade andtubulointerstitial inflammation (P¼0.004 and P¼0.011, respectively). Conclusion: In patients with IgA nephropathy, urinary KIM-1 has a significantcorrelation with histopathologic severity.

A fourteen-month-old intact female Poodle was referred to the Veterinary Teaching Hospital, College of Veterinary Medicine, Chungnam National University. The patient was presented with history of vomiting, inappetence, ataxia, insomnia, tachypnea and convulsion for 5 days. Biochemical examination revealed BUN (254.2 mg/dl), creatinine (9.22 mg/dl) and phosphate (14 mg/dl). Epithelial cells of urinary tract, neutrophils, macrophages, a large number of gram negative and smaller number of gram positive bacteria were presented on urine test. Ultrasonographic findings show hyperechogenic kidney and indistinguishableness of renal cortex and medulla. Based on the results of examination described above, this case was diagnosed as acute renal failure with interstitial nephritis by urinary tract infection (UTI). Treatments with fluids therapy, diuretics, and peritoneal dialysis during hospitalization showed good results with no clinical signs.

Asymmetric polyimide(6FDA-p-TeMPD) membranes were prepared by a wet phase inversion method. The polyimide used in the preparation of membranes was synthesized by chemical imidization method of hexafluoroisopropylidene-2,2-bisphthalic anhydride (6FDA) and 2,3,5,6-tetramethy-1-1,4-phenylenediamine(p-TeMPD). The change of the membrane morphology were investigated with polymer concentration, sort of solvent and the differences of solubility parameter in polymer, solvent and nonsolvent. The micro-voids disappeared as the concentration of polymer increased, indicating that the exchange between solvent and nonsolvent was prohibited due to increasing of polymer concentration. The difference of solubility parameter plays a very important role in determining the membrane morphology and performance. In accordance with solubility parameter difference, the morphology of the membrane was shown in two aspects: (1) a sponge-type in the delayed liquid-liquid phase separation process; (2) a finger-type in the instantaneous liquid-liquid phase separation processes. According to the sort of the nonsolvents used to the formation of the membranes, oxygen permeability coefficient(P_O2) was the order of IPA> MeOH> H_2O> EtOH, and selectivity(P_O2/P_N2) was the order of MeOH> H_2O> EtOH> IPA. Especially, in the system of PI/DMAc/MeOH, the membrane which had the remarkable gas separation performance was produced. Oxygen permeability coefficient(P_O2) and selectivity(P_O2/P_N2) in the membrane was 106 Barrer and 4.21, respectively.

Atherosclerosis is now viewed as an inflammatory disease of the vascular system. Expression of several chemokines, including monocyte chemoattractant protein(MCP)-1, MCP-4, RANTES(regulated on activation normal T-cell expressed and secreted), and interleukin-8(IL-8) are increased in human atherosclerotic plaques compared with normal vessels. They are involved in the pathogenesis of atherosclerosis and plaque rupture by activating and directing leukocytes into the atherosclerotic lesions. However, some are involved in homeostatic functions such as normal leukocyte traffic and growth regulation. SDF-la is a multi-functional cytokine that is involved in myelogenesis, hematopoiesis, angiogenesis and injured gastric mucosal regeneration in the gastric ulcer patient. SDF-la is recently shown to be highly expressed in atherosclerotic plaques and a potent platelet agonist. At least in high concentrations, SDF-la may mediate antiinflammatory and matrix stabilizing effects in unstable angina. Many studies are going on to know the function of SDF-la in coronary artery diseases. I investigated the difference of the plasma level of SDF-la between control group and coronary artery disease group. Total 75 subjects were enrolled. The diagnosis of coronary artery disease was confirmed in all patients by coronary angiography. Control subjects in this study were confirmed normal by coronary angiography. Clinical profile and risk factors were also reviewed. Control subjects in this study were 27 (M=10, F=17). Plasma for the study was collected before the angiography and centrifuged. SDF-la analysis was performed by ELISA. Plasma level of SDF-la is significantly increased in patients with stable angina(n=20) and unstable angina group(n=28) compared with healthy control group(n=27). the risk factors do not influence the plasma level of SDF-la in coronary artery diseases. In this study, plasma level of SDF-la is increased in patients with stable angina and unstable angina groups compared with healthy control group(P<0.05). the risk factors do not influence the plasma level of SDF-la in coronary artery diseases.

Inspite of possible effects for emesis following chemotherapy including cisplatin, nausea and vomiting are the most unpleasant side effects of cancer chemotherapy. None of the currently available antiemetic agents is entirely effective preventing emesis. Ondansetron, a 5-HT(5-hydroxytryptamine)_(3) receptor antagonist, has been shown to be effective antiemetic agent in the control of cisplatin induced emesis. Twenty solid tumor patients who are scheduled to receive cisplatin containing combination chemotherapy participated in a prospectively randomized study to compare the antiemetic efficacy and safety of ondansetron and metoclopramide. Ondansetron was given in dose of 8mg intravenous 30min before cisplatin and then 4hours and 8hours after cisplatin on day 1, and Ⅰ.Ⅴ. every 8hours from day 2 to 5. In the metoclopramide group, metoclopramide was given in dose of 2 ㎎/㎏ intravenous every 8hours from day 1 to 5. The control of emesis was graded in the following way : complete response, no vomiting : major response, 1-2 emetic episodes : minor response, 3-5 emetic episodes : failure, above 5 emetic episodes. Complete or major response of emesis was achieved 10 of 12(83.2%) patients receiving ondansetron and in 5 of 8(62.5%) patients receiving metoclopramide, but effectiveness was not significantly different. Ondansetron was at least as effective as metoclopramide therapy in controlling cisplatin induced emesis. Side effects in ondansetron was less than in Metoclopramide.

Eagle's syndrome is the term given to symtomatic elogation of the styloid process or mineralization of the stylohyoid or stylomandibular ligament. Since ossification of stylohyoid ligament at cadeva was fist described by De Manchetics in 1652 and Weinlecher described clinical symptom which produced by elongated styloid process and osteotomy of styloid process in 1872, Clinical symptom which include sensation of a foreign body on the pharynx, dysphagai, dysphonia, referred pain, and mouth opening disturbance was termed by Eagle as Eagle's syndrome. then, case reports of Eagle's syndrome are presented. in these cases, the patient's chief complaints included periauricular radiating pain, mouth opening disturbance, foreign body sensation, dysphagia, tenderness on the neck. Through vairous X-ray examination and palpation of tonsillar fossa, elongted styloid process were confirmed. Under the general anesthesia there were successfully removed out via transoral approach technique, described by Eagle. after resented styloid process, they were freed from the symptoms without further complication. Therefor we reported these cases treated by surgical resection of styloid process with good results.

질량분석기로 사용되는 폴 트랩 내에서 보다 실제적인 이온운동을 예측해내기 위하여 약 2천 개의 다중입자의 궤적에 대한 계산을 실시하였다. 보다 정확한 질량 분석스펙트럼을 얻기 위하여 충돌확률에 대한 보다 정확하고 실질적인 함수 값을 도입하였다. 계산된 전산시늉의 결과들로부터 특히 작은 질량의 영역에 대한 분석을 할 경우 본 논문에서 제시된 바와 같이 매우 정확한 충돌확률이 고려되어야 함을 확인할 수 있었다. To predict the practical characteristics of ion motion in the paul trap as a mass spectrometer, the ion trajectories of the multi-particle(over than 2000 particles) were calculated. In order to expect more practical mass spectrum, the exact expressions for the collision probability was adopted. From the simulation result, we found that the exact collision probability has to be considered to analyze the materials existed in the low mass region.

정신분열병과 Neurotensin 수용체 유전자 다형성의 연합 연구

이유상,김형배,한진희,채영규,이정식,이혜순,주연호,김형섭,최인근,양병환 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.6

연구목적: Neurotensin(NT)은 NT수용체와 결합하여 그 효과를 나타내는 neuromodulator 혹은 neurotransmitter로서 대뇌에서 도파민의 분비를 조절하는데 중요한 역할을 한다. 근래의 연구에 의하면 NT와 그 수용체는 대뇌에서 항정신병 약물의 효과를 매개하는 것으로 생각되고 있으며 약물치료를 받지 않은 정신분열병 환자의 뇌척수액에서 NT의 양이 적으로 보고되고 있어 이들은 정신분열병과 깊은 관련을 가지고 있을 것으로 추정된다. 최근 NT수용체의 유전자의 3`인접영역에서 정보가치가 높은 4 염기반복 다형성이 발견되어 이를 유전 표지자로 하여 정신분열병과의 연합을 알아보았다. 방 법: 서로 혈연관계에 있지 않은 정신분열병 환자 120명(남자 91명, 여자 29명)과 정상 대조군 106명(남자 84명, 여자 22명)을 대상으로 하였다. PANSS를 사용하여 양성 및 음성을 알아보았다. 말초혈액에서 DNA를 분리한 후에 중합효소연쇄반응을 사용하여 3`인접영역에 있는 4 염기 반복 다형성을 증폭하였고 silver staining한 후에 유전자형을 관찰하였다. chi-square 검증과 Bonferroni`s correction을 사용하여 환자군과 정상 대조군간의 대립유전자 빈도의 차이를 알아보았다. 또한 양성 및 음성 환자군으로 나누어 차이를 알아보았다. 결 과: 총 23개의 대립유전자가 관찰되었으며, 399bp의 대립유전자(A10)의 빈도가 환자군보다 정상대조군에서 통계적으로 유의하게 높았다(χ²=16.49, df=1, p<0.001). 음성 정신분열병 환자군과 정상대조군 사이의 비교에서는 정상대조군의 A10의 빈도가 환자군보다 유의하게 높았다(χ²=21.33, df=1, p<0.001). 성별 비교에서 남자 정신분열병 환자군은 대조군에 비하여 A10의 분포가 유의하게 적었다. (χ²=13.71, df=1, p<0.001) 결 론: NT 수용체 유전자와 정신분열병사이에 음성연합이 관찰되었다. NT 수용체 유전자가 일부 정신분열병의 발병과정에서 확실하지는 않지만 어떤 종류의 보호기능을 할 수도 있다는 것을 암시한다. Objectives: Neurotensin(NT), of which functions are evoked by its interaction with neurotensin receptors(NTR), coexists with mesolimbic dopamine and regulates endogenous dopamine release. Recent studies have shown that NT with NTR exerts neuroleptic-like activity within the central nervous system and may play an important role in the pathogenesis and in the treatment of schizophrenia. We have examined the gentic association between schizophrenia and tetranucleotide repeat polymorphism in the 3-flanking region of the NTR gene to investigate the possible contribution of the NTR gene to the schizophrenia susceptibility. Methods: Among 23 alleles identified, the subjects were 120 patients(male 91, female 29)with schizophrenia and 106 normal healthy controls(male 84, female 22). They were unrelated native Korean. PANSS was used to determine positive or negative subgroup in the schizophrenic patients. Using polymerase chain reaction and polyacrylamide gel electrophoresis, tetranucleotide repeat polymorphism(CCTT and CTT) in the 3`-flanking region of NTR gene was observed. For a comparison of NTR gene`s allelic frequencies between patients with schizophrenia and normal healthy controls, chi-square test and Bonferroni`s correction was performed. Results: The frequency of A10 allele(base pair size=399)was significantly higher in normal healthy controls than schizophrenia(χ²=16.4902, df=1, p<.000). In the comparison between schizophrenic patients with negative symptoms and normal controls, the frequency of A10 allele was significantly higher in normal healthy control subjects than patients with schizophrenia(χ²=21.33, df=1, p<0.001). In the case of male, the frequency of A10 allele of schizophrenia was significantly higher than normal controls(χ²=13.71, df=1, p<0.001). Conclusions: NTR gene was negatively associated with schizophrenia. NTR gene`s tetranucleotide repeat polymorphism may provide some protective function against schizophrenia.
