연구목적: 정신장애의 정확한 진단과 평가는 임상에서뿐만 아니라 신뢰성 있는 연구를 위해서도 매우 중요하다. Structured Clinical Interview for DSM-IV(SCID)는 임상전문가들이 사용하는 진단도구로서, 비교적 짧은 시간에 정확한 진단을 내릴 수 있다. 본 연구는 한국어판SCID를 개발하고 그 신뢰도를 평가하기 위해 수행되었다. 방법: 국문학자가 포함된 번역위원회를 통하여 연구용판 SCID를 번역한 후, 정신과 의사 2인과 임상심리학자 1인에게 한국어판SCID 실시방법을 교육시킨 뒤 한국어판SCID를 이용한 면담의 평가자간 신뢰도 (interrater reliability)를 검증하였다. 면담 대상은 1999년 2월에서 3월까지 2개 병원 정신과에 치료중인 환자 90명(남:41명, 여:29명)이었다. 결과: 현재 장애(current disorder) 평가에서 주요 우울장애, 기분부전장애, 정신분열병, 알코올 남용 및 의존, 기타 물질 남용 또는 의존, 여러 불안장애들 및 섭식장애 등과 같은 대부분 장애의 kappa값은 .70이상으로 매우 높았다. 그 이외의 양극성 장애, 망상장애, 광장공포증, 감별 불능 신체화 장애 및 건강염려증의 kappa값도 .69에서 .40사이로 수용할 수 있는 정도였다. 평생 장애(lifetime disorder)에서는 양극성 장애(k=.69)와 감별 불능 신체화장애(k=.59)를 제외한 다른 모든 장애의 kappa값이 .70이상이었다. K-SCID 면담시 Ⅰ축 질환에 대하여 흔하게 다중 진단이 내려졌으며, 평균 진단 수는 1.5∼1.7개로 나타났다. 결론: 한국어판 SCID는 신뢰도가 높은 진단도구로 생각되며, 향후 정신질환의 정확한 진단과 임상연구에 유용하게 사용될 수 있다. Objectives: Accurate diagnosis and assessment for psychiatric disorders is crucial for research, as well as for clinical practice. Structured Clinical Interview for DSM-Ⅳ(SCID-RV) is a less time-consumimg and more accurate structured diagnostic interview form. It can be used by clinical professions and is known for a reliable diagnostic tool. Present study was conducted to develop Korean version of SCID-RV and to test the inter-rater reliability. Methods: The authors have translated original SCID-RV into Korean, and revised in parallel with sociocultural background of Korea. Ninety patients from two psychiatric hospitals, both outpatient and inpatient, were interviewed and rated independently by three raters. Results: The kappa coefficients for most of illnesses, such as major depressive disorder, dysthymia, schizophrenia, alcohol abuse and dependency, anxiety disorder and eating disorder were excellent(>0.70) in the evaluation of current disorders. And the kappa coefficients for bipolar disorder, delusional disorder, agoraphobia, undifferentiated somatoform disorder, and hypochondriasis were acceptable(>0.40) in the evaluation of current disorders. In the evalua-tion of lifetime disorders, the concordant rates of all the diagnoses except bipolar disorder and undifferentiated somatoform disorder were excellent. Lack of hierarchy in DSM-Ⅳ allows for multiple Axis I diagnoses. Mean numbers of Axis I diagnoses per subject assigned by the three raters were 1.5-1.7. Conclusions: Our findings confirm that SCID-RV yields highly reliable diagnoses. SCID-RV is recommended for accurate diagnosis in clinical practice and research on psychiatric disorders.

해충저항성 Bacillus thuringiensis (Bt) 벼와 낙동벼의 비표적생물체인 물벼룩(Daphniamagna)에 대한 급성독성시험을 실시한 결과, 해충저항성 Bt벼의 48시간-EC50은 4,429.13 mg/L (95% 신뢰한계는 3908.130~5020.363 mg/L), 무영향 농도(NOEC)는 1,800 mg/L이었고, 낙동벼는 48시간-EC50은 2,889.56 mg/L (95% 신뢰한계는 1,073.407~6,854.321 mg/L), 무영향농도는 1,000 mg/L이었다. 처리기간 중 해충저항성 Bt벼와 낙동벼간의 급성독성에 영향을 미칠 수 있는 요인은 발생하지 않았다. Insect-resistant transgenic rice was developed by inserting the mCry1Ac1 a modified gene from the soil bacterium Bacillus thuringiensis (Bt). For biosafety assessment, we studied the effects on survival of cantor Daphnia magna, a commonly used as a model organism in ecotoxicological studies. D. magna fed on Bt rice and its near non-genetically modified (GM) counterparts (Nakdong) grown in the same environment (100% ground rice suspension). The Bt rice was comfirmed to have the insertion of T-DNA and protein expression by the polymerase chain reaction and ELISA analysis. Feeding study showed similar cumulative immobility and abnormal response of D. magna between Bt rice and non-GM counterparts. 48 h-EC50 values of Bt rice and non-GM rice showed 4,429 and 2,889 mg/L respectively. The rice no observed effect concentration (NOEC) values for D. magna was suggested 1,000 mg/L. We conclude that the tested Bt-rice and Nakdong similar cumulative immobility for D. magna the widely used model organism. We found out that there is strong possibility that the growth of Bt rice didn`t affect to non-target insects.

Purpose: Docetaxel (Taxotere<SUP>ⓡ</SUP>) and capecitabine are used in combination to treat advanced gastric cancer. Thymidine phosphorylase (TP) is an essential enzyme for the activation of capecitabine in tumors. This study sought to identify the best combination therapy with capecitabine and using two different schedules for docetaxel, a TP up-regulator, to enhance capecitabine’s efficacy. Methods: The human gastric cancer cell line SNU-484 was cultured and docetaxel (2㎍/㎖) was added to the 24-well plates that contained 5×105 cells/well. The total RNA was isolated and RT-PCR was done to identify the TP expression. Four- or five-week-old BALB/c-nu/nu mice were subcutaneously inoculated with the SNU-484 cells. The nude mice were divided into two groups and they were given capecitabine 539 ㎎/㎡ p.o. from days 1 to 14: Group 1 was given docetaxel 15 ㎎/㎡ i.v. on day 1; Group 2 was given docetaxel 7.5㎎/㎡ on days 1 and 8. Tumor tissues were excised on days 1, 8 and 15 to measure the TP and bcl-2 levels. Results: TP was expressed 2 hours after docetaxel administration. Group 2 had a higher TP concentration in the tumor tissues and a better antitumor effect than did Group 1. There was no difference in the bcl-2 concentration in the two groups. Conclusion: These results suggest that docetaxel stimulates the TP expression in tumor tissues and it enhances the antitumor activity of capecitabine. A weekly docetaxel injection with capecitabine administration can be used to treat gastric cancer more effectively than when docetaxel is injected once per cycle. Capecitabine had no bcl-2 suppressive effect in this study.

Comparative profiling of plasma proteome from breast cancer patients reveals thrombospondin-1 and BRWD3 as serological biomarkers

Suh, Eui Jin,Kabir, Mohammad Humayun,Kang, Un-Beom,Lee, Jong Won,Yu, Jonghan,Noh, Dong-Young,Lee, Cheolju Korean Society for Biochemistry and Molecular Bion 2012 Experimental and molecular medicine Vol.44 No.1

Breast cancer is the most common cancer in women worldwide. It is necessary to identify biomarkers for early detection, to make accurate prognoses, and to monitor for any recurrence of the cancer. In order to identify potential breast cancer biomarkers, we analyzed the plasma samples of women diagnosed with breast cancer and age-matched normal healthy women by mTRAQ-based stable isotope-labeling mass spectrometry. We identified and quantified 204 proteins including thrombospondin-1 (THBS1) and bromodomain and WD repeat-containing protein 3 (BRWD3) which were increased by more than 5-fold in breast cancer plasma. The plasma levels of the two proteins were evaluated by Western blot assay to confirm for their diagnostic value as serum markers. A 1.8-fold increase in BRWD3 was observed while comparing the plasma levels of breast cancer patients (n = 54) with age-matched normal healthy controls (n = 30), and the area under the receiver operating characteristic curve (AUC) was 0.917. THBS1 was detected in pooled breast cancer plasma at the ratio similar to mTRAQ ratio (>5-fold). The AUC value for THBS1 was 0.875. The increase of THBS1 was more prominent in estrogen receptor negative and progesterone receptor negative patients than receptor-positive patients. Our results are evidence of the diagnostic value of THBS1 in detecting breast cancer. Based on our findings, we suggest a proteomic method for protein identification and quantification lead to effective biomarker discovery.

CALCULATION OF THE STRUCTURAL STIFFNESS OF RUN-FLAT AND REGULAR TIRES BY CONSIDERING STRAIN ENERGY

Jong-Jin Bae,Youngbin You,Jong Beom Suh,Namcheol Kang 한국자동차공학회 2019 International journal of automotive technology Vol.20 No.5

The vertical stiffness of a tire is defined by the ratio of the vertical force to the deflection; it can be expressed as the combination of the structural stiffness and air stiffness. However, the calculation of the structural stiffness alone is challengeable, and therefore this paper presents a new methodology for extracting the structural stiffness from the strain energy of the regular and run-flat tires. In order to verify our proposed method, the applied force-deflection relationship was compared with the calculated force-deflection relationship using the proposed energy method at zero air pressure. Further, the structural stiffness of the inflated regular and run-flat tires was calculated. In addition, we obtained the structural stiffness of the tire components to investigate the effect of each component on the overall structural stiffness of both tires. Finally, we analyzed the vertical and structural stiffness of the run-flat tire when the inflation pressure and the elastic modulus of the components were varied.

1960년대 이후 파킨슨병의 유발물질 중 한 후보로서 망간이 주목받으면서 많은 역학적, 병러학적 연구가 수행죄브다. 그러나 망간이 파킨슨병을 직접 일으키는지, 혹은 파킨슨병과 관련된 부위의 신경세포를 파괴시쿡 파킨슨증만을 초래하는 것인지가 아직 정립되지 않은 실정이다 본 연구에서는 실험동물모델에서 행등학적 변화 측정 및 병리학적, 샐화학적 연구를 통하여 망간의 과다노출글 따른 파킨슨병 유발 여부를 확인하고자 하였다. Sprague-Datylet· 렛드에 망간을 1, 2, 5, 10 mgAg/day의 응량으로 30일 등안 복강 투여하였을 때 모든 망간투여군에서 운동성 감소가 관찰되었다. 뇌조직의 망간 함량을 ion chromatograph?로 측정한 결과 중뇌 흑질과 기저핵 선조체에서 망간 함량의 뚜렷한 증가 소견이 관찰되었으며, 니슬염색체서 선조체의 신경세포수의 유의성 있는 감소가 관찰되었다. 그러나, 흑질의 TH효소 면역염색, GFAP 면역염색, 흑질과 선조체의 T릿효소 western blot 결과는 대조군과 차이가 없었다. 이상의 결과에서, 망간-파킨슨증 모델에서 파킨슨증어 유발되는 기전은 흑질 도파민성 신경 세포의 신호를 받는 선조체 씬경세포의 사멸에 의한 것으로 생각된다. 결론적으로, 망간 독성에 의한 파킨스증 모델에서는 파킨슨 병과는 달리 흑질 도파민성 신경세포의 세포사는 관여하지 않는 것으로 관찰되었다. Manganese(Mn) intoxication causes a parkinsonian syndrome. It may be difficult to distinguish Mn-induced parkinsonism from idiopathic Parkinson disease(IPD). Neuropathological descriptions on the brains with Mn intoxication showed the perferential damage in the globus pallidus and substantia nigra pars reticularis. Pathological reports on the substantia nigra pars compacta(SNpc), a mafor focus of pathologic changes in IPD, are discordant and controversial. The SNpc involvement is of critical importance for the elucidation of pathogenesis of IPD. Therefore, the neurodegeneration in SNpc was investigated in the experimental model of Mn neurotoxicity. Sprague-Dawley rats were administered with manganese chloride(1, 2, 5, 10 mg/kg/day, i.p.) for 30 days. Treated animals showed low levels of distance-traveled from locomotor activity tests. Ion chromatography revealed that Mn accumulation was significant in SN and basal ganglia in Mn-treated animals. Nissl staining showed neuronal loss of the striatum in all treated animals. The degree of neurodegeneration in SN was determined by immunohistochemical staining of tyrosine hydroxylase(TH). The numbers of TH-positive cells on nigral sections were not different from each groups(P>0.05). The densities of glial fibrillary acidic protein immunoreactivity from SN were similar between groups. TH-westen blotting showed no differences between treated animals and controls. In conclusion, the SNpc remains intact in Mn intoxication, and Mn-induced parkinsonism may be caused by damages of output pathways downstream to the nigrostriatal dopminergic system.
