Objective : It has been suggested that elevated cardiac troponin T (cTnT) level is a marker of increased risk of mortality in acute ischemic stroke and subarachnoid hemorrhage (SAH). However, the association of serum cTnT level and prognosis of intracerebral hemorrhage (ICH) has been sparsely investigated. The aim of this study was to identify the relationship between cTnT level and the outcome in patients with spontaneous ICH. Methods : We retrospectively investigated 253 patients identified by a database search from records of patients admitted in our department for ICH between January 1, 2003 and December 31, 2007. The patients were divided into 2 groups; the patients in group 1 (n=225) with serum cTnT values of 0.01 ng/mL or less, and those in group 2 (n=28) with serum cTnT values greater than 0.01 ng/mL. Results : The serum cTnT level was elevated in 28 patients. There were significant differences in sex, hypertension, creatine kinase-myocardial band, midline shift, side of hematoma, and presence of intraventricular hemorrhage between the 2 groups. Logistic regression analysis identified the level of consciousness on admission, cTnT and midline shift as independent predictors of hospital mortality. Conclusion : Theses results suggest that increased serum cTnT level at admission is associated with in-hospital mortality and the addition of a serum cTnT assay to routine admission testing should be considered in patients with ICH.

We synthesised a photo-alignment material of PM4Ch (poly(4-methacryloylloxychalcone)). The electro-optical (EO) characteristics of photo-aligned twisted nematic (TN)-liquid crystal display (LCD) with linearly polarized ultraviolet (UV) light irradiation on PM4Ch surface were investigated. The uniform alignment of NLC with polarized UV light irradiation on PM4Ch surface was measured. Also, We had The excellent voltage-transmittance characteristics of photo-aligned TN-LCD. The low threshold voltage of photo-aligned TN-LCD was measured. Moreover, the fast response time of photo-aligned TN-LCD on PM4Ch was successfully achieved. Finally The reduction DC voltage of photo-aligned TN-LCD decreases with increasing the UV light irradiation time on photo-dimerized PM4Ch surface.

In this paper, we have studied on the optimal design of the optical compensation film for the TN-LCDs. To have wide viewing angle panels, several methods such as multi-domain method, optical path method, and phase compensation method have been proposed. Among these methods, this paper focused on the phase compensation method. In the phase compensation method, the phase retardation generated from the optical birefringence for the off-axis incident is compensated by using optical films with refractive anisotropy. To compensate the phase retardation of the TN-LCDs, we have proposed design concept for the biaxial optical films and analyzed the optical performance for the proposed structures. The calculation of the dynamic motion of the liquid crystals was based on the Ericksen-Leslie theory and the optical performance of the TN-LCD was calculated from the Extended Jones Matrix Method. From the results, we have confirmed that the optical characteristics of the TN-LCDs with the biaxial films have been improved considerably compared with the TN-LCDs compensated by the combination of the uniaxial films.

We produced twelve monoclonal antibodies(mAbs) against thyroglobulin and characterized the bindig profiles. Among them, three mAbs(TN-1, TN-2 and TN-3) were further characterized their binding specificities. TN-2 had a potent lupus anticoagulant activity and potentiated the anticoagulant effect of venom phospholipase A₂. he anticoagulant mechanism of TN-2 was elongation of the partial thromboplastin time and binding to phosphatidylserine which may have a pivot role in blood coagulation. And TN-2 was cross-reacted with ss-DNA and ds-DNA and had a characteristic of autoantibody. These results suggest that TN-2 may provide a useful tool for studying the correlation between autoimmune thyroiditis and its therapeutic effect.

We investigated the EO performances of the UV aligned twisted nematic liquid crystal display (TN-LCD) with the UV exposure on a-C:H thin film surface. LC alignment using UV exposure on the a-C:H thin film surface was achieved. Monodomain alignment of the UV aligned TN-LCD can be observed. An good EO characteristics of the UV aligned TN-LCD was observed with oblique ion beam exposure on the a-C:H thin film surface. Therefore, the EO property of the UV-aligned TN-LCD with UV exposure on the a-C:H thin film surface is almost the same as that of the rubbing-aligned TN-LCD on a polyimide (PI) surface.

Two gentamicin resistance R plasmids, pGM5 and pGM6, containing aacC2 gene were selected from environmental isolates. The gentamicin resistance determinants of R plasmids were cloned into the BamHI site of pUC18. Restriction enzyme map of inserted region of recombinant plasmids, pSYS and pSY6, and PCR results indicated that Tn3 sequence was located upstream of gentamicin resistance gene. Based on the restriction maps and susceptibility tests, it was concluded that the sequence of bla and 3' inverted repeat of Tn3 play a important roles in the expression of gentamicin resistance gene.

Plasmid DNA molecules containing strong promoter upstream from IS50L or IS50R, the two insertion sequences that flank Tn5, were constructed to amplify the synthesis of Tn5-encoded polypeptides. When proteins made by cells that contain these plasmids were analyzed on polyacrylamide gels, enhanced synthesis of IS50R polypeptides could be detected. Synthesis of this polypeptide apparently is initiated within the large open reading frame of this element. In addition, the stability of IS50L-and IS50R-encoded polypeptides was analyzed. It was found that IS50L polypeptides are relatively unstable in vivo. This instability could account for the observed inability of this element to promote transposition.

Trigeminal neuralgia (TN) is characterized by recurrent paroxysms of unilateral facial pain that typically is severe, lancinating, and activated with cutaneous stimulation. There are two types of TN, classical TN and atypical TN. The pain nature of classical TN are the same as those described above, whereas atypical TN is characterized by constant, burning pain. We describe the case of a 49-year-old male presenting with right-sided facial pain. The patient was diagnosed with temporomandibular joint disorder at a dental clinic and was on medical treatment, but his symptoms worsened gradually. He was referred to our pain clinic for further evaluation. Radiologic evaluation, including MRI, showed a parapharyngeal tumor. For the relief of TN, a right mandibular nerve (V3) root block was performed at our pain clinic, and then he was scheduled for radiation and chemotherapy.
