Cd_1-xMn_xTe single crystals were grown by vertical Bridgman method and Mn mole fraction x was determined by the X-ray diffraction. Band gap and optical transition energies E₁, E₁+ △₁, E₂, △₁as Mn mole fraction x were obtained by measuring optical absorption and reflection at UV-visible region respectively. The change of the valence band spin-orbit splitting △₁at △ point of the Brillouin zone was discussed.

This study was conducted for the purpose of suggestion of the new technique of sagittal split ramus osteotomy pararell to the true sagittal plane. This pararellism is the important concept of the sagittal split ramus osteotomy to reduce the condylar sagging including mandibular hypomobility, tempormandibular disorder, occlusal relapse and other complications. We used 26 adult dry manibles(52 rami), and obtained the computed tomographs through the sagittal, horizontal and coronal sections. The results were obtained as follows. 1. On sagittal section, mean area of S1 was 8.63±2.10㎠, S2 was 8.93±1.94㎠, S3 was 9.49±2.15㎠, S6 was 10.72±2.22㎠. The wider area of sagittal section, the more lateral section, But, no singnificant differency between the areas of the sagittal sections(P>0.05). 2. On horizontal section, The distance between the inferior alveolar canal and the lateral cortical plate of the mandibular ramus were 6.73±1.24mm minum, 7.70±1.44mm maximum. 3. On coronal section, Outer mandibular angle were 4.84±2.37˚right side, 4.93±2.12˚left side. 4. The design of the ideal true sagittal split ramus osteotomy is that posterior border of osteotomy must be limited vertically, at the right posterior point of lingula mandibularis and anterior of osteotomy must be extended to mandibular body, anteroinferiorly.

Primary biliary cirrhosis is a chronic, progressive liver disease characterized by inflammatory destruction of septal and intralobular bile ducts which results in intrahepatic cholestasis. Although the cause remains obscure, it is frequently associated with a variety of disorders presumed to be autoimmune in nature. We report a case of early primary biliary cirrhosis which was anteceded by rheumatoid arthritis. The patient was a 54-year-old female who was admitted due to arthralgia and joint deformity. She had been diagnosed as having rheumatoid arthritis 10 years before. On admission, she had elevated serum ALT, AST, alkaline phosphatase, gamma-GTP and positive serum antimitochondrial antibody test. Microscopic findings of the liver were consistent with the early stage of primary biliary cirrhosis.

Background and Objective: Mechanical laundry has a key role for environmental control of allergens. However, the optimal conditions for removing allergens such as house dust mite (HDM), dog dander, and pollens are not yet clear. Method: Four cleaning modes such as 30℃, 40℃, 60℃, and steam (adapt steam and water cleaning) were evaluated. Viability of HDM was assayed with heat escape method and levels of group 1 major allergens of D. farinae (Der f 1) and dog dander (Can f 1) were assayed with 2-site ELISA. Levels of pollen protein were assayed with Bradford method. Result: At 60℃ and steam cleaning modes, all HDM were dead but at 30∼40℃ modes, only 6.4∼9.3% of HDM were dead. The levels of Der f 1 in extraction buffers immediately after 30℃, 40℃, 60℃, and steam cleaning were 26.8%, 2.4%, 1.3%, and 0.6%, respectively. The levels of Can f 1 were 41.5%, 42.7%, 12.6%, 9.8% and the pollen protein levels were 31.8%, 4.9%, 3.9%, and 2.8%, respectively. Conclusion: Steam and 60℃ cleaning is better than 30∼40℃ cleaning for removing indoor and pollen allergens. (Korean J Asthma Allergy Clin Immunol 2006;26:289-296)

Objective: To compare the use of 3D driven equilibrium (DRIVE) imaging with 3D balanced fast field echo (bFFE) imaging in the assessment of the anatomic structures of the internal auditory canal (IAC) and inner ear at 3 Tesla (T). Materials and Methods: Thirty ears of 15 subjects (7 men and 8 women; age range, 22 71 years; average age, 50 years) without evidence of ear problems were examined on a whole-body 3T MR scanner with both 3D DRIVE and 3D bFFE sequences by using an 8-channel sensitivity encoding (SENSE) head coil. Two neuroradiologists reviewed both MR images with particular attention to the visibility of the anatomic structures, including four branches of the cranial nerves within the IAC, anatomic structures of the cochlea, vestibule, and three semicircular canals. Results: Although both techniques provided images of relatively good quality, the 3D DRIVE sequence was somewhat superior to the 3D bFFE sequence. The discrepancies were more prominent for the basal turn of the cochlea, vestibule, and all semicircular canals, and were thought to be attributed to the presence of greater magnetic susceptibility artifacts inherent to gradient-echo techniques such as bFFE. Conclusion: Because of higher image quality and less susceptibility artifacts, we highly recommend the employment of 3D DRIVE imaging as the MR imaging choice for the IAC and inner ear.
