STUDY DESIGN: Lumbar disc degeneration and segmental instability of the lumbar spine are causes of low back pain. Disc degeneration causes specific changes of the intervertebral disc, and could affect anatomic variations of end plate and vetebral body. However, the exact relationship between degenerative changes of the intervertebral disc and segmental motion characteristics is not known. It is known that radial tears of the annulus fibrosus initiate or accompany degenerative process of nucleus pulposus and the motion segment. It is hypothesis of this study that the existence of radial tear in the annulus fibrosis affects 3 dimension motion characteristics of motion segment. For the purpose, the degree of intervertebral disc degeneration is newly classified by existence of radial tear. Then, the resulting biomechanical motions are investigated. OBJECTIVES: To investigate effects of disc degeneration by the classification on kinematic motions of the motion segment from human lumbar spine and to suggest a quantified method to determine spinal instability in vivo. MATERIALS AND METHODS: A total of 60 spinal motion segments from human lumbar spine was used for this study. To measure 3 dimensioal motion of the motion segments, Vicon system(Oxford, England) with 3 cameras reflective markers and VAX station was used. 6 kinds of pure moments(flexion, extension, right and left axial rotation, and right and left lateral bending) were applied to the motion segments using dead weight for each loading step. At the end of test(maximum loading), motion segments were frozen for anatomical study. For making clear the degree of the degeneration of the disc, a new classification based on MRI results was used: Grade 1 is a normal young disc without tear; Grade 2 is a normal aging disc without radial tear; Grade 3 is a degenerative disc with radial tear; and Grade 4 is a severely degenerative disc with radial tear and other degeneration such as showing decreased disc height. RESULTS: The upper lumbar specimens with radial tears has increased flexion motions as compared to the normal group. Also, the right and left axial rotation in radial tear group increased as compared to the normal group. However, there were no statistical differences in other motions. For the lower lumbar specimens, there were no significant differences in measured motions in all directions between the normal and radial tear groups CONCLUSIONS: These results suggests that the segmental motions are affected by radial tear in the intervertebral disc. Thus, the radial tear in the annulus fibrosus of lumbar intervertebral disc could cause the instability of lumbar spine. Further research is required to determine the relationship between other structural changes and biomechanical characteristics, and future studies should include in vivo investigations to correlate these findings to patients'symptoms.

A 43-year-old male patient showed well defined, irregular, dark eythematous, thick plaque and tumor with ulceration on the right chest, right axilla, pubis and scrotum, Histopathological findings rervealed atypical lymphocytes showing epidermotrophism and heavy infiltrations in the deep dermis and subcutaneous tissue. The infiltrative cells were positively stained with leukocyte common antigen and T-cell UCHL-1 antigen, but not with L26 antigen. This clinicohisto-pathological features were consstent with dermblade type of mycosis fungoides. The authors report clinicopathological findings of the case with its thrapeutic responses to systemic chemotherapy and radiation treatment.

Glutathione S-transferase (28GST) with molecular mass of 28 kDa is an antioxidant enzyme abundant in Clonorchis sinensis. In adult C. sinensis, 28GST was localized in tegumental syncytium, cytons, parenchyma, and sperm tails examined by immunoelectron microscopy. C. sinensis 28GST was earlier found to neutralize bioreactive compounds and to be rich in eggs. Accordingly, it is suggested that 28GST plays important roles in phase II defense system and physiological roles in worm fecundity of C. sinensis.

After Drainage implant surgery, erosion of conjunctiva or cornea over tube can occur about 5%in late postoperative period. Scleral allograft for exposed tube should be used to prevent secondary infection. We report three glaucoma patients treated graft with autologous buccal mucosal transplantation for recurrent tube exposure. First case was a 68-year-old male patient with neovascular glaucoma due to central retinal vein occlusion. Second case was a 37-year-old female patient with pseudophakic glaucoma. Third case was a 70-year-old male patient with diabetic neovascular glaucoma. Ahmed glaucoma valve implant surgeries were done for three patients. For tube exposure, we used autologous buccal mucosal transplantation. There was no recurrent erosion and intraocular pressure was maintained well more than 6 months of follow-up. In cases for tube exposure, we introduce that autologous buccal mucosal transplantation can be used to treat tube exposure.

A poor prognosis of oral squamous cell carcinoma (SCC) is partly due to the invasiveness and metastasis of the tumor. A key element in tumor invasion and metastasis in the degradation of extracellular matrix is matrix metalloproteinases (MMPs). This study was performed to determine the expression of MMP-2 and MMP-9 of oral SCCs with regard to the histologic invasiveness and differentiation in 5 normal oral mucosa and 36 oral SCCs. The histologic invasiveness of oral SCCs were classified into 4 grades. The differentiation of oral SCCs was divided into 3 grades. The streptavidin-biotin immunohistochemical staining, using MMP-2 and MMP-9 monoclonal antibodies, was performed to determine the expression of MMP-2 and MMP-9. The expression of MMP-2 was positive in 6 of 17 oral SCCs with weak invasiveness and was positive in 7 of 19 oral SCCs with strong invasiveness. The MMP-2 expression did not increase significantly with respect to the invasiveness of oral SCCs (P>0.05). The expression of MMP-9 was strongly positive in 6 out of 17 SCCs with weak invasiveness and was strongly positive in 14 of 19 SCCs with strong invasiveness. The MMP-9 expression increased significantly with respect to the invasiveness of oral SCCs; the stronger the expression, the stronger the invasiveness (P<0.05). The expression of MMP-9 was in 57.9% of well differentiated SCCs, 57.1% of moderately differentiated ones, and 33.3% of poorly differentiated SCCs. The expression of MMP-2 and MMP-9 did not increase significantly with respect to the histologic differentiation. We conclude that with respect to the invasiveness, the MMP-9 expression increases significantly in oral SCCs but the MMP-2 expression does not; and that with respect to the histologic differentiation, their expressions do not increase significantly. These results suggeste that MMP-9 can be used as a tool to evaluate the invasiveness of oral SCCs.
