We intended to evaluate the Young's modulus of trabecular bone and apparent density from Computed Tomography(CT) and Spherical Indentation test and to quantify relation ship between them. The distal femurs(31 age, male, left and right) were prepared for exprimentatin and were embedded with repect to anatomical orientation. Then the specimens were scnned at 1 mm intervals on GE9800 CT scanner and the Hounsfield Units(HU, or CT number) were extracted from each CT image. After scanning, the bones were sectioned with diamond saw, producing 8 mm cubes of trabecular bone(72 eachs) from the metaphyseal region of both distal femur. The cubes were mechanically tested in inferior-superior(IS), anteriorposterior(AP), and medial-lateral(ML) direction with custom-made device, Spherical Indentatin Tester. After testing, the real apparent density of specimens were measured. The results of this study showed that the IS modulus was singificantly greater than both the AP and ML modulus and the AP modulus was also greater than ML modulus significantly(p<0.01). A linear relation ship between HU and real apparent density was found to be significant(R2=0.68) and significant power relationship between the apparent density and the tangent moduli(either by CT or physical measures) was also found.

Astrocytes are the most numerous cellular elements in the cerebrum, and they normally have a very slow turnover rate. But during regeneration after injury, they proliferate markedly resulting in astrogliosis. The extracellular matrix in the central nervous system is present in the vessel walls and in the external glia limitans as a basal lamina. The presence of an intact extracellular matrix framework is important in regeneration after injury. Understanding the properties of astrocytic proliferation will be helpful to find out new treatment for functional recovery in the central nervous system. In this study, after cryogenic injury was performed on the cerebral cortex in rats, changes in astrocytes and the extracellular matrix were observed using light microscopy, immunohistochemical stain for glial fibrillary acidic protein(GFAP), proliferating cell nuclear antigen(PCNA), fibronectin, laminin, and type IV collagen, autoradiography and electron microscopy. The results were as follows; 1) The coagulative necrosis, which followed cryogenic injury on the cerebral cortex was healed, forming a new pia mater above the lesion. 2) Some of the PCNA positive cells were astrocytes and some of the GFAP positive cells showed a positive reaction to PCNA. 3) Proliferating astrocytes labelled by autoradiography or immunohistochemical stain for PCNA reached maximal numbers 3days after the injury and they were no longer found 2 weeks after injury. 4) In autoradiography with immunohistochemical stain for GFAP, about 1% of GFAP positive astrocytes were labelled by autoradiography and in double immunohistochemical stain for PCNA and GFAP, about 8-16% of GFAP positive astrocytes were also stained by PCNA. 5) In immunohistochemical stain for fibronectin, laminin and type IV collagen, laminin and type IV collagen were present in the newly formed blood vessel walls and fibronectin showed a diffuse positive reaction within the lesion. The new pia mater was formed within 2 weeks after the injury. 6) On electron microscopic examination, basal lamina material was found in the vessel wall 1 week after the injury and at 2 weeks, a nearly complete and continuous basal lamina was formed although the thickness was uneven. According to these findings, astrocytes in the cerebral cortex of adult rats proliferate very early in the regenerative period after cryogenic injury. At 2 weeks after the injury, this regeneration ceases and the damaged basal lamina of pia mater and vessel wall were reconstituted.

BACKGROUND: thermotherapy has been shown to be effective in the treatment of some fungal infections. Dermatophyte are well grown at 25degrees C rather than 37degrees C or high temperature. OBJECTIVE: An vitro test was done to assess the complemental effect and optimal conditions of local heating on the susceptability of t. rubrum to systemic antifungal agents. METHODS: Microdilution susceptability test to ketoconazole and itraconazole was done using 96 well microplate. Eight strains of T. rubrum were isolated from patients withtinea pedis and were cultured at 25degrees C, 37degrees C and 42degrees C for 1, 8 or 24 hours per day. MIC were checked at 4th, 7th, 9th day after inoculution. RESULTS: The growth without antifungal agents at 37degrees C and 42degrees C were decreased by 805 and 50% of the growth at 25degrees C respectively. Seven day after inoculation was the proper time to check the MIC. MIC50 of ketoconazole was the lowest at 42degrees C for 24hours per day in value of 0.006microgram/ml, and 0.09microgram/ml at 37degrees C for 24hours per day, 0.37microgram/mlat 42degrees C, for 8hours per day and 37degrees C for 8hours per day. MIC at 42degrees C for 1 hours er day, 37degrees C for 1 hyours and 25degrees C for 24hours per ady MIC were the same in value of 0.05microgram/ml. MIC50 of itraconazole was the lowest at 42degrees C for 24hours per day in value of 0.006microgram/ml, 0.01microgram/ml at 37degrees C for 24hours per day, 0.02microgram/ml at 37degrees C for 8hours per day. MIC at 42degrees C for 8hours per day, 42degrees C for 1hours per day, 37degrees C for 24hours per day MIC were the same in value of 0.05microgram/ml. CONCLUSION: Incubation at 37degrees C for 24 hours per day or 42degrees C for 24 hours per day increased the susceptability of T. rubrum to ketoconazole and itraconazole.

To evaluate usefulness of MR in assessment of tumor response to the chemotheraphy, we prospectively studied cases of cervical carcinoma with more then 2.5cm in diameter or stage IIb or more. Three courses of chemotherapy were performed with cisplatin and 5 F-U. MR images were obtained both before and after chemotherapy. Nine of 13 patients were undertaken radical hysterectomy after chemotherapy and MR examination. MR volumetry, stage and depth of stromal invasion were compared before and after chemotherapy. And in 9 patients who underwent radical hysterectomy, comparison of pathologic and MR imaging findings were also done. @ES The results were following. @EN 1) All tumors dectrased in volume (m=80.5%). 2) Five tumors (38.5%) reduced in stage, IB→CIS(1); IIA→CIS(1), IIA→IB(2), IIB→IB(1). 3) Depth of stromal invasion in MRI correlated well with that of histo-pathologic specimen in 7 of the 9 patients. Conclusively MR imaging is useful in assessement of tumor response to chemotherapy.

We report a case of type IV hyperlipoproteinemia associated with xanthoma tuberosum and diabets mellitus in a 48 year old female patient. She had several yellowish-brown papules on the knees and palms. The blood glucose level was elevated and serum lipid and lipoprotein analysis revealed patterns of type IV hyperlipoproteinemia. Histopathologic findings of yellowish-brown papules on the knee showed the aggregation of foam cells in the dermis. She has been treated with diet control and hypolipidemic drug(lovastatin and procetofen) and is under our continuing supervision.

PURPOSE: The purpose of this study is to evaluate the effectiveness on decrease of the exposure rate of Medpor(R) implant (high-density porous polyethylene) when the suture material is left permanently without removal after continuous vertical suture of conjunctiva and Tenon's capsule with non-absorbable material, polypropylene suture (Prolene(R)). METHODS: We performed 66 cases of Medpor(R) orbital implantation in conjunction with enucleation, evisceration, or secondary orbital implantation between November 1997 and February 2002, and reviewed the charts of patients retrospectively. We divided 66 cases into 2 groups; One is Polypropylene group (P group, 30 eyes), in which conjunctiva and Tenon's capsules were sutured with double shoe string technique by 5-0 polypropylene sutures in one layer, and the other is control group (36 eyes), in which conjunctiva and Tenon's capsules were sutured by 5-0 polyglactin (Vicryl(R)) in separate layer, or Tenon's capsules were sutured by 5-0 Vicryl(R) and conjunctivae were 7-0 silk. We compared P group with control group with regard to the exposure rates, irritations, conjunctivitis and assessed covering of polypropylene suture by conjunctival epithelization. RESULTS: In control group, 5 of 36 eyes (13.8%) had the exposures of Medpor(R) implants, 21 eyes (58.3%) had the irritations, and 10 eyes had conjunctivitis. But, there was no exposure of Medpor(R) implants in all cases of P group, only two of 30 eyes had the irritations, and 3 eyes had conjunctivitis. There were significant differences between the two groups in the rates of exposure and irritations, but in the eyes with conjunctivitis, there was no significant difference between the two groups (Table 5, chi-square test). After 2 months of operation, the wound surfaces were smooth with complete covering of polypropylene suture by appropriate conjunctival epithelization. CONCLUSIONS: Continuous vertical suturing of conjunctiva and Tenon's capsule with non-absorbable polypropylene suture (Double shoestring technique) substantially reduced the exposure of Medpor(R) implant in addition to less inflammations, irritations and more comfortability. We concluded that the suture materials and methods must be considered as the important causes of exposure in enucleation or evisceration using proper Medpor(R) implant.
