Both clinical and experimental evidence suggest that immunological mechanisms are involved in the pathogenesis of endogenous uveitis. We have analyzed the percentages of T cell, B cell, T cell subpopulations(OKT4, OKT8) and OKT4/OKT8 a in seventeen patients diagnosed clinically as uveitis. The results were as follows; 1. The percentages of T cell and B cell in peripheral blood were 53.0% and 21.1% respectively. 2. The percentages of OKT4 and OKT8 and OKT4/OKT8 were 49.4%, 29.0% and 2.0 respectively, and those were in normal ranges.

The quality correction in the air kerma dosimetry for Ir-192 using farmer type ionization chambers calibrated by Co-60 quality is required. In this study we determined quality factor (kappa u) of two ionization chambers of PTW-N30001 and N23333 for Ir-192 source using dosimetric method. The quality factors for energy spectrum of microSelectron were determined as kappa u=1.016 and 1.017 for PTW-N30001 and N23333 ionization chambers respectively. We applied quality factors in air kerma dosimetry for microSelectron source and compared with reference values. As a results we found that the differences between reference air kerma rate and measured it with and without quality correction were about -0.5% and -2.0% respectively.

We report a case of acute transient encephalopathy with mental alteration, myoclonic jerks, and periodic triphasic wave electroencephalographic patterns caused by a therapeutic dose of baclofen. The clinical and electroencephalo-graphic abnormalities improved to a normal range shortly after baclofen was discontinued. We discuss the pathogenesis and review the literature about baclofen-induced encephalopathies.

PURPOSE: The purpose of this study was to develop PC-based perfusion software using Microsoft Windows. This software was developed to reformat perfusion maps including CBV (Cerebral Blood Volume), MTT (Mean Transit Time), and CBF (Cerebral Blood Flow) maps and to analyze perfusion quantitatively. MATERIALS AND METHODS: Windows-based perfusion software was developed using IDL (Interactive Data Language) as the development tool. The perfusion software was written to load the source image from dynamic first-pass cerebral perfusion CT and to reformat perfusion maps. Mean perfusion values in gray matter and white matter were calculated and compared to previously calculated data reported in literature. RESULTS: This software reformatted first pass perfusion maps in a user-friendly PC and calculated CBV, MTT, and CBF values. The values were within the normal range of the mean values when compared to previous studies. CONCLUSION: CT perfusion maps and perfusion values can be obtained by using the newly developed PC-based perfusion software. Further study is needed to achieve more precise values. However, we believe that in the future, this program may be used in various clinical settings.

PURPOSE: This study was to evaluate the accuracy of how to use the Mechanical Torque-Limiting Devices. MATERIALS AND METHODS: Three different implant manufacturers (Dentium, Osstem, Shinhung) were prepared for each two implant torque controllers. Divided into two groups depending on the method used for removal torque was measured. Repeated measures of ANOVA test (alpha=.05) was used as statistics to evaluate the effect of repeated loading number on the removal torque. Independent t-test was used to evaluate the difference in removal torque of two groups. RESULTS: The removal torque significantly decreased as the number of loading repetition increased (P<.05). There was significant difference between two groups. CONCLUSION: Loosen the handle part of the implant torque controllers spring resilience to recover one group compared to the group that did not, showed a little more closed to the reference value.
