The goals of this paper are not only to reduce of noise using anisotropic diffusion filter post-processing but also to represent 3-D image using 2-D image slices by volume rendering. A 3D shape image can be obtained as the 2-D images are continuously acquired, during the object is removed noise by filtering. The 3-D shape images are displayed on computer monitor by use of OpenGL Software.

Objectives:Hemiplegic patients with unilateral cerebral lesions suffer from sensory deficit as well as motor deficit. But clinical assessment of thermal sensation is one of the least reliable components of neurological examination and is difficult to quantify. Methods:We measured thermal sensory thresholds of cold sense, warm sense, cold pain and hot pain in hemiplegic patients with thermal sensory analyzer(TSA). To investigate and quantify the thermal sensory deficit of hemiplegic patients, we compared the measurements with normal con-trols, between body regions, and between hemiplegic and sound side. Results:Hemiplegic patients showed impaired thermal sensory thresholds in all modalities compared to their sound side and normal controls. Conclusion:Quantitative sensory test using thermal sensory analyzer can be useful to quantify the thermal sensory deficit and follow up the progress.

Acute A viral hepatitis is a mild, self-limiting disease of liver and acute renal failure (ARF) is a rare complication. We report two cases of chronic renal failure (CRF) in nonfulminant acute A viral hepatitis and ARF. A 40-year-old man was admitted with ARF and acute A viral hepatitis, and underwent temporary hemodialysis therapy. The renal biopsy showed acute tubular necrosis with tubulointerstitial nephritis. At 13 months after discharge serum creatinine was 1.33 mg/dL and protein-creatinine ratio of spot urine was 0.47 (mg/mg Cr). The second case was a 28-year-old man and was managed conservatively. At discharge the serum creatinine was 3.14 mg/dL and the urinalysis showed hematuria, and protein-creatinine ratio 0.56 (mg/mg Cr). Thirty-nine months after discharge, the creatinine was 1.23 mg/dL, the urinalysis showed persistent nephritis findings and the protein-creatinine ratio 1.28. Kidney biopsy revealed the membranous glomerulopathy with mild tubulointerstitial nephritis, and all of findings suggested the systemic disease-associated secondary glomerulopathy. To our knowledge our case is the first one of chronic glomerulapathy that is confirmed by kidney biopsy.
