Necleolar organizer regions(NORs) ARE LOOPS OF DNA which transcribe to ribosomal RNA by RNA polymerase I. Since NOR-associated proteins are argyrophilic, silver staining method has been used for demonstration of AgNORs. The numbers and/or configurations of NORs may reflect the activities of cells in hyperplastic and neoplastic conditions. To evaluated the applicability of AgNORs in the diagnosis of hepatocellular carcinoma, the author had performed silver staining on the routinely processed, formalin-fixed, paraffin-embedded sections of 14 cases of normal liver(control), 23 cirrhotic liver, and 21 hepatocellular carcinoma. The results are summarized as follows: 1) The mean number of AgNORs per nucleus(mAgNOR) of normal liver, cirrhotic liver and hepatocellular carcinoma was 1.45+/-0.07, 2.53+/-0.38 and 5.52+/-1.63, respectively. The difference of mAgNOR between normal and cirrhotic liver, and between cirrhotic liver and hepatocellular carcinoma was statistically significant, respectively(p<0.01). 2) The percentage of nuclei showing five or more AgNORs per nucleus(pAgNOR) was 0.07% in normal liver, 7.59% in cirrhotic liver, and 60.49% in hepatocellular carcinoma. 3) AgNORs in hepatocellular carcinoma were large, pleomorphic and irregularly clumped, in addition to increase of mAgNOR and high pAgNOR. In conclusion, the increase of mAgNOR, high pAgNOR and large, irregular AgNORs are regarded as an additional helpful finding for the histopathological diagnosis of hepatocellular carcinoma.

OBJECTIVE: This study aimed to develop a web-based exercise program based on a preliminary survey and to evaluate its effect for promotion of exercise among chronic patients. METHODS: For the preliminary survey, an investigation of internet use among chronic patients and a review of existing 20 exercise-related web-sites were undertaken. The web-site was developed and evaluated by user satisfaction with the site and expert validity. To evaluate the effect of the site, exercise stage and commitment to a plan for exercise were compared before and after using the site. RESULTS: The content of the web-site included exercise and health, exercise prescription, chronic disease and exercise, and my page. The users rated 3.89 for system, 3.81 for content, and 3.60 for design in the satisfaction with the site. Experts rated 4.62 for feedback and privacy, 4.31 for purpose, 4.23 for authorship, 3.76 for content, 3.71 for design, 3.62 for functionality in the evaluation of the site. The commitment to a plan for exercise after using the site was significantly higher than that before using it. CONCLUSION: This site can be facilitated to enhance physical activity for chronic patients and further effort to continuously use and revise the site is recommended.

OBJECTIVE: To compare the effects of intermittent mechanical traction with spinal decompression therapy (SDT), using the newly introduced device DRX 3000(R), in patients suffering from low back pain associated with lumbosacral disc herniation documented on MRI. METHOD: Thirty-five patients with low back pain with or without lower extremity radiating pain were prospectively enrolled in this study. They were all diagnosed with lumbosacral disc herniation according to physical examinations and MRI. Patients over age 60 years or those with previous spinal surgery, spondylolisthesis, severe osteoporosis, rheumatic diseases, hypertension, and other serious medical problems were excluded. Patients were randomly assigned to intermittent mechanical traction group (15 patients) or SDT group (20 patients) and compared visual analog pain scale (VAS) pre- and post-treatment. RESULTS: There was a significant improvement in VAS in SDT group compared to intermittent mechanical traction group. The mean reduction in VAS for intermittent mechanical traction group equaled 1.93+/-0.83 (from 6.4+/-1.28 to 4.5+/-1.22) while the mean reduction in VAS in SDT group equaled 4.35+/-2.21 (from 6.9+/-1.86 to 2.6+/-1.43) (p=0.0006). CONCLUSION: Spinal decompression therapy can be used as an effective treatment for discogenic low back pain without serious complications.

Lichen aureus is a variant of pigmented purpuric lichenoid dermatitis. The skin lesions usually appear asymptomatic rusty, copper, or orange colored roundish lichenoid erythematous-purpuric papules and patches on the lower extremities. Histologically, the epidermis shows minimal changes, with a dense lymphohistiocytic infiltrate observed in the superficial derrnis, typically distributed in a band-like fashion. The typical lesion is a single patch localized on the lower extremity. We report a rare case of segmental lichen aureus localized on the right lower extremity.

Calcareous corpuscles are a characteristic structure found in larval and adult stage cestodes. These corpuscles are known to contain several protein components and to possess protein-binding activity. However, the proteins bound to calcareous corpuscles in situ have not been studied. The present study was undertaken to identify the proteins on calcareous corpuscles. Calcareous corpuscles were purified from the plerocercoids (= spargana) of Spirometra erinacei, and serially dissolved using 0.1 M sulfamic acid solution. Collected supernatants were examined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and silver staining. The results showed that only the fraction remaining after the 19th dissolved fraction contained proteins. A total of 20 protein molecules were detected in gel, with major bands at 56, 53, 46, 40, 35, 29, 28, 24.5, 21, 19, 16, 13, 10 and 8 kDa. In particular, the proteins corresponding to the 21 and 16 kDa bands were most abundant. Our results demonstrated for the first time the protein contents of the calcareous corpuscles of spargana. Further studies on the functions of these proteins are required.
