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.

Among 130 cholera patients treated in Seohae Hospital in 1991, 86 were cholera bacilli positive and remaining 44 were negative. All cholera bacilli 'positive' patients were confirmed bacteriologically by National Institute for Health team. Cholera related symptoms and laboratory findings were gathered by interviews and medical records surveys. Symptoms and some serological laboratory findings are compared between cholera bacilli 'positive' and 'negative' patients in 1991 cholera epidemic. Results are as follows: 1. There were no differences in symptoms distribution and in mean values of all serological laboratory tests done between two groups. These facts support that both cholera bacilli 'positive' and 'negative' patients are persons who have cholera bacilli infection. 2. The age distribution of the cholera bacilli 'negative' group tended to be much younger than that of 'positive' group. The infection source of this group is believed to be the environmental reservoir. This findings suggests that cholera bacilli 'negative' patients have the possibility of endemic characteristics. We think it is worth investigating Vibrio cholera antibody titers of people in area with frequent cholera epidemics in Korea.

The incidence of traumatic brain injury (TBI) has increased with the advanced technology of society. A careful evaluation of associated problems, initial severity, and complications is important for the acute management and rehabilitation of patients with TBI. To predict the rehabilitation potentials of patients with TBI, we have retrospectively investigated the causes, types of injury, associated problems, and complications in 186 patients and also assessed the rehabilitation outcomes by measuring the functional gains according to the types of brain injury and the initial severities evaluated by the Glasgow coma scale in 82 patients. The functional gains were measured by differences of the Mini-mental status examination, PULSES profile, and Barthel index of pre- and post-rehabilitation states. The incidence of TBI was highest in the 3rd decade men and the most common cause was a traffic accident (120 cases, 64.5%). The types of brain injury were a diffuse axonal injury, 87 cases (46.8%); epidural hematoma, 21 cases (11.3 %); subarachnoid hemorrhage, 25 cases (13.4%); subdural hematoma, 28 cases (15.1%); and intracerebral hematoma, 25 cases (12.9%). Common associated problems were fractures and injuries of nervous system. The 7th cranial nerve and the peroneal nerve were the most common injuries for cranial and peripheral nerves, respectively. Common complications were pulmonary and skin disorders. Total hospital stay and the duration for rehabilitation were not significantly different by the types of injury. Functional gain tended to be higher in the intracerebral hematoma compared to the other types of brain injury. The functional gain was statistically higher in patients with initial severity of moderate degree according to the Glasgow coma scale. In conclusion the moderate traumatic brain injured patients seem to have a higher potential for the good functional outcome.

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.
