BACKGROUND: To evaluate usefulness of cerebrospinal aspartate aminotransferase(AST) as a biologic marker for differentiation of Alzheimer's disease(AD) and Vascular dementia(VD) METHODS: A consecutive series of patients who met either the criteria of the National Institute of Neurological Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association(NINCDSADRDA) for probable AD or National Institute of Neurological Disorders and Stroke and the Association Internationale pour la Recherche et l'Enseignement en Neurosciences(NINDS-AIREN) criteria for porbable VD were included in the study. Enzymatic determinations in cere brospinal fluid of aspartate aminotransferase in cerebrospinal fluid of aspartate aminotransferase and serologic analysis of apolipoprotein E were performed in 17 patients with AD and in 15 patients with VD. And we compared CSF AST of AD with that of VD. RESULTS: We found no difference of CSF AST concentration between patients with Alzheimer's disease and vascular dementia. Cerebrospinal AST activity also did not correlate with K-MMSE score, serum AST activity, Functional inde-pence measure(FIM) as a ADL(Activity of daily living), and presence of Apolipoprotein E4 allele in AD. Only serum AST of VD shows correlation with CSF AST. CONCLUSION: These findings suggest that cerebrospinal AST concentration is not useful maker for differentiation between AD and VD.

Reversible posterior leukonecephalopathy syndrome RPLS), a neurologie disorder associated with evidence of posterior cerebral edema on neuroimaging studies, has been described in both adults and children. Conditions predisposing to RPLS include malignant hypertension, renal dysfunction, toxemia of pregnancy, interferon therapy, and the use of immunosuppressive agents. When associated with acute hypertension, RPLS typically occurs concurrently with the fulminant clinical syndrome of hypertensive encephalopathy We describe occipital lobe seizures, in the setting of only moderate elevations of blood pressure, as the major clinical manifestation of RPLS.

Forytfour-year-old female inpatient, who was gravely ill, developed vesicobullae on the greenish patches surrounded by narrow red to brown halo in the left lower extremity. Two years ago, she had treated by surgical operation and radiation therapy for cervix cancer. Blood and bullous fluid cultures showed Pseudomonas aeruginosa. She developed gangrenous and mummificated skin lesions after septic shock therapy but died due to disseminated intravascular coagulation.

A 18-year-old male patient presented with the skin colored, dome-shaped, soft, movable mass in his left retroauriculr region. The mass has slowly increased in size since birth. Histopathologic exarnination revealed sebaceous gland, eccrine gland and crosssectioned hair in the surrounding tissue, hair shaft projected into the lumen, and laminated horny material in the cyst. Transitional zone between stratified squarnous epithelium and the wall lined by histiocytes showed homogenous degenerative change. After surgical removal of the lesion, no recurrence was observed during 15 months of follow-up.

Of the bronchographic findings of 408 patients, performed in our hospital for recent 5 years, 108 cases showed definite bronchial obstruction, and 61 cases of those were selected and their obstructive findings were evaluated. All that not confirmed were abandoned. For evaluation of the reliability of 9 bronchographic obstruction signs onappplying to diagnose malignant or benign pulmonary diseases, each sign was identified and applied to each of the61 confirmed cases. In addition, obstructed bronchi, distance of obstruction from the bifurcation site, and thedirection of meniscus, if peresent, were evaluated. The reuslts were follows; 1. The most frequent cause ofbronchial obstruction was lung cancer (59.0%), and that of the benign obstruction was pulmonary tuberculosis(13.1%). 2. Amputation, asymmetric narrowing, thumbprint indentation, rat-tail narrowing and encasement signs werethe most accurate signs of malignancy and were practically diagnostic ones, 3, The most frequent sign in lungcancer was sharp cut off one, but it could be seen in lung abscess and in unresolved pneumonia, too. 4. Circumferential symmetric narrowing and regular concavity with a small central profection signs were specific onesto benignancy. 5. The most frequent obstruction sign in benign lung disease was gradual tapering sign, but it alsocould be seen inbronchogenic epidermoid and alveolar cell carcinoma. 6. Of all bronchial obstructions, 55.4% occurred at lobar bronchus and 77.4% of those were caused by lung cancer. 7. 77.2% of those obstruction which located within 3 times distance of the bronchial diameter at the nearest proximal bifurcation site, were lungcancer, but 75.0% of those located at over 3 times distance were benign pulmonary diseases. 8. There were nocorrelation of the direction of the meniscus at the obstructing and in differential diagnosis between benign andmalignant pulmonary diseases.

PURPOSE: To describe the appearance and average thickness of the internal anal sphincter with anal endosonography in healthy Korean adults. MATERIAL AND METHODS: 184 subjects(male: 96, female: 88) with no history of anorectal disease or surgery were studied with anal endosonography. The average thickness of internal sphincter was meas ured at the mid-anal canal. For the internal sphincter, which is often asymmetric, the thickness of each 4 part(12, 3, 6 and 9 o'clock direction) were measured in left lateral decubitus position. RESULTS: The anal wall was well visualized in 5 layers(mucosa, submucosa, internal anal sphincter, intersphincteric plane, external anal sphincter) with anal endosonography. The anal endosonogram showed the internal anal sphincter as a homogenous, well-defined, hypoechoic, circular band, and slightly asymmetric. The average thickness of the internal anal sphincter in the area of mid-anal portion was 2.0 0.3 mm(range: 1~3 mm). There was no sexual difference; however, a significant positive correlation with age was found in average thickness of the internal anal sphincter. The correlation with lean body mass was not found. CONCLUSION: The internal anal sphincter is well-visualized, best defined structure by anal endosonography. Average thickeness of the sphincter in Korean appeared to be the same as in the Western.
