A fracture of the femoral neck in a young adult differs from the same fracture in an older patient in the following respects; 1. A relatively uncommon injury. 2. A significant difference in the severity of trauma. 3. A less satisfactory result. At the point of view, we studied the femoral neck fcartures in 15, 20- to 50-year-old patients. The aims were to analyze why these fractures occur in young adults, and what results can be expected after internal fixation. The results were as follows; 1. Common in men (3:1). 2. 80% (12/15 cases) of the fractures were caused by severe trauma. 3. The 3 cases (20%) were associated with the other fractures. 4. The factors infuencing the clinical results and complications in our study; a. Severity of trauma. b. Degree of displacement. c. Existence of posterior comminution. d. Time interval between accident and operation. 5. The multiple pinning got the more rigid fixation and diminished the rate of fixation failure. 6. All cases were achieved good to acceptable reduction. 7. Satisfactory functional results were achieved in 93.3%. 8. The rate of avascular necrosis was 15.4% (2/13 cases). It is concluded that the most of femoral neck fractures in younger patients occur because of the significant trauma. In our study, the incidence of avascular necrosis was not greater than in order patients. Therefore, to get as good a result as possible it seems important to perform the anatomical tion and rigid internal fixation with or without bone graft.

Therapeutic irradiation can induce angiosarcoma. Radiation-induced angiosarcoma constitutes 20% of all angiosarcomas. Although its common site of origin is the skin and subcutaneous tissue, it rarely arises in small or large bowels with a presentation as multifocal abdominal angiosarcomatosis. We report a case of intra-abdominal angiosarcomatosis involving the jejunum, ileum, transverse colon, mesentery and right ovary in a 63-year-old female. It developed 10 years after therapeutic irradiation for squamous cell carcinoma of uterine cervix. She developed panperitonitis due to intestinal perforation. She died from sepsis 3 days after segmental resection of the small bowel and right oophorectomy. We reviewed the previously reported cases and describe the clinicopathologic features of this tumor.

We performed inferior oblique myectomy or Z-myotomy on 159 eyes of 121 patients who showed inferior oblique overaction. And the results were as follows; 1. Success rates were 95.5% in myectomy and 71.4% in Z-myotomy. 2. Recurrence rates were 2.7% in myectomy and 14.3% in Z-myotomy. 3. There were no complications including adherence syndrome.

BACKGROUND: It is necessary for most effective treatment of neoplasms to detect it in early stage. For the purpose we use many screening tests currently, however, the tumor marker have many limitations as a screening test for neoplasm. Nevertheless most of Health screening centers are using CEA as a screening test for neoplasm. So, we began this study for the assessment of validity of CEA as a screening test for neoplasm. METHODS: The subjects were 4265 persons who visited Health screening center of Kyung hee Medical Center from July 1995 to June 1996. The number of elevated CEA among the subjects was 156. We evaluated the frequencies of factors known as etiologies of increased CEA. We followed up whether neoplasms were developed in normal CEA group. Through the random sampling of normal CEA group, 391 subjects were obtained for statistical analysis by SPSS/PC+. Immunoradiometric assay kit, of Eiken company was used for gauging CEA level and normal level was less than 2.4ng/ml according to manual of manufacturer. RESULTS: There was no significant difference of CEA according to sex, age. The factors that significantly affect CEA were neoplasms, chronic lung disease, liver cirrhosis. In t,his study, smoking, hypertension, diabetes mellitus, fibrocystic disease, chronic renal failure, alcohol drinking, hepatitis, peptic ulcer disease known as etiologies of elevated CEA in other studies did not show statistical significance. 9 cases of neoplasms were developed in both elevated CEA and normal CEA group during follow up. In former, 4 cases of 9 neoplasms were early stage. In latter, all cases were stage IV and inoperable. Specificity and sensitivity of CEA were each 96.5%, 50.0%. Positive & negative predictive value of CEA were each 5.8%, 99.8%. CONCLUSIONS: CEA was increased in various benign conditions and even if any neoplasm exists, CEA was not elevated in most of all in early stage. It showed high false positive rate and low sensitivity. Thus, this study showed that it was not valid to use CEA as a screening test for early detection of neoplasms.

Rat thalamocortical slices maintain synoptic connections between thalamus and cortex. When perfused with low Mg++-ACSF, thalamocortical slices exhibited two main types of spontaneous bursting activity. One is monotonic burst of 3-15 Hz and another is multiphasic bursts which have a tonic burst firing period and a late phase of clonic burst firing. These bursts are similar in frequency and during to EEG recordings from human generalized seizures. Exploiting the advantages of in vitro preparations, the electrophysiological action of taurine were studied. Exogeneous application of taurine profoundly decreased spontaneous bursting activities, which it caused only slight reduction of electrically evoked response in cortical layer. Taurine-induced current was blocked by 40 uM bicuculline, GABA receptor antagonist, in acutely isolated coritcal neurons. These results suggest that endogeneous taurine may regulate the hyperexcitablility through GABAa receptor.
