Although measurement of cerebral blood flow by radioactive - isotope method became popular, there is still no report of study on the cerebral blood flow in Korea. Auther studied the regional cerebral blood flow in 28 normal Korean adults and and 76 patients including 14 cases of essential hypertension, 11 cases of heart diseases (coronary artery disease, valvular diseases and A-V block), 14 cases of brain diseases(cerebral thrombosis and cerebral insufficiency), 22 cases of head trauma and 15 cases of miscellaneous medical diseases. The regional cerebral blood flow was measured by intravenous in jection of (99m)Tc-DTPA 15-20Ci and by taking serial cerebral angiograms with CGR Gamma Tome 7000 and was analized by computer Imac 7310. The results were as follows: 1) The average regional cerebral blood flow of normal Korean adult was 50.0+/-5.89mg/100g /min. with range of 41-60ml/100g/min. 2) In most cases of essential hypertension the regional cerebral blood flow was within normal limit except rare case which was considered to have impaired autoregulation of cerebral blood flow. 3) In patients with myocardial infarction, valvular heart diseases with congestive heart failure and complete A-V block, there was markedly reduced cerebral blood flow. The reduced cerebral blood flow increased after the improvement of congestive heart failure and after the implantation of pacemaker. 4) In patients with cerebral thrombosis with infarction and cerebral insufficiency with symptoms of dizziness, headache or blurred vision, the cerebral blood flow was considerably reduced. However in acute encephalits the cerebral blood flow was increased. The measurement of cerebral blood flow by radioactiveisotope method is considered to be accurate, easy and useful clinical test to evaluate brain diseases and function.

PURPOSE: Laparoscopic nephrectomy has become accepted as a method of simple nephrectomy replacing with open nephrectomy in patients in whom a kidney requires removal for benign disease. Laparoscopic nephrecto my is widely performed and extends its indications. We evaluated our experience with the laparoscopic nephrectomy to assess the clinical efficacy. MATERIALS AND METHODS: Between April 1996 and September 1999, 23 patients (7 men and 16 women, mean age 44.1 years old) underwent laparoscopic nephrectomy, 16 by women, mean age 44.1 years old) underwent laparoscopic nephrectomy, 16 by the transperitoneal approach and 7 by the retroperitoneal approach. Operative and clinical records were reviewed. The underlying pathological conditions included 20 cases of non-functioning kidney, 2 cases of hypoplastic kidney with complete duplication and ectopic ureter, and 1 case of ureter tumor. Four ports (21 cases, two 12mm ports and two 5mm ports) or 5 posts ( 2 cases, two 12mm ports and three 5mm ports) were used. RESULTS: The laparoscopic procedure were successful in 20 cases (87%). Three patients had open conversion due to unclear anatomy, severe adhesion, and adrenal bleeding. In successful cases, mean operative time was 253+/-83 minutes (range 140-545), mean hospital stay was postoperative 5.2 days. Intraoperative and perioperative complications were noted in 6 patients, including bleeding requiring transfusion in 3, wound infection in 1, severe subcutaneous emphysema in 1, diarrhea in 1. CONCLUSIONS: Laparoscopic simple nephrectomy is feasible, effective, and safe treatment option. It is a less invasive alternative to open surgery providing a more rapid recuperation and superior cosmetic effect.

BACKGROUND: The relationship and differentiation among various dendritic cells of the dermis are unclear. Recently it has hecome possible to identify different subpopulat,ions of dermal dendritic cells using anti-CD34 and anti-factor XIIIa antibodies. OBJECTIVE: To elucidate which cell types the fibrous dermal turnors consist of we compared the staining patterns of these antibodies as well as of anti-Mac 387 antibody which are labeled as inflammatory cells of the monocyte-macrophage lineage. METHODS: Tumors studied included dermatofibrosarcoma protuberans(DFSP, n=2), dermato-fibroma(n=22), neurofibroma, n=27), acrochordon(n=15), keloid, hypertrophic scar(n=10), juvenile xanthogranuloma(n=1, and malignant fibrous histiocytoma (MFH, n=1). We performed immunoperoxidase staining(AUSC technique) with polyclonal anti FXIIIa antibody, monoclonal anti-CD34 antibody, and monoclonal anti-Mac 387 antibody on the formalin-fixed-paraffin-embedded tissue specimens of these fibrous tumors. The intensity of staining was graded as negative, weakly staining, or strongly stainiring. RESULTS: FXIIIa reactivity was strongly present in dendritic and spindle-shaped cells of all dermatofibromas and some nurofibromas(11 of 27 specimens), but absent from the other fibrous tumors. Among these tumors, one of the two DFSPs was uniquely expressed CD34. Dendritic and spindle-shaped cells within tiese tumors were MAC 387 negative. In inflammatory conditions, variable numbers of MAC 38 positive cells were observed, corresponding to histiocytes and mac-rophages, but the labeling of ipithelioid cells and multinucleated foreign body giant cells were variable. CONCLUSION: The findings of significant numbers of FXIIIa positive cells in dermal fibrous tumors studied suggest that thet may be diagnostic utility associated with the use of this antit)ody. In addition, CD 34 expression by the tumor cells can be an extremely useful marker in establishing a definitive diagnosis of IFSP.

The effect of diphenylhydantoin on LD 50 of ouabain was investigated in frogs, using "one hour frog method". LD50 of ouabain in control group was 1.90 microg/10g. A dose of 100 microg/10g diphenylhydantion did not affect the systemic manifestations of the frogs, but increase the LD50 of ouabain to 2.60 microg/10g. The difference of LD50 of ouabain and potency ratio between control group and diphenylhydantoin-treated group was statistically significant.

Condyloma acuminatum occurs in perianal and genital area by infection of human papillomavirus (HPV) and appeais as fairly soft verrucous papules or a cauliflower-like mass. So far 60 HPV types have been identified. Among them, condyloma acuminatum is predomi-nantly associated with HPV 16, 18 and rarely with 16, 18. HPV 16, 18 is regarded as a high-risk HPV infection because of the association of HPV 16, 18 with Bowens disease, cervical cancer, and anogenital cancer. In additioin, a significant appearance of cervical anaplastic lesions is preceded by condyloma acuminatum and a high prevalence of cervical dysplasia has been found in female consorts of men with geriital warts. Malignant transformation has been observed in rare incidences of condyloma acumina a on the external genitalia. We present a case of condylc ma acuminatum showing malignant transforrnation. The patient also has uterine cervical carcinonia. We detected HPV 16 in the lesion using polymerase chain reaction.

Effectiveness of the video-record learning method in teaching bowel elimination nursing skill was investigated using an experimental research methodology. Data was collected from 63 female students attending Fundamental Nursing class from a nursing college in Seoul. The subjects were randomly assigned to two groups, one is the experimental group of 29 and the other the control group of 34. The independent variable was video-record learning method and the dependent variable were the degree of knowledge achievement, nursing skill achievement, competence on practicing elimination skill, and satisfaction about the learning method. The hypotheses of the study were as following. 1) There will be significant difference between the experimental group and the control group in dependent variables. 2) There will be significant positive correlations between nursing skill achievement and other three dependent variables-interest in nursing, adaptation in nursing, and preference of nursing job. Data was analyzed using descriptive statistics, chi-square test, t-test, and Pearson's correlation coefficient with SPSS PC+ program. Findings of the study are: 1) There was no significant difference between the experimental group and the control group in knowledge achievement using P<.05. 2) There was significant difference between the experimental group and the control group in nursing skill achievement using P<.05. 3) There was no significant difference between the experimental group and the control group in competence on practicing elimination skill using P<.05. 4) There was no significant difference between the experimental group and the control group in satisfaction about learning method using P<.05. 5) There was positive correlation between nursing skill achievement and the other variables but no significant difference was shown. 6) This study suggests that video-record learning method is an effective learning method for achieving basic nursing skills but is not effective in other areas such as knowledge achievement, competence in performing nursing practice, and satisfaction about the learning method. Further study with more developed research design and statistical analysis should be done to investigate the effectiveness of video-record learning method in learning basic nursing skill more accurately.
