Differences in systolic time intervals(STI's) attributable to the types of mechanocardiographs used for their determinations were studied in a total of 341 healthy adult males. The STI's were measured from mechanocardiograms consisting of simultaneously rocorded electrocardiograms, phonocardiograms and carotid arterial pulse tracings obtained by each of three different types of mechanocardiographs in 125, 56 and 160 subjects, respectively. The study revealed that there were slight to considerabe differences among the three groups in the correlation coefficients between the individual STI's and heart rate. Thus, regression equations using heart rate as variables, for those STI's which were significantly correlated with heart rate, differed slightly to considerably among these groups. In addition, the mean values of those STI's and their derivatives, which showed no significant correlation with heart rate, were also silghtly or significantly different among the three groups. These findings suggest that if STI's obtained from patients are to be adequately evaluated at all, each laboratory must define its own normal standards worked out by using its own methods of recording and analysis of the mechanocardiogram, and cannot rely on those proposed by others.

There are many procedures described for the treatment of acromioclavicular seperation but there are still controversies concerning the best management of these injuries. Thirteen cases were operated on by technique of modified Phemister method and four cases by Bosworth method, Dept. of Orthopedic Surgery, Chonbuk National University Hospital from January 1980 to December 1984. The following results were obtained. The following results were obtained. 1. This injuries is more prevalent in male (76.4%) with peak incidence in the second, third and fourth decades(76.4%). 2. The most common causes of the injuries were traffic accidents and followed by falling from the height. 3. Fifteen patients were grade 3 by Allmans classification. 4. Operative method consists of modified Phemister method (76.4%) and Bosworth method (23.6%). 5. The operative procedures in Type 2 and Type 3 are good treatment of acromioclavicular seperation.

CD44v6 was known as tumor marker for tumor progression and metastasis in various kinds of carcinomas. The CD44v6 monoclonal antibody was produced by cell cultures or mouse ascite fluids using CD44v6 hybridoma cells, and its immunogloburin G (IgG) was purified by Protein A column. Using immobilized ficin and cysteine, the antibody fragment Fab was produced and purified by Protein A. Four CD44v6 scFv molecules were produced from the recombinant DNA and phage antibody technology and prurified by His-tag affinity chromatography. In order to inspect the function and specificity of each antibody molecule, western-blotting and ELISA against CD44v5-6 recombinant proteins and irnmunodetection in human ovarian carcinomas were estabilished. The results showed that immunodiagnosis did not distinguish the types of antibody fragments, but western-blotting and ELISA results did show some difference of their specificities and biological properties. These studies will contribute as a model study for the immunodiagnosis and therapy using the IgG, Fab and scFv of CD44v6 antibody to obtain the early detection of tumor progression and metastasis using immunoscintigraphy.

A case of primary amelanotic melanoma of the vagina diagnosed in scraping smear is described. A 64-year-old woman complained of vaginal bleeding with a 2.5x2cm sized, fungating mass on the right lateral vaginal wall near the introitus for 2 months. Scraping smears from the mass showed scattered individual tumor cells with single, bi- or multi-nucleated eccentric nuclei having prominent macronucleoli and occasional intranuclear inclusions. The cytoplasm was plump and cyanophilic with a indistinct rim. No melanin pigment was identified. Characteristic cytologic features of this case were very helpful to exclude more common squamous cell carcinoma in the vagina, which was strongly suggested in biopsy specimen.

BACKGROUND: The induced hypotensive anesthesia may produce serious complications related to central nervous system, heart, liver, kidney and eyes. In this study, the blood loss during and after operation were compared to evaluate the delayed effect of hypotension on postoperative bleeding and also, the urine output was measured in control group and furosemide treated group, to investigate the effect of furosemide on the protection of kidney function. METHODS: Forty patients undergoing spinal surgery were evaluated and the hypotension was induced by the combination of hydralazine, esmolol and propranolol under enflurane anesthesia. During hypotensive anesthesia, the systolic arterial blood pressure was maintained between 65 to 75 mmHg. I compared the arterial blood gas analysis, plasma protein, albumin and calcium level, blood urea nitrogen (BUN), creatinine and complete blood count (CBC) before, durng and after hypotensive anesthesia. And also, the volume of blood loss and the units of transfused blood were measured intraoperatively and postoperatively. To investigate the effect of furosemide on the protection of kidney function, patients were randomly divided to contol group (n=20) and furosemide group (n=20). In furosemide goup, 0.1 mg/kg was administered intravenously and the urine output was measured during and after hypotensive anesthesia in both groups. RESULTS: The systolic arterial blood pressure during hypotensive anesthesia was maintained between 65 to 75 mmHg as planned in all forty patients. The average blood loss during and after operation were 769+/-541 and 786+/-397 ml, respectively and the average total blood loss was 1555+/-784 ml. The average units of transfused packed red cell during and after operation were 2.6+/-0.8 and 1.9+/-0.4 units, respectively, and the average total transfused units were 2.3+/-0.8 units. In both control and furosemide treated groups, all forty patients showed oliguria during first two hours after starting hypotensive anesthesia but urine outputs were recovered after the end of hypotensive anesthesia in both groups. During and after hypotensive anesthesia, pH was slightly but significantly decreased. Plasma protein, albumin, calcium and BUN were decreased during and after hypotensive anesthesia compared with before hypotensive anesthesia values. During and after hypotensive anesthesia, platelet count was decreased significantly but white cell count was increased. Severe oliguria was noted during hypotensive anesthesia in both groups and no serious complication related to hypotensive anesthesia was found. CONCLUSIONS: In this study, the volume of blood loss after anesthesia was almost same as that during anesthesia. And the administration of furosemide 0.1 mg/kg did not prevent oliguria during hypotensive anesthesia.

Focal dermal hypoplasia (Goltz syndrome) is a rare genetic mesoectodermal disorder characterized by variable multisystem defects, including anomalies of the skin, skeleton, teeth and eyes. A 22-year-old female patient presented with confluent and disciete, yellowish nodules on the calves, white linear atrophic lesions, hypoand hyper!igmented patches, and telangiectasia scattered over the trunk, neck and extremities. In addition to the skin lesions, this patient showed hypertrophy of the left leg, anomalies of the left foot, fingers and nails, and maloccluded teeth. Histopathological findings of a yellow nodule revealed accumulations of adipose tissue very near to the epidermis that largely replaced the upper dermis.
