Computed body tomography has become useful in the diagnosis of pancreatic disease. It was found to be are liable, often specific, and noninvasive method for detecting pancreatitis and extra-pancreatic extension of the pathology. Of eight hundred and seventy-two cases studied for abdominal pathology with EMI-CT 5005 whole body scanner form Oct. 1977 to August 1980, 21 cases were confirmed to be pancreatitis clinically or operatively. The authors reviewed the CT findings of the above cases and the results were as follows; 1. Among twenty-one cases, the acute pancreatitis was 12 cases and the chronic pancreatitis was 9 cases. The sex ratio as 17 males to females. 2. In acute pancreatitis, diffuse enlargement of pancreas (11/12), focal enlargement (1/12), loss of peripancreatic fat plane (9/12), thickening of anterior of pararenal fascia (6/12), and smooth margin ofpancreas (5/12) were observed. 3. In chronic pancreatitis, parenchymal atrophy (7/9), normal size (2/9), loss of peripancreatic fat plane (3/9), thickening of anterior pararenal fascia (1/9), calcification (1/9), smooth margin (2/9), and serrated margin (6/9) were observed. 4. The complications were associated with 7 cases of acute pancreatitis and 1 case of chronic pancreatitis; pseudocyst (6), abscess (2), and fat necrosis (3), The sites of the pseudocyst were lesser sac (2), anterior pararenal space (2), posterior pararenal space (1), subhepatic region (1), greater omentum (1), and intrapancreatic region (2). All of them were associated with acute pancreatitis except one in chronic pancreatitis.

To evaluate the differentiation status of smooth muscle in gastric stromal tumors which were negative for S-100 protein, immunohistochemistry using desmin, actin, myosin and vimentin was performed in 14 cases of gastric smooth muscle tumors. Ultrastructural Examination was also performed. For comparison a case of leiomyoma of the esophagus, a case of the sigmoid colon, 10 cases of the uterus were also examined. The results obtained were as follows. All gastric smooth muscle tumors showed vimentin-positivity. Six of 14 gastric smooth muscle tumors, (5 of 8 leiomyoma and 1 of 4 leiomyosarcoma) showed positivity for desmin, actin, and myosin(42.9%). All esophageal, colonic, and uterine leiomyomas showed diffuse positive reaction for desmin, actin, and myosin. Vimentin positivity was also noted in leiomyoma of the colon and uterus. Ultrastructurally, a few cells in the gastric stromal tumors had scattered microfilaments with dense bodies, subplasmalemmal dense plaques, and micropinocytic vesicles. However, most of the tumor cells did not have any of the ultrastructural features of smooth muscle differentiation. Leiomyomas of the esophagus and uterus showed many cytoplasmic microfilaments with dense bodies. These results suggest that most of the benign and malignant tumor cells of gastric stromal tumors have features of the undifferentiated cells, immunohistochemically as well as ultrastructurally, although a few cells have. It is speculated that most gastric stromal tumors may have lost their smooth muscle differentiation.

The infantile polycystic kidney disease is rare fetal urinary tract anomaly. It is inherited with an autosomal recessive pattern and recurrence rate is 25%. The gene locus is on chromosome 6p. The pathogenesis of infantile polycystic kidney is the primary defect of the collecting ducts. The ultrasonographic finding of infantile polycystic kidney is oligohydramnios, bilaterally symmetrical enlarged kidneys with maintenance of their reinform shape. The differential diagnosis with adult polycystic kidney disease is important. The massive enlargement of the kidneys is rarely seen in adult polycystic kidney disease and the examination of the parents and other members of the family is helpful to confirm the adult polycystic kidney disease. If there is severe renal involvements, stillbirth or neonatal death secondary to pulmonary hypoplasia would be developed. If it were diagnosed before viability, termination of pregnancy is recommended. In a fetus at risk, diagnosed after viability, pregnancy termination is also recommended since this condition is uniformly fatal. We present a case of infantile polycystic kidney.

Neuroglial cells are actively participate in the pathogenesis or in the recovery procedures following brain lesions. The study was performed to evaluate the plasticity of glial cells following different degree of brain lesions. Neurosurgical operations were made on the rats fixed on the stereotaxic apparatus. Tissue column of 3 mm-diameter was isolated in the caudatoputamen with concomitant severe bleeding in the first group. In the second group, the sensorimotor cortex was suctioned out with moderate bleeding. In the third group, the mammillary body was electrically coagulated with minimal bleeding. Caudatoputamens, as a lesioned tissue or as a target tissue of lesioned area, were studied light and electron microscopically. Observations on reactivities and plasticities of neuroglial cells on the different situations, the following results were obtained : 1. Astrocytes were swollen within an hour following brain lesions. 2. In case of smaller lesion, astroglia alone remove altered structures. 3. Microglia are increased in number, if the lesion is large with severe bleeding. The microglia might come from blood monocyte via transformation to pericyte. 4. In large lesion, astroglia were greatly hypertropied, and microglia might be moving and functioning effeciently within the hypertropied cytoplasm of astroglia. 5. In the stabilizing stage, astroglia produce glial fibers and fix the exhausted microglia. Fixed microglia are proceed into apoptotic process in the cytoplasm of astroglia and removed by them. All these procedures might be controlled by various receptors and secretions of astroglia. It means that astroglia is not only the basic supporting element of nervous tissue, but also an actively functioning element for the most effective homeostatic functioning of the neuropil.

The non-metric analysis of the skulls is very useful for estimating sex and determination of ancestry, the accuracy tends to depend on the amount of experiences of the observers, and so inter-observer errors might be happened. Many researchers are trying to find out more objective methods for determination of ancestry. The purpose of this presentation is to show the usefulness of moire contourography for analyzing the skull. The master screen that is similar to the gratings was made by steel rods, which were arranged as equally spaced parallel lines. Halogen light source was illuminated by lantern slide projector. The skeletal materials were documented crania, composed of 87 male and 47 female, from William M. Bass Donated Skeletal Collection housed at the Department of Anthropology, University of Tennessee. The skulls were placed just behind the master screen as anatomical position using cubic craniophore. The angle between the light source and camera was 65degrees, the distance between camera and the master screen was 1.2 m. Frontal view, left lateral and right lateral view were taken. From the frontal view, fringe patterns were analyzed for first five contour lines which were mainly located around the Glabella. The results were as followed; Type I for male was 53% and female was 4%; Type II for male was 29% and female was 2%; Type III for male was 2% and female was 15%; Type IV for male was 6% and female was 55%. From the lateral view, fringe patterns were analyzed for first four contour lines. However, first and second contour lines were critical to determine the shape and the results were as followed; Type I for male was 52% and female was 22%; Type II for male was 38% and female was 26%; Type III for male was 8% and female was 17%; Type IV for male was 2% and female was 35%. According to this study, different fringe patterns might be dependent on the degree of development of bone marker such as Glabella, Supercillary arch, Euryon and Mastoid process. For example, Supercillary arches were very well developed and slope of forehead above the Glabella was declined, fringe pattern showed reverse triangle shape. If Supercillary arches were poorly developed and slope of forehead above the Glabella was flat, fringe pattern showed home plate shape. The present research shows that moire contourography might be used as more objective methods for estimating sex. And it would be helpful to determine the ancestry when the lateral aspects were analyzed. In the future, continuing study need to be performed with same master screen for different ancestry.

OBJECTIVES: To determine if hysterectomy with or without ovarian preservation is asso-ciated with obesity in premenopausal women. METHODS: 581 women for routine check up from Jan. 1985 to Dec. 1995 in the depart-m ent of Gynecology at Korea Veterans Hospital were included. The obesity was evaluated by BMI(body mass index) scores. 80% of hysterectomy were confirmed from the hospital records. The age, weight, height, blood pressure, menstr- ual history, history of DM and hypertension, social history of alcohol and smoking and other cardiovascular risk factors such as cholesterol, HDL-cholesterol, triglycerides were checked. The 248 women with natural postmenopausal status before hysterectomy, taking hormonal replacement therapy after hysterectomy and having performed hysterectomy due to malign- ancy were excluded. RESULTS: All women performed hysterectomy were in premenopausal status in this study. Therefore, the final numbers of subjects included in the analysis was 333. Hysterectomy wit- hout ovarian preservation were performed in 58 cases and hysterectomy with ovarian pres- ervation were in 57 cases. The 218 premenopausal cases which did not performed hystere- ctomy were considered control group. BMI scores were higher in cases without ovarian pres- ervation than with ovarian preservation. And BMI score was associated with the postoper- ative duration in hysterectomy with ovarian preservation. CONCLUSIONS: We suggest that hysterectomy without ovarian preservation in premeno- paussal women were associated with increased obesity, especially BMI scores.
