CT seans of 23 patients with gallbladder carcinoma were retrospectively reviewed to determine the incidence of lymphatic spread and to access the pattern of regional lymph node metastases. The lymphatic spread were noted in 74%(17/23). The involved patterns of regional lymph node metastases were nodes of porta hepatis 65%, portocaval nodes 41%, superior pancreaticoduodenal nodes 47%, posterior pancreaticoduodenal nodes 59%, nodes aroud the celiac trunk 35%, nodes around the superior mesenteric artery 29% and paraaortic nodes 35% The findings suggested that the pattern of regional lumph node metastases in gallbladder carcinoma occurred along the normal lymphatic pathway of the gallbladder.

Urinary tract infection in children is common and recurrent especially combined with anatomical and functional abnormalities, Radiological analysis of the 68 cases of urinary tract infection who were admitted to the pediatric department of Yong Dong Severance Hospital from Apr. 1983 to Aug, 1985 were subjected in this study. The results were as follows : 1. Urinary tract infection was more common in male under 1 year of age, but increasing with age more prevalent tendency in female. 2. Clinical manifestations on admission were fever, urinary frequency, flank pain, gross hematurea and etc. 3. Urinalysiss disclosed pyuria in 60 %, hematurea in 47 %, and bacteriuria in 7%. Escheridhia coli was the most common strain and Klebsiella species, Enterococcus, Proteus species were common in descending order. 4. In the radiologic findings, the patients of refluxed cases showed more changes in the size of kidney and damage of renal parenchyme. And also they were more combined with analtom cal abnormalities. 5.VCUG findings according to the grade of reflux showed more extensive changes of kidney itself, ureter and bladder with increasing of the grade of VUR. 6. Over 6 months follow- up , the initial scarring were aggrevated and getting worse although treatment.

Buerger 병

In Buerger's disease, angiographic findings are not pathognomonic , but in most cases they are diagnostic. We reviewed peripheral angiography of 36 cases of Buerger's disease who were suspected clinically during the period from Jan. 1979 to Dec. 1984. The results were as follows : 1. The sex distribgutionof the cases were 34 males and 2 females (17 : 1) and most common in 4 th decade. Eighty-six percents of the patients were smokers. 2. Chief complaints on admission were ulceration, pain at rest, coldness, and discoloration. 3. The anterior tibial artery was affected most commonly (88%) and posteior tibial(76%), peroneal (68%), popliteal (22%), and femoral artery (15%) in order. 4. The angiographic findings were 1) In all cases, there was abscence of arteriosclerotic lesions and showed smooth vessel walls in non-affected arteries. 2) Direct corkcrew type collaterals were found in 2% of the lesions, and indirect type collaterals in 81%. The tree-root or spider's leg type collat rals were also found in 74%. 3) Standing-wave patterns were found in 30% which affected above the popliteal artery. 4) Early venous drainage was found in 16% of the lesions.

Subdural hematomas are relatively common and the typical CT findings according to the age of them are well established. The CT findings of 82 patients with SDHs were reviewed and compared with the operative findings, RESULTS : 1. The most common cause of SDHs was the direct trauma which was noted in 60 cases. 2. The atypical CT findings of the mixed density were seen in 19 cass, including acute SDH 7 cases, subacute SDH 5 cases, and chronic SDH 7 cases. 3. The possible casuses of the mixed density in acute SDH were unclotted blood in early stage of hematoma development or serum extruded during the early phase of clot retraction. But the possibility of cerebrospinal fluid within subdural space due to an arachnoid tear could not be exclued. 4. The possible causes of the mixed density in subacute and chronic SDH were serum extruded during the hematoma resolution and rebleeding. 5. Wall enhancement of hematomas was notedin 3 cases of subacute SDHs and 15 cases of chronic SDHs. 6. ost of SDHs was crescentic in shape, but lenticular in 4 cases. Midline shift and compression of ventricles were proportional to the maximum thickness of SDHs. There were seen ipsilateral dilatation of ventricle in 9 cases and brain edema in 11 cases.

Trichomonas vaginalis is a parasitic flagellate found in the urogenital tract of humans. The present study was performed to evaluate the effect of antiserum from rat and rabbit on fine structure of T. vaginalis. Trophozoites were subcultured in TPS-1 medium(Diamond, 1968) at 37℃, CO₂incubator. T. vaginalis were inoculated in mixed medium containing of antiserum for 10 and 30 minutes, then observed with transmission and scanning electron microscope. The results are as follows: 1. T. vaginalis was ellipsoidal or ovoidal in shape with 4 flagella, an undulating membrane and an axostyle. The plasma membrane of body surface was smooth and furrowed. Pseudopodia(filopods) were often observed by SEM. Ultrastructure of trophozoites consisted of an elliptical shaped nucleus, RERs and Golgi complex around the nucleus, hydrogenosomes, glycogen granules, polysomes and vacuoles in cytoplasm. As the organelles for supporting and movement, an axostyle, kinetosomes, flagella, undulating membrane, costa and parabasal filaments were observed. 2. T. vaginalis treated with antiserum, its surface appeared destruction of plasma membrane, alteration and/or disappearance of axostyle, flagella and undulating membrane under the SEM and showed fine structural changes such as the nucleus surrounded by many vacuoles, decreased ribosomes, which attached to nuclear membrane and RER, vesiculated RER and Golgi complex. The area of filamentous cell coat and a number of coated vesicles were increased on plasma membrane with partial damage. According to going by the incubation time, the progressive destructions of cytoplasmic organelles, nuclear membrane, hydrogenosomal membrane, kinetosome and rootlet fiber were noted. With above results, it is presumed that specific antiserum induced the disturbance of protein systhesis and the damage of cytoplasm resulting lysis of T. vaginalis.

An echogenic lobulated round mass in the head of pancreas was found during abdominal ultrasonography for routine on a 34 vear-old man. CT and MRI showed characteristic findings of lipoma. Clinical followup confirmed intrapnacreatic lipoma, which had been reported only once proviously. This lesion should be added to list of benign connective tissue tumor of the pancreas.
