In an attempt to evaluate the immune competence of urologic cancer patients, antibody-dependent cell-mediated cytotoxicity (ADCC) were performed in thirty-four patients and same numbers of age and sex matched normal controls. Also we compared of the level of ADCC before and after the operation. Concomittantly the values of ADCC were examined by histological grading and clinical staging. We used 51Cr-labelled chicken erythrocytes sensitized with 7s rabbit anti-chicken erythrocytes antibody as target cells and patient peripheral mononuclear cells as effector cells. 1. Effector cells of the patients with the urologic cancer showed significantly lower ADCC than those of normal controls. 1) All urologic cancer. Controls 41.4+/-6.0% (n=34) Preoperation 22.1+/-6.8% (n=34) 2) Transitional cell carcinoma of the renal pelvis and the bladder. Controls 41.7+/-6.1% (n=28) Preoperation 22.5+/-6.3% (n=28) 3)Non-transitional cell carcinoma(renal cell Ca. prostate ca. penis ca. seminoma). Controls 40.2+/-5.9% (n=6) Preoperation 20.6+/-4.6% (n=6) 2. In the patients with the transitional cell carcinoma of the bladder and the renal pelvis, highly graded patients had tendency to have lower response of ADCC. Grade I 27.3+/-4.0% (n=14) Grade II 19.9+/-4.l% (n=7) Grade III 15.5+/-3.2% (n=7) 3. In the patients with bladder carcinoma highly staged patients had tendency have lower response of ADDC. Stage T

A clinical review was performed in 52 cases with the foreign body in the gastrointestinal tract who underwent the endoscopic extraction of fereign body at our hospital from June 1985 to October 1989. The results are as following. 1) The most prevalent age was under 10 years of age (21 cases, 40.4%), and male was more prevalent than female (M:F=1.6:1). 2) The most common site of foreign bodies was esophagus (35 cases, 67.3%), next stomach (15 cases, 28.9%). 3) The foreign bodies in esophagus were coins (18 cases, 51.4%), meats (7 cases, 20.0%), bones (5 cases, 14.3%), other food materials or metals (5 cases, 14.3%)in order of frequency, and those in the stomach wer bezoars (7 cases, 50.0%), coins (2 cases, 14.3%), suture materials (2 cases, 14.3%), others (baduk stone, pin, tack, cross). 4) The combined diseases with upper gastrointestinal foreign bodies were the passage disturbances (11 cases, 21.2%) due to stenosis, and schizophrenia (1 case), aleoholism (1 case). 5) Complications by foreign bodies were 8 cases (15.4%), such as eisophageal laceration or ulceration (4 cases), esophaigeal perforation (1 case), aspiration pneumonia(1 case), duodenal obstruction (2 cases). 6) Successful rate of the endoscopic extraction was 88.5%(46 in 52 cases). And 6 unsuccessful cases were 4 cases who have gastric bezoars too hard and large to extract, a case with esophageal perforation, and a case with bezoar in the third portion of duodenum.

The authors report our experiences with the use of Nd-YAG laser in extripation of selected intracranial tumors:5 Meningiomas, 1 Acoustic neurinoma, 1 Hemangioendothelioma and 1 Oligodendroglioma. The Nd-YAG laser is very helpful to coagulate the pathologic vessels. And because of it's excellent coagulation the Nd-YAG laser is particularly useful when applied in highly vascular tumor as well as in high contents of mesenchymal structures within the tumors.

Masson's hemangioma is a rare benign vascualr condition with a papillary intravascular endothelial proliferation which may appear either as aprimary form or as a secondary form in a pre-existing vascular process.CT and angiographic features of 2 cases with Masson's hemangioma were presented. Both of them were locatedextra-axially in the posterior fossa. CT findings were not specific in both cases: One showed homogeneously enhancing mass, simulating meningioma. And the other demonstrated a multiolocular rim enhancing mass. However, the angiographic features were rather characteristic; Both cases showed persistent vascular poolings of contrast mediawhich were supplied form the meningeal vessels. Angiographic differential diagnosis of similar lesions in theposterior fossa is discussed.

Two cases of Sturge-Weber disease in a 10 years old female and a 7 years old male were prese-nted. The diagnosis was established by charactristic features of Sturge-Weber disease including facial port-wine nevus, convulsion, typical ???ailread track pattern intracranial calcifications, some degree of mental retardation and hemiplegia. A brief review of related literature was made.

While posttraumatic occlusion of the extracranial carotid and vertebral arteries is well known, reports of occlusion of intracranial vessels following closed head injury are rare. Since Deveer and Browder reported the first case in 1942, only 22 cases of posttraumatic middle cerebral artery occlusion have been reported until now. We experienced 2 cases of posttraumatic middle cerebral artery occlusion recently. One patient was 27 years old male who developed right hemiplegia after relatively minor head injury. Reported angiograms taken on the 13th day after trauma revealed sparse middle cerebral artery branches with retrograde filling through left anterior cerebral artery in middle cerebral artery territory. He showed relatively satisfactory recovery by conservative treatment with steroid and cerebral vasodilator. The other patient became semicomatous with left hemiplegia after fall down accident from running train. Left carotid angiograms showed complete obstruction of left middle cerebral artery in its initial portion with corresponding avascular area. This patient died one week after the angiography in spite of all possible conservative care.
