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.

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.

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

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.

BACKGROUND: It has been recognized for many years that myocardial infarction is almost invariably associated with significant narrowing of one or more coronary arteries. However, the widespread use of selective coronary angiography has resulted in an increasing number of reports of patients with proved infarction and patent coronary arteries. The purpose of this study was to analyze whether any clinical features distinguishes patients with these findings from those having coronary arterial lesions. METHODS: The clinical association of myocardial infarction with no significant stenosis of major coronary artery on cineangiogram was analysed retrospectively. The findings on the 13 patients in this group was compared with those of myocardial infartion with significant coronary artery stenosis. RESULTS: There were no significant differences in risk factors, hemodynamic findings of cardiac catheterization and the site of infarction between both groups. However, the patients with no significant stenosis of coronary artery had fewer complications during hospitalization and lesser ST segment change during exercise test before discharge. CONCLUSION: It could be concluded that the acute myocardial infarction with no significant stenosis of coronary arteries would have the better prognosis. The mechanism of the acute myocardial infarction with no significant stenosis of coronary arteries might be studied in the aspect of the coronary artery spasm and the alternation of function of endothelial cell.

Forty-four patients were operated on functioning pituitary adenomas during 5 years since Jun. 1977 at the Department of Neurosurgery, Seoul National University Hospital. Clinical and laboratory findings were analyzed and the following results were obtained. 1) The peak incidence was in the 3rd and 4th decade 21 cases were male and 23 cases were female. 2) Endocrinologic study revealed prolactinoma in 28 cases(37%), somatotropic adenoma in 13 cases(17%), corticotropic adenoma in 3 cases(4%), endocrine-inactive adenoma in 32 cases(42%). 3) MAin symptoms were endocrine symptoms(86%), headache(75%) and visual field defect(59%). 4) Seven(16%) were in the stage I(micro-adenoma), 27(61%) in the stage II, 6(14%) in the stage III, 4(9%) in the stage IV. 5) The rate of endocrinologic cure or improvement was 65% in prolactinoma and 75% in somatotropic adenoma. This result was less favorable less favorable than the result of other recent studies, but it seemed to be due to large proportion of large or invasive adenoma instead of micro-adenoma in this series. 6) In prolactinoma, 7 out of 12 patients with amenorrhea resumed menstrual cycle and 2 patients had pregnancies postoperatively. 7) The visual field defect was improved in 16 of 21 cases(76%) postoperatively.
