To evaluate the diagnostic findings of salivary gland tumors, we reexamined aspiration cytology smears of 7 cases of pleomorphic adenoma, 3 cases of adenoid cystic carcinoma, and 3 cases of mucoepidermoid carcinoma, performed during April 1986 to March 1990, which were com?med by surgical excision and histologic diagnosis. The results obtained are summarized as follows ; 1. All cases of pleomorphic adenoma showed branching cellular clusters of epithelial and myoepithelial cells. Acellular elements including myxomatous and chondroid components were observed. There were no cellular pleomorphism and nucleoli. Keratinizing squamous epithelial cells and keratin pearls were noted. 2. The smears of adenoid cystic carcinoma showed cell balls or cell cords containing a central hyaline core. Nuclear atypism and the nucleoli were frequently observed. There were no keratinizing squamous epithelial cells. 3. The smears of mucoepidermoid carcinoma showed mainly sheets or clusters of intermediate cells and some mucin-producing cells. Some nuclear pleomorphism was observed. Mucinous material and many inflammatory cells were present in the background.

We have experienced a case of pericardial tuberculoma, a very rare disease, with massive pericardial effusion in a 63-year-old veteran. He wdimensional echocardiography. Computed tomographic scans confirmed the presence of a pericardial mass and clinically unsuspected "lung mass". The presence of the lung mass led us a diagnostic and therapeutic dilemma. Surgery confirmed the pericardial mass which revealed tuberculosis by patholohy and loculated pleural effusion at the major fissure, so-called "phantom tumor", not a lung mass.

This study was designed to evaluated the effects of opioid receptor agonists on the spontaneous alternation behaviour in an animal model of obsessive-compulsive disorder in rats. According to the theory that dopamine is related to the biological etiology of obsessive-compulsive disorder, the effect of the nalbuphine(opioid kappa agonist) and the tramadol(opioid mu agonist), which act as manipulating agents on the inhibition or stimulation of dopamine release, in the spontaneous alternation behaviour were evaluated. 24 hours prior to the experiment, rats were food-deprived. These rats were put into the T-maze, in which white and black goal boxes were baited with small amounts of chocolate milk. Each rat was given 2 set of 7 trials during which it was placed in the start box and allowed to choose the one of the goal boxes for each time. After identifying the stable baseline of spontaneous alternation behaviour, nonselective 5-HT agonist 5-MeODMT(1.25mg/kg/IP) disrupted spontaneous alternation. Rats were stratified into fluoxetine(10mg/kg/IP), nalbuphine(10mg/kg/IP), tramadol(46.4mg/kg/IP), and saline(0.5cc/IP) injection group with experimental drug treatment for 21 days. The effects on the 5-M?DMT(1.25mg/kg/IP) induced disruption of spontaneous alternation behaviour were checked at the next day of discontinuation of drug treatment. The results were as follows : 1) At the day after 21 days of the drug treatment, the nalbuphine treated group and the fluoxetine treated group showed significant difference from the tramadol treated group and the saline treated group in the 5-MeODMT(1.25mg/kg/IP) induced suppression of spontaneous alternation behaviour. 2) Within each drug treatment group, the fluoxetine treated group showed significant difference between before and after the treatment of fluoxetine in the 5-MeODMT(1.25mg/kg/IP) induced suppression of spontaneous alternation behaviour. And also, the nalbuphine treated group showed significant difference between before and after the treatment of nalbuphine in the 5-MeODMT(1.25mg/kg/IP) induced suppression of spontaneous alternation behaviour. There was no difference between the baseline and after the treatment of nalbuphine in the 5-MeODMT(1.25mg/kg/IP) induced suppression of spontaneous alternation behaviour. We indentified that the opioid kappa agonist that act as dopamine release inhibitor affect the spontaneous alternation behaviour which is an animal model of obsessive-compulsive disorder in rat.

Suicide through naphthalene poisoning is rare. Prolonged hemolytic anemia and hemoglobinuria are typical symptoms of naphthalene poisoning. We report an unusual case of naphthalene poisoning. The decedent was an 87-year-old female who intentionally ingested over 5 g of naphthalene. After more than 5 hours, she was found in a drowsy state. During initial examination, hemoglobin level and urine test results were normal. Aspartate aminotransferase and alanine aminotransferase levels were elevated (854 and 1,197 U/L, respectively). Metabolic acidosis was found on arterial blood gas analysis. The patient was treated conservatively by administration of activated charcoal, calcium gluconate, insulin, and glucose. However, the patient died after 1 day of hospital admission. On autopsy, the liver showed toxic hepatitis with confluent necrosis. Naphthalene concentrations in the blood and gastric contents were 5.4 and 5.8 mg/L, respectively. In conclusion, the decedent ingested naphthalene and died due to liver failure without hemolysis.

We experienced a case of vitamin B12 unresponsive methlymalonic acidemia in a 4 day old female, who had poor feeding, dehydration with metabolic acidosis, and hyperammonernia and died at 7 days of age. Diagnosis was made by gas chromatography and mass spectrometry, and this case is probably a methylmalonyl CoA mutase apoenzyme deficiency type.

A clinicopathological study was made on 17 case with leukemia cutis diagnosed in a period of 10 years frorn 1980 to 1989 in Seoul Xational University I-lospital. The results were summarized as follows : 1. There were 4 cases with acute lyrnphocytic leukernia, 7 with acute myelocytir. leukemia (AML), 5 with chronic myelocytic leukemia (CML), 1 with eosinophilic leukemia. 2. The clinical appearance of leukemia cutis included nodules (88.2%), papules, macules, plaques and ulcerative lesions. Leukemia cutis dis not show any discernible clinical qppearance with each different type of leukemia. 3. Leukemia cutis showed a wide spectrum of histopathologic features, diffuse infiltration, patchy infiltration with linear infiltration between collagen bundles, perivascular and peridnexal involvement, perivascular involvement, and mainly subcutaneous tissue involvement. There was no distinctive histopathologic pattern with each different type of leukemia. 4. The demonstration of intracytoplasmic chloroacetate esterase and lysozyme was helpful to refine the diagnosis of leukemia cutis.

The authors measured the lateral & 3rd ventricles and cortical sulci in computerized axial tomographic films of 15 male patients with chronic alcoholism and 16 controls, who had been admitted to Kyng Hee University Hospital from Jan. 1, 1979 to Mar. 31, 1983. The results were as following: 1. The average age of patients was 47.5 yrs., and that of conntrols was 34.5 yrs. The average duration of habitual drinking was 11.6 yrs., and complicated with delirium tremens, head trauma, liver diseases (46.7% each other) and seizure (33.3%). 2. The sulcal widening was found in 9 cases (60.0%) of patients (mean +/- S.D. = 6.7 +/- 1.76mm) and no cases in control group (mean +/- S.D. = 2.3 +/- 0.88mm). The difference between patients and control group was statistically significant, especially in twenties (P<0.05). 3. The lateral ventricular enlargement was seen in 12 cases (80.0%) of patients (mean +/- S.D. = 17.1 +/- 0.93mm), and 8 cases (50.0%) of control group (mean +/- S.D. = 14.7+/- 1.46mm). There was statistical significance, especially in forties (P<0.05). There were no statistical significance except cella media index (P<0.05), according to various measuring indices. The width of 3rd ventricle was 1.88 +/- 0.152mm (mean+/-S.D.) in patients and 1.12+/-0.311mm (mean +/- S.D.) in control group. And the difference was statistically significant. 4. Cerebral atrophy was noticed in 10 cases (67.0%) among 15 taken C.A.T. of brain.
