Angiosarcomas are rare tumors, seen most commonly in the skin and soft tissue of head and neck region. But it has been described in numerous body sites including thyroid, breast, liver, spleen, bone, etc.. Their biological behaviors depend on the microscopic grade, site of origin, and multifocality. We report the unique cytological features of an angiosarcoma in pleural fluid. A 61-year-old woman presented with a 6 month history of dyspnea on exertion and chest pain. Chest computerized tomography(CT) revealed multiple subpleural small nodules in the right lung and widespread air space consolidation and pleural effusion in the left lung. CT of liver revealed multiple small low attenuated lesion. The smears obtained from pleural fluid showed hypocellularity with a hemorrhagic background. The tumor cells were highly pleomorphic oval or spindle in shape and presented singly, in loose groups, in knitted syncytial aggregates, and in acinar pattern. Their nuclei had vesicular chromatin with delineated, thick nuclear membranes and occasionally a large eosinophilic, prominent nucleolus. The cytoplasm was plump, thin or projected in spindly fashion. Almost all tumor cells showed variable sized intracytoplasmic vacuoles and their nuclei were sometimes crescentic by a huge vacuole. Occasional binucleated tumor cells and mitotic figures were present. Cellular debris and streaky materials were identified. Needle biopsy specimen from the pleura revealed anastomosing slit-like spaces lined by pleomorphic tumor cells. The tumor cells showed a strong reactivity for CD31 and vimentin and focal weak reactivity for factor VIII-related antigen.

PURPOSE: The purpose of this study was to examine the effects of a stress management program on mental health and coping behavior for children of alcoholics. METHOD: Data was collected from January to February, 2003. The subjects were 20 adolescents from 13 to 18 years old. Data was analyzed using descriptive statistics, chi-square test, and t-test with the SAS program. RESULT: There were statistically significant differences in mental health, active coping, positive cognitive restructuring, and support-seeking for problem solving between the experimental group and the control group. CONCLUSION: The stress management program helped children of alcoholics by enhancing self-esteem, providing information about alcohol, and improving emotional and problem focused coping abilities. This eventually enhanced mental health.

Malignant mixed miillerian tumor (MMMT) was one of the rare uterine sarcoma. This tumor is composed of sarcoma and carcinoma. Primary MMMT in the peritoneum is among the rarest sites for MMMT. MMMT is highly malignant and the prognosis is grave due to frequent recurrence and metastasis. In the world literature, only 22 cases with primary MMMT of the peritoneum have been reported and most of these were single report. We report one case of primary MMMT in the peritoneum with a brief review.

The eukaryotic cell is compartmentalized by a series of vesicular organelles which constitute the endocytic and exocytic transport pathways. Each vesicular compartment has distinct sets of membrane proteins, structures and functions. Despite continuous vesicular transport, each vesicular compartment maintains its structure and function by use of retention and retrieval signal for its own resident proteins. Proteins in transit along the endocytic and exocytic pathway are transported without admixing with cytoplasmic constituents by successive steps of budding from the donor vesicles, formation of intermediate transport vesicles, transport, targeting to and fusion with acceptor vesicles. Specificity and fidelity of the vesicular transport are conferred by vesicular membrane proteins and small molecular weight GTP-binding proteins of the Rab subfamily. Proteins for export are packaged into specific vesicles for their final destinations. Insertion into and retrieval from the plasma membrane of transport proteins in response to cellular stimulus are a new paradigm of cellular regulatory mechanism. Secretion of neurotransmitters, hormones and enzymes by exocytosis involves a complex set of cytosolic proteins, G-proteins, proteins on the secretory granule membrane and plasma membrane. Much progress has been recently made in identifying proteins and factors involved in the exocytosis. But the molecular interactions among identified proteins and regulatory factors are unknown and remain to be elucidated. Finally our chemiosmotic hypothesis which involves the H+ electrochemical gradient across the secretory granule membrane generated by an ATP-dependent electrogenic H(+)-ATPase as the potential driving force for fusion and release of granule contents will be discussed.

PURPOSE: The purpose of this study was to examine the effects of music therapy on anxiety of patients in emergency room. METHODS: The study was designed using a noneqivalent control group nonsynchronized design. For 20 minutes, the experimental group(22 patients) had listened to music and the control group(23 patients) had bed rest. A six-item state anxiety scale developed by Marteau and Bekker, which was based on Spielberger's State-Trait Anxiety Inventory, blood pressure and pulse rate were measured to all study participants before and after the intervention. The data was analyzed by the SPSS 12.0 program. RESULTS: 1) The experimental group's state anxiety level were significantly lower than the control group's(t=2.220, p=.032). 2) There were no significant differences in both group's diastolic(t=-.495, p=.623) and systolic blood pressure(t=831, p=.411). 3) The experimental group's pulse rate was significantly lower than the control group's(t=2.363, p=.023). CONCLUSION: Music therapy may be applied as a nursing intervention to decrease anxiety in emergency room.

BACKGROUND: The effect of arterial carbon dioxide tension (PaCO2) during ischemia and reperfusion has been a controversial issue. In this study, the effect of PaCO2 during ischemia and reperfusion was evaluated by 31P magnetic resonance spectroscopy (MRS). METHODS: Incomplete global cerebral ischemia was induced by ligation of carotid artery under lowered mean blood pressure (mean blood pressure= 40 mmHg) for 30 minutes followed by 2 hours of reperfusion. Eighteen cats were divided into 3 groups: For group 1 (n=6) (control group), animals were subjected to normocarbia (PaCO2=28~33 mmHg) during ischemia and reperfusion, for group 2 (n=6), animals were subjected to hypocarbia (PaCO2=18~23 mmHg) during ischemia and reperfusion, and for group 3 (n=6), animals were subjected to normocarbia during ischemia and hypocarbia during reperfusion. RESULTS: For group 1, the energy metabolism measured by [PCr/Pi] was recovered about 74.7 6.4%. For group 2, the energy metabolism failed to be completely recovered by 120 minutes of reperfusion (69.3 7.3%), whereas for group 3, the energy matabolism was completely recovered by 120 minutes of reperfusion (97.6 2.4%). There were statistically significant differences between group 1 and group 3 (p<0.05). The changes in pH were not significantly different among the groups. CONCLUSION: In this study, a condition of hypocarbia during reperfusion seems better for the energy metabolism after incomplete global ischemia of cats.

Effect of varying hematocrit ratio on the gastric acid production was studied in the heart-stomach preparation of the frog. When the hematocrit ratio was raised by injecting packed red blood cells obtained from the same species of frog, the acid production was increased significantly as compared to the low hematocrit group in which hematocrit ratio was lowered by injecting frog's normal saline. When a small amount of histamine was added to the medium of 25degree C, the acid production was increased in all cases, but the difference in the acid production between the high and the low hematocrit groups was abolished. However, when the temperature of the medium was lowered to 15degree C, the differences in the acid production between the two groups became significant. When a large amount of acetazolamide was added to the medium at 25degree C, the acid production was decreased significantly in both groups without showing a significant difference between the two groups. The reason(s) responsible for the increased acid production in the high hematocrit group was discussed.
