A congenital salivary gland tumor, sialoblastoma, is extremely rare. A sialoblastoma of the parotid gland, occurring in a 28-week old fetus, is described. The histologic, immunohistochemical, and ultrastructural features of this tumor were studied. The tumor was characterized by solid nests or sheets of tumor cells intermingled with ductal structures lined by a columnar cells. Some of the tumor cells showed squamous differentiation. Immunohistochemically, these epidermoid cells reacted positively with anti-cytokeratin. But anti-S-100, anti- vimentin, anti-smooth muscle actin, anti-GFAP positive cells were not found. The ultrastructure was characterized by primitive epithelial cells. Although various names have been proposed, we favored the term "sialoblastoma". The histogenesis of this tumor is also discussed.

Various techniques for treatment of large bone defects have been reported, instead of using autogenous bone graft. The author have applied and explored for bone repair with polyglactin 910 mesh and fresh fascia late. Full thickness 8x8mm bone defects were made on the frontoparietal bone of rabbits and group 1 defect was covered with polyglactin 910 and group 2 defects with fresh fascia late, but group 3 and 4 were not covered. However the periosteum was left on group 4 but it was not left on group 3. Samples were taken from the operation site for clinical and histological examinations on 2, 4, 8 and 12 weeks after operation, repetitively. The results were as follows ; 1. On the group 1, where ployglactin 910 mesh had been placed, the defects taken in 2, 4 ,8, 12 weeks after operation disclosed osseous regeneration with newly formed bone but the thickness was much less than the original bone. 2. On the group 2, where fresh fascia rata had been placed, the defects taken in 2, 4, 8, 12 weeks after operation disclosed same pattern of group 1. 3. On the group 3 and 4, where membrane had not been placed, the majority of the defects consisted of connective tissue and muscles. 4. On the group 1, resorption of polyglactin 910 mesh was completed after 4 weeks, but on the group 2, the fascial rata still remained intact.

PURPOSE: This study was done to examine the effects of foot massage as a nursing intervention on preoperative anxiety, depression and sleep satisfaction in patients with breast surgery. METHOD: Research design was a nonequivalent control group non-synchronized design. Forty-one patients were assigned to the control group (21) and the experimental group (20). The patients answered a questionnaire containing measures of anxiety, depression and sleep satisfaction before and after the intervention. The collected data were analyzed by means of descriptive statistics, Cronbach's alpha, Chi-square test, and t-test using the SPSS WIN 11.0 program. RESULT: Anxiety and depression for the experimental group were significantly lower than those for the control group(t=2.556, p=0.008, t=2.932, p=0.006). Sleep pattern of the experimental group was significantly higher than that of the control group (t=2.313, p=0.013). CONCLUSION: Judging from these results, it is suggested that foot massage might have beneficial effects on reducing preoperative anxiety, depression, and increasing sleep satisfaction.

Pulmonary artery sling is an uncommon and potentially lethal vascular anomaly that can produce airway obstruction. Despite the availibility of a corrective operation, the mortality rate remains very high due to the high incidence of associated obstructive anomalies of the tracheobronchial tree. We experienced a 70-day-old male infant who was admitted to our unit because of sudden dyspnea, cyanosis, coarse expiratory wheezing and inspiratory stridor. At first, he was treated with bronchodilator and steroid under the impression of infantile asthma, but the symptoms went on without interval change. We performed magnetic resonance imaging study followed esophagography and two dimensional echocardiography. Finally he was diagnosed as a vascular sling. We report this with a brief review and related literatures.

BACKGROUNDS: This study was investigated for assessing of the sedative dose of midazolam and its influence on neonatal Apgar score that intravenously injected immediately before operation during epidural anesthesia for cesarean section. METHODS: Midazolam, 1 mg, was given into a freely running IV line every 30s 2 min after 2 mg of midazolam was initiately injected. Ten seconds prior to each injection patients were asked to open the eye. No response, as determined by the anesthesiologists, to three promptly repeated and increasingly louder commands was considered the end-point for the study and no further midazolam was given. RESULTS: The sedative dose of midazolam in our study was 3.3 1.1 mg and interindividual variation (range: 2~7 mg) were wide. Respiratory depression was occurred in one of pregnant women with midazolam. All of the Apgar scores of the newborn infants at 1 and 5 min in both groups were higher than seven. CONCLUSIONS: When the intravenous injection of midazolam for sedation immediately before operation is required in pregnant women during epidural anesthesia for cesarean section, we would like to suggest that one should initiately administer the small dose and then inject the incremental dose with careful observation of the respiratory status.

The birth of conjoined twins remains an extremely rare event. Most of such twins are stillborn and one third of the live births die within first day of life. In Korea, there are only three reports on the anesthesia for separation of different kinds of conjoined twins. In view of anesthesia for separation of such twins prematurity, low birth weight, and anomalous shared organ play the major role on the perioperative morbidity and mortality. Such anesthesia therefore is one of the exceedingly complex fields among the pediatric anesthesia and require mobilization of all possible methods and monitoring devices used for pediatric anesthesia. We performed careful preoperative evaluation of extent of joining, discussion and rehearsal of separation procedure between separation team, and anesthetic care such as all possible monitoring, preservation of body temperature, appropriate fluid therapy, awake intubation, avoid neuromuscular blockers, and thorough separation of duty. The separated twins showed normal weight gain postoperatively and discharged postoperative 31th day without any complications.

The aspergillus tracheobronchitis is distinctive manifestation of invasive aspergillosis, in which infection is limited completely or predominantly to the tracheobronchial tree. It accounts for about 7 to 10 percent of cases of invasive disease. Grossly, such disease may take the mucosal exudate and obstruct partially the airway lumen or completely the occlusive mucous/fungus plugs. Microscopically, the superficial portion of the airway wall is acutely inflamed and contain fungal hyphae. However, infection is often limited to the mucosa. We report a case of aspergillus tracheobrochits in a 54 year-old man who presented cough, progressive dyspnea with wheezing, and mucus plug. Bronchoscopy showed mucosal exudate and plug.Bronchoscopic biopsy showed aspergillus hyphae and inflammation in the mucosa. He was successfully treated with itraconazole.

Rehmannia glutinosa is a perennial medicinal plant belonging to the family Scrophulariaceae with more than 300 species known in the world, especially in temperate regions. Its roots have been used widely in Korea for medicinal purposes. However, it is commonly infected by various pathogens during storage, causing great damage to the roots, and impedes the intensive farming of the crop. Therefore, an attempt has been made to isolate and screen a resistance gene against the pathogen Fusarium oxysporum using differential display. We treated salicylic acid (SA), and isolated a resistance gene that responds to SA. As a result, we found that SA was involved in plant defense mechanism in pathogenicity tests with SA treated and non-treted plants, and we isolated a partial PR-la gene through differential display polymerase chain reaction (DD-PCR) method.
