A case of mucous gland adenoma arising from the main bronchus of the middle lobe of the right lung is reported, with review of related literatures. The patient, a 12 year-old Korean male, was admitted to Pusan National University Hospital with complaints of progressive coughing and dyspnea. Roentgenographic studies revealed a well defined mass involving the right middle lobe of the lung. With the impression of benign tumor, right middle lobectomy was performed. The gross specimen revealed a polypoid mass involving the main bronchus, measuring 4.5x 3.7 x 2.5cm. The cut surface of the mass revealed yellow-gray myxoid tissue. Histologically, the mass consisted of glandular structures filled with mucus, which proved to be acid one on histochemical study. The glandular lining was made up of a single layer of berign mucous cells, many of them being flattened.

The changes in the size of human oviduct and ovary after immersion in formalin (4%, 10%) were investigated. The results were as follows : 1. After fixation, the length of oviduct was significantly reduced to 93%, but the cross sectional area of oviduct was significantly increased. The length of oviduct showed no significant difference between 4% and 10% formalin. The length of ovarian ligament was also significantly reduced to 84% after fixation. 2. After fixation, the volume of oviduct was increased significantly and showed a difference between the two fixatives. The volume of oviduct in 4% formalin has increased to 107%, as compared to 103% increase in 10% formalin. 3. After fixation, the volume of ovary was increased significantly and showed a difference between the two fixatives. The volume of ovary in 4% formalin has increased to 109%, as compared to 103% increase in 10% formalin.

Various anatomical defects have been described in the surviving co-twin who had stillborn, macerated monozygotic co-twin with disseminated intravascular coagulation. The suggested mechanism was the transfer of emboli or thromboplastic materials of dead fetus to co-twin through placental vascular anastomoses. Multicystic encephalomalacia is the condition defined anatomically by the presence of multiple cavities in the great part of both cerebral hemispheres. The most common pathogenesis is circulatory disturbance caused by neonatal asphyxia during the perinatal period. We experienced two cases of monozygotic twin with deceased co-twin at 26 weeks, 33 weeks of gestation and confirmed the diffuse multicystic encephalomalacia by cranial ultrasonography and MRI in a surviving co-twin. Only one patient has been followed who showed spastic cerebral palsy and severe mental retardation. We report two cases of multicystic encephalomalacia in a surviring co-twin with a intrauterine fetal death and its related literatures.

PURPOSE: This study investigates nurses' organizational commitment, internal marketing, and occupational satisfaction depending on their age, martial status, clinical experience and income. METHODS: The subjects of this study were 350 nurses from six hospitals in Jeolla-do. The t-tests were used to analyze the differences in internal marketing, occupational satisfaction, and organizational commitment depending on their age, marital status, career, and income. The relationships among internal marketing, occupational satisfaction, and organizational commitment were analyzed by the path analysis. RESULTS: The results of this study showed that organizational commitment was correlated with age, clinical experiences, and income, but not significantly associated with martial status. Education and training policy, benefit system, and fairness of the internal marketing were influencing factors on occupational satisfaction. These factors were correlated with organizational commitment through occupational satisfaction. CONCLUSION: This study addressed the relationships among nurses' internal marketing, occupational satisfaction, and organizational commitment. Based on the results, it is suggested that hospital organizations introduce more diverse incentive policies to enhance nurses' occupational satisfaction and organizational commitment.

PURPOSE: The purpose of this study was to understand sexual behavior of college students and to provide basic resources for a counseling program and sexual health education program by identifying general tendency of sexual behavior and analyzing demographic and environmental variables that affect sexual behaviors. METHODS: To identify sexual behaviors according to demographic and environmental variables of college students, t-test and one way ANOVA were done using the SPSS/WIN 18.0 program. Multiple regression analysis was done to identify the effects of demographic and environmental variables upon sexual behaviors. RESULTS: As to sexual behaviors, male students, upper grade students, engineering division students, students with higher economic status, students with opposite gender friends, and students with experience in receiving obscene materials were more vulnerable to sexual behavior. As to demographic and environmental variables, they explained 25% of variances in 'sexual behavior'. CONCLUSION: The results of this study indicate that development of mental health nursing strategies for university students are required for effective sexual counseling on sound relationships and sexual health matters.

A rare case in the pattern of the origin of the celiac artery was observed in the cadaver of a 64 year old Korean male and the results are summarized as follows. The superior mesenteric artery originated from the abdominal aorta at the level of the intervertebral dusk between first and second lumbar vertebra. At a point 4cm from the origin of the superior mesenteric arterr, a common trunk appeared and ran 1cm and then divided into the common hepatic artery and the splenic artery. The common hepatic artery divided into the right gastric artery and the proper hepatic artery at a point 4.5cm after the bifurcation. A common trunk formed by the left inferior phrenic artery and the lefts gastric artery arose from the abdominal aorta about 0.8cm about the origin of the celiacomesenteric trunk.

It remains a problem that successful revascularization and reperfusion after ischemia are associated with high systemic complication rates and severe local tissue injuries. With prolonged ischemia, there is damage to tissue from anoxia, but further injury may occur after reperfusion. The activation of leukocytes and endothelial cells during reperfusion causes neutrophil adhesion in capillaries, resulting in plugging and further ischemia, Alternativety, neutrophil adhesion to endothelium leads to the migration of neutrophil with local edema formation, hemorrhage and thrombosis. Some chemotactic and activating factors are needed to propel neutrophils to the site of local inflammation. The chief cytikines that induce a pro-adhesive state in endothelium are tumor necrosis factor-alpha(TNF-alpha), interleukin-1 beta(IL-1 beta) and endotoxin or lipopolysaccharide(LPS). Similarly, TNF-alpha,and to a lesser extent interleukin-8(IL-8), is the important stimulus that acts on neutrophils and other leukocytes to alter their adhesion. The purpose of this study was to evaluate the pathogenetic role of IL-8 after perfusion with CDl8 monoclonal antibody(CDl8 mAb), the blocking antibody of neutrophil adherence, on reperfusion injury in rat epigastric island skin flap. A 6 X 3 cm-sized island skin flap was made on the abdomen. The epigastric pedicle was occluded for six hours with ambient temperature. Fifteen minutes before reperfusion, the flap was perfused with saline and CDl8 mAb(1 mg/kg). For evaluation of IL-8 levels, tissue fluid and serum were obtained at 4, 8, 12 and 24 hours after reperfusion. IL-8 concentrations of the CDl8 mAb group in the tissue fluid were significantly decreased at 8, 12 and 24 hours compared to the control group(P > 0.01), but the difference between the two groups was not significant at 4 hours after reperfusion IL-8 concentrations of the CDl8 mAb group in the serum were significantly decreased over time compared to the control group(P > 0.05, p > 0.01). Form the above results, we concluded that blocking neutrophil adherence using CD18 mAb within the peak level of IL-8 at 4 hours after reperfusion may be a better method of reducing reperfusion injury to the island skin flap.
