Thirty-nine healthy pigs (28-32 days old) were purchased from a commercial swine farm and housed at swine pens of the College. The animals were vaccinated intramuscularly (1 ml) with an attenuated live hog cholera virus (HCV, LOM strain) and then boostered at 5 weeks after the first vaccination. The animals were divided into 4 experimental groups: 0.05% (w/w) PowerFeel-supplemented diet (T-1, n = 10); 3% (w/w) SuperFeed-supplemented diet (T-2, n = 10); diluted PowerFeel solution (1 : 500, v/v) as drinking water (T-3, n=9); control (n=10). PowerFeel is an original form of ionized alkali mineral complex (IAMC) and SuperFeed is a commercial product of IAMC. The subpopulation of lymphocyte in blood was assayed by a flow cytometry and HCV-specific antibody was determined by an indirect immunofluorescence assay. In IMAC-treated groups, the proportions of subpopulation expressing MHC-class II, CD2+, CD4+, CD8+, and surface IgM+ B lymphocytes were significantly decreased at 5-weeks after the first vaccination. Significant decreases were also observed in the proportions of MHC-class II, CD2+ and CD8+ lymphocyte at 3-weeks after the booster injection. The humoral immune responses in T-1 and T-2 groups were greater than those in T-3 or control group. These results suggest that IAMC-supplemented diets may have an HCV-specific immunostimulatory effect in pigs.

Eosinophilic granuloma of bone, characteristically a disease of children and young adults, is the most benign variant of histiocytosis X. This benign bone destructive lesion is characterized by the presence of a histiocytic and eosinophilic leukocyte infiltrate of unknown origin. It was described as a new distinct entity by Jaffe and Lichtenstein(1940). we reviewed the ll patients with eosinophilic grnuloma of bone from January 1980 to December 1985. The average length of follow-up was 20 months, with a range of 10 to 38 months. The results were as follows. l. Incidence was 2.24% of primary bone tumor. 2. Male patient was more predominent. 3. Age of onset was between 2 and 16 years old. 4. Predilection sites were spine, skull, pelvis and femur in order. 5. Solitary lesion was more comon(63.5%). 6. Onset of multiple lesions was earlier age. 7. There was on recurrence of lesions.

This statistical analysis of 4,709 legal autopsies performed in Korea in 2012 was conducted to obtain primary data about and related variables. The analysis revealed the following: 1. Of the total number of deaths, men accounted for and women, 26.8%. Evidently, the number of deaths among men was more than twice that among women. 2. With respect to mode of death, 54.8% were recorded as unnatural deaths, 39.2% were natural deaths, and 6.0% had unknown causes. Of the 2,581 unnatural deaths, 44.8% were accidental deaths; 27.2%, suicidal; 17.5%, homicidal; and 10.3%, undetermined. 3. Of the total number of unnatural deaths, 43.0% were trauma-related deaths, for which falling down was the leading cause, accounting for 33.5% cases. Asphyxiation was accounted for 17.2%, among which the predominant cause was hanging (55.3%). Moreover, 12.5% of deaths were due to drowning; 11.5%, poisoning; 11.2%, thermal injuries; 2.7%, complications in medical procedures; and 0.3%, electrocution, starvation, or neglect. 4. Among 1,847 natural deaths, heart diseases accounted for 50.2% and vascular diseases accounted for 16.7%. 5. There were 207 cases of deaths among children under the age of 10, of which 94 were unnatural and 49 were homicidal deaths. Of all cases, 9.2% had an unknown cause of death, and of these 67.6%, were putrefied or skeletonized bodies.

PURPOSE: Proliferation of bile duct-like structures and fibrosis is a hepatic cellular reaction observed in most forms of human liver disease and in a variety of experimental conditions associated with liver injury. The aim of this study was to investigate the activation of Ito cells and bile duct proliferation in the rat after common bile duct ligation (CBDL). METHODS: Hepatic morphological abnormalities were examined in rats whose bile ducts had been irreversibly ligated for 15, 21, 24 and 28 days. The liver was examined by immunohistochemical staining for alpha-smooth muscle actin, the known marker of activated Ito cells, and light and electron microscopes. RESULTS: After CBDL, the bile canalicular proliferation and interstitial fibrosis were gradually increased in the periportal areas extended to hepatic sinusoids. Ito cells positive for alpha-smooth muscle actin were frequently observed in the periductular space and in perisinusoidal space of Disse. Ito cells and myofibroblasts were gradually increased in the interstitial fibrosis until the 28th day after CBDL. Ito cells and myofibroblasts had microfilaments with dense body at the periphery of the cell. CONCLUSIONS: Our results suggest that Ito cells may be fibroblastic or myogenic. It has also been postulated that during the development of hepatic fibrosis, Ito cells become myofibroblasts or fibroblast like cells.

BACKGROUND: Beta-adrenergic receptor Kinase 1(betaARK1) is a serine/threonine kinase attached, which inhibits the coupling of beta-adrenergic receptor with G-protein. Myocardial betaARK1 level is usually elevated in heart failure and hypertrophy, but it is not known whether the circulating betaARK1 level is related with the degree of cardiac hypertrophy. This study was performed to evaluate the association of the betaARK1 level in circulating mononuclear leukocytes(MNL) in untreated hypertension with left ventricular mass in hypertensive patients. Method: Nineteen non-treated hypertensive patients were included for this study. High blood pressure was confirmed when systolic BP is over 150 mmHg or diastoli BP is over 95 mmHg. Echocardiography was performed to evaluate the degree of hypertrophy by measuring the left ventricular mass index(LVMI) and relative wall thickness(RWT), and test the LV function by measuring the ejection fraction(EF) according to ASE guideline. At the same time, blood was collected from each patient and MNL were isolated by gradient centrifuge with Ficoll-400. Total RNA was purified from MNL and semi-quantitative RT-PCR was performed. After reverse transcription, PCR was done with primers for human betaARK1 and GAPDH as external control. betaARK1 levels were expressed by ratio to GAPDH level and estimated the relations with clinical and Echocardiographic parameters. Result: We studied confirmed 19 hypertensive patients(10 men and 9 women, mean age of 50.6 years). Echocardiographically measured indices(mean+/-SD) were as follows; LVMI(137.3+/-30.6g/m2), PWT(0.53+/-0.09) and EF(54.6+/-8.5%). Ratio of betaARK1 levels to GAPDH was from 0.10 to 0.96 (0.62+/-0.25). betaARK1 levels were correlated with LVMI(correlation coefficient: r=.502, p=.029) and RWT(r=.627, p=.004). But Systolic BP(r=0.009, p=.93), diastolic BP(r=.07, p=.85) or EF(r=.045, p=.84) were not related to level of betaARK1. CONCLUSIONS: The betaARK1 level of circulating MNL was correlated well with the degree of the cardiac hypertrophy estimated by LVMI and RWT. This data suggests that activation of sympatho-adrenal system would exert a major role in developing cardiac hypertrophy and we can expect the decreased responsiveness to catecholamine in the heart of hypertensive patients. betaARK1 in circulating MNL might be used as a predictor or marker for LV hypertrophy in hypertensive patients.

A night blood survey was carried out among inhabitants aged over 1 year from the fifteen villages throughout Cheju-Do (Quelpart Island). Blood films from 2,139 persons were examined and 183(8.6 percent) showed microfilariae, the incidences varying according to geographical sources are from 0.8 to 19.5 per cent. All the microfilariae found in this survey were of the nocturnal periodic Brugia malayi. The microfilarial density was 1.9 per cent of blood. The age and sex distributions of microfilaria rate in Cheju-Do were not distinctly different. On the other hand, the intradermal test using Dirofilaria antigen (FPT antigen) and clinical survey of filariasis were also undertaken in same areas of microfilaria survey. Out of 2,449 inhabitants examined 1,434(58.6 percent) persons showed positive reaction of skin test, 503(20.5 percent) persons have clinical manifestations and 112 (4.6 percent) persons showed elephantiasis . It is assumed that Aedes togoi may be the most probable vector of B. malayi in the areas of Cheju-Do.

OBJECTIVES: Shift work is a stressful situation. It is important to know the factors associated with the ability to adapt to a shift work schedule. The aim of the present study was to investigate the association between sleep, as well as personality variables, and the resilience of shift work nurses. METHOD: Self-report questionnaires were administered to 95 nurses who worked in one national university hospital. Connor-Davidson resilience scale, hospital anxiety and depression scale, morningness-eveningness scale, Pittsburgh sleep quality index, other sleep-related questionnaires, and Korean defense style questionnaires were used. RESULTS: Age, shift work duration, off-day oversleep, depression, anxiety, adaptive defense style, and self-suppressive defense style were significantly associated with resilience (p < 0.05). Multiple regression analysis showed that age (beta = 0.34, p < 0.05), depression (beta = -0.25, p < 0.05), adaptive defense style (beta = 0.45, p < 0.001), and self-suppressive defense style (beta = -0.19, p < 0.05) significantly predicted the resilience of shift work nurses. Concerning individual defense mechanisms, resignation (beta = -0.20, p < 0.05), sublimation (beta = 0.19, p < 0.05), omnipotence (beta = 0.19, p < 0.05), and humor (beta = 0.20, p < 0.05) significantly predicted the resiliency. CONCLUSION: The findings indicate that a specific defense style and other mechanisms were associated with the resilience of shift work nurses. A future prospective study with more participants could further clarify the relationship between sleep-related variables, as well as personality factors, and resilience of shift work nurses.

Head trauma is the most frequent cause of morbidity and death in abused children. The shaken impact syndrome results from both types of injury-impact and severe acceleration-deceleration effects associated with impact causing shearing forces on the bridging veins and parechyma. To make the diagnosis of shaken impact syndrome, the physician should be suspicious of every child under 1 year of age with non-accidental brain injury and altered consciousness. Certain clinical features such as retinal hemorrhage , complex, depressed, or diastatic fractures, and associated findings such as metaphyseal fracture and failure to thrive make the diagnosis of abuse more likely. Yet in the absence of these findings, the diagnosis of abuse rests upon discrepancies between the history given and the injury incurred. We experienced a case of shaken impact syndrome in a 13 month-old female who had subdural hemorrhage, fractures of skull and rib, and encephalomalacia, so we report and review the related literatures.
