1.Studies on transaminase reactions in some parasitic helminths.
The Korean Journal of Parasitology 1966;4(2):7-13
By an application of Sigma-Frankel methods, two transaminase systems, glutamic-pyruvic transaminase and glutamic-oxaloacetic transaminase, were found to operate at a mesurable rate in 2 species of nematodes(Ascaris lumbricoides and Ascaridia galli), 5 species of trematodes (Clonorchis sinensis, Fasciola hepatica, Eurytrema pancreaticum, Paramphistomum cervi and Paragonimus westermani) and 5 kinds of cestodes (Diphyllobothrium mansoni, Dipylidium caninum, Taenia pisiformis, Cysticercus cellulosae and Cysticercus pisiformis). A comparison was made of the transamination reactions in nematodes and those of trematodes and cestodes. And the significance of transaminase in these parasites is discussed in relation to protein synthesis and its utilization.

BACKGROUND: Osteoporosis is developed by progressive decrease of bone rnass from decreased collagen content of bone. Accurate measurement of bone collagen is necessary for the diagnosis of osteoporosis and it is possible by bone biopsy, however bone biopsy is not easy in clinical practice. Skin collagen is consist with type I collagen which is same type of bone collagen and progressive decrease of bone collagen is reflected by decrease of skin collagen. Since skin thickness reflect skin collagen amount, skin thickness measurement may be a useful method for the evaluation of osteoporosis. So ultrasonic skin thickness measurement was developed for the evaluation of osteoporosis. METHODS: A randomly selected 200 women aged fram 30 to 71 years old were asked to have their skin thickness measured as well as lumbar vertebral DXA(Norland, USA) bone densitometry. Except for the two women who failed to complete the study, 45(22.7%) of these women were diagnosed as normal, 74(37.4%) were osteopenic and 79(39.9%) were diagnosed as osteoporosis patients using the WHO criteria. Skin thickness was measured using 20MHz Osteoson DCIII (Minhorst, Germany) at the medial side of the upper arm. A minimal of Two scans were measured and the mean value was cakulated automatically. RESULTS: The correlation coefficient of skin thickness and age was -0.121(ns), DXA BMD(bone mineral density) and age was -0.420(P<0.01), skin thickness and DXA BMD L2-L4 was 0.181(P<0.05). Skin thickness was significantly correlated with body weight(correlation coefficient 0.254, P<0.01) and BMI(correlation coefficient 0.195, P<0.01). Furthermore, the mean and standard deviation of skin thickness in normal BMD group was 0.94+-0.021mm, osteopenic group was 0.92+-0.006mm, and osteoporotic group was 0.89+-0.018mm. There was statistically significant difference in the mean values of skin thickness between the three groups even adjusted with age and BMI(P<0.05). The mean and standard deviation of skin tbickness of healthy 20-40 year old women was 1.11+-0,023mm and their mean and standard deviation of L2-L4 mean BMD was 1.17+-0.145mg/cm2. The diagnostic predictability of skin thickness less than 1mm as the risk of osteoporosis(BMD T score less than -1.0) was evaluated. The sensitivity and the specificity of skin thickness less than 1mm being osteoporotic were 78,2% and 57.8% respectively. The positive and negative predictive value of the skin thickness less than 1mm being osteoporotic were 82.2% and 36.5% respectively. CONCLUSION: This study indicate that the skin thickaess measured with the ultrasound method show good correlatian with the bone density measured with conventional DXA at the lumbar vertebra and the skin thickness less than 1mm on the medial side of the opper arm is relatively sensitive in diagnosing osteoporosis risk in Korean women. The authors suggested that a large randomized control study to define the relationship between the skin thickness and the other determinants of bone turnover in the near future.

Purpose:
: This study aimed to identify the moderating and mediating effects of resilience on the relationship between role conflict and job satisfaction among nurses working in a comprehensive nursing care service ward.
Methods:
: Participants were 130 comprehensive nursing care service ward nurses from four hospitals. Data were collected using structured questionnaires and analyzed by t-test, ANOVA, Scheffé test, Pearson correlation coefficients, and hierarchical multiple regression analysis, using SPSS 25.0. The mediating effect of resilience on the relationship between role conflict and job satisfaction was analyzed using multiple regression analysis according to Baron and Kenny’s procedure.
Results:
: Statistically significant negative correlations were found between role conflict and resilience (r=-.25, p<.007) and between role conflict and job satisfaction (r=-.38, p<.001). A significant positive correlation was found between resilience and job satisfaction (r=.54, p<.001). A partial mediating effect of resilience was found between role conflict and job satisfaction (Z=-2.53, p=.012) but no moderating effect was found.
Conclusion
: To improve the job satisfaction of comprehensive nursing care service ward nurses, interventions for alleviating role conflict and improving resilience as well as evaluations of the two variables are necessary.

Community-based health management policies are needed considering societal aging. We aimed to develop a transitional care model (TCM) program for patients with pneumonia, asthma, and chronic obstructive pulmonary disease. First, we conducted in-depth interviews with patients who were hospitalized, released, and readmitted for those three conditions to identify issues with the current hospitalization/discharge system and post-discharge processes. Next, we developed a new TCM program suited to the realities of the current medical environment. Interviews revealed problems including inadequate awareness of disease and health management; insufficient information exchange between patients, caregivers, and primary medical institutions; and absence/low usage of community-based care services. The investigation applying the new TCM program to patients and following up on readmission rates and life satisfaction after discharge is ongoing. Reviewing these results and conducting further studies in the future will allow improvements to the model.

PURPOSE: Hepatic atrophy has been recognized as a complication of hepatic and biliary disease but we have often found it in follow up CT after transcatheter arterial embolization {TACE). The purpose of this study is to evaluate the characteristics of hepatic atrophy after TACE. MATERIAL AND METHODS: Of 53 patients who had TACE, We evaluated the relationship between the incidence of hepatic atrophy and the number of TACE, and also evaluated the average number of TACE in patients with hepatic atrophy. Of 20 patients who had received more than average number of TACE for development of hepatic atrophy (2 times with portal vein obstruction, 2.7 times without portal vein obstruction in this study), we evaluated the relationship between the tipiodol uptake pattern of tumor and the incidence of hepatic atrophy. RESULTS: There were 8 cases of hepatic atrophy (3 with portal vein obstruction, 5 without portal vein obstruction), average number for development of hepatic atrophy were 2.5 times. As the number of TACE were increased, the incidence of hepatic atrophy were also increased. Of 20 patients who received more than average number of TACE for development of hepatic atrophy, we noted 6 cases of hepatic atrophy in 11 patients with dense homogenous lipiodol uptake pattern of tumor and noted only 1 case of hepatic atrophy in 9 patient with inhomogenous lipiodol uptake pattern. CONCLUSION: Hepatic atrophy was one of the CT findings after TACE even without portal vein obstruction. Average number of TACE was 2.5 times and risk factors for development of hepatic atrophy were portal vein obstruction, increased number of TACE, and dense homogenous lipiodol uptake pattern of tumor.

The adult trematodes, Fasciola hepatica, Eurytrema pancreaticum and Paramphistomum cervi, employed in this experiment were obtained from the cattle slaughtered at the local abbatoir. The worms selected and washed several times in normal sterilized saline solution. Each about ten of intact F. hepatica, fourty of E. pancreaticum, and twenty of P. cervi were incubated in 50 cc volume of special incubation flasks with incubation medium consisting of 10 cc. of Krebs-Ringer phosphate buffer(pH 7.4) The incubation medium was added C(14)-1-acetate and non-radioactive carrier Na-acetate so as to contain acetate concentration of 50 mg per cent . The worms were allowed to incubate for 5 hours in the Dubnoff metabolic shaking incubator at 38 C. After incubation period, respiratory CO(2) samples from central well of incubation flask were analysed for total CO(2) production rate and their specific activity of respiratory CO(2). The lactate and pyruvate appearance rates were determined by analyzing the lactate and pyruvate concentration in a medium after incubation. The glycogen samples isolated from worms were analyzed for the tissue concentration and their radioactivities in order to determine the turnover rate of glycogen pool. Radioactivities of these series of experiments were counted by an endwindow Geiger-Muller counter as an infinitely thin samples. The quantitative analysis of C(14)-acetate utilized by F. hepatica, E. pancreaticum and P. cervi were compared and discussed in this report. According to these data of the experiment, it is suggested that the fatty acid such as acetate may play a part of their oxidative process into the respiratory CO2 and the synthetic process into glycogen in the above species of trematodes.
