Loperamide-induced constipation reduced gastric emptying, small-intestinal and colonic motility, and these effects were prevented by Actindia chinensis(Gold Kiwi Fruit, GKF). In this study, the effects of Actindia chinensis on constipated male Sprague-Dawley rats induced by loperamide(2 mg/kg, s.c.,5 days) were investigated. Rats were randomly assigned to the normal control rats(regular diet), constipated rats(regular diet plus loperamide), constipated rats treated with 2.5% GKF(regular diet supplemented with 2.5% GKF plus loperamide), constipated rats treated with 5% GKF (regular diet supplemented with 5% GKF plus loperamide). There was less fecal excretion and lower fecal water content in loperamide-treated rats than in control rats. Oral administration of GKF blocked the decrease of fecal excretion and fecal water content in the loperamide-treated rats. Mucus production of crypt cell and mucus contents at fecal and mucosa surface were reduced by loperamide-treated rat. But colonic crypt cell contained increased mucin in the GKF treated group and mucus layer stained with alcian blue was significantly thicker in GKF treated rats compared with in loperamide-treated rats. In isolated rat ileum, loperamide produced inhibition of ileal motility. Pretreatment with methanolic extracts of GKF in isolated rat ileum prevented inhibition by loperamide. These findings indicated that the GKF was effective for alleviation of inhibition of colonic peristalsis by loperamide and that GKF might be of value in the prevention of constipation.

We investigated the immunostimulatory effects of doenjang, a famous Korean traditional food made from fermented soybean paste, on the immunohistochemical reaction in the gastrointestinal (GI) tract and immune response in mice. Male C57BL/6N mice (6 weeks-old) were divided into 4 experimental diet treatment groups and a basal diet (control) group, and fed with different diets for 4 weeks. The immunoreactive density of $CD4^+/CD8^+$ lymphocytes were strongly stained in the jejunum and colon in Group III. The immunoreactivity of universal nitric oxide synthase (uNOS) was strongly stained in the myenteric plexus in the colon of all doenjang-fedgroups (I, II and III). The colonic immunoreactive density of protein kinase C-${\alpha}$ (PKC-${\alpha}$) was strongly increased in Groups II and III, while that of stem-cell factor (c-kit) was increased in colonic mucosa of all doenjang-fedgroups (I, II and III) and especially increased in the colonic muscle layer of Group III. These morphological and immunological results indicated that the intake of doenjang could improve the mucosal immune reaction, gastrointestinal motility, blood circulation in the GI tract, and the immuneactivity of the body. These results provide experimental evidence about the health benefits of doenjang.

The battlefield environment of the Korean peninsula is rapidly changing due to the advancement of the weapon system brought by the political situation of adjacent countries and the 4th industrial revolution. The reduction of population also caused a sharp drop in the recruitment of military personnel, making it unavoidable to reform the military structure. This meaningful study is timely with recent news reports on the shortage of recruitment by 10,000 persons in the last five years. Universities are also seeing a decrease in the number of new students due to the reduced school-age population, and affiliated universities are responding to this issue with great seriousness. With a reduction in manpower, requirement-handling military units need to step up their efforts to secure competent noncommissioned officers while affiliated universities must also train capable noncommissioned officers. As a solution to the matter at hand, this study aims to suggest a method that may vitalize both the navy and the navy-affiliated universities based on the results of literature research.

Background: The aim of this study is to define the cardioprotective effects (hemodynamic, cytochemical and ultrastructural of the newly developed Histidine-Tryptophan-Ketoglutarate (HTK) cardioplegia compared to DelNido cardioplegia. Material and Method: Seventy-nine isolated rat hearts were divided into three groups on the basis of techniques of cardioplegia infusion. Twenty-eight hearts (Group 1) were flushed with cold DelNido cardioplegia with every 40 minutes for 2 hours. Twenty-seven hearts (Group 2) were flushed with cold HTK cardioplegia for once during the 2 hours. Twenty-four hearts (Group 3) were flushed with cold HTK cardioplegia with every 40 minutes for 2 hours. Heart rate, left ventricular developed pressure (LVDP), changes of + dp/dt max, coronary flow, and rate-pressure product value were measured at pre-ischemic, post-reperfusion 15 minutes, 30 minutes, and 45 minutes for hemodynamic study. Aspartate aminotransferase (AST), lactate dehydrogenase (LD), creatine kinase (CK), CK-MB, troponin-I, myoglobin, and lactate were measured at pre-ischemic and post-reperfusion 45 minutes for cytochemical parameters. Mitochondrial scores were counted in 3 cases from each group for ultrastructural assessment. Result: In hemodynamic study, there were no significant differences among group 1, group 2, and group 3. However, the decrease values of heart rate in group 2 and 3 exhibited significantly lower values than in group 1. In cytochemical study, there were no significant differences among group 1, group 2, and group 3. However, the increase values of lactate in group 2 and 3 exhibited significantly lower values than in group 1. In ultrastructural assessment, the mean myocardial mitochondria scores in group 1, group 2, and group 3 were 2.14$\pm$0.10, 1.52$\pm$0.57, and 2.10$\pm$0.16. Conclusion: HTK solution provides adequate myocardial protection with some advantages over DelNido solution in isolated rat hearts.

This study was performed to examine the cytotoxic effects of nicotine on the seminiferous tubules and Leydig cells in mice testis. A different amount of nicotine (2～15 mg/kg, for two weeks, one dose of 100 mg/kg) were administered to four-month male mice, and then the optical microscopic findings of its effect on testis of the mice are as follows: 1. The group that 2 mg/kg of nicotine was administered showed normal findings that nucleus and cytoplasm of Leydig cells are distinct, while the other group that 5 mg/kg of nicotine was given to showed nucleus and cytoplasm are swollen and thickened a little, and slightly dyed. 2. The group that 10 mg/kg of nicotine was given had irregular arrangement of spermatogenesis inside seminiferous tubules so it was impossible to distinguish phages of seminiferous tubules. It was also impossible to observe cells due to fusion of their nucleuses, and distinct cytoplasm. 3. The group that 15 mg/kg of nicotine was administered showed destruction of nucleuses and cytoplasm of spermatocytes and sperms and a fill of fibered connective tissues so that it is impossible to observe rumens of seminiferous tubules.

Moral education is essential to the military in fostering elite warriors to have clear sense of their nation and the security, while arming themselves with military spirit that strives for victory. To reach this goal, various moral education has been set forth through boot camp training, academic education, unit training, etc. depending on various subject and supporting agencies in question. Also, in order to heighten the effect of the education, various attempts to combine concert-style cultural activities with the programs are carried out. However, the ultimate goal for this moral education is to facilitate soldiers to voluntarily set their minds and will in combat, and the current education system lacks that motivation as it concentrates mostly on educating knowledges about nationality and security. Under such circumstances, various units have attempted to raise morality in creating many public and media activities within the unit, which proven to be successful. In theory, the usual definitions in the field of education such as emotion, interest, attitude, and personality can be expanded upon with public and media activities. With this in mind, we have researched on how effective this method is by conducting various public and media activities in multiple units, total of 531 soldiers, starting from June to July of 2016. As a result, these activities brought positive effects on young soldiers to build pride in their assigned units, and also increased their willingness to carry out their assignments and missions. Through this research, we drew to the conclusion that unit-level public and media activities, which was solely used for gaining trust and communicate with the general civilians, can be used to boost the soldiers moral strength and help them express the strength in action.

Objectives : We investigated the characteristics of perceived stress response and relationship between some variables of gastrointestinal symptoms(esp., dyspepsia) and subscales of perceived stress response inventory(PSRI) in patients with upper gastointestinal disorder when they perceived stress. Methods : 84 patients with upper gastrointestinal disorder(gastritis, gastric ulcer, duodenal ulcer etc.) and 94 normal controls completed the PSRI developed by Korean psychiatrists. The patient group performed the questionnaire including some variables of gastrointestinal symptoms. Results : Internal consistency was statistically significant in all subscales of PSRI. The patient group was significantly higher at total score of PSRI, general somatic symptom subscale score, specific somatic symptom score than control group. As the result of stepwise regression analysis for relationship between some variables of gastrointestinal symptoms ans subscales of PSRI, specific somatic symptom subsclae closely related with illness duration, past illness history and severity of symptom, and the lowered cognitive function & general negative thinking subscale related with the existence of emotional distress. Conclusion : Patients with upper gastrointestinal disorder showed stronger perceived stress response than control group and they experiences somatic symptoms related to autonomic nervous system and/or gastrointestinal symtoms rather than emotional, cognitive, behavioral symtoms when they perceived stress. They also responded to stress as they expeirenced specific somatic symtom when they had long illness duration, past illness history, and high severity of symptom and the existence of emotional distress could develop lowered congnitive function and general negative thinking.
