OBJECTIVES: Ginseng has a long history of being used in insomnia treatment and there is some evidence from animal studies of its sleep-enhancing property. From this, it can be assumed that ginseng has sleep-promoting effect in humans. The purpose of this study was to investigate the effect of Korean red ginseng on change of sleep architecture in humans. METHODS: A total of 20 healthy young males with regular sleep and wake habits and without any psychiatric nor cognitive problems were selected based on review of sleep questionnaires and sleep diaries they completed followed by an interview with a board-certified psychiatrist. The subjects were randomly assigned to red ginseng or placebo for 2 weeks of trial. The total daily dose of ginseng was 4,500 mg. The polysomnographic recordings were made at baseline and at 2 weeks after. The effects of red ginseng and placebo on sleep were assessed by comparing the changes in polysomnographic variables between the two groups. RESULTS: A total of 15 subjects, 8 from red ginseng group and 7 from placebo group, were included to undergo polysomnographic procedures. The red ginseng group showed tendencies to increase stage 3 sleep (p=0.087) and to decrease stage 2 sleep (p=0.071) from the baseline compared with the placebo group. CONCLUSION: Korean red ginseng tends to increase deep sleep and decrease shallow sleep. Our result is in line, at least in part, with previous findings that Korean red ginseng increased total and NREM sleep in rats. Further studies with higher ginseng dosage, larger sample size and longer trial duration should be conducted to confirm the sleep stabilizing and balancing effects of Korean red ginseng.

5.The Effect of Dongchimi Juice Containing Kimchi Lactobacillus on the Oral Health of Patients at a Long-Term Care Hospital: Comparison with Chlorhexidine Solution.
Journal of Korean Academy of Nursing 2017;47(4):540-550
PURPOSE: The aim of this study was to identify the effect of Dongchimi juice containing kimchi Lactobacillus as an oral hygiene agent and to compare it with that of chlorhexidine solution (0.12% dilution). METHODS: This study employed a pretest-posttest experimental design in which a single group of patients was exposed to two different treatments over a period of time. The study included 32 patients hospitalized at a long-term care hospital in Korea. Data were collected between August 12, 2016 and September 28, 2016. The patients first used chlorhexidine solution as an oral care agent for 1 week. After an interval of 2 weeks, they used Dongchimi juice for 1 week. Each agent was applied 2 times a day depending on the protocol. The oral status of the patients was measured using Beck's Oral Exam Guide (OEG) scores. The number of pathogens in the oral cavity was counted by culture, and the patients' subjective satisfaction score for each oral agent was measured using a visual analogue scale. T-test and Mann-Whitney test were performed to identify significant differences between Dongchimi juice and chlorhexidine solution by using PASW Statistics for Windows, Version 18.0 (SPSS Inc., Chicago, IL, USA). RESULTS: The OEG score was not statistically different with the use of chlorhexidine solution and Dongchimi juice. However, decreasing number of pathogens and the subjective satisfaction score were higher with Dongchimi juice than with the chlorhexidine solution. CONCLUSION: These findings support the use of Dongchimi juice containing kimchi Lactobacillus as an oral hygiene agent for Korean patients.

The expression of c-fos and c-jun in the brain of the rat after capsaicin treatment was investigated by in situ hybridization, dot blot hybridization and immunocytochemical methods. Adult male Sprague-Dawley rats[200g] were used for this study. The first set of rats received a single subcutaneous injection of capsaicin[50mg/Kg] dissolved in 10% Tween-80 and 10% ethanol in saline. The rats were decapitated 1, 3, 5, 10, 24, 72 hours and 1 week after capsaicin treatment. The control set of rats were treated with saline instead of capsaicin. In situ hybridization and dot blot hybridization were carried out. O1igonucleotide probe complimentary to c-fos mRNA sequences were used for this study and labeling of oligonucleotides was accomplished using the DNA tailing kit. The expression of c-fos mRNA on the nucleus of neurons in in situ hybridization was observed throughout the brain, and was especially abundant in the olfactory cortex, nucleus of diagonal band of Broca, habenular nuclei, periaqueductal gray, parabrachial nucleus, entopeduncular nucleus, ventral posterolateral nucleus of the thalamus and cerebellum. Compared to the control rats, c-fos mRNA were increased 24 hours after capsaicin injection and gradually decreased after 72 hours, returning to the normal control level 1 week after capsaicin injection. c-fos mRNA was detected only 1 week after capsaicin injection in the various areas of the brain. The fos protein-like immunoreactivity was initially somewhat decreased at 24 hours, but increased at 72 hours and reactions was maximally observed at 1 week after capsaicin treatment. But Jun protein immunoreactivity was not increased, on the contrary, it was even decreased both in numbers of reactive cells and immunoreactivity 1 week after capsaicin injection. From the above results, c-fos gene expression was pronounced in the nucleus concerned with pain, olfaction and taste such as VPL nucleus of the thalamus, olfactory cortex and parabrachial nucleus, in the limbic system concerned with stress and emotion such as nucleus of diagonal band of Broca, periaqueductal gray and habenular nucleus, in the structure concerned with somatic motor function such as entopeduncular nucleus and cerebellum. Also, the c-fos gene was activated by the capsaicin early in the course of effects, then the fos protein increased as a results of c-fos activation. On the other hand, c-jun did not respond to capsaicin treatment early in the course, but Jun protein decreased late in the course of capsaicin effects.

Animal models for human chronic pain syndromes were developed and widely used for pain research. One of thsese neuropathic pain model by Kim and Chung[1992] has many advantages for operation and pain elicitation. We have examined the c-fos protein, substance P, CGRP immunoreactivity in dorsal root ganglia and dorsal horn in this neuropathic model. About 50 Sprague-Dawley rats were used for this study. L5 and L6 spinal nerve were ligated tightly to produce neuropathic pain model. After 2, 4, 8, 16, 24 hours and 1 week of surgery, rats were anesthesized and sacrificed by perfusion through the left ventricle with saline followed by 0.1M phosphate buffer[pH 7.4] containing 3% paraformaldehyde, 3% glutaraldehyde, and 0.1% picric acid. After confirmation of the roots transected by the surgery, the L5 and L6 dorsal root ganglion and spinal cord were removed and processed for immunohistochemistry. All tissue sections were immunohistochemically stained for substance P, CGRP and c-fos by using the peroxidase-antiperoxidase[PAP] method. Count the number of immunostained substance P and CGRP dorsal root ganglion cells and c-fos immunoreactive dorsal horn cells and analyzed statistically with Mann-Whitney U test. The results are as follows. 1. The number of c-fos protein immunoreactive neurons in the superficial layer of dorsal horn were increased markedly at 2 hours after operation, gradually decreased to normal level 1 week after operation. 2. The number of c-fos protein immunoreactive neurons in the deep layer of dorsal horn were gradually increased to the peak 24 hours after operation, decreased to normal level 1 week after operation. 3. The number of substance P and CGRP immunoreactive L5 and L6 dorsal root ganglion neurons were decreased markedly at 1 week after pain model operation. In conclusion, after neuropathic pain model operation, c-fos protein were immediately expressed in the superficial layer of spinal dorsal horn, thereafter c-fos protein in the deep layer of spinal dorsal horn were expressed. CGRP and substance P immunoreactive neurons were decreased markedly 1 week after neuropathic pain model operation.

The findings of special medical examinations are not infrequently summarized in the form of health classification. This procedure seems valuable for the protection of workers'health from personal health as well as public health point of view, because health classification of workers provides occupations health workers with birds eye view informations in terms of medical, placement and educational procedures, which are to be followed after medical examinations. In this study, the authors have reviewed the existing systems of special medical examinations and Health classifications in different countries and those recommended by international organizations for the purpose of improving the current system in Korea. The important issues covered in this review in relation to health classification of workers included the categories of diseases, the examination and laboratory tests, the criteria for health level classification and the health instructions to be given at each health levels. It was found that the current health classification system in Korea could be featurea as follows : 1. Special medical examinations are always carried out in combination with general medical examinations, contributing to the detection of risk factors of occupational diseases. 2. The selection of examinees is always made on the basis of work environment monitoring, often resulting in the underdetection of exposed workers. 3. Even if the test items are properly selected according to the principles of occupational medicine, further review is required in the light of recent advances in the pathogenesis as well as early changes of occupational diseases and epidemiologic principles. 4. The criteria for the classfication of health levels are to be reviewed on the basis of clinical epidemiology. 5. The health instructions covered only medical and placement aspects, failing to introduce the concept of health promotion.

We report a 57-year-old man with bilateral cranial nerve IX and X palsies who presented with severe dysphagia. After a mild head injury, the patient complained of difficult swallowing. Physical examination revealed normal tongue motion and no uvular deviation. Cervical X-ray findings were negative, but a brain computed tomography revealed a skull fracture involving bilateral jugular foramen. Laryngoscopy indicated bilateral vocal cord palsy. In a videofluoroscopic swallowing study, food residue remained in the vallecula and pyriform sinus, and there was reduced motion of the pharynx and larynx. Electromyography confirmed bilateral superior and recurrent laryngeal neuropathy.
