BACKGROUND: It is well known that neuronal degeneration can occur after a brief deprivation of energy source. To investigate whether glial astrocyte can induce a phenomenon of delayed cell death after transient energy loss and to see how different are the effects of nifedipine, lidocaine, carnosine and hypothermia on delayed toxicity in astrocyte. METHODS: Human astrocytoma cells (U1242MG) were used in this study. To assess the astrocyte survival during post-ischemic period after transient histotoxic hypoxia, 3-[4,5-dimethylthiazol-2yl]-2,5, diphenyl tetrazolium bromide (MTT) test was used. Compared to MTT test, tryphan blue test was also used to demonstrate membrane damage of affected cells. Studies on intracellular calcium dynamics during ischemic and post-ischemic period were carried out with fluo-3 and flow cytometry system. RESULTS: The percentage survival of astrocyte during post-ischemic period was decreasing with time. Calcium channel blocker nifedipine, sodium and calcium channel blocker lidocaine and free radical scavenger carnosine could not prevent post-ischemic cell damage. But, hypothermia was only an effective method in ameliorating post-ischemic cell death. Intracellular calcium increase during ischemia and post-ischemia was dependent on extracellular calcium influx. CONCLUSIONS: Only hypothermia was effective in reducing astrocyte death during post-ischemia after transient energy depletion. Intracellular calcium alterations during post-ischemia was from extracellular space.

4.Effects of Active Mandibular Exercise for Mouth Opening Limitation Patients after Maxillomandibular Fixation Release: A Non-Randomized Controlled Trial
Journal of Korean Academy of Nursing 2018;48(1):26-37
PURPOSE: The aim of this study was to evaluate the effects of active mandibular exercise (AME) in patients with limited mouth opening after maxillomandibular fixation (MMF) release. METHODS: The study used a quasi-experimental, nonequivalent control group and a pre test-post test design. Sixty-two patients with Maxillomandibular Fixation Release were assigned to the experimental (n=31) or control group (n=31). The AME was performed in the experimental group for 4 weeks. The exercise AME consisted of maximal mouth opening, lateral excursion and protrusive movement. These movements were repeated ten times a day. After the final exercise of the day, the number of tongue blades used for mouth opening was noted. The effect of AME was evaluated after MMF release at different time intervals: a) immediately, b) after 1 week, c) after 2 weeks, d) after 4 weeks, and e) after 12 weeks. The exercise was assessed using the following criteria: a) mandibular movements, b) pain scores associated with maximal mouth opening, c) discomfort scores associated with range of movement, and d) daily life activities that involve opening the mouth. RESULTS: The experimental group showed significant improvement regarding the range of mandibular movements (maximal mouth opening (F=23.60, p < .001), lateral excursion to the right side (F=5.25, p=.002), lateral excursion to the left side (F=5.97, p=.001), protrusive movement (F=5.51, p=.001)), pain score (F=39.59, p < .001), discomfort score (F=9.38, p < .001). Daily life activities that involve opening the mouth were more favorable compared to those in the control group. CONCLUSION: The AME in patients after MMF release is helpful for increasing mandibular movement range, decreasing pain and discomfort, and improving day life activities that involve opening the mouth. Therefore, AME is highly recommended as an effective nursing intervention.

First rnany years there has been a great dea,l of disagreement about the classification and histology of recalcitrant pustular eruptions of the palms and soles and the rela.tion of this condition to psoriasis. It ia the purpose of this investigation to describe histological changes in fresh pustules from patients witb pustular eruptions of the palms and soles and compare these changes between patients with clinically preceding or co-existing psoriasis (4cases) and without clinically preceding or co-existing psoriasis (7cases). Nine biopsies of pustules were exarnined and the results were compared between two groups. Histopathological findings were otherwise uniform and typical intradermal well-delineated pustules. No significant differences were found bet.ween th two groups. In view of the uniforrn histology, the unknown etiology, and uncertain clinicaI classification, the authors prefer the clearly descreptive term pustulosis palrnaris et plantaris(PPP). Recent;ly the phagocytic ability of neutrophilic leukocytes was reported to be impaired in patients suffering from pustular eruptions of the palms and soles. In our study this ability was performed with the aid of the NBT. dye reduction test before and after administration of Descresept (aristolochic acid). The aim of the present study was to observe the effect of Descresept on NBT test in relation to the clinical acitivity of PPP. The results were as follows: l. In 6 of 11 patients, clinical improvement was accompanied with increasing NBT' scores. 2. In 2 of 11 patients, clinical aggravation was noted in spite of Descresept adrninistration. In these 2 cases, increase in dosage of Descresept made clinical improvement again with increasing NBT scores. 3. In 3 of the 11 patients, there was noted clinical improvement, but NBT scores were slightly decreased.

We evaluate the psychosocial characteristics and primary reason for electing operation in myopic patients who were candidates for photorefractive keratectomy (PRK). The questionnaire data were collected on PRK patients and compared them with similar group of myopia. Most of the PHK patients were unmarried female in their twenties. The most striking demographic chracteristic of PRK sample was that the high proportion of them was highly educated office worker with high socioeconomic status. They were in possession of extroversive character rather than introversive one. They thought that their visual acuity was very serious, and preferred wearing contact lens for visual correction. The most important reason for undergoing PRK was avoiding inconveniences of contact lens or glasses. The other reasons were improving vision, improving appearance, and hoping to change life style with better vision. They were afraid of unpredictability of visual recovery and occurrence of complications, after operation, The results of this study may help analyze the factors that influence the success of PRK and patient's satisfaction.

Loss of best corrected visual acuity(BCVA)is a landmark of safety, as one of important complications of refractive surgery. To evaluate causes of 2 lines or more loss of BCVA after laser in situ keratomileusis(LASIK), 206 eyes of 139 patients, who had undergone LASIK and had been followed up for 6 months or more, were included in this study. During the follow-up, nineteen eyes(9.2%, 19/206)showed 2 lines or more loss of BCVA postoperatively. The causes of BCVA were irregular astigmatism(15 eyes, 7.3%), retinal complications(3 eyes, 1.5%), and infectious keratitis(1 eye, 0.5%). All irregular astigmatisms had occured within 1 month postoperatively and 13 eyes of all 15 eyes spontaneously recovered after postoperative 3 months. The persistent loss of BCVA occurred in 5 eyes(2.4%, 5/206). Three cases of all 5 persistent losses of BCVA were due to retinal complications. In conclusion, our results suggest that the most common cause of loss of BCVA after LASIK is irregular astigmatism. Irregular astigmatism is a temporary situation which has a tendancy of spontaneous recovery. Thus careful observation is recommended in irregular astigmatism after LASIK. The retinal complications of LASIK may lead to permanent loss of BCVA. Therefore it is needed to examine preoperative fundus closely and to explain possible postoperative complicaitons to the patients and their family.

The purpose of this study is to explore perception types and to understand the nature of experience of nursing students' clinical education by using the Q methodology. A Q sample was developed through a review of the literature and descriptions about nursing students' experience in clinical practice. Thirty-six statements made up the finalized Q sample. The P sample consisted of 33 third grade nursing students in K university. Q statements were written on separate cards and were given to the 33 subjects to sort according to degree of agreement or disagreement. The Q-sorts by each subject were coded and analysed with the Quanl PC program. A a result, three major perception types, namely, 'alienation of ideal and reality'

Journal of Korean Academy of Nursing 1998;28(2):369-379
Despite acknowledgment that pain is likely to be a major problem for many older adults, it is difficult to estimate the frequency of pain problems for this population. The main purpose of this study was to identify the various characteristics of chronic pain in the elderly by gender. It examines by gender, pain frequency, pain intensity, number of chronic pain sites, localization of pain, impact on activities, methods of pain management, and effects of chronic pain management. The subjects were 189 elderly people(65 years and older) living in an urban area. They were surveyed at their homes. They were surveyed by interview using a closed-ended questionnaire. The survey was done from Nov. 6th. to Dec. 6th. 1997. Descriptive statistics were used to determine all of the reported pain variables. Chi-square tests were used to determine crude differences between pain intensity and gender. T-test was used to determine differences in number of pain sites between men and women. The findings are as follows ; Of the 189 subjects, 83.6% reported experiencing pain, and men reported a lower prevalence(69.5%) than women(89.2%). Women had significantly more severe pain than did men(p=.001). Lower back pain(20.2%) and leg pain(20.2%) were the most prevalent, followed by knee pain(17.4%), arm pain(13.3%), neck and shoulder pain(11.6%), and headache(9.9%). Women experienced more multiple localizations of pain(p=.0001). The greatest impact was on movement(83.5%), followed by usual activities(60.8%), sleep(49.4%), visiting(29.1%), and hobbies and recreations(50.0%). No differences were observed between men and women in the proportion of subjects reporting a negative impact on each of these activities. The methods of pain management were hospital visit(70.9%), drug store medication(46.7%), oriental medicine clinic(32.9%), endurance(13.3%), self-management(6.3%). Drug therapy was the most effective pain management strategy(94%), followed by physical therapy(63%) and accupuncture byssocausis(55%). The conclusion: Pain is a symptom of great clinical importance that is often associated with disability, loss of independence, and reduced quality of life. In this study chronic pain symptoms were common but unevenly distributed in men and women. The results further advance understanding of the experience and impact of pain by gender. Future studies should incorporate questions that gather systemic and more detailed information on the characteristics of pain, expecially by gender and by age.
