In systemic hypertension, capillary resistance is highly elevated and' contractility of vascular smooth muscle is elevated. This is due to increased calcium uptake into the sarcoplasmic reticulum of the vascular smooth muscle. Recently, nifedipine, an antihypertensive medication which inhibits calcium uptake into the vascular smooth muscle is commonly used. It decreases the contractility of the vascular smooth muscle and causes the vessels to relax, which in turn lowers the blood pressure. In 1987, according to Rodriguez-Sargent et al. the increased incidence of cataract in Dahl-salt sensitive rats(DSR) was due to increasd water and sodium contents and decreased potassium content. In this investigative study on hypertension, the water, Sodium and potassium contents in Spontaneous Hypertensive Rats(SHR) were measured. After treatment with nifedipine in SHR, we observed decreased blood pressure along with the changes in water, sodium and potassium contents of the lenses. The following results were obtained from our experiments. 1. In normal SDR, The blood pressure did not decrease with nifedipine injection. 2. After 3-7 days of nifedipine injection bidaily, the blood pressure of SHR did not decrease. 3. After 2 weeks of nifedipine injection bidaily, the blood pressure of the SHR decreased slightly and after 4 weeks of nifedipine injection bidaily, the blood pressure of SHR decreased significantly. 4. Water and sodium contents of SHR were higher than that of SDR and the potassium content was similar to that of SDR. 5. The elevated water and sodium contents of SHR decreased along with decrease of blood pressure, and after 2 weeks of nifedipine injection, showed similar level as the contents of SDR lenses. 6. Potassium contents of SHR lenses showed no change were similar to SDR lines except the 4 weeks nifedipine injection group which showed higher potasslum contents.

As a contrast to the surgery described in part I, a lamellar undermining was performed in a conventional way. The sclera was lamellarly undermined on the retinal hole areas which extended at least 3 mm beyond the disc edge of the retinal breaks. If the scleral buckling with a circling element is indicated the location of the undermined area determines whether the circling band must follow the globe's equator or another great circle around the eye, The technique for decreasing a vitreoretinal traction used in this series of cases was that proposed by Schepens. Of 56 surgical procedures for retinal detachment, there was a case of an unsuccessful closure of the retinal break due to fishmouthing of the posterior edge of the break. The technique proposed by Schepens was sufficiently promising. But it has the following drawbacks; difficulties in exact hole localization in a high detached retina, anchoring sutures of the circling band behind the equator and problems to protect the vortex veins from the circling band etc. Our experience since 1978, led us to modify the conventional view, in favor of the circumferential buckling on the equator.

PURPOSE: The purpose of this study was to investigate the construct equivalence of the five general factors (subjective health, eating habits, physical activities, sedentary lifestyle, and sleeping behaviors) and to compare the latent means between male and female middle school students in Incheon, Korea. METHODS: The 2008 Korean Youth Risk Behavior Survey data was used for analysis. Multigroup confirmatory factor analysis was performed to test whether the scale has configural, metric, and scalar invariance across gender. RESULTS: Configural invariance, metric invariance, and factor invariance were satisfied for latent means analysis (LMA) between genders. Male and female students were significantly different in LMA of all factors. Male students reported better subjective health, consumed more fast food and carbonated drinks, participated in more physical activities, showed less sedentary behavior, and enjoyed better quality of sleep than female students. CONCLUSION: Health providers should consider gender differences when they develop and deliver health promotion programs aimed at adolescents.

PURPOSE: The purpose was to investigate the physiological parameters and health perception of adults in Kyungi province area, and the correlation between these variables. The subjects were 95 adults who participated voluntarily in the health examination program. Methods: The instruments for this study were physiological parameters, which were composed of blood pressure, blood sugar, and body fat. The health perception scale developed by Ware (1976), and the health practice performance scale developed by Chang et al. (1999). Results: The average blood pressure was 137/85mmHg, the average blood sugar was 108.56mg/dl, and the average body fat arm sunt was 27.08% in males, and 30.07% in females. There were significant negative correlation between health perception and blood sugar (r=-2.36, p=.01), and body fat (r= -2.77, p=.001). There were significant positive correlations between blood pressure and health behavior (r=2.76, p=.001). However a significant correlation between health perception and health behavior was not found. Of the sociodemographic characteristics, sex (F=5.42, p=.01), and marital status (F=3.29, p=.04) were related to blood pressure. Also sex (F=4.17, p=.04) was related to body fat, and sex (t=4.04, p=.03) was related to health perception and disease status (t=4.33, p=.040). Thus having a relationship with health behavior. CONCLUSION: It is suggested that health perception provide important information about health status. However, this study has not shown a correlation between health perception and health behavior. Therefore further research is needed to find the other variables related to health behavior.

Alveolar soft-part sarcoma is a rare malignant neoplasm. It occurs most commonly in the deep tissue of the extremity, particularly in the anterior aspect of the thigh. It usually presents as a slow-growing, painless mass with little functional impairment. Because of the relative lack of symptoms, it may be easily overlooked. The course of the disease tends to be long but unrelenting, and local recurrences are frequent. There were no lifetime cures in the reported cases. This tumor is relatively unknown to orthopaedic surgeons, and a wider knowledge of its characteristics may lead to its more frequent recognization, Recently, two cases of alveolar soft-part sarcoma were encountered on the orthopaedic department of Dong-kang Hospital, Ulsan. In case 1, the tumor was found in the vastus lateralis muscle; and in case 2, vastus intermedius muscle. The authors will present these cases in detail to provide a glance at this very rare but more frequently recognizable tumor, the alveolar soft-part sarcorna.

PURPOSE: The purpose of this study was to propose a revised Clinical Ladder System(CLS) Model for nurses based on the evaluation of clinical competence and professional activities of nurses working in general hospitals. METHODS: Data were collected between September 10 and October 30, 2017. Participants were 50 head nurses from 10 general hospitals with over 400 beds located in Seoul City and Gyeonggi Province. Each head nurse evaluated clinical competence, qualifications, and professional activities of 5 staff nurses at each of the 5 levels of CLS in her unit. The total number of the nurses evaluated was 245. Data were analyzed with descriptive statistics and t-test, one-way ANOVA, and Scheffé. RESULTS: Over 80% of the nurses were university graduates. As the CLS levels increased, clinical competence, qualifications, and professional activities also increased significantly. Education material development and quality improvement activities were carried out by nurses from level 2, research and evidence based practice activities were carried out from level 3, and nurses at level 4 or 5 participated in most of the professional activities as leaders. CONCLUSION: In order to retain excellent nurses in general hospitals, recognizing and rewarding nurses according to the revised model of the CLS are recommended.
