BACKGROUND: It has been found that sterss challenge with heat shock produces the acquisition of cellular resistance to ischemin injury in the hearts, which is associated with stress protein induction. The conventional heat shock(42degrees C of rectal temperature for 15min, anesthetized animal), however, is strong enough to endanger the animal life and then not suitable for practiocal application in human. The present study was performedd in an attempt to search the safely applicabel stress modalities to acquire the myocardial tolerance to ischemia-reperfusion in jury. METHODS: Male, Sprague-Ddawley rats(200-250g) were exposed to various stressful conditions, such as heat stimulation(environmental temperature of 42degrees C for 30min, live animal), swimming(20min), immobilization(60min), treadmill exercise(20M/min, 30min) and hyperbaric oxygenation(3atm, 60min) given once a day for 5 days. Twenty-four hours after the last application the hearts were isolated and perfused with oxygenated Krebs-Henseleit buffer solution by Langendorff method. Ischemia-reperfusion injury was produced by 20 min-global ischemia followed by 30 min-reperfusion. Cardiac mechanical function, lactate dehydrogenase release, the induction of stree proteins were assayed and compared dbetween the stressed dand the control animals. RESULTS: Upon reperfusion after ischemia the recovery of cardiac function was significantly improved in the stressed animals. The percentile recovery at 30min of reperfusion was in a range from 55.3%(swimming) to 89.3%(treadmill exercise), which was significantly higher than that of the control hearts(38%). The functional recovery of the conventional heat shocked heart was 57.7%. In stressed animals, lactate dehydrogenase release, which indicates myocardial cell injury, was significantly reduced by 20 to 30% compared to that for the control. The expression of an inducible form of 70 series stress protein, SP72, which was assayed by immunoblotting method, was markedly increased by heat stimulation while the other stress modalities failed to increase, it. There were no appreciable inductions of SP73(constitutive form) and GRR78 in the stressed animals. CONCLUSION: These results suggest that the cardiac protection from the ischemia-reperfusion injury could be induced by the repetitive non-fatal stress stimulations and that SP70 family proteins may be partly involved in the cardioprotective effect produced by heat stimulation, but not play the essential roles in anti-ischemic effects produced by other stress modalities.

The age of puberty represents a very critical time in the life history of every young woman. The menarche stands as primary indicator of the onset of sexual maturation in females. According to several studies, menarcheal age in Korean girls has dropped from about 15 years of age in 1960s to 13.5 years of age in 1980s. This findings show a pronounced secular trend to earlier maturation. The purpose of this study is to determine (1) the average age at menarche in Korea in present time, (2) the secular trend of menarcheal age, and (3) the geographic regional influence on menarche. The data sampling was obtained from the physical examination cards of women students in Yonsei University who entered from 1983 to 1991. The data which was obtained from the number of 7761 was analysed by dBase III plus and SAS program. The results are as follows: 1) The mean menarcheal age of the subjects was 13.7+/-1.2 years. 2) Age at menarche has been getting earlier by some 7.4 months during the period of recent II years. 3) Comparing to the decreasing secular trend of menarcheal age, the height and weight showed increasing trend. 4) There were significant differences in menarcheal age, height, weight among geographic regions. We conclude that the results indicate an accelerating secular trend in age of menarche in Korea.

Purpose: The purpose of this study was to examine the effects of a video education program in women receiving high-intensity focused ultrasound(HIFU) treatment. Methods: This was a quasi-experimental study with a nonequivalent control group non-synchronized design. The participants were 54 patients who had benign uterine tumorsand adenomyosis. The data were collected from June to August 2018. The experimental group was provided a video education program with a question-and-answer session for 10 minutes after viewing the video. A 10-minute video education program on HIFU and post-procedural care was developed based on the literature.The control group received usual care (i.e., verbal instructions on post-procedural care). The questionnaire survey was conducted twice: before the educational program and before being discharged from the hospital. Differences in uncertainty, emotions, and self-efficacyamong patients were analyzed. Data were analyzed using the chi-square test, the t-test, the Shapiro-Wilk test, the paired t-test, and the t-test with SPSS for Windows version 23.0. Results: The participants in the experimental group showed a decrease in uncertainty(t=4.33, p<.001), improvements in anxiety(t=–4.07, p<.001) and depression(t=–3.55,p<.001),and an enhancement ofself-efficacy(t=–4.39,p<.001) compared to the control group. Conclusion This nursing intervention was effective at reducing uncertainty, improving emotions, and enhancing self-efficacy. We hope that it will be applied to improve nursing practice and that it will be valuable when utilized for helping patients to choose a treatment method.

Congenital adrenal hyperplasia is inherited disorder of adrenal steroidogenesis. 21-hydroxylase deficiency is the most commone enzymatic defect and is divided into classic and late-onset or nonclassic forms. Both classic non-classic 21-hydrozylase deficiencies are inherited in a recessive manner as allelic variants. But it is rare that happened in twin infants. Chief complaints of affected twins in our case were ambiguous genitalia, hyperpigmentation and dehydrations. They were revealed into hyponatremia, hyperkalemia and increased amount of serum progesterone, 17-hydroxyprogesterone and urinary 17-ketosteroid excretion and were administered with DOCA, 9alpha-fluorohydrocortisone, hydrocortisone to control the electrolyte imbalance. And now, both of them are going to normal ratio of weight gain and body growth.

Scaphoid fractures are the most common fracture and early diagnoses are very important because of preventing from serious complications such as nonunion, avascular necrosis, and disability of wrist joint. There are a few reports of clinical survey of scaphoid fractures, but not to be reported the evaluation for the close relation among mechanism, modes of treatment, especially operation and late complications. This paper reports more clear corelationships among them as mentioned as above through clinical study of scaphoid fractures. The authors have surveyed the clinical study of 26 cases of scaphoid fractures from July, 1983 to November, 1989 at Department of Orthopedic Surgery, Haewha hospital of Korea University. The following conclusions were obtained through clinical survey. 1. Among 26 cases, they were 25 males and one female between 20 and 50 years of age, and ocalization was 16 in right and 10 in left. They were 21 fresh fractures and five nonunions. 2. Mechanism of injuries had revealed fall down or slip down in 13 cases, roller injury in five cases, fisting injury in four cases, direct trauma in two cases, and traffic accident in two cases. Fracture loeation was four cases in proximal 1/3, 17 cases in middle 1/3, and five cases in distal 1/3. 3. Operations using volar approachs in 12 cases and dorsal approachs in three cases had been done for ten cases of displaced fresh fractures and five cases of neglected nonunions. 4. Eleven undisplaced fresh fractures were treated with short arm thumb spica cast but one with. long arm cast. Of ten displaced fresh fractures treated by open reduction, seven cases were treated with Herbert screw, two cases with K-wire, and one case with treated by open reduction and bone graft with Herbert screw fixation in three cases, K-wire fixation in one case, and open reduction with bone graft in one case. 5. Unions were obtained at average 11.5 weeks in eight of 11 cases treated with conservative treatment for fresh fractures, 12 weeks in eight of 10 open reduction cases of fresh fractures, and 20 weeks in three of five neglected nonunion cases. 6. Of eleven conservatively treated cases, two cases resulted in nonunion and other one case in avascular necrosis. Of ten treated with open reduction, one complicated in delayed union, other one nonunion. Of five neglected nonunion cases treated by open reduction added with bone graft, one remained in nonunion and other one case complicated with arthritis and nonunion.

Objectives: The suicide rate in Korea is one of the highest among all members of the Organization for Economic Cooperation and Development. Gatekeeper training is one of the major projects for the national suicide prevention strategy in Korea. The Gatekeeper Behavior Scale (GBS) is a self-reported questionnaire used to evaluate the effects of gatekeeper training. This study aimed to validate the Korean version of the Gatekeeper Behavior Scale (K-GBS). Methods: The GBS was translated into Korean, then back-translated to the original language to verify the translation accuracy. Nine hundred middle and high school teachers who participated in gatekeeper training for suicide prevention were included in this study. The construct validity was tested using confirmatory factor analysis. The internal consistency was assessed using Cronbach’s alpha. Results: Confirmatory factor analysis showed that the K-GBS comprised of three factors (preparedness, likelihood, and self-efficacy) with an acceptable model fit (Tucker-Lewis index=0.99, comparative fit index=0.99, root mean square error of approximation=0.03). The Cronbach’s α coefficients were 0.95 for the total scale, 0.94 for preparedness, 0.89 for likelihood, and 0.93 for self-efficacy. Conclusion The K-GBS showed good construct validity and internal consistency. Therefore, it can be a useful tool for assessing the effects of gatekeeper training on suicide prevention in Korea.

Choriocarcinoma is a relatively rare malignancy of which characteristic is rapid metastasis to the other organs. It is related to the previous gestation or originated from the teratoma. Choriocarcinoma is mostly originated from the intrauterine chorionic villi, but it is rarely originated from the utreine cervix, fallopian tube, ovary, vagina and pelvic cavity. Primary choriocarcinoma of the fallopian tube is exceedingly rare and it is originated from ectopic tubal pregnancy, tubal migration from the intrauterine pregnancy or intratubal teratoma. 9 Symptoms and signs of the choriocarcinoma originated from the ectopic pregnancy are abdominal pain, vaginal bleeding, palpable adnexal mass, positive pregnancy test and amenorrhea. Thus it is difficult to distinguish choriocarcinoma from ectopic pregnancy on the basis of symptoms before the microscopic diagnosis presented.20 Effective treatment of choriocarcinoma is chemotherapy. Additional operation is possible. B-HCG is a useful measure for the follow up. We experienced a 36-year-old multigravida Korean woman who was diagnosed as the rupture of ectopic pregnancy after left salpingectomy in our hospital and then confirmed primary choriocarcinoma of the fallopian tube without metastasis on microscopic finding. Postoperative chemotherapy was performed with methotrexate. The follow up of disease is still on going at two month intervals and she has remained healthy, We report this case with review of literatures.

Intracranial lipomas located in the cerebellopontine angle are extremely rare. These tumors are maldevelopmental lesions which can cause slowly progessive neurological symptoms. The clinical management of these tumours differs significantly from other lesions in this region. A 45 year old man presented with a 3-month history of vertigo and tinnitus in the left ear. In T1-weighted magnetic resonance imaging, the lesion was hyperintense and did not enhance after application of gadolinium. The patient was treated with medical therapy with good response. We present a review of the literature, with particular regard to management. Conservative treatment is recommended and limited surgery is usually indicated if the patients suffer from disabling neurological symptoms and signs e.g., vertigo, nausea, trigeminal neuralgia, facial weakness or facial spasm.
