This study was conducted to measure the degree of Korean Gender Egalitarianism among the students from six different high schools(132 girls, 127 boys) in Sunchon si, Chunnam province from Dec. 7th to Dec. 15th in 1999. The survey on gender egalitarianism was done in relation to the public understanding of the subject matter, parents' hug times, and parent's communication skills. Korean gender egalitarianism scale was standardized by Korea Woman Developmental Institutes in 1999. The data was analyzed by SAS program. Results were as follows: 1) Generally, girls are more conscious of gender egalitariannism than boys(t=-13.79, p < .001). Above all, the younger the students are, the more they feel equal(F=8.01, p < .01). In sibling cases, two sisters have the highest level of gender egalitarianism while two brothers have the lowest level of gender egalitarianism(F=9.20, p < .001). Students who come from religious families are more inclined to demonstrate gender equality(t= 2.42, p < .05). However, there is no diffrence in relation to the parents' ages or academic background or harmony within the family. 2)There is no difference that girls and boys generally communicate with their parents. In ages, 17 years old students communicate more than 18, 19 with parents(father F=3.97 p < .05?mother F=5.31, p < .01). That is, the younger students can communicate with their mothers more often than the older ones. In sibling cases, two sisters have more openly communication to parents while two brothers have(F=2.84, p < .05). Students communicate with their parents regardless of parents' academic background. But those from the family in harmony have more open chance to communicate than those who are not in hamony(father F=21.66, p < .001?mother F=13.37, p < .001). They can comm -unicate with their parents better when their fathers hug them than when they didn't get hugs(father t=-4.76, p < .001? mother t=-2.34, p < .05). They can also communicate with their patents better when their mothers hug them once or more than when they didn't get hugs(father t=-3.78, p < .001?mother t=-5.64, p < .001). 3) There is no diffrence whether the father hugs or not, but the mother's hug is very important because students whose mothers hug them once or more have significantly more gender egalitarianism than those students whose mothers didn't do(t=-3.98, p < .001). Based upon these results, it is recommended that we reconsider the role of gender in the socialization of high school students and also include gender egalitarianism in sex education. In this context, further study should be done for the improvement of students' communication within the framework of egalitarianism based upon parents' hugs(semi-language). Continued study is especially important in regards to the mother's hug and its enhancement of the students' gender egalitarianism.

BACKGROUND: Home ventilation can decrease hospital-acquired infection, increase physical activity, improve nutritional status, enhance quality of life, and reduce medical costs. The number of patient using home ventilators has been increasing, particularly in Europe and United States. Although the number of patients with home ventilation has been increasing in Korea, the current status of these patients is not well known. This study was undertaken to obtain basic information upon these patients in additon to evaluating any problems related to patients' home care in our country. METHODS: A register of 92 patients with home ventilators in Seoul and Kyunggi province were obtained from commercial ventilator supply companies. The patients were contacted by phone and 29 of them accepted our visit. Information concerning education about home care before discharge, equipment cost, and problems related to home care were documented. The mode and preset variables of the home ventilator were checked; tidal volume (TV), peak airway pressure, and oxygen saturation were measured. RESULTS: There were 26 males (90%) and their mean age was 48.0(±20.1 years. The underlying diseases were: 21 neuromuscular disorders, 2 spinal cord injuries, 6 chronic lung diseases. Among the caregivers, spouses (n=14) predominated. Education for home care before discharge was performed primarily by intensive care unit nurses and the education for ventilator management by commercial companies. Twenty-five of the 29 patients had tracheostomies. Volume targeted type (VTT;n=20, 69%) was more frequently used than the pressure targeted type(PTT). Twenty-three of the 29 patients purchased a ventilator privately, which cost 7,450,000(±3,290,000) won for a PTT, and 14,280,000(±3,130,000) won for a VTT. Total cost for the equipment was 11,430,000(±634,000) won. The average cost required for home care per month was 1,120,000(±1,360,000) won. CONCLUSION: The commonest underlying disease of the patients was neuromuscular disease. The VTT ventilator was primarily used with tracheostomy. Patients and their families considered the financial difficulties associated with purchasing and maintaining equipment for home care an urgent problem. Some patients were aided by a visiting nurse, however most patients were neglected and left without professional medical supervision.

PURPOSE: Organotypic slice cultures are suitable for morphological and electrophysiological studies, and a valuable method to evaluate physiological and pathological responses to external stimuli. This study was designed to establish a method and to assess its values of organotypic slice cultures of rats' hippocampus for neuroscience research. METHODS: 8-day-old neonatal Sprague-Dawley rat's brain was dissected quickly and the brain was removed. Both of the hippocampi were dissected out in Petri dishes and placed on a chopper or tissue cutter with Gey's balanced salt solution(GBSS). Slices of 450 micrometer were cut and separated by adding of a drop of GBBS. Extra GBBS was aspirated. Transfer tissue slices of Millicell membrane were inserted in six-well plates containing 1 mL of warmed Gahwiler's media. Six-well plates were placed in an incubator at 36 degrees C with 5% CO2, and the media were changed regularly every 2 to 3 days. Some tissues were placed in 4% paraformaldehyde for staining and others were placed in Phosphate buffered saline(PBS) for 30 min for Western blotting. Then, we stained the free-floating, cryocutting or paraffin embedded slices with H&E or the days of 6, 9, 14 and 24 in vitro(DIV), and evaluated any changes of tissues and neurons by an image analysis system RESULTS: Hippocampal cultures had well-defined cell body layers of dentate gyrus, CA1, 2, 3 and 4 as early as the day of 6 in vitro(DIV). After 14 DIV, the cultures became gradually thinner from 450 micrometer to 150 micrometer. After 21 DIV, there were migrations of cells away from the margins of the slices and degenerative changes of some neuronal cells occurred. But pyramidal cells always were organized in well-defined cellular layer even after several weeks in the culture. Therefore, the best results were obtained by culturing slices of 6 to 14 DIV. Slice cutures was maintained after 4 weeks in vitro, but the oppotunity of contamination and infection increased as the periods of cultures trolonged. In staining, after any tissue was cultured in 2 weeks in vitro, no differentiation of the morphology and distribution in dentate gyrus, CA1, 2 and 3 were seen. In organo-typic slice culture of rats' hippocampus, we witnessed growth of glial and neuronal cell, and found pyramidal and granular cells. NeuN proteins were identified by Western blotting, and the density of NeuN protein bands was at the maximum value on the day of 9 in vitro. CONCLUSION: Since the organotypic slice cultures of rats' hippocampus were similar to the hippocampus in vivo in terms of anatomical and cellular morphology, it will become a valuable method for neuroscience research.

Choroid plexus papilloma is a very rare disease in children. The manifestations of the disease differ according to the tumor size and the location. Increased CSF production by the tumor, hydrocephalus and symptoms of increased ICP are the main symptoms. The first line of treatment is surgical excision, but sometimes excision itself is very difficult due to the site and the size of the mass. Adjunctive radiation therapy or chemotherapy is not recommended. Since gross total resection without adjunctive therapy offers highest likelihood of success. Significant prognostic factors are sex, age, time of diagnosis, the duration between the appearance of symptoms and diagnosis, tumor volume, tumor site and the extent of surgery. We report a case of choroid plexus papilloma, in a child with anorexia and failure to thrive.

BACKGROUND: Although a brachial plexus block can be used to provide anesthesia and analgesia for upper extremity surgery, its effects using MgSO4 on postoperative pain management have not been reported. The aim of this study was to evaluate brachial plexus block using MgSO4 on postoperative analgesia. METHODS: Thirty-eight patients who were scheduled to undergo upper extremity surgery were randomly allocated into two groups: patients receiving axillary brachial plexus block with 0.2% ropivacaine 20 ml and normal saline 2 ml (group S) or 0.2% ropivacaine 20 ml and MgSO4 200 mg (group M). Before extubation, the blocks were done and patient controlled analgesia was started, and then, the patients were transported to a postanesthetic care unit. The postoperative visual analogue scale (VAS), opioid consumption, and side effects were recorded. RESULTS: The two groups were similar regarding the demographic variables and the duration of the surgery. No differences in VAS scores were observed between the two groups. There was no statistically significant difference in opioid consumption between the two groups. Nausea was observed in three patients for each group. CONCLUSIONS: Axillary brachial plexus block using MgSO4 did not reduce the level of postoperative pain and opioid consumption.

PURPOSE: The aim of this study was to investigate the potential effects of mild hypoxia in the mature and immature brain. METHODS: We prepared organotypic slice cultures of the hippocampus and used hippocampal tissue cultures at 7 and 14 days in vitro (DIV) to represent the immature and mature brain, respectively. Tissue cultures were exposed to 10% oxygen for 60 minutes. Twenty-four hours after this hypoxic insult, propidium iodide fluorescence images were obtained, and the damaged areas in the cornu ammonis 1 (CA1), CA3, and dentate gyrus (DG) were measured using image analysis. RESULTS: In the 7-DIV group compared to control tissue, hypoxia-exposed tissue showed decreased damage in two regions (CA1: 5.59%+/-2.99% vs. 4.80%+/-1.37%, P=0.900; DG: 33.88%+/-12.53% vs. 15.98%+/-2.37%, P=0.166), but this decrease was not statistically significant. In the 14-DIV group, hypoxia-exposed tissue showed decreased damage compared to control tissues; this decrease was not significant in the CA3 (24.51%+/-6.05% vs. 18.31%+/-3.28%, P=0.373) or DG (15.72%+/-3.47% vs. 9.91%+/-2.11%, P=0.134), but was significant in the CA1 (50.91%+/-5.90% vs. 32.30%+/-3.34%, P=0.004). CONCLUSION: Although only CA1 tissues cultured for 14 DIV showed significantly less damage after exposure to hypoxia, the other tissues examined in this study showed a tendency towards less damage after hypoxic exposure. Therefore, mild hypoxia might play a protective role in the brain.
