The purpose of the survey was to identify the degree and the relationship of sexual knowledge, sexual attitude. This information will provide useful data for a more systematic, desirable, and practical sex education. The data was collected from 187 first grade schoolchildren(95 boys and 92 girls) of two Junior high school in Chun-nam area. The data was gathered by questionnaire from Oct. 1 to 15, 1996. The questionnaire was modified by authors using the questionnaire developed by You-Jeong, Han(1996). Data was analyzed by using the statistical computer package, SAS to manipulate the data long with percentages, means, standard deviation, t-test, chi2-test, GLM, and Pearson correlation coeffiency. The results in this study were summarized as follows : 1. Sex related knowledge. - The mean score of sex related knowledges showed significant differences between boys and girls(boys ; 22.3, girls ; 21.0, p<0.025), and in the area of pregnancy & delivery(boy ; 9.4, girls ; 7.9, P<0.000) showed significant difference between boys and girls, but in the area of physical differences of the others sex(boys ; 12.9, girls ; 13.1, p<0.551) showed no significant difference between boys and girls. 2. Sex related attitudes. - The mean score of sex related attitudes showed significant difference between boys and girls(boys ; 56.7, girls : 60.5, p<0.002) and in the area of psychological difference the other sex(boys : 28.9, girls : 32.5, p<0.000), but in the areas of form of friendship with the other sex(boys : 11.5, girls : 11.2, p<0.335), sexual delinquency & its prevention(boys : 16.3, girls : 16.9, p<0.171) showed no significant difference between boys and girls. 3. The relationships between sex related knowledges and sex related attitudes. - Those who had higher sex related knowledges showed more positive attitudes towards sex, and showed no statistical significance(r=0.08, p<0.286). 4. Differences of the sex related knowledges according to general characteristics. - The students had disease experience, health interest and more school performance had higher knowledge scores about sex. 5. Differences of the sex related attitudes according to general characteristics. - Those who were in high school performance had higher attitude scores about sex as well.. From the result of the study, it is recommended to develop systematic sex education through formal school education according to age.

Objective To establish the animal model of periventricular leukomalacia (PVL) caused by lipopolysaccharide (LPS) and investigate the immune mechanisms in the pathogenesis of cerebral palsy due to intrauterine infection. Methods Twenty-six mature pregnant Wistar rats were divided into experiment(n= 15)and control groups(n =11). LPS(0. 3 mg/kg) and distilled water were injected on 15 days of gestation to two groups respectively intraperitoneally. One hundred and twenty-eight neonatal rats of experiment group and 105 in the control group were obtained till the gestation day of 21. The level of IL-2, TNF-? and histology changes in neonatal rats' brain were observed by HE staining and RIA, water content in brain tissues were compared. Results IL-2[(3. 56?0. 450) ng/g] and TNF-? concentrations [(8. 23?0. 47)ng/g] in neonatal rats' brain of the experiment group were significantly higher than those in the control group [(0. 78?0. 2)ng/g and (5. 23?0. 32)ng/g, P

Objective To explore clinical characteristics of the digestive tract obstruction due to annular pancreas. Methods We reviewed retrospectively clinical features, operative findings and the autopsy of 5 children with annular pancreas. Results Neonate patients usually present complete upper gastro intestinal obstruction because most of them were complicated with duodenal atresia. Infants present chronic incomplete intestinal obstruction duo to annular pancreas. 35.8% of duodenal constriction was caused by annular pancreas. Conclusions All the symptomatic patients with annular pancreas should undergo exploration to restore the consecution of the digestive tract and to detect if there is a concurrent malformation such as intestinal atresia.

Objective To detect the expression and activation level of nuclear factor ?B (NF-?B) in synovium of rheumatoid arthritis (RA).Method Forty-six specimens including 17 RA, 24 osteoarthritis (OA) and 5 normal synovial tissues were subjected to RT-PCR to determine the mRNA level of NF-?B p65,p50,inhibitor of NF-?B (I?B),interleukin-1? (IL-1?) and matrix metalloproteinase 9 (MMP-9).Thirty-nine sections including 14 RA,21 OA and 4 normal synovium were subjected to immunohistochemistry to determine the expression level of NF-?B p65.Synoviocytes from 14 synovial specimens including 8 RA and 6 OA were cultured and the nuclear protein was extracted and reserved for western blot.Results The mRNA level of p65,IL-1(,MMP-9 were higher in RA group than that of control (P

TNP-conjugated spleen adherent cells (SAC) from normal BALB/c mice could stimulate lymph-node T lymphocytes (LNT) of 1, 3, 5-trinitrobenzene (TNCB) -primed syngeneic mice to proliferate in vitro. The proliferative response was suppressed when phorbol myristic acetate.(PMA) was present in the culture. SAC pretreated with PMA also suppressed markedly the response. Furthermore, PMA was shown to inhibit interleukin-1 (IL-1) production and/or secretion by macrophages in response to LPS stimulation in vitro. Therefore, the suppressive effect of PMA on antigen presentation seems to be due to its inhibitory effect on IL-1 production and/or secretion.

0.05).In the 35 patient who had unitary incontinence before the operation,the symptom disappeared in 6(17.1%) patients,and deteriorated in 2(5.7%).While in the 38 patients without urinary incontinence before the operation,9(23.7%) showed the symptom postoperation.Totally,urinary incontinence was developed in 11 patients after the operation.Conclusions The patients with moderate-to-severe pelvic organ prolapse treated by traditional surgical procedures have a low rate of objective cure and a high rate of recurrent cystocele.It is important to repair the anterior pelvic floor during the operation.And the surgeons should be alert to the possibility of urinary incontinence.

Objective Study the prevention and early diagnosis of severe complications of thoracoscopy. Methods 400 patients,(18～81)years,ASA Ⅰ-Ⅲ,underwent thoracoscoy,including 320 pulmonary bubble resections and 80 thorax,mediastinum or lung tumor biopsy or resections.All patients were anesthetized with one-lung ventilation using a double-lumen tube and monitored continuously in circulatory and respiratory functions with a multi-runctional monitor. Results Severe intraoperative complications occurred in 8 patients,including 5 reexpansion pulmonary edema,1 complete occlusion of double-lumen tube due to massive pleural effusion,1 massive bleeding and 1 cardiac arrest due to bilateral pneumothorax.All complications were successfully treated and the patients were cured and discharged. Conclusions Thoracoscopy must be well prepared.Applying one lung anesthesia with double-lumen tube,careful observation during operation,early recognition and treatment of complications may contribute to assuring the safety of this procedure.
