This study was designed to examine the effects of Salicornia herbacea L. (glasswort: GW) on the lipid peroxidation and mineral levels in diabetic rats. Diabetes mellitus was induced in male Sprague-Dawley rats weighing 200-220 g by an injection of streptozotocin (STZ) dissolved in a citrate buffer into the tail vein at a dose of 45 mg/kg of body weight. Sprague-Dawley rats were fed an AIN-93 recommended diet and the experimental groups were fed a modified diet containing 10% and 20% of glasswort powder for 4 weeks. The experimental groups were divided into 6 groups which consisted of normal (N)-control group, N-GW 10% and N-GW 20% treated groups, STZ-control, STZ-GW 10% and STZ-GW 20% treated groups. The rats' liver and muscle glycogen, liver and kidney protein, cholesterol and triglyceride (TG) in liver, malondialdehyde (MDA) in liver and kidney values were measured, along with the hepatic of chromium (Cr), iron (Fe), and zinc (Zn) content. The liver glycogen levels was significantly affected in N-GW 20% group among all the experimental groups. The liver MDA levels of the STZ-GW 10% and STZ-GW 20% groups were significantly lower than for the STZ-control group. There were significant differences between the N-control group and the STZ-control group in the hepatic of Zn levels. The hepatic of Cr levels in the N-GW 20% and STZ-GW 10% and STZ-GW 20% groups were significanly higher than for the each control groups. These results exhibited dose related effect of glasswort and it may have favorable influence on lipid peroxidation in the liver.

It has been approximately 40 years since $Br{{\aa}}nemark$ first introduced osseo-integration for implants in the early 1960s. Unlike crown and bridge or denture treatment, implant treatment helps preserve existing bone and improve masticatory functions. Thus, the awareness of implant treatment has grown rapidly among dentists and patients alike in Korea, as it becomes a widely accepted treatment. The following results on patients type and implant distribution were compiled from 1814 implant cases of 640 patients treated at the periodontal dept. of Y University Hospital during 1992 to 2001. 1. There are no dissimilarities between men and women, with patients in their 40,50s accounting for 49% of patients and 56% of implant treatments; the largest share of patients and implant treatments. 2. Mn. posterior area accounted for 59% of implant treatments followed by Mx. posterior area(21%), Mx anterior area(l4%) and Mn anterior area 2%. 3. Partial edentulous patients treated by single crown and bridge-type prosthesis accounted for 98% and fully edentulous patient accounted for the remaining 2% 4. The major cause of tooth loss is periodontal disease, followed by dental caries, trauma and congenital missing. Compared to women, men are more likely to suffer from tooth loss due to periodontal disease. Also, older people are more likely to suffer from tooth loss due to periodontal disease rather than dental caries. 5. The distribution of bone quality for maxillae was 52% for type III, followed by 23% for type II, 20% for type IV and 0% for type I. As for mandible, the distribution was 52% for type II, followed by 37% for type III, 7% for type IV and 4% for type I. 6. The distribution of bone quantity for maxillae was 49% for type C, followed by 34% for type B, 14% for type D, 3% for type A, and 0% for type E. As for mandible, the distribution was 52% for type B, followed by 35% for type C, 6% for type D, 3% for type A and 0% for type E. 7. The majority of implants were those of 10-14mm in length (80%) and regular diameter in width (79%). The results provided us with basic data on patient type, implant distribution, bone condition, etc. We wish that our results coupled with other research data helps assist in the further study for better implant success/survival rates, etc.

Korea fertility level has dropped since the 1960's and speed of decline has accelerated in the 1980's. In the resuls, the growth rate reached to less then 1 percent in 1990 and will be $\ulcorner$0 $\lrcorner$ percent growth in 2021. The total population will increase to 50, 586 thousand persons in 2021 then will decrease. With the rapid fertility decline the age structure of Korean population has changed : while the proportion of child population aged 0-14 is decreasing sharply, that of old-age population aged 65 and over is increasing. Because of the recent increase of sex ratio at birth, the sex structure among the young generation has been destorted; the sex ratio at age 0-4 was as high as high as 112.0 in 1990. The effects of these population phenomena on Korean society are the followings: 1) Old age dependency ratio is increasing rapidly and continuously and will be about 40.0 from the 2050's. 2) Because of the rapid decline of the number of births, the absolute number of the major labour force at age 25-34 will decrease after around 2000 and then from the 2010's become less than that in 1990. 3) Since the large fertility defferentials by womens's educational level have continued and the relation between the educational levels of mothers and children are very strong, level has dropped among higher educated women first when the average fertility level has declined in Korea, the average educational level of the children is may be expected to be relatively low and then the future productivity is will be also low, which causes the decline of 'quality of population. 4) When the high sex ratio at birth (over 110 since 1986) continues, number of brides will be short by over 20 percent from the 2010s, which will bring various kinds of social prblems. Therefore, the counter measures in concrete to relieve the heavy problems are recommended as follows: 1) The extention of the birth intervals, which helps to drop the population growth rate at the same level of number of children per women. 2) The positive supports for out-migrants, which helps to reduce the population size without any destortion of age-sex structure. 3) The defferent supports of family planning for the higher and lower classes, which helps to reduce the gaps between different ferility levels of the classes and to keep and improve the quality of population. 4)population education for both students and adults, which helps to minimize the gap between the private and public requirements.

It is now apparent that many cases of amenorrhea. oligomenorrhea. corpus luteum deficiency, galactorrhea, and infertility are due to hyperprolactinemia. We investigated the relationships between serum prolactin values and factors such as menstrual pattern, frequency of galactorrhea etc, in 135 hyperproIactinemic patients at the Seoul National University Hospital during a period of 6 years, from January, 1979 to December, 1984. The results was as follows: 1. Menstrual pattern changed according to the serum prolactin level. The frequency of amenorrhea is 1.7 percent in patients with serum prolactin levels ranged from $25{\sim}40ng/ml$, whereas 72.4 percent in patients with serum prolactin levels above 100ng/ml. 2. The incidence of galactorrhea in hyperprolactinemic patients was 3.1 percent and the frequency of galactorrhea had direct relationship with the serum prolactin level and/or the frequency of abnormal menstrual pattern. 3. The incidence of pituitary tumor in hyperprolactinemic patients was 104 percent and sixty percent of patients with serum prolactin levels above 100ng/ml had a pituitary tumor . 4. There was an inverse correlation between serum prolactin and progesletone value. 5. The frequency of anovulatory menstrual cycle evidenced by basal body temperature is 23.9 percent in patients with serum prolactin levels ranged from $20{\sim}40ng/ml$, whereas 76.9 percent in patients with serum prolactin levels above 100ng/ml.

Background and objectives: Bacterial vaginosis (BV) is recognized as the most prevalent type of vaginal infection, impacting approximately 19-24% of women in their reproductive years. The recurrence rate of BV is significant, negatively impacting the well-being of affected women. This study aimed to compare the therapeutic effects of a polyherbal Unani formulation and metronidazole in treating bacterial vaginosis. Methodology: In this prospective patient blinded standard controlled trial, a total of 40 individuals with a clinical diagnosis of bacterial vaginosis were randomly assigned to receive either an active control treatment (n = 20) or a test drug (n = 20). In the test drug combination of Acacia catechu, Azadirachta indica and Quercus infectoria in tablet (1g) form in the dose of 2 tablets orally twice daily with water was administered for 3 weeks. In the active control standard drug, metronidazole 400 mg tablet, orally twice daily was given for one week. The primary outcome measure was clinical cure; H. negative Amsel's criteria and a reduction in subjective symptoms, while the secondary outcome measure was an improvement in SF-36 quality of life (QOL). Results and conclusion: Both the experimental treatment and the metronidazole demonstrated a significant clinical cure for bacterial vaginosis as well as an increase in health-related quality of life. Based on these findings, it appears that the test medication is a potent Unani formulation for the treatment of bacterial vaginosis. A well conducted trial with a bigger sample size is required to corroborate these findings.

Background Breast reconstruction refers to the rebuilding of a woman's breast using autologous tissue or prosthetic material to form a natural-looking breast. It is increasingly offered to women undergoing mastectomy for breast cancer. However, there is no systematic analysis available for the expanding area of research on breast reconstruction. Methods A bibliometric method was used to obtain a view of the scientific production about breast reconstruction by data extracted from the Institute for Scientific Information (ISI). Specific parameters were retrieved from the ISI. Articles about breast reconstruction were analyzed to obtain a view of the topic's structure, history, and document relationships using HistCite software. Trends in the most influential publications and authors were analyzed. Results The number of articles was constantly increasing. Most highly cited articles described the methods of flap construction in the surgery. Other highly cited articles discussed the psychological or emotional aspects of breast reconstruction, skin sparing mastectomy, and breast reconstruction in the irradiated breast. Conclusions This was the first breast reconstruction scientometric analysis, representing the characteristics of papers and the trends of scientific production. A constant increase in the number of breast reconstruction papers and also the increasing number of citations shows that there is an increasing interest in this area of medical science. It seems that most of the research in this field is focused on the technical aspects of surgery.

Purpose: To research the changes of Skin Resistance Variability(SRV) over the period of ovarian cycle of healthy young women with normal and regular menstrual cycles using Oriental Medical Diagnose Autonomic system-3000 (OMD-3000). Methods: We measured SRV of 15 women who were working at O O Oriental Hospital from July to Oct. 2008. Each woman took the OMD-3000 test 8 times during 2 menstrual cycles. Each cycle consists of 4 phases-follicular phase, ovulation, luteal phase and menstruation. We analyse the data by SPSS 12.0 for windows. the one-way ANOVA by Repeated Measure(p<0.05). Results: 1. (1) The Factor AA means at zone 1 were 0.77$\pm$0.40, at zone 2 were 1.07$\pm$0.68, at zone 3 were 0.77$\pm$0.35, at zone 4 were 0.68$\pm$0.32, at zone 5 were 0.74$\pm$0.29, at zone 6 were 0.85$\pm$0.30, and at zone 7 were 0.74$\pm$0.29. The Factor AA means were lower than normal range at zone 1,3,4,5,6 and 7. The graph pattern of M shape was caused by the Factor AA means at zone 2 and zone 6 were higher than others. (2) The Factor AA means at zone 1 and zone 3 show abnormal regulation state. 2. During the menstruation. the Factor AA means were higher at zone 1,2 and 3 than other zones. During the ovulation, the Factor AA means were higher at zone 4,5,6 and 7 than other zones. Especially at the menstruation phase in zone 2 and at the ovulation phase in zone 6 tend to be highest means than other phases respectively. 3. However there were no significant difference of means during 4 ovarian phases in 7 zones except ovulation phase to luteal phase at zone 4(p = 0.013). Conclusion: The results suggest that changes of SRV during 4 menstrual cycles are not variables in reading 7-zone-diagnostic system. Further study will be needed.

The purpose of this study was to construct and validate a middle - aged exercise adherence model. The model was designed based on self - determination theory. Participants were 215 middle-aged men and women aged 40-60 who had been exercising for more than six months. Data was collected from four big cities of Seoul, Busan, Gwangju and Daejeon in Korea, using a questionnaire consisting of basic psychological needs, intrinsic motivation, social support, and exercise adherence. Data were analyzed with SPSS 19.0 and AMOS 20.0. Social support and exercise adherence of the questionnaire were partially revised and verified by confirmatory factor analysis. The results of the study were as follows. The model's fit indices: GFI = .938, AGFI) = .915, NFI = .912, CFI = .941, and RMSEA = 0.041. The model satisfied the model fit of the structural model equation. This study model based on self - determination theory was confirmed that basic psychological needs, intrinsic motivation, and social support were important factors for the middle - aged's exercise adherence. Basic psychological need and intrinsic motivation had a direct influence on the adherence of exercise, and social support indirectly influenced the exercise adherence through intrinsic motivation. Both basic psychological needs and social support directly affected internal motivation. The most influential factor in the middle - aged's exercise adherence was intrinsic motivation. In conclusion, it was found that intrinsic motivation such as interest and fun is important for the middle - aged to continue the exercise. Also, the basic psychological needs were important for middle aged's exercise adherence. The results of this study will provide basic data for restoring or maintaining health by continuing exercise. Strategies that enhance intrinsic motivation are needed when a chronic ill person needs to continue long-term exercising.
