Objectives: The aim of this study was to assess the duration of lochia in women hospitalized at Korean medical postpartum care center and to identify factors that influence duration of lochia. Methods: On the obstetric variables of 315 cases, the duration of lochia was analyzed. In the postpartum care center, the obstetric variables were asked of 315 cases of women, and who examined a body composition. After discharge, women were surveyed for the duration of lochia by telephone. Results: The median duration of lochia was 30 days and the range was 18~53 days. Maternal age, parity and mode of delivery were associated with its duration. So, its duration was longer on women over the age of 35, multipara and women had a Cesarean section. Its duration was correlated with gestational age and BMI before pregnancy, but not neonatal gender, birth weight, maternal BMI change during pregnancy, maternal body weight gain, BMI before delivery. Conclusions: It was 30 days that the median duration of lochia of women who had been got Korean medical postpartum care management, and which was slightly different from previous studies. And it was influenced by maternal age, parity, mood of delivery, gestational age and BMI before pregnancy. In future more studies or surveys for the duration of lochia of women with no treatment, lochial pattern and so on should be done.

Objectives: Breast cancer is the most common cancer among women and has rapidly increasing rate annually. At present, western cancer therapies by surgery, radiation, and anticancer drug have not been fully effective. So many interests are given to herbal medicine on cancer treatment recently. This study was designed to investigate the effects of Curcuma longa L. (CL) on MDA-MB-231 human breast cancer cells and DMBA-induced breast cancer in rats. Methods: In this experiment, MDA-MB-231 cells were cultured in cell culture plates. 0.0625, 0.125, 0.25, 0.5, 1.0 mg/ml of CL extract were tested for their anti-proliferative effects on MDA-MB-231 cells by MMT assay. And we induced breast cancer in rats. The changes in tumor's weight, and the effects on proliferations of splenocyte and thymocyte were investigated. Results: CL showed anti-proliferative effects on MDA-MB-231 cells in proportion to concentration of the CL. DMBA-induced breast cancer in rats, tumor's weight of the rat was not statistically significant, but showed a tendency to be reduced in the groups treated with CL. Proliferation rate of the rat's splenocyte and thymocyte increased in proportion to CL. In breast cancer tissue, expression of ER-${\alpha}$ was weakened proportionately to the concentration of the CL. Conclusions: These data suggest that CL can prevent the proliferation of breast cancer, then CL is useful to treat patient with breast cancer.

Objectives: Osteoporosis is characterized by bone loss and morbidity with osteoporotic fracture. In this study, the author aimed to evaluate the effect of dried roots of Rehmannia glutinosa extract (RGE) on osteoblast proliferation in murine calvarial cells. Methods: The osteoblast separated from murine calvariae was cultivated for 6 days and evaluated the cell function. After the addition of RGE on the culture medium, we determined the effect of RGE on the cell viability, cell proliferation, protein synthesis, alkaline phosphatase activity, collagen synthesis and calcified nodule formation of the cultivated osteoblast. Results: The results were summarized as follows. 1. RGE did not change the survival rate of rat calvarial osteoblast. 2. RGE increased the proliferation of rat calvarial osteoblast. 3. RGE increased ALP activity of rat calvarial osteoblast., 4. RGE slightly affected protein synthesis of rat calvarial osteoblast. 5. RGE increased collagen synthesis of rat calvarial osteoblast. 6. RGE slightly affected calcified nodule formation of rat calvarial osteoblast. Conclusions: From these results, it is concluded that RG might improve the osteoporosis resulted from augmentation of osteoblast proliferation.

Purpose: The purpose of this study is to find out the patterns of teenage girls who is easy to suffer from dysmenorrhea with the Inbody test results by Sasang constitutions. Methods: The data from the 1681 participants were collected using a structured menstrual history questionnaire. Based on the survey responses, we had 97 adolescents with menstrual disorder as the test group and 97 adolescents without menstrual disorder as the control group. The clinical trials subjects were asked to respond to another questionnaire for identifying their constitutional types and undergo Inbody test. Results: The result of a comparison of the test and control groups showed that there' no relevance to the body fat mass and body fat percentage with menstrual irregularities. The lesser yang person with menstrual irregularities was no relevance to the body fat percentage. The greater yin person with menstrual irregularities was especially lacking in body fat mass and body fat percentage. The lesser yin person with menstrual irregularities was poor in body fat mass. Conclusions: As for study, female high school students with menstrual disorders have nothing to do with muscle mass. Body fats shortage could pose problems. According to the study, Taeumin female high school students usually needed to higher body fat than a general standard. It seems to be needed more body fat and weight than modern standards in period of poor sexuality for having a normal menorrhea especially Taeumin. It will take some continuing study that BMI standards should be changed or not on the Sasang constitutions.

Purpose: This review is to figure out evidence that suggest effectiveness of Korean Medicine treatments against cervical dysplasia. Methods: Studies on cervical cancer and cervical dysplasia were searched through 6 databases: Korean Studies Information Service System(KISS), National Discovery for Science Leaders (NDSL), Korea Institute of Science and Technology Information (Korean TK), Oriental Medicine Advanced Searching Integrated System (OASIS), the Journal of Korean Medicine, and the Journal of Korean Obstetrics & Gynecology. After that, the articles were extracted with reference point of Korean Traditional Medicine. Results: 37 articles were included lastly according to selection criteria. 3 of them were case reports on cervical dysplasia, and 34 were in-vitro studies on Human Papilloma Virus (HPV) positive cancer cell. In case reports, acupuncture, moxibustion, medical herbs and pharmacoacupuncture were used for treatments of cervical dysplasia with about 3 months. Experimental studies on cervical cancer cell showed that several herbs function with clear heat, eliminate stasis (淸熱解毒, 化瘀消腫) have anti-cancer effects inducing apoptosis. Conclusions: The results of articles are not enough to use in practice. Therefore, we indicates more advanced research methodology as follows: development of Korean Medicine treatment protocol with oral and external, in-vivo experimental study, and evaluation immunity index.

Objectives: We took breast milk samples and analyzed them using HPLC and LC/MS/MS, to evaluate the effects of taking Saenghwa-tang during breastfeeding on breast milk. Methods: The study participants were 20 lactating women who admitted in Korean medical postpartum care center. Breast milks were collected from paticipants who have been administrated Saenghwa-tang for more than 3 days. We used HPLC and LC/MS/MS for the determinations of amygdalin, liquiritins, 6-gingerol, decursin and decursinol angelate in Saenghwa-tang. Results: 1. Participants' $Mean{\pm}S.D$ (standard deviation) of age is $31.05{\pm}1.96$, and 15 participants had normal delivery and 5 participants had cesarean delivery. 12 participants were primipara and 8 participants were multipara. $Mean{\pm}S.D$ of lactating date is $9.4{\pm}0.94$. 2. Using HPLC, we learned LOQ level peak that matches the peak retention time of standard components of Saenghwa-tang was not detected from 20 breast milk samples. 3. Using LC/MS/MS, decursin of Angelicae Gigantis Radix was detected from HMSP 02, HMSP 04, HMSP 06, HMSP 11, and the each concentrations are 16, 2, 64, 11 ppb. Liquiritin of Glycyrrhizae Radix was not detected from HMSP 13~HMSP 18. Conclusions: Data obtained by this approach shows that this method is reliable and suitable for determining the safety of taking Saenghwa-tang during breastfeeding.

Objectives: The present study was carried out to investigate the effects of YJT on experimental hypothyroidism induced by sodium perchlorate and methimazolein in mice. Methods: 30 one-month-old C57BL6 mice were decided into 4 groups: 1) normal (n=6), 2) sodium perchlorate and methimazolein-induced hypothyroidism control (n=8), 3) hypothyroidism mice treated with low YJT (n=8), 4) hypothyroidism mice treated with high YJT (n=8). Sodium perchlorate and methimazolein were administered for 4 weeks, YJT (low and high) was administered for 2 weeks after sodium perchlorate and methimazolein were initiated for a total duration of 2 week. The changes were observed : weight of body, T3, T4, TSH, follicular cells in the thyroid tissues, LDL cholesterol, HDL cholesterol, triglyceride and free fatty acid, FBG, AST, ALT and so on. Results: YJT did not affect body weight gain. YJT restored free T4 level decreased by sodium perchlorate and methimazolein and prevented shrinking of follicles and proliferation of follicular cells in the thyroid tissues. In addition, YJT lowered total and LDL cholesterol levels elevated by sodium perchlorate and methimazolein respectively and ameliorated distribution of fat in liver tissues. In addition, the effect on fasting blood glucose (FBG), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were also investigated. Conclusions: These data suggest that YJT can be used to treat woman patients which are accompanied with hypothyroidism relatively safely.
