Objective: To evaluate the effect of Ephedra Sinica and Evodia Rutaecarpa on resting metabolic rate(RMR), weight and body composition in obese women during low-calorie diet. Methods: We recruited 90 healthy premenopausal women$(body\;mass\;index{\geq}25kg/m^2)$ and randomly assigned to three groups(ephedra group, evodia group and placebo group). Subjects were administered Ephedra Sinica(6g twice a day) or Evodia Rutaecarpa(6g twice a day) or placebo in a double-blind fashion and participated in low-calorie diet for 8 weeks. Resting metabolic rate and body composition were measured at baseline, 4 and 8 weeks. Results: RMR change for 4 weeks was significantly higher in the ephedra group compared with the placebo group(p<.05). But the change for 8 weeks was not significant and the Evodia group showed no significant RMR change. Weight and percent body fat changes for 4 weeks and 8 weeks were significantly higher than the placebo group in the ephedra group(p<.05), but the Evodia group didn't show significant level. Conclusions: This study supports and emphasizes the benefits of herbal medicine in maintaining or increasing RMR during low-calorie diet. Especially Ephedra treatment was effective on significant maintainment of RMR, loss of weight and percent body fat(P<.05).

Pseudoangiomatous stromal hyperplasia (PASH) was initially described by Vuitch et al. as a benign breast lesion, consisting of mammary stromal proliferations which simulate vascular lesions, and which might be mistaken for a low-grade angiosarcoma. This condition occasionally presents as a palpable mass in postmenopausal women, but is more frequently encountered as an incidental component in premenopausal women. Clinical, radiological, and fine-needle aspiration (FNA) findings associated with this condition can mimic those observed in conjunction with a phyllodes tumor or a fibroadenoma. The cytological features of PASH are generally nonspecific, and its diagnosis by FNA cytology is fairly difficult. In this study, we report a case on PASH, manifesting as a palpable mass.

We performed case-control study to evaluate relationship between food intake and risk of breast cancer. We interviewed breast cancer cases(n=108) who were newly histologically identified and selected from Hanyang and Soonchunhyang University Hospital in Seoul. We used hospital-based control subjects(n=121), who were selected from the patients in the department of plastic surgery, general surgery and opthalmology of the same hospital by frequency matching. Matching variables were age($\pm$4 age) and menopausal status. We collected information on general characteristics of subjects, history of disease, family history of breast cancer, vitamin supplementation, alcohol intake, and food intake through individual interview. Dietary information was ascertained via a food frequency questionnaire method(total item=98). All analyses was conducted according to menopausal status. Especially, pepper and grape intake in premenopausal women, showed protective effect in breast cancer. Otherwise consumption of meat, pork, and fish was not associated with breast cancer risk in this study. At milk and dairy products, milk intake was associated with lower risk of breast cancer in postmenopausal women and overall intake of soy products was associated with breast cancer risk, but not significant. These findings suggested that consumption of some fruit and vegetable intake was a protective factor on breast cancer and further study with more number of subjects should be need to evaluate the breast cancer risk.

Objectives: To evaluate the frequency of cytohistologic discrepancy of high-grade squamous intraepithelial lesions (HSILs) in Pap smears and associated factors. Methods: Medical records of 223 women with HSIL Pap smears who were treated at Thammasat University Hospital were reviewed. Data on age, parity, menopausal status, contraceptive use and colposcopic directed biopsy and loop electrosurgical excision procedure (LEEP) pathology results were recorded. Results: Mean (SD) age of patients was 38.0 (9.4) years. The majority were premenopausal (86.5%) and multiparous (83.9%). Cytohistologic discrepancy between the Pap test and colposcopic-directed biopsy histology was 45.7% and that between the Pap test and LEEP histology was 29.5%. Fifty-four (24.2%) women had no high-grade CIN on both colposcopic directed biopsy and LEEP. Nulliparity, postmenopausal status and having no oral contraceptive pills use were factors associated with cytohistologic discrepancy. Conclusion: The exact cytohistologic discrepancy rate was relatively high (24.2%). Factors associated with cytohistologic discrepancy were nulliparity and postmenopausal status and having no oral contraceptive pill use.

Objectives: Hormonal changes during menopause alter a woman's susceptibility to some disorders. Information regarding the prevalence of temporomandibular disorder (TMD) in menopausal women is limited in the literature. In this study, the prevalence and severity of TMDs were compared between menopausal and non-menopausal women. Materials and Methods: The study included 140 women (69 premenopausal and 71 postmenopausal) 45 to 55 years of age that were examined in Shiraz Dental School, Shiraz in Iran. The Helkimo clinical dysfunction index (Di) was used to evaluate temporomandibular joint (TMJ) dysfunction. The data were analyzed using chi-square and Fisher's exact tests. Results: Occurrence of TMD was significantly higher in menopausal than non-menopausal women (P<0.001). All the TMD criteria based on Helkimo Di except range of mandibular movement were significantly more common in menopausal women. The range of mandibular movement was not significantly different between menopausal and non-menopausal women (P=0.178). Conclusion: The results from this study show that TMD can be considered more common and severe in menopausal than non-menopausal women. This finding indicates that, similar to other conditions in menopausal women such as arthritis and osteoporosis, TMD should be taken into consideration by dental and medical professionals.

The glycemic index (GI) and glycemic load (GL) have been considered risk factors for breast cancer, but association studies of breast cancer risk using simple GI and GL might be affected by confounding effects of the overall diet. A total of 357 cases and 357 age-matched controls were enrolled, and dietary intake was assessed using a validated food frequency questionnaire (FFQ) with 103 food items. GI and GL dietary patterns were derived by reduced rank regression (RRR) method. The GI and GL pattern scores were positively associated with breast cancer risk among postmenopausal women [OR (95%CI): 3.31 (1.06-10.39), p for trend=0.031; 9.24 (2.93-29.14), p for trend<0.001, respectively], while the GI pattern showed no statistically significant effects on breast cancer risk, and the GL pattern was only marginally significant, among premenopausal women (p for trend=0.043). The GI and GL pattern scores were positively associated with the risk of breast cancer in subgroups defined by hormone receptor status in postmenopausal women. The GI and GL patterns based on all food items consumed were positively associated with breast cancer.

The mechanisms by which iron is absorbed are similar to those of divalent metals, particularly manganese, lead, and cadmium. These metals, however, show different toxicokinetics in relation to menarche or menopause, although their interaction with iron is the same. This review focuses on the kinetics of these three toxic metals (manganese, lead, and cadmium) in relation to menarche, pregnancy, and menopause. The iron-manganese interaction is the major factor determining sex-specific differences in blood manganese levels throughout the whole life cycle. The effects of estrogen overshadow the association between iron deficiency and increased blood lead concentrations, explaining why women, despite having lower ferritin concentrations, have lower blood lead concentrations than men. Iron deficiency is associated with elevated cadmium levels in premenopausal women, but not in postmenopausal women or men; these findings indicate that sex-specific differences in cadmium levels at older ages are not due to iron-cadmium interactions, and that further studies are required to identify the source of these differences. In summary, the potential causes of sex-specific differences in the blood levels of manganese, lead, and cadmium differ from each other, although all these three metals are associated with iron deficiency. Therefore, other factors such as estrogen effects, or absorption rate as well as iron deficiency, should be considered when addressing environmental exposure to toxic metals and sex-specific differences in the blood levels of these metals.

A vitamin B-6 (B-6) intake higher than the current Recommended Dietary Allowance (RDA) has been found to provide an improvement in immune system. Seven premenopausal women consumed their usual diet with the exception of foods relatively high in vitamin B-6 for a total of 27 d. After 7 d, all subjects received a multivitamin supplement containing 2mg B-6 and 4 subjects were given an additional 50mg of B-6 supplement for 20 d. Lymphocyte response to phytohemagglutinin (PHA) was measured before and after the supplementation. To determine the effect of different forms of B-6 on lymphocyte proliferation, cell culture media supplemented with pyridoxal (PL) and PLP, as well as B-6 free media, were tested. A 50mg B-6 supplement significantly increased vitamin B-6 status. There was no further enhancement on lymphocyte proliferation when subjects were taking an additional 50mg of vitamin B-6 supplement. In general, lymphocyte proliferation in media with either PLP or PL did not show any prominent difference. These [m-dings suggest that there may be no further benefits of a B-6 dose beyond twice that of the current RDA on lymphocyte proliferation. Further studies are necessary to examine the effect of the B-6 intake level on activities of enzymes involved in cellular B-6 metabolism in lymphocytes to provide substantial insight into the mechanisms underlying the role of B-6 in the lymphocyte proliferation.

Purpose: To investigate factors influencing the evaluation of background parenchymal enhancement (BPE) at follow-up breast magnetic resonance imaging (MRI) after adjuvant endocrine therapy. Materials and Methods: One hundred twelve women with breast cancer and MRI of the contralateral unaffected breast before and after endocrine therapy were identified. Two readers in consensus performed blinded side-by-side comparison of BPE (minimal, mild, moderate, and marked) before and after therapy with categorical scales. Age, body mass index, menopausal status, treatment regimen (selective estrogen receptor modulator or aromatase inhibitor), chemotherapy, follow-up duration, BPE at baseline MRI, MRI field strength before and after therapy, and recurrence were analyzed for their influences on decreased BPE. Results: Younger age, premenopausal status, treatment with selective estrogen receptor modulator, MRI field strength, and moderate or marked baseline BPE were significantly associated with decreased BPE. In multivariate analysis, MRI field strength and baseline BPE showed a significant association. Conclusion: MRI field strength and baseline BPE before and after therapy .were associated with decreased BPE at post-therapy, follow-up MRI.

Menopause, the cessation of menstruation caused by the decline in estrogen production, occurs in 95% of women between 40 and 60 years. Sleep disturbance is a frequent complaint during the perimenopause period. In contrast to premenopausla women, menopausal women experience more reduction in the total sleep hours and report more sleep disturbances, such as insomnia, noctiria and sleep disordered breathing. But the prevalence, etiology and treatment of sleep disturbances in menopause are still controversal. So further investigations are required to elucidate the factors that account for the differences in sleep disturbance between premenopausal and postmenopausal women. There are suggestive data that estrogen and progesterone deficiency may increase the susceptibility for sleep disorder in menopause. Furthermore, there are suggestive evidence from observational studies and a limited number of randomized, controlled trials that hormone replacement therapy after menopause improves sleep. However, the clinical relevance of hormone replacement therapy is unproved. So the overall benefit of hormonal replacement in postmenopausal women with sleep related disorders should be individualized to avoid potential side effects. Several studies evaluated the role of melatonin, because this hormone has effects on core body temperature & insomnia. But the exact dosage and the effects of long-term use of melatonin are unclear. So, caution is indicated in melatonin administration.
