Xenoestrogens, phytoestrogens and synthetic estrogens, are able to bind to estrogen receptors, and to mimic estrogenic activities in a cell and tissue specific manner. For the characterization of environmental estrogens mainly mammary derived and yeast based models have been used. The aim of this
Purpose/Objective. To investigate the effect of Actaea racemosa (AR) extract on in vitro osteogenic differentiation of rat bone marrow mesenchymal stem cells (BMSCs) via the ER/NO/cGMP signaling pathway. Methods/Materials. Rat BMSCs were treated with osteogenic differentiation-inducing medium
OBJECTIVE
Some phytoestrogens are believed to have selective estrogen receptor modulator (SERM) activity with no action in the uterus but beneficial effects in the hypothalamo/pituitary unit and in the bone and are presently the focus of clinical interest. In the present experiments, the effects of
Estradiol (E2) and testosterone (T) effectively prevent orchidectomy (orx) induced osteoporosis. T, however, stimulates prostate proliferation which may lead to malignancy. We showed that a Cimicifuga racemosa (CR) preparation had bone-sparing effects without exerting estrogenic effects in the
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a well-known environmental contaminant that exerts its toxicity through a variety of signaling mechanisms. The present study evaluated the effects of 27-deoxyactein, one of the major constituents isolated from Cimicifuga racemosa, on TCDD-induced
In this prospective longitudinal clinical trial, 87 postmenopausal women receiving for 12 consecutive months a daily dose of 40 mg of a dry extract preparation of Cimicifuga racemosa (Klimadynon) for relief of vasomotor symptoms were followed up by evaluation of total hepatic blood flow, assessed by
Postmenopausal women treated with an isopropanolic extract of Cimicifuga racemosa underwent a decrease in the urinary concentration of N-telopeptides, a marker of bone resorption, and an increase in alkaline phosphatase, a marker of bone formation, at the third month of therapy. Serum from treated
OBJECTIVE
In this study, the effects of the Cimicifuga racemosa (CR) preparation CR BNO 1055 on markers of bone metabolism, hormones, sex hormone-binding globulin (SHBG), lipometabolism, vaginal maturity, and routine laboratory parameters were compared with those of conjugated estrogens (CE) and
An isopropanolic extract (iCR) from the rhizomes of Cimicifuga racemosa (black cohosh) is used an alternative in the treatment of menopausal symptoms, and animal studies suggest positive skeletal effects. iCR stimulated osteoblastic OPG protein secretion by 3- to 5-fold as early as 12 h without
OBJECTIVE
In the present study, therapeutic effects of the Cimicifuga racemosa preparation CR BNO 1055 (Klimadynon/Menofem) on climacteric complaints, bone metabolism and endometrium will be compared with those of conjugated estrogens (CE) and placebo. The question whether CR BNO 1055 contains
Eight botanical preparations that are commonly used for the treatment of menopausal symptoms were tested for estrogenic activity. Methanol extracts of red clover (Trifolium pratense L.), chasteberry (Vitex agnus-castus L.), and hops (Humulus lupulus L.) showed significant competitive binding to
Osteoporosis is a systemic skeletal disease characterized by low bone mass and microarchitectural deterioration of bone tissue, with a consequent increase in bone fragility and susceptibility to fracture. In order to improve the treatment of osteoporosis, identification of anabolic agents with
Symptoms associated with menopause can greatly affect the quality of life for women. Botanical dietary supplements have been viewed by the public as safe and effective despite a lack of evidence indicating a urgent necessity to standardize these supplements chemically and biologically. Seventeen
