Embodiment 1
[0050] TQW's estrogen-like effect in vivo experimental research adopts three classic animal models recognized internationally for the study of estrogen effects: immature mice, ovariectomized mice, and aging rat models respectively simulate the three physiological stages of low estrogen in women's life.
[0051] 1. Effect of TQW on target organs of immature mice
[0052] The immature mice are just weaned mice at 21 days after birth. At this time, the mice have not yet reached sexual maturity and body maturity. Drugs with estrogen-like effects can promote the development and maturity of their reproductive system.
[0053] 1 Materials and methods
[0054] 1.1 Materials
[0055] KM mice, ♀, 21 days old, were purchased from the GLP Center of Heilongjiang University of Traditional Chinese Medicine.
[0056] TQW suspension: suspend TQW in distilled water, and the ig dose is 15 mg / kg.
[0057] Nilestriol suspension (Nilestrdiol): nilestriol (purchased from Hualian Pharmaceutical Fa...
Embodiment 2
[0163] MCF-7 cells are ER-positive human breast cancer cell lines, which can be specifically regulated by estrogen or estrogen-like active substances to proliferate. The MCF-7 cell estrogen-like proliferation assay is very sensitive, simple and easy to perform, and is widely used in the rapid screening and evaluation of phytoestrogens.
[0164] 1 method
[0165] 1.1 The effect of TQW on the proliferation of MCF-7
[0166] 1.1.1 Cell culture
[0167] MCF-7 cells were cultured in DMEM high-glucose solution containing 10% fetal bovine serum at 37°C, 5% CO 2 , the relative saturation humidity.
[0168] 1.1.2 MTT cell proliferation assay
[0169] Two days before the start of the experiment, the cells were washed twice with PBS, and then cultured in phenol red-free DMEM (containing 5% CD-FBS) to deplete the estrogen stored in the cells. Select the cells in the logarithmic growth phase, digest the cells with 0.25% trypsin, and divide 2×10 3 cells / well were inoculated on a 96-we...
Embodiment 3
[0179] To observe the effect of TQW on the related symptoms of perimenopausal syndrome such as hot flashes, insomnia and hyperlipidemia.
[0180] 1. Effect of TQW on adrenal weight and rectal temperature of ovariectomized mice
[0181] Using ovariectomized mouse experiments, ovariectomy can rapidly reduce the level of estrogen in the body, which can simulate the physiological and pathological characteristics of postmenopausal women.
[0182] 1 Materials and methods
[0183] 1.1 Materials
[0184] KM mice, ♀, 12 weeks old, non-pregnant, were purchased from the GLP Center of Heilongjiang University of Traditional Chinese Medicine.
[0185] TQW suspension: suspend TQW in distilled water, and the ig dose is 15 mg / kg.
[0186] Nilestriol suspension (Nilestrdiol): nilestriol (purchased from Hualian Pharmaceutical Factory of Shanghai Pharmaceutical Group, National Drug Approval: H3102164), suspended in distilled water, ig 0.5 mg / kg.
