Embodiment 1

[0021] [Example 1] The proliferation effect of catalpol on isolated ovarian granulosa cells (MTT method)

[0022] Female rats aged 22-27 days were killed by cervical dislocation after 48 hours of routine feeding. The bilateral ovaries of the rats were aseptically removed, and the ovaries were crushed to release granulosa cells. They were treated with 2 mL of DMEM-F12 containing penicillin and streptomycin. Dilute in culture medium and gently pipette to disperse into single cells. Pellet cells were collected by centrifugation. A certain concentration of cell suspension was inoculated in a 24-well plate, 80 μl per well, and 120 μl of culture medium was added to each well to adjust the cell density to 200 μl / well, and 6 parallel wells were set up for each group. Put it in 5% CO 2 Cultivate in the incubator for 24h. Take CO 2 The granule cell suspension was cultivated in the incubator for 24 hours, and each well was successively added with cadmium chloride at the modeling conc...

Embodiment 2

[0026] [Example 2] The effect of catalpol on the estrogen and progesterone secretion of isolated ovarian granulosa cells (radioimmunization method)

[0027]Female rats aged 22-27 days were killed by cervical dislocation after 48 hours of routine feeding. The bilateral ovaries of the rats were aseptically removed, and the ovaries were broken to release granulosa cells. They were treated with 2ml of DMEM-F12 containing penicillin and streptomycin. Dilute in culture medium and gently pipette to disperse into single cells. Pellet cells were collected by centrifugation. A certain concentration of cell suspension was inoculated in a 24-well plate, 80 μl per well, and 120 μl of culture medium was added to each well to adjust the cell density to 200 μl / well, and 6 parallel wells were set up for each group. Put it in 5% CO 2 Cultivate in the incubator for 24h. Take CO 2 The granule cell suspension was cultivated in the incubator for 24 hours, each hole was added with cadmium chlori...

Embodiment 3

[0031] [Example 3] Effect of catalpol on the secretion of estrogen and progesterone in natural aging rats (radioimmunization method)

[0032] Adopt the pre-aging model of natural aging. Select 14-month-old female SD rats with a body weight of (270±30) g. After the animals are fed for one week, do vaginal cytology smears and observe 4 estrous cycles continuously. Vaginal cytology shows that the estrous cycle is prolonged and then continues to be in estrus , Repeated pseudo-pregnancy cell phase, as a successful model of female aging. The natural aging rats were randomly divided into model group, catalpol (1mg / kg, 3mg / kg, 5mg / kg) group and positive drug group, with 10 rats in each group, and another 11 female rats aged 4 months were taken as normal The control group was intragastrically administered once a day, and the normal control group and the model group were given equal volumes of normal saline. After 30 days of continuous administration, blood was collected from the orbit...

Abstract

The invention discloses an application of catalpol in preparing ovarian aging resisting medicaments. The catalpol can treat various ovarian aging diseases, and particularly has obvious effects on polycystic ovarian syndrome, dysfunctional uterine bleeding, premature ovarian failure or menopause syndrome and the like. According to the application, the catalpol is prepared into oral medicaments, transdermal medicaments or injections for treating ovarian failure diseases.

Description

technical field [0001] The invention relates to the medical use of catalpol, that is, the application of catalpol in drugs for effectively treating various ovarian recession diseases. Background technique [0002] Ovarian aging is a complex biological process with multiple factors interacting and gradually accumulating. The main cause of ovarian aging is the decline in the number of follicles as the number of follicles passes by. The accumulation of metabolites in the body changes the microenvironment of the ovary, such as damage to follicles by free radicals and end products of glycation, and mitochondrial DNA mutations, With the continuous accumulation of factors such as telomere shortening, the quality of remaining follicles is also reduced; the expression and function of a series of genes in the ovary are changed, and the secretion of H-P-O axis (Hypothalamus-Pituitary-Ovary Axis, hypothalamus-pituitary-ovary axis) hormones Finely regulate ovarian function. The decline...
