Problems solved by technology

[0005] Xinyue Capsules, which mainly contain total saponins from stems and leaves of American ginseng, have been clinically used for more than 20 years. At present, there is no research on the application of total saponins from stems and leaves of American ginseng to combat bone loss caused by weightlessness / simulated weightlessness.

Embodiment 1

[0020] The main component of the total saponins of American ginseng stems and leaves used in the present invention is Xinyue Capsules (National Drug License No. Z20030073), which is used in clinical practice.

[0021] 1. Effects of total saponins from American ginseng stems and leaves on the body weight of mice with bone loss induced by simulated weightlessness.

[0022] 1.1 Animals and experimental drugs

[0023] Fifty healthy male C57BL / 6 mice were selected; they were reared in separate cages in a breeding room with natural light and artificial light in an environment with a temperature of 22°C-26°C and an air humidity of 45%-65%. Drinking water; adaptive feeding for one week. The experimental drug American ginseng stem and leaf total saponin (99.0% purity) was provided by Ji'an Yisheng Pharmaceutical Co., Ltd., Jilin Province.

Abstract

The invention discloses an application of panax quinquefolius stem and leaf total saponins in preparation of a composition for resisting bone loss. The beneficial effects of the invention are as follows: according to the application of the panax quinquefolius stem and leaf total saponins in preparation of the composition for resisting bone loss, simulation experiments show that the panax quinquefolius stem and leaf total saponins can relieve mouse bone loss caused by simulated weightlessness, that is, it shows that the panax quinquefolius stem and leaf total saponins can effectively resist bone loss caused by special environments such as spaceflight.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to the application of total saponins from stems and leaves of American ginseng in the preparation of a composition for combating bone loss. Background technique [0002] During long-term space flight, bone loss occurs as a result of the combined effects of increased bone resorption and decreased bone formation. In microgravity, the rate of bone loss is more than 10 times the monthly loss of bone density in postmenopausal women on the ground. Bone density lost during a 6-month space flight is largely restored about 1,000 days after returning to the ground. However, the structural changes are irreversible, similar to those that occur in senile osteoporosis. In a series of adaptive changes in the human body in the microgravity environment, most of the system changes are self-limiting, and only the changes in the skeletal system show a progressive process. The detection of the bo...
