Abstract

The invention discloses application of nifedipine to preparation of medicine for preventing brain blood vessel injury caused by zero gravity. The nifedipine can realize differential regulation and control on the function of brain and mesenteric small artery of simulated zero gravity rats through the inhibition effects on L type Ca<2+> channels, i.e., the nifedipine can recover the function of the brain artery blood vessels of the simulated zero gravity rats through inhibiting the L type Ca<2+> channels of smooth muscle cells of the brain artery blood vessels; and the nifedipine does not have the obvious influence on the function of the mesenteric small artery blood vessels and the L type Ca<2+> channels of smooth muscle cells of the simulated zero gravity rats.

Description

Technical field [0001] The invention belongs to the technical field of prevention and treatment of cerebrovascular remodeling caused by weightlessness and other environments, and relates to the application of nifedipine to prevent and treat cerebrovascular damage. Background technique [0002] Space activities are a special activity. During space activities, the human body is in a weightless / microgravity environment. In this case, the blood in the human body that has adapted to the 1G gravity on the earth’s surface will undergo a head shift and this A series of physiological and psychological problems have an impact on the physical health and work efficiency of the astronauts, and when the spaceflight activities are over and the astronauts return to the 1G gravity environment on the earth's surface, their cardiovascular function will experience obvious dysfunction Phenomenon, such as poor standing endurance and decreased exercise endurance. The longer the period of stagnation in...
