[0098] Experimental example 3 Genipin anti-cerebral ischemia experimental research

[0099] The use of mice to make cerebral ischemia models is the most commonly used method for anti-ischemia research. Commonly used models include global cerebral ischemia, permanent focal cerebral ischemia and focal cerebral ischemia-reperfusion, each of which has its own characteristics. Angle mimics the pathogenesis of the acute phase of ischemic stroke. The present invention utilizes rat permanent cerebral ischemia model (pMCAO) to evaluate the curative effect of genipin anti-cerebral ischemia drug,

Abstract

The invention relates to application of genipin in prevention or treatment of ischemic brain injury. Brain injury is particularly related to injury of microglial cells or human umbilical vein endothelial cells. The invention further relates to a medicine composition containing genipin for preventing or treating ischemic brain injury.

Description

technical field [0001] The present invention relates to the use of genipin and the pharmaceutical composition containing it in the preparation of medicines for preventing and / or treating ischemic brain injury. Background technique [0002] Cerebrovascular disease is one of the three major diseases that lead to human death. Among them, ischemic cerebrovascular disease (ie, ischemic brain injury) is a common clinical critical disease, which refers to the local brain tissue including nerve cells, glial cells and other cells. Degeneration, necrosis or transient loss of function due to blood supply disorders account for about 80% of cerebrovascular diseases, and become a serious threat to human life and health due to its high morbidity, high mortality, high disability rate, and high recurrence rate. one of the main diseases. Ischemic brain injury is extremely harmful to the health of patients and often results in irreversible brain damage. Due to the interruption of cerebral ar...
