Abstract

The invention discloses a novel method for establishing a vascular dementia rat model. According to the novel method, a 6-week old male clean and healthy Sprague Dawley (SD) rat with the weight of 180-220g is subjected to long-term gavage by adopting isocarbophos, wherein the gavage concentration of the isocarbophos is 0.5mg / kg, the gavage capacity is 3ml / kg, the gavage frequency is one time every other day, and the gavage period is 24 weeks. The vascular dementia rat model is established through chronic damage of the isocarbophos to the brain vessels and brain nervous tissues of the SD rat.

Description

technical field [0001] The present invention relates to a novel method for establishing a rat model of vascular dementia, specifically a long-term gavage of SD rats with isocarbophos, and treatment of blood vessels and brain nerve tissues of SD rats with isocarbophos Cause chronic injury to establish a rat model of vascular dementia. Background technique [0002] VD (Vascular Dementia, VD) is a dementia syndrome caused by brain tissue damage caused by a series of vascular damage factors. A group of dementia syndromes mainly characterized by memory impairment and cognitive function decline, or accompanied by language function decline, emotion and personality disorders as the main clinical manifestations. [0003] In European and American countries, VD accounts for 15% of the total number of senile dementias; in China, Japan and other Asian countries, VD accounts for 50% of the total number of senile dementias. At present, the prevalence of VD in my country is 324 / 100,000, a...
