ABSTRACT
OBJECTIVE@#To establish a simple and reliable model of cervical vertigo in rats with hyperactivity of liver-yang syndrome, and to establish a simple and feasible method for evaluating the degree of vertigo in animals.@*METHODS@#SPF male SD rats (aged 8 weeks, weighing 280 to 320 g) were randomly divided into 4 groups (6 rats in each group). The model of cervical vertigo of hyperactivity of liver yang syndrome (joint modeling group) was established by combining local injection of lauromacrogol (hardener) and receiving decoction by gavage. The joint modeling group was compared with the hardener group, the decoction group and the blank control group. The vertigo degree of rats was measured by the time of passing through a glass tube (running time) before modeling, 2 weeks and 3 weeks after the established model.@*RESULTS@#There was no statistical difference in the running time between control group and decoction group, between joint modeling group and hardener group. The running time in the hardener group and the joint modeling group was longer than that in the control group (0.05).@*CONCLUSION@#This method can effectively establish a rat model of cervical vertigo with hyperactivity of liver-yang syndrome, and the running time can reflect the degree of vertigo in rats to a certain extent. This experiment provides a simple and feasible animal model and detection method for research of cervical vertigo in the future.
