摘　　要：BACKGROUND： The core symptoms of attention deficit, impulsiveness, hyperactivity of attention deficit hyperactivity disorders （ADHD） can concurrently present in spontaneous hypertensive rats. Neuropathological, biochemical and pharmacological studies also support it. Spontaneous hypertensive rats are one kind of best ADHD animal models, which has been accepted at present. Yizhining elixation can reinforce kidney and calm liver, strengthen spleen and nourish heart, benefit intelligence and focus attention, but its therapeutic effect on treatment of ADHD needs to be further investigated. OBJECTIVE： To observe the effect of Yizhining elixation on the persistent active attention deficit and impulsiveness of rats with spontaneous hypertension. DESIGN： Observational and controlled analysis. SETTING： Department of Pediatrics, the First Affiliated Hospital of Guangzhou University of Chinese Medicine. MATERIALS： Thirty-six male rats with spontaneous hypertension, of clean grade, were involved in this experiment. The involved rats were provided by Shanghai SLAC Laboratory Animal Co., Ltd., and they did not undergo any experiments; Yizhining elixation was composed by Guiban, Shenglonggu, Yuanzhi, Shichangpu, Yejiaoteng, Shudi, Dangshen, Yunling, Fuxiaomai, Wueizi. etc. Crude drug, provided by Outpatient Dispensary, Affiliated Hospital of Guangzhou University of Chinese Medicine, was prepared into water elixation, which contained crude drug of 1.154 g/mL. METHODS： This experiment was carried out in the Department of Pediatrics, First Affiliated Hospital of Guangzhou University of Chinese Medicine between March and July 2005. The involved rats were randomized into 3 groups： Yizhining high dose group, Yizhining low dose group and blank control group, with 12 rats in each. Changes in sustained attention and impulsiveness of rats were detected before and after administration of Yizhining elixation by ＂5-choice serial response time task＂ method. Following above-mentioned training and detection, rats in each BACKGROUND： The core symptoms of attention deficit, impulsiveness, hyperactivity of attention deficit hyperactivity disorders （ADHD） can concurrently present in spontaneous hypertensive rats.
