Autonomic activity test,Miriam hole plate test and avoiding darkness test were measured with the indexes of autonomic activity times,Miriam hole plate times,incubation period and mistake times of avoiding darkness test to determine the nervous excitation and passive escaping ability of mice which were rared for 90 d with egg yolk lecithin(40%,50%,67%).
以含40%,50%,67%蛋黄卵磷脂的大豆色拉油分别经口灌胃昆明种小鼠,通过对受试小鼠进行自主活动、洞板和避暗试验,以自主活动次数、探洞次数和避暗试验的潜伏期和错误次数为衡量指标,评价蛋黄卵磷脂对小鼠的神经兴奋性和被动逃避能力的影响。
