目的 :对脑蛋白水解物进行一般药理学研究。　方法 :按常规药理学研究方法观察脑蛋白水解物对动物精神活动、神经系统、心血管系统、呼吸系统的影响。　结果 :在小鼠腹腔和大鼠静脉注射人临床等效剂量的脑蛋白水解物后 ,动物的精神、神经系统、心血管系统均无影响。　结论 :脑蛋白水解物对动物无任何毒副作用。 OBJECTIVE: To conduct a general pharmacological study of brain protein hydrolysates. Methods: The effects of brain protein hydrolyzate on animal mental activity, nervous system, cardiovascular system and respiratory system were observed by routine pharmacological methods. Results: There was no effect on the spirits, nervous system and cardiovascular system of animals after intraperitoneal injection of clinically equivalent dose of brain proteolysate in mice’s abdominal cavity and in rats. Conclusion: Brain protein hydrolyzate has no side effects on animals.
