同一种类实验动物不同品种，性别、年龄的正常生理生化参数不同。以往报道健康大白鼠生理生化参数，如胆红素、胆固醇、钾、钠、钙、镁等正常值，大多以Wlstar品种大白鼠为蓝本。而目前动物实验已趋了用SD大白鼠，但对其生理生化参数报道较少，微量元素如铁、锌的资料更少。B前 The same type of experimental animals of different breeds, sex, age, the normal physiological and biochemical parameters are different. Previous reports of physiological and biochemical parameters of healthy rats, such as bilirubin, cholesterol, potassium, sodium, calcium, magnesium and other normal values, mostly based on the Wlstar species of rats modeled. At present, animal experiments have been used SD rats, but its physiological and biochemical parameters reported less, less trace elements such as iron, zinc less information. B ago
