Abstract

The invention relates to an application of a vitamin E compound in preparation of a medicine for reducing the oxidative stress level caused by an anti-tumor medicine, an application of the vitamin E compound and the anti-tumor medicine in preparation of a medicine for improving immunity and an application of the vitamin E compound in preparation of a medicine for relieving myelosuppression caused by the anti-tumor medicine or relieving hemolysis diseases caused by the anti-tumor medicine.

Description

technical field [0001] The present invention relates to the use of vitamin E compounds in the preparation of medicines for down-regulating the level of oxidative stress caused by medicines, the use of vitamin E compounds in the preparation of medicines for improving immunity, and the preparation of medicines for alleviating myelosuppression or hemolysis. Uses in medicine. Background technique [0002] Many chemotherapeutic drugs have been proved to have strong anti-tumor activity in clinic. However, obvious toxic and side effects often appear during the treatment, which seriously restricts its clinical application. [0003] Reactive oxygen species (ROS) are highly reactive ions and free radicals, including singlet oxygen, superoxide radicals, hydroxyl radicals, and peroxides, which play imperative roles in many physiological processes. At lower concentrations, ROS serve as important second messengers regulating cell signaling, adhesion, migration, and homeostasis. High le...
