Embodiment

[0015] (1) Drugs and drug doses

[0016] Cinnamic acid: 6mg / kg, 12mg / kg, 24mg / kg, its purity detected by liquid chromatography is 98.12%. Positive drug: Cyclophosphamide 120mg / kg, purchased from Qilu Pharmaceutical Co., Ltd. (batch number: 20150203).

[0017] (2) Modeling and methods

[0018] Take 50 SPF mice, half male and half male, weighing 20±2g, and divide them into 5 groups, 10 mice in each group.

[0019] Among them, ① the blank group was administered intragastrically with the same volume of normal saline (0.2mL / 10g);

[0020] ②For the model group, the same volume of normal saline (0.2mL / 10g) was intragastrically administered;

[0021] ③High dose group of cinnamic acid;

[0022] ④ The middle dose group of cinnamic acid;

[0023] ⑤ Low-dose cinnamic acid group.

[0024] Intragastric administration, administration once a day, continuous administration for 10d. From the 6th day after the first administration, except the blank group, the mice in each group were intra...

Abstract

The invention discloses an application of cinnamic acid in preparation of drugs for treating myelosuppression caused by an antitumor drug. The antitumor drug is cyclophosphamide. The content of cinnamic acid in the drug is 6-24 mg / kg. The cinnamic acid is applied to myelosuppression caused by the antitumor drug cyclophosphamide for the first time. Results show that the cinnamic acid can increase the number of leukocytes and platelets in peripheral blood of mice, and reduce peripheral hemogram decline caused by cyclophosphamide; and the number of karyocytes in mouse bone marrow can be increased. The cinnamic acid is proved to have a protective effect on cyclophosphamide induced myelosuppression, and a new thought is provided for prevention and treatment of myelosuppression caused by antitumor drugs.

Description

technical field [0001] The invention relates to the technical field of medicine preparation, in particular to the application of cinnamic acid in the preparation of drugs for treating myelosuppression caused by cyclophosphamide. Background technique [0002] Chemotherapy is still one of the main means of treating malignant tumors. Most chemotherapeutic drugs are poorly selected in clinical practice. While destroying tumor cells, they also cause severe toxic effects on normal cells that are vigorously dividing and proliferating in the body. Myelosuppression is the most common one of the adverse reactions. [0003] Cyclophosphamide is used as an antineoplastic agent for malignant lymphoma, multiple myeloma, breast cancer, small cell lung cancer, ovarian cancer, neuroblastoma, retinoblastoma, Ewing sarcoma, soft tissue sarcoma, and acute leukemia and chronic lymphocytic leukemia, etc. It also has a certain effect on testicular tumors, head and neck squamous cell carcinoma, na...
