Embodiment 1

[0016] Effects of Basil Polysaccharide on Three Kinds of Tumor Cells

[0017] Experimental material: basil polysaccharide is the basil polysaccharide finished product that adopts the extraction and separation method provided by the present invention to obtain; The human lung cancer cell line A549, the human laryngeal carcinoma cell line Hep -2 and human gastric cancer cell line SGC-7901.

[0018] Experimental method: Dissolve the finished basil polysaccharide in an appropriate amount of deionized water to prepare a solution with a concentration of 10 mg / ml, sterilize it, subpackage it and store it in a -20°C refrigerator for later use. Human lung cancer cell line A549, human laryngeal cancer cell line Hep-2 and human gastric cancer cell line SGC-7901 were conventionally cultured in RPMI1640 medium containing 10% newborn bovine serum (NBS), at 37°C, 5% CO 2 , cultured in a cell culture incubator with saturated humidity. Digest and passage with 0.25% trypsin. Take the culture...

Abstract

The invention discloses novel application of the pure traditional Chinese medicine preparation basil polysaccharide, namely application of basil polysaccharide as antineoplastic chemotherapeutic drug synergist in preparing antineoplastic drugs. The chemotherapeutic drug is cis-platinum, pirarubicin HCI or fluorouracil. As proved by experimental study, basil polysaccharide can enhance the functions of multiple chemotherapeutic drugs in inhibiting proliferation and activity of tumour cells (including lung cancer, laryngocarcinoma, stomach cancer and the like) from different tissue sources; in addition, according to a basil polysaccharide extracorporal cell experiment, the working concentration is free of toxicity, and basil polysaccharide is dose-dependent on the synergism of the chemotherapeutic drugs and has a clinical application prospect.

Description

technical field [0001] The present invention specifically relates to the new application of basil polysaccharide in the preparation of synergists of anti-tumor chemotherapeutic drugs, that is, the application of basil polysaccharides in the preparation of synergists of anti-tumor chemotherapeutic drugs, which belongs to the synergistic effect of traditional Chinese medicine on tumor chemotherapeutic drugs. technology field. Background technique [0002] Tumor is a disease that seriously endangers human health and life. Chemotherapy is a systemic treatment that uses chemical drugs to kill cancer cells, and is widely used in the clinical treatment of cancer patients. However, while killing cancer cells, it will inevitably damage the normal cells of the human body, resulting in a variety of adverse reactions, affecting the survival time and quality of life of cancer patients. Enhancing the efficacy of chemotherapy drugs, improving the quality of life of patients, and prolongi...
