Embodiment 1

[0019] Example 1 Allergenicity Detection of Reduning Injection

[0020] 1. Method

[0021] 1. Sensitive parts of ultrafiltration enriched traditional Chinese medicine injection

[0022] Take respectively 100ml of Reduning injection (batch numbers: 100808, 111011, 101105, 101114) with known adverse reactions and Reduning injection (batch numbers: 110709, 120207, 120210, 120211) of the sample to be tested, and add Transfer to an ultrafiltration tube with a molecular weight cut-off of 3KD, centrifuge at 3500 rpm for 40 minutes, and after repeated ultrafiltration, the remaining 5ml solution is obtained from the 20-fold concentrated and enriched macromolecular allergenic sites of the above batch numbers, sterilized, and stored at 4 degrees.

[0023] 2. Co-culture of splenic mononuclear cell PBMC and stimulatory site

[0024] Take the ICR mouse and kill it by decapitation, soak it in 75% alcohol for 2 minutes, take it out, open the abdominal cavity, take out the spleen, put it in ...

Embodiment 2

[0038] Example 2 Sensitivity Detection of Salvia Miltiorrhiza, Radix Astragali, Shengmai, Puerarin, Xuesaitong Injection

[0039] 1. Method

[0040] 1. Sensitive parts of ultrafiltration enriched traditional Chinese medicine injection

[0041] Take 100ml each of Danshen, Astragalus, Shengmai, Puerarin, and Xuesaitong injections, add them to an ultrafiltration tube with a molecular weight cut-off of 3KD, and centrifuge at 3500 rpm for 40min. After repeated ultrafiltration, 20 and 60 times concentrated and enriched large Molecular sensitization parts, sterilized, stored at 4 degrees, and set aside.

[0042]2. Co-culture of splenic mononuclear cell PBMC and stimulatory site

Abstract

The invention provides a test evaluation method for sensitization of a traditional Chinese medicine injection. The method comprises the steps of: treating a traditional Chinese medicine injection by ultrafiltration enrichment with 1-3KD to prepare a sensitized large molecular part; then adding the large molecular part into a peripheral blood mononuclear cell (PBMC) solution; carrying out co-culture for 1-3 days; and employing optimized trypan blue or fluorescent dye to dye living cell numbers, in order to calculate and evaluate sensitization strength of the traditional Chinese medicine injection. The method has advantages of convenience, rapidness and sensitivity, can be widely used in test and evaluation on sensitization and irritation of various traditional Chinese medicine injections, and provides scientific basis for safety evaluation and quality control of traditional Chinese medicine injections, and safety of clinical medication.

Description

technical field [0001] The invention relates to a detection method, specifically designing a detection and evaluation method widely applicable to the sensitization and irritation of traditional Chinese medicine injections. Background technique [0002] Traditional Chinese medicine injection is a modern Chinese medicine preparation developed in the modernization of Chinese medicine. It has remarkable clinical efficacy and is widely used in respiratory, cardiovascular and cerebrovascular fields, and has achieved good market economic benefits. However, traditional Chinese medicine injections often have adverse reactions in clinical use, which has potential safety hazards. Adverse reactions have been reported for commonly used Chinese medicine injections in clinical practice, such as Shuanghuanglian, Qingkailing, Radix Isatidis, Houttuynia cordata, Chuanhuning, Mailuoning, Puerarin, and Compound Danshen. [0003] There are various types of adverse reactions, the most common bei...
