Impacts of Danhong Injection on Physiological and Biochemical Indicators in Mice / 医药导报

ABSTRACT

Objective To explore the impacts of Danhong injection on physiological and biochemical indicators in malnourished mice at physiological low doses, evaluate its safety, and test the practical value of safety re-evaluation of Traditional Chinese Medicinal ( TCM) injections. Methods A total of 32 ICR mice during growth period were selected to set up corn deficient nutrition mice model. Mice were assigned into the normal control group (given 0. 9% saline), Danhong injection at low, medium and high dosages (0. 2, 0. 4 and 0. 6 mL) groups (n=8 in each group);Mice were administered with respective medications intraperitoneally for 7 consecutive days. Blood samples were taken and mice were executed on the 8th day. All 9 kinds of organ or tissue were obtained completely, to measure related physiological and serum biochemical parameters. The safety of Danhong injection was evaluated by using Benefit and Damage Index - General Score ( BDI-GS ) system. Results The Danhong injection showed only slight damages on major organs or tissues, the BDI values were all above 0. 85, and the GS values were all above 9. 0;BDI values for Danhong injection at different dosages were all above 1. 0 for spleen and pancreas, showing better replenishing and healthy effects, and the differences were of statistical significance compared with the normal control group (P<0. 05 or P<0. 01). Meanwhile, it exerted obviously hypoglycemic effect. Conclusion Danhong injection is of rather low risk under physiological dosages, and therefore is safe to use. The mal-nutrition model combined with the BDI-GS system may be developed as a novel approach for safety re-evaluation of TCM injection in clinic.
