Embodiment 1
[0038] Example 1. Identification of cell proliferation activity
[0039] 1. Cell culture
[0040] Both human embryonic kidney cells (HEK-293T) and mouse sarcoma cells (S180) were treated with RPMI-1640 complete medium (containing 100 μg / ml streptomycin and 100 IU / ml penicillin) containing 10% fetal bovine serum by volume fraction, Place at 37°C, 5% CO 2 Cultured in a constant temperature incubator. The cells were digested with digestive solution (0.25% trypsin) and then passaged. The cells were passaged for more than three generations, and the cells in good condition were taken for future use.
[0041] 2. MTT colorimetric method to detect cell proliferation activity
[0042] 2.1 Establishment of cisplatin, doxorubicin, paclitaxel and camptothecin injury model
[0043] (1) Take HEK-293T cells in the logarithmic growth phase, adjust the concentration of the cell suspension to 1×10 with RPMI-1640 complete medium containing 10% fetal bovine serum 5 cells / mL, mix well and inoc...
Embodiment 2
[0063] Example 2. Morphological changes of HEK-293 cells observed by inverted microscope
[0064] Take HEK-293T cells in the logarithmic growth phase, adjust the cell suspension concentration to 2×10 with RPMI-1640 complete medium containing 10% fetal bovine serum 5 cells / mL, inoculate in a 6-well plate after mixing, 2 mL / well, in 5% CO 2 , Cultured in a 37°C incubator. After the cells were cultured for 24 hours, the experiments were performed in random groups. The groups were divided into: cisplatin damage model group (100 μM); cisplatin + rosin group (100 μM + 50 μM, 100 μM + 100 μM), rosin was given 1 hour in advance; normal control group, the same volume of medium was added. Each group had 3 replicate wells, in 5% CO 2 , Continue culturing in a 37°C incubator. After culturing for 24 hours, observe the changes of cell morphology in each group under an inverted microscope, take pictures with Olympus Image-ProPlus6.0 software and conduct comparative analysis. The result ...
Embodiment 3
[0066] Example 3. The effect of rosin on the survival rate of balb / c mice induced by cisplatin
[0067] Experimental method: 8-week-old Balb / c male mice were randomly divided into four groups, and the grouping conditions and treatments were as follows: ① Control group (n=10): hydroxypropyl-β-cyclodextrin solution was given by intragastric administration every day ; ②Cisplatin model group (n=12): cisplatin (20mg kg-1) was given by intraperitoneal injection once, and hydroxypropyl-β-cyclodextrin solution was given by intragastric administration every day for 6 consecutive days. Animal death situation; ③ cisplatin + low-dose rosin group (n=12): after one-time intraperitoneal injection of cisplatin (20mg kg-1), intragastric administration of hydroxypropyl-β-cyclodextrin package every day Combined rosin (6mg kg) was administered continuously for 6 days, and the animal death situation was observed every day; ④ Cisplatin + high-dose rosin group (n=12): one-time intraperitoneal inject...
