Abstract:
Objective To investigate the effect of ropivacaine preconditioning on the toxicity of ropivacaine to ND7/23 cells.Methods ND7/23 cells were cultured in DMEM culture medium at 37℃ in 5% CO2 incubator for 24 h at a concentration of 1 × 106/ml. The cells were randomly divided into 3 groups ( n = 3 each) ;control group (group C), ropivacaine group (group R) and ropivacaine preconditioning group (group RP). In group R, the cells were exposed to 1% ropivacaine 100 μl and incubated for 1 h. In group RP, the cells were exposed to 0.02% ropivacaine 100 μl for 15 min, after ropivacaine was washed out, 1% ropivacaine 100 μl was then added and the cells were incubated for 1 h. The cell viability was measured using CCK-8 assay and apoptosis using Annexin-V/PI staining.Results Compared with group C, the cell viability was significantly decreased, while the early apoptotic rate and late apoptotic rate were significantly increased in groups R and RP ( P ＜ 0.05). Compared with group R, the cell viability was significantly increased, while the early apoptotic rate and late apoptotic rate were significantly decreased in group RP (P ＜ 0.05) .Conclusion Ropivacaine preconditioning can protect ND7/23 cells from bupivacaine-induced cytotoxicity through inhibiting apoptosis.
