Hypothesis
The interaction of lithotripter shock waves and cytotoxic drugs enhances the effectiveness of the drugs.
Conclusion
The study found that shock waves significantly enhance the effectiveness of cisplatin and other cytotoxic drugs in killing cancer cells.
Supporting Evidence
- The dose enhancement ratio for cisplatin was 6.7 at 7 min incubation.
- Shock waves increased the effectiveness of drugs with lower cytotoxicity more than those with higher cytotoxicity.
- Proliferation was assessed using the MTT assay, showing significant differences in cell viability.
Takeaway
This study shows that using shock waves can help cancer drugs work better at killing cancer cells.
Methodology
L1210 cells were exposed to shock waves during incubation with various cytotoxic drugs, and their proliferation was measured using the MTT assay.
Limitations
Only a limited number of cytotoxic drugs were tested, and the study was conducted in vitro.
Participant Demographics
L1210 mouse leukemia cells were used in the experiments.
