Three different vancomycin concentrations of 1\u00a0mg\/mL, 10\u00a0mg\/mL, and 100\u00a0mg\/mL were applied in a semi-open, self-constructed diffusion chamber. Protein quantitation and electrophoresis were performed to monitor proteins in the dura perfusates at different time points. High resolution liquid-chromatography mass spectrometry was performed for the measurement of time-dependent relative mass transfer of vancomycin at different time points.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      While previous results for a diffusion unlimited scenario utilizing second-harmonic generation microscopy (SHG) on dura mater thin sections showed concentration-dependent changes manifesting as tissue section swelling over time and a loss in SHG intensity (Schultz et al.

Specifically, protein release at a dosage of 10\u00a0mg\/mL was notably higher than that in the cryo-control group (2\u201310\u00a0min). Our results showed that the relative mass transfer of vancomycin was greater (mean 3.9%) for the 1\u00a0mg\/mL vancomycin experiment and the 10\u00a0mg\/mL vancomycin experiment (mean 4.8%) compared to the 100\u00a0mg\/mL vancomycin experiment (0.69%).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Through biochemical analysis, our research provides novel perspectives on how different concentrations of vancomycin impact the dura mater.
