Quantification of the normalized fluorescence intensity of LDH leakage as a function of chitosan treatments. The fluorescence intensity in the PBS group was used as the control. Note that all chitosan treatments significantly decreased the fluorescence intensity of LDH leakage following the compression injury, *P < 0.05 (Dunnett test). A statistical difference was not observed between chitosan treatments of different DA and MW, P > 0.05 (Tukey test). N = 6.
