Fig. 7From: TAT-modified serum albumin nanoparticles for sustained-release of tetramethylpyrazine and improved targeting to spinal cord injuryIn vivo biodistribution of TMP.HCl and TAT-TMP-NPs in healthy rat and SCI rat. After the healthy rats and SCI rats were administrated with TMP.HCl and TAT-TMP-NPs, these rats were sacrificed and the heart, liver, spleen, lung, kidney and spinal cord were separated at 3 h (a, b), 8 h (c, d), and 12 h (e, f), respectively. Concentration of TMP was measured by HPLC. Data were expressed as mean ± standard deviation (n = 5). ANOVA (**P < 0.01, ****P < 0.0001) was used to assess the statistical differences between groupsBack to article page
