Antimicrobial performance of the stents. (A) The effectiveness of several groups' in vitro antibacterial treatments against clinically significant Staphylococcus aureus (left) and Escherichia coli (right). The antibacterial activity against clinical microorganisms was greater in the CS/NHA/CD+NIR group. The mean and standard deviation of the values are shown; *p<0.05, **p<0.01. (B) H&E staining of samples collected from the various groups. The CS/nHA/CD+NIR group had a limited number of lobulated neutrophils (orange arrows), while the CS/nHA+NIR group had a large number of lobulated neutrophils. (C) After the specimens were taken, they were given in vivo treatment for a week, and then they were incubated for 24 hours. The number of colonies of clinically relevant S. aureus (top) and E. coli (bottom) were then counted. The mean and standard deviation of the values are shown; *p<0.05, **p<0.01. (D) Samples stained with Giemsa. Less bacteria in the CS/NHA/CD+NIR group (pink arrows), more bacteria in the CS/NHA+NIR group (blue arrows). Scaffold is represented by S [56]
