Ty against K162 site Staphylococcus aureus, Escherichia coli, and Green copper pseudomonas using disc diffusion method. It was revealed by Fig. 8 that GNPs-CS/KGM and Drug loaded Poly (dex-GMA/AAc) nanoparticles had strong inhibitory effect against the bacteria mentioned above while C75K25 film only had inhibitory effect against Staphylococcus aureus. The diameter of Bacteriostatic ring was shown in Table 4.Wound 56-59-7 healing effects of KGM/CS blend films and GNPsCS/KGMWound healing is an interaction of a complex cascade of biochemical and cellular events that generates resurfacing, reconstitution and restoration of the tensile strength of injured skin [39]. For evaluation of the wound healing capability of the preparations, percent wound contraction on incision wounds and histopathological studies were measured. First, we studied wound healing effects of blend film. As shown in Table 2, it was observed that postoperative wound area had slightly 11967625 contraction after 3d. The cut began to scab after 1 week and the scab become detached after 2 weeks with significant wound shrinkage. Healing of closed incisional wounds was also determined by the histopathological studies. Fig. 7 shows the histological studies on different KGM/CS formulae, CS film and gauze control group. Granulation tissue of wound became thickening gradually along with the increasing healing time. It was revealed by HE staining that inflammatory infiltration of different degree could be observed after 3d on all experiment and control group. Epidermal cell layer of treatment group proliferated actively after 7d and capillaries began 23148522 to form in dermis. Hierarchical structure was visible between epidermis and dermis. Epithelial structure such as stratum basale and acanthosis cell layer was observed in CS and C75K25 treatment group obviously, especially in C75K25 group, cuticular layer was also apparently visible. However, in gauge control group, no clear dermal tissue structures were formed and there was no hierarchical structure between epidermis and dermis after 7d. After 14d, the photomicrographs for the section of incision wound treated with treatment group especially C75K25 group showed significant hierarchical structure of epithelial tissue covering the wound area together with remodeling of welldeveloped collagen fibers that almost resembled normal tissue while in control group, there was still actively proliferated fibroblast in dermis. Cuticle, stratum granulosum, spinous cells layer, and basalis stratified clearly. Sections obtained from incision wounds treated with C75K25 revealed almost complete healing with nearly full resolution of the granulation tissue, normal tissue architecture, and new capillary distribution. It was known that CS itself has promoting wound healing effect and mixed with KGM could improve its mechanical properties. However, if the amount of KGM increased in CS/KGM, the solubility of film will increase and film-forming property will decrease. So when the proportion between CS and KGM reached 75 to 25, the CS/KGM film has the best mechanical properties and film-forming property. That’s why the histology study appears to favor the C75K25 films over the other formulations. Then GNPs-CS/KGM was also studied for wound healing effects. As shown in Table 3, contraction rate of GNPs-CS/KGM has significantly increased compared with gauze group (P,0.05)Hemostatic activities evaluationFirst, we compared the effects of Poly (dex-GMA/AAc) nanoparticles, C75K25 film, GNPs-CS.Ty against Staphylococcus aureus, Escherichia coli, and Green copper pseudomonas using disc diffusion method.
