Cross-linker (genipin) was also added towards the film along with the tissue repair strength compared with the strength of plain films. The adhesive was also bonded in vivo towards the sciatic nerve of rats and also the thermal harm induced by the laser assessed 4 days postoperatively. The experimental results demonstrated that chitosan adhesives successfully repaired intestine tissue, attaining the maximum repair strength in the laser energy of 120 mW. Effect on healing of burns–In a study using a rat model, Jin et al. compared the effects of chitosan with heparin on early extension of burns [51]. Chitosan powder, heparin powder as well as the mixture of chitosan and heparin were applied, towards the burns developed around the backs of rats. Histological examination immediately after 72 h showed that the burn degree of the chitosan-treated group was less serious than that on the handle group, and chitosan greatly prevented the extension of burns in early phase. In contrast, heparin had no protective impact on the early extension of burns. Use of chitosan and heparin with each other attenuated chitosan’s protective effect. Alsarra investigated the wound-healing efficacy of chitosan with distinct molecular weight and DDA ranges on rat burns [40]. The highest wound-healing price was located inside the group treated with high-molecular-weight and high-DDA chitosan. Burns treated with highmolecular-weight chitosan had considerably much more epithelial tissue, and also the very best reCB1 Activator Storage & Stability epithelialization and fastest wound closure were located with the high-molecular-weight chitosan therapy group. Histological examination and collagenase activity studies revealed sophisticated granulation tissue formation and epithelialization in wounds treated with highmolecular-weight chitosan. A study on the evaluation of chitosan gel with 1 silver sulfadiazine for burn wound treatment in rats was undertaken by Nascimento et al. [36]. Chitosan gel was applied to the burns every 48 h. The burns treated with chitosan gel with silver sulfadiazine showed a greater fibroblast production along with a superior angiogenesis than those treated with chitosan gelNIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author ManuscriptExpert Rev Anti Infect Ther.

Even though no statistical difference was discovered within the healing time among the groups, the authors suggested that chitosan gels pose advantages more than the silver sulfadiazine cream, since the former was applied every single 48 h, whereas the latter was applied every 24 h. On the other hand, the presence of silver sulfadiazine inside the chitosan gel does not look to contribute to the epithelialization method. A chitosan hydrogel was developed by Ribeiro et al. and its applicability as a wound dressing for burn wound in rats was evaluated [52]. The results from the initial in vitro study indicated that chitosan hydrogel was in a position to promote cell adhesion and proliferation. Cell DP Agonist web viability research showed that the hydrogel and its degradation by-products are noncytotoxic. From macroscopic analysis, the wound beds with the animals treated with chitosan hydrogel have been significantly smaller than those of untreated controls. Histological analysis revealed a lack of a reactive or maybe a granulomatous inflammatory reaction in skin lesions with chitosan hydrogel plus the absence of pathological abnormalities in the organs obtained by necropsy, which supported the local and systemic.
