incorporation of honey and Nepeta dschuparensis together into chitosan/poly(vinyl
alcohol) electrospun nanofibre triggers the healing rate of the wounds in animal
model. In in vivo experiment, the treatment of a second-degree burn injury of rats
has been carried out with developed dressing material, and the healing efficacy is
determined with respect to 1% silver sulfadiazine treated group (Naeimi et al. 2020).
A faster wound contraction is observed with the developed dressing material after
21 days of treatment which is further supported by the histopathological investiga-
tion. Minimal inflammation, higher angiogenesis and increased collagen deposition
are observed with the developed dressing material after 21 days of treatment, while
slow wound contraction, higher necrosis and less collagen deposition are
Fig. 30.2 In vivo study with different wound dressing materials: (a) the circular wounds on rats are
treated with vitexin-loaded chitosan hydrogel, madecassol and pure chitosan hydrogel, and the
wound contraction is observed with time; (b) the histopathological study exhibits superior healing
properties of herbal drug-loaded chitosan hydrogel in terms of re-epithelialization and vasculariza-
tion as compared to pure chitosan and madecassol group; (c) the excisional wounds on albino rats
are treated with herbal drug ‘panchavalkala’-loaded solution, PLA film and electrospun scaffold.
The wound contraction is observed with time and compared with control; and (d) the histopath-
ological studies indicates faster healing with drug-loaded scaffold in terms of greater angiogenesis,
construction of granulation tissues and less inflammation
