3.4. Histologic evaluation
On day 7 after burn induction, the biopsies of the burn areas
were histologically assessed. The biopsies from completely
3.4.1. Group 1 (control group)
We monitored the persistence of an active inflammatory
lesion with necrosis of the epidermis and dermis associated
with inflammatory cell infiltration, in the underlying tissue
(Fig. 4A and B). The dermis revealed the presence of edema
and pronounced hyperemia of capillary blood vessels. Some
slides showed also an abrasion of the coating surface and
vacuolar cell degeneration linked to an epithelial dystrophy.
3.4.2. Group 2 (reference group)
The histologic study depicted a complete healing manifested
with a thick retracted sclerotic tissue along with the persistence
of intradermal inflammation (Fig. 4C and D).
3.4.3. Group 3 (pumpkin oiletreated group)
A complete healing with a thin dermis was revealed associated
with a few inflammatory cells. However, we noticed a
branching of sebaceous annexes, an epithelial dystrophy, and
partly damaged hair follicles (Fig. 4E and F).
3.4.4. Group 4 (linseed oiletreated group)
There was complete tissue healing with thin epidermis associated
with an epithelial hypotrophy (Fig. 4G and H).
3.4.5. Group 5 (prickly pear oiletreated group)
There was complete tissue healing, in which the epidermis
was well organized (Fig. 4I and J).
