Abstract
Background:
Manipulating intestinal microbiota with probiotics might stimulate skin
response. Understanding all stages of the healing process, as well as the
gut-skin-healing response can improve the skin healing process.
Aim:
To evaluate the effect of perioperative oral administration of probiotics on
the healing of skin wounds in rats.
Methods:
Seventy-two Wistar male adult rats were weighed and divided into two groups
with 36 each, one control group (supplemented with oral maltodextrin 250
mg/day) and one probiotic group (supplemented with Lactobacillus
paracasei LPC-37, Bifidobacterium lactis
HN0019, Lactobacillus rhamnosus HN001,
Lactobacillus acidophilus NCFM® at a dose of
250 mg/day), both given orally daily for 15 days. The two groups were
subsequently divided into three subgroups according to the moment of
euthanasia: in the 3rd, 7th and 10th
postoperative days.
Results:
There were no significant changes in weight in both groups. Wound contraction
was faster in probiotic group when compared to the controls, resulting in
smaller wound area in the 7th postoperative day. As for
histological aspects, the overall H&E score was lower in the probiotic
group. The probiotic group showed increased fibrosis from 3rd to
the 7th postoperative day. The type I collagen production was
higher in the probiotic group at the 10th postoperative day, and
the type III collagen increased in the 7th.
Conclusion:
The perioperative use of orally administrated probiotic was associated with a
faster reduction of the wound area in rats probably by reducing the
inflammatory phase, accelerating the fibrosis process and the deposition of
collagen.
