Nowadays, there is an increasing knowledge that probiotic bacteria, topically applied, affects skin pathology. The objective of this study is to evaluate the effect on wound healing of locally applied probiotics by calculating the 3-D configuration of a standardized excisional wound. Fifty-two male Wistar rats were randomly allocated into groups: control, PRO1 [L. plantarum] and PRO2 [L. rhamnosus, B. longum]. Six excisional full-thickness wounds were created on each dorsum by an 8-mm circular biopsy punch; probiotics or saline were applied on days 0, 2, 4, 8, 16, photos of the wounds taken and specimens excised for histology [4 rats/group/time-point]. Both probiotic-groups exhibited accelerated healing significantly faster than the control, throughout, PRO2 exhibiting finally the best results [day 16]. However, only on day 2, did PRO1 exhibit the best results [wounded area, borders distance and epitheliazation line]. The results clearly demonstrate that the topical application of probiotics significantly improves the healing process, each strain working differently and more effectively in different healing phases. Thus, a combined formula containing different probiotics to modulate various healing phases is desirable. To this end our research continous.
如今,越来越多的人认识到,局部应用益生菌会影响皮肤病理学。本研究旨在通过计算标准化切除伤口的 3D 形态,来评估局部应用益生菌对伤口愈合的影响。52 只雄性 Wistar 大鼠被随机分为三组:对照组、PRO1[植物乳杆菌]和 PRO2[鼠李糖乳杆菌、长双歧杆菌]。通过 8mm 圆形活检冲孔在背部创建 6 个全层切除伤口;在第 0、2、4、8、16 天分别在伤口上涂抹益生菌或生理盐水,并拍摄伤口照片,每组 4 只大鼠/时间点切除标本进行组织学检查。两个益生菌组的愈合速度均明显快于对照组,PRO2 最终的效果最好[第 16 天]。然而,只有在第 2 天,PRO1 表现出最好的效果[伤口面积、边缘距离和上皮化线]。结果清楚地表明,益生菌的局部应用显著改善了愈合过程,每种菌株在不同的愈合阶段以不同的方式更有效地发挥作用。因此,需要一种含有不同益生菌的复合配方来调节不同的愈合阶段。为此,我们的研究仍在继续。
