درمان زخمها يكي از مسائلي است كه بشر سالها با آن روبهرو بوده است و تلاشها براي يافتن تركيباتي كه ضمن بهبود زخمها، داراي عوارض جانبي نباشند، اهميت دارد. از آنجا كه عصاره گل بنفشه داراي اثرات ضدالتهابي و ضدعفونيكنندگي است، در مطالعه حاضر، اثر اين گياه بر ترميم زخم پوستي مورد بررسي قرار ميگيرد.
مواد و روشها: بدين منظور تعداد 32 سر موش صحرايي نر نژاد ويستار، بعد از ايجاد زخم پوستي تمام ضخامت بهوسيله شابلون 2 در 2 سانتيمتر در ناحيه خلفي گردن در 4 گروه برابر، شامل: گروه كنترل (بدون انجام درمان)، گروه دريافتكننده اوسرين، گروه دريافتكننده سولفاديازين نقره 1 درصد و گروه تجربي (درمان زخم توسط پماد عصاره گل بنفشه 20 درصد، دوبار در روز) قرار گرفتند. در طي مطالعه، هر 3 روز يكبار، طول و عرض زخم ها اندازه گيري شد. همچنين در روزهاي 3، 7، 14 و 21 پس از ايجاد زخم، موشها آسانكشي شدند و بافتهاي ترميميافته، جهت مطالعات هيستوپاتولوژيك مورد بررسي قرار گرفتند.
نتايج: نتايج نشاندهنده كاهش معنيدار مساحت زخم در حيوانات تحت درمان بهخصوص گل بنفشه در مقايسه با گروه كنترل بود (0/05

Wound healing is an important concern that humankind is facing and attempting
to find compounds that have the least side effects on wound healing is important. Since violet
flower extract has anti-inflammatory and disinfection effects, in this study the impact of this
plant on wound healing was examined.
Materials and Methods: 32 rats were provided from the laboratory animal breeding center
in Shahrekord, and after anesthetizing them, a full-thickness skin wound was created by a 2
by 2 Cm stencil in the posterior cervical region. The control group received no treatment, one
group received Eucerin, another group received Silver Sulfadiazine 1% and the experimental
group received ointment of violet flower extract 20% twice a day. Throughout the study, the
length and width of the wounds were measured in each group every three days. On the 3rd,
7th, 14th and 21st days after creating the wound, the rats were anesthetized and the healed
tissues were examined for histopathologic studies.
Results: The results showed a significant reduction in wound area in treated animals,
especially violets, compared with the control group (P<0.05). Histopathologically, the
thickness of the epithelium and the amount of collagen showed a significant increase in the
experimental group of violets.
Conclusion: This can probably be attributed to the anti-inflammatory effects of the effective
components of violet flower. also it’s likely that these components stimulate collagen
production and quicker contraction of wounds. Therefore, the compounds of this plant can be
used to treat wounds.
