Background: Silibinin is a semi-purified fraction of silymarin contained in milk thistle (Silybum marianum Asteraceae). Primarily known for its hepatoprotective actions, silymarin may also stimulate epithelialization and reduce inflammation in excision wound. Previous studies show antioxidant, anti-inflammatory, and antimicrobial actions of silibinin. However, wound healing property of silibinin is not well studied. Objective: This study investigates wound healing activity of silibinin topical formulation. Materials and Methods: Wound healing activity of 0.2% silibinin gel was assessed by incision and excision wound models in mice. Animals were divided into gel base, silibinin gel, and Mega Heal gel® treated groups with six animals in each group. Wound contraction, wound tissue tensile strength, and hydroxyproline content were measured, and histopathological evaluation of wound tissue of all the above treatment groups was carried out. Results: Application of 0.2% silibinin hydrogel for 8 days led to 56.3% wound contraction compared to 64.6% using standard Mega Heal gel with a subsequent increase in hydroxyproline content, which was significantly higher (P < 0.001) over control animals showing 33.2% contraction. After 14 days, percentage of contraction reached 96.1%, 97.6%, and 86.7%, respectively. Wound tissue tensile strength with silibinin (223.55 ± 3.82 g) and standard (241.38 ± 2.49 g) was significantly higher (P < 0.001) than control (174.06 ± 5.75 g). Histopathology of silibinin and standard gel treated wound tissue showed more fibroblasts, fewer macrophage infiltration, and well-formed collagen fibers. Conclusion: Here, we show potent wound healing activity of silibinin hydrogel formulation.

   Introduction Top

The use of herbal medicines worldwide has given an excellent opportunity for India to look for therapeutic lead compounds from our ancient systems of medicine including Ayurveda, which can be used for the development of new therapeutically active compounds. Over 50% of all modern drugs have a natural origin, and they play an important role in drug development programs.[1] Traditional milk thistle (Silybum marianum Asteraceae) extract primarily mentioned in ayurvedic texts as hepatoprotective consists of about 65–80% silymarin (a flavonolignan complex) and 20–35% fatty acids. Silymarin is a complex mixture of polyphenolic molecules including seven closely related flavonolignans (silybin A, silybin B, isosilybin A, isosilybin B, silychristin, isosilychristin, and silydianin) and one flavonoid (taxifolin).[2] Silibinin, a semi-purified fraction of silymarin, is primarily a mixture of two diastereoisomers, silybin A and silybin B, in a roughly 1:1 ratio.[3],[4]

Wound is the physical injury that results in opening or breaking of the skin and proper method for the healing of wounds are essential for restoration of disrupted anatomical continuity and functional status of the skin.[5] Tissue repair and wound healing are a complex process that involves a series of biochemical and cellular reactions, beginning with inflammation and followed by reepithelialization, granulation tissue formation, and remodeling of the extracellular matrix.[6] During the inflammatory phase, macrophages mainly orchestrate the removal of fibrin and fibroblast proliferation. Wound healing proceeds only after the inflammation stops.[7] Although the healing process progresses naturally, an infection can seriously delay this healing process by prolonging the inflammatory phase, disrupting the normal clotting mechanisms, promoting disordered leukocyte function, and ultimately delaying angiogenesis.[8] Antioxidants counter excess protease and reactive oxygen species (ROS), often formed by neutrophil accumulation in the wound site and protect from oxidative damage. Fibroblasts and other cells killed by excess ROS and antioxidants may protect from these adverse events.[9] Therefore, a variety of activities such as fibroblast growth stimulation, anti-inflammatory, antioxidant, and antimicrobial effects can explain the traditional use of plants for helping wounds to heal. For in vivo evaluation of wound healing activity, the use of the single model is inadequate since no single model adequately represents the various phases of healing. Hence, we chose two different in vivo models (excision and incision wound models) to assess the effect of silibinin on wound tissue.[10] Incision wound models are more suitable for in situ techniques such as tensile strength, while excision wound models may provide enough material for determining biochemical and histological changes.[11] Silibinin has free radical scavenging property,[12],[13],[14],[15],[16] while it has also been shown to prevent inflammation by reducing, cytokines such as tumor necrosis factor-α, interleukin-1β levels in peripheral blood mononuclear cells in vitro.[17] It may also show anticancer activity.[18] Others have also shown antimicrobial actions of silibin [19] and silibinin.[20] Silymarin may stimulate epithelialization and reduce inflammation in excision wound model in rats.[21] Silibinin (20%) organogel formulation on prolonged application has been shown to treat skin wounds in rats by increasing collagen content.[22] In the present study, we show potent wound healing activity of silibinin (0.2%) hydrogel which was comparable with Mega Heal gel ® in mice.

Animal care and handling

Swiss male albino mice weighing 25–30 g of either sex were used in the study. Animals were procured from Laboratory Animal House of Birla Institute of Technology, Mesra (Reg. no: 621/02/ac/CPCSEA). All animal experiments strictly complied with approval of the Institutional Animal Ethical Committee. The animals were kept in polyacrylic cages and maintained under standard housing conditions of temperature (24–27°C) and humidity (60–65%) with 12:12 light: Dark cycles. They were acclimatized for 7 days. The food was provided in the form of dry pellets (Amrut Diet, New Delhi, India) and water ad libitum.

Gel preparation

Two mixtures were prepared: (a) 1 g carbopol 934 (Lubrizol CDH Chemicals, India) in distilled water with continuous agitation. (b) Methylparaben (0.5%; CDH Chemicals, New Delhi, India) in hot water and propylparaben (0.2%; CDH Chemicals, New Delhi, India) in propylene glycol (CDH Chemicals, New Delhi, India) were combined. The required quantity of silibinin mixed in distilled water with continuous stirring was added to mixture A, both the mixtures (a and b) were blended, and volume was made up to 100 mL. Triethanolamine (Sigma-Aldrich St. Lewis, MO, USA) was added dropwise to get neutral pH (6.8–7) and to obtain gel consistency, and then the prepared gel was packed in an airtight wide mouth container. Similar procedure was followed for the preparation of gel base.

Skin irritation test

In the skin irritation study, either sex of mice was used. Animals were divided into four groups. Hair was depleted from the back of mice with the help of depilatories and area 4 cm 2 was marked on both sides. One side served as control and the other as test. The animals were used after 24 h.[23] After hair depletion, the gel was applied by spatula once daily for 7 days, and the site was covered with a cotton bandage and observed for sensitivity and the reaction as erythema and edema.

Study design for wound healing activity

Incision and excision wound models were used to assess the wound healing profile of seed extract of Silybum marianum (silibinin; Sigma-Aldrich, St. Lewis, MO, USA) in mice (n = 6/group). The drug treatments were as follows:

  • Group A: Received gel base and served as normal controls
  • Group B: Received reference standard (Mega Heal gel ®; Aristo Pharmaceuticals Ltd., Mumbai, India)
  • Group C: Received silibinin gel (0.2% w/w).

Evaluation of wound healing activity

Wound healing activity was assessed by incision and excision wound healing models. All woundings were carried under ether anesthesia. Wounds were treated immediately after wound creation.

Incision wound model

Mice in each group were anesthetized, and two paravertebral-long incisions of approximately 1.5 cm were made through the skin and cutaneous muscles at a distance of about 1.0 cm from the midline on each side of the depilated back of the mice. No local or systemic antimicrobials were used throughout the experiment. After the incision was made, the parted skin was kept together and stitched with black silk thread at 0.5 cm interval. The wound was left undressed. Gel base, silibinin, and standard gel were administered once daily for 9 days at 11 a.m. to respective group of animals.

Evaluation of tensile strength

On day 10 when the wound has healed, sutures were removed under ether anesthesia. A small region of wound was cut so that the incision lies exactly in the middle of the previous wound area. Four small curved needles (No: 14) were pierced through the skin, two on either side. Two needles of one side were tied to a rod, whereas the other two needles were tied to a freely hanging plastic bottle. Slowly water was added to the bottle until the wound began to open. The amount of water in the bottle was weighed and considered as an indirect measure of wound tensile strength. The mean tensile strength of the paravertebral incisions on both sides of the animal was taken as the measures of the tensile strength of the wound for an individual animal. The tensile strength of silibinin and standard gel treated wounds was compared with gel base-treated control.[24]

Excision wound model

The mice were anesthetized with diethyl ether. After anesthesia, hair was removed by shaving the dorsal back of the mice. Ethanol (70%) was used as antiseptic for the shaved region before making the wound. Excision wound was made by removing a full thickness of the skin of 7 mm 2 circular area from a predetermined shaved area on the back of each animal. The wound was left undressed, and no local or systemic antimicrobial agent was used. Each mouse was placed in a separate cage.

Determination of wound contraction

After wound creation, experimental animals were divided into three groups as described earlier each group consisting of six animals. After surgery, the excision wound margins were traced by the changes in wound area planimetrically. The size of wounds was traced on a transparent paper every alternate day throughout the monitoring period; measurements were continued up to 14 days. From the tracings, wound surface area was evaluated.[10]

Percentage of wound contraction was determined using the following formula:

Percent wound contraction = (healed area/total area) ×100.

Histopathological evaluation

Excision wound model was used for histopathological evaluation. After deep ether anesthesia, a cross-section of full thickness skin (wound tissue) specimen from each group (n=3, standard gel, silibinin gel, or gel base-treated) was taken on day 10 of the experiment for histopathological evaluation. The tissue was cut into 5–10 µm sections using microtome and stained with hematoxylin and eosin. Stained tissue slides were examined under the Leica DME microscope (Leica Microsystems, Germany) (×40 objective). Photographs were captured using 7.1 M Pixel Canon PowerShot (Canon, India).

Estimation of hydroxyproline content

Hydroxyproline content was analyzed for 8-day postinjury granulation tissue. The hydrolyzed samples of wound tissue (30 mg) were mixed with 1 mL of 0.01 M CuSO4 followed by the addition of 1 mL of 2.5 N NaOH and 1 mL of 6% H2O2. The solution was mixed and shaken occasionally for 5 min. All the tubes (con, test and standard) were incubated at 80°C for 5 min with frequent vigorous shaking. Upon cooling, 4 mL of 3N H2 SO4 was added with constant agitation. Finally, 2 mL of 5% p dimethylaminobenzaldehyde was added and incubated at 70°C for 15 min and cooled in a water bath to 20°C. Absorbance was measured at 500 nm using a UV-VIS spectrophotometer (CE7200, Cecil Instruments Ltd., Cambridge, USA). Hydroxyproline content in the samples was calculated from standard hydroxyproline calibration curve.[25]

Statistical analysis

The data were analyzed using one-way analysis of variance followed by Tukey's post hoc test using GraphPad Prism 4.0 (San Diego, California, USA). The data were expressed as a mean ± standard error of mean. P < 0.05 was considered statistically significant.

Wound contraction for excision wound model

Excision wound model showed that all silibinin and standard gel-treated animals exhibited a significant increase in the percentage of wound contraction as compared to control groups over the period of 14 days (P < 0.01). Application of 0.2% silibinin gel for 8 days led to 56.3% wound contraction compared to 64.6% using standard, whereas control animals showed 33.2% contraction. After 14 days, both standard and silibinin treatment led to nearly complete healing of the wound (96.1% and 97.6%, respectively), whereas gel base-treated animals showed significantly less (P < 0.01) 86.7% healing [Table 2].

   Discussion Top

Proper healing of the wound is essential for restoration of disrupted anatomical continuity and disturbed functional status of skin.[26] Wound healing is a sequential process, which consists of different phases such as hemostasis, inflammation, proliferation, and remodeling.[27] The proliferative phase constitutes angiogenesis, collagen deposition, granulation, epithelialization, and wound contraction.[28]

Free radicals may potentiate wound formation while free radical scavenging has been associated with wound healing potential.[29] The free radical scavenging properties of S. marianum have been attributed to its flavonoids which may act as antioxidants.[30] Flavonoids are responsible for the free radical scavenging activity and are known to promote the wound healing process which is responsible for wound contraction and increased rate of epithelization.[31] Previous works, as well as preliminary studies in our laboratory show antioxidant property of silibinin.[32] Wounds are usually accompanied by pain as well as reddening and edema of the surrounding tissues. These are all classical symptoms of inflammation.[33] There are reports suggesting the anti-inflammatory potential of silibinin which was confirmed by our preliminary studies.[17] Here, we used two different in vivo models (excision and incision wound models) to assess the effect of silibinin on wound tissue.

Collagen deposition, granulation, epithelialization, and wound contraction are characteristics of proliferative phase of wound healing. Epithelial cells crawl across the wound bed to cover it, and myofibroblasts help it contract.[34] Wound contraction occurs throughout the healing process. Topical application of 0.2% silibinin showed an increase in the percentage of wound contraction as compared to control in excision wound model. Significant wound contraction and complete healing by 14th day indicated rapid epithelization and collagenization [Table 2]. The increase in tensile strength of wound tissue represents effective healing. It is an indicator of collagen synthesis and collagen maturation.[10] Collagen plays a central role in the healing of wounds, and it is a principal component of connective tissue which provides the structural framework for regenerating tissues. Collagen is made up of amino acid, hydroxyproline, the major component of extracellular matrix thus rendering strength and support to the tissue. Breakdown of collagen liberates free hydroxyproline and its peptides. Thus, hydroxyproline levels correlate well with the amount of tissue collagen and is an established indicator for tissue collagen turnover.[33] Here, 0.2% silibinin gel led to significant increase in hydroxyproline levels in wound tissue compared to control thus suggesting increase in collagen content upon treatment. In the incision model, 0.2% silibinin showed a significant increase in tensile strength as compared to control. Hence, we postulate 0.2% silibinin to increase the rate of collagen synthesis leading to increased tensile strength in wound tissue, helping the process of healing. Enhanced healing activity has been attributed to increased collagen synthesis and angiogenesis. This improves circulation, thus providing oxygen and nutrients, essential for the healing process of the wound site.[35] Rate of wound contraction may also be attributed to increased proliferation of fibroblasts and their subsequent transformation to myofibroblasts. Enhanced contractile property of myofibroblast may result in the shorter epithelialization period thus helping the wound heal faster.[23] Histopathological study of granulation tissue in 0.2% silibinin gel-treated wound showed more collagen fibers, fibroblasts, and proliferating blood capillaries (angiogenesis) compared to gel base-treated wound. This led to increased tensile strength in the wound tissue, resulting in effective wound healing.
