Description
BACKGROUND OF THE INVENTION
1. Field of the Invention

The present invention relates generally to wound healing, particularly to the use of combinations of certain herbs, certain herbal extracts and/or certain herbal molecular components, alone or in combination with known wound healing treatments, for enhancing migration of fibroblasts and/or keratinocytes to facilitate wound healing.


2. Description of the Related Art

Wound healing after injury is a complex process encompassing many cellular and biochemical events to restore tissue integrity. Wound healing generally involves re-epithelialization from the wound margin through keratinocyte proliferation and migration, and some growth factors are known to influence this process. See Syarina P. et al.; Wound healing potential of Spirulina platensis extracts on human dermal fibroblast cells. EXCLI Journal. 2015; 14:385-393, which is incorporated by reference. Human dermal fibroblasts also play significant roles in cutaneous wound repair and remodeling. They proliferate to expand, migrate into the wound bed, synthesize new ECM, and express thick actin bundles as myofibroblasts. It is desired to provide a treatment and/or supplement, including a safe and effective herbal combination, as a fibroblast and/or keratinocyte migration enhancer for improving skin wound healing efficiency.

An example method for preparation of an external cream in accordance with certain embodiments is provided below.


First, two of more of the herbs may be cooked, for example, as described elsewhere herein or as may be understood or determined by those skilled in the art. A cream is then prepared that may be somewhat more of less than half herbs and half cream, e.g., a 25%-75% liquid of herbs in 1:1 ratio and 25%-75% cream may be used. The herbs can also be prepared as a tincture, e.g., soaking the herbs in alcohol for a period of time such as 2 weeks in a ratio of 1:3, for example. This herbal liquid can then be mixed with the cream in the same way as described above.


The herbs may be prepared for cooking by grinding and/or homogenizing the herbs. Grinding may be achieved using a Dyno-mill run once to obtain, e.g., 250 nm particle sizes or multiple times down to, e.g., 150 nm particle sizes. A high pressure homogenizer may be used, whereby the mixture is pushed through a filter, e.g., a 0.2 μm filter. Sonication or ultrasound may also be used.


Straining may be performed to get an aqueous extract. Lyophilization or freeze drying may be performed to prepare the mixture for in vitro use. Solubilization may be performed along with selection of a concentration of the extract. A cream, tablet, capsule, nano-lipid carrier, nanogel, or nano-chrystals, or nano-particulates may be formulated for administration to human or animal patients.


Treatments described herein may also be effective against immunodeficiency diseases such as HIV and AIDS, as well as other conditions affecting or caused by disorders of the immune system. Herbal combinations of one or more of Rheum tanguticum, Rehmannia glutinosa and Lonicera japonica and/or one or more other herbs or molecules described herein may be administered as a nutritional supplement or as a supplement to an exercise regimen or as an energy supplement or as a pain relief supplement or as a diuretic or sleep aid.

Formulations may be prepared for oral or topical administration as long release, lipidized dosage compositions or as short release non-lipidized formulas.


A cooking process may be performed as in the example of FIGS. 1A-1B. Referring to FIG. 1A, a step 502 in a cooking process may include taking about 25-30 grams of a first herb, e.g., rheum tanguticum, and a second herb, e.g., Lonicera japonica, and grinding in a mixer grinder for three to five minutes or until a fine powder has been mixed and ground. A step 504 in the process may include taking about 75-80 grams of a third herb, e.g., Rehmannia glutinosa, and grinding in a mixer grinder for three to five minutes or until a fine powder has been mixed and ground.


A step 506 in the cooking process may further include grinding 25 grams of the first herb, e.g., rheum tanguticum, 25 grams of the second herb, e.g., Lonicera japonica, and 75 grams of the third herb, e.g., Rehmannia glutinosa, and mixing thoroughly to prepare a three herb combination (“3HX”).


A next step 508 may include weighing about 25 grams of the powdered three herb combination 3HX in a 2000 ml beaker or other suitable container. A next step 510 may include adding water (RT) to the 25 grams of powdered three herb combination 3HX in a ratio of about 20 ml water per gram of powdered three herb combination and pouring the mixture along with a magnetic bead into the beaker. A next step 512 may include allowing the aqueous three herb combination to soak in distilled water for around 15 minutes before boiling.


Referring now to FIG. 1B, a hot plate may be pre-heated, for 10 minutes, e.g., before keeping the beaker for boiling, as indicated at step 522. A step 524 may then include boiling the mixture to 85-90° C. A step 526 may include allowing the mixture to come down to 70-75° C. after removing the mixture from the hot plate. A step 528 may include covering the beaker properly with aluminum paper and cooking the mixture at 70° C. on a hot plate. A time of cooking in accordance with the example of step 530 from the beginning to the end should be around 60 minutes which includes boiling, cooling and cooking.


A next step 532 may include straining the mixture with the help of a manual strainer. A step 534 may involve filtering the sample and measuring the total volume obtained, as well as making up an obtained extract up to 425 ml, centrifuging the extract obtained after making up at 4000 rpm for 30 minutes and collecting the supernatant.


A cream or lotion or shampoo or ointment or patch or other topical formulation may be prepared. Also, a pill or container of pills may be prepared in lipidized or non-lipidized form, and coated or uncoated for extended release, timed release, sustained release, modified release, immediate release, quick release, delayed release, controlled release, controlled delivery, long-acting or sustained action.

Shampoos in accordance with various alternative formulations may include fewer than all of these nine components and they may include other active or inactive components known to those skilled in the art as having some advantage when included in a shampoo formula or in a medicinal combination for treating a skin condition such as psoriasis, eczema, melanoma, or dermatitis or hair loss or another head or scalp disorder or ailment.


A shampoo in accordance with certain embodiments includes one or more surfactants that may be known or discovered as being advantageous for cleaning hair with a shampoo. A primary surfactant may be included to provide flash foam for cleaning the hair by removing dirt and other impurities. A secondary surfactant may be included to provide stable foam and to reduce the harshness of the primary surfactant. A surfactant may be used that includes a charged, hydrophilic head group and a long, hydrophobic alkyl chain tail. Surfactants are configured to break molecular bonds between dirt and hair and to transport the dirt into an aqueous medium to be rinsed free from the hair and scalp. Examples of surfactants that may be contained in a shampoo in accordance with certain embodiments include sodium laureth sulphate, ammonium laureth sulfate, and sodium cocoyl isethionate. Examples of co-surfactants include cocamide MEA and cocoamidopropyl betaine.


A shampoo in accordance with certain embodiments may include a thickening or suspending agent. Examples of thickening or suspending agents that may be contained in accordance with certain embodiments include carbomer and PEG 150 distearate. The thickening agent may be included to stabilize the shampoo during storage and/or to prevent the setting or dumping of pigments and silicone.


A pH adjuster or buffer may be included in a shampoo in accordance with certain embodiments. An example of a pH adjuster or buffer includes citric acid, tartaric and sodium hydroxide. The pH adjuster or buffer is configured to cause the shampoo to be gentle to the skin. A lower pH may cause hair to be compact and to shine and to protect the surfactant from hydrolysis, and as such, the pH adjuster or buffer may serve to lower the pH of the shampoo. However, alternative embodiments include pH adjusters that serve to raise the pH of a shampoo that contains an herbal formula that exhibits an exceptionally low pH.


An aesthetic additive may be included in a shampoo in accordance with certain embodiments. Examples of aesthetic additives include colorants, opacifiers, UV absorbers, perfumes and natural and artificial fragrances.


One or more conditioners may be included in a shampoo in accordance with certain embodiments. The one or more conditioners may include a cationic polymer such as guar hydroxypropyl trimonium chloride. The one or more conditions may include silicone and/or a silicone emulsion such as dimethiconol, dimethicone, or amodimethicone. The silicone and/or silicone emulsion may serve to coat the hair and cause the hair to become soft, smooth and shiny.


A shampoo in accordance with certain embodiments includes one or more active herbs or herbal extracts or emotives that are described in several examples herein. These one or more active herbs or herbal extracts serve to promote treatment of certain hair and scalp conditions such as psoriasis, eczema, dermatitis, melanoma, hair loss and other hair or scalp conditions described herein or understood by those skilled in the art.


A preservative may be included in a shampoo in accordance with certain embodiments. The preservative may be configured to prevent microbial growth. Examples of preservatives that may be contained in a shampoo in accordance with certain embodiments include paraben free, formaldehyde donor free and halogenated free.


A moisturizer and/or one or more vitamins may be included in a shampoo in accordance with certain embodiments. Examples include combinations of D-Panthenol, vitamin E acetate, sodium PCA, glycerine and one or more amino acids. The moisturizer and/or vitamins may be configured to penetrate into hair shaft, seal cuticles and keep hair moisturized.


A shampoo in accordance with certain embodiments may include a hydro-alcoholic hair serum. Referring to FIG. 4, a hair growth cycle includes exogen, anagen, catagen and tetogen phases. The anagen phase involves active hair growth, whereby hair follicles regenerate and generate pigmented hair shafts. The telogen phase is a resting phase. The catagen phase involves cessation of hair growth and pigmentation, and release of papilla from the bulb.

The present study assessed the wound healing efficiency of four herbal compositions, namely, Herb1, Herb2, Herb3 and 3HX (which was selected as 1:1:3 in this study and may be a combination of Herb1, Herb2 and Herb3 in a ratio in various example embodiments of approximately a:b:c, wherein 1<b/a<2, and 1<c/b<4) by evaluating their potential to aid in migration of human dermal fibroblast cells into the wounded monalayer using in vitro scratch assay method.


Confluent monolayers of HFF-1 cells were scratched horizontally and vertically to obtain linear wounds using sterile 200 μl pipette tip and incubated with the test items at the non-cytotoxic concentrations ranging from 1:500 to 1:50 (test item: cell growth medium). Thereafter, the ability of the cells to migrate and repopulate the scratched area was evaluated microscopically and photomicrographs were captured after 16 hours. The results were quantified using the image analyzer software, ImageJ.


The results obtained in the present study indicate that amongst all the four test items, only the three herb combination, or 3HX, demonstrated dose dependent wound healing potential at all the tested concentrations. However, none of the three herbs alone exhibited any significant potential as a fibroblast migration enhancer for improving wound healing efficiency across the tested concentrations.

The stock solutions were then filtered through 0.22 μm syringe filter and diluted in DMEM (ie; cell growth medium) to obtain volume/volume concentrations corresponding to test item to cell growth medium ratios of 1:500, 1:200, 1:100, 1:75 and 1:50.


The concentrations obtained in the above step were used for subsequent treatment to the cells.


For formulation of a positive control, 100 μg/ml (PBS stock) of EGF was diluted in DMEM to achieve working concentrations ranging from 10 ng/ml—10,000 ng/ml (i.e., 10 fold or higher concentrations than the desired final concentrations in cells).


For determination of non-cytotoxic concentrations of test items and positive control (see Biological Evaluation of Medical Devices - Part 5: Tests for In Vitro Cytotoxicity (ISO 10993-5:2009), I.S.EN ISO, 10993-5:2009, which is incorporated by reference.), HFF-1 cells were counted using a haemocytometer and plated in a 96 well plate at the density corresponding to 5×103 cells/well/180 μl of DMEM supplemented with 15% FBS.


The above cells were then incubated overnight under growth conditions as described above so as to allow cell recovery and exponential growth.


After overnight incubation, the cells were subjected to serum starvation in DMEM so as to synchronize cell growth.


Following overnight incubation, the cells were treated with test items and positive control at the concentrations described above.


The above cells were then incubated for 16 hours in CO2 incubator at 37° C., 5% CO2 and 95% humidity.


Following incubation, the plates were taken out and 20 μl of 5 mg/ml of MTT [3-(4,5-dimethythiazol-2-yl)-2,5-diphenyl tetrazolium bromide] solution was added to all the wells followed by additional incubation for 3 h at 37° C. The supernatant was aspirated and 150 μl of DMSO was added to each well to dissolve formazan crystals. The absorbance of each well was read at 540 nm using Biotek Synergy HT micro plate reader.


The percentage cytotoxicity corresponding to each treatment was calculated using the following formula:





% Cytotoxicity=((R−X)/R)*100


Where X=Absorbance of treated cells at 540 nm

    • R=Absorbance of untreated cells at 540 nm


The concentrations exhibiting % cytotoxicity of <30% were considered as non-cytotoxic.


For assessment of the effect of test items on wound healing activity by scratch assay, HFF-1 cells were counted using hemocytometer and plated in 12 well plate at the density corresponding 0.08×106 cells/well in DMEM supplemented with 15% FBS.


The above cells were then incubated overnight under growth conditions (e.g., 37° C., 5% CO2, 95% Humidity), so as to allow the cell recovery and exponential growth.


Following overnight incubation, the cells were serum starved in DMEM so as to synchronize cell growth.


A small linear scratch (representative wound) was then created in the confluent monolayer by gently scraping horizontally and vertically with a sterile 200 μl micropipette tip.


The cells were then rinsed with serum free DMEM and grouped for treatment as follows: For baseline control, Cells plus DMEM were used. For positive/validation control, the baseline control plus EGF at non-cytotoxic concentrations (Stock solution serially diluted in serum free DMEM) were used. EGF was tested at the non-cytotoxic concentrations corresponding to 30 ng/ml. For tests 1-4, the baseline control plus the test items 1-4 of Table 1B. Test items 1-4 were each tested at five non-cytotoxic concentrations.


The above cells were then monitored for closure of wound area. Photomicrographs were captured after 16 hours and analyzed for quantitative assessment of area of wound closure using Image? software. The percentage migration corresponding to each treatment was calculated using the following formula:





% Migration=((R−X)/R)*100


Where X=% Scratched area of treated cells after 16 h, and

    • R=% Scratched area of untreated cells after 16 hours


Results

The percentage cellular cytotoxicity obtained in HFF-1 cells treated with different concentrations of test items or positive control for 24 hours is represented in Table 2.

The present study was conducted to assess the wound healing potential of four herbal formulations, namely Herb1, Herb2, Herb3 and 3HX, which is a combination of Herb1, Herb2 and Herb3 in a ratio a:b:c where 1<b/a<2 and 1<c/b<4, and in certain example embodiments in ratios 1:1:2, 1:1:2.5, 1:1:3, and 1:1:4. Human dermal fibroblast cells, HFF-1 were used as test system in the present study as these cells play a key role in wound re-epithelialization. Briefly, confluent monolayer of cells were scratched to generate a mechanical wound followed by treatment with the test items at volume/volume concentrations corresponding to test item to cell growth medium ratios of 1:500, 1:200, 1:100, 1:75 and 1:50 for 16 hours. The cells were visualized under inverted microscope for closure of wound. Thereafter, the cells were photomicrographed and the images were analysed using ImageJ software so as to quantitate the wound healing effect of the herbs.


The wound healing effect of Herb1 is shown in FIGS. 6A-6E and Table 3. When compared with untreated cells, Herb 1 did not demonstrate any wound healing effect.


The wound healing effect of Herb2 is shown in FIGS. 7A-7E and Table 3. When compared with untreated cells, Herb2 did not demonstrate any wound healing effect.


The wound healing effect of Herb3 is shown in FIGS. 8A-8E and Table 3. When compared with untreated cells, Herb3 did not demonstrate any wound healing effect.


The wound healing effect of 3HX (i.e., the combination of Herb 1, Herb 2 and Herb 3 at a ratio 1:1:3 in this example) is shown in FIGS. 9A-9E and Table 3. When compared with untreated cells, the three herb combination (3HX) demonstrated dose dependent enhanced migration of human dermal fibroblasts towards scratched area across all the tested concentrations. The quantitative analysis revealed that the herb led to an average of 19.39% increase in migration of dermal fibroblasts towards the scratched area as compared to the untreated cells after 16 hours. The overall effect ranged from 7.62% (at 1:50) to 30.34% (at 1:500) increase in migration of 3HX treated and wounded dermal fibroblast cells. The findings from the present study indicate that 3HX led to an increase in migration of human dermal fibroblast cells at all the tested concentrations.

Assessment of Wound Healing Potential of Test Items Using the Scratch Assay with Human Keratinocytes

The objective of this study was to assess the effect of test items on migration of human keratinocytes (HaCaT) on a mechanically created scratch. The present study assessed the wound healing efficiency of four herbs viz., Herb 1, Herb2, Herb3 and 3HX by evaluating their potential to aid in migration of human dermal fibroblast cells into the wounded monalayer using in vitro scratch assay method. Briefly, the confluent monolayers of HACAT cells were scratched horizontally and vertically to obtain a linear wounds using sterile 200 μl pipette tip and incubated with the test items at the non-cytotoxic concentrations ranging from 1: 500 to 1:50 (test item : cell growth medium). Thereafter, the ability of the cells to migrate and repopulate the scratched area was evaluated microscopically and photomicrographs were captured after 16 hours. The results were quantified using the image analyzer software, ImageJ. The results obtained in the present study indicate that amongst all the herbs, only Herb2 demonstrated wound healing potential at all the concentrations corresponding to 1:500, 1:200, 1:100 and 1:75. However, the other three herbs namely, Herb 1, Herb3 and 3HX did not exhibit any wound healing potential across the tested concentrations.
