Myorelaxant Effect of Transdermal Cannabidiol Application in Patients with TMD: A Randomized, Double-Blind Trial.

jcm-logo “The healing properties of cannabidiol (CBD) have been known for centuries.

In this study, we aimed to evaluate the efficiency of the myorelaxant effect of CBD after the transdermal application in patients with myofascial pain.

Results: in Group1, the sEMG masseter activity significantly decreased (11% in the right and 12.6% in the left masseter muscles). In Group2, the sEMG masseter activity was recorded as 0.23% in the right and 3.3% in the left masseter muscles. Pain intensity in VAS scale was significantly decreased in Group1: 70.2% compared to Group2: 9.81% reduction. Patients were asked to apply formulation twice a day for a period of 14 days.

Conclusion: The application of CBD formulation over masseter muscle reduced the activity of masseter muscles and improved the condition of masticatory muscles in patients with myofascial pain.”

Activation of Cannabinoid Receptors Promote Periodontal Cell Adhesion and Migration.

Journal of Clinical Periodontology banner“Medical and recreational cannabis use is increasing significantly, but its impacts on oral health remains unclear.

The aim of this study is to investigate the effects of tetrahydrocannabinol (THC), the major active component in cannabis, on periodontal fibroblast cell adhesion and migration to explore its role in periodontal regeneration and wound healing.

RESULTS:

Both CB1 and CB2 were expressed in periodontal tissues but with different expression patterns. THC promoted periodontal cell wound healing by inducing HPLF cell adhesion and migration. This was mediated by focal adhesion kinase (FAK) activation and its modulation of MAPK activities. The effect of cannabinoids on periodontal fibroblast cell adhesion and migration were mainly dependent on the CB2.

CONCLUSION:

These results suggested that cannabinoids may contribute to developing new therapeutics for periodontal regeneration and wound healing.”

Cannabinoid CB2R receptors are upregulated with corneal injury and regulate the course of corneal wound healing.

Experimental Eye Research

“CB2R receptors have demonstrated beneficial effects in wound healing in several models. We therefore investigated a potential role of CB2R receptors in corneal wound healing. We examined the functional contribution of CB2R receptors to the course of wound closure in an in vivo murine model. We additionally examined corneal expression of CB2R receptors in mouse and the consequences of their activation on cellular signaling, migration and proliferation in cultured bovine corneal epithelial cells (CECs). Using a novel mouse model, we provide evidence that corneal injury increases CB2R receptor expression in cornea. The CB2R agonist JWH133 induces chemorepulsion in cultured bovine CECs but does not alter CEC proliferation. The signaling profile of CB2R activation is activating MAPK and increasing cAMP accumulation, the latter perhaps due to Gs-coupling. Lipidomic analysis in bovine cornea shows a rise in acylethanolamines including the endocannabinoid anandamide 1 h after injury. In vivo, CB2R deletion and pharmacological block result in a delayed course of wound closure. In summary, we find evidence that CB2R receptor promoter activity is increased by corneal injury and that these receptors are required for the normal course of wound closure, possibly via chemorepulsion.”

Cannabis sativa: A comprehensive ethnopharmacological review of a medicinal plant with a long history.

Journal of Ethnopharmacology

“Cannabis sativa L. (C. sativa) is an annual dioecious plant, which shares its origins with the inception of the first agricultural human societies in Asia. Over the course of time different parts of the plant have been utilized for therapeutic and recreational purposes, for instance, extraction of healing oils from seed, or the use of inflorescences for their psychoactive effects. The key psychoactive constituent in C. sativa is called Δ-9-tetrahydrocannabinol (D9-THC). The endocannabinoid system seems to be phylogenetically ancient, as it was present in the most primitive vertebrates with a neuronal network. N-arachidonoylethanolamine (AEA) and 2-arachidonoyl glycerol (2-AG) are the main endocannabinoids ligands present in the animal kingdom, and the main endocannabinoid receptors are cannabinoid type-1 (CB1) receptor and cannabinoid type-2 (CB2) receptor.

AIM OF THE STUDY:

The review aims to provide a critical and comprehensive evaluation, from the ancient times to our days, of the ethnological, botanical, chemical and pharmacological aspects of C. sativa, with a vision for promoting further pharmaceutical research to explore its complete potential as a therapeutic agent.

RESULTS AND CONCLUSIONS:

A detailed comparative analysis of the available resources for C. sativa confirmed its origin and traditional spiritual, household and therapeutic uses and most importantly its popularity as a recreational drug. The result of several studies suggested a deeper involvement of phytocannabinoids (the key compounds in C. sativa) in several others central and peripheral pathophysiological mechanisms such as food intake, inflammation, pain, colitis, sleep disorders, neurological and psychiatric illness. However, despite their numerous medicinal benefits, they are still considered as a menace to the society and banned throughout the world, except for few countries. We believe that this review will help lay the foundation for promoting exhaustive pharmacological and pharmaceutical studies in order to better understand the clinical relevance and applications of non-psychoactive cannabinoids in the prevention and treatment of life-threatening diseases and help to improve the legal status of C. sativa.”

Cannabidiol restores differentiation capacity of LPS exposed adipose tissue mesenchymal stromal cells.

Experimental Cell Research

“Multipotent mesenchymal stromal cells (MSCs) support wound healing processes. These cells express toll-like receptors (TLRs). TLRs perform important key functions when the immune system is confronted with danger signals. TLR ligation by lipopolysaccharides (LPS) activates MSCs and induces intracellular signaling cascades, which affect their differentiation profile, increase the release of inflammatory cytokines and the production of reactive oxygen species. Continuing exposure to LPS triggers prolonged inflammatory reactions, which may lead to deleterious conditions, e.g. non-healing wounds.

Cannabidiol (CBD) exerts anti-inflammatory processes through cannabinoid receptor dependent and independent mechanisms. In the present study, we examined whether CBD could influence the inflammatory MSC phenotype.

Exposure to LPS increased the release of IL-6, as well as other soluble factors, and elevated levels of oxidized macromolecules found in cell homogenisates. While the amount of IL-6 was unaffected, co-treatment with CBD reduced the oxidative stress acting on the cells. LPS inhibited adipogenic as well as chondrogenic differentiation, which was attenuated by CBD treatment. In the case of adipogenesis, the disinhibitory effect probably depended on CBD interaction with the peroxisome proliferator-activated receptor-γ.

CBD could exert mild immunosuppressive properties on MSCs, while it most effectively acted anti-oxidatively and by restoring the differentiation capacity upon LPS treatment.” https://www.ncbi.nlm.nih.gov/pubmed/30036540

“Boy’s miracle recovery from rare cancer after mum gave him cannabis”  http://metro.co.uk/2017/03/26/boys-miracle-recovery-from-rare-cancer-after-mum-gave-him-cannabis-6534160/

“A mother in England reports that she secretly gave her son marijuana, and credits it with curing his leukemia, and saving the teen’s life. Callie Blackwell chose to secretly give her dying son illegally bought marijuana to help him deal with the pain and anxiety from his aggressive leukemia, because she felt he had “nothing else to lose,” The Independent reported. The drug did far more than the mother could have hoped; it not only relieved Deryn’s pain, it reportedly cured his cancer. Now, Blackwell hopes to share her family’s story in an effort to raise awareness about the healing potential of marijuana.

Deryn was first diagnosed with his severe and aggressive form of leukemia, a type of cancer that originates in the blood cells, at age 10. At 14, doctors informed him that there was nothing more they could do, and the young teen went to live out the rest of his short life in a hospice facility. However, that was three years ago, and now at 17, Deryn has fully recovered from his disease and plans to start a career in the food industry. Callie teamed up with author Karen Hockney to write The Boy in 7 Million, a book detailing the family’s experience and highlighting the potential of marijuana in cancer treatment.

There have been a number of instances where marijuana was suspected of significantly improving, and in some cases even curing cancer, but the science remains inconclusive. Research suggests that cannabinoids—chemicals found in the marijuana plants—can target and kill cancer cells in ways that drugs cannot.” http://www.medicaldaily.com/can-marijuana-cure-cancer-mom-claims-have-cured-sons-leukemia-secretly-giving-414375

Effects of JWH015 in cytokine secretion in primary human keratinocytes and fibroblasts and its suitability for topical/transdermal delivery.

Image result for Mol Pain.

“JWH015 is a cannabinoid (CB) receptor type 2 agonist that produces immunomodulatory effects. Since skin cells play a key role in inflammatory conditions and tissue repair, we investigated the ability of JWH015 to promote an anti-inflammatory and pro-wound healing phenotype in human primary skin cells.

The expression of CB1 and CB2 receptors (mRNA) and the production of pro- and anti-inflammatory factors enhanced in keratinocytes and fibroblasts following lipopolysaccharide stimulation. JWH015 reduced the concentration of major pro-inflammatory factors (IL-6 and MCP-1) and increased the concentration of a major anti-inflammatory factor (TGF-β) in lipopolysaccharide-stimulated cells.

JWH015 induced a faster scratch gap closure. These JWH015’seffects were mainly modulated through both CB1 and CB2 receptors. Topically administered JWH015 was mostly retained in the skin and displayed a sustained and low level of transdermal permeation.

Our findings suggest that targeting keratinocytes and fibroblasts with cannabinoid drugs could represent a therapeutic strategy to resolve peripheral inflammation and promote tissue repair.”

Accelerated Burn Wound Closure in Mice with a New Formula Based on Traditional Medicine.

Image result for Iran Red Crescent Med J.

“A combination of the oils of sesame, hemp, wild pistachio, and walnut has been used for treatment of skin disorders, including wound burns, in some parts of Kerman, Iran. Evaluation of this remedy in the form of a pharmaceutical formulation in animal models can pave the way for its future application in wound burn healing in humans.

This experimental study investigated the healing potential of a new formula (NF) based on folk medicine from Iran for the treatment of third degree burns in mice. The formula was a combination of the oils of four plants: sesame (Sesamum indicum L.), wild pistachio (Pistacia atlantica Desf.), hemp (Cannabis sativa L.), and walnut (Juglans regia L.).

When compared to the controls, NF significantly improved wound contraction after day 10. Histopathological and immunohistochemical findings confirmed the efficacy of the NF.

CONCLUSIONS:

A new therapeutic remedy was introduced for the treatment of burn wounds.

Further clinical and molecular studies are suggested to determine the exact mechanism(s) involved in the burn wound healing effect of NF.”

In vitro Antimicrobial and Antioxidant Activity of Extracts from Six Chemotypes of Medicinal Cannabis

“Nowadays, medicinal cannabis (Cannabis sativa L) is in the focus of the researches not only for its high content of tetrahydrocannabinol (THC), but for other cannabinoids as well.

It has been reported that some of the identified substances (e.g. cannabidiol, cannabinochromene) possess anti-inflammatory and antimicrobial properties, which corresponds to its traditional use as wound healing agent at Pakistan.

The aim of this study was to evaluate antimicrobial and antioxidant ability of extracts from high potent Cannabis sativa chemotypes.

The six ethanolic extracts prepared from dried inflorescence of five medicinal cannabis chemotypes (Nurse Jackie, Jilly Bean, Nordle, Jack Cleaner, Conspiracy Kush) were tested by standard microdilution method against Staphylococcus aureus (three strains), Streptococcus pyogenes and the yeast Candida albicans.

Those microbial strains are present on skin and can cause complication during wound healing process.

The antioxidative activity, which plays an important role in wound healing process, was tested by oxygen radical absorbance capacity test (ORAC).

All tested extracts demonstrated high antimicrobial activity against two strains of S. aureus and S. pyogenes (MIC ranged from 4 – 16 µg·mL-1), moreover high antioxidant capacity was observed (ORAC ranged from 800 – 1300 µg TE/mg of extract).

The results indicate that cannabis has high potential to be used in ointments and other material for wound healing.

However, further research on the identification of the active components is needed.”

Abnormal cannabidiol attenuates experimental colitis in mice, promotes wound healing and inhibits neutrophil recruitment.

“Non-psychotropic atypical cannabinoids have therapeutic potential in a variety of inflammatory conditions including those of the gastrointestinal tract.

Here we examined the effects of the atypical cannabinoid abnormal cannabidiol (Abn-CBD) on wound healing, inflammatory cell recruitment and colitis in mice.

TNBS-induced colitis was attenuated by treatment with Abn-CBD.

Abn-CBD is protective against TNBS-induced colitis, promotes wound healing of endothelial and epithelial cells and inhibits neutrophil accumulation on HUVEC monolayers.

Thus, the atypical cannabinoid Abn-CBD represents a novel potential therapeutic in the treatment of intestinal inflammatory diseases.”
