Historical essay: An Arabic surgeon, Ibn al Quff’s (1232-1286) account on surgical pain relief.

“This is a review of Ibn al Quff’s account of surgical pain relief in his surgical book Al Omdah, in which he mentioned the word anesthetic (Al moukhadder) and the involvement of physician (al tabbaaee) to give mixture of drugs to prevent pain in a surgical condition to relieve the patient from pain or to make surgical management possible.

Hich indicated one rare occasion to such description in Arabic medical texts. Methods of administration of these drugs were inhalation, ingestion and by rectal suppositories.

The drugs used in anesthetic sponges include all the drugs that are recorded in the modern literature of anesthesia. They are as follows: opium, mandrake, Hyocymus albus, belladonna, Cannabis sativus, Cannabisindica, wild lettuce.

The anesthetic sponge, mentioned in many references as an inhalation method, may be of symbolic value to surgery.”

“Ibn al-Quff (1233-1286 AD), a medieval Arab surgeon and physician. Abū’l-Faraj ibn Ya’qūb ibn Isāq Ibn al-Quff al-Karakī (1233-1286 AD), best known as Ibn al-Quff in the West, was a 13th century Arab physician-surgeon. During his lifetime, Ibn al-Quff made some important contributions to the art of healing. He authored several books and commentaries in the field of medicine, in particular surgery.”  http://www.ncbi.nlm.nih.gov/pubmed/24585631

Effects of Cannabinoids on T-cell Function and Resistance to Infection.

“This review examines the effects of cannabinoids on immune function, with a focus on effects on T-cells, as well as on resistance to infection. The paper considers the immune modulating capacity of marijuana, of ∆9-THC extracted from the marijuana plant, and synthetic cannabinoids…

The overall conclusion of the studies discussed in this review is that cannabinoids that bind to the CB2 receptor, including ∆9-THC and CB2 selective agonists are immunosuppressive.

The studies provide objective evidence for potentially beneficial effects of marijuana and ∆9-THC on the immune system in conditions where it is desirable to dampen immune responses.

An emerging area of investigation that is reviewed is evidence to support the conclusion that CB2 selective agonists are a new class of immunosuppressive and anti-inflammatory compounds that may have exceptional beneficial effects in a variety of conditions, such as autoimmune diseases and graft rejection, where it is desirable to dampen the immune response without psychoactive effects.”

Unfazed or Dazed and Confused: Does Early Adolescent Marijuana Use Cause Sustained Impairments in Attention and Academic Functioning?

“There was no evidence indicating that adolescents who used marijuana experienced lingering attention and academic problems, relative to their pre-onset levels, after abstaining from use for at least a year.

These results suggest that adolescents who engage in low to moderate marijuana use experience an increase in observable attention and academic problems, but these problems appear to be minimal and are eliminated following sustained abstinence.”

A sativex-like combination of phytocannabinoids as a disease-modifying therapy in a viral model of multiple sclerosis.

“Sativex® is an oromucosal spray, containing equivalent amounts of Δ9 -tetrahydrocannabinol (Δ9 -THC) and cannabidiol (CBD)-botanical drug substance (BDS), and which has been approved for the treatment of spasticity and pain associated to multiple sclerosis (MS).

In this study, we investigated whether Sativex® may also serve as a disease-modifying agent in the Theiler’s murine encephalomyelitis virus induced demyelinating disease model of MS…

The data support the therapeutic potential of Sativex® to slow MS progression and its relevance in CNS repair.”

Cannabidiol, a Major Non-Psychotrophic Cannabis Constituent Enhances Fracture Healing and Stimulates Lysyl Hydroxylase Activity in Osteoblasts.

“Cannabinoid ligands regulate bone mass, but skeletal effects of cannabis (marijuana and hashish) have not been reported. Bone fractures are highly prevalent, involving prolonged immobilization and discomfort.

Here we report that the major non-psychoactive cannabis constituent, cannabidiol (CBD), enhances the biomechanical properties of healing rat mid-femoral fractures.

Using Fourier Transform Infrared Spectroscopy we confirmed the increase in collagen crosslink ratio by CBD, which is likely to contribute to the improved biomechanical properties of the fracture callus.

Taken together, these data show that CBD leads to improvement in fracture healing and demonstrate the critical mechanical role of collagen crosslinking enzymes.”

Smoking Marijuana Regularly May Reduce Risk of Some Neck, Head Cancers – Fox News

“You’ve heard about using marijuana and drugs derived from it to keep some of the side effects of toxic cancer chemotherapy in check. But what if smoking marijuana for 10 to 20 years could actually protect against certain tumors?

In a study, researchers have found that long-term pot smokers were roughly 62 percent less likely to develop head and neck cancers than people who did not smoke pot.”

Identification of the CB1 cannabinoid receptor and fatty acid amide hydrolase (FAAH) in the human placenta.

“Synthetic cannabinoids, the psychoactive components of the Cannabis sativa (marijuana) and their endogenous counterparts, act through two G protein-coupled receptors, CB1 and CB2.

The endocannabinoids are metabolized by fatty acid amide hydrolase (FAAH).

We have examined CB1 receptor and FAAH expression in human term placenta by immunohistochemistry.

CB1 receptor was found to be present in all layers of the membrane, with particularly strong expression in the amniotic epithelium and reticular cells and cells of the maternal decidua layer. Moderate expression was observed in the chorionic cytotrophoblasts. The expression of FAAH was the highest in amniotic epithelial cells, chorionic cytotrophoblast and maternal decidua layer.

Our results suggest that the human placenta is a likely target for cannabinoid action and metabolism. ”

Marijuana: A Time-Honored but Untested Treatment for Epilepsy.

“The biology of the endocannabinoid system in the brain provides a possible basis for a beneficial pharmacological effect of marijuana on seizures.

However, evidence for efficacy of cannabis treatment of epilepsy is anecdotal because no acceptable randomized controlled trials have been done.

Proper dosage and means of administration remain unknown.

Cannabis is safer than other controlled substances, including tobacco or alcohol, and appears to be relatively safe compared with most pharmaceuticals used to treat epilepsy.”

The role of cannabinoids in regulation of nausea and vomiting, and visceral pain.

“Marijuana derived from the plant Cannabis sativa has been used for the treatment of many gastrointestinal (GI) disorders, including anorexia, emesis, abdominal pain, diarrhea, and others.

Several cannabinoid receptors, which include the cannabinoid receptor 1 (CB1), CB2, and possibly GPR55, have been identified throughout the GI tract.

These receptors may play a role in the regulation of food intake, nausea and emesis, gastric secretion and gastroprotection, GI motility, ion transport, visceral sensation, intestinal inflammation, and cell proliferation in the gut.

…the regulation of nausea and vomiting by cannabinoids and the endocannabinoid system has shed new knowledge in this field.

Novel drug targets such as FAAH and monoacylglycerol lipase (MAGL) inhibitors appear to be promising in animal models, but more studies are necessary to prove their efficiency.

The promise of emerging drugs that are more selective and peripherally acting suggest that, in the near future, cannabinoids will play a major role in managing an array of GI diseases.”
