Cannabis extract treatment for terminal acute lymphoblastic leukemia with a Philadelphia chromosome mutation.

” This case study is on a 14-year-old patient diagnosed with a very aggressive form of ALL (positive for the Philadelphia chromosome mutation). A standard bone marrow transplant, aggressive chemotherapy and radiation therapy were revoked, with treatment being deemed a failure after 34 months.

Without any other solutions provided by conventional approaches aside from palliation, the family administered cannabinoid extracts orally to the patient.

Cannabinoid resin extract is used as an effective treatment for ALL with a positive Philadelphia chromosome mutation and indications of dose-dependent disease control.

The clinical observation in this study revealed a rapid dose-dependent correlation.”

Effect of cannabinoid receptor activation on spreading depression.

“Cannabis has been used for centuries for both symptomatic and prophylactic treatment of different types of headaches including migraine…

Suppression of CSD (cortical spreading depression) by activation of CB1 receptors suggests the potential therapeutic effects of cannabinoids in migraine with aura as well as other CSD-related disorders.”

Using cannabis to help you sleep: Heightened frequency of medical cannabis use among those with PTSD.

“The use of cannabis for medical purposes is proliferating in the U.S., and PTSD is an explicitly approved condition for accessing medical cannabis in 5 states. Prior research suggests that people with PTSD often use cannabis to help cope with their condition…

Those with high PTSD scores were more likely to use cannabis to improve sleep, and for coping reasons more generally, compared with those with low PTSD scores. Cannabis use frequency was greater among those with high PTSD scores who used for sleep promoting purposes compared with those with low PTSD scores or those who did not use for sleep promoting purposes.

Consistent with prior research, this study found increased rates of coping-oriented use of cannabis and greater frequency of cannabis use among medical users with high PTSD scores compared with low PTSD scores. In addition, sleep improvement appears to be a primary motivator for coping-oriented use…”

Basolateral amygdala CB1 cannabinoid receptors mediate nicotine-induced place preference.

“In the present study, the effects of bilateral microinjections of cannabinoid CB1 receptor agonist and antagonist into the basolateral amygdala (intra-BLA) on nicotine-induced place preference were examined in rats.

Taken together, these findings support the possible role of endogenous cannabinoid system of the BLA in the acquisition and the expression of nicotine-induced place preference. Furthermore, it seems that there is a functional interaction between the BLA cannabinoid receptors and nicotine in producing the rewarding effects.”

Regulatory role of the Cannabinoid-2 receptor in stress-induced neuroinflammation in mice.

“Stress-exposure produces excitoxicity and neuroinflammation, contributing to the cellular damage observed in stress-related neuropathologies. The endocannabinoid system is present in stress-responsive neural circuits and it is emerging as a homeostatic system. The aim of this study was to elucidate the possible regulatory role of cannabinoid-2 receptor in stress-induced excitotoxicity and neuroinflammation.

CONCLUSIONS AND IMPLICATIONS:

These results suggest that pharmacological manipulation of CB2 receptor is a potential therapeutic strategy for the treatment of stress-related pathologies with a neuroinflammatory component, such as depression.”

Physiological intestinal oxygen modulates the Caco-2 cell model and increases sensitivity to the phytocannabinoid cannabidiol.

“The Caco-2 cell model is widely used as a model of colon cancer… these cells were more sensitive to cannabidiol-induced antiproliferative actions through changes in cellular energetics…

These effects could impact on its development as an anticancer therapeutic…”

Peripheral interactions between cannabinoid and opioid systems contribute to the antinociceptive effect of crotalphine.

“Crotalphine is an antinociceptive peptide… we evaluated the involvement of the peripheral cannabinoid system in the crotalphine effect and its interaction with the opioid system…

Crotalphine-induced antinociception involves peripheral CB2 cannabinoid receptors and local release of dynorphin A, which is dependent on CB2 receptor activation.

These results enhance our understanding of the mechanisms involved in the peripheral effect of crotalphine, as well as the interaction between the opioid and cannabinoid systems.”

Selective inhibition of FAAH produces antidiarrheal and antinociceptive effect mediated by endocannabinoids and cannabinoid-like fatty acid amides.

“The endogenous cannabinoid system (ECS) plays a crucial role in multiple physiological processes in the central nervous system and in the periphery. The discovery that selective cannabinoid (CB) receptor agonists exert a potent inhibitory action on gastrointestinal (GI) motility and pain has placed the ECS in the center of attention as a possible target for the treatment of functional GI diseases…

These data expand our understanding of the ECS function and provide a novel framework for the development of future potential treatments of functional GI disorders.”

Spontaneous regression of septum pellucidum/forniceal pilocytic astrocytomas–possible role of Cannabis inhalation.

“The purpose of this report is to document spontaneous regression of pilocytic astrocytomas of the septum pellucidum and to discuss the possible role of cannabis in promoting regression.

We report two children with septum pellucidum/forniceal pilocytic astrocytoma (PA) tumors… Neither patient received any conventional adjuvant treatment.

The tumors regressed over the same period of time that cannabis was consumed via inhalation, raising the possibility that the cannabis played a role in the tumor regression.”

Targeting astrocytomas and invading immune cells with cannabinoids: a promising therapeutic avenue.

“The last quarter century has borne witness to great advances in both the detection and treatment of numerous cancers. Even so, malignancies of the central nervous system, especially high-grade astrocytomas, continue to thwart our best efforts toward effective chemotherapeutic strategies.

With prognosis remaining bleak, the time for serious consideration of alternative therapies has arrived. Various preparations of the marijuana plant, Cannabis sativa, and related synthetic and endogenous compounds, may constitute just such an alternative.

Cannabinoids, although much maligned historically for their psychotropic effects and clear abuse potential, have long been used medicinally and are now staging an impressive comeback, as recent studies have begun to explore their powerful anti-tumoral properties.

In this study, we review in vitro and in vivo evidence supporting the use of cannabinoids for treatment of brain tumors. We further propose the continued intense investigation of cannabinoid efficacies as novel anti-cancer agents, especially in models recapitulating such properties within the unique environment of the brain.”
