Evaluation of the role of the cannabidiol system in an animal model of ischemia/reperfusion kidney injury.

“This work aimed to investigate the effects of the administration of cannabidiol in a kidney ischemia/reperfusion animal model…

The cannabidiol treatment had a protective effect against inflammation and oxidative damage in the kidney ischemia/reperfusion model.

These effects seemed to be independent of CB1/CB2 receptor activation.”

Endocannabinoid Regulation of Neuroendocrine Systems.

“The hypothalamus is a part of the brain that is critical for sustaining life through its homeostatic control and integrative regulation of the autonomic nervous system and neuroendocrine systems. Neuroendocrine function in mammals is mediated mainly through the control of pituitary hormone secretion by diverse neuroendocrine cell groups in the hypothalamus.

Cannabinoid receptors are expressed throughout the hypothalamus, and endocannabinoids have been found to exert pronounced regulatory effects on neuroendocrine function via modulation of the outputs of several neuroendocrine systems.

Here, we review the physiological regulation of neuroendocrine function by endocannabinoids, focusing on the role of endocannabinoids in the neuroendocrine regulation of the stress response, food intake, fluid homeostasis, and reproductive function.

Cannabis sativa (marijuana) has a long history of recreational and/or medicinal use dating back to ancient times. It was used as an analgesic, anesthetic, and antianxiety herb as early as 2600 B.C.

The hedonic, anxiolytic, and mood-elevating properties of cannabis have also been cited in ancient records from different cultures. However, it was not until 1964 that the psychoactive constituent of cannabis, Δ(9)-tetrahydrocannabinol, was isolated and its chemical structure determined (Gaoni & Mechoulam, 1964).”

Characterization of Lignanamides from Hemp (Cannabis sativa L. ) Seed and their Antioxidant and Acetylcholinesterase Inhibitory Activities.

Image result for J Agric Food Chem.

“Hempseed is known for its content in fatty acids, proteins and fiber, which contribute to its nutritional value.

Here we studied the secondary metabolites of hempseed aiming at identifying bioactive compounds that could contribute to its health benefits.

This investigation led to the isolation of four new lignanamides cannabisin M, 2, cannabisin N, 5, cannabisin O, 8 and 3,3′-demethyl-heliotropamide, 10, together with ten known lignanamides, among which 4 was identified for the first time from hempseed.

Structures were established on the basis of NMR, HR-MS, UV, IR as well as by comparison with the literature data.

Lignanamides 2, 7, 9-14 showed good antioxidant activity among which 7, 10 and 13 also inhibited acetylcholinesterase in vitro.

The new identified compounds in this study added to the diversity of hempseed composition and the bioassays implied that hempseed, with lignanamides as nutrients, may be a good source of bioactive and protective compounds.”  http://www.ncbi.nlm.nih.gov/pubmed/26585089

“Alzheimer’s Disease (AD) is the most common single cause of dementia in our ageing society. On full assessment and diagnosis of AD, initiation of an AChe inhibitor is recommended as early as possible, it is important that AChe inhibitor therapy is considered for patients with mild to moderate AD.” https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2014378/

 “The Effects of Hempseed Meal Intake and Linoleic Acid on Drosophila Models of Neurodegenerative Diseases and Hypercholesterolemia. Our results indicate that hempseed meal (HSM) and linoleic acid are potential candidates for the treatment of Alzheimer’s disease (AD) and cardiovascular disease. These results show that HSM may prove of great utility as a health food, with potential for the prevention of AD and cardiovascular disease.” https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3933972/

The complete chloroplast genomes of Cannabis sativa and Humulus lupulus.

“Cannabis and Humulus are sister genera comprising the entirety of the Cannabaceae sensu stricto, including C. sativa L. (marijuana, hemp), and H. lupulus L. (hops) as two economically important crops.

These two plants have been used by humans for many purposes including as a fiber, food, medicine, or inebriant in the case of C. sativa, and as a flavoring component in beer brewing in the case of H. lupulus.

In this study, we report the complete chloroplast genomes for two distinct hemp varieties of C. sativa, Italian “Carmagnola” and Russian “Dagestani”, and one Czech variety of H. lupulus “Saazer”.

Both C. sativa genomes are 153 871 bp in length, while the H. lupulus genome is 153 751 bp. The genomes from the two C. sativa varieties differ in 16 single nucleotide polymorphisms (SNPs), while the H. lupulus genome differs in 1722 SNPs from both C. sativa cultivars.”

The Genetic Structure of Marijuana and Hemp.

“Despite its cultivation as a source of food, fibre and medicine, and its global status as the most used illicit drug, the genus Cannabis has an inconclusive taxonomic organization and evolutionary history.

Drug types of Cannabis (marijuana), which contain high amounts of the psychoactivecannabinoid Δ9-tetrahydrocannabinol (THC), are used for medical purposes and as a recreational drug.

Hemp types are grown for the production of seed and fibre, and contain low amounts of THC.

Two species or gene pools (C. sativa and C. indica) are widely used in describing the pedigree or appearance of cultivated Cannabis plants.

Using 14,031 single-nucleotide polymorphisms (SNPs) genotyped in 81 marijuana and 43 hemp samples, we show that marijuana and hemp are significantly differentiated at a genome-wide level, demonstrating that the distinction between these populations is not limited to genes underlying THC production.

We find a moderate correlation between the genetic structure of marijuana strains and their reported C. sativa and C. indica ancestry and show that marijuana strain names often do not reflect a meaningful genetic identity.

We also provide evidence that hemp is genetically more similar to C. indica type marijuana than to C. sativa strains.”

Denaturation and Oxidative Stability of Hemp Seed (Cannabis sativa L.) Protein Isolate as Affected by Heat Treatment.

“The present study investigated the impact of heat treatments on the denaturation and oxidative stability of hemp seed protein during simulated gastrointestinal digestion (GID).

Heat-denatured hemp protein isolate (HPI) solutions were prepared by heating HPI (2 mg/ml, pH 6.8) to 40, 60, 80 and 100 °C for 10 min. Heat-induced denaturation of the protein isolates was monitored by polyacrylamide gel electrophoresis. Heating HPI at temperatures above 80 °C significantly reduced solubility and led to the formation of large protein aggregates. The isolates were then subjected to in vitro GID and the oxidative stability of the generated peptides was investigated. Heating did not significantly affect the formation of oxidation products during GID.

The results suggest that heat treatments should ideally remain below 80 °C if heat stability and solubility of HPI are to be preserved.”

Evaluation of Serum Cytokines Levels and the Role of Cannabidiol Treatment in Animal Model of Asthma.

Image result for hindawi

“Asthma represents a public health problem and traditionally is classified as an atopic disease, where the allergen can induce clinical airway inflammation, bronchial hyperresponsiveness, and reversible obstruction of airways.

Studies have demonstrated the presence of T-helper 2 lymphocytes in the lung of patients with asthma. These cells are involved in cytokine production that regulates immunoglobulin synthesis.

Recognizing that T cell interaction with antigens/allergens is key to the development of inflammatory diseases, the aim of this study is to evaluate the anti-inflammatory potential of cannabidiol (CBD) in this setting.

CBD treatment was able to decrease the serum levels of all analyzed cytokines except for IL-10 levels.

CBD seems to be a potential new drug to modulate inflammatory response in asthma.” http://www.ncbi.nlm.nih.gov/pubmed/26101464

“In conclusion, we here demonstrate that the administration of CBD in an animal model of asthma could blunt the serum cytokine response to OVA in sensitized animals. These effects suggest a potential for a new asthma treatment since CBD controls the exaggerated inflammatory response observed in this model.” https://www.hindawi.com/journals/mi/2015/538670/

Cardioprotective effect of cannabidiol in rats exposed to doxorubicin toxicity.

“The potential protective effect of cannabidiol, the major non-psychotropic Cannabis constituent, was investigated against doxorubicin cardiotoxicity in rats.

Histopathological examination showed that cannabidiol ameliorated doxorubicin-induced cardiac injury.

Immunohistochemical analysis revealed that cannabidiol significantly reduced the expression of inducible nitric oxide synthase, nuclear factor-κB, Fas ligand and caspase-3, and increased the expression of survivin in cardiac tissue of doxorubicin-treated rats.

These results indicate that cannabidiol represents a potential protective agent against doxorubicin cardiac injury.”

Cannabidiol, a nonpsychoactive Cannabis constituent, protects against myocardial ischemic reperfusion injury

Heart and Circulatory Physiology

“CANNABINOIDS ARE NATURAL and synthetic compounds structurally or pharmacologically related to the constituents of the plant Cannabis sativa or to the endogenous agonists (endocannabinoids) of the cannabinoid CB1 and CB2 receptors.

Cannabidiol (CBD) is a major cannabinoid constituent of Cannabis.

In contrast to tetrahydrocannabinol, CBD binds very weakly to CB1 and CB2 receptors. Contrary to most cannabinoids, CBD does not induce psychoactive or cognitive effects.

CBD has been shown to have anti-inflammatory properties. CBD (together with tetrahydrocannabinol) has been successfully tested in a few preliminary human trials related to autoimmune diseases…

Cannabidiol (CBD) is a major, nonpsychoactive Cannabis constituent with anti-inflammatory activity mediated by enhancing adenosine signaling.

Inasmuch as adenosine receptors are promising pharmaceutical targets for ischemic heart diseases, we tested the effect of CBD on ischemic rat hearts.

Our study shows that CBD induces a substantial in vivo cardioprotective effect from ischemia that is not observed ex vivo.

Inasmuch as CBD has previously been administered to humans without causing side effects, it may represent a promising novel treatment for myocardial ischemia.”

Effect of dietary hempseed intake on cardiac ischemia-reperfusion injury.

Regulatory, Integrative and Comparative Physiology

“Polyunsaturated fatty acids (PUFAs) have significant, cardioprotective effects against ischemia.

Hempseed contains a high proportion of the PUFAs linoleic acid (LA) and alpha-linolenic acid (ALA),

Hearts from rats fed a hempseed-supplemented diet exhibited significantly better postischemic recovery of maximal contractile function and enhanced rates of tension development and relaxation during reperfusion than hearts from the other groups.

Our data demonstrate that dietary hempseed can provide significant cardioprotective effects during postischemic reperfusion. This appears to be due to its highly enriched PUFA content.”  http://www.ncbi.nlm.nih.gov/pubmed/17122327

“Polyunsaturated fatty acids (PUFAs) have received special research attention because of their antiarrhythmic and cardioprotective effects in hearts challenged by an ischemia-reperfusion insult. There are two major types of PUFAs: omega-3 and omega-6. Linoleic acid (LA) and α-linolenic acid (ALA) are common examples of an omega-6 and an omega-3 fatty acid, respectively… We have demonstrated for the first time in this study that dietary hempseed represents an effective, unique method to significantly alter the levels of ALA in the heart. We have also demonstrated for the first time that dietary hempseed will confer beneficial cardioprotective effects in hearts subjected to ischemia-reperfusion challenge.”  http://ajpregu.physiology.org/content/292/3/R1198
