The following review of literature regarding the pharmacology of marijuana is intended to demonstrate its mental and physical pharmacological effects. "Marijuana" refers specifically to the dried leaves and flowering tops or "herbal cannabis”, the natural form of cannabis as derived from the plant Cannabis sativa. Another term for marijuana is the word cannabis or hemp.

Background: Urinary cannabinoid excretion and immunoassay performance were evaluated by semiquantitative immunoassay and gas chromatography–mass spectrometry (GC/MS) analysis of metabolite concentrations in 4381 urine specimens collected before, during, and after controlled oral administration of tetrahydrocannabinol (THC). Methods: Seven individuals received 0, 0.39, 0.47, 7.5, and 14.8 mg THC...

aminopeptidase [EC 3,4,11.1] from a plant source was rare.2'6) The cDNA sequence of a leucine aminopeptidase, which is an inducible component of the defense response in Io,copersicon esculentum, has been analyzed,'} and the enzymatic characteristics of this aminopeptidase have been studied.S} During screening for aminopeptidases from plant sources by using Leu:pNA as a substrate, we found a new...

Materials Research Group (CMRG) at the University of Mississippi (UM) have recently begun a research study supported by the U. S. Department of Agriculture (NRICSREES-USDA Award number 2003-35504-13627) examining natural fiber reinforcements (NFR). The objectives of this research are to demonstrate the feasibility of using the cost-effective pultrusion process to manufacture high quality polyme...

Comparative studies were conducted on mycelial preparations of the bioherbicide, Myrothecium verrucaria (MV) strain IMI 361690 and a recently discovered sector (MV-Sector BSH) of this fungus. The whitish sector was discovered, isolated, grown in pure culture on PDA and found to be a stable, non-spore producing mutant when cultured over several months under conditions that cause circadian sporul...

Forty-eight 19-wk-old Bovan White laying hens were fed 1 of 5 diets containing either hemp seed (HS) or hemp seed oil (HO). The level of HO was 4, 8, or 12%, whereas the level was 10 or 20% for the HS. A set of 8 birds fed wheat-, barley-, and corn oil-based diets served as the control. Performance was monitored over 12 wk. Average hen-day egg production was not affected upon feeding of either ...

The risk of developing multiple sclerosis (MS) is associated with increased dietary intake of saturated fatty acids. For many years it has been suspected that this disease might be associated with an imbalance between unsaturated and saturated fatty acids. We determined erythrocyte membrane fatty acids levels in Hot nature dietary intervention with co-supplemented hemp seed and evening primrose...

Cover crops are a major focus of conservation agriculture efforts because they can provide soil cover and increase nutrient availability after their mineralization in cropping systems. To evaluate the effect of residue type and placement on rate of decomposition and carbon (C) and nitrogen (N) mineralization, residues from two food crops, maize (Zea mays L.) and common bean (Phaseolus vulgaris ...

Hemp (Cannabis sativa) stalk fibres from industry residues were incorporated into polybutylene adipate terephthalate, a synthetic biodegradable polyester, to produce films and paper coatings. The lignocellulosic components the chemical composition of analysed, results highlight bioactivity due cannabinoids, alkanoids, lignin, among others, making attractive for active food packaging. incorporat...

This research is aimed at seeing how different stacking sequences and chemical treatments impact the mechanical characteristics of ramie–hemp composites. Hand-lay-up procedures were used to create a blend woven ramie hemp fibers. The was treated with diluted 6% sodium hydroxide (NaOH) solution compare properties preserved unpreserved hybrid According findings, tensile composites are better in t...
