Hemp ( Cannabis sativa L.) is commonly grown for the medicinal secondary metabolites produced by pistillate inflorescences. Micropropagation a valuable method of propagating hemp plants because aseptic process and production true-to-type propagules. The cultivar TJ’s CBD was used series experiments to compare media inputs practices clonal micropropagation hemp. For stage I, shoot tips harvested...

Most of the cannabinoids in Cannabis sativa L. have not been fully evaluated for their pharmacological activity. A publication in this issue presents evidence that a plant cannabinoid, Delta(9)-tetrahydrocannabivarin is a potent antagonist of anandamide, a major endogenous cannabinoid. It seems possible that many of the non-psychoactive constituents of this plant will be of biological interest.

Edestin, a legumin class reserve protein from hemp seeds having six identical subunits was crystallized from ammonium phosphate at pH 5 and subsequently characterized by X-ray diffraction. The crystals are of space group R32 with a = 127 A and gamma = 116 degrees having an equivalent triply centered hexagonal cell of a = b = 215 A, c = 80 A. There is one hexameric protein in the rhombohedral un...

A protein fraction has been isolated from crude pepsin preparations which is about 400 times as active as crystalline pepsin in the lique-faction of gelatin. The activity as measured by the digestion of casein, edestin or egg albumin is less than that of crystalline pepsin. It is more resistant to alkali than the crystalline pepsin.

Given data showing that cannabis (herbal drug from the Cannabis sativa plant) can impair cognition in healthy subjects, the possibility that it may also do so in people with multiple sclerosis (MS) should be cause for concern. Approximately 20% of people with MS inhale or ingest cannabis for a variety of symptoms, or as a lifestyle choice. In addition, pharmaceutically manufactured cannabis (in...

homelessness are a reality in our daily life." The perception that the government or the ANC should solve all the problems is misplaced. These are complex national problems brought about by decades of deliberate and systematic neglect. For these problems to be addressed effectively we require joint effort by all stakeholders including tertiary institutions.] Clearly the situation as it exists c...
