OBJECTIVE
To determine the transcorneal flux, and intracorneal penetration, of Delta9-tetrahydrocannabinol when presented to the isolated rabbit cornea in different vehicles.
METHODS
Corneas were mounted in specular microscope chambers, with ( 3)H-Delta9-tetrahydrocannabinol on the epithelial
Arachidonic acid, a fatty acid component of neuronal cell membranes, forms the backbone of endogenous ligands of the endocannabinoid system. The lipid nature of this system may make it particularly susceptible to changes in fat content of the diet, which may, in turn, affect endocannabinoid tone and
Rats' performance on a progressive-ratio schedule maintained by sucrose (0.6M, 50 μl) and corn oil (100%, 25 μl) reinforcers was assessed using a model derived from Killeen's (1994) theory of schedule-controlled behaviour, 'Mathematical Principles of Reinforcement'. When the rats were maintained at
The effect of acute (1 day) or subchronic (25 days) treatment with delta 9-tetrahydrocannabinol (THC), the major psychoactive constituent of marihuana, on plasma norepinephrine (NE), epinephrine (E), corticosterone, beta-endorphin (beta-end), and splenic natural killer (NK) cell activity of the rat
delta 9-Tetrahydrocannabinol (delta 9-THC) was studied for potential carcinogenicity in rodents because it is the principal psychoactive ingredient in marihuana and it has potential medicinal uses. delta 9-THC in corn oil was administered by gavage to groups of male and female Fischer rats and
The gestational and adolescent periods are critically important for brain development and exposure to Δ9‑tetrahydrocannabinol (Δ9-THC) during these periods results in long term behavioral and biochemical abnormalities in laboratory animals. However, recent reports indicate a dramatic rise in oral
1-Trans-delta(9)-tetrahydrocannabinol (THC) was nominated by the National Cancer Institute to the NTP for study because it is the major psychoactive component of marijuana and a widely used Schedule I substance. Male and female F344/N rats and B6C3F1 mice received THC (97% pure) in corn oil by
delta9-Tetrahydrocannabinol (delta9-THC) is capable of modulating a variety of immune responses, but has not been evaluated in models of immune-based diabetes. The objectives of the present study were: (a) to investigate the effect of delta9-THC in an established model of multiple low dose
Delta(9)-tetrahydrocannabinol (Delta(9)-THC) has been widely established as a modulator of host immune responses. Accordingly, the objective of the present study was to examine the effects of Delta(9)-THC on the immune response within the lungs and associated changes in the morphology of the
Introduction: Recent studies have suggested that cannabidiol (CBD) could interconvert into Delta-8- and Delta-9- tetrahydrocannabinol. Materials and Methods: Thus, we tested the plasma samples of 120 healthy human subjects (60 male and 60 female), 60 in fasting and the other 60 under
