چکیده

Male albino rats, injected intravenously or intracerebroventricularly with delta 1-tetrahydrocannabinol (THC), develop mudriasis. The median effective dose of the intravenous administration group was 5 mg/kg THC, whereas that for the intracerebroventricular route was 150 microgram/kg THC. Sympathectomy significantly decreased the THC-induced mydriasis. The mydriatic effect was not influenced by naloxone. We conclude that THC produces mydriasis through a central action, the efferent pathway of which is the sympathetic system.

Evaluation of Δ9-tetrahydrocannabinol metabolites and oxidative stress in type 2 diabetic rats

Objective(s): The object of the study is to examine the effects of Δ9-tetrahydrocannabinol (THC) against oxidative stress in the blood and excretion of THC metabolites in urine of type 2 diabetic rats. Materials and Methods: The control (n=8), THC control (n=6), diabetes (n=8) and diabetes + THC (n=7) groups were created. Type 2 diabetes was induced by nicotinamide (NA, 85 mg/kg) + streptozotoc...

Role of cannabinoid receptor type 1 desensitization in greater tetrahydrocannabinol impairment of memory in adolescent rats.

Adolescence is a well defined developmental period during which marijuana use is common. However, little is known about the response to marijuana in adolescents compared with adults. We have shown previously that adolescent rats are more impaired than adults by Δ(9)-tetrahydrocannabinol (THC), the main psychoactive compound in marijuana, in a spatial learning task, but the mechanism responsible...

Δ9-Tetrahydrocannabinol decreases willingness to exert cognitive effort in male rats.

BACKGROUND Acceptance of cannabis use is growing. However, prolonged use is associated with diminished psychosocial outcomes, potentially mediated by drug-induced cognitive impairments. Δ9-Tetrahydrocannabinol (THC) is the main psychoactive ingredient in cannabis, yet other phytocannabinoids in the plant, such as cannabidiol (CBD), have unique properties. Given that CBD can modulate the undesir...

Effects of delta9-tetrahydrocannabinol on reward and anxiety in rats exposed to chronic unpredictable stress.

Although cannabis derivatives produce clear subjective motivational responses in humans leading to drug-seeking behaviour, the reinforcing attributes of these subjective effects are difficult to define in experimental animals. The aim of this study was to examine how exposure to chronic unpredictable stress (CUS) will affect reward function and anxiety after acute administration of Delta(9)-tet...
