Effects of Tetra hydro cannabinol to the dendritc tree and synapses of the accumbens nucleus of Wistar rats.
2013
Cannabis is one of the most widely used intoxicants; almost half of all 18
year olds in the USA and in most European countries admit to having tried it
at least once, and ~10% of that age group are regular users.
Δ9-Tetrahydrocannabinol (THC), the principal psychoactive ingredient in
marijuana, produces euphoria and relaxation and impairs motor coordination,
time sense, and short term memory. In the hippocampus, CBs inhibit GABA
release from a subset of interneurons and inhibit glutamate release from
principal neurons. Cannabinoids are reported to produce both rapid and
long-term changes in synaptic transmission. Our study was carried out on ten
male rats out of which brains of six of them were used as the representative
sample for electron microscope analysis, while 4 were used for light
microspcopy performed by Golgi method. Three were exposed to THC and 3 were
controls. Axodendric synapses in the core and shell of the accumbens nucleus
(AN) were studied under electron microscope. The results have shown widening
of the synaptic cleft in the shell of AN. This result is a leading point to
our further investigations which are going to involve a behavioral component,
and different aspects of morphological studies. [Projekat Ministarstva nauke
