Fig. 6From: The in vitro effect of delta-9-tetrahydrocannabinol and cannabidiol on whole blood viscosity, elasticity and membrane integritya Blood film of cells exposed to 50 ng/ml cannabidiol (CBD). Blood film showing red cell changes in 50 ng/ml CBD: burr cell formation (echinocytes). Scale = 100 μm (red arrow indicates burr cells; green arrow indicates blister cells, while the yellow arrow indicates extruded cytoplasm). b Blood film of cells exposed to 50 ng/ml delta-9-tetrahydrocannabinol (THC). Blood film showing red cell changes in 50 ng/ml THC: target cell formation, burr cells. Scale = 100 μm (red arrow indicates burr cells; green arrow indicates blister cells, while the yellow arrow indicates extruded cytoplasm)Back to article page
