In addition to their psychotropic effects, activation of 5-HT2A receptors induces hyperthermia, which could explain this dangerous action of MDMA.

Metabolic acidosis is ac- ratory alkalosis by excreting HCO3 in the urine, thereby, companied on average by a l. Factors which can affect the Hill slope are particularly the presence of more than one population of receptors with different affinities for the agonist contributing to the response (nH 5 1), occurrence of receptor desensitisation (nH 5 1), the presence of more than one agonist binding site on the receptor (as occurs with the ligand-gated ion channel receptors) where more than one site needs to be occupied for efficient activation of the receptor (nH 4 1), and the presence of spare receptors in the tissue (nH 4 1).

Nonetheless, con- ventional radiography is a screening method that may sug- gest the diagnosis, exclude other pathology, and can be correlated with other imaging findings.

It is generally agreed that the periaquaductal grey area (PAG) of the central grey is responsible for eliciting the flight/fight response which incorporates autonomic changes and analgesia as well as the locomotor response.

In on the rate of disappearance of hormone from the blood, its addition to the liver and kidneys, target tissues may take up half-life and MCR can be calculated. In 1984,the term GABAC was introduced to distinguish this third class of GABA receptor (Johnston 1996). To make this possible, sufficient raw data have to be available, which is seldom the case.
