The gastrointestinal pharmacology of cannabinoids: focus on motility.

abstract：:In the rabbit, intracerebroventricular administration of dibutyryl cyclic AMP (DBC) produces fever which is selectively antagonised by phenoxybenzamine. This indicates the involvement of central alpha-adrenoceptors in DBC-induced fever. The decrease in DBC hyperthermia after 6-hydroxydopamine (6-OH-DA) supports the vi...
