Cannabinoids inhibit cholinergic contraction in human airways through prejunctional CB1 receptors.
BACKGROUND AND PURPOSE Marijuana smoking is widespread in many countries, and the use of smoked synthetic cannabinoids is increasing. Smoking a marijuana joint leads to bronchodilation in both healthy subjects and asthmatics. The effects of Δ(9) -tetrahydrocannabinol and synthetic cannabinoids on human bronchus reactivity have not previously been investigated. Here, we sought to assess the effe...
متن کاملThe effects of 5-HT on cholinergic contraction in human airways in vitro.
Inhaled 5-hydroxytryptamine (5-HT) causes bronchoconstriction in asthmatics, and 5-HT plasma levels are elevated in asthma. Electrical field stimulation (EFS) of human airways, in vitro, evokes cholinergic contraction mediated by the release of acetylcholine (Ach) from postganglionic cholinergic nerves. The present study investigates whether selective 5-HT agonists and antagonists can modulate ...
متن کاملCannabinoids inhibit the respiration of human sperm.
OBJECTIVE To investigate the effects of the psychotropic compounds Delta(9)-tetrahydrocannabinol (Delta(9)-THC) and Delta(8)-tetrahydrocannabinol (Delta(8)-THC) on sperm mitochondrial O(2) consumption (respiration). SETTING State University of New York Upstate Medical University, Syracuse, New York. PATIENT(S) Forty-one men who visited the andrology laboratory for fertility evaluation. IN...
متن کاملEpinastine (WAL 801CL) inhibits the electrical field stimulation-induced cholinergic contraction in guinea pig and human airways in vitro.
Epinastine is an antihistamine drug with binding affinities at 5-hydroxytryptamine (5-HT) receptors. The current study was performed to investigate whether epinastine could modulate the cholinergic contraction in guinea pig and human airways in vitro. Isolated guinea pig and human airway preparations were suspended in organ baths containing modified Krebs-Henseleit solution. Electrical field st...
متن کاملEpinastine (WAL 801CL) modulates the noncholinergic contraction in guinea-pig airways in vitro by a prejunctional 5-HT1-like receptor.
Electrical field stimulation (EFS) of guinea-pig airways, in vitro, evokes an excitatory nonadrenergic noncholinergic (eNANC) contraction mediated by release of tachykinins from sensory nerve endings. Epinastine (WAL 801CL) is an antihistaminic drug with binding affinity at certain other receptors, including alpha-adrenergic receptors and various serotonin (5-HT) receptor subtypes. It is used i...
