Some aspects of cholinergic mechanisms on the isolated chicken oesophagus and crop
SP Verma, SK Garg, BD Garg
Carbamylcholine and acetylcholine produced concentration dependent contractions of isolated chicken oesophagus and crop. Oesophagus was found to be more sensitive than crop. PA2 values of atropine against acetylcholine were found to be 9.40 and 11.20 on oesophagus and crop, respectively. The contractile response to acetylcholine was also effectively antagonized by promethazine and cyproheptadine, suggesting interactions amongst cholinergic, histaminergic and tryptaminergic mechanisms.
