Abstract:AIM: To investigate the inhibitory effect of dihydro- β -erythroidine on nicotine induced- current in cultured superior cervical ganglion of neonatal rats.METHODS: Pneumatic pressure administration of drug and whole- cell recording techniques were performed to compare induced- current amplitude.RESULTS: Dihydro- β - erythroidine competitively antagonized nicotinic effect,and EC50 was about 0.015mmol/L.CONCLUSION: Dihydro- β - erythroidine is a competitive antagonist of nicotinic receptors in sympathetic neurons.
Keywords:whole-cell recording  induced-current  dihydro-β-erythroidine  superior cervical ganglion cell  nicotinic receptor  competitive antagoni?
