Results:①In normal extracellular solution, the non-selective cholinergic agonist acetylcholine and the muscarinic agonist muscarine both caused the increace of [Ca2+]i in separately 21 out of 25 and 14 out of 18 VHCs I, while only 3 out of 20 and 2 out of 16 VHCs I had a weak increase of [Ca2+]i if investigated in calcium free extracellular solution; nicotine could increase the [Ca2+]i in 7 out of 32 VHCsⅠonly at enough high concentration(up to 10 mmol/L) in normal extracellular solution, this [Ca~(2+)]_i increase by nicotine at high concentration could not be investigated if at calcium free solution.
