【Abstract】

<正>Morphological and pharmacological studies have demonstrated the presence of functional sympathetic-parasympathetic interaction in regulating cerebral vascular tone. Activation by nicotine of sympathetic nerves results in release of norepinephrine which then diffuses to act on presynapticβ2-adrenoceptor located on the neighboring nitrergic nerve terminals to release nitric oxide (NO) causing vasodilation. On the other hand, acetylcholine released in cerebral
