Abstract

The contents of endogenous noradrenaline (NA) in rabbit gingiva and dental pulp were approximately 15-fold greater than either adrenaline (A) or dopamine (DA). Whereas catecholamine contents of maxillary incisor pulps were similar to those in mandibular incisor pulps, variations existed between gingiva excised from different regions. Both reserpine pretreatment and chronic sympathetic denervation greatly decreased the NA contents. These findings support the view that NA is the sympathetic neurotransmitter in dental pulp and gingiva.

摘要

兔牙龈和牙髓中内源性去甲肾上腺素（NA）的含量比肾上腺素（A）或多巴胺（DA）高出约15倍。而上颌切牙髓中的儿茶酚胺含量与下颌切牙髓中的相似，但不同区域切除的牙龈之间存在差异。利血平预处理和慢性交感神经去支配均大大降低了NA含量。这些发现支持了NA是牙髓和牙龈中交感神经递质的观点。
