Animal grouping, administration and sample collection 5 days after injection of Methyl mercury chloride (5. 0mg/kg) , 42 adult male mice were randomly assigned into four groups: the ini-tial, 0.0, 0. 3 and 3. 0mg/kg acivicin groups. 受试小鼠一次腹腔注射氯化甲基汞，剂量为5.
The richer sympathetic innervation in the submandibular glands of the adult male mice is evidently related to the greater development of their convoluted tubules whose cells manufacture NGF. 成年雄性小鼠的领下腺内有较丰富的交感神经末梢，显然与成年雄性小鼠的领下腺有高度分化的卷曲小管，产生大量的神经生长因子(NGF)有关。
