Effect of electroacupuncture on nos expression in locus ceruleus in rats 电针对大鼠蓝斑一氧化氮合酶阳性神经元表达的影响
2.
Methods : hyperosmotic pressure animal model was established by administering 3 % sodium chloride as drinking water to rats or increasing osmotic pressure of the culture medium . osmoregulation positions in the brain , reciprocal projection pathways between the medullary visceral zone ( mvz ) and supraoptic nucleus ( son ) or hypothalamic paraventricular nucleus ( pvn ) , oscillation of intracellular calcium in cultured neurons and astrocytes were studied by means of anti - fos , glial fibrillary acidic protein ( gfap ) , tyrosine hydroxylase ( th ) or vasopressin ( vp ) multiple imrnunohistochemical staining , immuno - electronic microscope , wga - hrp retrogradely tracing and cell culture methods . results : ( 1 ) fos positive neurons within the mvz , parabrachial nuclei , locus ceruleus , pvn , son , subfomical organ increased markedly 方法：通过给予大鼠饮用3氯化钠或提高培养基渗透压浓度的方法复制高渗刺激模型，主要采用抗fos 、胶质原纤维酸性蛋白( gfap )和酪氨酸羟化酶( th ) (或加压素? vp )免疫组织化学多重染色、免疫电镜、 wga - hrp束路追踪结合免疫组织化学多重染色、细胞培养等实验方法，系统观察了中枢参与渗透压反射的调控部位、下丘脑视上核( son )神经元? ast超微结构的变化、延髓内脏带( mvz )和son及下丘脑室旁核( pvn )之间往返投射通路和神经元的性质及其与ast的关系、培养神经元和ast内钙波的变化。
