Preterm lamb response to changes in blood pressure.

SCG = superior cervical ganglion, BC = Brachiocephalic artery, NE = norepinephrine, AT II = angiotensin 2, CBF = cerebral blood flow.All interventions resulted in significant changes from baseline.All blood pressure and CBF changes after unilateral SCG removal did not differ significantly from pre-SCG removal responses (t-test for blood pressure, 1-way ANOVA for CBF).本研究涉及的缩写定义如下：SCG（superior cervical ganglion，颈上神经节）、BC（Brachiocephalic artery，头臂动脉）、NE（norepinephrine，去甲肾上腺素）、AT Ⅱ（angiotensin 2，血管紧张素Ⅱ）以及CBF（cerebral blood flow，脑血流量）。所有干预措施均使观测指标相较于基线水平产生显著变化。单侧颈上神经节切除术后的血压与脑血流量变化，与颈上神经节切除前的对应反应无显著差异（血压比较采用t检验，脑血流量比较采用单因素方差分析）
