1。突触前肾上腺素受体亚型在人的作用研究是基于观察血压的变化(δBP)和血浆去甲肾上腺素浓度(δNA)冷加压试验(CPT)。2。的CPT是可再生的BP和NA在2周的时间间隔执行时轻度高血压患者。3所示。政府4周后,胍法辛(女朋友;阿尔法2-adrenoceptor受体激动剂)减少三角洲NA对CPT的回应。4所示。政府2或4周后,bunazosin (Bu;阿尔法1-adrenoceptor拮抗剂)阿替洛尔(; beta 1-adrenoceptor antagonist) and nadolol (Nd; non-selective beta-adrenoceptor antagonist) did not affect the delta NA response to CPT. 5. Both Gf and Bu decreased the systolic blood pressure response (delta SBP) to CPT after 4 weeks of the administration. Neither At nor Nd significantly changed the delta SBP response to CPT. 6. It is likely that Gf stimulated the presynaptic alpha 2 adrenoceptors at the sympathetic nerve endings as well as the central alpha 2 adrenoceptors, inhibiting the release of noradrenaline. It is unlikely that Bu, At and Nd exerted any clearly defined action on the presynaptic adrenoceptors in human hypertensive subjects.
