Noradrenalin was shown to elicit either constrictory or dilatory responses depending on the initial level of venous pressure (10-15 mm Hg or 0 and 25 mm Hg) in the capacitance vessels of the cat small intestine. Blockade of beta-adrenoreceptors with propranolol has no effect on the capacitance vessels responses. Blockade of alpha-adrenoreceptors with dihydroergotoxin makes noradrenaline to elicit dilatory responses only, their magnitude depending on the initial level of venous pressure: more obvious responses at 10-15 mm Hg, less obvious those - at 0 and 25 mm Hg.
研究表明，去甲肾上腺素会根据猫小肠容量血管中静脉压的初始水平（10 - 15毫米汞柱或0及25毫米汞柱）引发收缩或舒张反应。用普萘洛尔阻断β - 肾上腺素能受体对容量血管的反应没有影响。用二氢麦角毒素阻断α - 肾上腺素能受体后，去甲肾上腺素仅引发舒张反应，其幅度取决于静脉压的初始水平：在10 - 15毫米汞柱时反应更明显，在0及25毫米汞柱时反应较不明显。
