Both nurse and lemon sharks recovered slowly from the pressor effect of epinephrine and from the depressor effect of isoproterenol. The recovery time increased with the dose of epinephrine. Grading of dosage and the use of dibenzyline revealed that these species exhibit alpha and beta adrenergic vascular responses in a manner qualitatively similar but quantitatively dissimilar to that for mammals.
护士鲨和柠檬鲨对肾上腺素的升压作用以及异丙肾上腺素的降压作用恢复都很缓慢。恢复时间随肾上腺素剂量增加而延长。剂量分级及使用苄胺唑啉的结果显示,这些物种呈现出的α和β肾上腺素能血管反应,在性质上与哺乳动物相似,但在数量上有所不同。
