Abstract
  1. The inhibitory effects were studied of 4 beta-adrenoceptor antagonists against renin release induced by isoprenaline (0.5 mumol/1) in rat kidney slices. Additionally the pA2 values of these 4 drugs were measured against isoprenaline in guinea-pig isolated atria and trachea (against beta1- and beta2-adrenoceptors respectively). 2 When employed at a concentration of 2 mumol/1 propranolol and atenolol significantly inhibited renin release (P less than 0.001 and P less than 0.01) whereas practolol and IPS 339 [t-butyl-amino-3 ol-2 propyl) oximino-9 fluorene] had little effect. 2 A positive correlation was shown between the degree of inhibition of renin release and the pA2 of the antagonists at the beta1-adrenoceptors. 4 When practolol and IPS 339 were used in equipotent molar concentrations to propranolol for the beta1-adrenoceptors they inhibited renin release. 5 The results suggest that the adrenoceptor involved in the renin release induced by isoprenaline in the rat kidney is of the beta1-type.
摘要
  1. 研究了4种β-肾上腺素能拮抗剂对异丙肾上腺素(0.5微摩尔/升)诱导的大鼠肾切片肾素释放的抑制作用。此外,还在豚鼠离体心房和气管中(分别针对β1-和β2-肾上腺素能受体)测定了这4种药物对异丙肾上腺素的pA2值。2. 当以2微摩尔/升的浓度使用时,普萘洛尔和阿替洛尔显著抑制肾素释放(P<0.001和P<0.01),而醋丁洛尔和IPS 339 [叔丁基氨基-3-(2-丙基)肟基-9-芴]几乎没有作用。2. 肾素释放的抑制程度与拮抗剂在β1-肾上腺素能受体处的pA2之间呈正相关。4. 当醋丁洛尔和IPS 339以与普萘洛尔等摩尔浓度用于β1-肾上腺素能受体时,它们抑制肾素释放。5. 结果表明,异丙肾上腺素诱导大鼠肾释放肾素所涉及的肾上腺素能受体为β1型。
