Radioligand binding studies suggest that alpha 1-adrenoceptor recognition sites are heterogeneous. Several adrenergic agents discriminate between two adrenoceptor binding sites designated alpha 1A and alpha 1B. In the present study we demonstrate for the first time that these two subtypes

This study investigates the subtypes of the alpha1-adrenoceptor mediating the adrenergically-induced renal vasoconstrictor responses in streptozotocin-induced diabetic and non-diabetic 2-kidney one clip (2K1C) Goldblatt hypertensive rats. The renal blood flow responses to renal nerve stimulation, noradrenaline, phenylephrine, and methoxamine were

The cauda epididymis (CE), the site of sperm storage until the ejaculation, is densely innervated by the sympathetic nervous system. Contraction of CE smooth muscle via α1-adrenoceptors (α1-ARs) plays a key role during the seminal emission phase of ejaculation and

The affinity of 5-methyl-urapidil for alpha 1-adrenoceptors was determined from the inhibition of [3H]prazosin binding on membrane of different rat tissues. In hippocampus, vas deferens and heart 5-methyl-urapidil displaced [3H]prazosin in a biphasic manner with mean pKI values between 9.1
