  1. 01LabEx vivo tissueActivity measurement

    In frog glomeruli, oxytocin ranked above arginine vasopressin and DDAVP, and below arginine vasotocin and several antagonists, in recognition by vasotocin receptors.

    In plain wordsIn frog kidney tissue, oxytocin was recognised by vasotocin receptors less well than vasotocin but better than vasopressin.

    Summary
    Glomerular receptors exhibited the following stereospecificity for recognition of vasotocin analogues: Tyr-NH2(9)-LA-V1a > 125I-OVTA > arginine vasotocin (AVT) > or = [d(CH2)5Tyr-(Me)2]AVP > OVTA > or = [Phe2,Orn8]VT > oxytocin (OT) > or = [d(CH2)5-Sar7]AVP > desGly9[d(CH2)5Tyr(Et)2]VAVP > or = [d(C…

    Summary · context
    Vasotocin receptors were investigated in glomeruli and nephron segments microdissected from collagenase-treated kidneys of Rana ridibunda, using [d(CH2)5Tyr(Me)2,Thr4,Orn8,125I-Tyr-NH2(9)]vasotocin (125I-OVTA) as a radioligand.
  2. 02LabEx vivo tissueActivity measurement

    In frog glomeruli, oxytocin stimulated phosphoinositidase C less than [Phe2,Orn8]VT and arginine vasotocin and more than arginine vasopressin and DDAVP.

    In plain wordsIn frog kidney tissue, oxytocin switched on an enzyme less than vasotocin did but more than vasopressin did.
