    Vascular actions of neurohypophysial peptides in the flounder

    Free swimming, chronically cannulated flounder have been used to study the blood pressure effects of arginine vasotocin (AVT) and isotocin. The initial fall in dorsal aortic blood pressure following AVT inject...

    Pituitary and plasma AVT content in the flounder (Platichthys flesus)

    Radioimmunoassay measurement of pituitary AVT content and plasma AVT concentration indicated comparable levels in fully adapted sea water (SW) and fresh water (FW) flounders. Circulating AVT represented less t...

    The steroidogenic response to angiotensin II in the Australian lungfish, Neoceratodus forsteri

    Corticosterone, aldosterone and cortisol were found to be present in lungfish plasma. Plasma levels of these hormones were measured in lungfish following separate single intramuscular injections of three forms...

    Arginine vasotocin and fish osmoregulation

    Pituitary arginine vasotocin (AVT) secretion is sensitive to the osmotic challenge associated with transfer of euryhaline teleosts between sea water (SW) and fresh water (FW). Pituitary AVT content in FW-adapt...

    Drinking behaviour in sea water and fresh water teleosts, the role of the renin-angiotensin system

    Basal drinking rate and responses to administered angiotensin were examined in 12 species of fish. The responses of representative euryhaline, stenohaline marine and fresh water species to pharmacological mani...

    Biological actions of atrial natriuretic factor in flatfish

    Flounder adapted to seawater were chronically cannulated and received a single i.v. injection of either saline (control) or 10 µg/kg b.w. of human ANF. Compared to controls, ANF significantly reduced (p<0.001)...
