The effects of intra-arterial injections of serotonin (0.1 nmol kg −1 ) before ( N =11, left panel) and after ( N =8, right panel) treatment with 1 mg kg −1 methysergide (a 5-HT1/5-HT2 receptor antagonist) on cardiovascular parameters (A) and arterial oxygen tension (B...

...Leila V. Virkki; Annika Salama; Mikko Nikinmaa ABSTRACT We have measured the effects of oxygen tension on the transport of Na + , K + and Cl − across the erythrocyte membrane of the lamprey Lampetra fluviatilis . The transport of each ion was affected by the oxygen tension of the medium. Hypoxic...
