... to 12‰ saltwater for 5 weeks to determine the effects of chronic exposure to saline environments. Following 5 weeks, plasma levels of hormones [e.g. progesterone, testosterone, estradiol, corticosterone, aldosterone (ALDO), angiotensin II (ANG II)] were quantified using liquid chromatography and tandem...

...), and cortisol treatment significantly increased transepithelial resistance (TER) and decreased paracellular [ 3 H]PEG-4000 flux. Epithelial permeability was unaffected by deoxycorticosterone or aldosterone. The GR antagonist RU486 as well as MR antagonists spironolactone and RU26752 significantly reduced...

... of metyrapone, blocking cortisol receptors through exposure to either RU-486 (GR antagonist) and spironolactone (MR antagonist), or through exogenous infusion of the tetrapod mineralocorticoid aldosterone (tetrapod MR agonist). The data demonstrate that lowering the activity of cortisol, either by inhibiting...

... in aldosterone concentration during hypercapnia and a possible accompanying increase in corticosterone. The results suggest that the compensatory response to hypercapnia in larval A. tigrinum involves alterations in cutaneous ion transport which increase the extracellular SID. These cutaneous responses may...
