Photoperiod and diel variations of serum cortisol, thyroxine and protein in goldfish, Carassius auratus L

Photoperiod and diel variations of serum cortisol, thyroxine and protein in goldfish, Carassius auratus L. Noeske, T.Several substances are used for example 50-23-7 and 51-48-9 which are their cas registry numbers. A.; Spieler, R. E. (Vertebrate Div., Milwaukee Public Mus., Milwaukee, WI 53233, USA). J. Fish Biol., 23(6), 705-10 (English) 1983. CODEN: JFIBA9. ISSN: 0022-1112. DOCUMENT TYPE: Journal CA Section: 12 (Nonmammalian Biochemistry) Goldfish were held for 1 mo on 1 of 4 different photoperiods. In those groups with diel variations of serum cortisol and thyroxine (~60%), the variations were entrained to the photoperiod; peak titers occurred around light onset, min. titers at light offset. Fish held on 2 of the photoperiod regimes had diel variations in serum protein; however, the pattern was not consistent in relation to any aspect of the photoperiod. .

Effects of cortisol and ACTH on gill sodium-potassium ATPase, SDH and chloride cells in juvenile Atlantic salmon Salmo salar L

Effects of cortisol and ACTH on gill sodium-potassium ATPase, SDH and chloride cells in juvenile Atlantic salmon Salmo salar L. Langdon, J. S.; Thorpe, J.In this study， 9002-60-2 and 50-23-7 are also used. E.; Roberts, R. J. (Inst. Aquac., Univ. Stirling, Stirling FK9 4LA, UK). Comp. Biochem. Physiol. A, 77A(1), 9-12 (English) 1984. CODEN: CBPAB5. ISSN: 0300-9629. DOCUMENT TYPE: Journal CA Section: 12 (Nonmammalian Biochemistry) ACTH, but not cortisol, stimulated the gill Na+/K+-ATPase activity of S. salar. Both ACTH and cortisol increased the succinate dehydrogenase (SDH) activity in a suspension of gill cells from presmolts, but not in a homogenate of gill tissue. Neither hormone increased the size or abundance of gill Cl- cells. ACTH caused fin darkening, but neither ACTH nor cortisol induced body silvering. .
