[Accumulation of cyclic adenosine monophosphate in the ovary of the eel (Anguilla anguilla L.) in vitro under the effect of carp gonadotropin or ovine lutropin: kinetics and thermodependence].

Abstract

Cyclic AMP (cAMP) in pieces of eel ovary was greatly increased in vitro by the gonadotropin (cGTH) of carp, another teleost fish; after one hour at 20 degrees C, maximal stimulation = 31.7 and E.D. 50 = 0.08 micrograms/ml. Ovine lutropin (oLH) had less effect (maximal stimulation: 2.35; E.D. 50: 1.42 micrograms/ml); its action suggested that it involved a… (More)
