Abstract/OtherAbstract:
|
Gamma-aminobutyric acid (GABA) blocked concentration of the pigments in melanophores and erythrophores of intact crabs. GABA blocked the release of pigment concentrating hormones from the isolated eyestalk. Octopamine (OA) blocked black pigment dispersion in intact crabs, but did not affect red pigment dispersion or concentration. OA blocked the release of black pigment dispersing hormone from isolated eyestalks. Met-enkephalin, but not Leu-enkephalin, stimulated black and red pigment concentration in intact crabs. Met-enkephalin, but not Leu-enkephalin, stimulated the release of pigment concentrating hormones from isolated eyestalks. Naloxone blocked the effects of Met-enkephalin in intact crabs and on isolated eyestalks. Beta-endorphin induced black pigment dispersion in intact crabs and in isolated legs. |
