A comparative immunocytochemical investigation of the crustacean hyperglycemic hormone (CHH) in the eyestalks of some decapod crustacea

Abstract The eyestalk of the astacideans Orconects limosus, Nephrops norvegicus , and Homarus gammarus , and the palinuran Palinurus vulgaris , was examined with an antiserum raised against purified crustacean hyperglycemic hormone (CHH) of the astacidean species Astacus leptodactylus .

Description
Summary:Abstract The eyestalk of the astacideans Orconects limosus, Nephrops norvegicus , and Homarus gammarus , and the palinuran Palinurus vulgaris , was examined with an antiserum raised against purified crustacean hyperglycemic hormone (CHH) of the astacidean species Astacus leptodactylus . A distinct immunopositive reaction occurs in a group of neurosecretory cells in the medulla terminalis ganglionic X‐organ (MTGX), in the MTGX‐sinus gland tractus, and in a considerable part of the sinus gland. The immunoreactive sites in the eyestalk of the investigated species correspond to the site of production, storage, and release of the CHH. Preliminary investigations with this antiserum also indicate that a positive immunoreaction can be obtained in the eyestalk of other decapod crustaceans, for example, of the brachyuran Macropipus puber and the caridean Palaemon serratus .
