用抗甲壳类β-色素分散激素（PDH）的抗血清，研究了PDH样免疫反应阳性神经元在腹足类螺类（H. pomatia）和滞水螺（E. stagnalis）中枢神经系统的分布和化学神经解剖。发现螺旋中枢神经系统中的免疫反应细胞数量较多（700-900个），而在椎实蝇中，只有有限数量（50-60个）的神经元表现出免疫反应性。免疫组化结果显示，中枢神经节内神经元呈树枝状分布，周围神经及周围神经干周围有大量的神经（结缔组织）鞘分布。内脏-顶叶神经节复合体中的少数受阻神经细胞体也被PDH样免疫反应过程支配。因此，一个复杂的中央和外周的监管作用，包括神经激素的行动，建议PDH样物质在Hebrasia，而网站的行动可能是更有限的，在Arabnaea。
By using an antiserum raised against a crustacean beta-pigment-dispersing hormone (PDH), the distribution and chemical neuroanatomy of PDH-like immunoreactive neurons was investigated in the central nervous system of the gastropod snails, Helix pomatia and Lymnnea stagnalis. The number of immunoreactive cells in the Helix central nervous system was found to be large (700-900), whereas in Lymnaea, only a limited number (50-60) of neurons showed immunoreactivity. The immunostained neurons in Helix were characterized by rich arborizations in all central ganglia and revealed massive innervation of all peripheral nerves and the neural (connective tissue) sheath around the ganglia and peripheral nerve trunks. A small number of Helix nerve cell bodies in the viscero-parietal ganglion complex were also found to be innervated by PDH-like immunoreactive processes. Hence, a complex central and peripheral regulatory role, including neurohormonal actions, is suggested for a PDH-like substance in Helix, whereas the sites of action may be more limited in Lymnaea.
