Abstract 1. 1. The brown garden snail Helix aspersa Muller, young or adult, takes in and absorbs water orally through its digestive system. 2. 2. During the first month, Helix aspersa is able to absorb 70% of its total weight, in water, daily.

AbstractDistribution, chemical‐neuroanatomy, concentration, and uptake‐release properties of histamine (HA)‐containing neurons and the possible physiological effects of HA in the central and peripheral nervous system of the pulmonate snails,Helix pomatiaandLymnaea stagnalis, are described.

Nervous system and neural maps in gastropodHelix lucorum L.
Neuroscience and Behavioral Physiology, 1994The present review summarizes the literature and provides new data concerning nervous system structure and the identification of individual neurons in the snail Helix lucorum. Information about especially well-known neurons is provided in a table, and maps of the identifiable neuron's location in ganglia are correlated with the results of retrograde ...

A quantitative assay based on real-time detection polymerase chain reaction (rtdPCR) was applied to analyze basal and metal-induced mRNA levels of two metallothionein (MT) isoforms (Cd-MT and Cu-MT) in organs of the terrestrial gastropod Helix pomatia.

Im intakten Penisretraktormuskel-Nerv-Gehirn-Praparat vonHelix pomatia L. treten sowohl tonische als auch phasische Muselkontraktionen auf. Die phasische Kontraktion scheint von peripheren Neuronen gesteuert zu werden, wahrend fur die Steuerung der tonischen Kontraktion zentrale Strukturen eine Rolle spielen.

A proteinase inhibitor with M(r) 697000 and 20.3% (w/w) carbohydrate was isolated from the haemolymph of the snail Helix pomatia and characterized. It was shown to have a tetrameric structure with subunits disulphide linked by two. It inhibited the activity of several types of proteinases against large substrates but not that of trypsin against N-alpha-

Experientia, 1979
The tyrosine is decarboxylated in vitro by the central nervous tissue and by the intracardiac nervous tissue of Helix pomatia by aromatic amino-acid decarboxylase. The tyramine obtained is then partially transformed into octopamine by tyramine-beta-hydroxylase. The inhibition of monoamine oxidase favours apparition of the 2 amines.
