Distribution and speciation of cadmium in the terrestrial snail,Helix aspersa
Bulletin of Environmental Contamination and Toxicology, 1979Cadmium is taken up by terrestrial snails living in an environment with a relatively high cadmium concentration. The metal becomes bound to protein with a molecular weight of approximately 22,000 daltons. This cadmium-protein complex concentrates in the digestive gland and is present in a form which is soluble in water, (though difficult to extract ...

Tyrosine hydroxylase in snail (Helix pomatia) nervous tissue
Biochemical Pharmacology, 1976Abstract Snail nervous tissue synthesizes [14]dopamine and [14]dihydroxyphenylalanine (DOPA) from [14C]tyrosine. The Km value for the overall conversion of [14C]dopamine was 6 × 10−4M. The enzyme converting [14C]tyrosine to [14C]DOPA. tyrosine hydroxylase, has the following characteristics.

Calcium mobilisation during reproduction in snail Helix aspersa
Nature, 1977THE land snail Helix aspersa lays up to 100 eggs at a time, each with 0.6 mg of calcium in the form of calcite crystals. There is insufficient calcium in any part of the reproductive tract to account for this.

The fine structure of the myofibers in the heart of the snail Helix aspersa
Journal of Ultrastructure Research, 1963The ultrastructure of the myofibers in the heart of a mollusk is described. Two types of myofilaments are seen in the A-band. The Z-band material is fragmentary and results in small myofibrils. There is a well-represented sarcotubular system, and parts of it appear to be associated with the Z-band material and the sarcolemma.

The Helix aspersa (brown garden snail) allergen repertoire.
International archives of allergy and immunology, 2005Ingestion of snails can induce strong asthmatic or anaphylactic responses, mainly in house-dust-mite-sensitized patients. The aim of this study was to identify the Helix aspersa (Hel a), Theba pisana (The p) and Otala lactea (Ota l) allergens and the extent of their cross-reactivity with the Dermatophagoides pteronyssinus (Der p) mite.In 60 atopic ...
