Multiple forms of the hemocyanin of Achatina fulica

Comparative Biochemistry and Physiology Part A: Physiology, 1971
Abstract Gel filtration of the hemolymph of the snail, Achatina fulica , in a column of Sephadex G-200 equilibrated with 0·025 M Tris-HCl at the same pH value, 8·5, as the hemolymph reveals the presence of at least two forms, A and B, of hemocyanin of different molecular weights which exist in a ratio of 3 : 2 and are not inter-convertible.

Expansion of Achatina fulica in Brazil and potential increased risk for angiostrongyliasis.

Transactions of the Royal Society of Tropical Medicine and Hygiene, 2007
The explosive introduction of the snail Achatina fulica in Brazil illustrates the current concern with global changes favouring dissemination of infectious diseases. The mollusc is an important host for Angiostrongylus cantonensis, which occurs in Asia and the Pacific Islands and is a causative agent for eosinophilic meningoencephalitis.

Structural analysis of a homogeneous polysaccharide from Achatina fulica

International Journal of Biological Macromolecules, 2017
Edible snails have been widely used as a health food and medicine in many countries. In our study, a water-soluble polysaccharide (AF-1) was isolated and purified from Achatina fulica by papain enzymolysis, alcohol precipitation and strong anion exchange chromatography.

A neoplasm in the giant African snail Achatina fulica

Journal of Invertebrate Pathology, 1972
Abstract Gross and histologic descriptions are given for a pedunculate tumor observed in the giant African snail, Achatina fulica. The tumor, situated at the inner juncture of the right tentacle and the dorsal surface of the head, was yellow-white, convered with a film of mucus, and approximately 5–6 mm in diameter.

The olfactory sensitivity of snails,Achatina fulica

Journal of Comparative Physiology ? A, 1982
1. A two-chambered tentacular olfactometer was constructed (Fig. 1). This device permits the local delivery of odors to the tentacular sensory epithelium, with independent control over concentration on the left and right sides. The occurrence of discrete head turns during locomotion, subject to criteria of latency and extent, was indicative of ...

Fulicin regulates the female reproductive organs of the snail, Achatina fulica

Peptides, 2000
Fulicin is a D-amino acid-containing neuropeptide that has been thought to control male copulatory behavior in the land snail, Achatina fulica. In the present study, we demonstrated that the vagina and the oviduct of Achatina were densely innervated by fulicin-like immunoreactive neuronal fibers.

Serological and histochemical studies on the Achatina fulica galactan

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1981
Abstract 1. 1. Glycoconjugates in the albumin glands of Achatina fulica have been fractionated by combination of organic solvents, salt precipitation and chromatography on specific agarose-lectin beads. 2. 2. A galactan consisting only of galactosyl residues was isolated from an agarose peanut-lectin matrix.

Cardioexcitatory neurons in the snail Achatina fulica.

Journal fur Hirnforschung, 1998
The excitatory motor unit of Achatina fulica is composed of five identified cardioregulatory motor neurons: three tonically active neurons (TAN-1, -2 and -3), a periodically oscillating neuron (PON) and a VG1 neuron. High frequency discharges in TAN neurons evoked slow depolarization waves. The PON elicited biphasic excitatory post synaptic potentials (
