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 ...

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.

Biodegradation and disintegration of expanded polystyrene by land snails Achatina fulica

Science of The Total Environment, 2020
Despite increasing evidence of widespread plastic pollution in soil, it remains largely unknown about the fate of plastic influenced by soil animals. In this study, ingestion and biodegradation capability of expanded polystyrene (PS) foam was investigated in a globally distributed soil invertebrate, Achatina fulica. After 4-week exposure, 18.5 ± 2.9 mg

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.

Effects of procaine on a central neuron of the snail, Achatina fulica Ferussac

Life Sciences, 2005
Effects of procaine on a central neuron (RP1) of the giant African snail (Achatina fulica Ferussac) were studied pharmacologically. The RP1 neuron showed spontaneous firing of action potential. Extra-cellular application of procaine (10 mM) reversibly elicited bursts of potential.

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 (

Different Glycosubstances and Galactans in the Albumin Gland and Eggs of Achatina fulica

Zeitschrift für Immunitätsforschung: Immunobiology, 1976
In saline extracts from the eggs and the albumin gland of the snail Achatina fulica 3 different forms of glycosubstances have been found by using heterophile precipitins from different sources: 1. An alkali-stable galactan reacting with the anti-galactans from Axinella polypoides sponge and from the clam Tridacna maxima (Tridacnin) and with ...
