anemone taipaiensis/癲癇性発作

The crude extract from the sea anemone, Bunodosoma caissarum caused dose-dependent convulsions by i.c.v. route in mice. The involvement of the glutamatergic system in the convulsions was investigated. MK-801 and ketamine, non-competitive NMDA receptor antagonists, prolonged the latencies for

In this study, the behavioral and electroencephalographic (EEG) analysis of seizures induced by the intrahippocampal injection in rats of granulitoxin, a neurotoxic peptide from the sea anemone Bunodosoma granulifera, was determined. The first alterations occurred during microinjection of

A neurotoxic peptide, granulitoxin (GRX), was isolated from the sea anemone Bunodosoma granulifera. The N-terminal amino acid sequence of GRX is AKTGILDSDGPTVAGNSLSGT and its molecular mass is 4958 Da by electrospray mass spectrometry. This sequence presents a partial degree of homology with other

1. Sea anemone toxin II (ATX II) which keeps the activated sodium channels open, can be labelled at its histidine residues with 125I up to a specific radioactivity of 500 Ci/mmole. Upon intraventricular injection in mice, ATX II causes acute, short-lasting hyperexcitation and convulsions. Its LD50

This paper describes two neurotoxic proteins obtained from the Caribbean sea anemone Lebrunia danae. To assess the neurotoxic activity of the venom of L. danae, several bioassays were carried out, and to evaluate the effect of the toxin, Median Lethal Doses (LD(50)) were determined in vivo using sea

The crude as well as partially purified protein fractions from anemone species viz. Heteractis magnifica, Stichodactyla haddoni and Paracodylactis sinensis, collected from the Gulf of Mannar, south east coast of India were found to be toxic at different levels to mice. The mice showed behavioral

The primary structure of cangitoxin (CGX), a 4958 Da peptide from the sea anemone Bunodosoma cangicum, was determined: GVACRCDSDGPTVRGNSLSGTLWLTGGCPSGWHNCRGSGPFIGYCCKK. CGX contains all the 11 residues that are conserved and the 5 that are conservatively substituted within or between the type 1 and
