Anti-inflammatory effects of an aqueous extract of Welsh onion green leaves in mice.

The anti-inflammatory effects of an aqueous extract of Welsh onion green leaves (WOE) in mice was investigated. Administration of WOE, in the range of 0.25-1g/kg, showed a concentration dependent inhibition on paw edema development after carrageenan treatment in mice.

Spermine-graft-dextran non-covalent copolymer as coating material in separation of basic proteins and neurotransmitters by capillary electrophoresis.

Spermine-graft-dextran (Spe-g-Dex) copolymer was synthesized and used as a non-covalent coating for the separation of proteins and neurotransmitters by capillary electrophoresis. The coating was obtained via flushing the capillary with 1.0% Spe-g-Dex copolymer solution for 2min.

Effects of exogenous polyamines on growth, toxicity, and toxin profile of dinoflagellate Alexandrium minutum.

The effect of exogenous polyamines (cadaverine, putrescine, norspermidine, spermidine, and spermine) on the growth, toxicity, and toxin profile of the dinoflagellate Alexandrium minutum T1 was examined. It was found that cadaverine at concentrations of 0.1-2.

Paralytic toxins in three new gastropod (Olividae) species implicated in food poisoning in southern Taiwan.

The toxins in the new gastropods Oliva miniacea, O. mustelina and O. nirasei implicated in a food paralytic poisoning incident in South Taiwan in February 2002 were studied.

Tetrodotoxin-associated snail poisoning in Zhoushan: a 25-year retrospective analysis.

Outbreaks of paralytic snail poisoning have recently occurred in Asia, especially in China. The epidemiological characteristics of this disease from an outbreak in Zhoushan City, China, were recorded. Forty-two outbreaks of paralytic snail poisoning, involving 309 cases of illness, occurred from 1977 to 2001.

Effects of toxic dinoflagellates and toxin biotransformation in bivalves.

Attempts were made to elucidate the different responses of shellfish to paralytic shellfish poison (PSP) and the PSP donor Alexandrium minutum T1. Five species of edible bivalves (Crassostrea gigas, Meretrix lusoria, Mytilus edulis, Ruditapes philippinarum, and Soletellina diphos) were collected and examined for susceptibility to PSP and PSP donor. It was determined that all five bivalves had low susceptibility to PSP following an intramuscular injection (> 300 MU/20 g).

Tetrodotoxin in gastropods (snails) implicated in food poisoning in Northern Taiwan.

The toxin in the gastropods (snails) Zeuxis sufflatus and Niotha clathrata implicated in a food poisoning incident in northern Taiwan in April 2001 was studied. The symptoms exhibited by four victims were general paresthesia, paralysis of the phalanges and the extremities, paralysis, coma, vomiting, and aphasia. The remaining gastropods were assayed for toxicity in the form of tetrodotoxin (TTX).
