Production of tetrodotoxin in puffer fish embryos.
It has been accepted that puffer fish accumulates tetrodotoxin through the food chain. This indicates that tetrodotoxin in puffer fish is exogenous. The present study, however, describes an endogenous origin of tetrodotoxin in puffer fish. For this purpose, the ovulated oocytes from puffer fish Fugu niphobles were artificially fertilized and cultivated. The toxin levels of embryos increased gra...
متن کاملRemoval of Toxin (Tetrodotoxin) from Puffer Ovary by Traditional Fermentation
The amounts of puffer toxin (tetrodotoxin, TTX) extracted from the fresh and the traditional Japanese salted and fermented "Nukazuke" and "Kasuzuke" ovaries of Takifugu stictonotus (T. stictonotus) were quantitatively analyzed in the voltage-dependent sodium current (I(Na)) recorded from mechanically dissociated single rat hippocampal CA1 neurons. The amount of TTX contained in "Nukazuke" and "...
متن کامل[Analysis of tetrodotoxin in puffer-fish by LC/MS].
A simple and reliable method using liquid chromatography/electrospray ionization-mass spectrometry (LC/ESI-MS) for the analysis of tetrodotoxin in puffer-fish was developed. Tetrodotoxin in puffer-fish was extracted with 0.1% acetic acid by heating in a boiling water bath, and the extracts were cleaned up on a Bond Elut C18 (500 mg) cartridge. The LC separation was performed on a TSK-gel ODS 80...
متن کاملToxic Marine Puffer Fish in Thailand Seas and Tetrodotoxin They Contained
A total of 155 puffers caught from two of Thailand's seas, the Gulf of Siam and the Andaman seas, during April to July 2010 were included in this study. Among 125 puffers from the Gulf of Siam, 18 were Lagocephalus lunaris and 107 were L. spadiceus which were the same two species found previously in 2000-2001. Thirty puffers were collected from the Andaman seas, 28 Tetraodon nigroviridis and tw...
متن کاملBiological Activities of Tetrodotoxin-Producing Enterococcus faecium AD1 Isolated from Puffer Fishes
Puffer fishes were collected from the central sea in Vietnam from spring to summer season. The eggs were incubated in MRS broth that was used to test the toxicity in mice and isolate the lactic acid bacteria community that could produce tetrodotoxin (TTX). Thin layer chromatography (TLC) and high performance lipid chromatography (HPLC) were used to detect and quantify TTX. As a result, Enteroco...
