Electrophoretic analysis of paralytic shellfish toxins

Journal of Environmental Science and Health . Part A: Environmental Science and Engineering, 1977
Abstract Seven paralytic shellfish poisons (PSP) from the dinoflagellate Gonyaulax tamarensis and PSP infested shellfish have been separated by cellulose acetate membrane strip electrophoresis. The acid hydrolysis products of two of these, saxitoxin and neosaxitoxin, are analyzed by electrophoresis.

Botulinum toxin-A in the management of paralytic lagophthalmos

Orbit, 1995
This review discusses the clinical uses of Botulinum toxin-A in the management of patients with orbital disease with particular mention of its role in producing temporary protective ptosis. The actual injection technique is described in detail and there is a brief discussion on its mechanism of action in these patients.

Instrumental Methods for Paralytic Shellfish Toxins

2015
Paralytic shellfish toxins (PSTs) are naturally occurring marine compounds which in some instances result in significant consumer sickness following consumption of contaminated shellfish products. The toxins are found in shellfish grown in marine waters throughout the world, and many instances of human intoxication are reported annually.

Development of reference materials for paralytic shellfish poisoning toxins.

Journal of AOAC International, 2001
A project was undertaken to develop mussel reference materials that were certified for their mass fractions of saxitoxin and decarbamoyl-saxitoxin. Fifteen laboratories from various European countries participated. Three of these had major responsibility for substantial parts of the work and overall coordination of the project.

Comparison of paralytic toxins in aquaculture of purple clam in Taiwan

Toxicon, 1992
Food poisoning incidents due to ingesting the cultured purple clam Soletellina diphos occurred in western Taiwan in February 1991. Clam specimens, sediment and the dinoflagellate Alexandrium tamarensis were collected and assayed for lethality as paralytic shellfish poison (PSP).

Risk of human exposure to paralytic toxins of algal origin

Environmental Toxicology and Pharmacology, 2005
The most significant neurotoxins produced by harmful algal blooms (HABs) are paralytic shellfish toxins (PSTs) found in shellfish and freshwater. Human exposure to neurotoxins through the food consumption represents a severe hazard to human health and the exposure through contaminated water represents an added risk often difficult to recognize ...

Use of a channel biosensor for the assay of paralytic shellfish toxins

Toxicon, 1998
Gonyautoxin (GTX), saxitoxin (STX) and tetrodotoxin (TTX), also known as paralytic shellfish poisons (PSP), block Na+ channels, including those in the frog bladder membrane. A tissue biosensor has been developed, consisting of a Na+ electrode covered with a frog bladder membrane integrated within a flow cell. The direction of Na+ transfer, investigated

Occurrence of paralytic toxin in Taiwanese crab Atergatopsis germaini

Toxicon, 1996
Paralytic toxicity was detected by paralytic shellfish poison bioassay for all 17 specimens of the xanthid crab A. germaini collected from northern Taiwan in November 1993. The average toxicity of crab specimens was 3809 +/- 2591 mouse units (mean +/- S.D.).

Botulinum Toxin in the Treatment of Paralytic Strabismus

Neuro-Ophthalmology, 1996
In oculomotor palsies botulinum toxin A injections into extraocular muscles under electromyographic control represents a most efficient method, especially in the initial stages, to obviate disturbing and diplopia producing overaction resp. contracture of the homolateral antagonist of the paretic or paralyzed muscle or muscles.
