Screening tests were carried out on the toxicity of freshwater puffers Tetraodon leiurus complex and Tetraodon suvatii collected from Udonthani province, north-eastern Thailand. Toxicity was highest in the liver and varied according to the location and season of fish catch. Fish which were reared in tap water for 3 months reduced the toxicity substantially. Partial purification was achieved by an ultrafiltration technique. Toxin components were consequently identified by high-performance liquid chromatography. It was found that toxins separated from the eggs, liver, skin and muscle of these puffers were composed of saxitoxin, neosaxitoxin and decarbamoylsaxitoxin.

UI MeSH Term Description Entries
D008387 Marine Toxins Toxic or poisonous substances elaborated by marine flora or fauna. They include also specific, characterized poisons or toxins for which there is no more specific heading, like those from poisonous FISHES. Marine Biotoxins,Phycotoxins
D009466 Neuromuscular Blocking Agents Drugs that interrupt transmission of nerve impulses at the skeletal neuromuscular junction. They can be of two types, competitive, stabilizing blockers (NEUROMUSCULAR NONDEPOLARIZING AGENTS) or noncompetitive, depolarizing agents (NEUROMUSCULAR DEPOLARIZING AGENTS). Both prevent acetylcholine from triggering the muscle contraction and they are used as anesthesia adjuvants, as relaxants during electroshock, in convulsive states, etc. Neuromuscular Blocker,Neuromuscular Blocking Agent,Neuromuscular Blockers,Agent, Neuromuscular Blocking,Agents, Neuromuscular Blocking,Blocker, Neuromuscular,Blockers, Neuromuscular,Blocking Agent, Neuromuscular,Blocking Agents, Neuromuscular

It includes virulence studies in animal fetuses in utero, mouse convulsion bioassay of insulin, quantitation of tumor-initiator systems in mouse skin, calculation of potentiating effects of a hormonal factor in an isolated strip of contracting stomach muscle, etc. Bioassay,Assay, Biological,Assays, Biological,Biologic Assay,Biologic Assays,Assay, Biologic,Assays, Biologic,Bioassays,Biological Assays
D012530 Saxitoxin A compound that contains a reduced purine ring system but is not biosynthetically related to the purine alkaloids. It is a poison found in certain edible mollusks at certain times; elaborated by GONYAULAX and consumed by mollusks, fishes, etc. without ill effects. It is neurotoxic and causes RESPIRATORY PARALYSIS and other effects in MAMMALS, known as paralytic SHELLFISH poisoning. Gonyaulax Toxin,Mitilotoxin,Saxitonin,Toxin, Gonyaulax
