Tannins occurring in the toxic Brazilian plant Thiloa glaucocarpa.

Four tannins were isolated from dried leaves of Thiloa glaucocarpa, which is one of the plants causing poisoning of cattle in Brazil. These four tannins were determined from spectrometric and chemical evidence to be the ellagic C-glucosyl tannins vescalagin, castalagin, stachyurin and casuarinin. The main components, vescalagin and castalagin, are also known as constituents of oak (Quercus spp.), the toxicity of which for cattle is supposed to be due to tannins. Suggestions concerning the resemblance of the symptoms of poisoning by Thiloa glaucocarpa and by oak are supported by the presence of the constituents in both plants.

Isolation and characterization of myotoxic phospholipases A2 from crotalid venoms.

Phospholipases A2 producing myonecrosis when injected i.m. into mice were isolated from venoms of Trimeresurus flavoviridis, Agkistrodon bilineatus, A. c. contortrix, A. c. mokeson, A. p. piscivorus and Bothrops asper by gels filtration on Sephadex G-75 followed by ion-exchange chromatography on CM-cellulose. They are basic enzymes with molecular weights between 14,000 and 15,000 containing 120-129 amino acid residues and exhibit relatively low enzymatic activity when tested on egg yolk suspension. Local myonecrosis is induced even at doses of 1.25 micrograms per mouse.

[Poisoning after ingestion of mussels (mytilus edulis) (author's transl)].

Symptoms of poisoning occurred in 19 persons in the Rhein-Main region in October 1976, after they had eaten mussels (Mytilus edulis) imported from Vigo, Spain. Mild oral paraesthesias, tingling in the fingertips and feet were followed by generalised numbness and dizziness. All symptoms disappeared within 48 hours. They had been caused by saxitoxin which is produced by a dinoflagellate and accumulated in the mussels, as confirmed by testing confiscated samples of mussels. Toxin concentration ranged from 6000 to 20 000 MU (mice units) per 100 g mussel meat.
