Acute voluntary intoxication by ricin.

1 A 21-year-old student ingested thirty ricin seeds in a suicidal attempt, some of which were masticated. Three hours later he developed severe diarrhoea with vomiting and abdominal cramps, followed by extracellular dehydration and circulatory collapse. 2 Biological changes included haemoconcentration. He recovered following symptomatic treatment by infusion of saline and glucose solutions. 3 Ricin was quantified by a radioimmunologic method using Iodine 125, and showed that only a small part of the ricin contained in the seeds was absorbed.
