Abstract

The attempted suicide by 2 women with a kyushin overdose is reported. Kyushin caused them to produce a significant elevation of a serum digoxin-like immunoreactive substance (2.35 and 1.84 ng/ml) and symptoms of nausea, vomiting and general malaise. Their blood biochemistry and electrolytes were normal. In one patient, an electrocardiogram revealed a second degree Wenckebach atrioventricular block and T-wave change. Toad venom, a kyushin ingredient, is possibly responsible for the development of these clinical features and electrocardiographic changes.
