RESUMO
Rhodanese is one of the enzymes concerned in the detoxification of cyanide. Cassava intake and consequent cyanide toxicity are incriminated in the pathogenesis of goitre and calcific pancreatitis of tropics. So we studied the activity of rhodanese in these patients. 14 controls, 13 patients with pancreatitis and 12 with goitre were studied. The median (and range) of rhodanese in these groups were 82 (50-144), 110 (64-180) and 71 (22-160) units respectively. The serum rhodanese was significantly higher (P less than 0.05) in patients with pancreatitis when compared to the other groups. There was no significant difference between the serum rhodanese in patients with goitre and the controls. The presence of adequate amounts of rhodanese indicates that goitre and chronic pancreatitis are not produced by impaired cyanide detoxification.
