The delayed-type allergenicity of triforine (Saprol), 1,4-bis (2,2,2-trichloro-1-formamidoethyl) piperazine, was studied. In a mass examination of chrysanthemum growers among whom triforine was commonly used, the highest rate of positive patch test reaction was seen to triforine (17%) among the 7 pesticides and chrysanthemum extracts tested. A higher prevalence rate of work-related skin symptoms was seen in subjects with a positive patch test reaction to triforine (44%) than in those with negative reactions to all allergens tested (15%) (p < 0.05). 12 subjects (67%) with positive patch test reactions to triforine were also positive to dichlorvos (DDVP), with a high kappa coefficient (0.65). The grading of guinea pig maximization test to triforine was grade IV (66%), defined as "strong". Cross-sensitization between triforine and dichlorvos was also shown. The present results confirm that triforine is capable of including delayed-type allergy among chrysanthemum growers and of showing cross-reactivity with dichlorvos.

“…Two months after resolution of dermatitis, patch tests with M. scleroxylon ethanolic extracts (0.1%, 1%, and 5%) were performed. 4 Patch tests were occluded for 2 days with 6 The results of both tests were compared with those obtained with unstimulated and phytohaemagglutinin-stimulated cells. The T-lymphocyte activation test showed higher expression of CD69 with the highest concentration (1:10) of M. scleroxylon extract ( Figure S1a), whereas the Tlymphocyte proliferation test showed a higher response to the lowest concentration (1:1000) ( Figure S1b).…”
