Influence of fluoride on activity of carboxylesterase and esterase in hemolymph of Bombyx mori

Influence of fluoride on activity of carboxylesterase and esterase in hemolymph of Bombyx mori

We explored the metabolic mechanism of silkworm (Bombyx mori) to NaF by using the fluoride-tolerant silkworm variety named T6 and the fluoride-sensitive variety named 734 as materials. We fed the silkworm larvae from the first day of fifth instar with mulberry leaves soaked in 50, 100, 200 and 400 m...

description We explored the metabolic mechanism of silkworm (Bombyx mori) to NaF by using the fluoride-tolerant silkworm variety named T6 and the fluoride-sensitive variety named 734 as materials. We fed the silkworm larvae from the first day of fifth instar with mulberry leaves soaked in 50, 100, 200 and 400 mg/kg NaF solutions respectively. Then we examined the activities of CarE and esterase in hemolymph. Results showed that the activity of CarE was 73% to 88% in 734 strain and 72% to 81% in T6 strain compared with control groups, respectively. The CarE activity of two low concentration NaF-treated 734 groups showed extremely significant differences(P
