SDH activity in heavy metal-treated malpighian tubules of Triatoma infestans Klug (Hemiptera, Reduviidae)

A variable effect of Cu2+ and Hg2+ ions on the intensity and localization of the SDH activity was cytochemically detected in the Malpighian tubule cells of the blood-sucking insect, Triatoma infestans. Unaffected and decreased enzyme activities as well as a change in the spatial distribution of mito...

More Information
Summary:A variable effect of Cu2+ and Hg2+ ions on the intensity and localization of the SDH activity was cytochemically detected in the Malpighian tubule cells of the blood-sucking insect, Triatoma infestans. Unaffected and decreased enzyme activities as well as a change in the spatial distribution of mitochondria were detected on the basis of the cytochemical localization of the enzyme. It is assumed that these metal ions could affect not only the mitochondrial performance but also other cell functions which require a specific mitochondrial distribution.
