Resumen
Acid phosphatase activity was investigated ultrastructurally in Malpighian tubules of Triatoma infestans. Enzyme activity was demonstrated in laminated 'concretions' (distal cells) and in typical lysosomes, as well as in basal plasmalemma infoldings and basement membranes (especially in distal cells). This activity was assumed to be related to the excretory functions carried out mostly by the distal cells. Heterochromatin-nucleolus functional relationships involving RNA transcription may promote the nuclear reaction verified in the proximal cells and in some distal cells. A lead phosphate precipitate appeared free in the cytoplasm encircling the nuclei and was assumed to be a contamination from the nuclear precipitates. 1998 372 33 42 Azeredo-Oliveira, M.T.V., (1982) Estudo Citoenzimológico Em Túbulos de Malpighi de Triatoma Infestans Klug, , MS dissertation, Instituto de Biologia, UNICAMP, Campinas (SP), Brazil Azeredo-Oliveira, M.T.V., Mello, M.L.S., Succinate dehydrogenase (SDH) activity in Malpighian tubules of Triatoma infestans Klug (Insecta, Heteroptera) (1985) Zool Jb.
