The leaves of
Baccharis dracunculifolia
are used to treat gastric disorders and febrile conditions, besides their use in
the treatment of wounds and inflammatory processes, among others. The objective
of this study was to evaluate the toxic effects of the alcoholic extract of
B. dracunculifolia
by means of morphological analyzes of the gills and gill rakers of
Prochilodus lineatus
fish. Of the 60 subjects, 32 were used in two experimental groups in duplicates:
Control group and treated group. After the treatment (21 days), 2 collections
were done at 14 and 21 days. The histological and histochemical changes were
evaluated by the Mean Value of Change (MVC), Histological Alteration Index (HAI)
and ImageJ®. HAI and MVC indicated normal functioning, with changes localized in
the organ. The results showed that the ingestion of the extract of
B. dracunculifolia
can affect the branchial epithelium and gill rakers, causing morphological
alterations and an increase of mucous substances, as well as the number of
lysosomes in the species studied.
Key words:
Asteraceae; mucus; lysosomes;
