1. Padrão de expressão de glicoconjugados nos folículos Bidderianos e ovarianos do sapo brasileiro Bufo ictericus, analisado por histoquímica de lectin
O órgão do Bidder e o ovário do sapo Bufo ictericus foram analisados por meio de microscopia de luz, utilizando a coloração pela hematoxilina-eosina (HE) e o método do ácido periódico de Schiff (PAS). A expressão e a distribuição de carboidratos foram verificadas por meio da histoquímica com lectinas, tendo sido utilizadas 8 lectinas com diferent

2. Composition and structure of the parasite community of Bufo ictericus (Spix, 1824) (Anura: Bufonidae) from Municipality of Miguel Pereira, State of Rio de Janeiro, Brazil / Composição e estrutura da comunidade parasitária de Bufo ictericus (Spix, 1824) (Anura: Bufonidae) do Município de Miguel Pereira, Estado do Rio de Janeiro, Brasil
Thirty-two specimes of Bufo ictericus (Spix, 1824), 22 males and 10 females, collected in the Municipality of Miguel Pereira, State of Rio de Janeiro, Brazil, from April 2003 to August 2003, were necropsied to study their metazoan parasites. Thirty-one (97%) specimens of B. ictericus were parasited by one or more metazoan species. Sixteen species of parasite

3. Comparative cytogenetic studies of Bufo ictericus, B. paracnemis (Amphibia, Anura) and an intermediate form in sympatry
Specimens of Bufo ictericus, Bufo paracnemis and a third type, considered an intermediate subgroup between these species, were cytogenetically studied by conventional Giemsa staining, C-banding and staining of the nucleolus organizer region (NOR). The nuclear DNA content and seroproteins were also analyzed to characterize these species, and verify the possib

4. Infestação de Amblyomma rotundatum (Koch) (Acari, Ixodidae) em sapos Bufo ictericus (Spix) (Amphibia, Bufonidae): novo registro de hospedeiro
Bufo ictericus Spix, 1824 toad population (N = 125) foraging in lighted areas in the Corupá Municipality, Santa Catarina State, was surveyed to evaluate the prevalence (percentage of infestation) and the mean infestation intensity of Amblyomma rotundatum Koch, 1844 (Acari, Ixodidae) ticks. The prevalence was of 19.2% and the mean infestation intensity was 7

5. Hydrins, hydroosmotic neurohypophysial peptides: osmoregulatory adaptation in amphibians through vasotocin precursor processing.
From neurointermediate pituitary glands of Xenopus laevis and Rana esculenta, previously unreported peptides termed hydrins, active on water permeability of frog urinary bladder and frog skin (Brunn or "water-balance" effect), have been isolated and sequenced. These peptides seem to be derived from the pro-vasotocin-neurophysin precursor. Hydrin 1, found in
