Medicinal plants used by "Passo da Ilha" rural community in the city of Pato Branco, southern Brazil

O objetivo deste trabalho foi resgatar e documentar o conhecimento popular referente às plantas medicinais utilizadas na comunidade rural do Passo da Ilha, em Pato Branco-PR (26° 11' S, 52°36' W e 760 m de altitude). Optou-se por utilizar o modelo de entrevista estruturada com 16 informantes, os quais possuíam o conhecimento sobre o uso das plantas medicinais em suas famílias. O período da realização das entrevistas foi de outubro a dezembro de 2000. As plantas foram coletadas no campo, identificadas e vouchers foram depositados no Herbário Irina Delanova de Gemtchjnicov (BOTU) da Universidade Estadual Paulista, em Botucatu-SP. Foram identificadas 47 famílias botânicas e 114 espécies de plantas medicinais. Estas plantas foram indicadas para mais de 30 usos medicinais diferentes. A comunidade é composta na maioria por descendentes de europeus, justificando a presença de muitas plantas exóticas. O domínio do uso das plantas é feminino, porém o conhecimento é menor nas gerações mais novas, denotando um processo de erosão cultural.

This study is the first assessment of mollusk fossil assemblages relative to the compositional fidelity of modern mollusk living and death assemblages. It also shows that the sedimentary record can provide information on the original, non-human-impacted, freshwater malacofauna biodiversity, based on Late Pleistocene shells. The fossil mollusk assemblage from the Touro Passo Formation (Pleistocene-Holocene) was compared to living and death assemblages of the Touro Passo River, southern Brazil, revealing little resemblance between fossil and live-dead species composition. Although the living and death assemblages agree closely in richness, species composition, and species relative abundances (both proportional and rank), the fossil assemblage differs significantly from both modern assemblages in most of these measures. The fossil assemblage is dominated by the native endemic corbiculid bivalve Cyanocyclas limosa and the gastropod Heleobia aff. bertoniana. These are absent in the living assemblages, and both living and death assemblages are dominated by the alien Asiatic corbiculid C. fluminea, which is absent in the fossil assemblage. The fossil assemblage also contains, overall, a higher proportional abundance of relatively thick-shelled species, suggesting a genuine bias against the thinner- and smaller-shelled species. Our results suggest that contemporary environmental changes, such as the introduction of some alien freshwater mollusk species, together with post-burial taphonomic processes, are the main factors leading to the poor fidelity of the fossil assemblage studied. Hence, the taxonomic composition of the Late Pleistocene mollusks from the Touro Passo Formation probably would show greater similarity to present-day assemblages wherever the mollusk biodiversity is not disturbed by human activities.

We examined the EEG of 88 patients with chronic renal failure (80 adults and 8 children) submitted to different types of treatment such as hemodialysis, peritoneal dialisys, renal transplantation, and ambulatory follow-up. The main alteration observed was diffuse disorganization of background activity. The following features were detected in decreasing order of frequency: low-voltage EEG, triphasic waves, abnormal waking reactions, and paradoxal alpha rhythm. The children showed abnormal alpha rhythm. The alterations induced by intermittent photic stimulation in our patients were minimal, and this was the main difference in relation to data reported by other authors in EEG studies on patients with chronic uremia.

Three sympatric species of Gymnotus from the Fundo stream, a small tributary of the Sapucai river, Minas Gerais State, Brazil, were studied in relation to their karyology. Gymnotus sylvius presented 2n=40 chromosomes (36 m/sm+4 st/a), Gymnotus sp. presented 2n=50 (26 m/sm+ 24 st/a) and Gymnotus paraguensis had 2n=54 (50 m/sm+4 st/a). C-banding demonstrated positively stained heterochromatic blocks in the centromeric position of few chromosomes on G. sylvius and in the centromeric region of all chromosomes on G. paraguensis samples. The nucleolus organizer region (NOR) was located on the short arm of one st chromosome pair in G. sylvius and Gymnotus sp., and in the interstitial position on the short arm of the pair number one and below the centromere on a third chromosome on G. paraguensis. The cytogenetic data obtained indicate that Gymnotus sp. represent a new Gymnotus specie with a karyotypic constitution never observed on others species from this genus. Some aspects related to the chromosome diversification of these Gymnotus are discussed. © 2007 The Japan Mendel Society.
