Notas sôbre a evolução do virus vacínico em animais silvestres da fauna brasileira

A note on the evolution of cow-pox virus in wild animals of Brazilian fauna. We have tried the sensibility of wild animals of Brazilian fauna to the cow-pox virus. The following specimens were submitted to experiences: Procyon cancrivorus, Hydrochoerus capybara, Cavea aperea, Coendu villosus, Didelphis aurita, Bradypus tridactylus, Euphractus sexcintus, Tamandua tetradactylus, Nasua narica, Dasyprocta aguti and Testudo tabulata. In all these animals, - excepting Bradypus tridactylus - we have obtained an infection with incubation (five days), aspect and duration similar to cow-pox of the laboratorial animals (calf and rabbit). In the Bradypus tridactylus howewer, the incubation was very long. Only after 30 days of inoculation we verified the infection with the formation of vesiculae and postulae.

Trematódeos monogenéticos (Polistomatas) da costa brasileira I. sobre Loimos scitulus sp. n. (Loimoidae) e Tagia ecuadori (Meserve, 1938) Sproston, 1946 (Diclidophoridae)

Em continuação aos estudos dos trematódeos monogenéticos da Coleção Helmintológica do Instituto Oswaldo Cruz, descrevemos no presente trabalho uma espécie do gênero Loimos MacCallum, 1917, Loimolinae Price, 1936, loimoidae Bychowsky, 1957 que consideramos nova para a ciência, e assinalamos nova ocorrência de Tagia ecuadori (Meserve, 1938) Sproston, 1946, Tagiinae Yamaguti, 1963, Diclidophoridae Najibina & Obonikova, 1971, no Atlântico Sul. Loimos scitulus sp. n. diferencia-se das outras espécies do gênero pelos seguintes caracteres: forma e estrututra do proaptor, oótipo grande, número de testículos, posição do poro genital, filamento do ovo e forma de opistaptor. Dentre as diferenças dadas Loimos scitulus sp. n. aproxima-se de L. salpinggoides pela estrutura do proaptor, de L. secundus pela posição do poro genital; de L. winteri pelo opistaptor. Quanto aos exemplares de Tagia ecuadori por nós estudados, apesar de ter sido evidenciada uma vagina, identificamos a esta espécie, por apresentar estruturas e medidas que se enquadram nas variações dadas pelos estudiosos do grupo.

O autor descreve uma nova espécie de poliplacóforo (Acanthochitona terezae) para o litoral brasileiro, apresenta dados sobre sua morfologia e discute aspectos biogeográficos.

La Olimpiada Popular de 1936: deporte y política

Las complejas relaciones entre política y deporte y, más concretamente aún, entre deporte y pulsión nacionalista, son exploradas por el autor a la luz de la Olimpíada Popular de 1936, organizada –y finalmente no celebrada– en la Barcelona inmediatamente anterior al golpe de Estado del 18 de julio como réplica y alternativa a los Juegos Olímpicos que aquel verano se celebraron en Berlín, entonces capital del incipiente Tercer Reich.

Remeis casolans per a bèsties i humans: medicina i veterinària popular a la catalunya central

Treball de recerca realitzat per un alumne d’ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l’any 2008. Consisteix en un diccionari informàtic que recull plantes i productes, cadascun amb les seves propietats medicinals i altres usos que se’ls atribueixen popularment i la forma de preparar remeis i aplicar-los per a cada malaltia o afecció. La informació s’ha extret de les entrevistes fetes a informants d’entre 60 i 90 anys del Bages, Berguedà i Solsonès, i es complementa amb un herbari i una mostra de preparacions dels remeis.

Que bèstia!: anàlisi del bestiari popular català

Treball de recerca realitzat per una alumna d’ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l’any 2008. Els objectius d’aquest treball són d’una banda determinar i analitzar les característiques generals de l’actual bestiari festiu popular de Catalunya, diagnosi global mai realitzada fins ara. De l’altra s’ha intentat establir una relació entre el bestiari popular català actual i els seus orígens més remots, prenent l’exemple d’una de les bèsties més curioses del nostre bestiari: la víbria.

Padrões distributivos e zoogeografia dos moluscos da plataforma continental brasileira: Parte III. Comissão Oceanográfica Espiríto Santo I

One hundred senventy-five species of marine mollusks have been identified in the Expedition Espírito Santo I. Standing out the species Margarites olivaceus (Brown, 1827); Cyclostremiscus caraboboensis Weishord, 1962; Balcis gibba Folin, 1867; Triphora compsa (Dall, 1927); Henrya af. goldmani Bartsh, 1947 and Limaea subovata Jeffreys, 1876 as they have not been previously assigned to Brazil. The analysis of the geographical distribution patterns points out the dominance of the species with thermophiles affinities. This situation evidences the importance of the Brazilian Current in the maintanance of the biogeographical structure of the studied region. However, it is the analysis of the cryophiles species that shows the Cabo Frio region as an ecological filter quite more permeable to the species with thermophile affinities than to the cryophiles ones. The existence of this barrier and the endemism rate (4.27%) characterize the region that extends from the south of Cabo Frio as a transition between the two patterns cited above. Therefore they do not corroborate in malacological parameters the proposition made by Palacio (1982) for the individualization of the Paulista Province.

A cronologia da descoberta dos transmissores da malária na Amazônia brasileira

In the Amazon Region of Brazil, during the first three decades of this century, anophelines of the subgenus Nyssorhynchus not precisely identified to species were regarded as the probable malaria vectors. In 1931 and 1933 Anopheles darlingi, and in 1942-1946 An. aquasalis were confirmed as carriers, the former in the interior, the latter along the coast, because of their habits and salivary gland infection. An. albitarsis and An. braziliensis seemed to be occasional, secondary vectors. Forty years later, through immunological tests, other species are being pointed as naturally infected: An. triannulatus, An. nuneztovari, An. oswaldoi, An. strodei, An. galvaoi and An. peryassui. The importance of all incriminated species except An. darlingi (the main vector wherever present) and An. aquasalis has yet to be measured.

Megalobulimus lopesi sp. n., uma nova espécie de Pulmonata terrestre da Mata Atlântica brasileira (Mollusca, Gastropoda, Megalobulimidae)

Megalobulimus lopesi, a new species of megalobulimidae, is described with basis on conchyological and anatomical characters. It is very close to M. grandis (Martens, 1885), the largest species of land gastropds of Brazil, from Sao Sebastiao Island (23º49'S 45º20'W).

Toxicological and toxicogenetic effects of plants used in popular medicine and in cattle food

Toxicological and toxicogenetic effects of aqueous (tea) and hexanica fruit extract of Indigofera suffruticosa Mill, and hydroalcoholic root extract od Solanum agrarium Stendt. Were evaluated in Balb C male mice intraperitoneally exposed. A hepatotoxic effect was observed just for animals treated with aqueous fruit extract of I. suffruticosa. In relation to the toxicogenetic effect, just the group trreated with 12.5% of toxic dose of aqueous fruit extract of I. suffruticosa showed a statistically significant increase in the frequency of cells with chromosome aberrations (cytogenetic effect), although a slight increase was also observed for the highest dose (25% of LF50_ of hydroalcoholic root extract of S. agrarium. The results obtanied show that before S. agrarium is used as medicine and before the wide use of I. suffruticosa in cattle food, careful evaluation must be done.

La literatura popular del nord del Marroc

Treball de recerca realitzat per una alumna d'ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit cientí¬fic del Jovent l'any 2009. L’objectiu d’aquest treball és fer un recull de literatura de transmissió oral i reunir d’aquesta manera les històries, els contes, les llegendes. etc. que els avis de l’autora li contaven. Un dels objectius era que servís alhora de mitjà de coneixement per a tots els nens i nenes que, tenint un origen marroquí o berber, han nascut a Catalunya, per la qual cosa no han tingut accés a aquest tipus de literatura. Ja que, per una banda han estat sempre escolaritzats en català, i per l altra la font de coneixement que suposen els avis s ha quedat al Marroc. Aquests nens tenen poc coneixement sobre la seva cultura d’origen i més si aquesta gaudeix de poc valor.
