Els Senadors republicans catalans durant la monarquía d’Alfons XIII (1903-1923)

Si bé durant el primer quart del segle XX la presència de republicans en el Senat fou sempre escassa, l'autor ha comptabilitzat, entre 1903 i 1923, 31 actes de republicans en el conjunt d'Espanya, 16 de les quals corresponen a senadors catalans. Durant aquest perí­ode, Catalunya fou el baluard més potent del republicanisme a Espanya.

Estudos citológicos e citoquímicos em Stenophoridae crawley, 1903 (Eugregarinidae, Protozoa): I - microscopia óptica e citoquímica do núcleo

Neste trabalho os autores apresentam uma revisão da morfologia das gregarinas do gênero Stenophora Labbé, 1899, baseada principalmente em S. juli (Frantzius, 1848) Labbé, 1899. Caracterizam citoquìmicamente os elementos da estrutura nuclear, ficando evidenciado que o corpúsculo nuclear referido por muitos como um cariossomo apresenta reações positivas para o RNA, sendo portanto um nucléolo. O suco nuclear apresenta reações para o DNA pouco intensas, devido as granulações de cromatina se apresentarem muito finas. Fazem referências também à estrutura do nucléolo, que varia com as técnicas empregadas e salientam a necessidade de comparação dêstes resultados com aquêles obtidos com o auxílio da microscopia eletrônica e que são tratados no segundo trabalho desta série.

Estudos citológicos e citoquímicos em Stenophoridae Crawley, 1903 (Eugregarinidae, Protozoa) II - ultra-estrutura

1 - Indivíduos de Stenophora juli (Frantzius, 1848) Labbé, 1899, parasitos de um Diplopoda, Rhinochricus padbergi Schubart. 1930 foram examinados em microscópia óptica e eletrônica. 2 - Os resultados do estudo citoquímico confirmam os dados obtidos por outros autores em outras espécies de gregarinas. 3 - Quanto à estrutura fina da morfologia celular foi examinada detalhadamente a película a qual apresenta cristas longitudinais de forma e estrutura complexas. 4 - No sulcos da película, entre as cristas, foram encontrados poros na membrana, por onde é realizada a secreção de muco. 5 - Aderente à película, pròpriamente dita foi encontrada, no deutomerito, uma camada homogênea de natureza desconhecida, abaixo da qual encontra-se o mionema. 6 - O septo que separa o proto do deutomerito é constituído por espêssa camada de mionemas incluindo numerosas mitocôndrias. 7 - O endoplasma é extremamente rico em granulações de paraglicogênio, aparecendo em menor quantidade os lipídeos. Observamos também mitocôndrias, retículo endoplasmático e o complexo de Golgi.

Physa Marmorata Guilding, 1828 (Pulmonata: Physidae)

A description of Physa marmorata Guilding, 1828, based on material collected at its type-locality, the Caribbean island of Saint Vincent, is presented. The shell is thin, horn-colored, surface very glossy, diaphanous. Spire acute, elevated; protoconch distinct, rounded-conical, reddish-brown; five not shouldered, broadly convex whorls with subobsolete spiral lines and thin growth lines. Aperture elongated, 1.4-2.0 times as long as the remaining shell length, narrow obovate-lunate; upper half acute-angled,lower half oval,narrowly rounded at the base, outer lip sharp, inner lip completely closing the umbilical region; a very distinct callus on the parietal wall; columellar lip with a low ridge gradually merging into the callus. ratios: shell width/shell length = 0.44 - 0.52 (mean 0.47); spire length /shell lenght = 0.33-0.41 (mean 0.39); aperture length/shell lenght = 0.59-0.67 (mean 0.62). Oral lappets laterally mucronate, foot spatulate with deeply pigmented acuminate tail. Mantle reflection with 6-10 short triangular dentations covering nearly half the right surface of the body whorl, and 4-6 covering a part of the ventral wall. Body surface with tiny dots of greenish-yellow pigment besides melanin. Renal tube tightly folded in toa zigzag course. Ovotestis diverticula acinous, laterally pressed against each other around a collecting canal. Ovispermiduct with well-developed seminal vesicle. oviduct highly convoluted, merging into a less convoluted nidamental gland which narrows to a funnel-shaped uterus and a short vagina. Spermathecal body oblong, more or less constricted in the middle and somewhat curved; spermathecal duct uniformly narrow, a little longer than be body. About 20 prostatic diverticula, simple, bifurcate or divided into a few short branches, distalmost ones assembled into a cluster. Penis long, nearly uniformly narrow; penial canal with lateral opening about the junction of its middle and lower thirds. Penial sheath with a bulbous terminal expasion the tip of which isinserted into the caudal end of the prepuce. Prepuce shouldered, much wider than the narrow portion of the penial sheath. Penial sheath/prepuce ratio about 2.08 (1.45-2.75). The main extrinsic muscles of the penial complex are a retractor, with a branch attached to the bulb, and another to the caudal end of the penial sheath; and a protractor, with a branch attached to the shoulder of the prepuce and adjoining area of the penial sheath, and another to the caudal end of the penial sheath. Egg capsule C-shaped, with 10-30 elliptical eggs (snails 10mm long) measuring about 1.10 mm (0.90-1.32) through the long axis and surrounded by an inner and an outer lamellate membranes. Jaw a simple obtusely V-shaped plate. radula will be described separately.

Susceptibility of laboratory-reared female Lutzomyia longipalpis (Lutz & Neiva, 1912) to infection by different species and strains of Leishmania Ross, 1903

A study was undertaken to compare the susceptibility of laboratory-reared female Lutzomyia longipalpis to infection by different species or strains of New World Leishmania. The sand flies proved to be highly susceptible to infection by a strain of Le. guyanensis, with flagellates developing in all (18/18) of the specimens examined. A lower infection rate of 37 per cents (10/27) was recorded in flies exposed to infection by a strain of Le. amazonensis. Flagellates developed in 13 per cents (6/46) of the sand flies that glood fed on dogs in the earlly stage of experimental infection with an old laboratory strain of Le. chagasi. In contrast, promastigotes did not develop in sand flies that blood fed on dogs with naturally acquired Le. chagasi. The naturally infected dogas were in an advanced stage of disease. Flagellates developed in 9// (3/32) of the sand flies that blood fed on lesions of hamsters infected with a strain of Le. braziliensis and in 9 per cents (3/34) of those that fed on hamsters with lesions due to a parasite fo the mexicana complex (strain MHOM/BR/73/BH121). Sand flies did not develop flagellate infections after blood feeding on hamsters bearing lesions induced by strain MHOM/BR/71/BR49. Factors influencing the susceptibility of Lu. longipalpis to infection by New World species of Leishmania are discussed.
