Cortes histológicos de 120 mexilhões Perna perna (Linnaeus, 1758), coletados na Lagoa de Itaipu, Niterói, RJ, por um período de 12 meses, foram examinados quanto a presença de parasitas e lesões. Noventa exemplares apresentaram cinco diferentes processos patológicos: bucefalose, presença de protozoários Nematopsis sp., inclusões basofílicas não específicas, encapsulamentos parasitários e cistos epiteliais branquiais. Cinquenta animais mostravam duas ou mais patologias concomitantes.

Objective: to build a specialized terminology for the clinical nursing practice for people with COVID-19, based on the Seven Axis Model of the International Classification for Nursing Practice. Methods: a descriptive and documentary study, carried out in April 2020. The terms were extracted from official documents of the Ministry of Health. The data were treated through terminological analysis, that is, the terms were organized through a classification system, which, in this research, was represented by the Seven Axis Model, version 2019. Also in the delimitation of the thematic field of the terminological analysis, the method of cross-mapping was chosen so that the terms resulting from the normalization process, derived from the literature, were cross-referenced with the terms of the International Classification for Nursing Practice in its seven axes. Results: after the normalization process, 472 useful terms were found. These were submitted to cross-mapping, totaling 263 constant terms and 211 non-constant terms. Conclusion: the study allowed identifying terms in the literature, which can be used by nurses in the care of people affected by COVID-19 and will support the stages following the construction of a terminological subset for information and communication to the Nursing practice.

ABSTRACT. Gametogenic and histochemical aspects of edible bivalve Iplzigellia brasiliana (Lamarck) (Bivalvia, Donacidae) from the Itaipu lagoon, Nitel'ói, Rio de Janeiro, Brazil. Gametogenic and histochemical aspects of an edible bivalve, Iphigenia brasiliana (Lamarck, 1818) from Itaipu Lagoon, Niterói, State of Rio de Janeiro, were studied. Between May 1998 and October 1999 a total of 120 c1ams were picked up . Samples of 10 animais were collected once a month. Specimens were fixed in Bouin's tixative for 4 hours or less and transferred to 10% fonnalin for 24 hours. The shell lenght has been measured with the valves lightly opened to permit the penetration of f1xative solution deeply in the tissues. Transverse seetions including digestive diverticula, mantle, gill s, gonad and foot were obtained from the total body. Aner tixative treatment, tissues see tion s were embedded in paraffin, eut routinely at 5 flm and stained with Harris's hematoxylin and eosin. Microscopic analysis was earried out at low and high dry magnifications, as well as under oi l immersion . Advaneed ova stages were measured. Speeial stai ning techniques have been app li ed as a tentative tool for searehing glyeogen, mueous eells, eollagenie and retieulin fibers, RNA and protozoan organisms. The anima is eolleeted showed variation in lenght Irom 7.20 em to 4.10 em and in height from 4.60 em to 3.10 em. The sex rati o (M:F) was 40:69. The average ova diameter of I. brasiliana was 34.70 /lm with a standard deviation of5.19 /lm. Nothing eould be observed in I. brasiliana, eoncerning to lesions and parasites at histopathologieal analysis. KEY WORDS . Gametogenic cycle, histology, special-staining methods, lphigenia brasiliana, Itaipu Lagoon, BrazilIphigenia brasiliana (Lamarck, 1818) é encontada enterrada aproximadamente a até 15 cm de profundidade, no fundo areno-argiloso ou lodoso de baías e enseadas. Seu nome vulgar é "tarioba", segundo BOFFI (1979). No Brasil, atinge os Estados do Paraná e de Santa Catarina (GOFFERJÉ 1950) e São Paulo e Rio de Janeiro (LANGE DE MORRETES 1949). Na Lagoa de Itaipu é denominada de "taioba" e é consumida não só pela população local, como também por alguns cidadãos da colônia nipônica para o preparo de sopas e outros pratos orientais. Na espécie estudada, as gônadas ocupam o espaço entre as regiões do canal alimentar na massa visceral, não se estendendo para o manto . As aberturas genitais ficam na s uperfície posterior dorsal da massa visceral, abaixo do nefrídio e abrem-se

ResumoForam realizadas cento e cinqüenta necropsias em cinco espécies de peixes teleósteos de origem marinha comercializados no Mercado São Pedro, Município de Niterói, Rio de Janeiro. Utilizaram-se trinta exemplares para cada espécie de Pagrus pagrus, Pomatomus saltator, Priacanthus arenatus, Cynoscion sp. e Caranx latus, com o objetivo de verificar a prevalência e intensidade média de infecção de parasitas da ordem Trypanorhyncha. Com o auxílio de estereomicroscópio, os plerocercos foram liberados por meio de estiletes, colocados em placas de Petri com água e levados ao refrigerador por 24 horas. Após este tempo, foram processados segundo a técnica descrita por Amato et al. (1990) e identificados segundo Beveridge e Campbell (1994). As espécies Pagrus pagrus e Priacanthus arenatus estavam negativas para parasitas da ordem Trypanorhyncha. No gênero Cynoscion sp. foram observadas prevalência de 16,67% e média de intensidade de infecção de 0,17 parasitas por hospedeiro para Pterobotrium crassicolle. Em Caranx latus e Pomatomus saltator verificaram-se prevalência e intensidade média de infecção para Callitetrarhynchus gracilis de 33,33% e 0,57 parasitas por hospedeiro e, de 36,67% e 0,60 parasitos por hospedeiro, respectivamente, sendo encontrado em P. saltator para C. speciosus prevalência de 3,33% e intensidade média de infecção de 0,03 parasitas por peixe. Os inspetores de pescado devem estar atentos à presença destes parasitas em peixes marinhos, pelo aspecto repugnante que transferem ao produto.Palavras-chave:Trypanorhyncha, parasitas, peixes. AbstractA hundred and fifty necropsies have been done in five species in teleostean fishes in marine fishes commercialized in Niterói, Rio de Janeiro State. Were utilized thirty fishes for each species of Pagrus pagrus, Pomatomus saltator, Priacanthus arenatus, Cynoscion sp. and Caranx latus, with the objective of verifying the prevalence and the medium intensity infection of parasites from Trypanorhyncha order. The plerocercus were set free thru stiletto and set in Petri plate with water being kept under refrigeration per 24 hours. After this period, were processed following Amato's et al (1990) technics and identified following Beveridge and Campbell (1994). In Pagrus pagrus and Priacanthus arenatus were negatives for parasites from Trypanorhyncha order. In Cynoscion sp were found prevalence of 16,67% and medium infection intensity of 0,17 parasites per host for Pterobotrium crassicolle while in Caranx latus and Pomatomus saltator were found prevalence and medium infection intensity for Callitetrarhynchus gracilis of 33,33% and 0,57 parasites per host, as well, 36,67% and 0,60 parasites per host, respectively, being found in P. saltator for C. speciosus prevalence of 3,33% and medium infection intensity of 0,03 parasites per host. Fish sanitary inspectors must be aware of the presence of parasites from Trypanorhyncha order in marine fishes by the repugnant aspect that they transfer to the products.Keywords: Trypanorhyncha, parasites, fishes.
