Análise do conteúdo estomacal de possíveis predadores de Simuliidae (Diptera: Nematocera), em dois igarapés de terra firme na Amazônia Central, Brasil

O conteúdo estomacal de insetos (Plecoptera e Odonata), crustáceos e peixes foi analisado por meio de dissecção para se verificar a predação sobre imaturos de simulídeos e identificação dos outros itens alimentares. O trabalho foi realizado em dois igarapés da Reserva Florestal Adolpho Ducke (Sabiá-I), Manaus - AM, pertencente ao Instituto Nacional de Pesquisas da Amazônia (INPA), com espécimes coletados mensalmente no período de abril de 1992 a maio de 1993 e nos meses de novembro de 1993 e junho de 1994. As coletas foram realizadas por meio de cestas-armadilhas (contendo folhas de jambeiro, Eugenia malaccensis L., Myrtaceae) e rapiché. Constatou-se a predação de imaturos de Simuliidae por um exemplar de peixe (Microcharacidium gnomus, Characidae), Plecoptera (Perlidae) e Odonata (Gomphidae, Agrionidae, Libellulidae, Dicteriadidae e Coenagrionidae). Outros itens alimentares observados nos organismos analisados foram Diptera (Chironomidae), Trichoptera (Hydropsychidae, Hydroptilidae), Coleoptera (Elmidae), Hymenoptera (Formicidae), Ephemeroptera (Baetidae, Leptophlebidae), outros insetos, ovos de insetos, Hydracarina, Crustacea, Nematoda, detritos e restos vegetais

Morphometric Comparison of Simulium perflavum Larvae (Diptera: Simuliidae) in Relation to Season and Gender in Central Amazônia, Brazil

Number of larval instars, age structure and environmental effects on these parameters represent basic information in the study of insect population biology. When species have economic importance, this information is essential in order to choose the best period to apply different control methods and to determine the stages of the life cycle of the insect that are most susceptible to each treatment. The family Simuliidae has many species of medical/veterinary importance in the world, and some studies in the temperate region have suggested that the number of larval instars and the larval size can vary according to the season, gender and some environmental factors, such as temperature and diet. This study, with the zoophilic species Simulium perflavum Roubaud, is the first in the Neotropics observing some of these factors and will serve as a template for other species of medical importance in the region. S. perflavum larvae were collected in five streams in Central Amazônia (Manaus and Presidente Figueiredo counties, State of Amazonas), in Sept./Oct. 1996 (dry season) and Feb./Mar. 1997 (rainy season). These larvae were measured (lateral length of head capsule and width of cephalic apodema) to determine the number of larval instars (n=3985), to compare the larval size between seasons and genders (last and penultimate larval instars, n=200). Seven larval instars were determined for this species using frequency distributions, t-tests and Crosby's growth rule. Significant differences were not detected (t-test, p>0.05) in larval size between seasons and genders. Our results differ from some found in temperate regions suggesting that in the Neotropical region the larval size in different seasons and different genders remains constant, although some environmental parameters, such as diet, change depending on the season

МОДЕЛИРОВАНИЕ ВЛИЯНИЯ СКОРОСТИ ВЗАИМОДЕЙСТВУЮЩИХ ЧАСТИЦ И ПУЗыРЬКОВ НА ВОЗМОЖНОСТЬ ОБРАЗОВАНИЯ ФЛОТАЦИОННОГО КОМПЛЕКСА

Проблема и ее связь с научными и практическими задачами. Уголь пред-ставляет собой ценное сырье для дальнейшей химической переработки с целью получения необходимых для промышленности продуктов, а также является од-ним из главных источников получения тепловой энергии. Современные уг-леобогатительные предприятия постоянно сталкиваются с проблемой обогаще-ния шламов

Notes on artificial substrates for black fly (diptera: simuliidae) larvae and microsporidian infection in Central Amazonia, Brazil.

Comparou-se três tipos de substratos (filamento plástico branco; ladrilho, blocos de ardósia cinza; e fita plástica, cor amarela) na captura de larvas de simulídeo em 5 períodos de exposição (1, 5, 7, 10 e 14 dias). O estudo foi realizado a 51 km a SE de Manaus, AM, onde foram coletadas 3 espécies: Simulium quadrifidum Lutz (81%), Simulium sp. (17,3%) e Simulium perflavum Roubaud (1,7%). Através da análise de variância dos parâmetros estudados verificou-se diferenças significativas entre os substratos utilizados (P < 0,001), mas não entre os períodos de colonização. A fita plástica foi o substrato mais eficiente para capturar imaturos de simulideos (P < 0,05), não havendo diferença significativa entre os substratos ladrilho e filamento plástico. Durante o período de estudo foi observado infecção por microsporídio (Amblyospora bracteata (Strickland)) apenas em S. quadrifidum

A influência do uso de prótese sobre a evolução da cardiopatia isquêmica em pacientes amputados transfemurais

The objective of the work was to bring up, from files at AACD, information that perrnits us to study the evolution of the ischemic cardiopathy on patients engaged to the postamputation rehabilitation programo For that, the 116 patients on the matter, were ranked between prosthetic and non prosthetic and with arm ergometric (AE) and inicial positive AE. Among the 116 patients on the matter, only 40 (26 fitted and 14 non fitted with prosthesis) were submitted to a complete cardiological follow-up (inicial and retest AE); the other 76 patients were subrnitted to only the inicial AE. Out of 40 patients with a complete cardiological follow-up, 15 (32,5%) had inicial positive AE for ischernic cardiopathy and 25 (65,5%) out of 40 patients has negative AE, showing a high incidence of the disease among the amputee. The follow-up of the retest results for the 25 patients with inicial nega tive AE permitted the study for instalation of ischemic cardiopathy. In this group (25 patients), 12 patients (48%) presented positive results for the retest. However, an incidence of positive results for the retest is different (p&lt;0.05) among prosthetic patients (35%) and non prosthetic (100%). Talking into consideration the lirnits of this study, it's conc1uded that it exists a great incidence of ischemic cardiopathy on amputated patients and that, probably, the use of prosthesis can reduce the incidence of ischemic cardiopathy on unilateral and bilateral amputated patients as far as the thigh is concerned.O objetivo desse trabalho foi levantar, nos arquivos da AACD, informações que permitissem o estudo da evolução da cardiopatia isquêmica em pacientes engajados no programa de reabilitação pós-amputação. Para isso, os 116 pacientes estudados foram categorizados em protetizados e não-protetizados e com teste ergométrico de membros superiores (TEMS) inicial negativo TEMS inicial positivo. Dentre os 116 pacientes estudados somente 40 (26 protetizados e 14 não-protetizados) realizaram o acompanhamento cardiológico completo (TEMS inicial e reteste); os outros 76 pacientes realizaram somente o TEMS inicial. Dos 40 pacientes com acompanhamento cardiológico completo, 15 (32,5%) tinham TEMS inicial positivo para cardiopatia isquêmica e 25 (67,5%) tinham TEMS negativo, mostrando a alta incidência desta doença entre os amputados. O acompanhamento dos resultados de reteste dos 25 pacientes com TEMS inicial negativo permitiu o estudo da instalação da cardiopatia isquêmica. No grupo acompanhado (25 pacientes), 12 pacientes (48%) apresentaram resultados positivos no reteste. Entretanto a incidência de resultados positivos no reteste é diferente (p&lt;0,05), entre pacientes protetizados (35%) e não-protetizados (100%). Considerando-se as limitações do estudo, conclui-se que existe uma grande incidência de cardiopatia isquêmica em pacientes amputados e que, provavelmente, o uso da prótese pode diminuir a incidência de cardiopatia isquêmica em pacientes amputados unilaterais e bilaterais no nivel da coxa
