Pathogenia da anemia na Ancylostomose: III - modificações hematicas e organicas, provocadas pelas simples eliminação do Ancylostomo e do Necator, em individuos fortemente anemiados

Estudamos sob um ponto de vista hematologico, 10 casos puros de Ancylostomose, durante um largo tempo. Um dos doentes foi observado por mais de 2 annos, justificando esta larga observação a segurança que almejavamos alcançar de que a simples eliminação dos helminthos não trouxesse nenhuma modificação hematica, mesmo longiqua. O estudo hematologico constou de 200 exames rotineiros (determinação do numero de globulos, da taxa de Hb., do hematocrito, e, em muitos casos, da taxa dos reticulocytos e exame de esfregaços), praticados em todos os doentes, e de determinações da resistencia globular e outras pesquizas hematologicas praticadas em alguns delles. A grande parte do estudo constou de uma minuciosa (observação sanguinea e clinica dos casos, antes e após administração de vermifugos, até uma completa eliminação dos parasitos intestinaes. Procurou-se averiguar tambem, por meio da administração de diversas dietas, a influencia sobre o quadro hematico da dita eliminação combinada ao effeito de differentes factores nutritivos contidos nestas dietas. Procuramos verificar os phenomenos regenerativos com a administração de ferro, e tambem tivemos opportunidade de observar a marcha da anemia, e assim confirmar resultados que já publicamos. Os resultados mostraram a importancia da absorpção dos medicamentos vermicidas empregados, e por isso focalizamos varios factos similares, procurando relacional-os com aquelle aqui verificado. Discutimos a seguir o methodo therapeutico á luz dos resultados apresentados, e nos referimos á importancia destes na elucidação correcta de pathogenia da doença.

Efficiency and environmental regulation: a 'complex situation'

Production of desirable outputs is often accompanied by undesirable by products that have damaging effects on the environment, and whose disposal is frequently regulated by public authorities. In this paper, we compute directional technology distance functions under particular assumptions concerning disposability of bads in order to test for the existence of what we call ‘complex situations’, where the biggest producer is not the greatest polluter. Furthermore, we show that how in such situations, environmental regulation could achieve an effective reduction in the aggregate level of bad outputs without reducing the production of good outputs. Finally, we illustrate our methodology with an empirical application to a sample of Spanish tile ceramic producers.

Ensaios terapêuticos com penicilina: III - Bouba (Framboesia, pian, yaws): (continuação): penicilina de procedência americana, empregada em doses baixas também cura aparentemente esta enfermidade

Five patients of yaws were treated with american Penicillin (Squibb, Winthrop and Lilly), in small dosis. The treatment has been performed, using 200 Oxford units each 4 hours. The total amount of units "per" subject, has varied from 24.000 to 54.000. A complete disappearence of the external lesions was obtained between the 12th and the 25th day of treatment.

Embedding theorems of funcitional classes, III

In this paper we obtain the necessary and sufficient conditions for embedding results of different function classes. The main result is a criterion for embedding theorems for the so-called generalized Weyl-Nikol'skii class and the generalized Lipschitz class. To define the Weyl-Nikol'skii class, we use the concept of a (λ,β)-derivative, which is a generalization of the derivative in the sense of Weyl. As corollaries, we give estimates of norms and moduli of smoothness of transformed Fourier series.

Empiricism in ecological economics: a perspective from complex systems theory

Economies are open complex adaptive systems far from thermodynamic equilibrium, and neo-classical environmental economics seems not to be the best way to describe the behaviour of such systems. Standard econometric analysis (i.e. time series) takes a deterministic and predictive approach, which encourages the search for predictive policy to ‘correct’ environmental problems. Rather, it seems that, because of the characteristics of economic systems, an ex-post analysis is more appropriate, which describes the emergence of such systems’ properties, and which sees policy as a social steering mechanism. With this background, some of the recent empirical work published in the field of ecological economics that follows the approach defended here is presented. Finally, the conclusion is reached that a predictive use of econometrics (i.e. time series analysis) in ecological economics should be limited to cases in which uncertainty decreases, which is not the normal situation when analysing the evolution of economic systems. However, that does not mean we should not use empirical analysis. On the contrary, this is to be encouraged, but from a structural and ex-post point of view.

Estudo sôbre Flebotomus no Vale Amazonico Parte III - Descrição de F. servulolimai e F. wilsoni: (Diptera-Psychodidae)

Duas espécies novas de flebotomus da Região Amazônica são descritas sob os nomes de F. servulolimai e F. wilsoni. Ambas apresentam fêmures posteriores inermes, tufo proximal de cerdas no segmento basal da gonapófise superior, segmento distal da mesma gonapófise com quatro espinhos e gonapófise mediana inerme com dilatação na face superior.

Ensaios terapêuticos com penicilina V-Bouba (Framboesia, pian, yaws): I - Dose curatina mínima: II - Redução do número de injeções diarias: III - Redução de tempo de tratamento pelo emprêgo de doses mais elevadas

This report belongs to the series of works carried out Oswaldo Cruz Ins¬titute, on the treatment of treponematosis with penicillin. The present report deals with investigations performed in order to ascer¬tain the following points: 1) the mininal curative dosis for the initial lesions of yaws; 2) the effect of reduction of the number of injections each day, to verifie the possibility of application of penicillin in the prophylaxis of yaws in rural zones; 3) reduction of the time of treatment by application of high dosis. 1) With dosis of 150 and 100 Oxford units each four hours, clinical reco¬very was obtained after 17 days of treatment. With 50 O.u. during 40 days clinical recovery was not obtained. 2) a) With 3 injections of 400 O.u. each day (6,12 and 18 hoórs clocks) clinical recovery was obtained after 14 to 16 days; b) with 2 injections of 400 O.u. each day (6 and 18 hoors clocks), clinical recovery was obtained after 16 to 23 days; c) with 1 injection of 1.600 and 3.200 each day, clinical recovery was obtained after 30 and 20 days. 3) With dosis of 33.3 and 46.7 O.u. by each kilo of weight each four hours, during 15 days, clinical recovery was obtained more or less in 25 days. The same result was obtained with the dosis of 61.5 and 166.7 O.u. by each kilo of weight, each four hours, during 4 days. But with 100.000 O.u. in fine dosis of 20.000 in a day ou by, clinical recovery was not obtained.

Notas sôbre Tabânidas brasileiros: III. Fidena adnaticornis n. sp

Fidena adnaticornis n. sp. is described from female specimens. It closely resembles Fidena besckii (WIED. ), 1828 and indeed more closely Fidena soledadei (LUTZ), 1911. It can be distinguished from both by the antenna which are so close together that the distance between their basis is less that the width of the first antennal segment; also by the prevalence of yellow hairs on the coxae. In F. soledadei and chiefly in F. besckii the antennae an evidently more separated; they have also few yellow hairs limited to the base extremity of the coxae with prevalence of brown or black hairs. In F. besck the prealar hairs are predominantly yellow ones and there exist yellow hair around the edge of the scutellum, which does not occours in F. adnaticorn and in F. soledadei. In the abdomen the following areas, covered by whit hairs are more extensive in F. besckii: the mid row of white patches on the sternites is more conspicuous and involves the fifth segment; on the sternites instead of stripes the hairs form bands somewhat broader at the middle the respective segment, they may even form triangles with the base as with as the whole segment. Both cotypes of F. soledadei have the hairs damages but, at least, in the 1+2 sternites the areas covered by the white hairs see to be larger than in F. adnaticornis; they have also a higher frons: index : = 2.9.

Anfíbios Anuros da coleção Adolpho Lutz: III - Hyla claresignata Lutz & B. Lutz, 1939

Hyla claresignata Lutz & Lutz, 1939, is a large species apparently not closely allied to the other known Brazilian hylas. It is characterized by the very small tympanum; the head is short and the snout rounded; the legs are long, the hands and feet unusually large, the latter extensively webbbed. The specific name is derived from the insular, irregular, or roughly triangular, dark spots, with a light halo, found mostly in the dorso-lateral region and on the legs. It belongs to the rain-forest fauna of the Marítime Range. The adult is a bromeliad-dweller and the tadpole rhyacophilous. DESCRIPTION. Vomerine teeth in two separate, oblique, groups, behind the large choanae, parallel to the posterior half of their inner border. Tongue entire, short, very broad and hardly free behind. Snout short, rounded, with distinct canthus rostralis and gradually sloping loreal region. Eye very large and prominent, its horizontal diameter almost equal to the distance between its anterior corner and the tip of the snout. Tympanum very small, less than one third of the diameter of the eye, but distinct, partly covered by a short, heavy ridge. Lateral fingers less than one third webbed; fourth finger slightly longer than the second, just reaching the base of the disk of the third; subarticular tubercles well developed; an angular pollex rudiment, more noticeable in the males. Toes almost completely webbed, the edge of the web inserted at the base of the disk on the third and the fifth; an inner metatarsal tubercle. Skin smooth above, granular beneath, on the throat minutely so. No dermal appendage on the hell. Habit robust, head broader than long, body rather heavy, slightly narrowed in the postaxillary region. Legs long, the tibiotarsal articulation reaching beyond the tip of the snout when adpressed. Type (female): 61 mm. (Fig. 1.) DIAGNOSIS of TADPOLE (by G. Orton). "A large specialized, mountain-stream tadpole, with wide head an elongated, flattened snout, greatly enlarged lips and high tooth formula. Eyes dorsal. Spiracle sinistral, projecting, situated far back on side. Anus dextral. Tooth formula 8/12 to 9/14 in fully grown larvae. Tail with a prominent, vertical dark band across musculature and fins; a second concentration of dark pigment near tip of tail, may or may not form a similar but narrower band. Maximum known total length: 60mm.; head and body length 25mm. (Figs. 6 e 7). For further details see Lutz & Lutz, 1939 and Lutz B. & Orton G. 1946.
