Leishmaniose tegumentar e sua transmissão pelos phlebotomos

From all that has been ascertained up to now, it would seem that the transmission of tegumentary leishmaniosis scarried out by different species of Psychodids amongst them Phlebotomus papaiasii, Phlebotomus intermedius and Phlebotomus argentipes. The epidemiollogy, the geographic superpoition between the area in which these insects exist and the area in which the disease is found...

Sobre alguns casos de carcinoma primitivo do pulmão, do bronchio e da trachéa

1-Out of 1531 autopsies at Rio de Janeiro, Brazil, recorded in the Section of Pathology of «Instituto OSWALDO CRUZ», we found three cases of primary carcinoma of the lung, which gives the incidence of 0,195 per cent. They were not associated with tuberculos's and anthracos's was not marked. 2-The gross and microscopical features indicate that they are in reality primary cancers...

Alterações nucleares das cellulas do figado nas infecções de Macacus Rhesus e M. Cynomolgus pelo virus da febre amarella

In the liver of one Macacus rhesus injected by BEAUREPAIRE ARAGÂO with blood of one benign case of yellow fever and in which he described (1) symptoms and typical lesions similar to those obtained by STOKES, BAUER and HUDSON in M. rhesus injected with the African virus, it has been found (2) changes in the nuclei analogous to those refered to in herpes zoster, symptomatic herpes...

Ensaios de Mycologia

Morphologically the fungus reminds one of the Microsporum species of man. The microscopic elements are: the shape of the mycelia within the hairs, size and disposition of spores intercalar and terminal chlamydospores, simple clusters, hyphae, pectinate and denticulate elements. Of the 17 species of Microsporum described up to now, none can be identified with Microsporum...

Carcinoma epidermoide primario do estomago

Attention is called by the AA. to the rarity of this histological feature of gastric tumor verified and described, on post mortem examination, in a white Brazilian male, 57 years old. The tumor is located on the lesser curvature of the stomach under the appearance of a crateriform formation, 3.5 cms. in diameter, fast adhering to the pancreas. The esophagus and cardia are not...

Sobre o mechanismo de formação das hyperglobulias de origem toxica

Having verified a hyperglobulinogenous action of carbon tetrachloride, thymol and chenopodium essence when administered to man as vermifuges, we endeavoured to verify which is the mechanism of such hyperglobuliae. For this purpose, we chose two substances (chloroform and chloretorn), also hyperglobulinogenous, and dogs were used as experimental animals. We observed that, after...

Methodo para diagnostico do alastrim

Inclusion bodies of alastrim are quite consistent in their morphology and staining properties when studied in material from seven epidemies occurring in several States of Brazil (Pará, Minas Geraes, Rio de Janeiro, Districto Federal and São Paulo) from 1932 to 1937. Paranuclear or circumnuclear basophilie cytoplasmic bodies not stained by safranine, single or in pairs at opposite...

Dermatite verrucosa leprotica (Estudo de 3 casos)

The writer has discovered in Curupaity (National Leprosarium, Rio de Janeiro), three cases of verrucous dermatitis in C 3 type lepers. He suspected it to be an association of leprosy with Dermatilis verrucosa blastomycetica (Chromoblastocycosis) but various attempts to cultivate the fungus (Acrotheca or Hormodendrum Pedrosoi) responsible for the disease gave negative results and...

Pesquizas sobre a acção physiologica das toxinas bacterianas: I. sobre a actividade physiologica dos filtrados de culturas do bacillo coli. Reacções do intestino isolado e perfundido

The writers report experiments performed with filtrates of old cultures od colon bacilli upon the isolated and perfused rabbit gut. According to the experiments the writers suppose to exist one or more substances in the filtrates of old cultures of colon bacilli with physiological activity upon the isolated and perfused rabbit gut. Such activity is essentially characterised by a...

Intoxicação por veneno de cobra: necrose symetrica da cortex renal: uremia

In a mortal case of ophidism, in an individual 15 years old, bitten by a snake (Bothrops jararaca) on the external face of his right leg and who died 26 days after the accident, the AA. describe the pathologic-anatomical changes met with and the modifications of the metabolism put into evidence through chemical blood examinations. The main changes there existing are located in...

Ação do oxigenio sob pressão sobre a ação patogenica dos germens anaerobios

1) O² under pressure reduces the infectiosity of anaerobic bacteria. 2) This action of O² is increased with the lengthening of the time of exposure of the bacterial suspensions to the gas. 30 The reduction in infectivity is due to the death of the greater part of the bacteria submitted to the action of the O².

Fermentação da gelose pelas bacterias anaerobias

1 - Anaerobic bacteria of the Clostridium genus acidify mineral media without when agar is added. 2 - Acidulation results from the attack on the agar as a source of carbon. 3 - The quantity of CO² produced by the decomposition of the agar is approximately that obtained with soil bacteria as shown by Waksmann and Diehm working with hemicelluloses. Although galactone is less...

Rutura do baço na febre tifóide

A case of typhus levissimus or splenotyphus is reported whose death ocurred approximately at the beginning of the 2nd week as a consequence of rupture of the spleen and hematoperitoneum (2 liters). Acute perisplenitis and intracapsular hemorrhages as well as marked distention of the capsule pertinent to the extreme increase in volume of the organ in this stage of the disease are...

Alterações cutâneas do cão no Kala-Azar sul-americano

According to E. Chagas (1938), South-American Kala Azar is a widespread disease from the jungle, several cases being reported from North Brazil (Estado do Pará: Marajó Island, Tocantins and Gurupi river valleys; Estados do Piauí and Ceará: coast and hinterland). Other cases were found in Northeast Brazil (Estados de Pernambuco, Alagôas and Sergipe: coast and hinterland; Estado da...

Contribuição ao estudo da patologia da lepra murina

The A. reviewed the bibliography of pathology of murine leprosy. Out of 41 rats expontaneously infected with murine leprosy 39% had alopecia, especially on the back; 78% had subcutaneous infiltrations; 13 of them presented tumour-like grows, sometimes large as 5 cm. of diameter; eight animals had ulcerations varying from 1 to 15 in number; 11 had skin nodules; two presented...

Sobre Dipetalonema spiralis (Molin, 1860) (Nematoda, Filarioidea)

The authors give a description of Dipetalonema spiralis (Molin, 1860), based on two samples collected by the C. E. E. L. V. A. in the joints of the hands and feet of Choloepus didactylus (L.) at Piratuba, State of Pará, Brazil, both containing males and females. A study of the literature is made and original drawings are presented.

13ª Contribuição ao estudo dos Flebotomus (Diptera: Psychodidae): Flebotomus (Brumptomyia) travassosi Mangabeira, 1942

The A. describes the life history of Flebotomus (Brumptomyia) travassosi Mangabeira, 1942. The paper deals with the morphology of the eggs, the larvae in all stages, the pupae and the female. Also gives the differences between the 3 known species of that subgenus (avellari, travassosi and guimarãisi) pointing out the characters in common, principally the presence of only two...
