Possibilidades de transmiss?o e vias de inocula??o da lepra murina em ratos e outros animais
Linhares, Herminio;
Memórias do Instituto Oswaldo Cruz , 1943, DOI: 10.1590/S0074-02761943000300003
Abstract: 1) the a. reviews the routes of natural transmission of rat leprosy and the experimentally induced disease. 2) the infection in the natural disease must be made by contact with an infected rat or through the gastro-intestinal route by eating infected tissue. 3) they were found acid-fast bacilli in lice (polyplax spinulosa) caught on rats dying of leprosy; but it was impossible to obtain cultures in l?wenstein medium, from these lice. 4) rat leprosy emulsion introduced into the stomach, may infect rats. five rats fed with infected material became infected. 5) after subcutaneous or intraperitoneal inoculation there were obtained infection in almost 100% of cases. 6) it was possible to infect didelphis aurita after inoculation of infected rat material. these animals most likely are more susceptible to rat leprosy than to human leprosy. 7) it was possible to infect chicks by inoculation in chest muscle, by intraperitoneal injection and by gastrointestinal route. 8) it was possible to infect pigeon by inoculation in chest muscle and by intravenous inoculation.

Abstract: 1. french neurotropic, asibi and vaccine (17d) virus, infect young mice (21 days) when instilled in the nostrils, killing them with symptoms of encephalitis or developing immunity. 2. french neurotropic virus and asibi (and perhaps vaccine virus), when instilled in the ear of young mice, may infect them producing development of immunity. 3. after instilation in the scarified cornea of young mice, french neurotropic virus, asibi and perhaps vaccine virus, may produce infection. the cornea being, however, whole it has not been able to infect mice. 4. french neurotropic virus, asibi, vaccine, asib egg i and egg iii introduced into the stomach, may infect young mice, causing e fatal encephalitis or rendering them immune. 5. it is possible to infect mice 0-6 days old by simple deposition of virus or rubbing the suspension on the whole and scarified skin.
Verifica??o da lepra murina na cidade do Rio de Janeiro: sua distribui??o geográfica e considera??es endemiológicas
Linhares, Herminio;
Memórias do Instituto Oswaldo Cruz , 1942, DOI: 10.1590/S0074-02761942000300010
Abstract: 1 ? rat leprosy hás been found in the city of rio de janeiro. among 10.000 rats examined there were 37 that presented characteristic lesion of rat leprosy disease, out of which 32 were rattus norvegicus (86,5%), 3 rattus alexandrinus (8,1%) and 2 mus musculus (5,4%). 2 ? the disease was observed mostly in adult rats, i.e 94,6%; the rest being observed in young ones. 3 ? probably the sex has not influence upon the infection, but the a. has found 24 males and 13 females affected, a ratio of 1.8:1. 4 ? the glandular form of the disease was the most prevalent being observed in 25 rats, 9 rats showed the musculo-cutaneous form and 3 the mixed form. this one was noticed only in advanced cases of the infection.

Abstract: 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 splenomegaly and two others small nodules upon the surface of the spleen; five had microabcesses on the liver; two had pneumonia and two others showed microcabcesses on their lungs. the other organs were macroscopically normals. histopathological studies were made with materials of natural and experimental rat leprosy disease. granulomata were seen on sections of their skins, lumph nodes, spleens, bone marrows, livers, lungs and kidneys. the testicles were rarely envolved. the granulomatous tissues are formed by mononuclear cells or by large plae cells resembling epithelioid celss, in which there were numerous bacilli. the infections process become localisated by long time in the lumph nodes. rat leprosy by its nature and probably origin of the affected cells suggest a primordially disease of the reticulo-endothelial system.
Transmiss?o de imunidade antiamarílica da m?e aos filhos, em camondongos

Memórias do Instituto Oswaldo Cruz , 1943, DOI: 10.1590/S0074-02761943000200008
Abstract: 1. females rendered immune actively and passively against yellow fever virus may transmit protective antibodies to their young ones. 2. mice acquire immunity through the placenta and principally after birth by ingestion of milk of an immune female. 3. the virus can not be transmitted by either of the two ways. 4. the immunity transferred through the placenta disappears much more rapidly than immunity transmited by milk. 5. young ones from a normal female acquire immunity rapidly if fed by an immune female. 6. mice of more than 10 days absorb antibodies just as well as during the first days of their birth, and the milk carries with it protective substances during the whole suckling period.
Inocula??o de virus amarílico em gatos jovens
Linhares, Herminio;
Memórias do Instituto Oswaldo Cruz , 1943, DOI: 10.1590/S0074-02761943000200009
Abstract: 1. young cats inoculated intracerebrally with relatively large doses of neurotropic or viscerotropic virus, and intraperitoneally with visceropic virus fail to show circulating virus up to 12 days post-inoculation. 2. such cats also fail to show symptoms referable to the virus. it was impossible to isolate virus from the brains of inoculated cats dying in the course of the experiments, and histological examinations of the brains failed to show escephalitis (only one case with toxic encephalitis). 4. the development of serological immunity after 30 days was observed in all but two of the cats inoculated intracerebrally or intraperitoneally with neurotropic virus; with asibi strain, only two positive results were obtained, with the intracerebral route. 5. young cats are relatively unsusceptible to yellow fever virus, only giving the reaction of immunity.
Suscetibilidade de pintos ao virus amarílico neurotrópico

Memórias do Instituto Oswaldo Cruz , 1943, DOI: 10.1590/S0074-02761943000200011
Abstract: 1. after 80 serial passages from brain to brain of chicks, neurotropic virus fails to show essential modifications in the behaviour of the virus in mice or chicks. 2. chicks are susceptible by intracerebral, intraperitoneal and intradermal route, showing high levels of circulating virus and become immunes when inoculated during the first days after birth. but, circulating virus varies, however, in inverse ratio to age. it does not seem possible to infect chicks by gastric route. 3. during first days virus may be found, occasionally in the lungs, liver, spleen and kidneys; some days afterwards, no chicks showed virus in other organs than brain, in which virus persists up to 10th day post-intraperitoneal inoculation and up to 15th day after the intracerebral inoculation, and perhaps till later. we have however, not been able to isolate the virus from excretions. 4. there does not seem to be any difference in susceptibillity to the yellow fever virus, on chicks with b avitaminosis. 5. detectable immune bodies appear by 10-11 day after intraperitoneal and intracerebral inoculation, at time, that many of some chicks still have virus in the brain. 6. age has a marked influence on the development of immunity, in chicks inoculated by intraperitoneal route. 7. the multiplication and circulation of virus after intradermal inoculation of 50 to 160 m.l.d., renders possible to suggest that infected mosquitoes can difuse the virus among chicks and, perhaps, to other birds, a few days old.
The Estimates L1-L for the Reduced Radial Equation of Schr?dinger  [PDF]

Advances in Pure Mathematics (APM) , 2019, DOI: 10.4236/apm.2019.95023
Abstract:
Estimates of the type L1-L for the Schrödinger Equation on the Line and on Half-Line with a regular potential V(x), express the dispersive nature of the Schrödinger Equation and are the essential elements in the study of the problems of initial values, the asymptotic times for large solutions and Scattering Theory for the Schrödinger equation and non-linear in general; for other equations of Non-linear Evolution. In general, the estimates Lp-Lp' express the dispersive nature of this equation. And its study plays an important role in problems of non-linear initial values; likewise, in the study of problems nonlinear initial values; see [1] [2] [3]. On the other hand, following a series of problems proposed by V. Marchenko [4], that we will name Marchenko’s formulation, and relate it to a generalized version of Theorem 1 given in [1], the main theorem (Theorem 1) of this article provides a transformation operator W?that transforms the Reduced Radial Schrödinger Equation (RRSE) (whose main characteristic is the addition a singular term of quadratic order to a regular potential V(x)) in the Schrödinger Equation on Half-Line (RSEHL) under W. That is to say; W?eliminates the singular

Quantified Control and the Mass Production of “Psychotic Citizens.”
Grahame Lock,Herminio Martins
EspacesTemps.net , 2011,
Abstract: In the bygone world (a complex, messy, contradictory world), different kinds of institutions embodied various, incommensurable kinds of value. Academic value was not to be identified with artistic value, nor artistic value with monetary value, and so on. But in our brave new world, it seems that a single final criterion of value is recognized: a quantitative, economic criterion. All else is no more than a means. And there is a single method for ensuring that this criterion is satisfied: ...
