Uso de la inmunohistoquímica como herramienta epidemiológica para el diagnóstico de rabia bovina a partir de casos no conclusivos

Objective. Identify the rabies virus in cases of nervous disease archived in the laboratory with diagnosis of nonspecific encephalitis. Materials and methods. Twelve samples of bovine brain suspected of rabies, were processed by indirect immunoperoxidase technique using polyclonal antibodies against the viral agent. Results. Was demonstrated the presence of viral antigens in three cases in the form of small aggregates in the cytoplasm of neurons, with a pattern of round or oval and a variable number of viral inclusion bodies. We discussed the importance of the results in Colombia, the usefulness of the technique in the difficult conditions for sending samples to the laboratory, plus the possible relationship of the negative cases with bovine herpesvirus 5. Conclusions. The use of immunohistochemical technique to demonstrate rabies virus antigens in formalin fixed bovines tissues can help in the construction of an epidemiological map of rabies disease in Colombia and may reduce the high under-diagnosis of diseases of the nervous system of cattle, reported in some regions.

Uso de la cefalexina en infecciones piogenas de la piel: comparacion de dos esquemas terapeuticos

50 patients with pyogenic infections of the skin were divided into 2 groups and treated with cephalexin. Group A, 26 patients, received 500 mg/12 hours; Group B, 24 patients, 250 mg/6 hours. Clinical diagnosis was substantiated by bacteriologic study of cultures to identify the organism and determination of its susceptibility to the drug. Group A showed 91%, group B 95%; satisfactory results. No side-effects were noted. Either form of dosage was effective in the treatment of pyogenic infections of the skin.

Un uso de la historia en la enseñanza de la didáctica de la Física

It is shown the result of design, implement and analyze an exercise for teaching of Didactics of Physics, based on the use of History of Science as an information resource and point of discussion. We start with two assumptions: (1) currently, in the international level there is a research field that studies the use of History, Philosophy and Epistemology of sciences on education of teachers, which present that this field allows to treat contents of Physics in nontraditional ways, that is to say, beyond to the mathematician vision; (2) one of the dimensions that should be worked on education of teachers, specifically in education for teaching, must be, the (re) connaissance of their disciplinary knowledge, through metacognitive exercises, for which History provides appropriate resources. In order to involve the future teacher in a metacognitive activity that would allow (re) visit some of their knowledge of Physics, we developed an exercise based on research results about the history of the light concept. We analyzed the potentialities of this exercise to educate for teaching.

Capacidad de uso de la tierra en la cuenca de la Corriente del Lobo, Itatinga, São Paulo, Brasil

The objective of the research was to define the classes of use capacity of 2403.25 ha in the basin of the Corriente del Lobo - Itatinga (SP), (22°03'56" to 22°59'12" of latitude S and 48°38'47" to 48°41'25" of longitude W Gr.). The soil use capacity was obtained by using the SIG IDRISI 32 crossing the documents of steepness and soils and the document of judgment of classes of soil use capacity and of the utilitarian rising of the physical milieu. The classes and subclasses areas of use capacity presented the following values: IIIa - 68.60 ha (2.85%), IIIe,s - 1919.15 ha (79.86%); IIIe - 210.60 ha (8.76%); IVe - 3.38ha (0.14%); IVe,s - 157.42 ha (6.55%) and VIe,s - 44.10 ha (1.84%). The lands of the basin were distributed in three classes (III, IV and VI) and six subclasses but the biggest extension (79.9%) belonged to the subclass IIIe,s. The modules of the IDRISI allowed to discriminate, mapping and to quantify quickly the soil use capacity of the areas of classes and subclasses in the basin.
