1. Evaluating the best time to intervene acute liver failure in rat models induced by d-galactosamine
ABSTRACT PURPOSE: To describe an animal model for acute liver failure by intraperitoneal d-galactosamine injections in rats and to define when is the best time to intervene through King's College and Clichy´s criteria evaluation. METHODS: Sixty-one Wistar female rats were distributed into three groups: group 1 (11 rats received 1.4 g/kg of d-galactosami

2. Laboratory animals and respiratory allergies: The prevalence of allergies among laboratory animal workers and the need for prophylaxis
OBJECTIVE: Subjects exposed to laboratory animals are at a heightened risk of developing respiratory and allergic diseases. These diseases can be prevented by simple measures such as the use of personal protective equipment. We report here the primary findings of the Laboratory Animals and Respiratory Allergies Study regarding the prevalence of allergic dis

3. Estudo de um sistema de análise de preferências climáticas para animais convencionais de laboratório por tecnologia de ventilação microambiental e avaliações biológicas. I. Avaliação da eficiência de um protótipo, para o estudo de parâmetros ambientais, resultados parciais verificados em ratos (Rattus norvegicus) / A climatic chamber employing Intracage Ventilation System to evaluated house condition of laboraroty animals and to biological assays in thermoregulation studies. Partial evaluation in rats (Rattus norvegicus)
Projects concerned with laboratory animals facilities usually adopt narrow range of ventilation and climatization variables to assure the define ambient. Such projects are concerned to the animal room (macro-environmental ambient) and this technology have a limitated operation to reach the micro-environmental (animal cages) ambients. The development of the i

4. Destilado da desodorização do oleo de soja como suplemento de vitamina E / Soybean oil deodorizer distillate as a vitamin E supplement
Increased use of industrial waste and byproducts fits the need of industry to comply with environmental rules. The substitution of natural products for artificial ingredients has gained worldwide attention in the food, pharmaceutical and other industries. These facts justify the study on the utilization of Soybean Oil Deodorizer Distillate (SODD) as tocopher

5. Efeito do ciclamato de sódio sobre o pâncreas exócrino fetal de ratos: estudo cariométrico e esterelógico.
Cyclamate, a sweetening substance derived from N-cyclo-hexyl-sulfamic acid, is largely used as a non-caloric artificial edulcorant in foods and beverages as well as in the pharmaceutical industry. This study aims at evaluating different karyometric and stereological quantitative parameters in the exocrine pancreas of rat fetuses . In five pregnant rats, a do

6. Artropodes associados as carcaças de pequenos roedores expostas em area de formação vegetal secundaria no municipio de Campinas, SP / Arthropods associated with small rodent carcasses exposed in a secondary wood area in the municipality of Campinas, SP
Although studies of the post-mortem fate of human corpses are of forensic interest, and in natural environments large animals become available to insect colonization soon after death, the fate of the vast number of small carcasses in some habitats, as well as the parameters that lead this process, are not objective of important investigations. Due to this si

7. TÃcnicas de Interferometria Ãptica aplicada à medicina, odontologia e comunicaÃÃes Ãpticas
In the work described in this thesis, we used two different interferometric techniques, the coherent optical frequency domain reflectometry (COFDR), and the optical coherence tomography (OCT). Both techniques are based on the Michelson interferometer. They were applied to optical communications and to medical and dentistry imaging. We will give a general des

8. Esvaziamento gastrico de liquidos em ratos com infarto experimental do miocardio
The Gastric Emptying (GE) is the transition of food from the stomach to the upper small intestine, and could be modify by haemodinamics changes as occur in myocardial infarction (MI). Therefore, the object of the present investigation was to study the effect of acute myocardial infarct on rat gastric emptying and the effect of bacterial lipopolysaccharide in

9. Propagation of Korean hemorrhagic fever virus in laboratory rats.
Korean hemorrhagic fever virus (KHFV) has been adapted to the Wistar and Fisher strains of rats. Infection was detected by the appearance of specific antigen in the lung tissue of the infected rats at 14 to 64 days after inoculation and by the appearance of circulating antibodies in ther serum which reacted specifically with KHFV antigen in the lungs of infe

10. A method for determining the dermal toxicity of pesticides
Noakes, D. N., and Sanderson, D. M. (1969).Brit. J. industr. Med.,26, 59-64. A method for determining the dermal toxicity of pesticides. A method is described for the measurement of the percutaneous LD50 of a pesticide, using the laboratory rat as a test animal. The results obtained by this method on a selection of pesticide chemicals are tabulated and discu

11. Studies in laboratory animals to assess the safety of anti-inflammatory agents in acute porphyria.
The safety of various anti-inflammatory drugs in acute porphyria was assessed by examining their effect on rat hepatic haem synthesis. Azapropazone, chloroquine, and gold increased delta-aminolaevulinic acid (ALA) synthase activity, indicating that they are liable to precipitate porphyric crises. Aspirin, ibuprofen, indomethacin, ketoprofen, flurbiprofen, ph

12. Improved rat model of Pneumocystis carinii pneumonia: induced laboratory infections in Pneumocystis-free animals.
An immunosuppressed rat model of Pneumocystis carinii pneumonia is described that utilizes simple, noninvasive intratracheal (i.t.) inoculation of cryopreserved parasites and results in development of severe P. carinii pneumonia within 5 weeks. This is an improvement over the most commonly used models of P. carinii pneumonia that rely on immune suppression t
