25. Alendronate of sodium, risedronate of sodium atorvastatin calcic and lovastatin in tibiais fractures in female rats with dexamethasone osteoporosis induced / Alendronato de sódio, risedronato sódico, atorvastatina cálcica e lovastatina na reparação de fraturas tibiais em ratas com osteoporose induzida pela dexametasona
This work consisted of a biological test with the objective to study the influences of the bifosfonates alendronate of sodium and sodic risedronate and of the statins calcic atorvastatine and lovasatatine in the recuperation of fractures of shin-bones of osteoporotics rats induced by the dexamethasone, in rats of the race Wistar, adults, weighing 250 20g.

26. Participação dos Quimiorreceptores Carotídeos sobre a Regulação Cardiovascular em Ratos Desnutridos
A large number of people die each year due to the intricate aftermath caused by cardiovascular diseases, such as arterial hypertension. Several experimental models have been developed in order to disclose the mechanisms that result in chronic increase of arterial pressure and malnutrition seams to be one of the factors contributing to this pathology. Our lab

27. Avaliação ecocardiográfica evolutiva do infarto do miocárdio em ratos jovens e adultos
INTRODUÇÃO: Nos corações de mamíferos ocorre multiplicação celular com maior intensidade em jovens do que em adultos. Desta forma, a recuperação espontânea dos cardiomiócitos após o infarto do miocárdio (IM) é mais evidente em animais jovens; entretanto, não se sabe se esta recuperação é acompanhada de melhora funcional. OBJETIVOS: Análise

28. 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

29. Effect of strenuous maternal exercise before and during pregnancy on rat progeny renal function
The effects of strenuous exercise before and during pregnancy on the renal function and morphological alterations of the progeny were determined in a study on female Wistar rats. This research was done based on a previous study carried out in our laboratory, which showed morphological alterations in rats submitted to this kind of exercise. As the form is rel

30. Dosagem, In Vivo, de Metabólitos Sanguíneos e Tissulares de Ratos Submetidos à Isquemia Renal e a Reperfusão Durante a Oferta de L-Alanil-Glutamina / Effects of L-alanil glutamine pre-treatment on the concentratios of lactate, pyruvate, glucose and ketone bodies in the intestinal tissues an blood of rats subjected to normothermic intestinal ischemia, in vivo
Renal tranplantation and other operations give rise to kidney ischemia/ reperfusion injuries that may interfere with the final outcome. The purpose of this study is to examine the effects of l-alanil-glutamine pre-treatment in rats subjected to renal ischemia/reperfusion. Twenty -four rats were distributed in 4 subgroups of 6 animals. Half an hour following

31. 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

32. c-Fos expression induced by electroacupuncture at the Zusanli point in rats submitted to repeated immobilization
In laboratory animals, acupuncture needs to be performed on either anesthetized or, if unanesthetized, restrained subjects. Both procedures up-regulate c-Fos expression in several areas of the central nervous system, representing therefore a major pitfall for the assessment of c-Fos expression induced by electroacupuncture. Thus, in order to reduce the effec

33. Susceptibility of spiny rats (Proechimys semispinosus) to Leishmania (Viannia) panamensis and Leishmania (Leishmania) chagasi
The role of Proechimys semispinosus as reservoir of Leishmania (Viannia) panamensis on the Colombian Pacific coast was experimentally evaluated. The susceptibility to L. chagasi also was assessed to determine the utility of this rodent as a model for studying reservoir characteristics in the laboratory. Wild-caught animals were screened for natural trypanoso

34. Biocompatibilidade de solventes utilizados no retratamento endodontico : estudo experimental em ratos
Re-treatment is the first option in case of failure of the endodontic therapy. To enable this process, it is essential to remove the pre-existing filling material of the root canal. The use of solvents facilitates this procedure and helps to avoid accidents. One of the properties required from these solvents is non-aggression to periapical tissues. The aim o

35. Allergy to laboratory animals: an epidemiological study.
A large cross sectional survey was carried out using a self administered questionnaire to examine the prevalence of laboratory animal allergy (LAA) and the factors associated with its development. Out of 5641 workers who were exposed to animals at 137 laboratory animal facilities in Japan, 23.1% had one or more allergic symptoms related to laboratory animals

36. Evaluation of Miconazole Therapy in Experimental Disseminated Candidiasis in Laboratory Rats
Miconazole, a broad-spectrum antimycotic agent with some antibacterial activity, has recently become available for experimental parenteral use in the United States. Its efficacy as an anticandidal drug was tested in adult Wistar rats. A previously established infectious dose of 5 × 106Candida albicans was intravenously injected into 250- to 300-g animals. T
