1. Astaxanthin protects against hearing impairment in diabetic rats
Abstract Objectives: Diabetes Mellitus (DM) causes an increase in oxidative stress that leads to deterioration in auditory functions. Astaxanthine (AST) is known to have strong antioxidant effects. In this study, the aim is to investigate the effect of AST against hearing loss that is due to DM. Methods: This study is an experimental animal study. The stud

3. Laboratory evidence for the hematopoietic potential of Beta vulgaris leaf and stalk extract in a phenylhydrazine model of anemia
This study was designed to provide laboratory evidence supporting the hematopoietic effect of Beta vulgaris (beet) leaf aqueous extract in phenylhydrazine-induced anemia model in albino rats. Extraction of the leaves/stalks was done by maceration in 30% hydro-ethanol for 48 h. An intraperitoneal injection of 20 mg/kg phenylhydrazine was applied for two conse

4. Local application of statins in the treatment of experimental periodontal disease in rats
Abstract Objective The objective of this study was to evaluate the local effects of statins as adjuvants for treatment by scaling and root planing (SRP) of periodontal disease induced in rats. Material and Methods Ninety rats were used in the present experiment. Periodontal disease was induced in all animals using a cotton thread placed in the left first

5. Estudo histológico dos tecidos conjuntivo e osteóide em enxertos ósseos com polímero de mamona : estudo experimental em ratos / Histological study of connective and osteoid tissue in bone grafts with castor oil polymer : experimental study in rats
The reconstruction of great bone loss defects represents a challenge for reconstructive surgery. To reconstruct these defects it is necessary to create conditions to stimulate new bone formation, in order to block the connective healing tissue growth towards the bony defect, which blocks the osteogenesis. The autogenous grafts are inconvenient, because they

6. Efeito ansiolítico do ondansetron, antagonista dos receptores 5-HT3, injetado na amídala de camundongos submetidos à exposição e reexposição no labirinto em cruz elevado
Against of stimuli that are dangerous, animals manifest defense reactions that cause fear and anxiety. These stimuli activate the serotonergic system, which sends projections to structures involved in defense mechanisms such as the septum, hypothalamus, hippocampus, amygdala and periaqueductal gray modulates the behavioral changes that can be characterized a

7. Função reprodutiva em ratos machos obesos por consumo de dieta hipercalórica / Reproductive function in obese male rats by consumption of hypercaloric diet
O sobrepeso e a obesidade estão aumentando rapidamente, tornando-se uma epidemia mundial. Estas duas condições podem ser definidas simplesmente como o acúmulo excessivo de gordura nos adipócitos, células do tecido adiposo responsáveis pela síntese e liberação de leptina, um hormônio protéico cuja principal ação é inibir o apetite e estimular o

8. Study of the alterations in the development, behavior and cerebral biochemistry of male rats exposed to the environmental atmospheric pollution in the intra-uterine phase / Estudo das alterações no desenvolvimento, no comportamento e na bioquímica cerebral de ratos machos adultos expostos à poluição atmosférica ambiental durante a fase intra-uterina e o período de lactação
Experimental studies done at our laboratory demonstrated that the inhalation of residual oil fly ash by the adult rats decreased motor activity of the animals in the open-field test. Additionaly, we showed that rats which inhalated residual oil fly ash preserved its habituation capacity. In this study, oxidative stress in striatum and cerebellum might be the

9. 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

10. AVALIAÇÃO DOS EFEITOS DO ESTRESSE NUTRICIONAL PROMOVIDO PELO DÉFICIT PROTÉICO PÓS-DESMAME SOBRE O SISTEMA CARDIOVASCULAR DE RATOS
This work focuses on the nutritional stress caused by post-breast-feeding protein deficiency in rats. Stress-related hormones may alter homeostasis in several body systems; among them, the cardiovascular system was chosen for our present studies. Early works in our laboratory have shown that, in rats, the post-breast-feeding protein malnutrition leads to an

11. Analise proteomica de soro de ratos em diferentes situações de exercicio e uma experiencia de pesquisa em ensino / Serum proteomic analysis of rats in differents exercise situations and an experience in teaching
The adaptive response to a training program is related to an intensive process of protein synthesis, which cumulative effect of multiple sessions of exercise leads to muscle phenotypic alterations and increases different physical capacities. For such adaptation an appropriate time for recovery between stimuli is required. A continuous process of intensified

12. PressÃo arterial, frequÃncia cardÃaca e sua modulaÃÃo autonÃmica em ratos malnutridos em diferentes idades
Undernutrition during human development is one of the principal causes of various systemic alterations and is characterized as one of the greatest public health problems in underdeveloped countries. Using an experimental model that reproduces in rats a type of human malnutrition found in the Northeast of Brazil, we use a multideficient hypoproteic and hyperc
