1. Comparison of different quantification methods for 18F-fluorodeoxyglucose-positron emission tomography studies in rat brains
OBJECTIVES: This study aimed to evaluate several methods to estimate glucose consumption in the male Wister rat brain as measured by PET. METHODS: Fourteen male Wistar normoglycemic rats were studied. The input function consisted of seventeen blood samples drawn manually from the femoral artery. Glucose uptake values were calculated using the input functio

2. Effect of bisacodyl on rats with slow transit constipation
The effect of bisacodyl on the treatment of rats with slow transit constipation (STC) was studied. Forty-five female Wister rats were divided into control group, STC group, and STC bisacodyl group. The immunohistochemical method was used to determine interstitial cells of Cajal (ICC) and the expression of c-Kit protein. Body mass and the number of defecation

3. Alternative animal model for studies of total skin thickness burns
Abstract Purpose: To present an alternative experimental model of third degree burn of easy reproducibility. Methods: Eighteen male Wister rats were randomly divided into three groups, 6 of which were allocated to each group. A soldering iron coupled to an aluminum plate was used to produce burn, at a temperature of 150ºC, with different exposure times pe

4. Propolis derivatives inhibit the systemic inflammatory response and protect hepatic and neuronal cells in acute septic shock
BACKGROUND: Severe pathogenic infection triggers excessive release of cytokines as part of the massive inflammatory response associated with septic shock. OBJECTIVES: To investigate the protective effect of caffeic acid phenethye ester (CAPE) against lipopolysaccharide (LPS) induced endotoxemia, hepatic and neuronal damage and the associated systemic inflamm

5. Cardioprotective effect of Bombax ceiba flowers against acute adriamycin-induced myocardial infarction in rats
The present study was designed to evaluate the cardioprotective potential of aqueous flower extract of Bombax ceiba L., Malvaceae (BC), on the basis of biochemical and histopathological parameters in Adriamycin (Adr) induced myocardial infarction in rats and to compare with vitamin E, a known cardioprotective antioxidant. Male Wister rats were used as in viv

6. Efeito do exercicio incremental exaustivo nas metaloproteinases 2 e 9 no musculo gastrocnemio de ratos Wistar / Effect of exhaustive incremental exercise in metalloproteinases 2 and 9 in the gatrocnemius muscle of rats
Os músculos esqueléticos são constituídos por fibras musculares e pela matriz extracelular. Em resposta ao exercício, o músculo apresenta a habilidade de transformar o estresse mecânico da contração muscular em adaptações de cunho biológico, a esse processo deu-se o nome de mecanotransdução. Embora pouco se saiba sobre a importância da matriz

7. Efeito da exposição crônica ao níquel nos testículos de ratos Wister adultos / Effect of chronic nickel exposure in the testes of Wistar adult rats
A toxicidade de um metal depende da sua capacidade inerente de afetar adversamente qualquer atividade biológica. Entre poluentes ambientais, o níquel, um metal pesado, merece destaque especial como um elemento potencialmente tóxico. A exposição aguda ou crônica ao níquel resulta em vários efeitos na reprodução, tendo como alvo o testículo, que é

8. Efeito da melatonina sobre parametros cardiovasculares em ratos portadores de hipertensão arterial pulmonar induzida por monocrotalina / Melatonin effect on cardiovascular parameters in disabled pulmonary arterial hypertension monocrotaline induced rats
A Hipertensão Arterial Pulmonar (HAP) é uma patologia caracterizada pelo aumento da resistência dos vasos pulmonares, aumento na pressão Arterial pulmonar e hipertrofia do ventrículo direito, prejudicando as trocas gasosas alveolares e a função cardíaca. Por outro lado, a melatonina (N-Acetil-5- metoxitriptamina), o principal hormônio produzido pela

9. Differences in functional and structural properties of segments of the rat tail artery
The investigation of resistance vessels is generally costly and difficult to execute. The present study investigated the diameters and the vascular reactivity of different segments of the rat tail artery (base, middle, and tail end) of 30 male Wister rats (EPM strain) to characterize a conductance or resistance vessel, using a low-cost simple technique. The

11. Efeito da adrenalectomia na evolução da doença de Chagas experimental em ratos wistar machos infectados com cepa Y de Trypanosoma cruzi
Glucocorticoids are therapeutic agents widely used for auto-immune diseases. The number of papers concerning to the actions of glucocorticoids are still not well stabilished. The aim of this work is to evaluate the interactions between adrenal glucocorticoids and its effects on the development of experimental chagasic infection in male Wistar rats infected w

12. Effects of chronic hyperprolactinaemia on experimentally induced thirsts in male rats.
Chronic hyperprolactinaemia was induced in ten male Wistar rats by subcutaneous injection of tissue fragments of the MtTW 15 prolactin-secreting adenoma. Serum prolactin was elevated significantly by 3 weeks after adenoma inoculation and increased progressively thereafter. An additional ten Wister-Furth rats were inoculated with the MtTW 15 adenoma and an eq
