Responses to anaesthesia with essential oil (EO) of Aloysia triphylla (135 and 180 mg L−1) tricaine methanesulfonate (MS222) (150 300 were assessed in silver catfish. Exposure the anaesthetics elicited a stress response species. In case MS222, it was displayed as release cortisol into bloodstream, elevation hematocrit plasma ion loss. The EO presented cortisol-blocking properties, but increased haematocrit disturbances hydromineral balance observed. Liver antioxidant/oxidant status...
Anaesthetic substances are necessary to reduce fish stress during aquaculture activities. The objectives of this study were: (i) determine the efficacy essential oils (EOs) Myrcia sylvatica (EOMS) and Curcuma longa (EOCL) as anaesthetics for Colossoma macropomum (ii) evaluate effects rapid anaesthesia long-term sedation (6 h) with these oils. Therefore, main primary indicator (cortisol) secondary factors (biochemical indices, hepatic metabolism, oxidative biomarkers) were measured. Sedation...
We examined the effects of dietary supplementation for 21 days with different levels (0, 0.25 and 2.0 ml/kg) Aloysia triphylla essential oil (EOAT) on silver catfish (Rhamdia quelen). Cortisol were lower in fish fed EOAT at ml/kg diet, lactate those both doses. Glucose, alanine aminotransferase, aspartate aminotransferase triglyceride did not vary between groups. The biomarkers oxidative stress, thiobarbituric acid-reactive substances, lipid hydroperoxide, superoxide dismutase, catalase...
The effects of dietary supplementation graded level (0, 0.25, 0.5, 1.0, and 2.0 ml/kg diet) Citrus aurantium essential oil (EOCA) on the growth, metabolic, oxidative parameters silver catfish (Rhamdia quelen) were investigated in a 60-day growth trial. Fish fed with ml EOCA per kg exhibited significantly better performance than those control diet. Glucose, lactate, protein levels liver muscle altered by addition EOCA. Hepatic lipid peroxidation levels, measured using thiobarbituric acid...
The effects of diet supplemented with Myrcia sylvatica essential oil (EOMS) on growth and stress tolerance to different stocking densities were assessed in Sparus aurata. Initially, three experimental groups established: (i) control, (ii) 1.0 (iii) 2.0 ml EOMS/kg dry feed. After 90 days, nine fish per group anaesthetized, weighed sampled for metabolic analysis. remaining divided into two conditions: low (LD—5 kg/m3) high (HD—40 densities, constituting a final setup six treatments. 22 10...
The aim of this study was to determine oxidative stress parameters in the liver and gill Brazilian flounder juveniles (307.0 ± 16.0 g 30.0 4.0 cm) submitted different water temperature (17.1, 23.0 28.8ºC) for 72 h maintained at salinity 25‰. After acclimation 7 days, 23ºC, fish were transferred 200 L tanks containing seawater (salinity 25‰) 28.8ºC (heat shock), 17.1ºC (cold shock) or 23.0ºC (control), five replicates (five tank-1). sampled collection occurred 0 (pre-challenge), 3, 24, 48...
The effect of parboiled rice (PR) and white (WR) diets on oxidative stress (OS) parameters was investigated in the kidneys rats with streptozotocin-induced diabetes (40 mg kg−1, iv). experimental groups (n=8) were control fed PR (CPR), WR, diabetic PR, WR. After 30 days treatment, all animals anesthetized exsanguinated before removal kidneys, which used to determine thiobarbituric acid reactive substances (TBARS), lipid hydroperoxides, carbonyl protein, superoxide dismutase, catalase,...
Considerando-se que dietas ricas em gordura levam ao estresse oxidativo, causando lesoes nas celulas e o treinamento hipoxico intermitente (THI) aumenta as defesas antioxidantes endogenas diversas situacoes, objetivo deste estudo foi avaliar efeito do THI parâmetros de oxidativo figado ratos Wistar alimentados com dieta rica e/ou padrao. Ratos foram divididos grupos padrao ou gordura. Os submetidos a hipoxia (HI), 15 minutos HI (14-11% O2) intercalados cinco re-oxigenacao sessoes normoxia...
