Sympathetic responses to stress and rilmenidine in 2K1C rabbits: evidence of enhanced nonvascular effector mechanism.
We determined whether the sympathetic excitatory responses to environmental stressors and the sympathoinhibitory responses to rilmenidine are altered by renovascular hypertension. Rabbits were made hypertensive with a clip on the right renal artery, and a left renal nerve recording electrode was implanted. After 3 or 6 weeks, the animals were given air-jet stress and loud noise stress before an...
متن کاملEffects of hyperinsulinemia on sympathetic responses to mental stress.
In a recent study, we could not find evidence to support the hypothesis that insulin activates the sympathetic nervous system (SNS) during a hyperinsulinemic glucose clamp procedure. Mental stress tests (MST), however, may be used to detect differences in blood pressure and SNS activity that are not present during baseline or resting conditions. In this study, we aimed to investigate the effect...
متن کاملSympathetic neural responses to mental stress during acute simulated microgravity.
Neural and cardiovascular responses to mental stress and acute 6 degrees head-down tilt (HDT) were examined separately and combined. We hypothesized sympathoexcitation during mental stress, sympathoinhibition during HDT, and an additive neural interaction during combined mental stress and HDT. Muscle sympathetic nerve activity (MSNA), mean arterial pressure (MAP), and heart rate (HR) were recor...
متن کاملPhysio-biochemical and Enzymatic Responses of Sunflower to Drought Stress
Drought stress is a serious adverse factor that limits sunflower growth and productivity. The stress induces a range of physiological and biochemical responses in sunflower. So, evaluation of defense systems is important for producing resistant cultivars. In this study, physio-biochemical changes and antioxidant enzymes activitiesof six sunflower lines were evaluated under normal and irrigation...
متن کاملResponses of Almond Genotypes to Osmotic Stress Induced In Vitro
Drought is one of the major limitations to crop production worldwide. This study was conducted to evaluate the response of five almond genotypes and peach×almond hybrid GF to drought stress in vitro, and screening drought tolerance. Explants subjected to polyethylene glycol osmotic stress ( , , and . % WV) on the MS medium. Increasing PEG level in the medium significantly reduced fresh weight a...
