Baroreflex function in conscious rats
Our hypothesis is that iron accumulated in tissue, rather than in serum, may compromise cardiovascular control. Male Fischer 344 rats weighing 180 to 220 g were divided into 2 groups. In the serum iron overload group (SIO, N = 12), 20 mg elemental iron was injected ip daily for 7 days. In the tissue iron overload group (TIO, N = 19), a smaller amount of elemental iron was injected (10 mg, daily...
متن کاملCardiopulmonary baroreflex in NaCl-induced hypertension in borderline hypertensive rats.
Borderline hypertensive rats fed an 8% NaCl diet develop increased arterial pressure in association with increased cardiopulmonary baroreflex sensitivity compared with rats fed a 1% NaCl diet. We performed experiments to localize the site of sensitization within the cardiopulmonary baroreflex. To determine whether decreased cardiopulmonary baroreflex sensitivity, as seen in other models of NaCl...
متن کاملPostnatal intermittent hypoxia alters baroreflex function in adult rats.
Chronic perinatal intermittent hypoxia (IH) could have long-term cardiovascular effects by altering baroreflex function. To examine this hypothesis, we exposed rats (n = 6/group) for postnatal days 1-30 or prenatal embryonic days 5-21 to IH (8% ambient O2 for 90 s after 90 s of 21% of O2, 12 h/day) or to normoxia (control). Baroreflex sensitivity (BRS) and cardiac chronotropic responses were ex...
متن کاملEvaluation of baroreflex function in young spontaneously hypertensive rats.
BACKGROUND The literature describes contradictory data regarding the onset of the baroreflex reduction in spontaneously hypertensive rats. OBJECTIVE This investigation was undertaken to evaluate the baroreflex function in 13-week-old spontaneously hypertensive rats. METHODS Male Wistar Kyoto (n=15) and spontaneously hypertensive rats (n=15) aged 13 weeks were studied. Cannulas were inserted...
متن کاملVascular reactivity and baroreflex function during hyperthermia in conscious rats.
The hemodynamic responses to vasoconstrictor agents are blunted during heating in anesthetized rats. It is unknown whether reflex neural responses to these agents are also altered during hyperthermia. Therefore, the purpose of this study was to determine the effect of hyperthermia on the hemodynamic and baroreflex-mediated sympathetic neural responses to vasoactive agents in conscious, unrestra...
