Innovative drug infusion technology for laboratory animals.

5-HT Dose Response      

Davis et al. (Davis et al., 2010) previously established, using both the iPRECIO® micro infusion pump and radiotelemetry devices, that 5-HT administration produced repeated falls in blood pressure in the sham (normotensive) and deoxycorticosterone acetate (DOCA)-salt (hypertensive) rat when the pump was turned on. When the pump was turned off (0.2μl/hour), blood pressure returned to normal. This study demonstrated that an equivalent effect was possible at a much lower dose than was previously studied (25 µg/serotonin hydrochloride /kg/min) in the sham and DOCA-salt rat.
