The effect of dopamine (10(-6) M) on PO4 reabsorption was studied in isolated and perfused proximal convoluted and straight tubules of the rabbit. In convoluted tubules, fluid reabsorption (JV), PO4 lumen-to-bath (JPO4lb), and net (net JPO4) fluxes did not change during dopamine exposure. In S3 segments bathed in rabbit serum, JV diminished significantly during dopamine exposure. JPO4 decreased by 20% (p less than 0.005) and net JPO4 decreased by 27% (p less than 0.02). The effect of dopamine was reversible upon removal of the drug.
在兔离体灌注的近端曲管和直管中研究了多巴胺(10⁻⁶ M)对磷酸根(PO₄)重吸收的影响。在曲管中,多巴胺作用期间液体重吸收(JV)、PO₄从管腔到浴液的通量(JPO₄lb)和净通量(净JPO₄)均未改变。在浸浴于兔血清中的S3节段,多巴胺作用期间JV显著降低。JPO₄降低了20%(p<0.005),净JPO₄降低了27%(p<0.02)。去除药物后,多巴胺的作用是可逆的。
