Figure 1From: Bacterial melanin crosses the blood–brain barrier in rat experimental modelGraph of influx of bacterial melanin into brain (A br /(Ĉp · t)) against exposure time ([∫Cp(T)dT]/cpt). The solid line represents the linear fit of all the data points. The slope of the line is equivalent to KI (rate of unidirectional solute flux from plasma across the BBB) and the ordinate intercept is equivalent to VI (functional distribution volume of the substance that exchanges with plasma).Back to article page
