Effect of temperature on DPI action on ¹²⁵I⁻ efflux from PCCl3 preloaded cells. The cells were loaded with ¹²⁵I⁻ at 37 °C for 45 min, then quickly rinsed with 2 × 1 ml KRH at 37 °C or 22 °C or 15 °C. One milliliter of KRH at 37 °C (□) or 22 °C (Δ) or 15 °C (○) was then added and efflux measured at those temperatures. The arrows bind the basal and DPI stimulated release curves at each temperature. Empty symbols: basal release. Filled symbols: DPI stimulated release.
