Coronary sinus outflow dilution curves for [14C]inosine ([14C]Ino), [3H]arabinofuranosyl hypoxanthine ([3H]AraH), and 131I-albumin; model solutions are continuous lines. Extractions and recoveries are listed in Tables 1 and 2. Parameters for model fits are in Table 4; each estimate is given with its individual standard deviation. Top: data from an isolated, perfused rabbit heart. Fp = 3.89 ml · g−1 · min−1. Bottom: data from an isolated, perfused guinea pig heart. Fp = 3.57 ml · g−1 · min−1. Note that Ino curve is lower than AraH curve, indicating higher values of PSecl in guinea pig compared with rabbit.
