FIG. 2.

Left panel: subcutaneous sampling; right panel: visceral sampling. Plasma measurements during deuterated cortisol infusion. Data are means ± SE for n = 6 (subcutaneous measurements) and n = 4 (visceral measurements) during deuterated cortisol infusion, with plasma samples from arterialized (▪), portal or subcutaneous (⋄), and hepatic (▴) cannulae. Plasma cortisol concentrations (A), plasma d4-cortisol enrichment (C), and d4-cortisol–to–d3-cortisol ratio (E) for subcutaneous study. Plasma cortisol concentrations (B), plasma d4-cortisol enrichment (D), d4-cortisol–to–d3-cortisol ratio (F) for visceral study. Statistical comparison of mean values in steady state (180–210 min) is shown in Table 2.
