Figure 2 The AA uptake into skeletal muscle with both dialysis solutions in the fasting state and during insulin stimulation (clamp). The uptake of all AAs was significantly higher during AA dialysis solution than glucose-based solution, during both fasting and insulin stimulation. In system A AAs, the uptake in the fasting condition was significantly higher when AA solution was used than during glucose-based solution, and there was a trend toward a higher uptake during insulin stimulation when AA solution was used. All AAs, sum of concentrations of all AAs; sysA, sum of concentrations of six AAs that typically use system A for their transport; G, treatment with glucose-based solution; AA, treatment with AA-based solution.

Figure 3 Plasma AA concentrations with both dialysis solutions in the fasting state and during insulin stimulation (clamp). The concentrations of both AA groups were significantly higher during AA dialysis solution than glucose-based solution, during both fasting and insulin stimulation. All AAs, sum of concentrations of all AAs; sysA, sum of concentrations of six AAs that typically use system A for their transport; G, treatment with glucose-based solution; AA, treatment with AA-based solution.
