Table 2. Epidermal metabolite levels 72 hours after surgery.

Groups	Glucose (mmol/gprot)	Lactate (mmol/gprot)	Lactate/Glucose Ratio
Control group▲ (Arterial perfusion group)	0.858 ± 0.028	1.130 ± 0.078	1.32 ± 0.09
Experimental group I▼ (inflow:outflow,1:1)	0.436 ± 0.025	1.710 ± 0.09	3.93 ± 0.31
Experimental group II♥ (inflow:outflow,1:2)	0.611 ± 0.016	1.539 ± 0.104	2.52 ± 0.18
Experimental group III (inflow:outflow,1:3)	0.623 ± 0.019	1.486 ± 0.119	2.38 ± 0.13

^▲Values of the control group were significantly different from the three experimental groups (all p < 0.01); ^▼ those of the experimental group I were also significantly different from the other three groups (all p < 0.01); ^♥ no differences were noted between the experimental group II and III (Glucose: p = 0.377; Lactate: p = 0.371).
