The average plasma Lp-PLA@ concentration -LSB- Lp-PLA@ ( V/V ) : @ ng/mL , Lp-PLA@ ( V/F ) : @ ng/mL , Lp-PLA@ ( F/F ) : @ ng/mL -RSB- and activity -LSB- Lp-PLA@ ( V/V ) : @ nmol/min/mL , LpPLA@ ( V/F ) : @ nmol/min/mL , Lp-PLA@ ( F/F ) : @ nmol/min/mL -RSB- were significantly different between each genotype , although the basic clinical characteristics were similar .
