Salivary Antioxidant Barrier, Redox Status, and Oxidative Damage to Proteins and Lipids in Healthy Children, Adults, and the Elderly

Table 2

Differences between nonstimulated and stimulated saliva of healthy children (aged 2-14), adults (aged 25-45), and elderly people (aged 65-85).

	2-14		25-45		65-85
	NWS	SWS	NWS	SWS	NWS	SWS
CAT (mU/mg protein)
Px (nmol/min/mg protein)
SOD (mU/mg protein)
GSH (μg/mg protein)
UA (μg/mg protein)
TAC (μmol/mg protein)
TOS (nmol/mg protein)
AGE (AFU/mg protein)
AOPP (nmol/mg protein)
MDA (μmol/mg protein)

AGE—advanced glycation end products; AOPP—advanced oxidation protein products; CAT—catalase; GPx—glutathione peroxidase; GSH—reduced glutathione; MDA—malondialdehyde; NWS—nonstimulated whole saliva; Px—salivary peroxidase; SOD—superoxide dismutase-1; SWS—stimulated whole saliva; TAC—total antioxidant capacity; TOS—advanced oxidation protein products; UA—uric acid. vs. NWS.
