OBJECTIVE: To investigate serum levels of endogenous oxidation agents, anti-oxidation agents and clinical significance in the patients with cerebral vascular disease (CVD). METHODS: Using biochemical methods, the levels of serum nitric oxide (NO), nitric oxide synthase (NOS), malondialdehyde (MDA) and anti-oxidants vitamin E (VitE), vitamin C (VitC), superoxide dismutase (SOD) in 49 patients with cerebral hemorrhage (CH), 65 patients with cerebral infarction(CI) and 35 patients with other nervous system diseases and 34 healthy controls were determined. RESULTS: In CH and CI groups, the levels of serum NO and MDA and the activity of serum NOS were significantly higher than that of the two other groups (P<0.05 or P<0.01). On the other hand, the patients with CH and CI had lower VitE, VitC levels and SOD activity than that of the two control groups (P<0.05 or P<0.01). CONCLUSION: These findings suggest NO and NOS plays an important role in pathogenesis of cerebral damage after CH and CI. Determination of the concentrations of NO, VitE, VitC, MDA level, and NOS and SOD activity in serum can also help judge the seriousness and the course of the disease.
