Abstract:
Objective To explore the therapeutic effect of low level laser irradiation (LLLI) on cerebral infraction combined with hypertension.Methods Two groups were divided, conventional treatment group and laser irradiation combined with conventional treatment group.LLLI (650 nm, 20 mW, 20 min, twice a day, two weeks therapy) was used by extravascular way in addition to conventional treatment, while control group employed conventional treatment only.Whole blood viscosity, plasma blood pressure, lipid and neurological function were assessed by comparing the index of the two groups.Results Whole blood viscosity, plasma viscosity, whole blood high shear reductive viscosity, hematokit (HTC), erythrocyte deformation index, erythrocyte rigidity index, fibrinogen and blood lipid level of both groups decreased and the decrease of the testing group was more significant than that of control group (P＜0.05 or P＜0.01).Neurological deficit score an blood pressure of both groups showed significant decrease (P＜0.05), and the decrease in blood pressure of testing group was significant than that of the control group (P＜0.05 or P＜0.01).Conclusions 650 nm extravascular LLLI may be effective in treatment of cerebral infraction combined with hypertension, and has a good application prospect.
