BACKGROUND: Various etiological mechanisms are involved in cerebral infarction. Both free radicals and lipid peroxidation participate in the atherosclerosis and damage of neural cells after cerebral ischemia. Compound danshen(Radix Salviae Miltiorrhizae) is a common prescribed Chinese herb, acting on activating blood circulation and removing stasis for cerebral infarction and coronary heart disease, but its mechanism has been unknown in many aspects.OBJECTIVE: To observe the effect of compound danshen on neural function defect and free radicals in patients with cerebral infarction so as to probe into its possible mechanisms.DESIGN: A randomized controlled trial.SETTING: Neurological Internal Department of a hospital affiliated to one university.PARTICIPANTS: Totally 538 inpatients were collected in Neurological Internal Department of First Hospital affiliated to Jinzhou Medical College from February to December 2002, their diagnosis compiled with "Diagnostic Keys on Every Type Cerebral Vascular Disorders" adopted on the 4th National Acadenic Meeting on Cerebral Vascular Disorders, and determined by cerebral CT scan. All of those were the first attack of atherosclerosis cerebral infarction in 72 hours. The patients with cardiac infarction, heart failure, auricular fibrillation, insufficiency of liver and kidney function,hemorrhage of digestive tract, vascular dementia and bulbar paralysis and the patients who could not be well cooperated were not included. A total of 68 patients compiled with the standards, of which, 38 patients were male and 30 patients female, aged varied from 52 to 78 years, at the average of (64. 62 ±5.80) years. The patients selected were randomized into study group and the control by lot-drawing nethod according to the hospitalized sequence and volunteer principle of the control.METHODS: The basic treatment was same in two groups. In study group,compound danshen injection was added together with physiological saline 250 mL for intra-venous drip, once daily, continuous 14 days made one course. In the control, thrombosis removing injection 15 mL was added together with physiological saline 250 mL for intra-venous drip, once daily,continuous 14 days made one course.Level of serum lipoperoxide(LPO) and activity of superoxide dismutase (SOD).RESULTS: Statistical differences presented in declined scores of severity of neural function defect after treatment in two groups compared with their own controls(in study group: 28.62 ±6.76 vs 13.84 ± 8.16; in the control:28.58±7.05 vs 21.52±8.24, t=8.134, t=3.796 respectively, P< 0. 001 ). The score in study group was declined more obviously compared with the control after treatment, indicating very significant difference ( t = 3. 861, P < 0. 001 ). The effective rate of compound danshen injection was 88.24% in treatment of cerebral infarction, which significantly superior to that in the control(67.65% ) (x2 =4.19, P < 0.05). Compound danshen remarkably reduced serum LPO level[ (8.69 ± 1.28) nmol/L vs (5.86 ± 1.42) nmol/L, t =8. 628, P < 0. 001 ] and statistical differences presented compared with the result in the control after treatment[(5.86±1.42) nmol/L vs(8.56±0.95) nmol/L, t=9.125, P <0.001] . Simultaneously, SOD activity in serum was significantly increased, [ (26. 25±4. 64) mkat/g vs(30. 01 ± 3.87) mkat/g, t = 3. 629, P < 0. 001] indicating statistical differences compared with the result in the control after treatment[ (30. 01 ±3.87) mkat/g vs(26.33 ±4. 14) mkat/g, t =3. 778,P < 0.001].CONCLUSION: Compound danshen improves significantly neural function defect in patients with cerebral infarction, with definite therapeutic effects on the treatment. It can reduce serum LPO content and increase serum SOD activity in patients with cerebral infarction. It is predicted that removing free radicals and anti-lipid peroxidation damage is probably one of the important mechanisms of it, which provides a further theoretic evidence for the treatment of cerebral infarction clinically.
