Study on the effect of urinary kallidinogenase after thrombolytic treatment for acute cerebral infarction.

OBJECTIVE: To evaluate the safety and efficacy of urinary kallidinogenase for recombinant tissue-type plasminogen activator (rt-PA) intravenous thrombolytic treatment in patients with acute cerebral infarction. PATIENTS AND METHODS: All 200 patients with acute cerebral infarction were randomized 1:1 into an experimental group (100 cases) and a control group (100 cases). Patients in the control groupwere administrated rt-PA (0/9 mg/kg) while patients in the experimental group were given urinary kallidinogenase by intravenous drip (0.15 PNAU/d, for 7 days) after rt-PA intravenous thrombolytic treatment (0.9 mg/kg). The main evaluation index was NIHSS and BI. RESULTS: Compared to the control group, the NIHSS scores were significantly lower 7 and 90 days after thrombolytic therapy (t = 2.391, 2.714; p < 0.05). BI scores were obviously higher at 90 days after thrombolytic therapy in the experimental group (t = 2.675, p < 0.05). CONCLUSIONS: Urinary kallidinogenase may improve the treatment effect for rt-PA intravenous thrombolytic treatment in patients with acute cerebral infraction.
