ABSTRACT
BACKGROUND: Neurological injury after cerebral air embolism may be due to thromboinflammatory responses at sites of air-injured endothelium. Because heparin inhibits multiple thromboinflammatory processes. we hypothesized that heparin would decrease neurological impairment after cerebral air embolism. METHODS: Anesthetized rabbits received either heparin (n=14) or saline (n=13), 5 minutes before air injection (150 microliter/kg). Heparin was given as a 200 IU/kg bolus and followed by a constant infusion of 75 IU/kg/h for 2 hours. Equal volumes of salines were given to saline group. Two hours later, anesthesia was discontinued. Rabbits were neurologically evaluated 24 hours after air embolism. RESULTS: Heparin group had significantly less neurological impairment at 24 hours (34 14) than saline controls (52 8) (p=0.0013). CONCLUSIONS: When given prophylactically, heparin decreases neurological impairment caused by severe cerebral arterial air embolism.

Objective To observe the effect of sublingual Nifedipine on brain function in emergency cases with hypertension.Methods The changes of blood pressure, electroencephalogram (EEG) and brain electrical activity mapping (BEAM) in 56 patients with emergency hypertension before and after sublingual Nifedipine were analyzed.Results Within 2 hours after sublingual medicine, EEG results improved in 3 cases and did not change in 27. More severe abnormal EEG changes were seen in 26 cases, ? and ? band power rose evidently in these patients (all P
ABSTRACT
This article is a summary of the revision and application of Halstead—Reitan neuropsychological testbattery for Children in China.With the same features and principles remained in the revised edition,the battery were ad-ministered to children aged 9 to 14 and the age norms of Chinese children were established.The results of this researchindicate that the revised edition is of good reliability and validity,and that it is useful in diagnosing brain damage,plan-ning rehabilitation,and directing children's learning.
