ABSTRACT
Objective To investigate correlation between seizures and uric acid level in the hippocampus in a mouse model with acute limbic seizures by pharmacological and genetic method. Methods Normal male C57BL/6 and mutant mice were used in this study,including urate oxidase overexpression (UOx-OE) and urate oxidase knock-out (UOx-KO) ;These mice were divided into the following groups,including the control,KA, All ,OE ,KO group respectively;during the experiment ,behaviors ,latency and duration time were recorded;dialysates were collected by microdialysis technique and uric acid level was detected by FPLC;Uric acid in the hippocampus,seizures status,latency and duration were compared. Results Twenty-four mice in total were enrolled and only 1 death occurred until the end of the study. Seizures state appeared after KA treatment. Compared to the KA group,uric acid and generalized seizures declined by the treatment of KA and All (P 0.05). Conclusions Uric acid level in the hippocampus of mice may have effects on seizures ,in which it suggests that uric acid and its relevant signal pathway could be a potential therapy target in seizures clinically.
ABSTRACT
@# ObjectiveTo investigate the characteristic and the function of the eye movements system of the patients with vertebral-basilar insufficiency (VBI).Methods83 patients with VBI and 57 healthy controls were tested with electronystagmogram instrument,include saccade test, Eye Tracking Test (ETT) and optokinetic test(OKN).Results and ConclusionDelay lower accuracy of saccade test, decreased gain of OKN, asymmetry of horizontal ETT were showed in the patients with VBI.
