AIM To investigate the effect of chronic H1-antihistamine treatment on seizure susceptibility after drug withdrawal in nonepileptic rats and to further study its relation to glutamine synthetase (GS), which is the key enzyme for glutamate metabolism and gamma aminobutyric acid (GABA) synthesis. METHODS After drug withdrawal from a 2-week treatment with(More)
AIM Lactates accumulate in ischemic brains. G protein-coupled receptor 81 (GPR81) is an endogenous receptor for lactate. We aimed to explore whether lactate is involved in ischemic injury via activating GPR81. METHODS N2A cells were transfected with GFP-GPR81 plasmids 24 h previously, and then treated with GPR81 antagonist 3-hydroxy-butyrate (3-OBA) alone(More)
Febrile seizures (FS) are generally defined as seizures taking place during fever. Long-term prognosis, including development of epilepsy and malformation of cognitive function, has been demonstrated after infantile FS. However, the mechanism that triggers seizures in hyperthermic environment is still unclear. We here found that the body temperature of rat(More)
Long-term metformin treatment reduces the risk of stroke. However, the effective administration pattern and indications of metformin on acute cerebral ischemia are unclear. To investigate the neuroprotective treatment duration and dosage of metformin on focal ischemia mice and the association of neuroprotection with 5′-adenosine monophosphate-activated(More)
AIM This study investigated whether histamine could play a protective role in pathophysiological response of spinal cord injury (SCI) and regulate the glial scar formation. METHODS Functional assessment and histological analyses were performed to investigate the effect of histamine after SCI. Histidine decarboxylase knockout (HDC(-/-)) mice were used to(More)
The formation of glial scar impedes the neurogenesis and neural functional recovery following cerebral ischemia. Histamine showed neuroprotection at early stage after cerebral ischemia, however, its long-term effect, especially on glial scar formation, hasn't been characterized. With various administration regimens constructed for histidine, a precursor of(More)
AIM Cerebral ischemic postconditioning has emerged recently as a kind of endogenous strategy for neuroprotection. We set out to test whether hypoxia or glucose deprivation (GD) would substitute for ischemia in postconditioning. METHODS Adult male C57BL/6J mice were treated with postconditioning evoked by ischemia (bilateral common carotid arteries(More)
