OBJECTIVE To confirmed reliability and feasibility of intranasal nerve growth factor (NGF) bypassing the blood-brain barrier and its potential neuroprotective effects on acute cerebral ischemia. METHODS (1) To assay NGF concentrations in different brain regions after middle cerebral artery occlusion (MCAO). Rats were randomly divided into intranasal(More)
OBJECTIVE the purpose of the present study was to examine the protective effect of Icariside II (IS) on cerebral microcirculatory disturbance and neuronal injury in hippocampal CA1 region induced by global cerebral I/R and the underlying mechanism. METHODS male Mongolian gerbils (50-70 g) were subjected to bilateral common carotid arteries occlusion for(More)
OBJECTIVE This study was designed to investigate the protective potential of AS-IV against ischemia and I/R-induced myocardial damage, with focusing on possible involvement of energy metabolism modulation in its action and the time phase in which it takes effect. METHODS SD rats were subjected to 30 minutes LADCA occlusion, followed by reperfusion. MBF,(More)
Cardiac ischemia-reperfusion (I/R) injury remains a challenge for clinicians, which initiates with energy metabolism disorder. The present study was designed to investigate the protective effect of notoginsenoside R1 (NR1) on I/R-induced cardiac injury and underlying mechanism. Male Sprague-Dawley rats were subjected to 30-min occlusion of the left coronary(More)
PTEN is a dual specificity phosphatase and is implicated in inflammation and apoptosis of cerebral ischemia and reperfusion (I/R) injury. Bisperoxovanadium (Bpv), a specific inhibitor of PTEN's phosphatase activity, has demonstrated powerful neuroprotective properties. We investigated the neuroprotective roles of Bpv in the rat model of middle cerebral(More)
Disruption of blood-brain barrier (BBB) and subsequent edema are major contributors to the pathogenesis of ischemic stroke, for which the current clinical therapy remains unsatisfied. Cerebralcare Granule® (CG) is a compound Chinese medicine widely used in China for treatment of cerebrovascular diseases. CG has been demonstrated efficacy in attenuating the(More)
Lipopolysaccharide (LPS) is one of the common pathogens that causes mesentery hyperpermeability- and intestinal edema-related diseases. This study evaluated whether ginsenoside Rb1 (Rb1), an ingredient of a Chinese medicine Panax ginseng, has beneficial effects on mesentery microvascular hyperpermeability induced by LPS and the underlying mechanisms. Male(More)
OBJECTIVE TSI is a new drug derived from Chinese medicine for treatment of ischemic stroke in China. The aim of this study was to verify the therapeutic effect of TSI in a rat model of MCAO, and further explore the mechanism for its effect. METHODS Male Sprague-Dawley rats were subjected to right MCAO for 60 minutes followed by reperfusion. TSI (1.67(More)
OBJECTIVE To investigate the effects and possible mechanisms of CA on acute HHcy-induced leukocyte rolling and adhesion in mouse cerebral venules. METHODS Male C57 BL/6J mice were injected with DL-Hcy (50 mg/kg) and CA (10 mg/kg). The effect of CA on HHcy-induced leukocyte rolling and adhesion in cerebral vessels was assessed using intravital microscopy.(More)
The restoration of blood flow following thrombolytic therapy causes ischemia and reperfusion (I/R) injury leading to blood-brain barrier (BBB) disruption and subsequent brain edema in patients of ischemic stroke. Levo-tetrahydropalmatine (l-THP) occurs in Corydalis genus and some other plants. However, whether l-THP exerts protective role on BBB disruption(More)
