AIM To investigate the effects of phenytoin (DPH) on morphological and structural changes of pyramidal neurons in hippocampal CA3 of rats induced by chronic stress. METHODS Using Nissl staining, Golgi staining, and electron microscope, the morphology and structure of pyramidal neurons in hippocampal CA3 of rats were observed. RESULTS Chronic stress(More)
We have previously shown that N-n-butyl haloperidol iodide (F(2)), a newly synthesized compound, reduces ischemia/reperfusion (I/R) injury by preventing intracellular Ca(2+) overload through inhibiting L-type calcium channels and outward current of Na(+)/Ca(2+) exchanger. This study was to investigate the effects of F(2) on activity and protein expression(More)
A simple and reliable method was developed for the determination of serum copper and zinc in different chemical forms by graphite furnace atomic absorption spectrometry (GFAAS) with ethanol-EDTA precipitation. The serum and ethanol were mixed with volume ratio 1 : 2. The mixture was incubated at 70 degrees C and ultra-centrifuged to precipitate proteins.(More)
N-n-Butyl haloperidol iodide (F2), a novel compound derived from haloperidol, protects against the damaging effects of ischemia/reperfusion (I/R) injury in vitro and in vivo. We tested whether the myocardial protection of F2 on cardiomyocyte hypoxia/reoxygenation (H/R) injury is mediated by modulating protein kinase C (PKC) activity in primary cultured(More)
We have previously shown that N-n-butyl haloperidol iodide (F2) derived from haloperidol reduces ischemia/reperfusion-induced myocardial injury by blocking intracellular Ca2+ overload. This study tested the hypothesis that cardio-protection with F2 is associated with an attenuation in the expression of early growth response gene 1 (Egr-1). In an in vivo rat(More)
OBJECTIVE To observe the histopathological changes of a novel small-caliber vascular graft after implantation in canine theca interna under scanning electron microscope. METHOD A 3 cm segment of the vascular graft (diameter of 4 mm) was implanted in an end-to-end fashion to bridge the severed carotid artery in 19 healthy dogs. Color Doppler sonography was(More)
A method was developed for the determination of trace free copper and zinc in serum sample by GFAAS after two-step precipitation. The serum and ethanol were mixed with volume ratio of 1 : 2. The mixture was subsequently denatured at 70 degrees C and centrifuged to precipitate proteins. The determination, limit of copper (3sigma) was 1.2 microg x L(-1) and(More)
OBJECTIVES To study the effect of testicular local heating on spermatogenic cell apoptosis in rat. METHODS Seventy male SD rats were divided into heat treatment group (43 degrees C) and control group (22 degrees C). Each group was further divided into seven sub-groups respectively according to the time of 12 hours and 1 days, 3 days, 6 days, 10 days, 50(More)
Mast cells play a central role in the intestinal immune response. To investigate the relationship between degranulation, cell polarization and the reorganization of actin cytoskeleton of mast cells, we used fluorescence or gold labeling methods to identify different mast cell subtypes in human colon. The reorganization of filamentous actin was visualized(More)
