ABSTRACT
Objective To investigate correlations between peripheral benzodiazepine receptors(PBRs) in mitochondria and synaptosomes in the brain and platelet membrane of rats during aging and to explore the significance of the relationships.Methods Sprague-Dawley rats of both sexes were divided into 3-,12-and(24-month) groups.All animals were sacrificed by decapitation and the brains were immediately removed.Mitochondrial components from dissected cerebral cortex and synaptosomal fractions from dissected hippocampus were isolated by gradient centrifugation.The membrane of platelets from venous blood was prepared by the method of hypotonic haemolysis.The specific binding assay of the radioactive PBRs antagonist PK11195 to membrane was performed.(Results A significant) difference about PK11195 binding activity of mitochondria was observed among three groups(F=194.6,P
ABSTRACT
Objective To explore the change of peripheral benzodiazepine receptors (PBR) expression in the telencephalon of mice with schistosomiasis. Methods The changes of PBR mRNA in the telencephalon of schistosomiasis mice were observed by the real-time FQ-PCR method. The results were judged with circle number of times (C_T) when the level of amplification exponent achieved detecting liminal value. Results Comparing the experiment group (n=10) with the healthy control (n=10) at the 8th、12th、20th week, the changes of C_T were significant(P
