BACKGROUND The pathogenic accumulation of amyloid β peptide (Aβ), a natural occurring peptide processed from beta-amyloid precursor protein (APP), is considered to play a key role in the development of Alzheimer's disease (AD). Ginsenoside Rg1, an active component in ginseng, has been identified as a phytoestrogen and also found to be neuroprotective.(More)
The present study was undertaken to evaluate whether estrogen deprivation might lead to mitochondrial alteration of hippocampal neurons of ovariectomized (OVX) rats, and to evaluate the protective effect of estrogen and phytoestrogen on the mitochondrial alteration. First, OVX rats were used to mimic the pathologic changes of neurodegeneration of(More)
BACKGROUND/AIM Emerging evidence suggests that microRNA (miRNA) mediated gene regulation influences the maintenance of metabolic homeostasis, particularly the states of obesity and insulin resistance, thereby providing a potential link between miRNAs and nonalcoholic fatty liver disease (NAFLD). METHODS Sprague-Dawley rats fed a high-fat diet (HFD) were(More)
Standardized extract from the leaves of the Ginkgo biloba tree, labeled EGb761, is one of the most popular herbal supplements. Numerous preclinical studies have shown the neuroprotective effects of EGb761 and support the notion that it may be effective in the treatment and prevention of neurodegenerative disorders such as Alzheimer's disease (AD). Despite(More)
Bilobalide (BB), a sesquiterpene trilactone from Ginkgo biloba has been proposed to have protective effects on mitochondrial function. Using ovariectomized rats to mimic the post-menopausal pathophysiological changes in women, this study demonstrated that BB treatment could prevent estrogen withdrawal-induced decrease in mitochondrial adenosine triphosphate(More)
In the present study, ovariectomized Sprague-Dawley rats were used to mimic the pathological changes of post-menopausal females with genistein and estradiol benzoate (EB) as substitutes for endogenous estradiol. Measurements of hippocampal ATP content, mitochondrial ATP content and the rate of mitochondrial ATP synthesis in the hippocampus indicated that(More)
Bilobalide, a sesquiterpene trilactone constituent of Ginkgo biloba leaf extracts, has been proposed to exert protective and trophic effects on neurons. However, mechanisms underlying the protective effects of bilobalide remain unclear. Using human SH-SY5Y neuroblastoma cells and primary hippocampal neurons, this study investigated the neuroprotective(More)
A quantitative histological approach was employed to evaluate the effects of basic fibroblast growth factor (bFGF) in healing-impaired diabetic mice. The dorsal areas of female mutant diabetic mice, C57BL KsJ db/db (Jackson Lab.), were given two 6 mm-size full thickness wounds with a punch biopsy instrument. After application of bFGF, the wounds were left(More)
The stimulatory effect of recombinant human insulin-like growth factor-I (rhIGF-I) and recombinant human insulin-like growth-factor-binding protein-1 (rhIGFBP-1) on wound healing was assessed using diabetic db/db mice and normal rabbits. Full-thickness wounds of 6 mm diameter were prepared on the backs of diabetic C57BL/KsJ db/db mice and on the inner sides(More)
