Cell injury was assessed by morphological examination using phase-contrast microscopy and quantified by measuring the amount of lactate dehydrogenase (LDH) leakage; cell viability was measured by XTT reduction. Neuronal apoptosis was determined by flow cytometry, and electron microscopy was used to study morphological changes of neurons. Caspase-3,\u00a0-8, and\u00a0-9 activation and Bcl-2\/Bax protein expression were determined by Western blot analysis. We report that treatment with AVLE (5 and 50\u00a0\u00b5g\/mL) effectively reduced neuronal cell death and relieved cell injury induced by OGD. Moreover, AVLE decreased the percentage of apoptotic neurons, relieved neuronal morphological damage, suppressed overexpression of active caspase-3 and\u00a0-8 and Bax, and inhibited the reduction of Bcl-2 expression. These findings indicate that AVLE protects against OGD-induced injury by inhibiting apoptosis in rat cortical neurons by down-regulating caspase-3 activation and modulating the Bcl-2\/Bax ratio. <\/jats:p>","DOI":"10.1139\/y10-069","type":"journal-article","created":{"date-parts":[[2010,10,4]],"date-time":"2010-10-04T10:57:35Z","timestamp":1286189855000},"page":"907-917","source":"Crossref","is-referenced-by-count":21,"title":["<i>Apocynum venetum<\/i> leaf extract protects rat cortical neurons from injury induced by oxygen and glucose deprivation in vitro"],"prefix":"10.1139","volume":"88","author":[{"given":"Jun","family":"Xiang","sequence":"first","affiliation":[{"name":"Laboratory of Neurology, Institute of Integrative Medicine, Zhongshan Hospital, Fudan University, 180 Fenglin Road, Shanghai 200032, P.R.
