Abstract

Erigeron annuus (L.) PERS. (EALP) and Clematis mandshurica RUPR. (CMR) have been used in traditional remedies due to their medicinal effects. Recently, we reported that pretreatment with 200 mg/kg of YES‑10® (a combination of extracts from leaves of EALP and CMR) displayed neuroprotective effects against brain ischemia and reperfusion injury. The present study analyzed the major ingredients of YES‑10® and investigated whether neuroprotection from YES‑10® was dependent upon antioxidant effects in the cornu ammonis 1 (CA1) field in the gerbil hippocampus, after transient forebrain ischemia for 5 min. YES‑10® was demonstrated to predominantly contain scutellarin and chlorogenic acid. Pretreatment with YES‑10® significantly increased protein levels and the immunoreactivity of copper/zinc‑superoxide dismutase (SOD1) and manganese‑superoxide dismutase (SOD2) was in the pyramidal neurons of the hippocampal CA1 field when these were examined prior to transient ischemia induction. The increased SODs in CA1 pyramidal neurons following YES‑10® treatment were maintained after ischemic injury. In this case, the CA1 pyramidal neurons were protected from ischemia‑reperfusion injury. Oxidative stress was significantly attenuated in the CA1 pyramidal neurons, and this was determined by 4‑hydroxy‑2‑nonenal immunohistochemistry and dihydroethidium histofluorescence staining. Taken together, the results indicated that YES‑10® significantly attenuated transient ischemia‑induced oxidative stress and may be utilized for developing a protective agent against ischemic insults.
