Inflammatory activation plays a vital role in the pathophysiological mechanisms of stroke, exerting deleterious effects on the progression of tissue damage and may lead to the vascular damage in diabetes. The objectives of this study were to determine the effects of rosmarinic acid (RA) on a cultured neuronal cell line, SH-SY5Y in vitro and experimental(More)
This study was conducted to investigate the neuroprotective effects of 20(S)-ginsenoside Rg3 on focal cerebral ischemia in rats. Middle cerebral artery occlusion (MCAO) model in male Wistar-Kyoto (WKY) rats was employed. The behavioral tests were used to evaluate the damage to central nervous system. The infarct area of brain was assessed in the brain(More)
In this study, we sought to elucidate whether protocatechuic acid contributes to induce angiogenesis as well as its mechanisms. To this end, we examined the role of protocatechuic acid on human brain microvascular endothelial cell line (HBMEC) proliferation, invasion and tube formation in in vitro. For the study of mechanisms involved, the phosphoinositide(More)
Postoperative peritoneal adhesions are common, serious complications of general abdominal and gynecologic surgery that can lead to chronic abdominal pain, intestinal obstruction, and infertility. As yet, there are no ideal drugs that may be prescribed for patients to prevent adhesion formation effectively. In this study the effects of escin, a natural drug,(More)
Cardiomyocyte apoptosis plays a critical role in the progress of heart diseases. Asperosaponin VI (ASA VI), a triterpene saponin isolated from Dipsacus asper Wall, has shown cardioprotective effects in vivo. However, whether ASA VI has a protective effect against cardiomyocyte apoptosis is poorly understood. The present study was aimed to investigate the(More)
(2E)-2-{6-[(E)-2-carboxyvinyl]-2,3-dihydroxyphenyl}-3-(3,4-dihydroxyphenyl) propenoic acid, a novel compound designated SMND-309, is a new derivate of salvianolic acid B. The present study was designed to investigate the cardioprotective potential of SMND-309 and to elucidate the possible mechanisms on the basis of biochemical, histopathological and(More)
Astilbin, a flavonoid compound was isolated from the rhizome of Smilax china L. In this study, we investigated the anti-myocardial ischemia and reperfusion (I/R) injury effect of Astilbin on diabetic rats in vivo and elucidated the potential mechanism in vitro. The results showed that Astilbin significantly attenuated hypoxia-induced cell injury in a(More)
An abnormal high mobility group box 1 (HMGB1) activation and a decrease in receptor for advanced glycation end-product (RAGE) play a key role in the pathogenesis of pulmonary fibrosis. Protocatechuic aldehyde (PA) is a naturally occurring compound, which is extracted from the degradation of phenolic acids. However, whether PA has anti-fibrotic functions is(More)
Sophocarpine, a tetracyclic quinolizidine alkaloid, is one of the most abundant active ingredients in Sophora alopecuroides L. Our previous studies have showed that sophocarpine exerts anti-inflammatory activity in animal models. In the present study, anti-inflammatory mechanisms of sophocarpine were investigated in lipopolysaccharide (LPS)-induced(More)
Asperosaponin VI is a saponin of the medicinal herb Dipsacus asper (Xuduan), and no pharmacological activity has been reported yet. In this study, we investigated the anti-myocardial ischemia effects of Asperosaponin VI (ASA VI) both in vivo and in vitro. An animal model of myocardial ischemia(MI) injury was induced by coronary occlusion, pretreatment with(More)
