OBJECTIVE
Thioredoxin-1 has various biologic activities, including the control of redox balance and the inhibition of apoptosis. The current study was designed to examine the effects of panaxatriol saponins (PTS) extracted from Panax notoginseng on thioredoxin-1 expression and
OBJECTIVE
To study the protective effects and its mechanism of Panaxatriol Saponins isolated from Panax notoginseng (PTS) on focal cerebral ischemia in rat brain.
METHODS
The influences of PTS on cerebral water content and three specific proteins (VEGF, HSP70 and transferrin) related with cerebral
OBJECTIVE
Panaxatriol saponins (PTS), the main constituents extracted from Panax notoginseng, a Chinese herbal medicine, has been shown to be an effective agent on various diseases. Our previous study has demonstrated that PTS is an inducer of thioredoxin-1 (Trx-1) and has a possible potential as a
Total saponins of Panax notoginseng (PNS) have been shown to ameliorate renal interstitial fibrosis. Ginsenoside Rg1, a panaxatriol saponin, is one of the major active molecules from PNS. The present study was undertaken to investigate the effect of ginsenoside Rg1 on renal fibrosis in rats with
PTS, one of the major effective components of Panax notoginseng was found to exert remarked antiarrhythmic activities on coronary artery ligation induced ischemic and reperfused arrhythmias in rats. PTS also reduced the size of myocardial infarct. For i.v. CaCl2-Ach induced atrial fibrillation
The electrophysiological effects of PTS in sheep cardiac Purkinje fibers were studied. PTS was shown to increase the duration of action potential (APD30, APD50 and APD90) at the concentrations of 2.5 micrograms/ml and 5.0 micrograms/ml. However, the amplitude of action potential (APA) remained
Panaxatriol saponins (PTS), the main components extracted from Panax notoginseng, have been shown to be efficacious in the prevention and treatment of cerebrovascular diseases in China. NF-E2-related factor 2 (Nrf2), a transcription factor regulating antioxidant and cytoprotective responses to
OBJECTIVE
Acetaminophen (APAP) is widely used as an antipyretic agent which is safe at therapeutic doses. However, overdose of APAP induces fatal and non-fatal hepatic necroses. The chemical reactive metabolites of APAP initiate toxicity and inflammatory response within the liver and lead to acute
Hormesis is an adaptive response of living organisms to a moderate stress. However, its biomedical implication and molecular mechanisms remain to be intensively investigated. Panaxatriol saponins (PTS) is the major bioactive components extracted from Panax notoginseng, a widely used herbal medicine
BACKGROUND
Panaxatriol saponins (PTS), an extract from the traditional Chinese herb Panax notoginseng, which has been used to treat ischemic stroke for many years in China. However, the mechanism underlying the effects of PTS remains unclear. This study aimed to determine whether PTS can protect
BACKGROUND
Increased platelet aggregation is implicated in the pathogenesis of ischemic stroke and anti-platelet strategy may contribute to its therapy. Panaxatriol saponin (PTS), the main components extracted from Panax notoginseng, has been shown to be efficacious in the prevention and treatment
