Male Sprague-Dawley rats and male ICR mice, species respectively susceptible and resistant to the haemorrhagic effect of butylated hydroxytoluene (BHT), were administered BHT quinone methide (2,6-di-tert-butyl-4-methylene-2,5-cyclohexadienone) orally; 24 or 48 h later the plasma concentrations of
Pyrroloquinoline quinone (PQQ) has invoked considerable interest because of its presence in foods, antioxidant properties, cofactor of dehydrogenase, and amine oxidase. Protective roles of PQQ in central nervous system diseases, such as experimental stroke and spinal cord injury models have been
Two Gram-stain-negative, facultatively anaerobic bacteria, designated ZY170218T and ZY180512, were isolated from lungs of dead sheep with hemorrhagic pneumonia in Yunnan Province, China and their taxonomic positions were studied by a polyphasic approach. The two isolates grew optimally at
The roots of Rubia cordifolia L. (RCL) have become an important medicine for abnormal uterine bleeding (AUB) and hemorrhage syndrome in Traditional Asian medicine. However, the underlying mechanism and the material basis of RCL for treating AUB has not been fully elucidated. In this study,
The present work explored the anti-platelet effect produced by the quinone fractions (17.8, 35.7 and 71.4 microg/ml) isolated from the heartwood of Auxemma oncocalyx Taub. Our results show that the quinone fraction (QF) is a reversible and concentration-dependent inhibitor of human platelet
Sulfaquinoxaline (N1-(2-quinoxalinyl)sulfanilamide) has been shown to be a potent (Ki = 1 microM) freely reversible inhibitor of the dithiothreitol-dependent reduction of both vitamin K epoxide and vitamin K quinone by rat liver microsomes in vitro. This observation provides an explanation for the
To evaluate the effect of baicalin on subarachnoid hemorrhage (SAH) in rats and explore the potential mechanisms.Sprague-Dawley rats underwent experimental SAH and received treatment with baicalin at 10 or 50 mg/kg after 2 and 12 h of SAH. Neurological To investigate the regulatory effects of simvastatin on the inflammation and oxidative stress in rats with cerebral hemorrhage through the nuclear factor E2-related factor 2-antioxidant response element (Nrf2-ARE) signaling pathway.A total of 120 healthy Rhynchophylline (Rhy) has been demonstrated protective effects on some neurological diseases. However, the roles of Rhy in the subarachnoid hemorrhage (SAH) are still to be cleared. In the present study, the effects of Rhy on attenuation of early brain injury (EBI) after SAH have been evaluated. The
Astaxanthin (ATX) has been proven to ameliorate early brain injury (EBI) after experimental subarachnoid hemorrhage (SAH) by modulating cerebral oxidative stress. This study was performed to assess the effect of ATX on the Nrf2-ARE pathway and to explore the underlying molecular mechanisms of
The in vivo chicken embryo model (CEM) demonstrated that gallic acid (GA) induced dysvascularization and hypoxia. Inflammatory edema, Zenker's necrosis, hemolysis, and liposis of cervical muscles were the common symptoms. Levels of the gene hif-1α, HIF-1α, TNF-α, IL-6, and NFκB in cervical muscles
Aziridinylbenzoquinone (AZQ: NSC-182986), is a quinone derivative which has been shown to have activity in implanted murine tumor systems. Toxicity in small and large animals included hypothermia, diarrhea, anorexia, emesis, weight loss, and gastrointestinal bleeding. In addition, there was
OBJECTIVE
A growing body of evidence indicates that the nuclear factor erythroid 2-related factor 2-antioxidant response element (Nrf2-ARE) pathway plays a protective role in many physiological stress processes such as inflammatory damage, oxidative stress, and the accumulation of toxic metabolites,
