OBJECTIVE
To observe the effect of Oxymatrine on left cardiac function and ventricular remodeling in rabbits after acute myocardial infarction.
METHODS
Ligation of the left anterior descending artery was adopted to establish acute myocardial infarction model, forty eight rabbits were randomized into

OBJECTIVE
To study the protective effect of oxymatrine (OMT) on myocardial fibrosis induced by acute myocardial infarction in rats and its effect on TGF-beta-Smads signal pathway.
METHODS
Arteria coronaria ligation-induced acute myocardial infarction model was established in rats. The survived rats

OBJECTIVE
To study the effects of oxymatrine (Oxy) on arrhythmia in dogs with myocardial infarction.
METHODS
Partly ligating the left anterior descending coronary artery in the open-chest dogs produced myocardial infarction of left anterior ventricular wall. After 5-8 d, the diastolic excitability

Oxymatrine (1), a component extracted from a traditional Chinese herb Sophora japonica (Sophora flavescens Ait.), has been demonstrated to have a variety of pharmacological actions. Abundant experimental evidence indicates that 1 may exert a protective effect on the cardiovascular system. This study
Inhibitory effects of oxymatrine on TGF‑β1‑induced proliferation and abnormal differentiation in rat cardiac fibroblasts via the p38MAPK and ERK1/2 signaling pathways.

Interstitial fibrosis serves a causal role in the development of heart failure following acute and chronic myocardial infarction, and anti‑fibrotic therapy represents a promising strategy to mitigate this pathological process. Oxymatrine (OMT) exerts a number of pharmacological effects on the
The neuroprotection of oxymatrine in cerebral ischemia/reperfusion is related to nuclear factor erythroid 2-related factor 2 (nrf2)-mediated antioxidant response: role of nrf2 and hemeoxygenase-1 expression.

Cerebral ischemia-reperfusion (CI/R) injury remains a major medical problem due to the lack of effective therapies. Previous studies have shown that increasing the activity of the transcription factor nuclear factor erythroid 2-related factor 2 (Nrf2) and gene targets in cell culture and stroke

BACKGROUND
Oxymatrine is proven to protect ischemic and reperfusion injury in liver, intestine and heart, this effect is via anti-inflammation and anti-apoptosis. Whether this protective effect applies to ischemic injury in brain, we therefore investigate the potential neuroprotective role of
Oxymatrine downregulates TLR4, TLR2, MyD88, and NF-kappaB and protects rat brains against focal ischemia.

Inflammatory damage plays an important role in cerebral ischemic pathogenesis and may represent a target for treatment. Toll-like receptor-4 (TLR4), toll-like receptor-2 (TLR2), myeloid differentiation factor 88 (MyD88), and nuclear factor kappa-B (NF-kappaB) have been linked to inflammatory

OBJECTIVE
Oxymatrine, extracted from a traditional Chinese herb, Sophora flavescens Ait, has shown a variety of pharmacological actions. Recently, we have proved that oxymatrine protected brain from ischemic damage. However, little is known about the exact mechanisms of this effect. This study is to

Matrine (Mat) and oxymatrine are two major alkaloids of the Chinese herb Sophora flavescens Ait. (Leguminosae). Previous study has demonstrated that Mat reduces brain edema induced by focal cerebral ischemia. More recently, oxymatrine has been reported to produce neuroprotective effects against

Large amounts of brain nitric oxide are produced over several hours after a stroke. This probably causes DNA strand nicks, nitration of cytosolic components of neurons, and ultimately neuronal death. Oxymatrine and matrine are two major alkaloids of the Chinese herb Sophora flavescens Ait.
