OBJECTIVE To investigate the protective effect of neuroprotection against transient focal cerebral ischemia of the extract from Tianma (Rhizoma Gastrodiae) and the possible mechanisms underlying the action. METHODS Cerebral ischemia-reperfusion injury was induced through middle cerebral artery

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.

BACKGROUND Previous studies have shown that proanthocyanidins have cardioprotective effects which are mediated via the release of nitric oxide (NO) ultimately resulting in increasing the antioxidant activity. We have investigated to show whether 1) the total extract and ethyl acetate fraction (Et)

BACKGROUND Uncaria sinensis (US) has been used in traditional Korean medicine to treat vascular disease and to relieve various neurological symptoms. OBJECTIVE Scientific evidence related to the effectiveness or action mechanism of US on cerebrovascular disease has not been examined experimentally.

Platelets are an important component of the initial response to vascular endothelial injury; however, platelet dysfunction induces the acute clinical symptoms of thrombotic disorders, which trigger severe cardiovascular diseases such as myocardial infarction, ischemia, and stroke. In this study, we

Polygonum multiflorum is a traditional Korean medicine that has been utilized widely in East Asian countries as a longevity agent. Clinical studies have demonstrated that Polygonum multiflorum improves hypercholesterolemia, coronary heart disease, neurosis and other diseases commonly associated with

Objective To study the protective effect of agrimony extracts from different extracting methods on cerebral ischemia-reperfusion injury in rats, in order to optimize the extraction scheme of agrimony. Methods Male rats were randomly assigned into seven groups: 1. Sham-operated group, 2. Untreated

Paeonia emodi Wall. ex Royle is an important member of family Paeoniaceae and folklorically used for constipation, hysteria, respiratory diseases, epilepsy and cardiac diseases like hypertension, palpitations, congestive heart failure and atherosclerosis. In the present study, ethyl acetate fraction

A simple high-performance liquid chromatographic procedure for quantifying lidocaine and nine of its metabolites in human plasma and urine is described. This method involves aqueous acetylation of the metabolites with acetic anhydride under mild basic conditions (pH approximately 8.5). Lidocaine and

Humans are experiencing serious health issues like myocardial infarction and diabetes. Thrombosis is the reason of myocardial infarction that may cause death. Bioactive compounds or enzymes can be used to dissolve the clot. Whereas diabetes is a disorder of metabolism in which the level of glucose

The purpose of the present study was to develop a new procedure for determining the oxidative modification of plasma fibrinogen. The procedure was developed to use blood plasma from 96 males aged 35-60 years who had cardiovascular diseases: 49 patients with coronary heart disease (CHD), including 16

OBJECTIVE The role of guggulipid was evaluated in high fat diet and middle cerebral artery occlusion (MCAO) induced ischemic cerebral dysfunctions in rats of either sex. METHODS Ethyl acetate extract of guggul known as guggulipid was prepared and administered to rats. Animals were divided into 9

As practice in folk medicine, Graptopetalum paraguayense E. Walther possesses several biological/pharmacological activities including hepatoprotective, anti-oxidant, and anti-inflammatory. We investigated the neuroprotective potential of Graptopetalum paraguayense E. Walther leaf extracts on

Ixeris sonchifolia Hance is an herb distributed in northeastern part of China and has been used by natives to invigorate circulation. In the present study, bioactivity-guided fractionation of I. sonchifolia Hance extract was performed with the aim to isolate and identify the compounds underlying the

BACKGROUND Shexiang Baoxin Pill (SBP) is a well-known composite formula of traditional Chinese medicine (TCM), widely used to treat cardiovascular diseases such as angina pectoris and myocardial infarction. Bufadienolides are major active compounds of Venenum Bufonis, which is one of the seven
