Low dose gamma-butyrolactone (GBL) therapy alters the natural history of experimental forebrain ischemia in the awake rat. After 30 minutes of four-vessel ischemia, repeated hydrogen cerebral blood flow determinations in awake rats over 72 hours revealed that low dose GBL therapy prevented the
A number of drugs and psychological stressors induce brain hyperthermia and increase extracellular dopamine in the caudate-putamen. The present study tested whether caudate-putamen hyperthermia produced by such stimuli is dependent on dopaminergic transmission. Rats were infused with
Leaves or infusions of feverfew, Tanacetum parthenium, have long been used as a folk remedy for fever, arthritis and migraine, and derived products are widely available in U.K. health food shops. Previous reports have suggested interactions with arachidonate metabolism. Crude chloroform extracts of
The pharmacological effects of a new anti-inflammatory compound, alpha-(3,5-di-tert-butyl-4-hydroxybenzylidene)-gamma-butyrolactone (KME-4), and its inhibitory effects on arachidonate prostaglandin synthetase and 5-lipoxygenase activities were examined. KME-4 showed anti-inflammatory activity. It
