arachidonic acid/구역질

OBJECTIVE To evaluate the role of 2-arachidonoyl glycerol (2AG) in the regulation of nausea and vomiting using animal models of vomiting and of nausea-like behaviour (conditioned gaping). METHODS Vomiting was assessed in shrews (Suncus murinus), pretreated with JZL184, a selective monoacylglycerol

The effect ofcannabis can be explained on the basis of the function of the cannabinoid receptor system, which consists of CB receptors (CB1, CB2), endoligands to activate these receptors and an enzyme--fatty acid amidohydrolase--to metabolize the endoligands. The endoligands of the cannabinoid

The endogenous cannabinoid (CB) (endocannabinoid) signaling system is involved in a variety of (patho)physiological processes, primarily by virtue of natural, arachidonic acid-derived lipids (endocannabinoids) that activate G protein-coupled CB1 and CB2 receptors. A hyperactive endocannabinoid

The effects of 9 beta-methyl carbacyclin, a chemically stable analogue of epoprostenol (prostacyclin, PGI2) were studied, in comparison with epoprostenol, both in vitro and in vivo in man. In vitro 9 beta-methyl carbacyclin and epoprostenol inhibited platelet aggregation induced by ADP, collagen,

Perfluorooctyl bromide is an oxygen-carrying perfluorocarbon presently under development as an artificial blood substitute (Oxygent HT). Intravenous (i.v.) Oxygent HT elicits a mild side-effect profile in man characterized by early onset headache and nausea and delayed onset fever. Early onset

A 34 year old male bitten by an adult Atheris squamiger snake developed symptoms of nausea, vomiting, diarrhea which were followed by drowsiness and impaired breathing. Local hemorrhage, edema and pain at the bite-site occurred, but no systemic bleeding or hemorrhagic diathesis developed. All

The leukotrienes constitute a group of arachidonic acid-derived compounds with biologic activities suggesting important roles in inflammation and immediate hypersensitivity. Epidermis-type lipoxygenase-3 (ALOXE3), a distinct subclass within the multigene family of mammalian lipoxygenases, is a novel

Angioedema is characterized by a well-demarcated swelling on the skin, oropharyngolaryngeal tissue, or the gastrointestinal wall. Underlying mechanisms may include IgE-mediated reactions, complement activation, inhibition of the cyclo-oxygenase pathway of arachidonic acid metabolism, direct release

Twelve patients with varying degrees of peripheral atherosclerotic disease were given an antiaggregatory drug, ticlopidine [5-(6-chlorobenzyl)-4,5,6,7-tetrahydrothieno-(3,2-C)-pyridine HCl] in a single blind trial for one or four months and the effects on platelet aggregation, blood coagulation,

The probable involvement of prostaglandins in the myoelectrical response of the antrum pylori and small intestine to endotoxin (LPS) was studied in the piglet. In these experiments the influence of I.V. infusion of PGF2 alpha and PGE2 and of I.V. injection of LPS, without and with indomethacin

Molds include all species of microscopic fungi, the spores of which are small molecules, ubiquitous, mostly found in soil with higher rainfall and high humidity, in the atmosphere of urban and rural settings and in decaying vegetation. They originate from pathogenic fungi and have a crucial role in

BACKGROUND To test the hypothesis that urinary levels of arachidonic acid metabolites may be a predicting factor of the effects of pranlukast, a selective leukotriene (LT) antagonist, on chronic adult asthma, we investigated the relationship between its clinical efficacy and urinary eicosanoid

Menstrual pain (dysmenorrhea) is one of the main complaints in clinics for women. The pain is often accompanied by other symptoms such as headache, nausea, constipation or diarrhea, urinary frequency, and vomiting which often leave the patients incapacitated for work or school for a few days.

A food poisoning case due to the ingestion of 'ogonori', an edible red alga, occurred at Yokohama, Kanagawa Prefecture, Japan, in late October 1993, resulting in two victims, including one death (female). No causative agent present in the ogonori was found from a routine bioassay for marine toxins.

Sulfasalazine is metabolized by intestinal bacteria, resulting in the release of sulfapyridine and 5-aminosalicylate. The drug is useful in the treatment of active ulcerative colitis as well as in preventing relapses of the disease in remission. Although effective in active Crohn's disease as well,
