Pulp was experimentally inflamed by applying bacterial lipopolysaccharide (LPS). Changes in arachidonic acid (AA) metabolites were determined by measu Cited by: ALOX15 (also termed arachidonate lipoxygenase, lipoxygenase-1, LO-1, LOX-1) is, like other lipoxygenases, a seminal enzyme in the metabolism of polyunsaturated fatty acids to a wide range of physiologically and pathologically important products.

Gene Function. Kelavkar and Badr () stated that the ALOX15 gene product is implicated in antiinflammation, membrane remodeling, and Aliases: ALOX15, LOX, LOX-1, 15LOX-1.

The cited metabolites may use one or the other of these two mechanisms in different vascular beds and in different animal species to contribute in regulating regional blood flow and blood pressure. While the role of these metabolites in the human vasculature has not been studied, 12 S -HETE, 12 R -HETE, HxA3, TrXA3, and TrXC3 do inhibit the CAS Number: 14 C-Arachidonic Acid Metabolism.

In order to identify the arachidonic acid metabolites produced by female and male pulmonary arteries, segments of intrapulmonary artery (70 mg of wet weight) were incubated in HEPES buffer (in mmol/L: HE NaClKCl 5, CaCl 2 2, MgCl 2 1, and glucose 6, pH ) containing 14 C-arachidonic acid ( μCi, 10 −7 mol/L) and the calcium ionophore Cited by: The most effective and safe treatment site for pain is in the skin.

This chapter discusses the reasons to treat pain in the skin. Pain is sensed in the skin through transient receptor potential cation channels and other receptors. These receptors have endogenous agonists (yang) and antagonists (yin) that help the body control pain.

Acupuncture works through modulation of these receptor Cited by: 4. Retinopathy of prematurity (ROP) is a common retinal disease in preterm babies.

Many of the physiological roles of lipoxygenases are still unknown, but 5-lipoxygenase is involved in leukotriene metabolism, lipoxygenase in the angiotensin pathway, and lipoxygenase in reticulocyte maturation/5.

A widely used anti-inflammatory agent isolated from the licorice root. It is metabolized to glycyrrhetic acid, which inhibits 11 beta-hydroxysteroid dehydrogenase and other enzymes involved in the metabolism of corticosteroids. Therefore, glycyrrhizic acid, which is the main and sweet component of licorice, has been investigated for its ability to cause hypermineralocorticoidism with sodium.

The Fifth Congress was developed around themes relating to ocular drug metabolism, the ocular pathophysiological effects of nitric oxide, government issues relating to the use of alternative methods for toxicity testing, and a workshop that encompassed comparisons of both in vitro versus in vivo models as well as different animal models.

In addition to inhibition of the endocrine secretions, somatostatin has direct effects on a number of target organs (9). For example, it is a potent inhibitor of basal and prostaglandin-stimulated gastric acid secretion.

It also has marked effects on GI transit time, intestinal motility, and absorption of nutrients from the small intestine. The present invention provides methods and compositions for improving the effectiveness of suboptimally administered drug therapy and / or for reducing side effects.
