In the present study, the effects of hypochlorous acid (HOCl), monochloramine (NH(2)Cl), glutamine-chloramine (Glu-Cl) and taurine-chloramine (Tau-Cl) on the formation of 12-lipoxygenase (LOX) metabolite, 12-HETE, and cyclooxygenase (COX) metabolites, TXB(2), and 12-HHT, from exogenous arachidonic acid (AA) in rat platelets

It is shown that 12-(S)-hydroxy-(5Z, 8E, 10E)-heptadecatrienoic acid (5-cis-HHT)--a physiological metabolite of arachidonic acid--is acid-catalyzed converted into a less polar substance with its maximum UV-absorption at (1)max=232 nm and a molar absorptivity of about epsilon=26600 +/- 200 M(-1)cm(-1). Using a
To establish the possible influence of isatin (2,3-dioxo-indole) on the activity of platelets, the effects of isatin on platelet eicosanoid synthesis were studied in rats. Different doses (12.5-50 mg/kg) of isatin were injected intraperitoneally (i.p.) and the effects on the

Both 12-hydroxyheptadecatrienoic acid (12-HHT) and thromboxane A2 (TXA2) are products derived from prostaglandin H2 (PGH2) catalyzed by thromboxane synthase. Whether or not they exhibit similar actions remains to be determined. While TXA2-induced activation of extracellular signal-regulated kinases (ERKs) has been
Environmental health perspectives, 109 Suppl 4, 613-618 (2001-09-07)
Agglomerates of ultrafine particles (AUFPs) may cause adverse health effects because of their large surface area. To evaluate physiologic responses of immune cells, we studied whether agglomerates of 77-nm elemental carbon [(EC); specific surface area 750 m2/g] and 21 nm
