Previous studies have shown that inhibition of the lipoxygenase pathway of arachidonic acid metabolism can prevent the development of elevated blood pressure in renin-dependent models of hypertension. Agents that inhibit the lipoxygenase pathway such as phenidone and the flavonoid baicalein

1. In the absence of indomethacin, anandamide did not contract the guinea-pig bronchus at concentrations up to 100 microM. In the presence of indomethacin (10 microM), anandamide induced concentration-related contractions with a pEC(50) value of 5.18+/-0.11. It was significantly less

The immunomodulatory agent RU 41740 (Biostim), which is derived from Klebsiella pneumoniae, may augment mitogenic responses of purified human blood lymphocytes. In non-purified preparations, however, responses may be sharply reduced due to the fact that Biostim induces monocytes to secrete

The possible involvement of products of the lipoxygenase pathway of arachidonic acid cascade in ovulation was tested by intrabursal injection of nordihydroguaiaretic acid (NDGA); 5, 8, 11-eicosatriynoic acid (5, 8, 11-ETYA), 3 amino-1-(3 trifluromethyphenyl)-2-pyrazoline hydrochloride (BW755c) and (FPL 55712).

Rationale: The role of inspiratory effort still has to be determined as a potential predictor of noninvasive mechanical ventilation (NIV) failure in acute hypoxic de novo respiratory failure.Objectives: To explore the hypothesis that inspiratory effort might be a major determinant
