The role of cyclic AMP in histamine release induced by human leukocyte lysates was investigated. Leukocytes were incubated with leukocyte lysates prepared by ultrasonic disruption, and histamine was determined fluorimetrically. Several cyclic AMP-active agents had a marked inhibitory effect on histamine release. Theophylline and isoproterenol produced 50% inhibition at concentrations of less th...
in this research, the kinetics of carbothermic reduction of molybdenite in the presence of sodium carbonate was studied. For this purpose, mixed powder of molybdenite, graphite, and sodium carbonate with 1:4:2 mole ratio was investigated using simultaneous thermal analysis (STA) at the heating rates of 10, 15 and 20 0C /min. The results of thermal analysis were evaluated through Friedman, Kissi...
The present investigation summarizes the effect of Linum usitatissimum fixed oil against different phases of acute inflammatory reaction, namely, protein exudation, peritoneal capillary permeability, and leukocyte migration. The fixed oil exhibited dose-dependent inhibition of protein exudation vascular permeability, comparable to standard aspirin. The oil also inhibited the leukocyte migration...
Several members of a series of N-(fluorenyl-9-methoxycarbonyl) amino acids were found to possess a broad spectrum of antiinflammatory activity. The compounds were active against oxazolone dermatitis in mice and adjuvant arthritis in rats, models in which activated T lymphocytes are implicated. The compounds also inhibited T-lymphocyte activation in vitro, assessed by using the mixed lymphocyte ...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
The mixed lymphocyte reaction is characterized by proliferation and generation of specifically cytotoxic effector lymphocytes. These two phases of the mixed lymphocyte reaction have been shown to be mediated by distinct subpopulations of thymus-derived cells. The current investigation demonstrates that combinations of cells from thymus and lymph nodes of CBA mice exhibit synergism with respect ...
