The clinical significance of elevated CSF and plasma histamine in cerebral aneurysm surgery utilizing cardiopulmonary bypass with total circulatory arrestAgents and Actions - Tập 23 - Trang 343-347 - 1988
A. Marath, P. Richards, W. Man, K. M. Taylor, C. Lincoln, N. Soni, J. M. Rice-Edwards, A. Bartoli, D. Gladstone
Recently there has been a renewed interest in the neurosurgical treatment of
large cerebral aneurysms and AV malformations utilising cardiopulmonary bypass
(CPB) and total circulatory arrest (TCA). However, the differing tolerance
limits of coagulation and bleeding, pH control and fluid constraint are
difficult to reconcile. Although clinical assessment, electro encephalogram
(EEG) and intracrania... hiện toàn bộ
Intestinal anaphylaxis in the rat: Mediators responsible for the ion transport abnormalitiesAgents and Actions - Tập 28 - Trang 185-191 - 1989
A. G. Catto-Smith, M. K. Patrick, J. A. Hardin, D. Grant Gall
Antigen challenge of jejunal epithelium from rats sensitized to egg albumin
induces an active Cl− secretory process secondary to release of mucosal mast
cell mediators. The present study was designed to define the relative role of
these mast cell mediators and the enteric nervous system in the transport
abnormalities associated with intestinal anaphylaxis. Net ion transport of
stripped jejural tis... hiện toàn bộ
Inhibitory effect of famotidine on cat gastric secretionAgents and Actions - Tập 19 - Trang 188-193 - 1986
G. Coruzzi, G. Bertaccini, M. T. Noci, G. Dobrilla
The inhibitory effect of the novel H2 receptor antagonist famotidine was studied
in conscious gastric fistula cats against dimaprit-induced hypersecretion, in
comparison with ranitidine. On the secretory plateau induced by dimaprit (2 μmol
kg−1 h−1) famotidine (0.05–0.2 μmol kg−1 i.v.) exerted a dose-dependent
inhibitory effect, being approximately 4.5 times as potent as ranitidine (ID50
values we... hiện toàn bộ
H1-receptor dependent increase in platelet aggregation is mediated by intracellular calciumAgents and Actions - Tập 36 - Trang C402-C405 - 1992
P. F. Mannaioni, A. Pistelli, M. G. Di Bello, F. Gambassi, E. Masini
The influence of histamine on human platelet function was studied by measuring
the uptake of [3H]-histamine and by evaluating the effect of histamine on Ca2+
influx and on intracellular Ca2+ levels. The uptake of histamine by platelets is
significantly reduced by mepyramine and unaffected by cimetidine. Histamine was
found to increase both the [45Ca]2+ uptake by resting and stimulated platelets,
a... hiện toàn bộ
FcγRIIa requires lipid rafts, but not co-localization into rafts, for effector functionAgents and Actions - Tập 62 - Trang 37-43 - 2012
Joshua A. Vieth, Moo-kyung Kim, Daniel Glaser, Kaitlyn Stiles, Alan D. Schreiber, Randall G. Worth
To determine if receptor localization into lipid rafts, or the lipid rafts
themselves, are important for FcγRIIa effector functions. Wild-type FcγRIIa or
mutant FcγRIIa(C208A) that does not translocate to lipid rafts were transfected
into Chinese hamster ovary (CHO) cells which have been shown to be reliable
cells for studying FcγR function. Cells were treated with buffer or
methyl-β-cyclodextrin ... hiện toàn bộ
Azelastine inhibits stimulated histamine release from human lung tissuein vitro but does not alter cyclic nucleotide contentAgents and Actions - Tập 28 - Trang 16-21 - 1989
M. M. Little, D. R. Wood, T. B. Casale
To investigate the mechanism by which azelastine may be effective
therapeutically in asthma, we studied its ability to inhibit anti-IgE- and
calcium ionophore A23187-stimulated histamine release from human lung and to
alter lung cyclic nucleotide levels. Significant inhibition of histamine release
from both anti-IgE- and A23187-stimulated human tissue was aparent after 30
minutes preincubation of ... hiện toàn bộ
