Cromoglycate and nedocromil enhanced the reactive oxygen species‐dependent suppressions with, but not without, dexamethasone in ischaemic and histamine paw oedema of mice

Mediators of Inflammation, Volume 6, Issue 5-6, Page 369-374, 1997., 1997
Anti‐inflammatory actions of two anti‐allergic drugs, alone or with dexamethasone (Dex) were examined in two models, because inflammation is claimed to be important for allergic events, especially for asthma. Cromoglycate and nedocromil were tested in ischaemic‐ and histamineinduced paw oedema models of mice. These antiallergic drugs (1–100 mg/kg, i.p.)

Redução de cromo hexavalente por bactérias isoladas de solos contaminados com cromo [PDF]

Ciência Rural, 2007
A redução do Cr(VI) para Cr(III) diminui a toxidade deste metal no ambiente, uma vez que o Cr(III) é insolúvel às membranas biológicas. Assim, a redução microbiana do Cr(VI) é uma alternativa para reduzir os impactos ambientais causados por este metal, utilizado em diversos processos industriais.

NSAIDs in the Treatment of Adult Asthma: Sodium Cromoglycate and Nedocromil Sodium

Canadian Respiratory Journal, Volume 2, Issue A, Page 19A-23A, 1995., 1995
Among nonsteroidal anti‐inflammatory drugs used in the treatment of adult asthma, sodium cromoglycate and nedocromil sodium are the most frequently prescribed. These medications have a similar efficacy profile in asthma although it has been suggested that nedocromil is more powerful than cromoglycate, particularly in its steroid sparing effects.

Magnetic and Paleomagnetic Characterization of the Ivrea‐Verbano Lower Crust Body (NW Italy): Assessing the Magnetization of Variscan‐Age Lower Crust

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract The source of high‐intensity magnetic anomalies from (mostly Precambrian) lower crust of continent interiors has long been debated, as it requires speculative rocks yielding 2–6 A/m magnetization. We report on the magnetic and paleomagnetic investigation of the Ivrea‐Verbano Zone (IVZ), Western Alps, where metamorphic and intrusive lower crust

Ecotoxicological tests with cadmium and chromium using postlarvae of silverside Odontesthes (Austromenidia) regia regia Hildebrand

Revista Peruana de Biología, 2014
In the present paper, the mean effective concentrations (EC50%) of cadmium (Cd+2) and chromium (Cr+6) using postlarvae of the silverside fish Odontesthes (Austromenidia) regia regia were determined. The postlarvae were exposed to different concentrations
