Effect of Chromium-methionine Chelate on Performance and Some Plasma Constituents of Laying Japanese Quail during Summer Months
A 12-wks laying trial was conducted to study the effect of dietary chromiummethionine chelate supplementation on laying Japanese quail (Coturnix coturnix japonica) performance, egg quality, fertility %, hatchability % and some plasma constituents during summer months. A total of 225 laying Japanese quail (150 ♀+ 75 ♂) of 8 wks old were randomly assigned in 5 equal groups of 3 equal replicates e...
متن کاملFluorophotometric detection of intravitreal peroxides after panretinal laser photocoagulation.
PURPOSE To develop a highly sensitive method for in vivo quantitation of intravitreal peroxides by vitreous fluorophotometry with 2',7'-dichlorofluorescin (DCFH), a hydrogen peroxide (H2O2)-sensitive fluorescent dye, and to measure peroxides in the vitreous humor after panretinal laser photocoagulation (PRP). METHODS In the presence of H2O2 and lipid hydroperoxides, nonfluorescent DCFH was ox...
متن کاملFluorophotometric estimation of stilbamidine in urine and blood.
Stilbamidine (4,4’-diamidinostilbene) has been introduced by Yorke and his colleagues (1) as a powerful chemotherapeutic agent for the treatment of trypanosomiasis, kala-azar, and babesiasis. It has also been experimentally used in the therapy of purulent, arthritis (2), simian malaria (3), and most recently in multiple myeloma (4). A method for the estimation of this drug in biological fluids ...
متن کاملFluorophotometric method for the estimation of salicylate in blood.
While salicylates are among the most frequently prescribed drugs, methods for their determination in blood have been neither sufficiently sensitive nor precise. Brodie, Udenfriend, and Coburn (1) have devised a procedure suitable for the clinical measurement of blood salicylate levels if large doses are given. In their method the salicylate is extracted from acidified plasma with ethylene dichl...
متن کاملFluorophotometric quantitation of oxidative stress in the retina in vivo.
PURPOSE To establish a new fluorophotometric method to quantitate oxidative stress in the retina in vivo with a hydrogen peroxide (H2O2)-sensitive fluorescent dye. METHODS For in vitro fluorophotometric study, nonfluorescent 2',7'-dichlorofluorescein (DCFH) was incubated with H2O2 (10 pM to 100 nM), and the production of fluorescent 2',7'-dichlorofluorescein (DCF) was measured with fluorophot...
