THE exchange of water between blood and eye fluids is very rapid (Kinsey, Grant, and Cogan, 1942) in comparison with the migration of sodium chloride across the blood aqueous barrier. Consequently, on making the blood hypertonic by the intravenous injection of sodium chloride, water should be withdrawn from the eye, and the intra-ocular pressure lowered. Qualitatively, such an effect has been d...

The coordination chemistry of oxotitanium(IV) or titanyl(IV), TiO2+, has been studied in solution by X-ray methods. The titanyl(IV) ion hydrolyzes easily in aqueous systems to solid titanium dioxide as long as it is not stabilized through complexation. In this study the structures of the hydrated bissulfatotitanyl(IV) complex and the dimethylsulfoxide (DMSO) solvated titanyl(IV) ions have been ...

Anterior chambers of the eyes of male rats were cannulated under pentobarbital anesthesia for intracameral infusions of balanced salt solution (BSS) and intraocular pressure (IOP) recording. Blood pressure was recorded from a femoral artery. IOP was recorded during a 2-h intracameral infusion composed of a constant component (0.05 microl/min) and a periodic component (0.25 microl/min), cycling ...

Patients with rheumatoid arthritis have been treated alternately with aurothioglucose and aurothiomalate. In the earlier part of the study an oily suspension of aurothioglucose and an aqueous solution of aurothiomalate were used, but later an aqueous solution of aurothioglucose was alternated with the oily suspension and an oily suspension of aurothiomalate with the aqueous solution. Skin erupt...

We previously reported the preparation of a self-assembled chitin nanofiber (CNF) film via regeneration from an ion gel with an ionic liquid, followed by sonication and filtration. Based on the finding that CNFs were redispersed in a mixture of the film with ammonia aqueous solution (aq.), in this study, CNF-natural rubber (NR) composite sheets were fabricated by mixing redispersed CNF with NR ...

â  abstract: in this work, the kinetics of ethane hydrate formation has been studied experimentally and a kinetic model based on chemical affinity has been described for predicting the hydrate growth process in the stirred batch reactor at a constant volume. the experiments were done with both pure water and aqueous solution of sodium dodecyl sulfate (sds). the effect of sds on formation kineti...
