Microbial selection on mixtures of chlorinated and nonchlorinated compounds that are poorly soluble in water and/or toxic to growing microbial cells was examined in both biphasic aqueous-organic and monophasic aqueous systems. A biphasic system in which silicone oil was used as the organic phase permitted the acceleration of acclimation, leading to rapid selection and to an increase in xenobiot...

PURPOSE To assess aqueous humor dynamics in mouse eyes. METHODS Aqueous humor dynamics of NIH Swiss White mouse were assessed with an injection and aspiration system, using fine glass microneedles. Intraocular pressure (IOP) was measured by a microneedle connected to a pressure transducer. Episcleral venous pressure (EVP) was measured by gradually lowering intracameral pressure until blood re...

It appears possible to utilize the inorganic phosphorus content in the aqueous humor for estimation of postmortem interval, especially if the factors relating to the body temperature are known in detail.

A parallel artificial lipid membrane system was developed to mimic passive mass transfer of hydrophobic organic chemicals in fish. In this physical model system, a membrane filter-supported lipid bilayer separates two aqueous phases that represent the external and internal aqueous environments of fish. To predict bioconcentration kinetics in small fish with this system, literature absorption an...

A double-blind, randomized, placebo-controlled study of the effect of 0.5% topical thymoxamine hydrochloride an alpha-adrenergic antagonist, on the rate of aqueous humor formation in the eyes of 25 normal human subjects was performed with fluorophotometry. The effect of thymoxamine on intraocular pressure and anterior chamber volume was also studied. four of the 25 subjects were used to study t...
