Effect of Viscosity on Drug Absorption

Journal of Pharmaceutical Sciences, 1965
The effect of viscosity on the absorption rate of two model drugs (ethanol and salicylic acid) from the stomach of rats has been determined. The two drugs were administered simultaneously, dissolved in an aqueous solution containing 0, 1, or 1.5 per cent methylcellulose (Methocel 4000, 60 HG.). These solutions had a range of viscosities from about 1 to

The Effective Viscosity of Polar Fluids

Transactions of the Society of Rheology, 1970
The effective viscosity of a polar fluid is a measure of the amount of traditional shear viscosity the polar fluid will appear to possess in a particular flow situation. Four classical flow configurations are considered here; Couette flow, plane Poiseuille flow, pipe flow, and flow between concentric rotating cylinders.

Gas Viscosity Effects in Anesthesia

Anesthesia & Analgesia, 1980
The viscosity effects when carrier anesthetic gases are passed through ventilators can lead to significant alterations in ventilating volumes. This effect was studied in both experimental and clinical situations using the Bird anesthetic machine powered by a nitrous oxide-oxygen blender and fitted with a Wright gas-volume meter.

Effects of lipoproteins on plasma viscosity

Atherosclerosis, 1981
Patients with hypertriglyceridemia and mixed hyperlipidemia have been found to have mean plasma viscosities significantly higher than controls (P less than 0.005). In a group of 70 hyperlipidemic patients and controls, plasma viscosity was correlated with plasma triglyceride concentration (r = 0.56, P less than 0.01) and to a lesser extent with the ...

Effect of viscosity on learned satiation

Physiology & Behavior, 2009
A higher viscosity of a food leads to a longer orosensory stimulation. This may facilitate the learned association between sensory signals and metabolic consequences. In the current study we investigated the effect of viscosity on learned satiation. In two intervention groups a low viscosity (LV) yogurt (n=24) and a high viscosity (HV) yogurt (n=22 ...

The Effect of Sweeteners on Perceived Viscosity

Chemical Senses, 1995
Two different sweeteners, sucrose and aspartame, were matched in perceived sweetness intensity. These solutions were thickened with carboxymethylcellulose to six different viscosity levels. Sucrose and aspartame appeared to decrease perceived viscosity of the solutions at a specific sweetener concentration, at all viscosity levels. However, in a second

Effect of α-actinin on actin viscosity

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1971
Abstract As determined by analytical ultracentrifugation, purified α-actinin does not form stable complexes with G-actin, myosin, tropomyosin, or the tropomyosintroponin complex. However, α-actinin forms a stable complex with F-actin polymerized either in 100 mM KC1 or in 2mM MgCl 2 without KCl.

Correlation of the effective and complex dynamic viscosities of viscose

Polymer Mechanics, 1975
The results of comparative measurements of viscosity of viscose in the steady-state flow and harmonic vibration regimes are presented. It is shown that in order to describe the dependence of the effective viscosity on the velocity gradients in the steady-state flow regime it is possible to employ the mathematical apparatus of the phenomenological ...

Extensional Viscosity Effects in EOR

Proceedings of SPE Annual Technical Conference and Exhibition, 1988
ABSTRACT Evidence is first advanced that some polymeric displacement fluids of potential use in EOR experience abnormally high resistance in extensional flows. Since flow through a porous medium involves a substantial extensional flow component, it may be argued that there is justification for studying the effect of this high extensional-

Effective Viscosity of Magnetic Fluids

Journal of the Physical Society of Japan, 1990
Effective viscosity of magnetic fluid is calculated numerically based on the diffusion equation for the spherical particles with permanent magnetic moment. The result is compared with that of the classical constitutive equation proposed by Shliomis. It is found that unlike Shliomis's equation, the viscosity remains monovalued as a function of the shear
