Abstract

The rate of neutralization of acid by spray-dried products bound with gum arabic, gelatin, polyvinyl alcohol, carboxymethylcellulose, methylcellulose, and polyvinylpyrrolidone was investigated to evaluate antacid and timed-release properties. A double-layer model was assumed to analyze the neutralization velocity. Diffusion and the reaction layers at the interface between solid and liquid were considered, and an acid neutralization rate equation was developed. The mass transfer coefficient and reaction rate constant for acid neutralization were determined to be 9.3 × 10−3−7.0 × 10−2 cm sec−1 and 400–500 cm3 sec−1, respectively. The percentage of spray-dried particles coated with binder was 80% for carboxymethylcellulose and 48–65% for gelatin, methylcellulose, and polyvinyl alcohol products. Gum arabic and polyvinylpyrrolidone products proved to be only agglomerated. Tableting the powdered spray-dried products increased the proportion of encapsulated material from 48–83 to 70–98%, and their timed-release capacity was greater than that prior to tableting.

Abstract

The kinetics of spherical agglomeration in a stirred vessel was investigated using sands, dispersed in agitated carbon tetrachloride and agglomerated with calcium chloride aqueous solutions, as a model system. The effects of stirring speed, baffles, solids loading, particle size and bridging liquid concentration were studied. It was found that agglomerate growth could be described by first-order kinetics, at least for the initial part of the process which is of most interest from the point of view of industrial applications. Particle aggregation and the relatively high solids concentrations used apparently accounted for this “restricted-in-space” behaviour. Empirical correlations were developed to relate the parameters in the kinetics equations to the experimental conditions.

Abstract

The response of plasma cortisol, corticosterone and non-protein-bound cortisol in the extracorporeal circulation was investigated in 14 patients. The pre-perfusion levels of plasma cortisol, corticosterone and non-protein-bound cortisol were significantly elevated. During and immediately after perfusion, the levels of cortisol and corticosterone were found to decrease significantly from the pre-perfusion levels, while the percentage of non-protein-bound cortisol was shown to increase significantly. This indicates a marked decrease in cortisol binding capacity of plasma during extracorporeal circulation. Moreover in 200 plasma samples, it was demonstrated that the cortisol level increased markedly and the cortisol binding capacity decreased slightly during and shortly after major surgery without perfusion. It is concluded that stressful situations in major surgery with or without perfusion are associated with markedly increased levels of biologically active non-protein-bound cortisol. The elevated level of non-protein-bound cortisol in surgery seems to be dependent on the increase in the level of plasma cortisol as well as on the decrease in the cortisol binding capacity of plasma. Although the increased plasma cortisol plays the most important role in surgery with no perfusion, the decreased cortisol binding capacity may be the more effective factor involved during perfusion.
