Drug-Induced Changes of Plasma Gastrin Concentration

Gastroenterology Clinics of North America, 1990
There is a significant inverse relationship between intragastric acidity and plasma gastrin concentration. All generally available gastric acid antisecretory drugs induce a release of gastrin into the circulation. The more potent the gastric antisecretory dosage regimen or drug, the greater the rise of plasma gastrin concentration.

Non-Diffusional Concentration Changes

1981
In this chapter we lump together the really quite uncomplicated complications of homogeneous chemical reaction kinetics and convective transport. There is nothing conceptually difficult with kinetics; the only problems encountered are due to reactions proceeding too fast or, in multi-step reactions, having to account for a number of reaction species ...

Change in concentration with time

Journal of Chemical Education, 1985
Shows how the rate of a reaction is fast at first and then gradually decreases to zero when one reactant has been used up.

Advertising and Changes in Concentration

Southern Economic Journal, 1969
The effect of advertising on industry structure and firms' behavior is a topic which has stimulated much discussion, a limited number of hypotheses and still fewer empirically verified propositions. One well-known hypothesis, originally put forth by Kaldor, is that advertising will result in increasing industry concentration thereby affecting ...

Developmental changes in brain kynurenic acid concentrations

Developmental Brain Research, 1992
The cerebral distribution and regulation of excitatory amino acid levels may play a crucial role in neuronal development. In the present study we examined concentrations of the endogenous excitatory amino acid antagonist kynurenic acid and related substances during development in fetal and neonatal rat brain and fetal non-human primate cerebral cortex.

[Changes in platelet concentrates from dogs due to storage. II. Biochemical changes in concentrate plasma].

Berliner und Munchener tierarztliche Wochenschrift, 1999
Platelet concentrate (PC) obtained from dogs with an automatic cell separator was stored in C4-cell separation sets with low gasdiffusionable Polyvinylchlorid (PVC) storage containers or in C4L-sets developed for storage with high gasdiffusionable Polyolefin(PO) containers, respectively.
