As we shall see below, the denial of the causal interaction of substances forms an essential premise of Leibniz's argument for pre-established harmony.
Such a concept requires the generation of a large number of substance-specific data that provide information about the interaction of substances with the organism, e.g. via in vitro systems.
(See the Sixth Meditation: AT VII 86 87/CSM II 59 60) But Leibniz also saw pre-established harmony as an account of the mind-body relation that avoided the difficulties inherent in Occasionalist theories of the mind and the interaction of substances.
In terms of Wolff's distinctions, these disputes can be framed as disputes between (a) monists and dualists and (b) idealists and materialists; positions in this debate were often influenced by perplexities surrounding the (ontological) question of the interaction of substances, although they were also influenced by the (epistemological) debate over innatism.
CI < 1 reflects synergistic inhibition of the respective inflammatory parameter; if CI = 1 the substances have additive interactions; when CI > 1 the interaction of substances reflects antagonism.
(5) There are further interactions of substances, e.g. musk compounds are known to inhibit cellular xenobiotic export systems [17].
As Saussure analogised, language is like the waves we see at the beach – since waves are neither the amorphous body of water below nor the amorphous air movement above but rather the interaction of one substance with the other ("the waves resemble the union of coupling of thought with phonic substance" (Saussure 1916/1966: 1916/1966
The interaction of the substance with NMDA receptors was also studied.
That is, the effects not only become less common with progressively lower doses, they also become less severe, or even adaptive, until a level of interaction of a substance with a biological system is reached that has no ability to perturb the tissues in question from their normal function.
Two physiological functions of the bronchiolar surfactant might play an important role in the interaction of carcinogenetic substances of the lung: The clearance of inhaled particles or substances and their encoating by surfactant.
