Preclinical detection of nephrotoxicity: description of the tests and appraisal of their health significance.

abstract：:Interactions of chemicals with cerebral neurotransmitters, receptors, and second messenger systems are often accompanied by similar changes involving components in non-neural tissues. On this basis, indirect strategies have been developed to investigate neural cell function parameters by methods using accessible cells...
