Reversible and irreversible inhibition of rat brain muscarinic receptors is related to different substitutions on bisquaternary pyridinium oximes.

abstract：:This review encompasses the most important advances in liver functions and hepatotoxicity and analyzes which mechanisms can be studied in vitro. In a complex architecture of nested, zonated lobules, the liver consists of approximately 80 % hepatocytes and 20 % non-parenchymal cells, the latter being involved in a seco...
