Determination of lorazepam in plasma by electron capture GLC.

abstract：:In the recent years, the toxicity of certain divalent cations has been associated with the alteration of intracellular Ca2+ homeostasis. Among other mechanisms, these cations may affect the functionality of certain Ca2+-binding proteins and/or Ca2+ pumps. The plasma membrane calcium pump (PMCA) maintains Ca2+ homeosta...
