Detection of ethanol in urine of abstaining alcoholics.

abstract：:Many functions of the brain and the sympathetic adrenal system are influenced by those amino acids that exert precursor control over neurotransmitter synthesis. One of the functions affected is regulation of blood pressure. Therefore, the purpose of this review is to describe how food proteins and amino acids affect t...
