The effects of chemical sympathectomy on dopamine, noradrenaline and adrenaline content in some peripheral tissues.

abstract：:1. Chronic benzodiazepine administration has been associated with tolerance and with downregulation of gamma-aminobutyric acidA (GABAA)-receptor binding and function. However, effects of individual benzodiazepines on brain regions have varied. 2. To compare the effects of chronic lorazepam and alprazolam, we have admi...
