Chronic Stress Enhances the Corticosterone Response and Neurotoxicity to +3,4-Methylenedioxymethamphetamine (MDMA): The Role of Ambient Temperature

Journal of Pharmacology and Experimental Therapeutics July 16, 2010 Bethann N. Johnson, Bryan K. Yamamoto 22 citations

Prior exposure to chronic unpredictable stress (CUS) in rats amplifies the hyperthermia, corticosterone (CORT) secretion, and long-term depletion of serotonin (5-HT) in striatum, hippocampus, and frontal cortex and dopamine (DA) in striatum caused by the psychostimulant MDMA. Lowering ambient temperature to 21°C prevented these augmented effects in stressed rats, reducing them to levels seen in nonstressed, MDMA-treated animals. Blocking CORT secretion with metyrapone did not alter the monoamine depletions, indicating that the stress-induced enhancement of MDMA neurotoxicity is mediated by hyperthermia rather than by CORT itself.

Disposition of 14C-mescaline by rabbit lung.

Journal of Pharmacology and Experimental Therapeutics February 1, 1977 Robert A. Roth, Jan Roth, C. N. Gillis 17 citations

Rabbit lung tissue metabolizes mescaline four times more actively than liver or kidney tissue, while brain and plasma have little capacity to break it down. The metabolism is inhibited by semicarbazide. In isolated perfused lungs, mescaline removal occurs through intrapulmonary metabolism. Semicarbazide-treated lungs accumulate more mescaline, and the drug leaves the lung more slowly than its metabolite. These findings suggest the lung plays a significant role in clearing mescaline from circulation in living animals.
