Adrenergic and dopaminergic response to chronic chair restraint in the rhesus monkey

Psychosomatic Medicine
M J PerlowR J Wyatt


Prolonged chair restraint and social isolation in the rhesus monkey led to a reduction in the urinary excretion of HVA (4-hydroxy-3-methoxyphenylacetic acid), DOPAC (3,4-dihydroxyphenylacetic acid), VMA methoxy-4-hydroxymandelic acid), and MHPG (3-methoxy-4-hydroxyphenylethylglycol) over a 3 week period. This adaptation to a chronically "stressful" situation corresponds to earlier studies on the rhesus monkey indicating a gradual reduction in the urinary excretion of norepinephrine and epinephrine after initiation of restraint. The following basic information on the urinary excretion of catecholamine metabolites was obtained: (1) the rate of excretion of the dopamine metabolites (HVA and DOPAC) is about four times higher than the rate of excretion of adrenergic metabolites (VMA and MHPG): (2) MHPG is the major adrenergic metabolite in the rhesus monkey; and (3) the excretion rates of the urinary metabolites varied considerably between animals.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
