Creo que "liquor" se usa de forma genérica para referirse a cualquier líquido o fluido del cuerpo pero también específicamente para el "líquido cefalorraquídeo". ¿Puede ser este el caso? Aquí pongo algunos ejemplos. Gracias de antemano. - "The Met-ENK immune reactivity in plasma of patients suffering from a brain infarctus in the acute phase and diabetes patients with symptomatic myocardiac ischemia is significantly increased as compared to healthy control individuals, as well as in plasma and liquor of patients suffering from migraine and headache and in liquor of schizophrenia patients." - "In Parkinson's disease the content of Met-ENK-Arg-Gly-Leu in liquor of patients is significantly decreased as compared to healthy control individuals." - "In healthy individuals liquor contains 150 to 450 [micro]g of protein per ml, 83 % are formed in the serum and only 17 % in the brain." - "The highest liquor-serum ratio known so far is that of prostaglandin-D-Synthetase having a value of 33." - "As the concentration of proenkephalin like proenkephalin-fp is higher in liquor than in plasma, an increase of proenkephalin in plasma indicates the damage or loss of function of the blood brain barrier: the liquor diffuses into plasma leading to an increase in proenkephalin concentration in plasma."
