[The measurement of proteins with major involvement in the immunological process in a group of 100 elderly patients]. / Dozarea unor proteine cu implicatii majore în procesul imunologic la un lot de 100 bolnavi vîrstnici.

Alpha-2-macroglobulin, alpha-1-antitrypsin and prealbumin were studied comparatively in 100 patients aged between 60 and 90 years and a series of patients aged 25-45 years. Prealbumin was low in both groups, alpha-2-macroglobulin was higher and alpha-1-antitrypsin was lower in the elderly patients.
