[Beta-glucuronidase in blood serum of patients with contagious mononucleosis].

The activity of beta-glucuronidase in blood serum of 12 women and 14 men ill from contagious mononucleosis in the first and third week of hospitalization was determined after the method given by Krawczyński. Moreover, there were determined: the number of leucocytes, percentage of normal lymphocytes including atypical ones, the activity of aminotransferases (asparagine and alanine), as well as Paul-Bunnell-Davidsohn's reaction. It was found that the level of beta-glucuronidase during the first week of hospitalization increased, and it decreased in the third week, which may be one of the indices of convalescence, independently of the sex of the examined persons.
