Studies on the Lysis of Leucocytes of Tuberculous

Patients in vitro due to Tuberculin (2nd Part)

Abstract

Experimental studies are made on the lysis of leucocytes of tuberculous patients due to tuberculin and also on the factor which has been introduced by Favour and others. The results obtained are as follows:
1) The factor of the lysis of leucocytes in vitro due to tuberculin is present in blood plasma of the patients.
2)The effective factor in the plasma is destroyed at 56°C,15 min., but it is preserved at 10°C for a week.
3) When serum is used in place of plasma, the lysis of leucocytes is not remarkable.
