The effect of a single dose of sheep's erythrocytes on the activity of acid phosphatase in lymphocytes of peripheral blood in bursectomized chickens.

Tangible decrease of acid phosphatase activity was found in lymphocytes of peripheral blood in 14-week old chickens bursectomized neonatally. This observation confirms earlier suggestions concerning decreased activity of this enzyme which has been observed after bursectomy. In the investigations performed stimulation of the chickens with sheep's erythrocytes caused a significant increase of acid phosphatase activity in blood lymphocytes of bursectomized birds. However the increase of enzyme activity was lower than that observed in nonbursectomized chickens.
