title: Cytochemical examination of peripheral blood lymphocytes in bursectomized chickens.
abstract: The starting material were 86 day-old utility hybrid Tetra SL chicks. Beginning from their third week of life, 59 chickens were kept in two separate rooms "A" and "B" for 42-56 days. The values of temperature and cooling were somewhat different in rooms "A" and "B", however essentially not deviating from the accepted zoohygienic norms. The obtained results revealed a significant reduction of the activity of acid phosphatase in blood lymphocytes of 8-10 week-old chickens bursectomized in the neonatal period and kept in room "A". No such changes were found concerning ATP-ase and 5'-nucleotidase. Similar effect appeared in the lymphocytes of non-bursectomized chickens kept in room "B". Antigen stimulation (SRBC) of bursectomized and non-bursectomized chickens brought about an increased activity of all the three enzymes in blood lymphocytes. At the same time it should be emphasized that the increased activity of the enzymes tested was modulated by bursectomy and conditions of the medium.
