Abstract
1. Bursa-intact and bursectomized chicks were exposed to cold-wet immobilization (CWI) stress for 1.5 min. The catecholamines (CA) from the adrenal gland were measured spectrofluorometrically 5, 15, 30 and 60 min after stress. 2. In bursa-intact chicks, the CWI stress caused decrease of both norepinephrine and epinephrine from the adrenal glands 5 min after stress. Resynthesis of epinephrine exceeded the control value 30 and 60 min after stress. 3. In bursectomized chicks, the CWI stress brought about a decrease of norepinephrine 15 and 30 min and of epinephrine 30 and 60 min after stress. 4. The findings suggest that bursa facilitates early (5 min) release of CA and also helps in quick resynthesis of epinephrine during stress.
