Table 1.

Absolute concentrations of stress protein and hormones before and after the heat stress.

Protein and hormones	Before Heat	After Heat
HSP72 (ng/ml)	2.82 ± 2.07	3.79 ± 2.29 *
PRL (ng/ml)	7.60 ± 4.29	25.7 ± 11.8 *
NE (pg/ml)	523.3 ± 237.2	768.9 ± 333.7 *

HSP72 = heat stress protein 72. PRL = prolactin. NE = norepinephrine.

The asterisks indicate that there were significant (p < 0.05) increases after the prior passive heat stress. The whole body heat stress at 73 deg C for 30 min increased the HSP72, PRL and NE levels.
