PULSAR analysis of pulse characteristics

Treatment	Pulse number	Pulse height (ng/ml)	Pulse length (h)	Pulse area (ng/ml)	Interpulse interval (h)	Pulse frequency (no. pulses/h)
CONTROL-SAL	9.2 ± 0.6	70.1 ± 5.7	0.62 ± 0.03	19.1 ± 1.4	1.23 ± 0.07	0.78 ± 0.06
ACTH -PULS	7.7 ± 0.9	83.1 ± 13.5	0.53 ± 0.06	20.6 ± 4.8	1.46 ± 0.21	0.65 ± 0.07

Shown are mean ± sem of pulse height, interpulse interval, pulse frequency, pulse length, and pulse area analyzed using the PULSAR algorithm calculated from 12-h corticosterone profiles during the peak phase of corticosterone secretion (1500–0300 h) of control rats infused with saline (CONTROL-SAL) and rats treated with MP for 5 d and infused with pulsatile ACTH (4 ng/h, 5 min pulse, ACTH PULS) for 24 h.
