The circadian variation of immunoreactive lipotrophin and its relationship to ACTH and growth hormone in man.
There is a clear circadian rhythm of plasma immunoreactive LPH in man with the trough occurring between 22.00 h and 03.00 h and the peak between 07.00 h and 08.00 h, immediately after waking. At all times circulating LPH and ACTH levels follow each other closely. However, no correlation was observed between LPH levels and either plasma GH or the stage of sleep.
