[Immunocytologic detection of peptides immunologically related to LRH and to SRIF in the garden dormouse under various conditions].
Immunocytologic technics have allowed us to detect appreciable and progressively increasing amounts of LRH and of SRIF in the median eminence of the dormouse during hibernation at 6 degrees C. In animals conditioned to darkness at 22 degrees C with the ovarian involution that is very important, there exists a nearly total disappearance of LRH while the amount of SRIF remains high. On the contrary permanent lighting at 22 degrees C responsible of an important reactivation of the genital sphere provoques a massive accumulation of LHR in the median eminence; SRIF is present in large amounts during the first weeks but diminishes of the experience is prolonged.
