Comparison of the temporal profiles of vasopressin and oxytocin in the cerebrospinal fluid of the cat, monkey and rat.
The temporal profiles of oxytocin were examined in the cerebrospinal fluid (CSF) of the cat and rat. Unlike the marked daily rhythm of oxytocin concentrations recently described in the CSF of the rhesus monkey, no daily rhythm of the peptide was evident in the CSF of either the cat or rat. The apparent species specificity of the CSF oxytocin profiles among these mammals is contrasted with the consistent expression of a daily rhythm of arginine-vasopressin in the CSF of each of the three species.
