Abstract
The cerebrospinal fluid (CSF) system has been described as a moderately distensible compartment, wherein pressure is maintained within relatively narrow limits.1 The principal components regulating CSF dynamics are synthesis rate, compliance, and drainage (mainly at arachnoid villa). Angiotensin2 and vasopressin3 have been associated with choroid tissue, although a role for the peptides has not emerged; both peptides are endogenous to CSF.4 Vasopressin, in anesthetized rabbits, reduced CSF pressure most likely by facilitating CSF transport to venous blood.5 This peptide may also alter intracranial water movement.6 Angiotensin has been reported to cause cerebral vasoconstriction by a central mechanism.7 Thus, the peptides may affect intracranial pressure.
