[Role of vasopressin in regulating the volume and ionic composition of cerebrospinal fluid].
In chronic experiments on dogs with cannulae implanted in the lateral cerebral ventricle and occipital cistern, the CSF volume and Na+, K+ concentrations were measured during osmoregulating reaction and pituitrin infusion in the lateral ventricle. Isoosmotic CSF volume decrease in both experimental groups indicates that water-salt regulation in the body and brain tissues is performed by means of common neuro-humoral mechanisms with vasopressin participation.
