[Dynamic interphase tensiometry of the cerebrospinal fluid and blood serum in nervous system tumors]. / Dinamicheskaia mezhfaznaia tenziometriia spinnomozgovoi zhidkosti i syvorotki krovi pri opukholiakh nervnoi sistemy.

Dynamic superficial tension (ST) of spinal fluid (SF) and blood serum in patients with CNS tumors was investigated. The maximum bubble tension was measured by a MPT2 computer tensiometer (LAUDA). There were decreases in ST of blood serum at t = 1 and t-->infinity, increases in ST at t = 0.01 and decreases in the angle on SF tensiograms. The parameters of interphasic tensiometry of the biological fluids depend on content of biologically active substances severity of the neurological symptomatology and duration of disease. Successive surgical treatment is followed by normalization of SF and blood serum ST.
