    Notes: Summary Primary cell cultures from newborn rat brain hemispheres were exposed to different irrigation fluids used in neurosurgery. The cells died after incubation for 5 min with hydrogen peroxide, and the number of cells was drastically decreased after 10 sec of incubation. They shrank after incubation in Elliott's artificial cerebrospinal fluid for 3 h, but the viability as determined by trypan blue exclusion test was not affected. Physiological sodium chloride, Ringer's solution and the culture medium 199 with Hank's salt had no noticeable effect on the viability or morphology of the cells.

    Notes: Summary Conventional suction systems for neurosurgery are assessed against the background of findings in experimental investigations. Criteria for optimum suction are proposed. The advantages of a modified suction system for neurosurgery are discussed, and recommendations are given.

    Notes: Summary The effect of different irrigation fluids used in neurosurgery and of cortical exposure to air or hydrogen peroxides on the cat brain surface was tested by quantitative assay of extravasated albumen in the cortex and the white matter. Ringer's solution and Elliott's solution B induced no major blood-brain barrier (BBB) dysfunction after closed subdural perfusion for 3 hours. Normal saline induced slight BBB dysfunction extending throughout the cortex into the white matter after the same time of exposure. When these three solutions were applied to the brain surface via pledgets during exposure for 3 hours no further damage was induced. If 15 minutes exposure to air preceded the open perfusion via pledgets with Ringer's solution or Elliott's solution B for 2 hours and 45 minutes, no significant cortical BBB dysfunction was induced. There was a manifold increase in BBB dysfunction after perfusion with Ringer's solution or Elliott's solution B for 2 hours and 45 minutes followed by exposure to three per cent hydrogen peroxide for 5 minutes and a further 10 minutes perfusion with the previous irrigation fluid. Thus, normal saline was found unsuitable for neurosurgical irrigation purposes, due to disturbance of the BBB. Ringer's solution and Elliott's solution B protected the brain adequately even if only applied in pledgets. A short period of exposure to air had no effect on the BBB in the cortex, whilst exposure to hydrogen peroxide was detrimental to the BBB.

    Description / Table of Contents: Zusammenfassung Basisches Myelinprotein im Liquor wurde mit einer radio-immunologischen Methode nach Hirntumorchirurgie in 13 Fällen gemessen. Drei Fälle wurden täglich studiert, und unmittelbar nach der Operation wurden hohe Werte erhalten, die sich dann allmählich normalisierten. Die Messung des basischen Myelinproteins im Liquor scheint dazu brauchbar zu sein, die Heilung des Hirngewebes nach chirurgischer oder anderer Gehirnläsion zu verfolgen.
    Notes: Summary Myelin basic protein in spinal fluid was measured with a radio-immunoassay method after surgery of brain tumours and posttraumatic brains in thirteen cases. Three cases were studied daily for up to three weeks. Immediately after the operation the values were high but then successively returned to normal. Repeated measurement of the myelin basic protein in spinal fluid seem to be useful for assessing the healing rate of brain tissue after surgery for brain tumours and after other brain damage.
