The acidophilic nature of neuronal Golgi impregnation.

The mechanisms of Golgi impregnation of neurons has remained enigmatic for decades. Recently, it was suggested that divalent (di)chromate anions play a role in the Golgi impregnation process. Therefore, we incubated slices of (para)formaldehyde-fixed rat brain tissue in solutions of potassium (di)chromate, phosphate, chloride or nitrate at pH 6 or 7.

[Comparative analysis of changes in cerebrospinal fluid pressure and ocular fundus findings in traumatic subarachnoidal hemorrhage].

In this paper we gave the analysis of the height of CNS fluid pressure at patients with traumatologic subarachnoidal hemorrhagy and changes in fundus shown as preretinal hemorragies. By analysing 15 patients we could some to the conclusion that CNS fluid pressure, measured in lumbal did not follow the appearance of preretinal hemorragies. Or in other words, the appearance of preretinal hemorragies was not in direct dependance of the CNS fluid pressure.
