Abstract：
:The aetiology of incomplete adrenergic denervation and reduction in the number and caliber of the cerebral vessels in hydrocephalus is still obscure. Stretching of the blood vessels alone is far from explaining these major vascular changes. Previous studies have shown that increased lipid peroxidation produces toxic effects on vessels. This experimental study was designed to investigate the possible aetiology of vascular changes in hydrocephalic rats with special reference to lipid peroxidation. Hydrocephalus was induced by injecting 50 mg/Kg sterilized kaolin suspension into the cisterna magna in 10 rats (Group A). A sham operation was performed for Group B. After three weeks the rats were anaesthetized and perfused transcardially. The brains were dissected, and cut to visualize the degree of hydrocephalus. The arteries of the circle of Willis were removed for light microscopic examination and the brains were kept for the measurement of lipid peroxidation levels. Light microscopic studies of cerebral arteries in hydrocephalic rats revealed spastic vessels with folding and corrugation of the lamina elastica. The level of lipid peroxidation in group A (260 +/- 9.129 nmol TBAR/gr wet tissue) was significantly higher than that of group B (106 +/- 3.59 nmol TBAR/gr wet tissue). It is suggested that vascular changes observed in hydrocephalic rats may be due to the high level of lipid peroxidation, which in turn may be the consequence of ischaemia caused by the hydrocephalus related stretching of cerebral vessels.
