Regional cerebral blood flow, glucose metabolism, protein synthesis, serum protein extravasation, and content of biochemical substrates in stroke-prone spontaneously hypertensive rats.

Journal Article

Stroke-prone spontaneously hypertensive rats with arterial blood pressure above 210 mmHg were taken for the present study after appearance of neurological symptoms. Regional cerebral blood flow, glucose metabolism, and protein synthesis rate were evaluated on the same brain section by means of triple-labelled autoradiographic techniques. Consecutive sections were used in the pictorial presentation of glucose, ATP, and serum protein extravasation. In addition, NADH-fluorescence was recorded. Two different patterns of hypertension-induced brain lesions could be distinguished: in two animals sharply demarcated cysts were visible in the cortical grey matter. In these animals no regional inhomogeneities of flow and metabolism were present remote from the infarct. In contrast, in three animals cysts were located in the white matter, leading to pronounced hemodynamic and metabolic disturbances throughout the brain. It is concluded that edema-induced brain swelling was the main cause for reduction in blood flow and metabolism.
