Abstract
|
|
|
The effects of unilateral occlusion of the common carotid simultaneous occlusion of vertebral arteries on the cerebral lactic acid production were evaluated on the 50 rabbits.
The lactic acid concentration of the slices of rabbit brain cortex, thalamus, cerebellum and medulla oblongata which ligated only right common carotid artery or that simultaneously ligated right vertebral artery for 5 or 15 minutes respectively were estimated by Barker and Summerson method. The results obtained were as follows:
1) The lactic acid production was not influence in tfie groups of single occlusion of the common carotid artery.
2) In the groups of simultaneous occlusion of common carotid and vertebral arteries, the lactic acid production of cerebral cortex and medulla oblongata increased but residual cerebral regions still remained within normal limits.
