[Level of dopamine beta-hydroxylase activity in subarachnoid hemorrhage treated conservatively and surgically]

The activity of the catecholaminergic system was studied by analysis of changes in the activity of dopamine beta-hydroxylase (DBH) in patients after subarachnoid haemorrhage treated conservatively or surgically. The activity of DBH was analysed in a group of 20 conservatively treated patients and 41 treated surgically, with comparison to 50 controls. DBH activity was determined on days 1-3 after subarachnoid haemorrhage, in the second week, and before and after operation. In the period of the investigations changes were noted in DBH activity depending on the clinical state of the patients, and no direct effect of the operation was noted on DBH activity in the serum.
