High systolic blood pressure (BP) was induced in young Wistar rats by daily exposure for 30 mins to environmental stimuli consisting of intense (100 dB) sound of 7500 cps and flashing light (0.3 cps). Maximal BP enhancement was obtained after the application of both these stimuli for 3 consecutive days. Such a hypertensive response was detected 24 hrs, but not 1 hr after the trial. High BP backed to normal 72 hrs after discontinuation of the audiovisual stimulation trials. Clinically effective antihypertensive agents (clonidine, prazosin, propranolol, practolol and metoprolol) as well as a new compound under investigation (cicletanine) were proved active in this model. Normotensive nonstressed rats run in parallel did not show any variation in their BP after administration of the same dose of the drugs assayed. This experimental model of hypertension may be a useful tool not only to test new antihypertensive agents but also to study the intriguing question of the role of stress in the development and maintenance of essential hypertension.

Carbamazepine is a well-established, effective treatment of complex partial seizures and is well tolerated in most patients. The adverse effects of carbamazepine include aplastic anemia, agranulocytosis, pancytopenia, bone marrow depression, thrombocytopenia, cardiac conduction abnormalities, congestive heart failure, and peripheral edema. Hypertension or hypotension has also rarely been documented in patients with either therapeutic or toxic blood levels of carbamazepine. It is possible that carbamazepine-induced hypertension in those with therapeutic blood levels is rarely seen because most of the patients who begin treatment are young and do not have baseline hypertension. The authors describe a patient of African-American descent with a history of controlled essential hypertension who developed severe uncontrolled hypertension when started on carbamazepine. Treatment with additional antihypertensive medications did not reduce his blood pressure. In addition, he developed two episodes of transient neurologic deficits, the symptoms of which consisted of dysarthria, vertigo, and unstable gait. A substantial reduction of his carbamazepine dose resulted in the control of his blood pressure and no recurrence of his symptoms.
