1. Ten patients with essential hypertension and ten healthy men were submitted to mental stress consisting of Kraepelin's arithmetic test combined with noise. Concentrations of plasma and urine catecholamines and of their metabolites as well as plasma renin activity before and after the test were studied. 2. In both groups a significant increase of noradrenaline and adrenaline in blood and nora...

Objective. To report the unusual case of an adrenal lymphangioma presenting in a patient with an adrenal cystic lesion and biochemical testing concerning for pheochromocytoma. The pertinent diagnostic and imaging features of adrenal lymphangiomas are reviewed. Methods. We describe a 59-year-old patient who presented with hyperhidrosis and a 2.2 by 2.2 cm left adrenal nodule. Biochemical evaluat...

A right adrenal tumor was found incidentally during abdominal computed tomography exam in a 51-year-old female patient, who had had diabetes and hypertension for more than 10 years. The computed tomography scan was arranged for possible pancreatic lesion by a neurologist. Norepinephrine level was high in the plasma and urine. Vanillylmandelic acid level was elevated in the urine. Diurnal cortis...

BACKGROUND Stress is a normal part of everyday life but chronic stress can lead to a variety of stress-related illnesses including hypertension, anxiety, and depression. In the present investigation, standardized leaf extract of Epipremnumaureum was evaluated for its anti-stress potential. MATERIALS AND METHODS For the evaluation of anti-stress activity, groups of mice (n = 6) were subjected ...

A 34-year-old 13-week pregnant woman presented with hypertension refractory to medical therapy and on workup was found to have a right adrenal mass. Due to her persistent increased blood pressure she was advised urinary vanillylmandelic acid (VMA) and its level was raised. MRI of the abdomen showed a well-circumcised lesion in the right adrenal of 3.0×2.5 cm suggestive of pheochromocytoma. The ...

Since 1960 we have diagnosed phaeochromocytoma (paraganglioma) in 10 children. The cases include a 15 year old girl who over a three year period presented with multiple paragangliomata and an associated malignant carotid body tumour. All children were hypertensive, eight of 10 presenting with severe headaches. Diagnosis was based on finding a raised urinary vanillylmandelic acid excretion and p...

An increased number of adrenal tumors are now diagnosed due to the increased number of abdominal CT scans being performed. We present the first case of malignant lymphoma combined with clinically "silent" pheochromocytoma in the same adrenal gland. An abdominal CT scan demonstrates unilateral adrenal lesion which suggests pheochromocytoma or adrenal carcinoma. Laboratory examinations revealed a...

Purpose: Anethum graveolens Linn. (Umbelliferae, A. graveolens) is a widely used spice with a long history of traditional medicinal use for the treatment of various ailments. The present study examines the anti-stress and cognition-improving effects of A. graveolens extract in a rat model. Methods: Urinary vanillylmandelic acid (VMA) and ascorbic acid were estimated as biomarkers for evaluating...
