The endocrine disruptor compounds (EDC) (e.g. chlorobenzenes (ClB), phenurone (PU), monurone (MU), diurone (DU)) are accumulative, lipophilic, chemical pollutants that can disturb the homeostatic balance and exert tumorigenic effects. The aim of the present study was to investigate the effects of EDCs on the adrenocorticotropic hormone (ACTH) and prolactin (Prl) release in primary cell cultures derived from rat normal adenohypophysis and prolactinoma.The...

Introduction: Physical inactivity, i.e. sedentary life style increases circulatory disease risk. Carbon monoxide and nitric oxide produced by the heme oxygenase (HO) and by the constitutive nitric oxide synthase (cNOS) protect circulation. In contrast, the enhanced level of the matrix metalloproteinase (MMP) augments cardiovascular risks. We examined the actions of recreational physical exercise on the expression of these enzyme systems in conjunction with cardiovascular prote...

Decreased bone mineral density (BMD) and disturbances in glucose metabolism are common complications of Cushing’s disease. Many recent studies have shown that hyperinsulinemia in type 2 diabetes mellitus (DM) may lead to higher BMD as compared to healthy individuals. The aim of the present study was to investigate the possible relationships between BMD, serum markers of bone metabolism and plasma cortisol concentrations. The second objective was to determine whether the p...
