SWR/J mice possess two- to threefold higher 4-methylumbelliferyl sulfate (4MUS), dehydroepiandrosterone sulfate (DHEAS) and estrone sulfate (E1S) sulfatase activities in liver and kidney extracts than do A/J mice. These interstrain activity differences are maintained throughout the 6- to 45-day postnatal period. Characteristics of the hepatic activities of SWR/J mice suggest that all three acti...

INTRODUCTION Civilization changes of the environment shaping the psychosocial resources from rural to urban influence human health. AIM The study aimed to identify the differences due to the place of residence (rural, urban) as far as health resources are concerned (social support, sense of coherence, dehydroepiandrosterone sulfate concentration in plasma) and health in examination stress sit...

Recent reports demonstrate neurotrophic properties of dehydroepiandrosterone sulfate (DHEAS) in men at rest, as well as profound neurotrophic responses to stress in both men and women. Little is known of neuroprotective-neurotrophic effects of DHEAS during stress exposure, either in men or women. This translational study was designed to examine neuroprotective-neurotrophic effects of DHEAS thro...

The shift in cytokine profile during human immunodeficiency virus (HIV) disease progression is influenced by dehydroepiandrosterone sulfate (DHEAS) level. Radioimmunoassay was used to measure plasma DHEAS for 30 treatment-naïve HIV-infected and 30 uninfected individuals. There was a significant negative correlation of viral load with DHEAS level (P<0.05). Further studies of the use of DHEAS lev...

Employee problems arising from mental illnesses have steadily increased and become a serious social problem in recent years. Wood is a widely available plant material, and knowledge of the psychophysiological effects of inhalation of woody volatile compounds has grown considerably. In this study, we established an experimental method to evaluate the effects of Japanese cedar wood essential oil ...

The 24-hr mean plasma concentrations of dehydroisoandrosterone (DHA) and dehydroisoandrosterone sulfate were measured in 11 women with primary operable breast cancer, ages 31 to 78 years, and in 37 normal women, ages 21 to 75 years. In contrast to the marked and progressive decline of DHA and dehydroisoandrosterone sulfate concentration with age in the normal women, the concentrations of both s...

Objective The pathophysiology of major depressive disorder (MDD) is still not well understood. Conflicting results for surrogate. biomarkers in MDD have been reported, which might be a consequence of the heterogeneity of MDD patients. Therefore, we aim to investigate how the severity of depression and various symptom domains are related to the levels of dehydroepiandrosterone sulfate (DHEA-s) i...

PURPOSE This study aimed to determine the effects of the long-term use of dehydroepiandrosterone sulfate (DHEAS) on rat prostates and testes as well as on serum testosterone and DHEAS levels. MATERIALS AND METHODS Thirty male rats aged 4 to 5 months were studied. A DHEAS suspension of 5 mg/kg per rat was administered orally to the 15 rats in the experimental group 5 times a week, whereas sali...

The effects of chronic stressors on glucocorticoid levels are well described in laboratory rodents, but far less is known about the effects of chronic stressors on wild animals or on dehydroepiandrosterone (DHEA) levels. DHEA can be produced by the adrenal cortex and has prominent antiglucocorticoid properties. Here, we examined wild songbirds to elucidate the relationship between chronic preda...

Serum adrenal androgens (AAs), including androstenedione (Δ4A) and dehydroepiandrosterone sulfate (DHEAS), have been reported to be lower in female rheumatoid arthritis (RA) patients with early disease. Few data are available on hormonal status of women before the onset of clinical rheumatoid arthritis (pre-RA). A broad baseline panel of serum adrenal and sex steroids was compared in 36 female ...
