Sex differences in adaptation and coping were studied by comparing neuroendocrine and psychological functions in male and female high-school students during 2--3 hr of routine school work (control condition) and a 6-hr matriculation examination (stress condition). In the control condition sex differences were slight and nonsignificant. During examination stress, the urinary excretion of cortiso...

OBJECTIVE To investigate the effect of valproic acid on plasma levels of risperidone and its active metabolite, 9-hydroxyrisperidone under steady state conditions in 12 schizophrenic patients. METHODS The efficacy and tolerability for the combination treatment of valproic acid and risperidone were examined. RESULTS The addition of valproic acid to risperidone significantly reduced total sco...

Adrenergic response following infusions of yohimbine or normal saline was evaluated in 9 control subjects, 8 patients suffering from a major depressive episode (MDE), and 12 patients suffering from concurrent MDE and panic disorder (MDE + P). Blood was drawn at -20, 0, 5, 10, 20, 45, and 90 min following the infusions, and assayed for norepinephrine (NE) and 3-methoxy-4-hydroxy-phenyl glycol (M...

objective(s) the aims of present study were to elucidate the effect of nahs as a h2s donor on precontracted rat trachea smooth muscle, role of epithelium and nitric oxide in this action. materials and methods tracheal rings from male adult wistar rats were isolated and mounted in an organ bath containing krebs–henseleit solution under 1.5 g resting tension and contractions were recorded isometr...

from june 1992 to march 1993, a group of patients suffering from different types of warts were treated with intralesional injections of bleomycin sulfate. this study reviews the literature concerning this modality of treatment and the pathophysiology and immunohistopathology of warts and options for treatment. in this prospective study, a combination of a i mg/ml solution of bleomycin in distil...

results in all the groups, complete hemostasis occurred. hemostasis times of different concentrations of ferric sulfate were significantly less than those of the control group (p < 0.001). objectives this study attempted to determine the haemostatic effect of ferric sulfate and compare it with the standard method (suturing technique). materials and methods in this animal model study, 60 male wi...

aluminum sulfate nano structures have been prepared by solution combustion synthesis using aluminum nitrate nonahydrate (al(no3)3.9h2o) and ammonium sulfate ((nh4)2so4). the resultant aluminum sulfate nano structures were calcined at different temperatures to study thermal  decomposition of aluminum sulfate. the crystallinity and phase of  the as-synthesized and calcined samples were characteri...

The concentrations of homovanillic acid (HVA), 5-hydroxyindolylacetic acid (5-HIAA), and 4-hydroxy, 3-methoxyphenylethylene glycol (MHPG) were estimated in the lumbar cerebrospinal fluid (CSF) of control subjects and in some patients who probably, and others who definitely, suffered from multiple sclerosis (MS). In the control group, the concentration of HVA was lower in people who underwent lu...
