objective: to determine the effects of ramadan fasting on serum levels of stress neurohormones in iranian women with polycystic ovary syndrome (pcos). materials and methods: this study was a clinical trial and was performed during july 2011 (month of ramadan) in royan institute, tehran. a total of 40 women who were aged 20-40 years and known cases of pcos and had no other medical diseases were ...

Plasma concentrations of adrenaline, noradrenaline, and free fatty acids were measured at different stages of cardiac operations in which hypothermia and bypass were used. The rise of adrenaline, noradrenaline, and free fatty acid concentrations in plasma is consistent with the concept that these are important compounds in stress situations such as hypothermia and surgical operations. There is ...

The effects of adrenaline on the potential difference across the cell membrane, on formation of inositol phosphates and on intracellular Ca2+ ([Ca2+]i) were analysed in cells without or with pretreatment with pertussis toxin or phorbol 12-myristate 13-acetate (PMA). In untreated cells, adrenaline leads to a sustained hyperpolarization, a stimulation of Ins(1,4,5)P3 and Ins(1,3,4,5,)P4 formation...

Epidermal growth factor (EGF) stimulates glycogenolysis in mouse liver, but the effect requires concentrations that are only achieved in plasma upon adrenergic stimulation of EGF release from submandibular salivary glands. Thus, we studied the interaction between adrenaline and EGF in liver glycogen metabolism, both in whole animals and in isolated hepatocytes. Adrenaline administered to anesth...

OBJECTIVE To study the effects of continuously administered adrenaline (epinephrine), compared to bolus doses, on the dynamics of cortical cerebral blood flow during experimental cardiopulmonary resuscitation (CPR), and after restoration of spontaneous circulation (ROSC). METHODS Ventricular fibrillation was induced in 24 anaesthetised pigs. After a 5-min non-intervention interval, closed-che...

A trial of a mixture of guanethidine 5% and adrenaline 0.5% (Ganda 5.05) and of guanethidine 3% and adrenaline 0.5% (Ganda 3.05) was conducted on 90 eyes in 53 patients with open-angle glaucoma or ocular hypertension. The cases fell into 5 groups: untreated cases, cases on pilocarpine 1%, on pilocarpine 2%, on pilocarpine 2 to 4% and adrenaline 1%, and on separate guanethidine 5% and adrenaline...

BACKGROUND The effect of vasoconstrictors in prolonged cardiopulmonary resuscitation (CPR) has not been fully clarified. OBJECTIVES To evaluate adrenaline and vasopressin pressure effect, and observe the return of spontaneous circulation (ROSC). METHODS A prospective, randomized, blinded, and placebo-controlled study. After seven minutes of untreated ventricular fibrillation, pigs received ...

Sustained effects of SNS (sympathetic nervous system) and HPAA (hypothalamic-pituitary-adrenal axis) hyperactivity on haemostasis have not been investigated. In the present study, we tested for an association of overnight urinary catecholamine and cortisol excretion with morning plasma levels of fibrinogen, PAI-1 (plasminogen activator inhibitor-1) and D-dimer. Participants (639 male industrial...

AIM To relate the outcome of out-of-hospital cardiac arrest to whether medication with adrenaline (epinephrine) was given and whether patients were intubated. PATIENTS A national survey in Sweden between 1990-1995 among patients suffering out-of-hospital cardiac arrest and in whom resuscitation was attempted. Sixty per cent of ambulance organisations in Sweden participated. DESIGN Prospecti...
