This study was designed to determine the effect of in vivo hydrocortisone on subpopulations of lymphoid cells in normal humans. Subjects received a single intravenous dose of either 100 mg or 400 mg of hydrocortisone, and blood was drawn at hourly intervals for 6 h, and then again at 10 and 24 h after injection. Profound decreases in absolute numbers of circulating lymphocytes and monocytes occ...

OBJECTIVE Major depressive disorder (MDD) has been associated with hypercortisolism, reduced glucocorticoid feedback sensitivity, and impaired memory function. In healthy subjects, administration of hydrocortisone impairs declarative memory. The aim of this study was to examine the effects of acute hydrocortisone administration on memory retrieval in MDD patients and healthy controls. We furthe...

BACKGROUND Low cortisol concentrations in premature infants have been correlated with increased severity of illness, hypotension, mortality, and development of bronchopulmonary dysplasia. A total of 360 mechanically ventilated infants with a birth weight of 500 to 999 g were enrolled in a randomized, multicenter trial of prophylaxis of early adrenal insufficiency to prevent bronchopulmonary dys...

BACKGROUND Previous investigations and meta-analyses on the effect of glucocorticoids on mortality in septic shock revealed mixed results. This heterogeneity might be evoked by genetic variations. Such candidate is a promoter polymorphism (-94ins/delATTG) of the gene encoding the ubiquitous transcription-factor nuclear-factor-κB (NF-κB) which binds to recognition elements in the promoter of sev...

background: this randomized controlled study was designed to compare the postoperative analgesic efficacy of intraperitoneal ketamine versus bupivacaine in patients undergoing laparoscopic cholecystectomy. methods: we randomly divided 60 patients undergoing elective laparoscopic cholecystectomy into two groups. the intervention group patients received intraperitoneal ketamine (0.5 mg/ kg) dilut...

Background: Chronic kidney disease affects the structure and function of kidneys over a specific period time. It is worldwide public health related problem. usually associated with increasing age, hypertension, diabetes, cardiovascular lack exercise.
 Materials Methods: was cross-sectional observational study conducted at Nobel Medical College Teaching Hospital. A total 150 patients were e...

BACKGROUND Hydrocortisone is widely used in patients with septic shock even though a survival benefit has been reported only in patients who remained hypotensive after fluid and vasopressor resuscitation and whose plasma cortisol levels did not rise appropriately after the administration of corticotropin. METHODS In this multicenter, randomized, double-blind, placebo-controlled trial, we assi...

The inhibitory effects of ATP and adenosine on the nerve-mediated contractile responses of isolated sartorius muscle of the frog, Rana ridibunda, evoked by electrical field stimulation (EFS) were studied using pharmacological organ-bath technique. The effects of hydrocortisone applied in vitro and in vivo on contractility of sartorius muscle were also examined. ATP (100 microM) significantly re...

On the basis of serial studies the responsiveness of leukocytes and lymphocytes from asthmatic donors to catecholamines was increased during high dose corticosteroid therapy. Similar changes were observed in the cells of normal control subjects given 200 mg of hydrocortisone intravenously. The increase in responsiveness did not appear to be due to changes in lymphocyte subpopulations although t...
