background hygiene and maintenance of removable prostheses are very important for the oral health. elderly patients are not capable of this affair since they might have diseases in addition to being old; thus, they require new alternative methods. objectives the purpose of this study was to compare the disinfecting effects of three substances, water, normal saline and denture cleaning tablets c...

BACKGROUND Inhaled hypertonic saline is used for bronchial challenge and sputum induction in patients with chronic obstructive pulmonary disease (COPD). We studied the effects of saline aerosol inhalation before each exercise session in an 8-week pulmonary rehabilitation program. METHODS This was a double-blind randomized parallel controlled trial, conducted at an out-patient clinic. Sixty-ei...

Intestinal ischaemia/reperfusion causes formation of reactive oxygen intermediates which lead to mucosal cell injury. Glutathione, a scavenger of reactive oxygen intermediates, protects tissues from reactive oxygen intermediate-mediated cell injury. Nitric oxide is a lipophilic gas and its synthesis is stimulated by ischaemic conditions. In this experimental study, we aimed to investigate the r...

conclusions we conclude that intraperitoneal hydrocortisone instillation caused leukocytosis and is thus suggested not to be used in immune-compromised patients. results the study was completed by 120 patients. patients who received intraperitoneal hydrocortisone and hydrocortisone plus bupivacaine had higher white blood cell (wbc) count (p < 0.0001). the patients were similar with respect to d...

BACKGROUND Occlusion of central venous catheters is one of the limiting factors in using them. Heparinized saline solution is the standard solution used for keeping the catheters open. OBJECTIVES This study aimed to determine the effect of heparin saline solution and normal saline in maintenance of patency of central venous catheters. PATIENTS AND METHODS This double-blind study was perform...

Conscious rabbits infused intravenously (i.v.) with isotonic saline at 1.5 to 1.8 ml/min for 24 hours had greater pressor responses to norepinephrine (NE) than did normal control rabbits. Infusion of the angiotension II (ANG II) antagonist [Sar1, Ile8] ANG II did not decrease the exaggerated pressor responses to NE in saline-infused rabbits. Measurements of cardiac output (CO) as well as the pr...

limited evidence has been obtained concerning the beneficial effects of autologous serum therapy in treatment of skin disorders particularly chronic urticaria. in the present study, we have assessed the effect of this treatment method in patients with chronic urticaria (cu). this randomized single-blind controlled trial was performed on fifty consecutive patients with chronic urticaria. the pat...
