Oh, eettre: To investigate salbutamol effects on histopatholopc features of acute resturatory distress syndrome (ARDS). Methods: ARDS was designed in Wistar albino male rats, 250300 g in weight, by intratracheal instillation of physiological saline solution. Anesthezied and tracheotomized rats with ARDS were pressure controlledventilated. At the end of the 210 minutes, two hours past and nebulized salbutamol inhalation was tried. All rats were assigned to two groups: Group 1 (n=10) control group, given no treatment, group,2 (n=10) received salbutamot Nebulized salbutamol inhalation was given in the dosage of 0, 15 mg/kg/dose. Rats were continued to be on ventilator through the experiment. After the last inhalation, two hours past and their both lungs were excised for histopathological examination. Results: Rat model ARDS had similar histopathological appearance occuring during the acute phase of the acute respiratory distress syndrome in humans. A statistical difference was seen between control and salbutamol group (P=0.002) for HM. The margination of leukocytes was decreased in salbutamol group. The difference was significant (P<0.042). Hemorrhage and interstitial/intraakeolar edema were much lower in 0.15 mg/dose nebulized salbutamol group than that of control group. There was a significant difference statistically between two groups (P<0.001). Conclusions: Inhaled salbutamol therapy for ARDS is may be associated with the improvement of inflamation. Besides known effects of salbutamol, the reducing of infiltration of polymorphonuclear neutrophil leukocytes, interstitial/intraalveolar edema, perivascular and/or intraalveolar hemorrhage and hyaline membrane formation should be emphasized.
