- چکیده:
- چکیده انگلیسی: Objective: Inflammation is one of the major components of asthma. Our aim was to evaluate the effects of C. sativus extract on total and differential white blood cells (WBC) count in lung lavage fluid (LLF) of ovalbumin-sensitized rats.
Materials and Methods: Forty rats were divided into five groups (n = 8 for each group) as control (C), sensitized with injection and inhalation of ovalbumin (OA) alone (S), and three groups of sensitized and treated with different doses of C. sativus extract (S+50EX, S+100EX, and S+200EX groups). Total and differential WBC counts of LLF were evaluated in control, sensitized, and treated sensitized groups.
Results: Total WBC count, neutrophil, and eosinophil percentage in LLF were increased in sensitized animals compared with the control group (p<0.001). Treatment of sensitized animals with all doses of the extract significantly reduced WBC number and the percentage of neutrophil and eosinophil compared with the sensitized animals (p<0.01–0.001).
Conclusion: According to these results, the extract of C. sativus could be effective on alleviating lung inflammatory cells specially eosinophils in lung lavage of sensitized animals which may indicate a preventive effect of this plant on lung inflammation in asthma.- انتشار مقاله: 25-02-1392

- چکیده:
- چکیده انگلیسی: Objective: Asthma is a chronic inflammatory disease of the respiratory airways distinguished by edema and infiltration of inflammatory immune cells. To test our hypothesis about the anti-inflammatory effect of saffron, we examined effects of Crocus sativus (C. sativus) extract as a prophylactic anti-inflammatory agent in sensitized rats.
Materials and Methods: To induce experimental asthma, rats were sensitized with injection and inhalation of ovalbumin (OA). Forty male Wistar rats were divided into 5 groups (n=8 for each): control, sensitized (asthma), and sensitized and pretreated with three different concentrations of extract, 50, 100, and 200 mg/kg, 2 times a week (group asthma+50EX, group asthma+100EX, and group asthma+200EX). After 32 days, total white blood cells (WBC) counts, red blood cells (RBC), and platelet counts in blood were examined.
Results: Total WBC number and eosinophil and neutrophil percentage in blood were increased, but lymphocyte decreased in sensitized animals compared with those of control group (pConclusion: Our findings indicated that the extract of C. sativus could be useful to prevent asthma as an anti-inflammatory treatment.- انتشار مقاله: 18-11-1391
