ABSTRACT

Objective:

To investigate the effects of sivelestat sodium on early inflammatory response and pulmonary edema in rats with smoke inhalation-induced lung injury.

Methods:

Seventy-five Sprague-Dawley rats were randomly divided into control group, model group, low-dose group, middle-dose group and high-dose group. The smoke inhalation model was continued except for the control group. The rats were given intraperitoneal injection of normal saline, cevicell sodium 10 mg/kg, 20 mg/kg and 30 mg/kg. The general condition and lung tissue were observed after 24 hours.

Results:

Compared with the control group, rats in each group had a certain degree of lung injury, alveolar wall thickening, alveolar interstitial hyperemia, etc. The alveolar septal thickness, lung tissue wet-dry (W/D) level, the incidence of edema and the levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), neutrophil elastase (NE) and myeloperoxidase (MPO) in the model group were significantly higher than those of the other 4 groups. The lung function recovery was highest in the low dose group and the alveolar septal thickness was the highest among the dose group. The alveolar wall thickening incidence of W/D level and pulmonary edema in lung tissue in the low dose group were (6.76±0.40)μm, (5.18±0.13) and 40.00%, respectively, and the levels of TNF-α, IL-6, NE and MPO were (19.62±0.83)pg/L, (9.41±0.25)pg/L, (6.23±0.18)μg/L and (30.64±0.87)pg/L, significantly better than the middle dose group and high dose group ( P<0.05).

Conclusions:

Sivelestat sodium can significantly affect the smoke inhalation lung injury, and improve the recovery of liver function, which can significantly reduce the incidence of inflammation and pulmonary ede-ma in the lung, but its therapeutic effect and drug delivery. There was a significant association between doses and therapeutic effect, in the case of rats, a dose of 10 mg/kg was the best for treatment.
