摘 要:目的研究奥伐尼对芥子气所致皮肤损伤的保护作用。方法采用32和128 g/L芥子气5μl于KM小鼠右耳内侧染毒,建立两种损伤程度的小鼠耳郭染毒皮肤损伤模型。在32 g/L芥子气染毒模型中,染毒前20 min于小鼠右耳内侧涂抹奥伐尼0.125、0.25和0.5 mg/耳,或染毒前30 min灌胃给予吲哚美辛10 mg/kg,染毒24 h后,观察各组耳郭肿胀程度,制备耳郭皮肤切片观察皮肤组织病理变化。在128 g/L芥子气染毒模型中,小鼠右耳给予奥伐尼0.25 mg/耳或灌胃给予吲哚美辛10 mg/kg,染毒24 h后观察各组耳郭肿胀程度。结果奥伐尼可显著降低32 g/L芥子气所致耳郭肿胀,并显著改善皮肤炎症、坏死等病理变化,但对128 g/L芥子气所致耳郭肿胀无明显影响。结论奥伐尼对低剂量芥子气染毒所致皮肤损伤具有显著的保护作用。Objective To study the protective effects of olvanil on sulfur mustard (SM)-induced cutaneous injury. Methods To establish mouse ear model of SM-induced cutaneous injury, KM mice right ears were exposed to 5 μl of 32 g/L or 128 g/L SM, re- spectively. Then we evaluated the protective effect of olvanil against SM-induced cutaneous injury with these two concentrations. For mice exposed to 32 g/L SM, olvanil (0. 125, 0. 25 and 0. 5 rag/ear, topically) or indometacin (indomethaein, 10 mg,/kg, po) were administrated 20 min or 30 min before SM exposure, respectively. After 24 h SM exposure, ear tissue was harvested and weighted, and the histopathologieal analysis was conducted. Similarly, for mice exposed to 128 g/L SM, olvanil (0. 25 mg/ear, topically) or indom- ethaein ( 10 mg/kg, po) were administrated, and ear tissue was harvested and weighted. Results Olvanil significantly inhibited 32 g/L SM-indueed ear edema, cutaneous inflammation and necrosis, while no influence were observed on 128 g/L SM-indueed cutaneous injury. Conclusion Olvanil shows remarkable protective effect on cutaneous injury induced by SM of low concentration.
