中文摘要: 目的:研究桉柠蒎肠溶软胶囊对脂多糖(LPS)诱导小鼠急性肺损伤(ALI)的改善作用。方法:将60只小鼠随机分为空白对照组、模型对照组和桉柠蒎肠溶软胶囊低、中、高剂量组(100、300、900 mg/kg),每组12只。给药组小鼠ig相应药物,空白对照组和模型对照组小鼠ig等体积生理盐水(0.1 mL/10 g)。给药2 h后,除空白对照组外,其余各组小鼠均采用LPS雾化吸入的方法诱导ALI模型。造模6 h后,处死小鼠取肺泡灌洗液(BALF)和肺组织,镜下观察肺组织形态学变化;血细胞计数板计算BALF中总细胞数和瑞氏-吉姆萨染色后计算BALF中中性粒细胞数;二喹啉甲酸法检测BALF上清液中总蛋白浓度;酶联免疫吸附法检测BALF上清液中肿瘤坏死因子α(TNF-α)、白细胞介素6(IL-6)含量。结果:与空白对照组比较,模型对照组小鼠肺组织发生明显病理学损伤,肺水肿严重;BALF中总细胞数、中性粒细胞数和BALF上清液中总蛋白浓度以及TNF-α、IL-6含量均显著增加(P<0.01)。与模型对照组比较,桉柠蒎肠溶软胶囊高剂量组小鼠肺组织病理损伤明显改善,BALF中总细胞数、中性粒细胞数和BALF上清液中总蛋白浓度以及TNF-α、IL-6含量均显著减少(P<0.05);其余各组差异无统计学意义(P>0.05)。结论:高剂量桉柠蒎肠溶软胶囊能明显改善LPS诱导的小鼠ALI。
英文摘要: OBJECTIVE: To investigate the improvement effect of Eucalyptol enteric soft capsule on mice with lipopolysaccharide(LPS)-induced acute lung injury (ALI). METHODS: 60 mice were randomly divided into blank control group, model control group, Eucalyptol enteric soft capsule low-dose, medium-dose, high-dose groups (100, 300, 900 mg/kg), 12 in each group. Mice in administration groups were intragastrically given relevant medicines, mice in blank control group and model control group were intragastrically given equal volume of normal saline (0.1 mL/10 g). After 2 h of administration, except for the blank control group, ALI was induced in other groups by atomized LPS. After 6 h of modeling, the mice were sacrificed, alveolar lavage fluid (BALF) and lung tissue were taken. Morphological changes of lung tissue were observed under microscope; number of total cells, neutrophils in BALF were calculated by blood cell count plate and staining by wright-giemsa respectively. Total protein concentration in BALF supernatant was detected by BCA method; TNF-α, IL-6 contents in BALF supernatant were determined by enzyme-linked immunosorbent assay. RESULTS: Compared with blank control group, lung tissue of mice in model control group showed obvious pathological damage and severe pulmonary edema; number of total cells, neutrophils in BALF, total protein concentration and TNF-α, IL-6 contents in BALF supernatant were significantly increased (P<0.01). Compared with model control group, pathological damage in lung tissue of mice was obviously improved in Eucalyptol enteric soft capsule high-dose group, number of total cells, neutrophils in BALF, total protein concentration and TNF-α, IL-6 contents in BALF supernatant were significantly decreased (P<0.05); and there were no significant differences in other groups (P>0.05). CONCLUSIONS: High-dose Eucalyptol enteric soft capsule can obviously improve LPS-induced ALI of mice.
