摘  要:目的研究人参皂苷预处理对内毒素(脂多糖)所致急性肺损伤(ALI)大鼠的保护机制。方法按雌雄对半将成年大鼠按体重随机分为4组(每组10只):空白组、模型组、人参皂苷组和对照组。造模前3天,人参皂苷组腹腔注射人参皂苷100 mg·kg^(-1),每天1次,连用3 d;造模前1天,对照组腹腔注射甲强龙40 mg·kg^(-1)。空白组给与等量的0.9%Na Cl。3组均(空白组以外)腹腔注射脂多糖5 mg·kg^(-1)复制大鼠ALI模型。检测大鼠R动脉血氧合指数(PO_2/FiO_2)与肺泡灌洗液(BALF)中蛋白含量,用ELLISA检测大鼠BALF中肿瘤坏死因子α(TNF-α)和白细胞介素-6(IL-6)和白细胞介素-10(IL-10)表达水平。结果 PaO_2/FiO_2:与空白组的(485.49±20.71)mmHg比较,模型组为(269.29±13.61)mmHg,差异有统计学意义(P<0.01)。与模型组比较,人参皂苷组和对照组分别为(379.74±15.06),(398.08±16.89)mmHg,差异均有统计学意义(均P<0.01)。BALF中蛋白含量:与空白组的(39.00±5.00)μg·mL^(-1)比较,模型组为(3.69±3.86)μg·mL^(-1),差异有统计学意义(P<0.01)。与模型组比较,人参皂苷组和对照组分别为(77.00±6.00),(97.00±11.00)μg·mL^(-1),差异均有统计学意义(均P<0.01)。BALF中TNF-α、IL-6和IL-10水平:与空白组的(218.85±7.36),(10.84±1.66),(50.00±7.21)ng·L^(-1)比较,模型组分别为(505.78±7.60),(61.55±4.08),(94.76±3.58)ng·L^(-1),差异均有统计学意义(均P<0.01)。与模型组比较,人参皂苷组和对照组分别为(346.42±11.24),(338.14±5.37)ng·L^(-1);(42.49±1.26),(40.07±2.60)ng·L^(-1);(114.22±2.58),(119.07±4.08)ng·L^(-1),差异均有统计学意义(均P<0.01)。结论人参皂苷可能通过上调IL-10的表达及下调TNF-α与IL-6的表达来保护大鼠的急性肺损伤。Objective To study the protective effects of ginsenoside on endotoxin of lipopolysaccharide (LPS) - induced acute lung injury (ALl) in rats. Methods Adult rats were divided into 4 groups (10 rats in each group) : blank group (0. 9 % NaCl) , model group, ginsenoside group (100 mg· kg-1)and control group( methylprednisolone 40 mg· kg-l). Intraperitoneal injection of LPS (5 mg· kg-1 ) to prepare the ALI model of rats. The drugs given at the time of 3 d and 1 d respectively before established model in ginsenoside group and control group. The oxygenation index (PO2/FiO2 ), and protein content in bronchoalveolar lavage fluid (BALF) were detected. The levels of tumor necrosis factor α(TNF - α),interleukin 6( IL- 6 ) and interleukin 10 (IL- 10 )in BALF were detected by ELLISA. Results PaO2/FiO2: Compared with the blank group (485.49 ±20. 71 ) mmHg,model group was (269. 29 ± 13.61 ) mmHg with statistically significant (P 〈0. 01 ). Compared with the model group,ginsenoside group and control group were (379.74 ± 15.06), (398.08 ± 16.89) mmHg with statistically significant ( all P 〈 0. 01 ). Protein content of BALF: Compared with the blank group ( 39.00 ± 5.00 ) μg · mL- 1, model group was (3.69 ± 3.86) μg · mL- 1 with statistically significant (P〈0.01). Compared with the model group, ginsenoside group and control group were (77.00 ± 6.00), (97. 00 ± 11.00) μg · mL- 1 with statistically significant ( all P 〈 0. 01 ). Levels of TNF -αt, IL - 6 and IL - 10 of BALF:Compared with the blank group (218.85 ±7.36), ( 10. 84 ± 1.66), (50. 00 ±7.21) ng · L^-1 , model group were (505.78 ± 7.60 ), ( 61.55 ± 4. 08 ), ( 94. 76 ± 3.58 )ng · L^-1with statistically significant ( all P 〈 0. 01 ). Compared with the model group, ginsenoside group and control group were (346. 42 ± 11.24), ( 338. 14 ± 5.37 ) ng · L^-1 ; (42. 49 ± 1.26 ), (40. 07 ± 2. 60 ) ng
