目的:研究 IL-3在 BALB/c 小鼠肺炎支原体(MP)感染模型肺泡灌洗液和血清中的表达,阐明其与 MP 感染的关系。方法36只 BALB/c 裸鼠,随机分为3组,分别为对照组、MP 感染组和克拉霉素组,每组12只。用 PPLO 肉汤培养基 MP,将成功培养的 MP 鼻腔滴入裸鼠建立 MP 感染模型。治疗组用克拉霉素连续治疗8天,收集并分离血清,取其肺组织,收集肺泡灌洗液,采用 ELISA 法测定小鼠血清和肺泡灌洗液中 IL-3水平,肺部组织用中性甲醛固定 HE 染色,观察MP 感染小鼠肺的病变程度。结果成功建立 MP 感染小鼠模型,病理组织学观察结果显示,MP 感染 BALB/c 小鼠后炎症明显,克拉霉素治疗 BALB/c 小鼠炎症逐渐减轻。模型组血清和肺泡灌洗液中 IL-3分别为96.4±8.3 ng/L 和60.9±6.5 ng/L,与对照组比较(203.1±14.5 ng/L,96.3±12.6 ng/L),MP 感染组小鼠血清和肺泡灌洗液中 IL-3水平明显降低(t 血清=19.50,t 肺泡=17.20,P 值均<0.01),用克拉霉素治疗后,小鼠血清和肺泡灌洗液中 IL-3明显升高,分别为175.6±12.5 ng/L 和85.6±10.2 ng/L,差异有统计学意义,t 血清=17.41,t 肺泡=14.62,P 值均<0.01)。结论肺炎支原体感染使小鼠 IL-3水平降低,克拉霉素治疗有一定疗效,IL-3表达可能与 MP 肺炎严重程度有关。

Objective To investigate the expressions of interluekin-3 in BALB/c mice infected by mycoplasma pneumonia (MP)and to clarify the relationship between IL-3 and MP infection.Methods Total 36 BALB/c mice were randomly divid-ed into control group,MP infection group and clarithromycin treatment group.MP infection models were established with the method of dripping cultured MP into nasal cavity of mice.ELISA method was used to assay the levels of IL-3 in the the serum of the mice and bronchoalveolar lavage fluid in various groups.The lung tissue was fixed in formalin for sections,HE staining was performed for the observation of histological changes.Results The MP-infected mouse models were established successfully and MP strains were dripped into the respiratory system of mice.As showed in histopathological observasion re-sults,significantly increased after MP infection and then gradually decreased after clarithromycin treatment.The ELISA re-sults showed that the level of serum and bronchoalveolar lavage fluid of IL-3 of the mice in MP infection group were 96.4± 8.3 ng/L and 60.9 ±6.5 ng/L.Compared with the control group(203.1±14.5 ng/L,96.3±12.6ng/L),serum and bron-choalveolar lavage fluid of mice infected with MP in IL-3 levels were significantly lower (t serum = 19.50,t balf = 17.20,P <0.01),and after treatment with clarithromycin,serum and bronchoalveolar lavage fluid of IL-3 significantly increased,re-spectively(175.6±12.5 ng/L and 85.6± 10.2 ng/L,tserum = 17.41,tbalf = 14.62,P <0.01),the difference was statistically significant.Conclusion IL-3 levels were decreased in mycoplasma pneumonia mice.Clarithromycin treatment had effect on mycoplasma pneumonia infecttion.The expression level IL-3 may be related to the severity degree of MP infection.
