        摘   要   目的:研究小叶三点金提取物的抗炎作用及其机制,为该药用植物的进一步开发应用提供实验依据。方法:采用二甲苯、
        冰醋酸、角叉菜胶建立小鼠急性炎症模型,以地塞米松为阳性对照(0.005 g/kg),考察灌胃不同剂量小叶三点金提取物(50、30、15
        g/kg)对二甲苯致正常小鼠和肾上腺摘除小鼠耳肿胀、冰醋酸致正常小鼠腹腔毛细血管通透性增加、角叉菜胶致正常小鼠和肾上
        腺摘除小鼠足肿胀的抑制作用,并对角叉菜胶致炎模型肾上腺摘除小鼠足趾炎性部位中的丙二醛(MDA)、超氧化物歧化酶
        (SOD)、一氧化氮(NO)水平进行检测;另设空白组小鼠为对照(灌胃等体积水)。结果:与空白组比较,小叶三点金提取物高、中剂
        量组正常小鼠和肾上腺摘除小鼠耳肿胀度均显著降低,而耳肿胀抑制率显著升高;小叶三点金提取物各剂量组正常小鼠腹腔毛细
        血管通透性均显著降低;小叶三点金提取物高、中剂量组正常小鼠和肾上腺摘除小鼠足肿胀度均显著降低,而足肿胀抑制率显著
        升高(P<0.05或P<0.01);小叶三点金提取物高、中剂量组肾上腺摘除小鼠足趾炎性部位中MDA、NO水平均显著降低,SOD水平
        均显著升高(P<0.05)。结论:小叶三点金提取物对小鼠急性炎症有明显抑制作用;其抗炎作用机制与降低MDA、NO水平并提高
        SOD水平有关,且该抗炎作用的发挥不依赖于下丘脑-垂体-肾上腺轴系统。

        ABSTRACT    OBJECTIVE:To study the anti-inflammatory effect and its mechanism of the extract of Dcsmodium microphyllum,
        so as to provide experiment reference for further study of D. microphyllum. METHODS:Acute inflammatory model was established
        by xylene,glacial acetic acid and carrageenan. Using dexamethasone as positive control (0.005 g/kg),inhibitory effects of
        intragastric different doses of the extract of D. microphyllum(50,30,15 g/kg)on xylene-induced ear swelling in normal mice and
        adrenalectomized mice,glacial acetic acid-induced permeability increasing of abdominal capillaries in normal mice,carrageenan-
        induced paw swelling in normal mice and adrenalectomized mice were investigated. The levels of MDA,SOD and NO in the
        inflammatory tissue of toes of adrenalectomized mice were detected in carrageenan-induced inflammation model. Blank group was
        set for control(ig. equal volumn of water). RESULTS:Compared with blank group,ear swelling degree of normal mice and
        adrenalectomized mice were decreased significantly in D. microphyllum extract high-dose and medium-dose groups while inhibitory
        rate of ear swelling was increased significantly;the permeability of abdominal capillaries of normal mice was significantly
        decreased in D. microphyllum extract groups;the swelling degree of toes in normal mice of D. microphyllum extract high-dose and
        middle-dose groups and adrenalectomized mice were significantly decreased while inhibitory rate of toe swelling was increased
        significantly (P<0.05 or P<0.01). The levels of MDA and NO in the toe inflammatory site of adrenalectomized mice were
        decreased significantly in D. microphyllum extract high-dose and medium-dose groups,while the level of SOD was increased
        significantly (P<0.05). CONCLUSIONS:D. microphyllum extract can inhibit acute inflammation in mice significantly. Its
        anti-inflammatory mechanism is associated with decreasing MDA and NO while increasing SOD levels,and the anti-inflammatory
        effect does not depend on the hypothalamus-pituitary-adrenal axis system.
